Problems solved by technology

[0003] Strong loading capacity of the MBUS bus. When the MBUS bus of Type III and Type IV collectors is working, the load may have more than 100 water meters. Some water meters do not meet the specifications, absorb too much current, and the bus load is too large, causing on-site MBUS bus communication failure.
The MBUS bus receiving circuit adopts larger resistance sampling, resulting in high resistance loss, serious heat generation, waste of electric energy and changes of its own parameters, resulting in communication failure

Abstract

The invention discloses a type-III and type-IV collector with high MBUS load capacity. The collector comprises a 36V power supply, a single-chip microcomputer control circuit, an MBUS sending circuitand an MBUS receiving circuit. The type-III and type-IV collector has high MBUS load capacity and can adapt to site application requirements.

Description

technical field [0001] The invention relates to the field of smart grids, in particular to a Type III and Type IV collector with strong loading capacity of the MBUS bus. Background technique [0002] In June 2015, the State Grid Corporation put forward the requirement of "actively promoting the 'multi-meter integration' collection of electricity, water, gas, and heat", planning the integrated collection of water, electricity, and gas "three meters", and innovating the copying business model. Realize major reforms in the charging methods of water, electricity, gas and other public utilities. Realize full coverage and full collection of meter data collection in the station area On the basis of using the wireless collection network of electric meters to realize full coverage and full collection of water meters and gas meters. It can realize two-way real-time collection of water meter and gas meter data, laying the foundation for tiered water and gas prices, prepayment, etc. T...
