This necessitates prior communication between the two individuals regarding the testing method. Referring to the drawings, one person uses the red probe while the other uses the black probe to test each wiring of the high-speed turnout switch machine. This process typically takes about 30 minutes to complete, and accuracy is difficult to guarantee. More importantly, manual judgment is required to verify the correctness of the wiring. The long testing time, complex testing process, and difficulty in ensuring accuracy all contribute to this problem. It demands high technical skills from the personnel and requires at least two people to work together, significantly reducing efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following solution: A high-speed turnout switch machine wiring tester includes a housing consisting of an upper housing and a lower housing fixed together. A control board and a data acquisition board that communicate with the lower housing are fixedly installed on the inner side of the bottom plate. The control board and the data acquisition board are installed side by side.

A display screen is fixedly installed on the panel of the upper housing. The display screen is connected to the control board and is used to display the terminal pulse signals received by the acquisition board and transmitted to the control board, as well as the pin signals that receive the terminal pulse signals. The terminal pulse signals are sent from the wiring board of the speed-up turnout switch machine.

[0005] Furthermore, the speed-up turnout switch machine wiring tester also includes a speaker electrically connected to the control board, used to emit a prompt tone according to the signal from the control board.

[0006] Furthermore, the bottom plate of the lower housing has multiple centrally distributed horn sound holes.

[0007] Furthermore, the control board is used to determine whether the wiring of the speed-up turnout switch machine is accurate by comparing the received pin signals with the standard wiring data.

[0008] Furthermore, the terminals in the wiring board correspond one-to-one with the pins in the connection terminals of the speed-up turnout switch machine; The acquisition board is equipped with multiple signal transmission modules, and each signal transmission module is connected to a pin in the connection terminal of the speed-up turnout switch machine.

If the acquisition board receives the emitter signal of the optocoupler AN, it marks the corresponding pin signal as a positive pulse; otherwise, it remains silent. If the acquisition board receives the emitter signal of the optocoupler BN, it marks the corresponding pin signal as a negative pulse.

[0011] Further specifying, the test module includes a normally open optocoupler NA and a normally closed optocoupler NB; The control board is used to control the opening and closing of normally open optocoupler na and normally closed optocoupler nb respectively; When the normally open optocoupler na is closed and the normally closed optocoupler nb is open, a test pulse signal is output; When the normally open optocoupler NA is open and the normally closed optocoupler NB is closed, the receiving terminal pulse signal is received. The test module is cut off when the normally open optocoupler na is disconnected and the normally closed optocoupler nb is disconnected.

Detailed Implementation

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the specific implementation methods, structural features and effects of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0019] This embodiment provides a Figure 1 The speed-up turnout switch machine wiring tester shown includes a housing consisting of an upper housing 4 and a lower housing 5 fixed together. The bottom plate of the lower housing 3 has a... Figure 2 The control board 1 and the acquisition board 2 that communicate with it are shown; the control board 1 and the acquisition board 2 are installed side by side; wherein, the power switch 10 and the TYPC-E charging port 9 of the control board 1 are both fixedly installed at the end of the lower housing 3 on the side where the control board 1 is installed (i.e. Figure 2 The left end shown); while the speed-up turnout switch machine connection terminal 7 of the acquisition board 2 (i.e., the wire connection terminal for connecting the wire to the wiring terminal on the wiring board of the speed-up turnout switch machine) is fixedly installed. Figure 3 On the first side 11 of the mounting acquisition plate 2 on the lower housing 3 shown; on the second side 12 of the upper housing 4 directly opposite the first side 11, a terminal number identification plate 6 (i.e. an identification plate that sequentially marks the connection terminals 7 of the speed-up turnout switch machine) is fixedly installed.

[0020] To display test results or facilitate operation, this embodiment... Figure 1 A display screen 5 is fixedly installed on the panel 13 of the upper housing 4 shown, which is used to connect with the control board 1 to display the operation interface and various test information.

[0021] To facilitate the understanding of test results, this embodiment includes a sound control chip and a connected speaker on control board 1 to emit prompt voice messages. Figure 4 The bottom plate of the lower housing 3 shown has multiple centrally distributed speaker holes 8.

