[Abstract]:Combined with the actual situation of elevator control system at home and abroad, the elevator controller based on embedded system is studied in this paper. The embedded real-time operating system is applied to elevator control system, and the software and hardware of elevator controller are studied. The main contents of this paper are as follows: 1. Summarize and excavate the technical characteristics of the existing elevator control system, analyze the overall structure of the elevator control system, clarify the basic functions and principles of each part of the control system. The communication principle and realization method of the controller hardware are also given. 2. The embedded operating system is introduced as the controller kernel, and the hardware architecture is built. The hardware structure of elevator controller is mainly composed of micro CPU,OS and basic components. In this part, the construction process of hardware structure, the selection and comparison of communication lines, the principle of elevator dispatching and control and the external interface are discussed in detail. The hardware platform adopts AT91R M9200, and the overall design adopts two-layer board body. The detailed design method of the outer circuit is given, including Ethernet, Modem, CAN, I / O and external operation interface, among which the Ethernet part, the Modem part, the CAN part, the I / O part and the external operation interface are given in detail. The design of I / O part and external operating interface is one of the innovations in this paper. CPLD is used to control it and its role in the construction of hardware structure is studied. 3. The software platform of elevator control system is designed. Firstly, the whole structure of the software platform is discussed and designed, and then the software implementation of each component in Linux environment is studied, and the single ladder software control flow based on the elevator controller studied in this paper is given. The control task is divided and processed in detail, and the basic control task is realized by software programming. The simulation results show that the elevator controller designed in this paper has good logic control function. This provides a good basic idea for the future study of advanced intelligent control elevator. This paper studies and obtains the elevator controller model based on embedded system, which is of great benefit to the author's teaching work on elevator in the future.
