Description

A pressure test method and device for an electricity consumption information collection system

technical field

The present application relates to the technical field of testing, in particular to a pressure testing method and device for an electricity consumption information collection system.

Background technique

The electricity consumption information collection system, through the collection and analysis of the electricity consumption data of distribution network transformers and end users, realizes electricity consumption monitoring, implementation of ladder pricing, load management, line loss analysis, and finally achieves automatic meter reading, peak shift usage Electricity, electricity inspection, load forecasting and saving electricity cost etc. The establishment of a comprehensive user electricity information collection system requires the construction of a system master station, transmission channels, collection equipment, and electronic energy meters.

The stress test of the power consumption information collection system can be carried out through the stress test tool. There are currently many stress testing tools, such as WebApplication Stress, ApacheBench, Apachejmeter, etc., which can simulate a single terminal to perform stress testing on the collection system by sending requests to the collection system, but it is difficult to comprehensively measure the performance of the collection system. If you need to simulate a large number of terminals for concurrent stress testing, you need to manually start multiple terminals, which is cumbersome and cannot solve the problem of simultaneous triggering of multiple terminals. In practical applications, when the acquisition system receives and processes tens of thousands of terminal requests at the same time, compared with receiving and processing only one request, the pressure on resources such as the acquisition system's receiving buffer, memory, and CPU is different. Usually, a large number of terminals puts greater pressure on the collection system, and the collection system is more likely to reach the bottleneck. The load stress testing tool LoadRunner simulates tens of millions of users to implement concurrent load and real-time performance monitoring to confirm and find problems, but it cannot simulate tens of thousands of terminal request collection systems.

Detailed ways

Referring to FIG. 1 , it is a flow chart of a stress test method for an electricity consumption information collection system provided by the present application. As shown in Figure 1, applied to the electricity consumption information collection system, the method includes:

101. A virtual preset number of terminals.

The power consumption information collection system realizes power consumption monitoring, implementation of ladder pricing, load management, and line loss analysis through the collection and analysis of power consumption data of distribution transformers and end users, and finally achieves automatic meter reading, off-peak power consumption, Electricity checking, load forecasting and saving electricity cost etc. The establishment of a comprehensive user electricity information collection system requires the construction of a system master station, transmission channels, collection equipment, and electronic energy meters.

The power consumption information collection terminal is a device for collecting power consumption information at each information collection point, referred to as the collection terminal. It is a device that can realize the collection of electric energy meter data, data management, two-way transmission of data, and forwarding or execution of control commands. Electricity consumption information collection terminals are divided into special variable collection terminals, centralized meter reading terminals, distributed energy monitoring terminals and other types according to the application places. Terminals include concentrators, special transformer terminals, internet treasures and energy management terminals.

102. Configure a communication protocol of the terminal according to the type of the terminal.

The communication agreement refers to the rules and agreements that must be followed by the two entities to complete the communication or service. Multiple data communication systems in different geographic locations interconnected through communication channels and devices must have a common language in order to enable them to work together to achieve information exchange and resource sharing. What, how, and when to communicate must follow certain mutually acceptable rules. This rule is the communication protocol.

The type of terminal can be used as an identification to distinguish the type of terminal through its different functions in the power consumption information collection system. The types of terminals are different, and the communication protocols used to transmit information in the power consumption information collection system are also different. Therefore, the communication protocols of the terminals need to be configured according to the types of terminals.

103. Trigger the terminal according to the communication protocol.

According to the communication protocol, the terminal is triggered, that is, the virtual terminals of various types are in a virtual working state, and the power consumption information collection system starts to collect information.

104. Use a multi-thread processing mechanism to process terminal trigger events.

Multi-threading refers to the technology that realizes the concurrent execution of multiple threads from software or hardware. Computers with multi-threading capabilities can execute more than one thread at a time due to hardware support, thereby improving overall processing performance. Systems with this capability include symmetric multiprocessors, multicore processors, and chip-level multiprocessing or simultaneous multithreading processors. In a program, these independently running program fragments are called "threads", and the concept of programming using it is called "multithreading". Computers with multi-threading capabilities can execute more than one thread at a time due to hardware support, thereby improving overall processing performance.

