Embodiment
The present invention is further elaborated below in conjunction with accompanying drawing.
With reference to shown in Figure 1, one embodiment of the present of invention are a kind of remote-control intelligent electric energy meter information security management modules, described information security management module comprises processor, first data-interface, second data-interface and FLASH storer, described processor inserts first data-interface, second data-interface and FLASH storer respectively, wherein:
The effect of above-mentioned first data-interface is to carry out the remote-control intelligent electric energy meter to communicate by letter with the unique data of data transmission module, and transmits it to processor when receiving the external data that comes from data transmission module; Described data transmission module directly receives the external data that comes from long-range management system for selling power;
The effect of above-mentioned FLASH storer is control and the documentor in the canned data safety management module;
With reference to shown in Figure 1, the effect of above-mentioned second data-interface is the data communication of carrying out between processor and the remote-control intelligent electric energy meter terminal master controller, and the effect of remote-control intelligent electric energy meter terminal master controller is to carry out the operation of respective table end according to the instruction of processor;
The effect of above-mentioned processor is when receiving the external data that comes from first data-interface, the management system for selling power that sends external data is carried out authentication, judge whether to obtain encrypted packets in this external data, and send corresponding operational order by second data-interface to remote-control intelligent electric energy meter terminal master controller according to the affairs that comprise in the data.
According to above-mentioned technical scheme as can be known, the technical matters that present embodiment solved is the information security management module by above-mentioned composition structure, between remote-control intelligent electric energy meter terminal master controller and management system for selling power, carry out data forwarding, and when transmitting, authenticated and encryption and decryption, thereby cooperate Utilities Electric Co. that the intelligent electric energy meter of terminal is managed, to eliminate the risk of information security management in Utilities Electric Co.'s operation.
And the Oscillator module shown in Fig. 1 and pin XIN, XOUT provide clock signal to the information security management module; The RAM storer is used for the operating ephemeral data of memory module; VCC and VSS two pins provide working power for the information security management module, and this power supply should be a continued power and can not being provided by the pin of remote-control intelligent electric energy meter terminal master controller.
