Abstract

The invention provides an HBUS bus meter reading system, wherein a power supply box, a data concentrator, a data transmitter and various terminal devices are respectively connected to one ends of eachcorresponding terminal box through two-core cables, and the other ends of each terminal box are connected to a HBUS bus through two-core cables. According to the present invention, the cost of the cable is reduced compared to the four-wire connection mode in the prior art; the HBUS bus does not have the topology structure limitation, and can be arbitrarily expanded in cascade, such that the problem of the limited load number in the prior art is solved; and the HBUS bus has the long transmission distance, such that the data transmitter can be arranged at any positions of the building structureso as to optimize the communication between the remote network and the data concentrator and improve the reliability of data reading so as to improve the data reading rate.

Description

technical field [0001] The invention relates to the technical field of meter reading systems, in particular to an HBUS bus meter reading system. Background technique [0002] The meter reading system is mainly to upload data from terminals such as electric meters, water meters, gas meters, and heat meters to the server. At present, data collection and reading of terminals are mainly carried out through wireless or wired methods. Among them, the wireless meter reading system realizes point-to-point data set reading by networking the terminals, but its data transmission is easily affected by signal interference and the layout of the on-site house structure, resulting in the failure of data copying and affecting the reliability of copying, thereby reducing copying. Rate. [0003] The wired meter reading system mainly uses the RS-485 or M-bus reading system to realize data reading, which improves the reading rate compared with the wireless meter reading system; however, the RS-...
