State embodiment and be only the preferred embodiments of the present invention, and not all.Based on the embodiment in embodiment, those skilled in the art
On the premise of not making creative work, obtained other embodiment, broadly falls into protection scope of the present invention.
Embodiment 1.
Referring to Fig. 1, based on the read-write card means of communication of electric energy meter and terminal, comprise the steps:
Step 101: terminal sends authentication instruction to electric energy meter；Electric energy meter receives authentication instruction and recognizes identity
Card instruction is compared with the first ciphertext；
Step 102: when comparing successfully, then send correct response to terminal, when comparing unsuccessfully, then send abnormal answering to terminal
Answer；
Step 103: terminal receives correct response, terminal sends wallet file and parameter information file to electric energy meter；Electric energy
Table receives wallet file and parameter information file, and judges whether that needs are supplemented with money according to wallet file；
Step 104: if desired supplement with money, electric energy meter writes wallet file to storage table.
Step 106: after the completion of write, electric energy meter returns successful recharging information to terminal.
In abovementioned steps 103, wallet file includes the power purchase amount of money in card interior power purchase number of times and card,
When in the table of electric energy meter, power purchase number of times is equal to power purchase number of times in card, electric energy meter sends to terminal and does not supplement response with money；
When in card, power purchase number of times is power purchase number of times+1 in table, then electric energy meter writes wallet file to storage table；
When in card, power purchase number of times is other situation, then electric energy meter sends exception response to terminal, and other situations are non-table
Interior power purchase number of times is power purchase number of times+1 in table equal to power purchase number of times in power purchase number of times in card and card.
Between abovementioned steps 104 and step 106, carry out step 105, judge whether to need undated parameter information, work as protheca
Electricity price file and standby set electricity price file；
Parameter information file includes parameter and updates flag bit and parameter information；Parameter updates flag bit and includes parameter information mark
Will position, when protheca flag bit and standby set flag bit.
Electric energy meter receives parameter information file, and judges wherein to whether there is to update to indicate, if there is not renewal flag bit,
Then electric energy meter sends response ending message to terminal；
When only existing parameter information flag bit, then electric energy meter is to storage table write parameters information；When there is parameter information mark
Will position and work as protheca flag bit, then electric energy meter receives parameter information and when protheca electricity price file write storage table, and terminal sends
When protheca electricity price file is to electric energy meter；When existing parameter information flag bit and standby set flag bit, then electric energy meter reception parameter
Information and standby set electricity price file simultaneously write storage table, and terminal sends standby set electricity price file to electric energy meter；Believe when there is parameter
Breath flag bit, when protheca flag bit and standby set flag bit, electric energy meter receives parameter information, when protheca electricity price file and standby set
Electricity price file simultaneously writes storage table.
