摘　　要：通过分析电子压力计的工作原理，提出了一套由98单片机为核心的高精度电子压力计校验系统的组成方案，其中为满足高精度频率测试的要求，开发了98单片机HSI口定时计数功能；为满足电源切换和数据传输的要求，开发和利用了HSO高速输出口和RS232通讯口，并详细地给出了它的汇编程序框图。实际使用表明，由98单片机组成的信号接口，结构简单，功能强，适用面广，是高精度电子压力计校验接口的理想测量器件。This paper puts forward a calibration system of electronic pressure meter with 98 microcomputer. In order to complete the accurate measurement of frequency,the HSI timer function of 98 microcomputer is developed.To meet cut off power source and data transmisslon,HSO output and RS 232 communication of 98 microcomputer is exploited. In addition,the program flow diagram about 98 microcomputer is given in detail. Practical use shows that the signal interface composed of 98 microcomputer is simple in structure and with that of reliable functions and wide applicatlons,thus is an ideal measurement device of the ca1ibration interface of high accurate electronic pressure meter. It is practicable that 98 micromcomputer is used in a calibration system of e1ectronic pressure meter.
