Abstract

This application describes a remote laboratory system for learning electrical, electronic, and control circuits, through which students can perform basic experiments using direct current and alternating current without having to be in the laboratory to perform these experiments in person. This is because the present invention has a server that uses the NI ELVIS system and the Internet together with specially designed equipment. Using these components, it is possible to conduct experiments through a workstation. It is also worth mentioning that the development of a web platform is an important part of interacting with the remote laboratory (mainly with the workstation) because it allows users to make reservations and download applications through which they can virtually access practices and continue to perform these practices, so that learning will be more educational and easier to achieve.

Description

Remote laboratory system for study of electrical, electronic and control circuits and method for its implementation

Purpose of invention

The main purpose of the present invention is to provide a remote laboratory system that allows different physical devices to interact with users through an interface or web platform, aiming to ensure that users can configure different laboratory technology tools under autonomous pre-determined conditions, Enables them to carry out different physical experiments without needing to be present while the experiments are taking place, in this case the system is suitable for electrical and electronic circuits. While the laboratory is also applicable to other types of fields or technical applications and can be used for different forms of training or technical assessment, it is currently used as a support tool to diversify the installed capacity of the laboratory where the number of students exceeds the above capacity, Thereby automating and enhancing the knowledge acquired in this discipline.

Background technique

A worldwide problem these days is that the installed capacity of institutions and/or organizations in technical learning areas (hands-on labs) often exceeds the number of users and/or students, most users and/or students only observe, only a limited Groups are able to take advantage of this facility without taking into account whether this type of resource is geographically utilized by everyone. However, the development of technology has led to the accelerated development of various tools that have been applied to many aspects of life as part of the Internet of Things and its applications and interactions. As part of this trend and the need to provide and/or facilitate the availability of technical resources to everyone, especially those that provide high-quality technical education, due many times to being limited by the large number of students and lack of space to practice, or due to lack of institutional The infrastructure without the practice space to attend these events and promote these tools to anyone who needs them. However, although a large number of aids have been developed, such as online courses, videos and various web tools to facilitate self-learning, it is always necessary to put them into practice, which is why remote laboratories have been developed to enable distance learning platforms (including MOOCs) courses (massive online open courses)) are more effective and impactful. These platforms are seen as solutions needed to improve the quality of traditional systems where multiple users can take lessons on different topics simultaneously, as if it were a face-to-face classroom. The advantage, however, is that everything is remote as activities and tasks are performed and corrected online according to the platform by teachers around the world.

Some of the patents related to the development of this type of system are as follows:

In the invention patent with the patent number WO01/61890A1 and the invention title is the system and method for remotely configuring the test laboratory, a system for controlling and configuring the machines in the laboratory is disclosed, and the system is aimed at the operator, enables them to learn to use the machine without being present at the time. This patent differs from the present invention because in addition to using the same password to work regardless of the machine used, in addition to not having a user registration and control system and an access management system for the laboratory, it uses different tools (such as HTTP protocol and XML-based programming language) to develop the system. This description is closest to the proposed development, but it is not interactive, nor is it real-time nor responsive.

In the invention patent with the patent number US4330833 and the invention title is a method and apparatus for improving digital image processing, a processing method is disclosed, which substantially reduces the amount of computation required for discrete convolution, while providing traditional A good approximation of the result achieved by convolution. This patent is different from the present invention because it never mentions that the user interacts with the images using the platform and the method is completely different from the method explained in this patent.

In the invention patent with the patent number WO2004/059421A2 and the invention title is a system and method for remote access to a virtual laboratory environment, the development of a computer program for an online virtual system education laboratory for remote access is disclosed. A conventional web browser can be used to connect to the lab server from any client system connected to the public network. This file differs from the present invention because it requires a special browser to access the remote laboratory. In this case, it was running from the IE8 browser, leading to infer in this case that the patent refers to a virtual lab rather than a remote access application for a real lab.

