The device uses the PLC 5 as the control system core of the dodging-free three-dimensional parking device and plays a role in collecting information of other equipment, processing and transmitting the information. The designed functions of the system are required to be based on the standard of realizing the stable, effective and safe operation of the avoidance-free three-dimensional parking device. The main functions of the PLC controller 5 are: effectively receiving a vehicle storing (fetching) signal; detecting whether the parking (taking) environment is safe or not; controlling the motor to operate to store (fetch) the vehicle; and controlling the recovery of the unexpected interruption. Therefore, the software program of the control system can be divided into two parts, namely a normal vehicle storing (fetching) operation program part, when special conditions such as no obstacles, equipment faults, power failure and the like occur, the device can automatically complete vehicle storing (fetching) operation, and an accidental interruption recovery part, when special conditions such as obstacles, equipment faults, power failure and the like occur, the control system can automatically interrupt the current operation, the hardware system can ensure that the vehicle and the device safely stop running, and after the special conditions are relieved, the device automatically recovers the running process before interruption and continues vehicle storing (fetching) operation. When the infrared sensor receives a parking signal, the ultrasonic sensor is started automatically to continuously detect whether obstacles exist in the range of 30cm around, if so, the motor stops running to keep the current position of the vehicle carrying board unchanged, the safety indicator lamp continuously emits light, and after the obstacles are removed, the motor automatically runs to maintain the original working state to complete the current operation. Referring to fig. 10, the PLC controller 5 is further equipped with a safety warning light, a limit switch, a motor, and the like, and adopts an encoder to acquire an accurate control system of the output speed of the motor.

When the PLC works, the PLC controller 5 is started through a key or wireless remote control. The PLC controller 5 controls the transverse moving motor 602 to be started, the transverse moving motor 602 drives the gear 604 to rotate, and the moving box 6, the lifting rotary column 2 and the vehicle carrying plate 1 are driven to move along the guide rail 301. The purpose of this motion is to reduce the follow-up car carrying board 1 and rotate the occupation of in-process to the space above the parking stall to realize the intensive placing of device, make space utilization efficiency obtain great promotion. When the vehicle carrying board 1 reaches a designated position, the PLC 5 controls the transverse moving motor 602 to stop, the rotating motor 603 is started, and the lifting rotary column 2 and the vehicle carrying board 1 are driven to rotate by a designated angle through the rotating transmission device 605. The rotating angle can be adjusted according to different parking space types, so that various parking conditions in the community can be flexibly adapted. When the vehicle carrying board 1 reaches the designated position, the PLC controller 5 controls the rotating motor 603 to stop, the lifting motor I7 and the lifting motor II 8 are started, the lifting motor I7 drives the chain wheel 2022 to rotate through the lifting transmission device, and the vehicle carrying board 1 descends through the lifting chain. The double-upright-column lifting vehicle carrying plate is adopted, and the stress is balanced and stable. The lifting motor II 8 drives the lifting screw rod 404 to assist the vehicle carrying plate 1 to descend through the commutator. Support force is provided for the vehicle carrying plate 1, so that the stress of the vehicle carrying plate 1 is more balanced. After the vehicle carrying plate 1 is lowered to the ground, a vehicle owner drives the vehicle on or off the vehicle carrying plate 1. After the automobile is driven, the sensor confirms that the automobile is parked at a proper position, and the parking device repeats the previous actions in the reverse order, so that the resetting of the automobile carrying plate 1 is realized, and the final parking of the automobile is finished.

In this embodiment, the traverse motor 602, the rotating motor 603, the lifting motor i 7 and the lifting motor ii 8 are all speed reduction motors, and a worm gear speed reduction device is included in a speed reducer of the motors. By utilizing the self-locking characteristic of the worm gear motor and the self-locking characteristic of the lead screw, the falling caused by the accidental translation of the vehicle carrying board 1 caused by external force, the accidental rotation of the upright post I201 and the sliding of the chain wheel 2022 caused by accidental power failure can be prevented. The anti-falling device is embedded in the lifter, so that the anti-falling device can be locked in a short time when the phenomenon of free falling of the vehicle carrying plate occurs in the worst condition of failure of the upper turbine gear device, breakage or separation of the chain, and the occurrence of dangerous accidents is prevented. The lower end of the lifting screw rod 404 is sleeved with a lifting sleeve 4041. Referring to fig. 5, the universal wheel 405 is connected to the lower end of the lifting screw 404, and the lifting sleeve 4041 can be driven by a motor to realize the lifting movement of the nested universal wheel 405. When the sleeve 4041 is raised and lowered, it may be supported for rotation by the universal wheels 405. When the lifting sleeve 4041 is lowered, a high-load long-time parking state can be realized.

Referring to fig. 13, 14, 15 and 16, it can be seen from simulation analysis that the stress does not reach the allowable stress of the material, and the maximum displacement occurs at the corner portion farthest from the supporting point, so as to meet the use requirement.

It should be noted that in this embodiment, the PLC controller 5 adopts S7-200 PLCCPU226 manufactured by siemens, and is responsible for communicating with an upper computer, controlling on/off of a frequency converter, receiving a sensor signal, displaying a current working state, and the like. The system has the characteristics of high reliability, rich instruction sets and expansion modules, convenience in operation, rich built-in integrated functions, capability of real-time communication and the like, and is easy for a user to learn and master. The CPU226 model has 24 input ports, 16 output ports and 7 maximum expansion modules, which are enough to meet the requirements of the ports of the control system of the mini-parking device.

Because the required motor may need load starting, the required starting torque is large, the starting current is small, and finally three motors shown in table 1 are selected by combining the calculated required power, torque and other parameters. The lifting motor and the rotating motor have the characteristics of large overload capacity, high mechanical strength, compact structure, adjustable braking torque, convenient control, use and maintenance and the like, and are suitable for short-time or intermittent operation, frequent starting and braking, and sometimes overload lifting and translation on metallurgical equipment and driving and braking on a lifting mechanism. Because the translation motor needs to control the screw drive, an ECMA-G0613 motor manufactured by Taida corporation was selected. The three motors have the functions of load starting, forward and reverse rotation operation and the like, and the requirements of the device can be completely met.
