Accompanying drawing explanation
Fig. 1 is USB infrared communication module map of the present invention.
Detailed description of the invention
Below by way of detailed description of the invention, the invention will be further described.
The remote infrared Verification System of a kind of electric energy meter of the present invention, including electric energy meter and mobile terminal, also includes
Private server, for receiving the infrared certification request instruction uploaded, and is sent to state's net encryption equipment by this instruction
And forward the infrared certification of return to instruct.This private server and state's net encryption equipment realize data communication by LAN, pass through
LAN also asks for the data needed for infrared certification according to state's net encryption equipment communications protocol to state's net encryption equipment, including random number,
Dispersion factor, ciphertext etc..
This mobile terminal, with private server by internet carry out data communication with send infrared certification request instruction and
Receive and return infrared certification instruction；And be connected to transmit infrared certification instruction to it with USB interface.
USB infrared communication module, with reference to Fig. 1, this USB infrared communication module includes USB interface, infrared transmitter, infrared
The infrared carrier signal of receptor, UART chip and 38KHz produces circuit.The infrared carrier signal of this 38KHz produces circuit with infrared
Transmitter is connected to provide the infrared carrier signal of 38KHz needed for infrared signal；This UART chip is connected with USB interface with by red
Outer certification instruction carries out the conversion between usb data and UART data；Infrared transmitter is connected with UART chip with by this conversion
After infrared certification instruction send to electric energy meter；This infrared remote receiver receives the result that electric energy meter returns.This USB is infrared logical
News module is powered by mobile terminal by USB interface.
Electric energy meter, is provided with infrared receiving/transmission circuit, ESAM safety certification chip etc., and this electric energy meter receives infrared certification and instructs also
Extract random number and the first ciphertext, this random number is delivered to this ESAM safety certification chip by ISO7816 agreement and adds
Close obtaining the second ciphertext, by comparing, the first ciphertext is the most identical with the second ciphertext determines certification whether success, and sends checking
Result.
Further, the private server of the present invention is additionally provided with the task of checking meter for downloading task of checking meter for mobile terminal
Unit and for storing the meter reading data storage element of meter reading data copied back from mobile terminal.
The UART chip model of the present invention is FT311D, mobile terminal be mobile phone or panel computer or notebook computer or
PDA.The specific works process of present system is as follows:
First, mobile terminal sends infrared certification request instruction to private server, and this instruction is sent by private server
To state's net encryption equipment, state's net encryption equipment feeds back infrared certification and instructs to private server.Infrared certification is instructed by private server
Send to mobile terminal.Mobile terminal receives the infrared certification of return and instructs and send it to USB infrared communication by USB interface
Module；
Then, the UART chip of USB infrared communication module is by instruction morphing for the infrared certification of usb data form one-tenth UART number
According to.Infrared certification after this conversion is instructed and combines the transmission of 38KHz infrared carrier signal to electric energy meter by infrared transmitter.This electric energy
Table judge after receiving infrared certification instruction the legitimacy of whole communication frames guarantee without disconnected frame, data without losing (by judge frame head,
Postamble, frame check code the most correctly realize), then take out the dispersion factor in frame, random number and the first ciphertext etc., pass through
This random number is delivered to this ESAM safety certification chip and is encrypted and obtains the second ciphertext, by comparing first by ISO7816 agreement
Ciphertext is the most identical with the second ciphertext, if identical, certification success, and send the result.
Finally, this infrared remote receiver receives the successful the result of certification that electric energy meter returns, and carries out turning through UART chip
After change, being sent the result to mobile terminal by USB interface, mobile terminal reads this result and parses electric energy meter
Correctly perform infrared certification instruction, thus complete whole infrared identifying procedure.Electric energy meter is infrared by opening after infrared certification
Copy reading authority, mobile terminal can download the task of checking meter, required in reading table by infrared transmitter and infrared remote receiver
Total data, and the meter reading data copied back is stored in mobile terminal, it is also possible to it is sent in real time private server.
Above are only the detailed description of the invention of the present invention, but the design concept of the present invention is not limited thereto, all utilize this
Design carries out the change of unsubstantiality to the present invention, all should belong to the behavior invading scope.
