DETAILED DESCRIPTION

[0026] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of devices consistent with certain aspects of the present invention as detailed in the appended claims.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0028] See also Figures 1 to 5 The present invention provides a test device for detecting a subway electronic door control unit, comprising an MCU 1, the MCU 1 being connected to a motor encoder 2, a current sensor 3, a power conversion module 4, a storage module 5, and a display module 6. The motor encoder 2, the current sensor 3, and the power conversion module 4 are all connected to the subway electronic door control unit. Specifically, the electronic door control unit comprises a power supply, a drive motor, and a door closing / starting / locking integrated logic control unit connected to the drive motor.

[0029] The motor encoder 2 and the current sensor 3 are both connected to the drive motor, the power conversion module 4 is connected to the power supply, the door closing / starting / locking integrated logic control unit is connected to the drive motor, and the door closing / opening / locking integrated logic control unit is connected to the MCU 1 and the drive motor respectively.

[0030] Specifically, the current sensor 3 is used to monitor the current of the drive motor and send the current data to the MCU 1; the motor encoder 2 is used to monitor the operating status of the drive motor and send the status data to the MCU 1; the power conversion module 4 is used to convert the power of the electronic door control unit into a power supply that can be used by the MCU 1.

[0031] In this embodiment, the test device uses MCU 1 as the control core to detect the output signal of the subway's electronic door control unit (EDCU) and control the electronic door control unit, thereby realizing diversified testing. Specifically, the integrated logic control unit for door closing / starting / locking controls the drive motor, sends a door signal to the drive motor, and the drive motor performs the corresponding action. The motor encoder 2 monitors the operating status of the drive motor and sends the position, speed, and direction of the drive motor to MCU 1. At the same time, the current sensor 3 monitors the current of the drive motor and sends the current data to MCU 1. After receiving the position, speed, direction, and current data of the drive motor, the MCU 1 performs data conversion and sends the received data to the display module 6 for display, providing intuitive data feedback to the operator; at the same time, it sends it to the storage module 5 to record the operation data and historical operation information for subsequent analysis and tracing.

[0032] When the MCU 1 detects that the temperature transmitted by the current sensor 3 is higher than the normal operating temperature range, the drive motor may have an abnormality. At this time, further testing of the drive motor is required. Otherwise, the drive motor operates normally, thereby ensuring the normal operation of the device.

[0033] Among them, the door closing / opening / locking integrated logic control unit sends out door opening signal, door closing signal, zero speed signal and enable signal, such as Figure 4 As shown, this is the prior art and will not be described again here.

[0034] It should be noted that MCU 1 only detects the signal from motor encoder 2 without any processing or feedback, to ensure the integrity of the original signal. Through this non-interference detection method, MCU 1 can understand the operating status of the drive motor in real time while ensuring the authenticity of the signal.

[0035] In this embodiment, the power supply of the electronic door control unit is connected to the power conversion module 4, which is connected to the MCU 1 to provide power to the MCU 1. Specifically, the power conversion module 4 converts the 110V voltage bus of the train into an integrated power supply that can be used by the test device.

[0036] Furthermore, the test device further includes an analog signal module 7 , which is connected to the MCU 1 and the vehicle door closing / opening / locking integrated logic control unit respectively.

[0037] Furthermore, the analog signal module 7 includes an analog door opening signal circuit 71, an analog door closing signal circuit 74, an analog enable signal circuit 72 and an analog zero speed signal circuit 73;

[0038] The simulated door opening signal circuit 71 , the simulated door closing signal circuit 74 , the simulated enable signal circuit 72 and the simulated zero speed signal circuit 73 are all connected to the vehicle door closing / opening / locking integrated logic control unit and the MCU 1 , respectively.

[0039] It should be noted that the simulated door opening signal circuit 71, the simulated door closing signal circuit 74, the simulated enable signal circuit 72, and the simulated zero-speed signal circuit 73 all have only low and high levels. For example, when the simulated door opening signal circuit 71, the simulated enable signal circuit 72, and the zero-speed signal circuit 73 are high, and the simulated door closing signal circuit 74 is low, the vehicle door closing / opening / locking integrated logic control unit controls the drive motor to rotate and open the vehicle door.

