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。 Using single chip and wireless module technology, a downhole wireless positioning device is designed. The design to STC89C52 microcontroller as the control center, with NRF24L01 wireless transceiver chip transmitting and receiving identification number, transmitted to the monitoring center through the data transmission line, the location information is displayed. Experiments show that the positioner has the advantages of simple equipment, low cost, convenient implementation, high reliability, high precision and high sensitivity, and can adapt to the harsh underground environment and work steadily for a long time, and the light display and other repercussions. Preliminary assessment of the trapped staff direction, search and rescue positioning function.