[0022] During wiring testing, control board 1 first sends a test pulse signal to the wiring under test via acquisition board 2. At the same time, it sends a query signal to acquisition board 2. Based on the query signal from control board 1, acquisition board 2 sends the terminal pulse signal A (the number of terminal pulse signals A is consistent with the number of terminals in the wiring board) and the pin signal receiving terminal pulse signal A to control board 1, and displays it on display screen 5. The pin signal is a mark set to distinguish the pins that correspond one-to-one with the terminals in the wiring board when receiving terminal pulse signal A or sending test pulse. The number of pins is consistent with the number of terminals.

[0023] Now combined with the appendix Figure 5 The above signal transmission is explained using nine terminals and nine pins as an example. The nine terminals in the high-speed turnout switch machine wiring board are A1 to A9, and the nine pins in the high-speed turnout switch machine connection terminal are M1 to M9. The corresponding pins are labeled with numbers 1 to 9 on the terminal number label 6.

[0024] Specific signal transmission or acquisition mainly includes Figure 5 The control circuit of the control board 1 shown is coordinated with Figure 6 The circuit of the acquisition board 2 shown is used to determine whether the wiring of the speed-up turnout switch machine is accurate by comparing the received pin signals with the standard wiring data.

[0025] Depend on Figure 5 As can be seen, control board 1 is controlled by the main control chip of the control board, and control board 1 is equipped with a wiring switching module and multiple test modules; The test module is used to control the transmission of test pulse signals and the reception of terminal pulse signal A; multiple test modules are connected one-to-one with the corresponding number of pins. At this time, there are 5 test modules, and the 5 test modules are connected one-to-one with pins M1 to M5 respectively; the remaining pins M6 to M9 are connected to the input and output terminals of the wiring switching module respectively. The wiring switching module is used to set the input and output capabilities of the remaining pins according to the wiring mode of the high-speed turnout switch machine.

[0026] Specifically, the test modules are optocouplers 1 to 5. Each test module includes a normally open optocoupler na and a normally closed optocoupler nb. For example, optocoupler 1 includes a normally open optocoupler 1a and a normally closed optocoupler 1b.

[0027] The following explanation uses the example of the main control chip on the control board controlling optocoupler 1 to send test pulse signal 1 and receive terminal pulse signal A: The positive terminals of normally open optocoupler 1a and normally closed optocoupler 1b receive high and low levels from the main control chip on the control board to control the opening and closing of the optocoupler. When both normally open optocoupler 1a and normally closed optocoupler 1b receive a high level, normally open optocoupler 1a closes and normally closed optocoupler 1b opens, outputting test pulse signal 1. When both normally open optocoupler 1a and normally closed optocoupler 1b receive a low level, normally open optocoupler 1a opens and normally closed optocoupler 1b closes, receiving terminal pulse signal A from the corresponding pin M. When normally open optocoupler 1a receives a low level and normally closed optocoupler 1b receives a high level, normally open optocoupler 1a opens and normally closed optocoupler 1b opens, the test module is cut off, and neither test pulse signal 1 is sent nor terminal pulse signal A is received.

[0028] To further explain, the wiring switching module includes a first overcurrent module, a diode Z1, and a second overcurrent module connected in sequence. The first overcurrent module is an optocoupler 6, and the second overcurrent module is an optocoupler 7. The optocoupler 6 includes a normally open optocoupler 6a and a normally closed optocoupler 6b connected in series. Similarly, the optocoupler 7 includes a normally open optocoupler 7a and a normally closed optocoupler 7b connected in series. The normally open optocoupler 6a is connected to pins M6 and M7, respectively, and the optocoupler 7 is connected to pins M8 and M9, respectively.

