Power carrier MBUS (meter bus) data converter and remote control method of MBUS equipment

Abstract

The invention discloses a power carrier MBUS data converter and a remote control method of MBUS equipment. The power carrier MBUS data converter comprises a power carrier communication module, a power supply module, a boost circuit, an MCU (microprogrammed control unit), an MBUS transmission circuit and an MBUS receiving circuit. The output end of the power supply module is connected to the power carrier communication module, the boost circuit and the MCU, the output end of the boost circuit is connected to the MBUS transmission circuit, the power carrier communication module is connected to the MCU, and the MCU is connected with the MBUS transmission circuit and the MBUS receiving circuit respectively. By means of the effective combination of the power carrier technology and the MBUS technology, the power carrier MBUS data converter can complete the bi-directional conversion of MBUS data and power line carrier communication data, achieves the remote control on MBUS terminal equipment such as meters and has the advantages of long communication control distance, no MBUS data line redistribution and arrangement, simple construction and the like.

Description

technical field [0001] The present invention relates to the application field of power carrier communication technology, in particular to the technology of controlling remote MBUS equipment based on power carrier communication technology, and in particular to a power carrier MBUS data converter and a remote control method for MBUS equipment. Background technique [0002] MBUS (meter bus) is a new type of bus structure. Its main feature is to simultaneously supply power and transmit serial data through two non-polar transmission lines, and each substation (confirmed with a different ID) is connected in parallel on the MBUS bus. When MBUS is used in the energy consumption intelligent management system of various instruments or related devices, relevant data or signals can be collected and transmitted to the concentrator, and then transmitted to the master station through the corresponding interface. The use of MBUS can greatly simplify the wiring and connection of energy consu...

Problems solved by technology

However, the existing MBUS bus directly adopts dedicated line technology, and wiring must be completed from each terminal to the control terminal. The construction is time-consuming and laborious, especially in existing buildings. The construction work is huge and the efficiency is extremely low.

What's more important is that when controlling various instruments and terminal equipment connected to the MBUS bus, it can only be realized through the RS485 communication module based on the MBUS bus that has been deployed in the building, and it cannot be remotely controlled. Control. In the prior art, when these instruments and other terminal equipment are to be remotely controlled, the remote MBUS bus must be specially re-arranged, resulting in a substantial increase in actual control costs and limiting its actual use value.

Power carrier is a unique communication method for power systems. Power carrier communication refers to the technology of using existing power lines to transmit analog or digital signals at high speed through existing power lines. The biggest feature is that there is no need to re-establish the network. It is one of the ideal ways for short-distance communication, but the current power carrier technology has not been widely used due to problems such as clutter and crosstalk, and it has not been used in combination with MBUS bus technology.
