The invention discloses an intelligent
gas meter with an information safety management function, belonging to an intelligent
gas meter. The intelligent
gas meter comprises an intelligent gas meter terminal main controller and a
FLASH memory, wherein the intelligent gas meter terminal main controller is accessed to a communication object through an
external data interface; the
external data interface is used for executing sole data communication between the intelligent gas meter terminal main controller and the communication object; when being received,
external data from the communication object are transmitted to the intelligent gas meter terminal main controller through the external
data interface; through the adding of the information safety management function in the intelligent gas meter terminal main controller, when exchanging data with a gas sale
management system of a gas company through the communication object, the intelligent gas meter terminal main controller performs identity
authentication; therefore, the legality of communication between the intelligent gas meter terminal main controller and the communication object is guaranteed; moreover, the intelligent gas meter terminal main controller is accessed to a
gas management system in a seamless way through the external
data interface, so that the dispersed manufacturing and the uniform management of the intelligent gas meter are realized; and meanwhile, the control independence of the gas company on the gas meter is guaranteed, and the restriction by the outside is avoided.
