地平式激光跟踪发射系统为保证其光路洁净，须进行正压防尘处理。针对外购空气净化设备仅能采用手动风速调节，不能实现计算机远程控制的不足，研发了空气净化设备数字化调速控制系统，以实现对空气净化装置的远程控制与状态监测。本设计采用光电隔离单相交流调压模块实现对风机的驱动，采用霍尔电流传感器实现对风机的电流测量，并采用内部集成A/D转换器和D/A转换器的单片机通过RS422总线接收控制指令，完成对调压模块的输出功率控制和风机电流的实时采集。本系统设计简洁、控制方便、运行可靠、易于维护，实现了设备管理计算机对空气净化设备风速的远程控制。

Horizon emitting laser tracking system to ensure its optical path cleaning, shall be positive dust treatment. For the lack of air purification equipment purchased only with manual speed adjustment and the remote control of a computer can not be achieved, we have developed an air purification equipment digital speed control system to achieve the remote control and status monitoring of air purification device. The design uses a optically isolated single-phase AC voltage regulator module for fan drive,uses a Hall current sensors to achieve the fan current measurement,and uses a microcontroller, which integrates a A/D converter and a D/A converter, to receive the control command via the RS422 bus, to complete the output power control of voltage regulator module, and to realize the real-time collection of fan’ s current. The system is designed to be simple, easy to control, reliable to operate and easy to maintain and realizes the remote control of a device management computer on the wind speed of air purification equipment.
