基于CC2420的煤矿井下采掘设备无线数据采集装置

Wireless Data Collecting Device of Underground Mining Equipments Based on CC2420

针对位置经常随机移动的采掘设备通过单机采集方式采集数据而存在操作不方便的问题,提出了一种基于CC2420的无线数据采集装置的设计方案。该装置中的数据采集模块利用采掘设备电控箱中的PLC完成采掘设备工作状态、工作参数等数据的采集任务,并将处理后的数据通过RS485串口发送给无线发送器,无线发送器通过射频模块CC2420将数据发送到无线接收器,无线接收器将接收到的数据先存储到缓存中,缓存满时,写入U盘。实际应用表明,该装置能够方便地采集位置随机移动的采掘设备的数据。

In view of problem of inconvenient operation that mining equipments whose position move randomly use single machine collecting mode to collect data, the paper proposed a design scheme of wireless data collecting device based on CC2420. Data collecting module in the device collects data of working state and working parameters of mining equipments by use of PLC in electric cabinet of mining equipments and sends the processed data to wireless transmitter through RS485 serial port; the wireless transmitter sends the data to wireless receiver through radio frequency module CC2420 and the received data are stored in buffer by the wireless receiver, and the data is written in U disk when the buffer is full. The actual application showed that the device can collect data of the mining equipments conveniently.