In the invention patent with the patent number US20130285477A1 and the invention title is the wireless power supply mechanism of the lab-on-a-chip device, the development of a method capable of remotely powering and controlling the chip is disclosed, which is for the purpose of microfluidics. This patent differs from the present invention because it never uses an interface to interact with the process. Furthermore, it is not suitable for controlling complete electrical and/or electronic circuits integrated by different types of physical components.

In the invention patent with the patent number WO2016/201193A1 and the invention title is a self-operating and transportable remote laboratory system, in addition to disclosing that the system can be moved by a user using it, it also discloses said system capable of automatically analyzing samples . This patent differs from the present invention because the system proposed in this application is always kept in the same place and not used for transportation. In the case of this application the laboratory is operated/controlled by the user, not automated, the results of which depend on the user's activities.

Detailed ways

The details of the features of the remote laboratory system for the study of electrical and electronic circuits are clearly presented in the following description and the accompanying illustrative drawings, by reference indicating the same parts forming the present invention.

The invention described in this patent document consists of a remote laboratory system consisting of three parts: the first part, which includes the technical structure of the different devices, the interconnection of the devices and the part including the part, and the way they interact The second part, which consists of the required platform and means, so that the hardware can interact; and the third part, which describes the interaction method with the user, by which the user can interact with the user according to the determined theme. The different modules interact and can perform predetermined practices for each remote laboratory, in which interaction the third part will be able to generate from its visit, determine the waiting time and allocation time to perform the practice remotely at the physical station, and be able to perform Various practices as determined by the faculty.

The first part basically consists of a computer device (3) with internet access (2) and a set of ports allowing physical interconnection with the stations, the device has a preloaded application developed with the LabVIEW programming tools, but it also physical and logical communication with a unit capable of taking a set of physical signals, converting them into voltages and digitizing them so that they can be processed by a computer, the unit (DAQ) (4) allowing interconnection with the NI ELVIS unit (5), The NI ELVIS unit is a modular engineering education laboratory device that allows the simulation of different devices (such as oscilloscopes, digital multimeters, function generators, variable power supplies, etc.), emphasizing that the unit is located in a workstation (6) in a physical space or in the working module. The aforementioned equipment group constitutes a remote laboratory, and the remote laboratory is interconnected to the Internet (2) through the tcp/ip protocol, wherein the central server (1) is installed with an SQL application and a WEB server. The central server (1) may be located in the same geographical location as other devices, or may be located in a different geographical location. The user is connected via a networked computer (9) to a specific route through which the user can access the platforms of the remote laboratories; it is necessary to mention that these laboratories can change the configuration of the user, replacing the PLC (7) DAQ unit (4), the PLC will control the process (8), which can be elevators, Cartesian robots, processing lines, grading lines, warehouses, automated processes, etc.

The second part, consists of the platform required for the devices and peripherals to interact with each other, it will also provide the interface for the user to operate and visualize the remote lab components, and through this interface to interact with the workstation, the platform basically consists of three Module composition:

1) SQL data management module. This module will be responsible for managing, creating, validating and authenticating user data in different databases created to generate access to remote labs running on the main server.

2) Network or hosted module in the cloud: The application is able to publish and access the Internet, that is, it is the primary means by which remote users interconnect to the platform and interact with workstations. The app is interconnected with the interactive options of the remote lab, providing a visual interface for the interactive options. It should be noted that the app runs on the main server.

3) Modules for remote laboratory control: This is determined by algorithms in LabVIEW and block commands that allow to acquire data from connected circuits and modify their parameters, and is executed in the remote laboratory equipment.

These modules or applications interact when exchanging communications with each other as follows:

1) The SQL application contains a database designed for users to preload their data so that users or entities are subsequently created with their access data, this will allow access to previously preloaded menus of options and tools, and will also highlight that the user will be Validate and authenticate the permissions assigned by the member. Once authenticated, users will be able to enter and select from a schedule and instance menu to use a workstation, which will allow them to book a specific queue to use one of the workstations, while the administrator or instructor chooses to perform a series of preloaded practices . The application has a reservation time, username and password.

