Problems solved by technology

[0005] Of course, using an independent automatic test program can detect some abnormal problems in the running process, but there are also many inconveniences:
[0006] 1. It brings additional processes to production, and the program needs to be re-downloaded after the test is completed
[0007] 2. When the peripherals are changed or the test method is upgraded, the automatic test program needs to be upgraded, which brings trouble to the management
[0008] 3. In the normal operation of the equipment, since it is generally not allowed to modify the running program during regular testing, only the self-test function of the protected application program can be used for testing. Based on security considerations, these tests are generally better than special automatic testing programs. Few functions, or not thorough enough

Embodiment Construction

[0030] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings of the specification.

[0031] Attached figure 1 It is the flow chart of the method of the present invention. The single board to be tested is connected through the backplane CAN bus, or can be networked through an Ethernet switch, and the server (or test background) sends the test program data packet on the LAN or CAN network.

[0032] A hook function is added to the board to be tested. This function can perform specific actions after receiving a certain packet message and verifying it correctly.

[0033] When the server (or the test background) has a request to transmit a test file, the single board to be tested extracts the executable code of the test program from the message data packet and stores it in the designated RAM area.

[0034] When the test program is successfully transmitted, it will send a transmission success message to close th...

Abstract

The invention discloses a method for automatically testing a single board of a protective relay device. According to the method, a hook function is added in a program on a single board plug-in unit; and when a test program data packet is sent, the hook function can acquire the corresponding data packet and store the data packet in an executable RAM region. An application program can automatically jump to the RAM region to execute the test program and test whether the functions of the single board are normal or not; and after the single board is powered down and powered up again, the application program cleans up the RAM region data packet after self-checking the RAM, and the test program is automatically deleted. The method disclosed by the invention can bring conveniences for testing the single board of the protective relay device, reduce the single board debugging steps, and improve the production efficiency.

Description

Technical field [0001] The invention belongs to the field of power electronics and relay protection of power systems, and specifically relates to a method for testing a single board of a relay protection device, and is a safe automatic testing method for a single board of a relay protection device. Background technique [0002] During the production and use of relay protection and other devices, testing is often required. For example, after the production of the single board (the single board here refers to the electronic component plug-in that can independently complete a certain function after the printed board is installed and welded with the corresponding electronic components), the single board should be tested to test whether the hardware is intact ; During the production process of the device, the device hardware should be tested to see if the test function is complete and whether there is a drop in performance indicators; during the use process, the device should be regul...
