Communication method and system based on tcp protocol

Abstract

The invention provides a communication method and system based on a TCP. The communication system comprises a link establishment unit used for establishing a TCP link in response to a request for registering a network command; a server monitoring port unit used for establishing and maintaining a server monitoring port of at least one meter; a communication link request unit used for initiating oneor more TCP communication link requests for establishing TCP communication with external equipment when the server monitoring port receives a TCP communication link request or a data transmission request of the meter initiated by the external equipment; and a data transceiving unit used for opening the TCP link and actively disconnecting the TCP link after receiving or sending data. According tothe communication system based on the TCP provided by the invention, the problem that a large number of meter products maintain communication with a master station at the same time and occupy a largeamount of base station resources is avoided; the cost is saved for users; and remote meter reading of external equipment such as the master station, a PC host computer, an HHU and the like is realized, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of electric meter communication, in particular to a communication method system based on the TCP protocol. Background technique [0002] With the increasing application of smart meters around the world, a large number of smart meters rely on the mobile public network to form a remote communication network, so as to realize remote meter reading and remote control. At present, in the remote meter reading communication mode of the smart meter, although the communication module in the meter has SMS, CSD, USSD and other communication methods, the actual usage rate of these communication methods is low due to the small amount of communication data, low efficiency, and high cost. Low, most communication modules are based on GPRS / 3G / 4G mobile data network communication. [0003] In addition, with the more refined and diversified market demand for the master station business, some markets have proposed multiple mast...

Problems solved by technology

At present, in the remote meter reading communication mode of the smart meter, although the communication module in the meter has SMS, CSD, USSD and other communication methods, the actual usage rate of these communication methods is low due to the small amount of communication data, low efficiency, and high cost. Low, most communication modules are based on GPRS / 3G / 4G mobile data network communication

[0003] In addition, with the more refined and diversified market demand for the master station business, some markets have proposed multiple master station units for remote meter reading, and the master station, PC upper computer software, and HHU handheld devices for remote meter reading at the same time. In the scheme, the communication module is used as the client mode or the server mode respectively, and it will be difficult to simply meet the market demand
