一种预付费式供热计费与监控装置

A Pre-paid Cost Calculation Equipment of Heat Supply and Supervising

针对供热系统中的计费与监控问题,本文提出了一种以微控器作为计控单元,引入IC卡技术对资源供应进行管理,能通过两个RS-232标准方便地与计算机、数传电台、智能仪表等串行接口,从而构成实时有序的计费、监控管理系统的装置。由此和主控计算机及无线数传电台构成的无线网络监控系统,可以大大提高了对供热系统的运行管理水平,确保了企业的直接经济效益。

Aiming at the problems of the controlling and energy cost allocation of centralized heating, the thesis provided a conclusion of better control and toll models in the heating system, which used a microcontroller to calculate the cost and introduced the new IC card technique to supervise the heating system. This model can effectively supervise and control the heating system of our power factory throughout tow RS-232 interfaces which are conveniently connected with computer and intelligent instrument. This new structure of heat metering and toll device is based on data ration station and wireless network, which has the favorable effect to improve heat measure and supervising system to insure the economical benefit.
