Abstract

The invention provides a system for metering and charging a construction heat and carrying out energy-saving monitoring by the Internet of Things, belonging to the technical field of construction heat metering and charging, and energy-saving control. For the purpose of collecting and transmitting information, such as a heat supply process, heat supply equipment and heat supply users by using the technology of the Internet of Things, the system detects the user heat supply service quality in real time, monitors the heat using condition of users in real time, and optimizes a decision to control in an energy-saving manner according to the collected information. The output ends of a temperature sensor, a pressure sensor and a flow sensor are respectively connected with an information collection input end of a data collector. Each data collector for metering a heat supply user side is used for transmitting the information to a substation monitoring center of corresponding substation in a GPRS (General Packet Radio Service) RTU (Remote Terminal Unit) manner. The substation monitoring center is used for conditioning the working state of a valve / frequency converter by a controller and is communicated with a heat supply network monitoring center by Internet / Ethernet network. The heat supply load is forecast by using a signal processing technology and the energy conservation of a heat supply system is realized by controlling according to a forecasting result.

Description

technical field [0001] The invention relates to an Internet of Things system for building heating metering and charging and energy-saving monitoring, and belongs to the technical field of building heating metering and energy-saving control. Background technique [0002] Buildings are one of the most important areas for energy conservation and emission reduction in response to climate change. Heating energy consumption in cities and towns in northern my country accounts for 45% of the total energy consumption of urban buildings in the country, and is the largest component of building energy consumption. 1 to 1.5 times the energy consumption, it is imperative to save energy in building heating. At present, the domestic heating system technology is backward, lack of testing equipment, or the degree of automation of the testing equipment is not high, and the information monitoring of the generation, distribution, transmission, exchange and application of heat energy in the heatin...
