A test method for computer peripheral equipment interface

technical field

The invention relates to a method for testing computer peripheral equipment interfaces, in particular to a method for testing 1394 equipment.

Background technique

With the continuous innovation and development of computer peripheral equipment interfaces, the capacity and time requirements for data transmission between peripheral equipment and computers continue to increase, and a new peripheral equipment interface 1394 has emerged as the times require. 1394 was established by Apple as the IEEE-1394 standard in 1995 by the IEEE Association. IEEE provides a new common interface between computer equipment and household electrical appliances, which has the characteristics of high transmission rate and plug-and-play. It is very suitable for large-capacity transmission of various existing multimedia image files, voice and other data. Moreover, when installing 1394 equipment in a 1394 environment and a computer, there is no need to shut down the machine, and there is no need to restart the machine after inserting the equipment, and it can be recognized and used by the computer immediately. In addition, IEEE1394 has a point-to-point transmission mode, and also has the characteristics of high speed and timeliness.

Due to its excellent performance, many existing desktop computers and notebook computers are equipped with 1394 interfaces. As we all know, computer manufacturers need to conduct an overall test on the computer when the product is shipped, which includes testing whether the 1394 adapter is working properly. According to the concept of the 1394 standard design, at least one device with a 1394 interface (such as a digital camera, etc.) needs to be connected to the test machine for testing, and then data (sound files, video files) are transmitted.

However, in the test of the computer manufacturer, it is impossible to completely follow the design concept of the 1394 interface, and use a specific device including a 1394 interface, such as a digital camera, to test the pros and cons of the 1394 adapter of the computer. Cost, and its test efficiency cannot be guaranteed, so it is not suitable for large-scale production.

At this time, a simple and efficient method for testing 1394 devices is needed to solve the above problems.

Contents of the invention

In view of this, the present invention proposes a kind of method of testing 1394 equipment in order to solve the above problem, and its purpose is to form 1394 network by setting up a test server and the equipment under test that comprises 1394 adapter, transmit file or data on this network, The data transmission between the 1394 adapter of the computer and the 1394 interface of the peripheral equipment is simulated, so as to complete the test of the 1394 adapter.

The present invention proposes a method for testing 1394 equipment. The method includes the following steps. First, it is determined that the 1394 adapter drivers of a plurality of equipment to be tested are installed successfully, and then the equipment to be tested is connected to the test server through a 1394 cable, and the adapter is allocated address, start a plurality of TCP/IP services at the server, set the port and the maximum number of connections on the port, and establish 1394 network connections between the test server and the device under test through the address and port, wherein the 1394 network connection steps also include: The method comprises the following steps: the device under test obtains the port number assigned by the server to its adapter; creates a socket according to the port number and binds the address of the adapter; sends a connection request to the server through the socket; to the connection request sent by the adapter; and establish a 1394 network connection between the server and the device under test adapter, and finally carry out the transmission test of the adapter through the network connection, wherein the steps of the transmission test also include the following steps: the server reads The device under test is taken to transmit test data; the data is sent back to the adapter; and the adapter checks the returned data.

Compared with the existing method, the test method of the 1394 adapter provided by the present invention can complete the test without providing additional hardware, and there are few human-operated parts in the test process, thereby avoiding the disadvantages of the existing test technology. Large-scale testing has the shortcomings of high cost and low efficiency, which improves the efficiency and accuracy of testing, reduces testing costs, and provides an effective guarantee for large-scale testing.

The detailed content and method of the present invention are described as follows in conjunction with the accompanying drawings.

Detailed ways

The present invention is described in detail below in conjunction with accompanying drawing:

As shown in Figure 1, this figure is the overall flow chart of the method for testing 1394 equipment of the present invention, described as follows:

First determine that the 1394 adapter drivers of a plurality of devices under test are successfully installed (step 110); then connect the device under test and the test server (step 120) by 1394 cables; assign addresses for this adapter (step 130); A plurality of TCP/IP services, setting port and port maximum number of connections (step 140); Set up 1394 network connections (step 150) between this test server and the device under test by this address and port; Finally carry out by this network connection Transmission test of the adapter (step 160).

Wherein, the address may be the virtual MAC address of the 1394 adapter of the client to be tested, or the virtual MAC address of the 1394 adapter of the client to be tested and its assigned IP address. According to the specific test situation to decide.

Multiple TCP/IP services are started on the server, and each service needs to occupy a specific port, so the port is in one-to-one correspondence with the multiple started TCP/IP services.

Please refer to Fig. 2, this figure is the flow chart that the present invention proposes to set up the 1394 network connection between this test server and the device under test, and description is as follows:

First this equipment under test obtains the port number (step 210) that server distributes for its adapter; Then according to this port number, create socket (Socket), and bind the address (step 220) of this adapter; Through this socket ( Socket) sends a connection request to the server (step 230); the server determines to receive the connection request sent by the adapter (step 240); finally establishes a 1394 network connection between the server and the device under test adapter (step 250).

Wherein, the port number assigned by the server to the adapter of the device under test is an I/O transmission channel between 1394 adapters.

Multiple ports are opened on the server, and each port represents a specific service and is connected to a different adapter, so the 1394 network connection is actually a connection between a certain port of the server and the adapter of the device under test.

After the server assigns an address to the adapter of the device under test and starts the TCP/IP service, in order to receive the connection request sent by the adapter in time, it will listen to all the ports established by the server in a loop to receive Information from the DUT adapter.

