Abstract

The invention discloses a remote safe meter reading system, comprising a background management center, a collection module and front-end equipment. A remote safe meter reading method comprises the following processes: 1) sending a meter reading command by the collection module; 2) reporting the command to the background management center; 3) validating the identity of a gatherer; 4) extracting an identity (ID) of the collected front-end equipment; 5) generating a new session key; 6) encrypting the extracted ID information and metering reading command; 7) transmitting information to the front-end equipment, and transmitting the session key to the collection module and the front-end equipment; 8) decrypting and confirming information by the front-end equipment; 9) reading data by the remote meter reading module; 10), packaging and encrypting the ID information, collected data and MAC check code and then transmitting to the collection module; 11) receiving the ID information and data; 12) uploading the data to a safety server; and 13) storing and updating information by the safety server. The functions of identity authentication and data encryption are achieved in the remote meter reading process, and the security level is greatly improved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a remote safe meter reading method. Background technique [0002] At present, the remote meter reading system is mainly composed of front-end equipment, collection equipment and background management center. Among them, the front-end equipment includes electric meters, water meters and gas meters, and the collection equipment is concentrator or meter reading machine. [0003] The front-end equipment is equipped with a sensor device, which is called a remote meter reading module in this paper, and has a unique ID. The remote meter reading module usually uses photoelectric direct reading technology to directly read the number of the meter code disc. According to the data communication mode between the remote meter reading module and the concentrator or meter reading machine, the remote meter reading module can be divided into two types: wired remote meter reading mo...
