IC card intelligent water meter embedded with safety management module

Abstract

The invention discloses an IC card intelligent water meter embedded with the safety management module. An information safety management module is embedded into an IC card intelligent water meter, so that identity authentication is carried out when data exchange is carried out between the IC card intelligent water meter and a water selling management system through the IC card information exchangemodule, and the legality of communication between the IC card intelligent water meter and the water selling management system is guaranteed; an IC card intelligent water meter terminal main controllercan communicate with the outside only through the information safety management module; through a built-in data verification program, transmitted data are real, accurate and complete; meanwhile, theIC card intelligent water meter embedded with the information safety management module is simple in structure, can be seamlessly connected into a water supply management system through the internal information safety management module, achieves scattered manufacturing and unified management of the IC card intelligent water meter, is wide in application range, and guarantees independence of a watersupply company on terminal water meter control. The water meter is not limited by external factors.

Description

technical field [0001] The invention relates to an IC card intelligent water meter, in particular to an IC card intelligent water meter embedded with a safety management module, and belongs to the technical field of intelligent water meter safety management. Background technique [0002] In recent years, with the continuous development of electronic technology and the widespread use of IC card smart water meters, various brands of IC card smart water meters have appeared on the market. In order to facilitate the use and management, the water company began to adopt IC card smart water meters, and built its own management system on this basis. Since the same water company may use multiple brands of IC card smart water meters, each manufacturer independently masters the management methods of IC card smart water meters. Different brands of IC card smart water meters use different management systems, operating equipment, transmission media, management passwords, The operation mo...

Problems solved by technology

Since the same water company may use multiple brands of IC card smart water meters, each manufacturer independently masters the management methods of IC card smart water meters. Different brands of IC card smart water meters use different management systems, operating equipment, transmission media, management passwords, The operation mode causes the respective water companies to have no technical control over the IC card smart water meter. The IC card smart water meter can be separated from the management system of the water company, the information can be modified arbitrarily, and the usage status is controlled, so that a specific user or multiple Users can use tap water without paying, and the water company has the risk of losing control of IC card smart water meters

[0003] The level of safety technology and data exchange technology of various IC card smart water meter manufacturers is uneven, the control management technology and management system developed by each are not the same, and the safety guarantee cannot meet the requirements, resulting in some products in the information management. There are risks in the security and reliability of information exchange, and the application of encryption and decryption technology is unreasonable, so that illegal users can use corresponding technical means to obtain data in the transmission medium for analysis, decipher encryption algorithms and data protocols, and write corresponding With the program used by IC card smart water meters, tap water is sold without the management system of the water company, and the water company has the risk of losing control of the IC card smart water meter and the management system at the same time
