Multi-master and multi-slave transparent transmission system of BLE Bluetooth electric energy meter

Abstract

The invention relates to the field of electric energy meters, and discloses a multi-master multi-slave transparent transmission system of a BLE Bluetooth electric energy meter. The system comprises master-slave BLE Bluetooth pairing, standard protocol data inspection, working mode selection and communication system performance verification. According to the invention, the problem that layout and wiring need to be considered on site during construction of a traditional electric energy meter is solved, the BLE adopts an asymmetric encryption technology, data transmission has better safety, the BLE adopts radio communication, the problem that data transmission needs to be aligned does not exist, and when a large amount of data is collected, the correctness of data transmission can also be guaranteed, the transmission distance is relatively long, multiple paths of data can be verified at the same time, transparent transmission and sharing of the data can be realized, the state of each node can be mastered in real time, the equipment replacement is more flexible, and the electric energy meter can discover the abnormity of the terminal equipment in time and report the state of the intelligent terminal equipment in time; the equipment is convenient to replace in time, the safety of data communication is guaranteed, and the data communication of the equipment can be recovered in time.

Description

technical field [0001] The invention relates to the field of smart electric meters, in particular to a multi-master and multi-slave transparent transmission system for BLE bluetooth electric energy meters. Background technique [0002] BLE (Bluetooth Low Energy, Bluetooth low energy module) Bluetooth energy meter multi-master and multi-slave transparent transmission system is a multi-master, multi-slave, low power consumption, low delay, and data security obtained in the field of energy meter data monitoring Safeguarded remote monitoring means; [0003] The layout and wiring of the traditional electric energy meter needs to be considered in the on-site engineering construction. The insulation performance of each terminal cannot be guaranteed to be reliable. It is difficult to ensure that the terminal is firm and not loose for a long time after installation. In the case of poor insulation performance, there are great potential safety hazards for personnel safety, and data se...
