矿用无线雷达物位传感器设计

Design of mine-used wireless radar material level sensor

针对目前煤仓煤位监测系统中的雷达物位传感器存在的设置、维护、布线困难,维护成本高等问题,设计了一种矿用无线雷达物位传感器。该传感器采用集成无线射频模块的ESP8266单片机作为核心处理模块、雷达探头作为传感单元,能够在WiFi网络覆盖的环境中接入WiFi网络,在没有WiFi网络覆盖的环境中作为无线接入点来建立WiFi网络,建立Web服务与移动设备通信,以进行数据传输与传感器配置,还可通过RS485总线与现有煤仓煤位监测系统的矿用信息采集站连接,应用灵活。

For problems of difficult setting,maintenance and wiring and high maintenance cost of radar material level sensor in existing coal bunker material level monitoring system,a mine-used wireless radar material level sensor was designed.The sensor takes ESP8266 single chip microcomputer with a wireless radio frequency module as a core processor and a radar sensor as sensing unit.In an environment with WiFi network coverage,the sensor can be directly connected to the WiFi network.In an environment without WiFi network coverage,the sensor can be used as a wireless access point to establish a WiFi network.The sensor can provide web services to communicate with mobile devices for data transmission and sensor configuration.Meanwhile,the sensor can access mine-used information collection station in existing coal bunker material level monitoring system with a flexible application.
