Description

Technical Field

[0001] The present invention relates to the technical field of solid-state display box testing, in particular to a solid-state display box testing circuit and a testing device. Background Art

[0002] The hump automatic display system is an auxiliary system used in railway hump marshalling yards to automatically monitor and present information related to the hump operation process in real time. Its core function is to automatically collect information such as the operating status of shunting vehicles (such as position and speed), the working status of key hump equipment (such as outdoor speed reducers and parking devices), and the operating environment through technical means such as sensors and detection equipment. It then converts this data into visual information (such as screen displays and indicator light status) in real time and presents it intuitively to hump operators (such as dispatchers and duty officers). The main function of this system is to provide operators with real-time and accurate operation dynamics, assisting them in efficiently directing vehicle shunting and adjusting equipment operations, thereby ensuring the safety and efficiency of hump marshalling operations.

[0003] With the rapid development of railway electronic products, the application of solid-state display boxes in hump yards is increasing year by year. Solid-state display boxes are used to indicate whether the outdoor speed reducer or parking relay of the hump automatic indication system is operating.

[0004] In order to ensure the factory quality of the solid-state display box, it needs to be tested before leaving the factory. Specifically, it is necessary to test whether the display box has the function of indicating the closure of the relay and whether it can correctly indicate the closure status of the relay, so as to ensure the factory quality of the solid-state display box.

[0005] As the production of solid-state display boxes continues to increase, the original testing method is inefficient and cannot meet the demand for the growing number of solid-state display boxes, which has affected the overall production progress of solid-state display boxes.

[0006] Therefore, there is an urgent need to develop a technology that can solve the above technical problems. Summary of the Invention

[0010] The DC power supply DC2 is connected to the solid-state display box and one end of the push button switches K5-K6 respectively;

[0011] The other ends of the push button switches K1 to K4 are connected to the solid-state display box and are used to control the electrical connection between the solid-state display box and the DC power supply DC1;

[0012] The other ends of the button switches K5-K6 are connected to the solid-state display box and are used to control the electrical connection between the solid-state display box and the DC power supply DC2;

[0013] Relay KM1 is connected to one end of the solid-state display box and indicator light H1 respectively;

[0014] Relay KM2 is connected to one end of the solid-state display box and indicator light H2 respectively;

[0015] Relay KM3 is connected to one end of the solid-state display box and indicator light H3 respectively;

[0016] Relay KM4 is connected to one end of the solid-state display box and indicator light H4 respectively;
