摘　　要：利用C8051F005单片机作为微处理器及其内部集成的ADC,设计了一种基于RTX51嵌入式多任务实时操作系统的多路数据采集系统。在RTX5l Tiny的管理下系统不仅可实现多任务并行执行,而且能对每个任务做出实时响应。该系统具有硬件结构简单、容易实现和成本低廉等特点,可用于多种工况环境下的各种电信号,温度、压力等物理量的采集及显示,其稳定性、精确性均能满足要求。Based on ADC subsystem integrated in C8051F005 chip, a kind of muhichannel data ac- quisition system based on RTX51 multitask real -time operating system was designed, which acted as the microcomputer. Under the management of RTXS1 Tiny, the system can not only perform multiple tasks at the same time, but also make real - time response for each task. The hardware of the system is simple, and it can be easily realized. It can be used to acquire, transform and display physical quantity such as voltage, temperature and pressure in kinds of industrial environment, the stability and precision of the measurement instrument are enough to meet the requirements.
