摘要
介绍了一种能测试α-Fe2O3气敏元件参数的测试系统。该系统由上位机（PC）、下位机和测试箱3部分组成。下位机以80C552单片机为核心，以RAM62256（32K）作为数据存储器，MAX232芯片完成上下位机的串行通讯，实现对多个测试箱的监控。并给出了测试系统的硬件结构和工作原理，以及上位机软件系统框图。同时对该测试系统的优点进行了讨论。
The test system which can detect parameters of the α-Fe2O3 gas sensor is introduced. The system consists of computer-above (PC) and computer-below and testing-box. The system with computer-below based on 80C552 (CPU), RAM62256 (32K) used as the data memory and MAX232 used as serial communication can monitor many testing-boxes at the same time. The hardware structure and operating principle of the test system and the software flow chart of computer-above were chiefly recommended in this paper. At the same time, the advantages of this system were discussed.