2) The LabVIEW module will validate the user's credentials, that is, compare the data specified by the user to enter the practice with the subscription data found in the SQL service database. The interface of the application mainly consists of two parts: the external interface and the internal interface.

a. For the external part, a graphical interface is used, which includes the following parts:

i. Remote IP Address: The part where the IP address representing the person to connect will be displayed.

ii. Remote User: The part that will be displayed representing the username to connect to.

iii. Remote Lab - Server IP Address: represents the server IP address; for each workstation to be connected, the server address is divided into 10 sub-addresses.

iv.DateTfdimePacInt: represents the part that will be displayed for the date and time that the practice will open for the user to connect.

This section and the overall operation of the server include the following (Figure 5):

1) Read the server port that receives the user's permission questions about entering the practice.

2) Once a request is made, the information encapsulated by the TCP/IP protocol is read and decoded to obtain the data it carries. In the first section above, the IP address being transmitted will be obtained and displayed on the front panel of the Remote IP Address section.

3) After obtaining the information encapsulated by the TCP/IP protocol, it is necessary to bring it to the SQL registry using Microsoft SQL Server Management Studio; at this time, verify the reservation so that it is consistent with the request made by the user, and all parameters or Information is converted to string type (such as the date and time that the user will work) and they are placed in the front panel in their respective sections.

4) Once the data is obtained, it will be verified that the person can log into the server to perform the corresponding practice. The process consists of using the user information of the external part of the programming shown earlier and comparing it with the information already registered in the server database about server existence, key password and subscription data. Once this information is verified, a response will be sent to the user in order to access the corresponding practice; if the information provided is incorrect, the user will not be able to access the practice.

b. For the internal part, a graphical interface is also used, where the administrator will observe that all devices are running smoothly and the data presented is the expected data. The interface has the following sections:

i. Concatenation of date, time and user String 1: This section shows the concatenation of registration data, date, time and username from the user request.

ii. User, Password and Station: This section shows the data that the user registers when making a request to be able to use any workstation.

iii. Empty Login, Empty Subscription, Super User: In this section, each status of the work unit is displayed with an LED indicator. Each is illuminated according to the conditions explained below.

· In order to turn on the empty login indicator, the username and password must exist in the database.

· In order to turn on the empty subscription indicator, the subscription made by the user must exist in the database.

· In order to turn on the superuser indicator, only administrators must be logged into their respective accounts.

iv. Subscriptions, Devices, Counting Subscriptions and Counting Devices: This section shows clustered arrays of each of these data as indicators in which information corresponding to each of these sections is displayed, It will be briefly described below.

· In the reservation section, user information is displayed along with the date and time when the reservation was made.

• In the Devices section, the account information of the user operating them is displayed.

• In the Counting Bookings section, the number of bookings made by the user is displayed.

• In the Counting Devices section, a count of the number of times the user has entered the workstation is displayed.

v. Date/Time String: This section shows the concatenation of the date and time registered upon user request.

vi. Concatenated User and Password String 2: This section shows the concatenation of the registered username and password from the user request.

Again, this section consists of two events that will be used to carry out the entire verification process, the operation of each event is explained as follows:

a. In the first event, the data received from the user request is verified through the TCP protocol, and the user and password are confirmed. The information is entered separately as strings, so they must be concatenated so that a single string can enter the database in a way that allows it to perform information management and searching. This must be done from the path or address of the base where the concatenated string is stored, so that the database allows the data to be extracted in the form of a clustered array and displayed in the corresponding cluster.

b. In the second event, the server checks from the same database if there is a reservation for the date and time the request was made. The program captures the time when the request is made and sends it in concatenation with the username and searches for it in the bookings table within the database. The search procedure is very similar to the first event because it uses the same components. The difference is that now it will be searched for booking dates through the platform in another table included in this search. If the information exists and is valid, it will be transmitted as a clustered array to display the information, and empty subscriptions will be enabled to ensure access is already available. Otherwise, it will send an error message because there is no reservation at the requested time. Similarly, this section has a counter indicating how many subscriptions have been made on that workstation.