Please refer to Fig. 3 to illustrate, this figure is the flow chart that the present invention proposes to carry out the transmission test of this adapter by this network connection, description is as follows:

First, the server reads the test data from the device under test (step 310); then sends the data back to the adapter (step 320); finally, the adapter checks the returned data (step 330).

Among them, the server reads the test data transmitted by the device under test by creating a management subroutine for each port on the server and managing the corresponding ports. This subroutine is used to control the amount of data transmitted and the speed of transmission. , as a parameter index to measure the performance of 1394 interfaces and adapters.

In the actual test, take testing a computer with 1394 interface as an example, you first need to install the driver of the 1394 adapter for the computer, and then use the IEEE1394 cable to connect the 1394 interface of the computer to the 1394 interface of the test server. IEEE1394 cables generally consist of 4 or 6 wires (two pairs of twisted-pair wires for data transmission and a pair of power wires for powering external devices). At this time, the 1394 adapter of the service and the computer will be virtualized as a network device, and a MAC address will be assigned to each virtualized 1394 adapter. Then assign IP addresses to two 1394 adapters (Adapter), and establish a network connection, so that a 1394 network is established between the test computer and the test server.

The process of connecting the server to 1394, and IP address assignment is completed by 1394 ARP (Address Resolution Protocol, Address Translation Protocol, Address Resolution Protocol) and MCAP (MulticastChannel Allocation Protocol, Multicast Channel Allocation Protocol), using IP for data packet transmission . Reduce the dependence on 1394 physical layer, link layer protocols and system guidelines.

Next, you can use the 1394 network, TCP/IP service and WinSock technology to transmit data between the server and the computer to be tested so as to complete the test of the 1394 adapter of the computer to be tested.

Start multiple TCP/IP services on the server, each service corresponds to a specific port, and set the maximum number of connections on the port. Then the computer to be tested will obtain the port number assigned to it by the server through the general channel of 1394. After obtaining the port number, create a socket (Socket) and bind the assigned IP address. Send a connection request to the server. The server will constantly listen to the information received by the established port, confirm that it has received the request sent by the computer adapter to be tested, and start to connect with it. After the server is successfully connected to the computer to be tested, the server will establish a subroutine for the connection to manage the data transmission between them, and then the 1394 adapter of the computer to be tested starts to send test data to the server; the server reads the test After the data is sent back to the 1394 adapter of the computer to be tested, the adapter will verify it after reading the data returned from the server.

At this point, a data transmission is completed. This process is repeated continuously, and the purpose of testing the 1394 adapter of the computer to be tested can be achieved.

Further consideration, if each machine is tested, the 1394 network needs to be reconfigured, which will inevitably increase the test time. The 1394 interface is the same as the USB1.1 or 2.0 interface, and it is also a bus control interface. We can use the current 1394 expansion technology to select a machine as a test server, install 1394HUB or expansion cascading devices on it, and test in this way The server can provide multiple 1394 interfaces, and connect multiple computers under test with IEEE 1394 cables for simultaneous communication. Because IEEE1394 devices support hot plugging, adding or removing devices to the IEEE1394 network at any time during the test process, there is no need to worry about data transmission or any reconfiguration, and the system can automatically adjust according to the changing environment. When a virtual network is established between multiple 1394 adapters, we can use TCP/IP services, WinSock, a mature technology, and client/server (Client/Server) architecture for data transmission testing. The process is the same as testing a computer's 1394 adapter.

The test server can manage multiple tested 1394 adapters connected to it, and record the current test status of each 1394 adapter. Each 1394 adapter can send data to the server at the same time; the server can process the data sent from each 1394 adapter and check the validity of the data. It is then responsible for sending the data back to the client (Client). During the communication process, the server (server) can control the amount of data transmitted and the speed of transmission, which can be used as parameters to measure the performance of the 1394 interface and adapter.

Each 1394 adapter runs a unified test program (script). Responsible for configuring and managing the IP of the local 1394 connection, sending test data (files) to the server, receiving test data (files) from the server, verifying test data (files) and so on.

In addition, since the 1394 interface supports common network protocols such as NETBEUI and IPX/SPX at the same time, in a small 1394 LAN, the NETBEUI protocol can be used to test the 1394 port due to its advantages of simple operation, high efficiency and quickness. Because the NETBEUI protocol lacks routing and network layer addressing functions, it does not need additional network addresses and network layer headers and tails. Two machines in the same 1394 network, because they are in a simple network environment, do not need routing control and network identification. The application layer can use their respective machine names as the identification of the connection, and the network layer uses the data link through the NETBEUI protocol. Layer layer Media Access Control (MAC) address for communication. Its test process is the same as that using the TCP/IP protocol.

The example mentioned above is an example of using the C/S architecture for data transmission settings, and this architecture can also be used for the test of transferring files. Because of the communication speed of 1394, the performance is stronger than that of the Ethernet card, and it is not affected by the resources occupied by other connections in the LAN, which improves the test efficiency.

Several shared folders were assigned to each 1394 adapter during the server test. On each tested machine where the 1394 adapter is installed, use a shared file folder on the adapter side as its network image drive. Each client (machine to be tested) performs file system operations on the shared area of the server through the established 1394 connection, including read-only test (Read Test operation), write test (Write Test operation) and read-write test (Read/Write Test operation).

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the implementation scope of the present invention; all equivalent changes and modifications made in accordance with the specification and claims are covered by the patent scope of the present invention.
