摘　　要：介绍了单片机多路光强信号检测系统的研制．该系统采用8031单片机为微处理器，ADC0804实现A／D转换，4067作为模拟多路开关，根据需要可扩充输入通道数，能实现放大倍数的自动调节，并实现与PC机的通信，传输数据供其处理。Introduces the development of a singlechip microcomputer multichannel detection system of light intensity signal. In the system, an 8031 singlechip microcomputer is adopted. A/D conversion is achieved by ADC0804, and an analog multichannel switch by 4067. The number of input channels may be extended if necessary, and the amplification ratio controlled automatically. The system may also be applied to intercommunication with personal computers and transmitting data in data processing.
