在工业、工程、生产车间等部门，尤其是在对信息实时性能要求较高或者恶劣的数据采集环境下，冗余数据采集系统具有十分重要的作用，它可以提高系统的可靠性和稳定性。设计实现了冗余数据采集系统的设计，可以实现在主数据采集系统的AD出错、单片机出错和掉电等情况下，副数据采集系统主动接替主数据采集系统工作。经测试可以应用于在对数据采集频率要求不高的工业控制中，保证数据采集系统持续稳定的运行，具有一定的实用价值。

In the industry,engineering,production workshop and other departments,especial y in the high requirement of real-time information or bad data acquisition environment,the redundant data acquisition system has a very important role,it can improve the reliability and stability of the system. The design has realized the designment of redundant data acquisition system.The system can achieve the functions as follows:When the fault of AT89S52 and ADC0809 appears and the power of system is cut off,the deputy data acquisition can take over the primary data col ection system to work automatical y.Under the condition of low frequency of data collection,the design can guarantee completely that the data acquisition can operate continuously and steadily,and it has a certain use value.
