[0073] Input signal description;
[0074] <1> Emergency stop signal [X0]: The emergency stop signal controls the start and stop of the entire garage and is the highest priority switch signal;
[0075] <2> Advance photoelectric signal [X1]: When a vehicle enters the garage and blocks the photoelectric signal, this signal will be triggered. This signal is used to determine whether the front end of the vehicle is ahead;
[0076] <3> Overtaking photoelectric signal [X2]: When a vehicle enters the garage, the rear end of the vehicle blocks the photoelectric trigger signal. This signal is used to determine whether the rear end of the vehicle has overtaken.
[0077] <4> Phase sequence and overload protection signal [X3]: This signal is triggered when the circuit has phase loss, phase error, undervoltage, or motor overheating;

[0082] <9> Upper limit signal [X10-X15]: When the lifting platform reaches the designated position, this signal will be triggered and the lifting of the platform will stop;
[0083] <10> Transverse movement signal [X16-X23]: When the transverse movement plate moves to the right position, this signal will be triggered and the transverse movement of the plate will stop.
[0084] (2) Troubleshooting
[0085] The fault processing module is used to obtain a fault signal according to the input signal corresponding to each switch and the parking space number, and output it to the signal output module.
[0086] Fault handling is the most important part of the program. To ensure the safe and stable operation of the garage, faults are very important in PLC program processing. D240 is the fault code register, and the corresponding decimal number represents the corresponding fault. The types of lifting and traversing faults are as follows:
[0087] <1> Emergency stop fault [k1]: The emergency stop fault controls the start and stop of the entire garage. It is the highest priority fault type. This fault not only stops the garage but also returns all registers in the program to their initial states.
[0088] <2> Phase sequence and overload fault [k41]: When the three-phase circuit has undervoltage, overvoltage, phase failure, phase loss, or motor overload, the phase sequence and overload fault will be triggered;
[0089] <3> Vehicle ahead fault [k2]: When a vehicle blocks the ahead photoelectric sensor, the vehicle ahead fault is triggered. This fault detects whether the vehicle is ahead.
[0090] <4> Vehicle overtaking fault [k3]: When a vehicle blocks the overtaking photoelectric sensor, the vehicle overtaking fault is triggered. This fault detects whether the rear end of the vehicle is overtaking.
[0091] <6> Loose chain fault [k17]: When the chain becomes loose while the vehicle is ascending or descending, a loose chain fault will be triggered, the vehicle will stop, and the fault will remain. After the chain relaxation process is normal, it can be cleared manually on the operator;
[0092] <7> Upper and lower limit fault [k42]: When the lift plate is rising or falling, if the upper or lower limit signal does not work, it will hit the upper and lower limit switches, triggering the upper and lower limit fault, and the fault will remain. After the limit switch is reset, it can be cleared manually on the operator;
[0093] <8> Anti-fall hook malfunction fault [k50]: When the garage is not running, the electromagnet signal is triggered, and the anti-fall hook malfunction fault is reported;
[0094] <9> Anti-fall hook not open fault [k51]: When the garage is lifting, the electromagnet signal is not triggered, and the anti-fall hook not open fault is reported;
[0095] <10> Transverse shift failure [k11]: In automatic or card swiping mode, if the transverse shifting plate is not in place, a transverse shift failure will be reported. Press the emergency stop button and enter manual mode. Only after the plate is moved transversely into place can the automatic mode be entered.
[0096] <11> Transverse full-pass fault [k18]: When all the transverse switches in the garage have signals, a transverse full-pass fault will be triggered. The garage cannot operate and cannot enter manual, automatic, or card swiping modes. This fault type has a higher priority.
[0097] <12> Upper and lower limit fault [k43]: When the upper limit in the garage is fully open and there is a signal at the lower limit, an upper and lower limit fault will be triggered. The garage cannot operate and cannot enter manual, automatic, or card swiping modes. This fault type has a higher priority.
[0098] <13> Raising failure [k9]: In automatic and card swiping modes, when the garage is not running, the lateral platform is not in place, and the lifting platform is not raised or lowered, the raising failure fault will be triggered. After this fault occurs, press the emergency stop button and enter manual mode. After the platform is raised or lowered, it can be operated in automatic and card swiping modes.
