[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the specific implementation methods thereof are described in detail below with reference to the accompanying drawings:

[0038] See also Figures 1 to 11 In a preferred embodiment of the present invention, a parking system control cabinet includes a parking system controller PLC2, a parking system control cabinet touch screen OP2, and a parking system control cabinet power supply UO2. An automatic detection device for a mechanical parking system control cabinet includes a detection controller PLC1, a detection touch screen OP1, a switching power supply UO1, relays KA1, KA2, and KA3.

[0039] RS485 communication is adopted between the detection controller PLC1 and the detection touch screen OP1. The switching power supply UO1 is connected to the 220V AC power supply. The switching power supply UO1 converts the single-phase 220V power supply into DC24V power supply to power the detection controller PLC1 and the detection touch screen OP1.

[0040] The output end of the detection controller PLC1 is connected to the input end of the parking equipment controller PLC2. In this embodiment, the output points Q0.1 to Q0.7, output points Q1.0 to Q1.7, and output points Q2.0 to Q2.3 of the detection controller PLC1 are connected to X01 to X23 of the parking equipment controller PLC2 one by one.

[0041] The motor forward input and reverse input points of the detection controller PLC1 are connected to a positive phase sequence relay and a negative phase sequence relay in a one-to-one correspondence. These paired positive and negative phase sequence relays detect the output and direction of each motor in the parking system control cabinet. The detection results are converted into PLC input signals and fed into the detection controller PLC1. Each phase sequence relay uses a phase sequence relay with undervoltage and overvoltage detection.

[0042] In this embodiment, Figure 4 and Figure 5 As shown, in this embodiment, there are three lifting motors M21 to M23 and two traverse motors M11 to M12. The lifting motor M21 is output from the parking equipment control cabinet to the lifting motor terminal block U21, V21, and W21. The lifting motor M22 is output from the parking equipment control cabinet to the lifting motor terminal block U22, V22, and W22. The lifting motor M23 is output from the parking equipment control cabinet to the lifting motor terminal block U23, V23, and W23. The traverse motor M11 is output from the parking equipment control cabinet to the traverse motor terminal block U11, V11, and W11. The traverse motor M12 is output from the parking equipment control cabinet to the traverse motor terminal block U12, V12, and W12. Figure 1The example shows the use of two positive and negative phase sequence relays (XJ1-XJ2) to detect whether the phase sequence of the three-phase 380V power output from the parking equipment control cabinet motor is correct. Taking the positive phase sequence relay XJ1 and the negative phase sequence relay XJ2 as an example, when the positive phase sequence relay XJ1 detects that the three-phase 380V output is correct at the lifting motor terminal block U21, V21, and W21, the normally open contacts Ta and Tc of the positive phase sequence relay XJ1 are conductive, and the motor forward input point (phase sequence relay input point) I0.4 of the detection controller PLC1 is conductive. Input point I0.4 indicates that the lifting motor M21 is running upward (upward). If the power output from the lifting motor terminal block U21, V21, and W21 is reversed, the normally open contacts Ta and Tc of the negative phase sequence relay XJ2 are conductive, and the motor reverse input point (phase sequence relay input point) I0.5 of the detection controller PLC1 is conductive. Input point I0.5 indicates that the lifting motor M21 is running downward (downward). In this way, the output direction of the lifting motor and the transverse motor can be monitored in real time through the positive and negative phase sequence relays used in pairs.

[0043] The meaning of the phase sequence relay input points of the detection controller PLC1 is shown in Table 1. The phase sequence relay input points of the detection controller are defined in the detection controller PLC1 program. Figure 8 .

[0044] Table 1, the meaning of the phase sequence relay input points of the detection controller PLC1:

[0045]

[0046]

[0047] Relay KA1 monitors the parking system control cabinet power supply UO2. Once UO2 is functioning properly, relay KA1 outputs a signal, which is then connected to the detection controller's power input I0.0 via the corresponding relay KA1 input point. The detection controller's power input I0.0 is then turned on. The parking system controller PLC2's warning light output Y01 and buzzer output Y02 are connected to relays KA2 and KA3, respectively, and then connected to the detection controller's warning light input I0.1 and buzzer input I0.2 via the corresponding relay input points.

[0048] See also Figure 9 The output point of the detection controller PLC1 provides an input signal to the parking equipment controller. For example, the loop conduction output point Q0.0 of the detection controller PLC1 is used to provide the loop conduction input signal to the parking equipment controller. Once the loop conduction output point Q0.0 of the detection controller has an output, the input point X00 of the parking equipment controller PLC2 is connected to the input point 24V-, and the safety circuit of the entire parking equipment control cabinet is connected.

[0049] See also Figure 10 and Figure 11 The detection controller PLC1 has a main program module and a subroutine module connected thereto. The main program module 21 can call the subroutine module. Figure 11 It shows that the output is set when the forward limit switch and reverse limit switch of the subroutine reach the running time.

[0050] See also Figure 6 and Figure 7 By adjusting the motor running time on the detection touch screen OP1, the motor running timeout and undertime protection function of the parking equipment control cabinet is verified. The lifting running time MD100 and the lateral movement running time MD104 are adjustable on the detection touch screen OP1. By adjusting the running time, the time of the limit switch action is adjusted, thereby artificially causing running undertime faults and overtime faults. If the running time set on the detection touch screen is shorter than the corresponding minimum running time set by the parking equipment control cabinet, the parking equipment control cabinet will report an undertime fault. If the running time set on the detection touch screen is longer than the corresponding maximum running time set by the parking equipment control cabinet, the parking equipment control cabinet will report an overtime fault. For example, by adjusting the lifting running time MD100, if the set lifting running time MD100 is shorter than the minimum running time set by the parking equipment control cabinet system, the parking equipment control cabinet will report an undertime fault. If the set lifting running time MD100 is longer than the maximum running time set by the control cabinet system, the control cabinet system will report an overtime fault.

[0051] The automatic detection device of the present invention also has the following functions:

[0052] (1) Since the automatic operation state of the parking equipment can be simulated together with the parking equipment control cabinet, once the output and input points of the PLC program in the parking equipment control cabinet are defined incorrectly, the automatic operation cannot be simulated and an error will be reported. Once it is found that there is no automatic operation, it will be found that the input and output points of the PLC program in the parking equipment control cabinet may be defined incorrectly.

[0053] (2) The automatic detection device can also be used as a verification device for newly developed parking equipment PLC programs. By simulating the sequential actions of the parking equipment limit switches throughout the process, the correctness of the parking equipment PLC program can be verified, which can effectively help parking equipment PLC program engineers debug.

[0054] The automatic detection device for the mechanical parking system control cabinet of the present invention can simulate the automatic operation of the parking system to verify the correct wiring and contactor wiring sequence of the parking system control cabinet, as well as simulate the triggering of parking system control cabinet faults, thereby verifying the functioning of the parking system control cabinet software. This automatic detection device monitors the motor's running direction by converting three-phase motor detection into switching signals. Software functions provide a delayed output to the control cabinet to provide sequential limit switch action signals, simulating the actual operation of the parking system, where the vehicle carrier plate runs for a certain period of time and then contacts the limit switch. Furthermore, the operation time can be adjusted on the touch screen to verify the functioning of the parking system's under- and overtime protection functions. The device can also verify the correct definition of the PLC input and output point programs within the parking system control cabinet.

[0055] In summary, the automatic detection device for the mechanical parking equipment control cabinet of the present invention can verify the correctness of the newly developed parking equipment PLC program, and can also assist the parking equipment PLC program engineer in debugging tools, so that the parking equipment PLC program can be verified and debugged in the factory.

[0056] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
