[Abstract]:With the improvement of people's living standards, the number of high-rise buildings is increasing, and the demand for elevator is becoming more and more extensive. The elevator monitoring system has been paid more and more attention by the manufacturers and users. In the case of Internet technology and high speed development of communication technology, the elevator monitoring system is not limited to fixed. The computer monitoring center is connected to the field bus by PC to achieve monitoring. Remote monitoring and real-time monitoring can guarantee the better access to information and fault of the elevator. On this basis, the elevator remote monitoring system is proposed. The function of the elevator remote monitoring system is the maintenance personnel, the manufacturer's power to run in the large residential area. The ladder is monitored remotely, and the elevator running state data and fault information are obtained, so as to detect faults in time, analyze and remove faults.
According to the actual demand of the elevator remote monitoring system, this paper analyzes the existing problems of the communication system, and combines the CAN bus technology and the industrial Ethernet technology, and puts forward the overall scheme of the communication system. This scheme mainly needs to realize the function of the CAN bus access to Internet.
In this paper, the hardware system is built with the LPC2368 microcontroller and the CAN communication module and the Ethernet control module. Then, the system software communication is designed in detail. The main realization of the underlying device driver, the implementation of the TCP/IP protocol, and the establishment of a complete data path. When the heartbeat is broken, the reliability of the communication system is maintained. Finally, the elevator acquisition equipment is connected to the Internet through the CAN bus. The data center on the Internet realizes the access to the elevator acquisition equipment through the system, and achieves the purpose of two-way communication.