The multi-thread processing mechanism is used to process the trigger time of the terminal to realize the concurrent execution of the virtual terminal, so as to conform to the operation status of the terminal and the power consumption information collection system in the actual work, so as to make the obtained stress test results more accurate and reduce the actual terminal and the user. Errors during the operation of the electrical information collection system.

105. Monitor whether the power consumption information collection system is operating normally.

Monitor the operation of the power consumption information collection system, including receiving buffer, memory, CPU operation, etc. If it operates normally, it means that the power consumption information collection system has passed the stress test and can simultaneously collect power consumption information of a preset number of terminals. If it cannot run normally, or the delay is long during the operation, it means that the power consumption information collection system cannot collect the power consumption information of a preset number of terminals at the same time.

This application provides a stress test method for the electricity consumption information collection system, through a virtual preset number of terminals, and then according to the type of the terminal, configure the communication protocol of the terminal, and then trigger the terminal according to the communication protocol, and then adopt a multi-threaded processing mechanism , process the terminal trigger event, and finally monitor whether the power consumption information collection system is running normally. Compared with the prior art, the present application can virtualize tens of thousands or even millions of terminals to perform a force test on the power consumption information collection system. During the test, for the acquisition system, there is no difference between the virtual terminal and the real terminal equipment, and no additional work is required. Through the virtual terminal system, a large number of virtual terminals and virtual data can be provided to assist in the comprehensive testing of power consumption information collection tasks, collection strategies, data collection, data storage, and performance.

Referring to FIG. 2 , it is a flow chart of another stress testing method for an electricity consumption information collection system provided by the present application. As shown in Figure 2, applied to the electricity consumption information collection system, the method includes the following steps:

201. A virtual preset number of terminals.

Terminals include concentrators, special transformer terminals, internet treasures and energy management terminals. Virtual terminals, specifically including a virtual preset number of terminals based on the event-triggered epoll high concurrency model.

epoll is often used to deal with server-side concurrency issues. When more and more people are online on the server side, system resources will be tight and I/O efficiency will become slower and slower. At this time, epoll should be considered. epoll is a poll improved by the Linux kernel to handle a large number of handles, and is a unique I/O function of Linux. epoll is an enhanced version of the multiplexed IO interface select/poll under Linux. Its implementation and usage are quite different from select/poll. epoll completes related tasks through a set of functions instead of one function. The reason why epoll is efficient is that epoll puts the file descriptors that users care about into an event table in the kernel, instead of repeatedly passing in the file descriptor set or event set every time select/poll is called. For example, when an event occurs (such as a read event), epoll does not need to traverse the entire listened descriptor set, but only traverses the descriptor set that is asynchronously awakened by the kernel IO event and added to the ready queue. epoll has two working modes, LT (level triggered): level triggered and ET (edge-triggered): edge triggered. LT is the trigger method used by select/poll, which is relatively inefficient; while ET is the high-speed working method of epoll.

There are three functions in epoll. When the server is epoll, the steps are as follows: call the epoll_create function to create an event table in the Linux kernel; then add the file descriptor (listening socket) to the created event table; in the main loop , call epoll_wait to wait for the ready file descriptor set to be returned; process the ready event set separately. The above server-side epoll steps provide a basis for realizing the stress test of the user electricity consumption information collection system.

202. Configure a communication protocol of the terminal according to the type of the terminal.

The communication agreement refers to the rules and agreements that must be followed by the two entities to complete the communication or service. Multiple data communication systems in different geographic locations interconnected through communication channels and devices must have a common language in order to enable them to work together to achieve information exchange and resource sharing. What, how, and when to communicate must follow certain mutually acceptable rules. This rule is the communication protocol.

203. Acquire the protocol type of the communication protocol.

The communication agreement refers to the rules and agreements that must be followed by the two entities to complete the communication or service. The protocol defines the format used by the data unit, the information and meaning that the information unit should contain, the connection method, and the timing of sending and receiving information, so as to ensure that the data in the network is transmitted to a certain place smoothly. The communication protocol is mainly composed of the following three elements: Grammar: that is, how to communicate, including data format, encoding and signal level. Semantics: Communication content, including data content, meaning, and control information. Timing rules: When to communicate, specify the order of communication, rate matching and sequencing.

