煤矿井下小型无线定位器的设计

Design of Small Coal Mine Wireless Locator

利用单片机和无线模块技术,设计了一种井下小型无线定位装置。该设计以STC89C52单片机为控制核心,用NRF24L01无线收发器芯片发射接收标识号码,通过数据传输线传输到井上监控中心,将位置信息显示出来。实验表明,本定位器具有设备简单、成本低、实施方便,可靠性、精度和灵敏度高等特点,能适应井下恶劣环境并长期稳定工作,还有光显示等回响。初步判断被困人员的方向,实现搜救定位功能。

Microcontroller and wireless module technology, the design of a small underground wireless location device. The design microcontroller to stc89c52 to control core the nrf24101 wireless transceiver chip transmitter receiver identification number through a data transmission line to Inoue monitoring center, the location information is displayed. The experiments show that the present locator device is not only simple, low cost, easy to implement, and higher reliability, accuracy and sensitivity, can adapt to the harsh downhole environment and long-term stability, there is the optical display echoes.Determine the initial direction of the trapped workers, search and rescue positioning function.
