摘　　要：根据油田员工安全信息系统建设对员工定位器的功能需要,设计了GSM模块和GPS模块,作为信息中心与定位器间信息交互的硬件部件。在系统控制核心上采用双处理器管理模式,实现系统的硬实时功能;在双处理器系统设计中,利用双口存储器构建紧密耦合多处理器体系结构,提高双MCU之间通信能力;设计系统LCD显示器部件;设计两个MCU之间异步通信的PETRI网模型并据此实现通信关键算法,确保了通信的正确性。According to the function need required by the locator in the fields employee security information system the GSM module and GPS module are designed as the hardware part for the message interaction between the information center and the locator. The dual processor management pattern as the system control ore is adopted to realize the sturdy real time function in the design and the processor system by use of the dual-port memory the tight bond multi- processor system structure is made. It enhances the traffic capacity between the double MCUs, The LCD is also designed for the system to ensure the reliability of the communication.
