[Abstract]:On the basis of studying the present safety situation of aluminum alloy hydraulic lift, we make full use of the technological achievements of modern electronic information technology, computer technology, sensor measurement technology, etc. In this paper, a new generation of intelligent aluminum alloy hydraulic elevator safety monitoring system is developed. At the same time, a detailed system design scheme is given, and the hardware and software design of each data measurement system is introduced in detail. The system has the functions of real-time detection, control, alarm, data display, system reset and so on. The communication technology of RS-485 and CAN bus is adopted in the system, and the communication between each module is realized. The system has designed and realized the detection and display of the tilt state of the hydraulic elevator of aluminum alloy, the detection and display of the rising height, the detection and display of the weight carried by the lift platform, and the detection and display of the weight carried by the lift platform. If the system exceeds the rated value, the system will immediately start the alarm. And control aluminum alloy hydraulic lift stop operation. Firstly, the hardware circuit of the system is designed according to the demand. Through the comprehensive comparison of the main control chip, the single chip microcomputer of PIC series is selected as the control chip of the whole system. Then, C-51 language is used to write the whole control system. The C language has strong function, supports floating-point operation, and is easy to write, which is helpful to improve the system precision and operation ability. Then, the design flow of the main function module of the software is introduced. They are the main program, the angle, the height, the weight detection module program, the bus communication program and the display chip program. Finally, a series of software and hardware protection measures are adopted to improve the anti-interference ability of the system. Especially for the data obtained from the weight detection, the experimental data can be processed by using the linear neural network minimum mean square error intelligent algorithm, which can make the experimental data more accurate. Finally, through a period of operation, the whole system has completed all the required functions, running stably and reliably, and achieved the expected goal. The system improves the safety performance of aluminum alloy hydraulic lift and brings good social and economic benefits.
