Description

Technical Field

[0001] This utility model relates to the field of solid-state display box testing technology, and in particular to a solid-state display box testing circuit and testing device. Background Technology

[0002] The automatic hump yard display system is an auxiliary system used in railway hump marshalling yards to automatically monitor and present information related to hump operations in real time. Its core function is to automatically collect information on the running 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 working environment through sensors and detection equipment. This data is then converted into visual information in real time (such as screen displays and indicator light statuses) and presented intuitively to hump yard operators (such as dispatchers and shift workers). The main purpose of this system is to provide operators with real-time and accurate operational dynamics, assisting them in efficiently directing vehicle shunting and adjusting equipment actions, thereby ensuring the safety and efficiency of hump marshalling operations.

[0003] Currently, with the rapid development of railway electronic products, the application of solid-state indicator boxes in hump yards is increasing year by year. Solid-state indicator boxes are used to indicate whether the outdoor speed reducers or parking relays of the automatic hump yard indicator system are activated.

[0004] To ensure the quality of solid-state display boxes before they leave the factory, they need to be tested. Specifically, the test needs to be conducted to determine whether the display box has the function of indicating relay closure and whether it can correctly indicate the closure status of the relay, thereby ensuring the quality of the solid-state display boxes before they leave the factory.

[0005] With the continuous increase in the production of solid-state display boxes, the original testing methods are inefficient and cannot meet the growing demand for solid-state display boxes, which has affected the overall production progress of solid-state display boxes.

[0012] The other end of push-button switches K5 to K6 is connected to the solid-state display box and is 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 both the solid-state display box and indicator light H1;

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

[0180] To better understand the technical solution of this utility model, the working principle of the solid-state display box 100 itself is explained below.

[0181] The working principle of a solid-state indicator box is as follows: a solid-state indicator box is a type of indicator box that uses the closing and opening of a solid-state relay to indicate the closing of a relay in an outdoor speed reducer or parking device;

[0182] 1. When the push-button switch K1 is closed, thus providing DC power DC1 positive power to the first and second input terminals (pin G11) of the solid-state display box, it can simulate the external hump automatic control system supplying power to the first and second input terminals (pin G11) of the solid-state display box. When the first and second input terminals are energized, the coils of solid-state relays KM11 and KM12 (specifically, pins J14 and J13 at both ends of the coil) are energized, thereby closing the contacts of solid-state relays KM11 and KM12 (specifically, pins J5 and J9).

[0183] At this time, when the push-button switch K5 is closed, the first output terminal (pin G21) of the solid-state display box is connected to the positive DC power supply DC2, which energizes the coil of relay KM1 (specifically pins J14 and J13 at both ends of the coil), thereby indicating that the contacts (specifically pins J5 and J9) of relay KM1 in the first channel (circuit) are closed.

[0184] When the push-button switch K6 is closed, the fifth output terminal (pin G23) of the solid-state display box is connected to the positive DC power supply DC2, which energizes the coil of relay KM5 (specifically pins J14 and J13 at both ends of the coil), thereby indicating that the contacts of relay KM5 in the fifth (circuit) are closed (specifically pins J5 and J9).

[0185] 2. When the push-button switch K2 is closed, thus providing DC power DC1 positive power to the 3rd and 4th input terminals (pin G31) of the solid-state display box, it can simulate the external hump automatic control system supplying power to the 3rd and 4th input terminals (pin G31) of the solid-state display box. When the 3rd and 4th input terminals are energized, the coils of solid-state relays KM13 and KM14 (specifically, pins J14 and J13 at both ends of the coil) are energized, thereby closing the contacts of solid-state relays KM13 and KM14 (specifically, pins J5 and J9).

[0186] At this time, when the push-button switch K5 is closed, the second output terminal (pin G22) of the solid-state display box is connected to the positive DC power supply DC2, which energizes the coil of relay KM2 (specifically pins J14 and J13 at both ends of the coil), thereby indicating that the contacts (specifically pins J5 and J9) of the relay KM2 in the second (circuit) are closed.

[0187] When the push-button switch K6 is closed, the sixth output terminal (pin G43) of the solid-state display box is connected to the positive DC power supply DC2, which energizes the coil of relay KM6 (specifically pins J14 and J13 at both ends of the coil), thereby indicating that the contacts of relay KM6 (specifically pins J5 and J9) of the sixth (circuit) are closed.

[0188] 3. When the push-button switch K3 is closed, thus providing DC power DC1 positive power to the 5th and 6th input terminals (pin G51) of the solid-state display box, it can simulate the external hump automatic control system supplying power to the 5th and 6th input terminals (pin G51) of the solid-state display box. When the 5th and 6th input terminals are energized, the coils of solid-state relays KM15 and KM16 (specifically, pins J14 and J13 at both ends of the coil) are energized, thereby closing the contacts of solid-state relays KM15 and KM16 (specifically, pins J5 and J9).

[0189] At this time, when the push-button switch K5 is closed, the third output terminal (pin G41) of the solid-state display box is connected to the positive DC power supply DC2, which energizes the coil of relay KM3 (specifically pins J14 and J13 at both ends of the coil), thereby indicating that the contacts (specifically pins J5 and J9) of relay KM3 in the third (circuit) are closed.

[0190] When the push-button switch K6 is closed, the 7th output terminal (pin G61) of the solid-state display box is connected to the positive DC power supply DC2, which energizes the coil of relay KM7 (specifically pins J14 and J13 at both ends of the coil), thereby indicating that the contacts of relay KM7 in the 7th (circuit) (specifically pins J5 and J9) are closed.

[0191] 4. When the push-button switch K4 is closed, thus providing DC power DC1 positive power to the 7th and 8th input terminals (pin G51) of the solid-state display box, it can simulate the external hump automatic control system supplying power to the 7th and 8th input terminals (pin G71) of the solid-state display box. When the 7th and 8th input terminals are energized, the coils of solid-state relays KM17 and KM18 (specifically, pins J14 and J13 at both ends of the coil) are energized, thereby closing the contacts of solid-state relays KM17 and KM18 (specifically, pins J5 and J9).

[0192] At this time, when the push-button switch K5 is closed, the fourth output terminal (pin G42) of the solid-state display box is connected to the positive DC power supply DC2, which energizes the coil of relay KM4 (specifically pins J14 and J13 at both ends of the coil), thereby indicating that the contacts (specifically pins J5 and J9) of the fourth (circuit) relay KM4 are closed.

[0193] When the push-button switch K6 is closed, the 8th output terminal (pin G62) of the solid-state display box is connected to the positive DC power supply DC2, which energizes the coil of relay KM8 (specifically pins J14 and J13 at both ends of the coil), thereby indicating that the contacts of relay KM8 in the 8th (circuit) (specifically pins J5 and J9) are closed.

The positive terminal of the DC power supply DC1 is connected to pin G11 of the solid-state display box 100, and the first display terminal of the solid-state display box 100 is activated. Then, close the circuit breaker K5, which indicates that the first output terminal (i.e., pin G21) of the solid-state display box 100 outputs positive DC power DC2. When the coil between pins J13 and J14 of the relay KM1 is energized, the other pins J5 and J9 are closed and connected.

[0216] Then, the positive and negative currents of the DC power supply DC2 are connected to pins Z1 and Z2 of the indicator light H1, causing the indicator light H1 to light up. This ultimately achieves the purpose of testing whether the first output terminal (i.e., pin G21) of the solid-state indicator box 100 has the function of indicating that the relay is closed.
