摘　　要：原有的化学激光器测控系统不仅外形庞大,而且数据采集不便、精度不高,采集点添加困难。为此,设计了一种基于PIC单片机的智能数据采集系统,主要由远程控制系统和数据采集模块组成。其能够远程控制激光器上各采集模块的运行,实时采集与存储压力或温度数据,并将数据无线传输到控制系统上。采集模块自带电源,模块化设计,扩展性强,可直接与传感器相连无需修改,最多可扩展65 535个。系统主要用于化学激光器中的压力测量,同时还适用于工业控制、科学研究等需要大量传感器的地方。Previous chemical laser measurement and control system not only has huge profile, but also is inconvenient to colleet data,low precision, and difficult to add more data acquisition points. So an intelligent data transmission system based on PIC MCU is designed, whieh is composed of remote control system and data acquisition module. This system can remotely control operation of data acquisition modules in the laser, real-timely collect and storage data of pressure or temperature, and can also wirelessly transmit data to control system. The data collection module adopts modular design, with self-powered, good sealability, which can be connected to sensors directly, without considering any changes and can be extended up to 65535. This system is mainly used in pressure measurement of chemical lasers, and can also be applied to industrial control, scientific research where large numbers of sensors are needed.
