Description
Technical Field
[0001] This utility model belongs to the field of controller testing technology, specifically relating to a permanent magnet switch controller testing device. Background Technology
[0002] The mining permanent magnet switch controller is the core control component of the mining permanent magnet switch. It is responsible for driving the closing / opening coil, monitoring the charging and discharging of the energy storage capacitor, and controlling the corresponding alarm outputs. In most cases, permanent magnet switch failures are caused by controller malfunctions. Current testing methods involve temporarily installing the controller under test into a normal mining permanent magnet switch and observing its response through actual closing / opening operations. This method cannot independently assess the controller's performance integrity and relies on the switch itself as the test platform, limiting the testing process to equipment availability and site conditions. If the controller under test has a latent fault, directly connecting it to a functional permanent magnet switch may burn out the controller or switch due to current or voltage mismatch. Furthermore, temporary wiring between the controller and permanent magnet switch is complex and prone to short circuits, reverse connections, and other accidents due to incorrect connections or poor contact. The testing process also requires repeated disassembly and reassembly of the switch, which is time-consuming and prone to human error.
[0003] Therefore, there is an urgent need for a dedicated testing device for permanent magnet switch controllers that can directly simulate load conditions without relying on the switch itself. Utility Model Content

[0065] The working principle of the permanent magnet switch controller testing device provided by this utility model is as follows:
[0066] Power supply section:
[0067] The AC220V power supply (L, live wire) is connected to pin X1 of aviation socket 7, passes through emergency stop switch S2 and fuse F1, and then enters the upper end of contactor K9 via the N (neutral wire) connected to pin 2 of aviation socket 7. The lower end of contactor K9 is connected to the first power indicator light L1. When power switch S1 is pressed, contactor K9 engages, and the first power indicator light L1 illuminates, indicating that the device is powered on. AC220V power is output from the lower end of contactor K9 to pins X3 and X4 of aviation socket 7 to power the controller under test. Simultaneously, it is output to power converter U2. Power converter U2 converts the input AC220V power into DC24V control power for the device, powering the PLC controller 6 and touch screen P8. When power converter U2 outputs DC24V power, the second power indicator light L2 illuminates, and the PLC controller 6 and touch screen P8 are powered on and started. After the controller under test is connected to the working power supply through the X3 and X4 pins / holes of the aviation socket 7, its internal power converter generates another set of DC24V (W24V), which is input into the device through the X15 and X16 pins / holes of the aviation socket 7.
[0068] Functional components:
[0069] When the closing switch S3 is pressed or the virtual closing button 801 is pressed, the closing command is output by Q0.1 of the PLC controller 6. The closing indicator L8 and the virtual closing indicator 803 light up synchronously. The closing command is output to the controller under test through the X20 pin / hole of the aviation socket 7. If the controller under test functions normally after receiving the closing command, it will output a closing signal at pins / holes X11 and X14 of the aviation socket 7, energizing the closing coil 301 and closing the switch. At the same time, it will output another combination closing signal at pins / holes X24 and X25 of the aviation socket 7 to I0.5 of the PLC controller 6. The PLC controller 6 will process the signal and output it through Q0.5 to the closing output indicator L5 and the touch screen P8, causing the closing output indicator L5 and the virtual closing output indicator 807 to light up or flash. At the same time that the closing and opening actuator 3 completes the closing, the interlocking feedback mechanism 5 will synchronously generate an opening status signal and send it synchronously to I0.3 of the PLC controller 6. The PLC controller 6 will process the signal and send it through Q0.3 to the closing position indicator L3 and the touch screen P8, causing the closing position indicator L3 and the virtual closing position indicator 805 to light up.
[0070] When the trip switch S4 is pressed or the trip button 802 is pressed, the PLC controller 6 outputs a trip command via Q0.2, and the trip indicator light L9 illuminates. The trip command is output to the controller under test via pin 21 of the aviation socket 7. If the controller under test functions normally after receiving the trip command, it will output a trip signal via pins 12 and 13 of the aviation socket 7, energizing the trip coil 302 and tripping the switch. Simultaneously, another trip signal is output via pins 26 and 27 of the aviation socket 7 to I0.6 of the PLC controller 6. The PLC controller 6 processes this signal and sends it via Q0.6 to the trip output indicator light L6 and the display screen P8, causing the trip output indicator light L6 and the virtual trip output indicator light 808 to illuminate or flash. The interlocking feedback mechanism 5 generates a tripping status signal simultaneously with the tripping actuator 3 completing the tripping operation. This signal is then sent to I0.4 of the PLC controller 6. The PLC controller 6 processes the signal and sends it to the tripping indicator L4 and the display screen P8 via Q0.4, causing the tripping indicator L4 and the virtual closing indicator 805 to light up.
[0071] When the controller under test has an alarm output, the alarm signal is output through pins 28 and 29 of the aviation socket 7. I0.7 of the PLC controller 6 is energized. The PLC controller 6 processes the signal and outputs it through Q0.7 to the alarm output indicator L7 and the display screen P8, causing the physical alarm indicator L7 and the virtual alarm indicator 809 to light up or flash. When the opening or closing process is completed, the physical alarm indicator L7 and the virtual alarm indicator 809 flash three times, indicating that the operation timed out.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
