Heating meter metering device based on ADuC812 single-chip microcomputer

Abstract

The invention discloses a heating meter metering device based on an ADuC812 single-chip microcomputer. The heating meter metering device comprises a signal detection circuit, an ADuC812 single-chip microcomputer power supply, a crystal oscillation circuit, a reset circuit, a keyboard display interface circuit and a GPRS wireless communication module. The signal detection circuit comprises a water inlet pipe temperature detection circuit, a water outlet pipe temperature detection circuit, a Hall flow sensor, a first instrument amplifier and a second instrument amplifier. The Hall flow sensor is connected with an I / O input port of the ADuC812 single-chip microcomputer. A clock circuit is further connected on to the I / O input port of the ADuC812 single-chip microcomputer. A keyboard and a four-digit nixie tube display are connected onto the keyboard display interface circuit. The invention can achieve temperature control of separate houses and separate rooms, provides corresponding technical support for residential areas adopting intelligent heat supply and allows a resident to adjust the room temperature for different rooms as actually needed, thereby improving the living comfort and saving heating expenditure.

Description

technical field [0001] The invention belongs to the technical field of intelligent heating, and in particular relates to a metering device for a heating meter based on an ADuC812 single-chip microcomputer. Background technique [0002] With the development of science and technology, residential quarters are developing in the direction of digitalization and intelligence; in the heating pipe network system of residential buildings, "metering by household, temperature control by room, and charging by household" are gradually implemented, which is not only conducive to energy saving and consumption reduction , and can improve people's quality of life, is a development trend. However, the traditional heating system wastes more heat, cannot realize household control, and has not attracted the attention of the people. If a central heating system and a heating system controlled by households and rooms are installed in residential areas, residents can adjust the room temperature of ...
