Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings, embodiment is elaborated.
Based on the deficiencies in the prior art, technical problem to be solved in the utility model is to introduce effective appearance
Wrong mechanism realizes the integrated encryption of electricity consumption data.As it is shown in figure 1, it is proposed that one is applied to electrical network in fact
Time scheduling and with the electricity consumption data encryption system of fault tolerant mechanism, including: intelligent electric meter, ciphertext integrator,
Key distrbutor, grid dispatching center, intelligent electric meter is arranged on user side, by the radio of 230MHz
Power private network is connected with ciphertext integrator；Key distrbutor by twisted-pair feeder or optical fiber and each intelligent electric meter and
Ciphertext integrator communicates；Ciphertext integrator, receives, by wireless power private network, the letter that all intelligent electric meters are sent
Breath, and use twisted-pair feeder or optical fiber and grid dispatching center, key distrbutor communication.
First, at intelligent electric meter, introduce retransmission mechanism.By judging that whether receptor is in the time of setting
Inside receiving the response signal of ciphertext integrator, infer whether message sends successfully, if sending unsuccessfully, then weighing
New transmission；
Then, at ciphertext integrator, fault tolerant mechanism is introduced.By judging that receptor is whether when setting
In receive the information of intelligent electric meter, infer whether intelligent electric meter damages.If damaging, then choose and this use
The intelligent electric meter information of other users that family electricity consumption type is close replaces, and carries out integrated deciphering；
Finally, at key distrbutor, set up two kinds of key updating mechanism.One is to be entered by timer
Line period formula updates, and just carries out periodic renewal when timer has reached the time set in advance；Another
It is to carry out trigger-type renewal by trigger, when the intelligent electric meter having new intelligent electric meter to add or to damage is too much
Time, trigger action, cause key updating.
A Node registry storehouse set up by the way of user registers by key distrbutor, subsequently according to each use
The log-on message at family generates encryption key and the decruption key of ciphertext integrator of user respectively.
Key distrbutor is provided simultaneously with two kinds of key updating modes, is that trigger-type updates and periodic updates respectively.
When the quantity that ciphertext integrator is delivered in trigger to damage intelligent electric meter exceedes prescribed limits or have new joint
Point add fashionable, trigger will action, key distrbutor will call Node registry storehouse and carry out key updating；
When timer reaches time threshold set in advance, key distrbutor the most also can be caused to carry out key updating.
I.e. two conditions have one to meet, and will carry out key updating.
After intelligent electric meter carries out data acquisition, it is encrypted gathering the data come by data encryption module,
Emitted device is sent to ciphertext integrator, the backup of encryption data is stored in caching storehouse simultaneously.Emitter
Once having sent encryption data, signal controller just starts timing.When receptor receives ciphertext integrator
During response signal, if response signal is " sending successfully ", then timer stops timing, does not carry out any
Operation；Whereas if response signal is " sending unsuccessfully ", or reach time threshold set in advance still
Do not receive response signal, just think that message sends unsuccessfully.Now, signal controller can call caching immediately
Backup Data in storehouse, is resend by emitter and adds confidential information.
The signal controller of ciphertext integrator has clocking capability equally, because different intelligent electric meter information passes
The time reaching ciphertext integrator is different, so being provided with n timer in signal controller, is respectively
Each intelligent electric meter timing.Receptor often receives the encryption data of an intelligent electric meter, will be encryption
Data are put in ciphertext storehouse.Now, in signal controller, the timer corresponding to this intelligent electric meter will reset,
And sending response signal by responsor to this intelligent electric meter, content is " sending successfully "；Work as signal controller
In the timer corresponding with certain intelligent electric meter reach time threshold and the most do not receive this Intelligent electric subtabulation number
According to time, just think that intelligent electric meter message sends unsuccessfully, now, signal controller pass through this intelligence of responsor feedback
Can respond signal by ammeter, content is " sending unsuccessfully ".Ciphertext integrator continues waiting for this intelligent electric meter subsequently
Retransmission of information, if the most not receiving encryption data when again reaching the time threshold of timer, just thinks this
Intelligent electric meter has damaged.Now, signal controller will be chosen and this intelligent electric meter from ciphertext storehouse
The intelligent electric meter of same type ' data replace.Finally, ciphertext integrator calculates institute by deciphering module
Have the power consumption summation of user, employing twisted-pair feeder or optical fiber passes to grid dispatching center in form.Meanwhile,
The information of the intelligent electric meter of damage is passed to the trigger in key distrbutor by signal controller.
All user power utilization amount summations that grid dispatching center is uploaded according to ciphertext integrator, are collected by curve
Module carries out load curve drafting, formulates scheduling strategy and generation schedule.Because control centre is according to electrical network
The general trend of load formulates scheduling strategy, so several intelligent electric meters produce fault by other electricity consumption classes
The similar intelligent electric meter information of type replace caused by error be negligible.When electricity in some time period
When net overall load is on the low side, just can reduce electricity price, encourage user's Multifunctional electric；When network load is higher, just
Electricity price can be improved, advocate user and reduce electricity consumption, and promote generated energy, thus ensure electrical network on the whole
Steady load, saves the cost of balanced load.
Additionally, the information transmission between intelligent electric meter and ciphertext integrator uses 230MHZ wireless power
Private network, has used frequency spectrum perception, carrier aggregation technology, and stability and the real-time of communication are greatly improved.
This embodiment is only this utility model preferably detailed description of the invention, but protection domain of the present utility model
It is not limited thereto, the technical scope that any those familiar with the art discloses at this utility model
In, the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Therefore,
