摘　　要：根据当前化工、医疗、航空、航天等高科技领域对温度调节和控制的要求,设计了一套分布式温度控制和采集系统,给出了具体的硬件电路设计和系统软件实现,使用一线制数字温度传感器采集温度。与传统测温装置相比,具有结构简单,测温精度高、应用面广等特点。结合AT89S51单片机与PC机的通信机理,采用基于多线程的串行通信技术,扩展了和上位机的串行通信,实现远程监控,实现了对目标区域温度的自动实时监控、自动调节及智能报警功能。试验结果表明,整个系统不但成本低廉、而且使用和扩展方便,可广泛应用于人们日常生活、工农业生产和科学研究领域,为广泛深入应用提供了借鉴。According to the temperature regulation and control requirements in current chemical,medical,aviation,aero-space and other high-tech fields,a set of distributed temperature control and acquisition system was designed. The specific hard-ware circuit design and software implementation methods are given. A digital temperature sensor is used to collect temperature. Compared with the traditional temperature measurement device,it has more simple structure,higher temperature measurement precision,wider application rang,etc. In combination with AT89S51 and PC communication mechanism,the serial communica-tion based on multi-thread technology is adopted to extend the functions of serial communication with PC and remote monitoring, and achieve the real-time temperature automatic monitoring,automatic adjustment and intelligent alarm in object region. Experi-mental results show that the system has the characteristics of low cost,convenient application and extension,which can be wide-ly used in people＇s daily life,industry,agriculture and scientific research,and can provide a reference for the extensive applica-tion.
