Description

Technical Field

[0001] The present invention relates to the technical field of data communication, and in particular to an efficient communication method and system for a concentrator. Background Art

[0002] Concentrator communication is a communication mode in which multiple devices or terminals communicate through a central concentrator. The concentrator acts as a data aggregation point and is responsible for collecting, processing and forwarding data from various terminals. It is usually associated with a metering meter and is used to transmit metering data in the metering meter.

[0003] However, in the traditional communication method, the meter will directly transmit the data to the concentrator through the wireless network or GPRS (General Packet Radio Service), and the concentrator will forward the data to the control center. However, this method usually has problems such as high power consumption, waste of spectrum resources, low transmission efficiency, and incomplete signal coverage. In addition, if there are a large number of metering meters, the concentrator will frequently communicate with the control center, causing it to be overloaded, thereby affecting the stability of the entire system.

[0004] Therefore, in order to overcome the above defects, the present invention provides an efficient communication method and system for a concentrator. Summary of the invention

Secondly, according to the communication protocol, the slave terminal in the communication domain of the sub-concentrator is controlled to communicate and receive the operation data of the corresponding metering meter, thereby ensuring that it can effectively communicate with various types of terminals and ensure the reliability of data communication. At the same time, the received operation data is processed by the master terminal, and the abbreviation is generated and then transmitted to the main station, thereby reducing the communication load of the concentrator. Finally, the active data query request sent by the main station is monitored in real time, and the full operation data of the metering meter is transmitted to the main station when detected, thereby reducing the frequency of communication between the concentrator and the main station and improving the stability of the entire system.