[0029] Specifically, there are two wiring modes for the high-speed turnout switch machine: 1,3 closed positioning wiring and 2,4 closed positioning wiring, which are abbreviated as 1,3 wiring and 2,4 wiring, respectively. When the wiring mode of the high-speed turnout switch machine is 1,3 wiring, pins M6 and M7 are connected to the positive terminal of diode Z1, and pins M8 and M9 are connected to the negative terminal of diode Z1. The main control chip on the control board sends a high level to optocouplers 6 and 7, so normally open optocouplers 6a and 7a are closed, and normally closed optocouplers 6b and 7b are open. When the switch is turned on, the current moves in the direction of the thin arrow. The pulse signal 6 or pulse signal 7 from terminal A6 or terminal A7 is connected to the positive terminal of diode Z1 and then re-enters terminal A8 or A9 through pin 8 or pin 9. When the wiring mode of the high-speed turnout switch machine is 2 or 4 wiring, pins M6 and M7 are connected to the negative terminal of diode Z1, and pins M8 and M9 are connected to the positive terminal of diode Z1. The main control chip of the control board sends a low level to both optocoupler 6 and optocoupler 7. At this time, the current moves in the direction of the thick arrow.

[0030] In actual testing, it is necessary to confirm the wiring mode of the high-speed turnout switch machine in advance. After confirming the wiring mode, the wiring of each terminal can be determined for accurate wiring. Correspondingly, it can be determined which terminals can send terminal pulse signal A after receiving the test pulse signal, so as to pre-store the standard wiring data for different wiring modes. Under the same wiring mode, due to the different positions of the gate, that is, when the turnout position is in the fixed or reverse position, the terminals that send terminal pulse signal A after receiving the test pulse signal are different. Therefore, it is necessary to determine the wiring mode and position of the high-speed turnout switch machine before testing. There are 4 types of standard wiring data, corresponding to the 1,3 wiring fixed position, 1,3 wiring reverse position, 2,4 wiring fixed position, and 2,4 wiring reverse position. After determining the wiring mode and position of the high-speed turnout switch machine to be tested, the standard wiring data of the corresponding mode and position is automatically extracted.

[0031] The wiring mode and position of the turnout switch machine under test are selected via display screen 5. Subsequently, the main control chip of the control board sends control signals to the corresponding test modules to transmit the corresponding test pulse signals and receive the terminal pulse signals A of the other test modules. In order to facilitate recording which pins transmitted test pulse signals and which pins received terminal pulse signals A, the acquisition board 2 marks the pins that transmitted or received signals to obtain pin signals. After that, the acquisition board 2 sorts the pin signals in order, encodes them, and sends them to the control board 1 through the UART communication interface. After parsing, the main control chip of the control board compares the pin signals with the standard wiring data. If they match, it means that the wiring is accurate and a correct prompt is given through the speaker. If they do not match, it means that the wiring is inaccurate and an error prompt is given through the speaker. The display screen 5 also displays the result.

[0032] To further explain, the acquisition board 2 is equipped with multiple signal transmission modules, and the signal transmission modules are connected one-to-one with the pins in the connection terminal 7 of the speed-up turnout switch machine; the number of signal transmission modules is the same as the number of pins, which is 9, namely signal transmission module 1 to signal transmission module 9.

[0033] The signal transmission module is used to send the test pulse signal generated by the control board 1 to the corresponding terminal in the wiring board; it is used to send the terminal pulse signal A generated by the terminal in the wiring board to the acquisition board 2; the acquisition board 2 is used to acquire the pin signal of the test pulse signal sent by the signal transmission module and the pin signal of the terminal pulse signal A received by the signal transmission module and send them back to the control board 1.

[0034] For details, please refer to Figure 6 The signal transmission module includes an optocoupler and bn optocoupler, where n is the nth signal transmission module. In this case, we will take n=1 as an example for explanation.

[0035] The positive terminal of optocoupler a1 is connected to the test pulse signal output terminal of control board 1, the negative terminal of optocoupler a1 is connected to the corresponding terminal in the wiring board, the collector of optocoupler a1 is connected to the acquisition voltage, and the emitter of optocoupler a1 is connected to acquisition board 2; the positive terminal of optocoupler b1 is connected to the corresponding terminal in the wiring board, the negative terminal of optocoupler b1 is connected to the test pulse signal output terminal of control board 1, the collector of optocoupler b1 is connected to the acquisition voltage, and the emitter of optocoupler b1 is connected to acquisition board 2.