[0099] <14> Invalid parking space number fault [k76]: When the number input on the operator exceeds the number of parking spaces specified in the garage, an invalid parking space number fault will be reported;
[0100] <15> Transverse movement timeout fault [k15]: In automatic and card swiping modes, when the transverse movement time of the vehicle plate exceeds the set maximum time during the transverse movement, a transverse movement timeout fault will be triggered. This fault type is to prevent the vehicle plate from continuing to move transversely when the transverse movement signal is lost;
[0101] <16> Lateral movement undertime fault [k105]: In automatic and card swiping modes, when the lateral movement time of the vehicle plate is less than the set minimum time during lateral movement, a lateral movement undertime fault will be triggered. This fault type is to prevent the lateral movement switch from malfunctioning.
[0102] <17> Lift Timeout Fault [k14]: In automatic and card swiping modes, when the lifting time of the vehicle plate exceeds the set maximum time during the lifting process, a lift timeout fault will be triggered. This fault type is to prevent the vehicle plate from continuing to lift when the upper limit signal is lost;
[0103] <18> Lifting undertime fault [k106]: In automatic and card swiping modes, when the lifting time of the vehicle plate is less than the set minimum time during the lifting process, the lifting undertime fault will be triggered. This fault type is to prevent the upper limit or lower limit from malfunctioning when running in automatic and card swiping modes;
[0104] (3) Running program part
[0105] The running program module is connected to the host computer for communication, and is used to switch the control mode of the stereo parking garage according to the manual control data, automatic control data or card swiping control data output by the host computer; in the manual control mode, the corresponding manual control operation result is obtained according to the manual control data output by the host computer, and is output to the signal output module; in the automatic control mode, the corresponding automatic control operation result is obtained according to the automatic control data output by the host computer, and is output to the signal output module; in the card swiping control mode, the corresponding card swiping control operation result is obtained according to the card swiping control data output by the host computer, and is output to the signal output module.
[0106] There are three modes for running the program: manual, automatic, and card swiping. Details are as follows:
[0107] <1> Manual mode.
[0108] In manual mode, the operation status of the garage can be controlled by pressing the four direction keys of up, down, left and right on the upper computer operator. Manual mode is a jog operation. When the corresponding key is pressed, the register value is set to 1 and reset to 0 when released. The four direction keys must be interlocked. The following is a detailed description of the auxiliary relays and registers used in manual mode:
[0109] Manual mode [M6]: Manual mode auxiliary relay;
[0110] Up key [D2]: controls the motor to manually rise;
[0111] Down button [D3]: Controls the motor to manually descend;

[0116] Manual rise [M201]: Motor manual rise auxiliary relay;
[0117] Manual descent [M202]: Motor manual descent auxiliary relay;
[0118] <2> Automatic / swipe mode.
[0119] In automatic or card swiping mode, enter the parking space number or swipe the card through the host computer operator, and then press the confirmation key [D6], the garage will automatically operate to achieve the purpose of parking and retrieval. The following are the auxiliary relays used in automatic and card swiping modes and their detailed descriptions:
[0120] Automatic mode [M4]: Automatic mode auxiliary relay;
[0121] Card swiping mode [M5]: Card swiping mode auxiliary relay;
[0122] Automatic left shift [M124]: The motor automatically shifts left auxiliary relay. In automatic or card swiping mode, when the lifting platform is fully raised and the parking space is on the right side of the vacant space, it will trigger automatic left shift;
[0123] Automatic right shift [M125]: The motor automatically shifts right auxiliary relay. In automatic or card swiping mode, when the lifting platform is fully raised and the occupied parking space is on the left side of an empty space, it will trigger automatic right shift;
[0124] Automatic rise [M102]: The motor automatically rises auxiliary relay. In the automatic or card swiping mode, the lifting plate has a lowering position and the horizontal moving plate moves horizontally into position.
[0125] Then trigger automatic rise;
[0126] Automatic descent [M145]: This relay activates the motor's automatic descent auxiliary relay. In automatic or card swipe mode, automatic descent is triggered when all lift plates are fully raised and the requested parking space matches an empty space. When the space hits the lower limit, descent stops, and the system completes operation. The four operating states of automatic left shift, automatic right shift, automatic ascent, and automatic descent must be interlocked. If a system fault occurs, automatic operation stops and the PLC registers are cleared.
[0127] (4) Content display part
[0128] The content display is through RS 485 communication, and the PLC sends data to the host computer, which displays the current status of the garage. The display content includes the current status information and the current parking space number. The specific display content is as follows:
[0129] When a fault occurs, the value in D240 is transferred to D0.
