面向关门力自适应控制系统的内外压差实时监测系统

Real-time Monitoring of Internal and External Pressure Difference Oriented to Adaptive Control System of Door Closing Force

设计了一种内外压差实时监测系统为关门力自适应控制提供数据基础。采集到的地铁门扇内外的气压数据经过协调器传输给上位机进行处理显示以及存入数据库。采用2.4GHz IEEE 802.15.4协议的ZigBee无线通信技术,使得数据传输更加安全稳定,降低了系统的成本和功耗。经实验测试,该系统能够实现对地铁门扇内外气压数据的实时监控和储存,在地铁门系统安全稳定运行方面有重要意义。

This paper designed a real-time monitoring system for internal force and external pressure difference, and provided a database for automatic control of closing force. The collected air pressure data inside and outside the door fan of metro are transmitted to the upper computer by the coordinator for processing and display and stored in the database. The ZigBee wireless communication technology adopted the 2.4 GHz IEEE 802.15.4 protocol to safeguard and secure data transmission and reduce system cost and power consumption. This system can monitor and store data of air pressure inside and outside the door fan in real time.
