Embodiment 1

[0028] Example 1, reference Figure 1 to 3 As shown, a relay panel universal test device, comprising: an external connection unit, a general IO interface coupled to a panel of the test relay;

[0029] The input and output unit is connected to the external connection unit, and the IO element module includes a power source for driving a first driving circuit, a second drive circuit, and a first driving circuit, a second drive circuit, and a use The back-inspection circuit detected by the test relay is detected, the first driving circuit connecting the first output switch, the second drive circuit to the second output switch;

[0030] The control unit is configured to control the input and output unit, and determine the status of the measured relay;

[0031] Human-machine interaction unit, used to input the measured relay board type, and select the corresponding test method and send to the control unit according to the relay connection of the relay board type.

[0032] The communicati...

Embodiment 2

[0038] Embodiment 2, a relay board test method, including the following steps:

[0039] The test relay is connected to the test device by the general IO interface of the external connection unit;

[0040] Through the humanoid interaction unit, input the measured relay board type, obtain the corresponding relay connection mode according to the database, according to the interface of the relay board, select the corresponding test mode (different relays, the output interface is different. The output interface is to be "high or low level or configured to input state").

[0041] The control unit is connected to the power source through the K3 of the IO unit 2 of the drive circuit, and the IO2 is connected to the power source.

[0042] The control unit is connected to the K6 of the IO unit 3 of the drive circuit, and the IO3 is connected to the ground, and the output drives low signal.

[0043] After the above two operations, the relay should be in an absorbed state.

[0044] The contro...

Abstract

The invention discloses a general test device and a test method for a relay single board, comprising: an external connection unit provided with a general IO interface connected with the relay single board to be tested; an input and output unit connected with the external connection unit and provided with a plurality of The IO unit module, the IO unit module includes a power supply, a first drive circuit for driving the relay under test that can be driven high or low, a second drive circuit, and a checkback circuit for detecting the contact state of the relay under test, so The first driving circuit is connected to the first output switch, and the second driving circuit is connected to the second output switch; the control unit is used to control the input and output unit and judge the state of the relay under test; the human-computer interaction unit is used to input the measured relay The relay board type, and match the relay connection mode according to the relay board type, select the corresponding test method and send it to the control unit; the communication unit is used for the communication connection between the human-computer interaction unit and the control unit. The present invention can adapt to different relay single boards.

Description

Technical field [0001] The present invention relates to the field of electrical control technologies, and specific relate technologies involve relay testing techniques. Background technique [0002] Single boards of mounting structures are usually applied to industrial control systems, rail transit control systems, instrumentation and other control systems. In these control systems, the relay will be used in large quantities, and these relays typically use the PCB board installation mode for easy installation. The relay board described herein refers to a plate-type relay board that is used as a board-mounted mounting structure. [0003] Board-type relay single board use is very wide, these relays are available in production, during use, need to use test tool test relay panels working properly. Because the relay board is used very widely, even in the same system, it will also have different causes such as the external connector signal. There will be different relay boards, and the...
