智能热量表设计

摘要

改革开放以来，我国房地产业发展迅速，物业管理现已成为一个独立的产业。随着物业管理现代化水平日益提高，迫切要求物业管理部门对业主提供高质量的

服务及合理的收费。尤其是资源的使用要有精确的计量方法，方便的查阅手段，按量收费。现在水、电、煤气均已分户装表，依量收费．唯有供暖仍采用平均收

费的方法。这种方法因用户实际消费的热源不同，无形中就产生了不合理的因素，经常因此引起争议。建设部已明确指出，2005年用热也要分户计量，这样既可

减少物业部门与用户之间的争议，也使供热部门的生产效率及时体现。

智能热量表又称智能热表、智能能量表或智能暖气表，常安装在锅炉房或用

热点的出入口，主要用于监测和计量用热点热量消耗。本文设计了一种可以联网

进行集中管理和控制的微功耗热量表，3．6V锂电池供电可使本表正常工作6年

以上；操作简单，功能齐全。实现了智能热量表功能：累积热量计量及显示；供

／回水温度、温差测量及显示；累积流量计量及显示；流量测量及显示；日历时

钟功能；键盘控制；自诊断及故障显示、报警功能，当热量表出现故障或超限，有自动报警功能。

该智能热量表是户内型计量采暖用户消耗(即使用)的热量，以此为依据，在

用户采暖系统的分户计量中，按使用的热量收费，使供暖收费更趋于合理。设计

中采用涡轮流量计，带动微型电机，作为测速发电机，用其发的电压高低反映流

速信号，并根据管路口径与时间等参数计算出流量。在进水口和出水口各安装一

个温度测量传感器，计算出温差，再由流量与温差的参数计算出消耗的热量值，供热部门可通过现场或远距离遥测抄表收取热量使用费。也可由智能热量表本身

或远距离通讯指令，实现停止供热。

The Design of an Intelligence Calorimeter

Abstract

Since reform and opening up, China's rapid real estate development, property management has become an independent industry. With property management modernization level increasing urgently require property owners to the management to provide quality service and reasonable charges. In particular, the use of resources is to have accurate measurement methods and convenient means of access, according to the volume charges. Now they have water, electricity and gas have been splitting chart, according to the volume charges.

Only heating is averaging method. This means the user actual consumption of heat, in effect creating an unreasonable factors, it often controversial. Construction has clearly pointed out that 2005 also used thermal household metering, This would reduce the property sector and the dispute between the users and also heating efficiency of the production sector reflected in a timely manner. Intelligent Heat Meter also known as smart heat meter, or Intelligent Energy Intelligent Heating Table Table, often installed in the boiler room or a hot import and export, mainly to be used for monitoring and measuring using hot heat consumption. This paper designed a centralized network management and control of micro-power consumption calorimeter, 3.6V lithium batteries can power the table normal work more than six years; simple, complete functions. Heat Meter, an intelligent functions : accumulated heat measurement and display; For / return water temperature, temperature measurement and display; cumulative flow measurement and display; flow measurement and display; Calendar Clock function; Keyboard control; Self-diagnosis and fault, Alarm function, when the Heat Meter failure or overloaded, automatic alarm function. Heat Meter is the smart-metering indoor heating user consumption (that is, the use of) the calories, as a result, Heating System users in the household metering, by the use of heat charges, heating charges tends to be more reasonable. Design turbine flowmeter used to stimulate micro-motors, generators, as guns, the use of their high or low voltage signals reflect velocity, and according to the pipe diameter and time parameters, such as

flow rate calculat e d. In the inlet and outlet of the

installation of a temperature sensor, the calculated temperature, by the flow and temperature parameters of the calculated energy consumption value. Heating sector through on-site or remote meter reading collected telemetry heat toll. Tables may also be the smart long-distance communication itself or instructions, achieving a cessation of heating.
