技术领域technical field
本实用新型涉及热能计量表信号传输设备领域，具体涉及一种热能计量表信号传输装置。The utility model relates to the field of heat energy meter signal transmission equipment, in particular to a heat energy meter signal transmission device.
背景技术Background technique
上个世纪40年代，丹麦人梅得斯研制出了一种用于供热系统的散热器恒温阀，该恒温阀主要通过传感器来控制阀门的大小以调节室内的温度，以达到舒适的目的，这算得上是热能表的雏形。到了20世纪70年代欧洲各国纷纷开展节能运动，一些相关的节能设备也不断被研制出来。热能表就是在这个大背景下被提出来发展起来的。1964年德国开始热能表的研制工作。最初的热能表为机械式，70年代后出现了电子热能表，而电子热能表经历了模拟积分式、电子数字积分式，到智能式的发展过程。直到上个世纪九十年代，户用热能表基本定型，设计趋于一致。经过几十年的发展，国外热能表的发展已经比较完善。从热能表的研制、热能表的标准制定、到设备的标定检测以及最后的投入使用，国外很多国家都有自己一套完备的方案。In the 1940s, the Danish Medes developed a radiator thermostatic valve for heating systems. The thermostatic valve mainly uses sensors to control the size of the valve to adjust the indoor temperature to achieve comfort. This can be regarded as the prototype of the heat meter. In the 1970s, European countries launched energy-saving campaigns one after another, and some related energy-saving equipment were continuously developed. The heat meter was proposed and developed under this background. In 1964, Germany started the research and development of heat meters. The original thermal energy meter was mechanical. After the 1970s, electronic thermal energy meters appeared, and electronic thermal energy meters experienced the development process of analog integral type, electronic digital integral type, and intelligent type. Until the 1990s, household heat meters were basically finalized and their designs tended to be consistent. After decades of development, the development of foreign heat meters has been relatively perfect. From the development of heat meters, the standard formulation of heat meters, to the calibration and testing of equipment, and finally put into use, many foreign countries have their own complete plans.
我国1989年才开始关注供热的计量、收费问题，并于1990年将热能表专用电路研发列入国家科技攻关计划。之后，一些中小企业也开始自发的进行户用型热能表的研究工作。直至1997年，欧洲热能表标准EN-1434发布后，我国真正进入热能表的研制开发工作。近几年来, 随着供热面积的不断扩大, 按面积收费的管理体制与市场经济经营机制越来越不相适应。当下的热能计量表多采用电线连接的方式传输信号，线路复杂，占用空间过大，传输速度慢且不稳定。It was only in 1989 that my country began to pay attention to the measurement and charging of heat supply, and in 1990, the research and development of special circuits for heat meters was included in the national scientific and technological research plan. Afterwards, some small and medium-sized enterprises also began to conduct research on household heat meters spontaneously. Until 1997, after the release of the European heat meter standard EN-1434, my country really entered the research and development of heat meters. In recent years, with the continuous expansion of the heating area, the management system of charging by area is increasingly incompatible with the market economic operation mechanism. The current thermal energy meters mostly use wires to transmit signals, which are complex, take up too much space, and have slow and unstable transmission speeds.
