Dual-input multi-meter composite acquisition system and method

Abstract

The invention discloses a dual-input multi-meter composite acquisition system and method, and mainly aims to solve the problem that water, gas and heat meters of M-BUS communication cannot be directlyread by the traditional acquisition unit of an existing power acquisition system. The dual-input multi-meter composite acquisition system comprises a dual-input multi-meter composite acquisition device, a computer and a pressure generating device, wherein the double-input multi-meter composite acquisition device comprises a communication interface converter, a protocol conversion module, a carrier module, a carrier concentrator, a data processing module, a breakage report module, a communication module, an M-BUS receiving circuit module, an M-BUS output circuit module and a voltage conversioncircuit module; the pressure generating device comprises a pressure generating module, a charger, a digital inverter and a storage battery. The dual-input multi-meter composite acquisition system andmethod disclosed by the invention are suitable for acquiring all kinds of meter data. During field installation, only one piece of composite acquisition equipment needs to be installed on site, so that the acquisition unit and the protocol converter do not need to be installed in a traditional way, and the cost of field equipment and the installation space are saved; meanwhile, the pressure generating device is used for supplying power, so that the energy saving and environmental protection effects are enhanced.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a dual-input multi-meter composite acquisition system and method. Background technique [0002] With the development of science and technology, the current power acquisition system technology has become more and more mature, but the existing technology can only read the electric meter directly. If you want to collect water, electricity, gas and heat multi-meter data, you need to install it on the basis of the power system acquisition system. The protocol converter and the collector are combined to realize the multi-meter-in-one collection function. The water, gas and heat meters using M-BUS communication need to be converted into DL / T645-2007 general protocol data through the protocol converter, and then the data will be transmitted. To upload to the master station on the carrier concentrator that collects the carrier energy meter, a protocol converter needs to be installed on s...
