针对矿井下噪声带来的语音交流困扰和各种设备的电磁干扰,设计出一种基于标准1W LED矿工灯的无线对讲系统。由于系统要兼具照明和通信,在发射端设计了具有切换功能的照明调制驱动电路。通过对系统照明和通信性能的仿真分析,在满足标准照度和保证通信误码率10-6条件下,可实现井下照明和通信双重功能。 Aimed at the problems of voice communication and interference from various devices under the mine noise, a wireless intercom system based on the standard 1W LED mining lamp was designed. As the system should be both lighting and communications, the transmitter designed with a switching function of the lighting modulation driver circuit. Through the simulation analysis of system lighting and communication performance, under the conditions of meeting the standard illumination and ensuring the communication bit error rate of 10-6, the dual functions of underground lighting and communication can be realized.