Commonly used communication protocols mainly include three protocols: TCP/IP, NETBEUI and IPX/SPX, and each protocol has its applicable application environment. It can be known that different terminals use not exactly the same communication protocol. Obtain the protocol type of the communication protocol configured by the virtual terminal, so as to carry different data information through different communication protocols.

204. According to the protocol type, the power data of the virtual terminal.

The electric energy data includes current, voltage, power, power angle, etc. In this embodiment of the present application, there is no limitation on the specific objects included in the electric energy data.

Since the terminal is a virtual terminal, the power data is also virtual in nature, and is obtained virtually according to the power data that can be carried by the protocol type.

205. Configure trigger parameters of the terminal according to the communication protocol.

Trigger parameters include energy data. According to the communication protocol and specific protocol rules, configure the power data of the terminal.

206. Trigger the terminal according to the trigger parameter.

The trigger terminal, that is, trigger the virtual terminal, that is, the power consumption information collection system, collects the power consumption information of the virtual terminal when the virtual terminals are triggered at the same time.

207. Use a multi-thread processing mechanism to process the terminal trigger event.

In computer programming, a basic concept is to control multiple tasks at the same time. Many programming problems require that the program stop what it is doing, handle some other problem, and then return to the main process. This can be achieved in a number of ways. At the beginning, programmers who mastered the low-level language of the machine wrote some "interrupt service routines", and the suspension of the main process was realized through hardware-level interrupts. While this is a useful approach, the resulting programs are difficult to port, creating another class of costly problems. Interrupts are necessary for those tasks with strong real-time nature. But for many other problems, it is only required to divide the problem into independent program fragments, so that the whole program can respond to the user's request more quickly.

Multithreading is to complete multiple tasks simultaneously, not to improve operating efficiency, but to improve resource usage efficiency to improve system efficiency. Threads are implemented when multiple tasks need to be done at the same time. The multi-thread processing mechanism can efficiently complete the collection of terminal power consumption information.

208. Monitor whether the power consumption information collection system is running normally.

This step is similar to the method described in step 105 shown in FIG. 1 , and will not be repeated here.

209. If the power consumption information collection system operates normally, increase the preset quantity according to the preset rules.

If the power consumption information collection system can still operate normally, this test did not test the maximum pressure that the power consumption information collection system can withstand. In order to accurately measure the pressure-bearing capacity of the power consumption information collection system, it is also necessary to increase the number of virtual terminals, that is, increase the number of presets. For increasing the number of presets, the preset step size can be increased according to the preset number, and the system operation status can also be collected according to the monitored power consumption information. Increase the number of terminals that can still be expected to withstand.

210. If the power consumption information collection system is not operating normally, reduce the preset quantity according to the preset rules.

Similar to step 209, if the power consumption information collection system cannot operate normally, the virtual preset number of terminals in this test is not necessarily the critical number of power consumption information collection systems under pressure. In order to accurately measure the power consumption information collection system The pressure-bearing capacity also needs to build the number of virtual terminals, that is, reduce the number of presets. For the reduction of the preset quantity, the preset step size can be reduced according to the preset step size, and the preset number can also be directly reduced according to the monitored power consumption information collection system operating status, the estimated number of terminals that can be tolerated, and the preset number To the expected number of terminals that can be supported.

211. According to increase/decrease preset quantity, virtual terminal.

According to the change of the preset quantity in step 209 or step 210, the virtual terminal is re-executed, and the stress test of the power consumption information collection system is performed again. Until the critical terminal quantity range of the power consumption information collection system is tested.

This application provides a stress test method for the electricity consumption information collection system, through a virtual preset number of terminals, and then according to the type of the terminal, configure the communication protocol of the terminal, and then trigger the terminal according to the communication protocol, and then adopt a multi-threaded processing mechanism , process the terminal trigger event, and finally monitor whether the power consumption information collection system is running normally. Compared with the prior art, the present application can virtualize tens of thousands or even millions of terminals to perform a force test on the power consumption information collection system. During the test, for the acquisition system, there is no difference between the virtual terminal and the real terminal equipment, and no additional work is required. Through the virtual terminal system, a large number of virtual terminals and virtual data can be provided to assist in the comprehensive testing of power consumption information collection tasks, collection strategies, data collection, data storage, and performance.
