Mains power supplying type M-BUS multichannel intelligent data collection and teletransmission equipment

Abstract

The invention relates to mains power supplying M-BUS multichannel intelligent data collection and teletransmission equipment. The teletransmission equipment comprises a 32-bit microprocessor, an M-BUS module, an RS485 module, a GPRS module, an electric energy meter and a mains power supply module, wherein the M-BUS module, the RS485 module, the GPRS module and the electric energy meter are connected with the 32-bit microprocessor, and the mains power supply module is connected with a municipal administration power grid and is used for supplying power to the teletransmission equipment. Based on the integration of State Grid protocols 376.1 and 188, the interchange between the protocols is realized, and the required State Grid protocols are converted into a hardware-supported M-BUS protocol 188, and all functions of reading electronic meters, heat meters, gas meters and the like are realized; and meanwhile, by utilizing a mains power supplying manner, the power supply mode is simple and flexible.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and relates to a remote transmission device for data collection, in particular to an M-BUS multi-channel intelligent data collection remote transmission device powered by commercial power. Background technique [0002] At present, the power data acquisition remote transmission equipment on the market converts GPRS into TTL or 485 communication. The disadvantages of TTL and 485 are: TTL cannot realize long-distance communication and requires a power cord; 485 requires a power cord and requires 4 wires for communication, which greatly increases the cost, high cost of use and high failure rate. However, M-BUS communication only needs two wires, which greatly reduces the cost, the use cost and the failure rate are low, and each channel can be connected with multiple slaves in parallel, which is convenient and practical. [0003] However, the reading devices using M-BUS on the market...

Problems solved by technology

The disadvantages of TTL and 485 are: TTL cannot realize long-distance communication and requires a power cord; 485 requires a power cord and requires 4 wires for communication, which greatly increases the cost, high cost of use and high failure rate

In this way, the wiring and construction are complicated and the performance of the M-BUS host is different, which is easy to cause decoding errors

At the same time, the reading device uses transparent transmission, which has a long delay and a large flow
