[Abstract]:Nowadays, with the rapid growth of the number of urban cars and the serious shortage of parking facilities, the problem of parking difficulties is becoming increasingly prominent, and the shortage of urban land resources exacerbates the problem of parking difficulties. The application of stereoscopic garage can make this problem to be alleviated or even solved. It is one of the effective measures to solve the problem of parking difficulty because it can make full use of very little land area, exert great spatial advantages and place vehicles to the greatest extent. Therefore, in this paper, the research and design of intelligent three-dimensional garage control system based on S7-1200PLC, touch screen and upper computer is carried out. This paper first analyzes the research and application status and development trend of domestic and foreign stereoscopic garage, and then analyzes the functional requirements and control requirements of intelligent stereoscopic garage control system. The overall design of the intelligent stereoscopic garage control system is completed. At the same time, the in-situ standby access strategy and the parking space scheduling optimization control design are adopted to realize the high efficiency and energy saving of the stereoscopic garage from the aspects of access capacity and action efficiency. The hardware part, according to the function requirement and the control requirement analysis, mainly carries on the hardware design to the detection part, the control part and the execution part. The detection part uses photoelectric switch, proximity switch, limit switch and other sensors to detect and collect the state and operation of the stereoscopic garage, complete the circuit design of the signal input and output, and take S7-1200 PLC as the main controller in the control part. The signal data transmitted from the detection part is processed, and the PROFINET communication is established by connecting the touch screen and the upper computer through Ethernet. The data is transmitted to the touch screen and the upper computer to display, At the same time, it also receives the control instructions from the touch screen and the upper computer. The executive part is composed of a parking lift motor, a parking space transverse motor, a safety hook and a safety lever, which mainly completes the circuit design of the motor control module. In the software part, the software function module is analyzed, combined with hardware design, the program design of sensor signal detection, reset, parking space scheduling optimization control, automatic control, manual control and other functional modules is completed. According to the control flow chart, the programming of each module is realized in turn. According to the actual functional requirements, the automatic control interface and the manual control interface are designed for the software design of the touch-screen touch control system, so as to realize the on-site operation of the three-dimensional garage by the user or operator. According to the software design of the monitoring system of the upper computer and the PLC control program, the real-time monitoring interface of the state of the stereoscopic garage is designed in order to realize the remote monitoring function of the state and operation of the stereoscopic garage. Finally, the intelligent three-dimensional garage control system is simulated and debugged. After many modifications and improvements, the final debugging results show that the system runs stably and reliably, the control interface is simple and friendly, and the monitoring system can monitor the state of the garage in real time, and achieve the expected design goal and effect. The intelligent three-dimensional garage control system designed in this paper has played a positive role in alleviating the problem of parking difficulties, and has certain practical and practical significance.
