供热系统集中器的智能控制终端设计与实现

为了解决目前城市供热系统主控中心单一控制方式造成的工作量大、控制不稳定、上传数据延迟等问题,提出了一种以楼栋集中器为控制对象的智能控制终端.该终端主要由中央处理器、IC卡读写模块、万年历时钟模块、数据存储比对模块、短信提醒模块、声光提醒模块组成.采用集散控制方式,把供热系统主控中心的单一控制权分散到每个楼栋,用户持IC卡到主控中心充值购热,然后在居民楼的控制终端刷卡来控制自家热量的使用状态,实现了供热管理的集中操作、分散控制、分级管理和灵活组态.

Design and Implementation of Intelligent Control Terminal of Concentrator in Heating Supply System

In present city heating supply system,to solve the problems caused by single control mode of main control center such as huge workload,unstable control,unload data delay and so on,an intelligent control terminal which regards building concentrator as the control object is proposed.The terminal is composed of the central processor,IC card reading & writing module,calendar clock module,data storage and comparison module,SMS reminding module,light and sound reminding module.Adopting distributed control method,single control mode of master control center can be dispersed to every building.Users can hold IC cards to the main control center to purchase heat energy and recharge cards,then slotting the cards in building control terminal to control their heat energy usage,which realizes the centralized operation,decentralized control,hierarchical management and flexible configuration of heating supply management.