The operation of these events is typically decomposed through the following steps (Figure 6):

1) The user makes a request to be able to perform the practice, the information being received by the server responsible for performing the search for such information in the database.

2) If the information provided by the user exists in the database, analyze whether a subscription is made; if so, the user will be notified that the practice is accessible and work on it will be started; if there is no subscription, the user will be notified of the message and must subscribe.

3) If the user-provided information does not exist in the database, an error message is sent back.

Once access and subscription are verified, it is passed to a third module consisting of a web server installed on the server and responsible for allowing the publication of the content of the interface platform through which the user must interact in order to work with either of the workstations . A third part is involved here, which is related to the next method or step of accessing the platform and interacting with the physical part. For this physical part, the components published in the web platform are described, which has the following parts:

1) General Information: This section briefly describes the purpose of the laboratory and how globalization and the telecommunications industry can take advantage of allowing laboratory practice to take place at any time and place with access to the Internet.

2) Instructions: This section shows the instructions to be followed in order to be able to use the booking system and work interface.

3) Reservation: In this section, the user has to enter a username and password in order to access the reservation system and reserve one of the stations at a specific time. To use this section, perform the following steps:

a. The username and password provided by the lab instructor or administrator are used to log into the reservation system through the scheduled web route hosting the remote lab.

b. Use the username and password to log into the booking system and check the availability of the timetable in the workstation. Any station and any available time can be selected. The reservation system consists of the following:

a screen where, in addition to the user name, date, time and data for the selected station, a menu with tabs is displayed, where each of the tabs represents the station to be used, in each tab a table is displayed, Where the first column indicates the hour and the first row indicates the day, so that the user can choose the time that best suits them to work using the workstation of the selected tab.

c. Booking or modification can be made 1 hour in advance, once within this range, no further booking or modification can be made.

4) Practices: In this section, links to (in order) access to different practices are provided, as well as brief descriptions of DC and AC circuits.

5) Access interface: This section displays the link to download the executable application. The user can use this link to start working in the corresponding practice, or in a station that has been previously booked; it is important to install the LabVIEW Runtime in order to be able to use the application. The app contains the following sections:

a. Enter User: In this section, the user must enter their access data in order to access the practice.

b. Enter Password: In this section, the user must correctly type the key password in order to access the practice.

c. Station button, from station 1 to station 10: In this section, the user must select a station subscribed in the respective system in order to access the practice.

d. Attempt Indicator: In this section the user is informed of the number of attempts remaining to be able to access the practice in the event of any data mis-entry mentioned above, the user has a maximum of three attempts, if this limit is exceeded, the connection will be is closed and the user will have to connect again.

e. Seconds Indicator: In this section the user is told how many seconds remaining to access the practice, if the counter reaches zero the connection will be closed and they will have to reconnect.

f. Cancel: In this section, the user will be presented with a button by which the user can decide to cancel the subscription to use the workstation.

Once in the application, one of the two interfaces appears to be working on one of the four practices. As mentioned above, specifically, the same circuits were used for Practices 1 and 2, as were Practices 3 and 4. The interface that can be displayed according to the key password used when making the reservation is as follows:

e. In the access interface, the user must type a username and password; the user must use the exact same characters as the username and password created.

6) Faculty: This section shows general data for the faculty who provide the labs to be taught.

It must be emphasized that the user can access the remote laboratory system through an interface that can be accessed from a networked computer with Internet access, where through the access route the user will be able to access a web interface where the user will capture their data, and They will be verified to be able to access different practices previously assigned. To do so, users must first contact the program's faculty and sign up for any of the different options regardless of geographic location. When users have access, they will be able to use an interface that connects with servers that manage different labs, which can be in different physical locations and of different types. These labs are configured with a range of available components (there can be different equipment or workstation configurations). The server will communicate with another device that manages the device, which will allow the different tools and interconnected physical elements (could be DAQ or PLC) to be controlled as needed. For example, when a PLC is used, the control process can be determined by a Cartesian-type robot, a control room, an elevator, a warehouse, a grading line, and the like.

