Heat metering information remote transmission system based on composite communication mode

Abstract

The invention discloses a heat metering information remote transmission system based on a composite communication mode. The heat metering information remote transmission system comprises a plurality of household calorimeters, collectors, concentrators and a heat supply management central server, wherein M-BUS communication modules of the household calorimeters are connected with M-BUS communication modules of the collectors and transmit data through M-BUS buses; power line carrier communication modules of the collectors are connected with power line carrier communication modules of the concentrators and transmit data through power lines; and wireless communication modules of the concentrators are in wireless connection with a wireless communication module of the heat supply management central server and transmit data through a wireless network. The heat metering information remote transmission system provided by the invention can promptly, accurately and safely realize heat metering information remote transmission at comprehensive low cost, and is suitable for centralized meter reading and charge management of calorimeters.

Description

technical field [0001] The invention relates to a remote transmission system of heat metering information, in particular to a remote transmission system of heat metering information based on a composite communication mode. Background technique [0002] With the widespread popularization of "one household, one meter" for heating metering, the number of customers applying for one household, one meter for urban and rural residents, enterprises and real estate development (property management) units has surged, and the charging method of heating units will change from simple The form of multiplying the heating area by the coefficient is changed to a composite accounting method, which has many accounting reference parameters, including the flow rate of hot water supply, the temperature difference between the incoming water and the return water, etc. Therefore, the data collection and monitoring of heat metering It becomes complicated, especially for some grass-roots heating units...

AI Technical Summary

Problems solved by technology

Wired remote meter reading refers to the use of wired communication from the heat supply management center to the user’s heat meters, which has a high reading rate, but it needs to lay lines, especially for buildings that have been built and have not reserved corresponding pipelines. Punching holes, high cost of rewiring, and reducing the seismic performance of the building, also requires year-round maintenance of the lines, especially for lines exposed outdoors, more frequent inspections are required to prevent damage caused by abnormal events and human causes; wireless Remote meter reading refers to the use of wireless communication transmission from the management center to the user's heat meter without laying any lines, the construction is simple, and it is very suitable for long-distance communication, but there are communication blind spots, and the accuracy and success rate of meter reading are lower than wired. transmission mode, and the operating cost is relatively high
