摘要
研制的基于滑动载波方式的电梯轿厢信息传输装置,采用磁耦合原理实现了电梯控制信息的非接触式传输,避免了传统方式中轿厢的随行电缆易疲劳破损的弊病。滑动载波装置的调制解调环节采用高集成度载波通信芯片ST7540完成载波信息的收发,装置的总线接口采用集成模块实现CAN-bus网络和UART设备之间的数据通信,磁耦合器的设计考虑了最佳功率传输。该装置具有零误码率的传输可靠性,对外无电波干扰的电磁兼容性,既能满足新装电梯的设计要求又方便对已安装的传统随行电缆通信方式进行升级改造等优点。
Elevator car information transmission device is demonstrated by utilizing the sliding carrier wave.This device has realized non-contact elevator control information transmission by taking advantages of magnetic coupling technique,which can notably reduce the wear and tear of the accompanying electric cable of traditional elevator cars.The modem module of the device utilizes a highly integrated carrier communication chip ST7540 as a transceiver of the carrier wave and the bus interface uses an integrated module to realize the data communication between the CAN bus network and the UART devices.The optimal power transmission is considered in the design of the magnetic coupler.Also,the device has the transmission reliability of zero error rate,electromagnetic compatibility of ambient radio interference rejection,and the benefit of both meeting the design criteria of new elevator and the convenience for the modification orupgrading of the communication mode of existing traditional electric cable.
