摘　　要：根据ＺＲＪ型热量流量智能积算仪使用中存在的问题，从硬件和软件两个方面对其进行了改进。在硬件中，对抗干扰和掉电保护电路、铂电阻测温电路、Ｄ／Ａ输出电路作了改进，使其功能更完善；在软件方面，增设了与电磁流量计、孔板流量计配套的相应软件及打印驱动、控制系统，还增设了数据表决程序、软件自诊断程序等，使软件的功能和容量得到进一步扩充。According to the problem exiqting in the use of Model ZRJ intelligent heatand flow integrating meters,the hardware and the software were improved.The anti-dis-turbance and leak protection circuit,the platinum resistance measuring temperature circuitand the D/A output circuit in the hardware were modified to improve their functions. Asfor the software,the corresponding software completing with electromagnetic flowmeterand orifice meter,and print drive and control system were added,including data voting pro-gram and software self-diagnotqtic program etc,to expand the functions and volume of soft-ware.
