Currently, there is no offline testing platform or environment for intermediate power supply boards, and testing of these boards mainly relies on on-site testing, requiring the boards to be installed in the field.

[0003] During the testing process, maintenance personnel need to bring the repaired intermediate power supply board to the site and rely on the cooperation of operations personnel to conduct the tests. The testing time is relatively long, usually 3 to 4 hours, and reliability tests, such as burn-in tests, cannot be performed. At the same time, on-site testing requires turning on the entire equipment, which poses a risk of damaging other equipment and causing safety impacts on the on-site equipment.

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] In urban rail transit, intermediate power supply boards are installed in long sections of the track circuit. The intermediate power supply boards receive route direction information from the trackside LZB (trackside equipment of the automatic train control system) and section occupancy information from relevant boards at the track circuit receiving end. The intermediate power supply boards perform logical operations based on these input information (section occupancy information) and output the processed signals to the direction conversion board to control the working state of the direction conversion board.

[0022] To avoid weakening the signal in the long section, the receiver board is moved to the middle of the long section when the train enters the beginning of the long section, and then moved to the end of the long section when the train enters the middle of the long section. The long section is 390m long.

[0023] The specific workflow between the intermediate power supply board and the direction conversion board is as follows: when the train head enters a long section of the track circuit and approaches the intermediate transmitting end, the receiving board moves its head from the middle to the tail end in the direction of train travel. The direction conversion board, under the control of the intermediate power supply board, switches between the transmitting and receiving cables by controlling the operation of internal relays, ensuring that the transmitting direction of the track circuit always faces the direction of train travel, thus guaranteeing that the train can continuously receive trackside ATP messages.

[0024] See Figure 1-2 As shown, this utility model provides a test device for an intermediate power supply board. The intermediate power supply board 4 includes an indicator light unit, which is connected to a direction conversion board 5. The test device includes a control module 1, a power supply module 2, and a display module 3. The intermediate power supply board 4 is connected to the control module 1 and the power supply module 2, and the control module 1 is connected to the display module 3.

[0025] Control module 1 generates control signals, intermediate power supply board 4 operates according to the control signals, control module 1 collects the working status of indicator unit, and generates test results that are fed back to display module 3 based on the working status.

[0026] In one embodiment of the present invention, the control module 1 includes a control chip 101 and a board unit 102; the control chip 101 is connected to the board unit 102 and the display module 3, and the board unit 102 is connected to the intermediate power supply board 4. The board unit 102 includes a first receiving board 1021, a first adapter port 1022, a second receiving board 1023, a second adapter port 1024, a message board 1025, and a third adapter port 1026. The first receiving board 1021 is connected to the first adapter port 1022 and the control chip 101, and the first adapter port 1022 is connected to the intermediate power supply board 4. The second receiving board 1023 is connected to the second adapter port 1024 and the control chip 101, and the second adapter port 1024 is connected to the intermediate power supply board 4. The message board 1025 is connected to the third adapter port 1026 and the control chip 101, and the third adapter port 1026 is connected to the intermediate power supply board 4. The first adapter port 1022, the second adapter port 1024, and the third adapter port 1026 realize the physical connection between the intermediate power supply board 4 and different boards, thereby ensuring the signal transmission between the test device and the intermediate power supply board 4.

[0027] In one embodiment of this utility model, the intermediate power supply board 4 includes a digital circuit, which is connected to the indicator light unit, the first adapter port 1022, the second adapter port 1024, and the third adapter port 1026.

[0028] See Figure 2 As shown, the control signals generated by control module 1 include high and low level signals R1 emitted by the first receiving board 1021, high and low level signals R2 emitted by the second receiving board 1023, and high and low level signals FR emitted by the trackside LZB (trackside ATP message). Based on the signals R1, R2, and FR output by board unit 102 to the intermediate feeder board 4, the operating direction, occupancy, or idle status of the train are controlled. The functions of signals R1, R2, and FR are as follows:

[0029] When signal R1 is high (H), receiver 1 of intermediate feed board 4 is in an idle state; when it is low (L), receiver 1 of intermediate feed board 4 is in a occupied state.

[0030] When signal R2 is high (H), receiver 2 of intermediate feed board 4 is idle; when it is low (L), receiver 2 of intermediate feed board 4 is occupied.

[0031] When the signal FR is high (H), the operating direction of the long section where the intermediate power supply board 4 is located is the G operating direction; when it is low (L), the operating direction of the long section where the intermediate power supply board 4 is located is the A operating direction.

[0032] The indicator light unit includes indicator lights FG, FA, S1, and S2. The direction conversion board 5 connected to the intermediate power supply board 4 includes a first direction conversion board 501 and a second direction conversion board 502. The first direction conversion board 501 is used to switch the running direction of the long section where the intermediate power supply board 4 is located to the G operating direction. The second direction conversion board 502 is used to switch the running direction of the long section where the intermediate power supply board 4 is located to the A operating direction. The port of the intermediate power supply board 4 used to output signal S1 is connected to the first direction conversion board 501, and the port used to output signal S2 is connected to the second direction conversion board 502. The running direction (G operating direction / A operating direction) of the long section where the intermediate power supply board 4 is located is switched through the output signals S1 and S2.

[0033] Indicator FG illuminates to indicate that the long section in the G operating direction is occupied or idle, while indicator FG is off to indicate that the long section in the A operating direction is occupied or idle. Conversely, indicator FA illuminates to indicate that the long section in the A operating direction is occupied or idle, while indicator FA is off to indicate that the long section in the G operating direction is occupied or idle. When signal FR is high, indicator FG is on and indicator FA is off; when signal FR is low, indicator FG is off and indicator FA is on.

[0034] Indicator S1 is used to indicate whether the G operating direction of the long section where the intermediate feeder board 4 is located is occupied or idle. When the output signal S1 is high, indicator S1 is lit, and the G operating direction of the long section where the intermediate feeder board 4 is located is occupied. When the output signal S1 is low, indicator S1 is off, and the G operating direction of the long section where the intermediate feeder board 4 is located is idle. When indicator FG is off, indicator S1 will definitely be off.

[0035] Indicator S2 is used to indicate whether the A operating direction of the long section where the intermediate power supply board 4 is located is occupied or idle. When the output signal S2 is high, indicator S2 is lit, and the A operating direction of the long section where the intermediate power supply board 4 is located is occupied. When the output signal S2 is low, indicator S2 is off, and the A operating direction of the long section where the intermediate power supply board 4 is located is idle. When indicator FA is off, indicator S2 will definitely be off.

[0036] See Figure 3 The image shows the normal operating state of the indicator light, where H represents a high level and L represents a low level. When the actual operating state of the indicator light differs from... Figure 3 If the results are inconsistent, the test results indicate a fault in intermediate power supply board 4. When the actual operating status of the indicator light is inconsistent with... Figure 3 If the results are consistent, the intermediate power supply board 4 is considered normal, and the staff will ultimately view the test results through the display module 3.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
