Abstract

The invention discloses an IC card intelligent water meter provided with an information security management module in an embedded mode. The IC card intelligent water meter comprises the information security management module which comprises a processor, a first data interface, a second data interface and an FLASH memorizer, wherein the processor respectively accesses the first data interface, the second data interface and the FLASH memorizer, identity authentication is conducted when data exchange is conducted between the information security management module and a water sale management system through an IC card reading module, validity of communication between the information security management module and the water sale management system is guaranteed, and an IC card intelligent water meter terminal master controller can conduct communication with the outside only through the information security management module. Different secret keys are used for achieving permission setting of level-to-level administration of a water supply company, triple data encryption algorithm (3DES) / advanced encryption standard (AES) multilevel encryption modes are adopted, the secret keys can be upgraded in real time through a program download interface on the information security management module, and risks caused by exposure of the secret keys are avoided. Meanwhile, the IC card intelligent water meter can guarantee terminal meter control independence of the water supply company, and is free of restriction of the outside.

Description

technical field [0001] The invention relates to an intelligent water meter, more specifically, the invention mainly relates to an IC card intelligent water meter embedded with an information security management module. 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 mode causes the respective water companies...
