【摘要】：我国供热系统一直以来按照面积进行收费，这种方式存在能源浪费、收费不合理等问题。对热量进行计量，通过热量商品化、货币化，促使用户节能是供热体制改革的关键环节。目前多数热量计量仪表采用人工抄表，效率低、入户难。本文设计了可对室内热量计量、无需人工抄表，并可进行个性化节能控制的基于以太网技术的热量计量系统。 本设计由热量表、手持设备、集中抄表器、供热监控管理中心四部分组成。热量表通过时间数字转换器并结合铂电阻和超声波传感器测量温度及流量，利用MSP430单片机完成热量值的计算及热量的节能控制；热量表之间通过ZigBee无线通信模块进行短距离通信，并将数据经多级转发到集中抄表器。集中抄表器选用CC2530射频芯片控制，采用以太网控制器ENC28J60实现网络连接，将集中抄表器中的数据传输至供热监控管理中心，实现了供热系统中数据的远程传输及无线抄表。用户可通过手持设备个性化设定各房间温度。供热监控管理中心通过系统上位机软件，对热量表进行监控。 本设计具有计量准确、抄表方便、收费合理等特点；可以为用户提供便捷的收费服务；用户可以自主控制用热量，，提高用热舒适度和用热合理性；同时方便供热部门对供热系统进行智能化管理。本系统满足国家节能减排的要求，具有广阔的应用前景及市场。
[Abstract]:The heating system of our country has been charging according to the area for a long time, which has some problems such as energy waste, unreasonable charge and so on. The key link of heating system reform is to measure heat quantity, to promote energy saving by means of heat commercialization and monetization. At present, most heat metering instruments use manual meter reading, the efficiency is low, and it is difficult to enter the house. In this paper, a heat metering system based on Ethernet technology is designed, which can measure indoor heat without manual meter reading, and can carry out individualized energy saving control. This design consists of four parts: heat meter, handheld device, central meter reader and heating monitoring management center. Through the time digital converter, combined with platinum resistance and ultrasonic sensor to measure the temperature and flow rate, MSP430 single chip microcomputer is used to calculate the heat value and control the energy saving. The heat meter communicates in short distance through ZigBee wireless communication module, and the data is transmitted to the central meter reader by multistage. The CC2530 RF chip is used to control the central meter reader, and the Ethernet controller ENC28J60 is used to realize the network connection. The data in the central meter reader is transmitted to the heating monitoring management center. The remote data transmission and wireless meter reading in the heating system are realized. The user can personalize the room temperature through the handheld device. The heating monitoring and management center monitors the heat meter through the software of the upper computer. At the same time, it is convenient for the heating department to manage the heating system intelligently. The system meets the requirements of national energy saving and emission reduction, and has a broad application prospect and market.