[0036] When test pulse signal 1 is sent, optocoupler a1 is turned on, and acquisition board 2 receives the emitter signal of optocoupler a1 and marks the corresponding pin signal as positive pulse 1+, otherwise it is silent; when terminal A1 sends terminal pulse signal A, acquisition board 2 receives the emitter signal of optocoupler b1 and marks the corresponding pin signal as negative pulse 1-, otherwise it is silent; acquisition board 2 is used to send the marked positive and negative pulses back to control board 1.

[0037] For example, if test pulse signal 1 is sent through the main control chip of the control board, the signal transmission module 1 sends test pulse signal 1 to terminal A1 through pin M1. At this time, the acquisition board 2 marks the positive pulse 1+. Subsequently, test pulse signal 1, as a terminal pulse signal, enters the signal transmission module 3 and signal transmission module 4 from terminals A3 and A4 through pins M3 and M4. At the same time, the acquisition board 2 marks the reverse pulses 3- and 4-. Then, 1+, 3-, and 4- are sent to the main control chip of the control board in sequence. If, in the standard wiring data of the 1,3 wiring position, terminal A1 receives test pulse signal 1 and the pin signals are 1+, 3-, and 4, it means that the current wiring of terminal A1 is accurate. Otherwise, if the pin signals acquired by the acquisition board 2 are inconsistent with the standard wiring data, it means that the wiring of the terminal is incorrect. At this time, the error in the wiring of terminal A1 is announced through the speaker and displayed on the display screen 5, along with the incorrect pin signals.

[0038] The entire process described above requires only one operator, who does not need to have relevant professional testing knowledge. As long as they know the operating steps, they can avoid the drawbacks of traditional two-person testing, such as unreliable measurement results, large workload, low efficiency, and high requirements for operators.

[0039] Example 2 Based on the high-speed turnout switch machine wiring tester provided in Embodiment 1, this embodiment provides a high-speed turnout switch machine wiring test method, including the following steps: S1. Determine the wiring mode of the current speed-up turnout switch machine, and set the input and output capabilities of the connected terminals through the wiring switching module; S2, Control board 1 controls the test module corresponding to the terminal under test to output test pulse signals, and outputs the test pulse signals to the terminal under test through the corresponding signal transmission module; S3, Control board 1 controls the other test modules to receive terminal pulse signal A; S4. Acquisition board 2 acquires the pin signals of the test pulse signal sent by the signal transfer module and the pin signals of the terminal pulse signal A received by the other signal transfer module. After sorting and encoding the obtained pin signals, it sends them back to control board 1. S5. Control board 1 will compare the decoded pin signals with the standard wiring data. If the comparison is consistent, the wiring of the terminal under test is accurate; otherwise, the wiring of the terminal under test is incorrect, and the current terminal number and pin number will be recorded. S6. Determine whether the testing of all terminal wiring has been completed. If yes, proceed to step S7; otherwise, select the next terminal to be tested and repeat steps S2 to S6. S7. Manually switch the turnout position, and after re-execute steps S1~S6, execute step S8. S8. Determine whether all terminal wiring is accurate. If yes, the wiring of the current speed-up turnout switch machine is accurate; otherwise, the wiring is inaccurate.

[0040] To further explain, for different wiring modes and positions, terminals A1 to A5 are tested one by one to determine whether the wiring of each terminal is accurate under the current wiring mode and position. After the determination is completed, the turnout is manually switched to change the position under the current wiring mode, and then the determination of whether the wiring of each terminal is accurate is repeated. If the wiring of terminals in different positions is accurate, then the wiring of the speed-up turnout switch machine is accurate; otherwise, it is inaccurate.

[0041] For details, see Figures 8-17 These are schematic diagrams illustrating the wiring test process of terminals A1~A5 of the high-speed turnout switch machine under different wiring patterns and positions. (Refer to...) Figure 7 This is a diagram illustrating the testing process.

[0042] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