[0040] In this embodiment, the circuits of the simulated door opening signal circuit 71, the simulated door closing signal circuit 74, the simulated enable signal circuit 72 and the simulated zero speed signal circuit 73 are Figure 1 The only difference is the interface, that is, the peripheral network is different. Take one of the circuit schematics as an example. Figure 5As shown, this is the schematic diagram of the door opening signal circuit of the present invention, which can realize three functions. The first is the signal reading circuit A, MCU 1 reads the EDCU output interface signal, and detects the high / low level of the EDCU output interface signal. Specifically, the EDCU interface from the vehicle sends a door opening signal instruction, which is input through the Open door signal interface and sent to MCU 1 after voltage division by resistors R5 and R6. MCU 1 will read the voltage value at this point through ADC to read the input signal. At this time, the transistor Q3 is at a high level, and the port 5 and port 3 of the relay RLY1 are disconnected. At this time, it is guaranteed that MCU 1 reads the EDCU output interface signal; the second is the EDCU signal control door opening test circuit B. The test device can turn on and off the signal from the vehicle interface to the EDCU to decide whether the vehicle interface should be sent to the EDCU. Specifically, the EDCU interface from the vehicle sends a door opening signal instruction, which is input through the Open door signal interface and sent to MCU 1 after voltage division by resistors R5 and R6. 1. The voltage value at this point is read through the ADC to read the input signal. At this time, transistor Q3 is at a low level, and ports 5 and 3 of relay RLY1 are connected. This signal can be sent to the EDCU to perform the vehicle door opening test. Third, the simulated door opening signal circuit 71 shields the vehicle signal and sends a signal to the EDCU through this test device. The control chip U3 outputs a high or low level. If the output is a high level, the 110V voltage enters the EDCU through transistor Q7. If the output is a low level, it is directly connected to ground through transistor Q8. It should be noted that the present invention is not limited to the circuit diagram; as long as it can achieve the required function, it will be sufficient.

[0041] like Figure 3 As shown, the test device also includes a motor circuit switch 8 for controlling the drive motor switch. The motor circuit switch 8 is connected to the door closing / opening / locking integrated logic control unit and the MCU 1. Specifically, the motor circuit switch 8 comprises three relays, each connected to the three-phase circuit of the drive motor. When the three relays are activated simultaneously, the door closing / opening / locking integrated logic control unit receives the signal and turns on the drive motor. When the three relays are deactivated, the drive motor is turned off.

[0042] Furthermore, the testing device further includes a remote sensing control module 9 , which is connected to the MCU 1 .

[0043] like Figure 2 As shown, the remote sensing control module 9 includes a door opening / closing trigger key 91, an analog enable signal circuit opening / closing trigger key 92, an analog zero speed signal circuit opening / closing trigger key 93, and a motor circuit switch trigger key 94, which are respectively connected to the MCU 1.

[0044] In this embodiment, by operating the corresponding trigger key, MCU 1 receives the instruction to determine and open the corresponding analog signal circuit. After receiving the signal, the door closing / opening / locking integrated logic control unit further controls the operation of the drive motor, thereby realizing the test of the electronic door control circuit. The test result is obtained by observing the response signal of the subway electronic door control circuit.

[0045] Specifically, the motor circuit switch trigger key 94 is used to send an on / off electrical signal to the motor circuit switch 8, thereby controlling the operating state of the drive motor. When control of the drive motor is required, the MCU 1 can also use the motor circuit switch trigger key 94 to open or close the motor circuit switch 8 to control the operation of the drive motor. This function is particularly important during debugging or emergency situations, ensuring the safety of the drive motor and related equipment.

[0046] Furthermore, the display module 6 is a tablet computer or a display.

[0047] Furthermore, the MCU 1 is provided with a host computer interface 10 , which is used to enable the MCU 1 to communicate with a host computer, thereby realizing remote monitoring and debugging, and improving the management efficiency of the test device.