In general, referring to the examples, the remote lab components are as follows:

a. PC Device: The physical device on which applications developed in LabVIEW are hosted, manage, execute, and store information referring to predetermined practice and lab instructions.

b. Workstation: A physical space that can be replicated "n" times as needed, and can be used to apply electronics, automation, and other variant practices. In the case of applied electronics, these workstations use the NI ELVIS system, which is a variety of devices (such as oscilloscopes, digital multimeters, function generators, function generators, Variable Power Supply, Bode Analyzer) modular engineering educational laboratory equipment that allows the interconnection of a printed circuit board with a predetermined circuit and at the same time with a PC device executing a preload algorithm that allows remote The interaction between the user and the workstation that allows different parameters to be changed, measured and applied as if they were in the workstation themselves. These devices allow the practice of different types of electronic devices because the device has the necessary electronic components to be able to change these parameters or practices pre-determined by the instructor; likewise, its implementation and effects can be visualized through the interface. Examples of practices that are carried out on these stations and available in the menu of the remote lab are as follows:

i. Practice 1 - Series and Paralleling of Circuits (DC Interface): This practice focuses on the calculation of voltage, current and resistance values through Ohm's Law and Kirchhoff's Law. So, for this topic, there are three simple series and parallel circuits connected in the workstation.

• This simple circuit consists of a voltage source and a bulb in series to vary the voltage of the first bulb and see its effect through the illumination of the second bulb (Figure ^4a ).

A series circuit is similar to a simple circuit, the only difference is that now instead of one bulb, there are two bulbs that will be connected in series with the voltage source (Figure 4b).

A parallel circuit consists of power supplies connected to two bulbs, the only difference is that now the bulbs are not connected one after the other, but from the same node (Figure 4c).

ii. Practice 2 - Power Balancing in Circuits (DC Interface): This practice uses the exact same connections as Practice 1 (simple, series and parallel). However, this topic focuses on calculating the power of each component and determining that Kirchhoff's laws are also satisfied in terms of power. Since the data is the same, there is no need to make any changes from the previous practice, where the only changes are the concepts to be obtained through mathematical calculations.

iii. Practice 3 - Impedance in AC Circuits (AC Interface): This practice reinforces the theory of AC, how it differs from DC, and determines what the user will observe as the opposite of DC in the signal displayed by the platform. For this topic, two types of series circuits are connected in the workstation, one is purely resistive impedance and the other is resistive and inductive impedance.

• A resistive impedance circuit consists of a voltage source in series with a resistor (Figure 4a).

• Resistive and Inductive The impedance circuit consists of a voltage source in series with the resistor and inductor (Figure 4b).

iv. Practice 4 - Active Power and Apparent Power (AC Interface): In this practice, the exact same circuit is used as in the previous practice, however, the difference will be in the concepts learned and will allow the user to determine these concepts Calculation of results. In this case, the circuit will be used to calculate the power of each circuit component.

v. Practice 5—Efficient Utilization of Energy (AC Interface): In this practice, the concept of power factor is used again, and it is a measure of energy utilization efficiency. In the case of analyzing the results of capacitive and inductive circuits, the practice includes demonstrating through experiments how to correct or improve the power factor so that electrical energy can be used more efficiently.

The efficiency shown by the remote lab has allowed the completion of extended practice, creating usability and comfort for users to practice in the lab. But in addition, the remote laboratory is an indispensable tool for complementing online educational technology (which has so far not fully developed practical parts), thereby extending the scope of education, expanding the impact on the training environment, and using it efficiently facilities and equipment, increasing time and availability, thereby allowing more users to use these facilities. Since they do not need to be physically present in front of the facility, it also expands the dissemination of the technical training program, avoiding the potential congestion and limitations of the facility's capacity at a certain time. It also allows organizations without the resources to have their own facilities, giving them access to a set of technological tools that are difficult to obtain due to cost, and also allows sharing this knowledge with a larger number of users, regardless of their location.
