When the loss-of-contact electricity meter 120 fails, the user energy consumption data acquired by the data acquisition module 122 cannot be transmitted through the data transmission module 121. Therefore, the data collection module 122 sends the user energy data to the data encryption module 123 for encryption, and then sends the user energy data to the data receiving module 115 of the proxy electric meter 110 through the execution module 124. The proxy meter 110 decrypts the received user energy data through the data decryption module 116, and finally transmits to the server through the data transmission module 117.

S611: and the proxy electric meter sends the second acquisition data to the server.
S612: the server receives second collected data from the proxy electric meter.
In a specific example, each smart meter performs data interaction with the server through the concentrator. The concentrator may include an uplink communication module, a downlink communication module, a power supply module, two ethernet interfaces, and a main control module.

The concentrator can configure information of each intelligent electric meter, establish connection with the terminal, and increase, modify or delete the intelligent electric meters communicated with the concentrator in batches. Optionally, the concentrator further includes a GPRS (general packet radio service) module, where the GPRS module is configured to implement GPRS wireless communication with the server, and the GPRS module is configured to convert a data packet into a GPRS wireless signal and send the GPRS wireless signal to the server, and receive GPRS data sent by the server and convert the GPRS data into a data packet and transmit the data packet to the main control module.
The concentrator may interact with the server via a wireless or limited network. The server can store and display the received data for the query and use of workers.
In a specific example, the server may query the configuration of the electric meters in the concentrator, analyze the conditions of the smart electric meters and the concentrator according to the pre-stored data and the electric meter data in the concentrator, determine whether each smart electric meter is successfully set according to the electric meter data, and determine whether the function of the concentrator for reading the electric meters is normal.
In some embodiments, the selection of the first proxy meter may be performed by the concentrator in step S102.
In a specific example, the data encryption module in the smart meter is used for converting the acquired data into encrypted data through a data encryption algorithm, combining the encrypted data with an identification code for identifying the smart meter to calculate and generate verification data, and finally sending the encrypted data and the verification data through the execution module.
Optionally, the data Encryption algorithm is a 3DES (data Encryption Standard, symmetric Encryption) algorithm, the verification algorithm for generating the verification data includes, but is not limited to, an MD5(Message Digest) algorithm, and the identifiers include, but are not limited to, an IMEI (International mobile Equipment Identity) code and an IMSI (International mobile Equipment Identity) code.
The 3DES encryption algorithm has high security in the face of strong attack, and the difference between the data size processed by the 3DES encryption algorithm and the data size before encryption is small. The 3DES algorithm can not only ensure the confidentiality problem of M2M (Machine to Machine) wireless data transmission, but also avoid the problem of redundant data or data multiplication in data transmission.
The MD5 check algorithm can convert a byte string of arbitrary length into 128 BITs and an integer of 16 bytes, and as a result, it takes only 16 bytes of redundant data. The algorithm is an irreversible character string transformation algorithm, has higher safety in the data transmission and verification process, and can effectively prevent the verified data from being modified in the M2M wireless data transmission process.
The intelligent electric meter want-to-pass method provided by this embodiment adds the IMEI code and the IMSI code to the MD5 data check, so that the MD5 algorithm can implement the terminal identity authentication function for the transmitting device.
The transmission process of the encrypted data comprises the following steps:
the method comprises the following steps: and a data acquisition module of the loss connection ammeter with the fault data transmission link acquires the original data of the user energy consumption.
Step two: the data encryption module of the loss of contact ammeter encrypts the original data to obtain first encrypted data.
The encryption process can be described as: DATA1 is 3DES (DATA0), where DATA1 is the first encrypted DATA, DATA0 is the original DATA, and 3DES is the symmetric encryption algorithm.
Step three: the data encryption module combines the identification code and the encrypted data of the unconnected ammeter into first data to be verified.
The generation process of the first data to be verified can be described as follows: DATA2 is DATA1+ IMEI + IMSI, where DATA2 is the first DATA to be verified, DATA1 is the first encrypted DATA, and IMEI and IMSI are identification codes.
Step four: and verifying the first to-be-verified data to obtain first verified data.
The process of checking may be described as MD5_ DATA1 ═ MD5(DATA2), where MD5 is the message digest checking algorithm and MD5_ DATA1 is the first check DATA.
Step five: and merging the encrypted data and the first check data into data to be sent, and sending the data to be sent to an execution module.
The process of merging the encrypted DATA and the first check DATA may be described as DATA3 ═ DATA1+ MD5_ DATA1, where DATA3 is the DATA to be transmitted.
Step six: and the data execution module of the loss-of-connection electric meter converts the data to be executed into an infrared signal and sends the infrared signal to the proxy electric meter.
Step seven: and the receiving module in the proxy electric meter receives the infrared signal, converts the infrared signal into an electric signal and then sends the electric signal to the decryption module of the proxy electric meter.
The electrical signal obtained by the infrared signal conversion is recorded as the received DATA4, the received DATA corresponds to the DATA3 to be transmitted in the step five, and the two are subjected to the photoelectric conversion only twice, and the DATA content is the same.
Step eight: the data decryption module splits the received data into second encrypted data and second check data.
The second encrypted DATA5 corresponds to the first encrypted DATA1, and the second parity DATA MD5_ DATA2 corresponds to the first parity DATA MD5_ DATA 1.
Since the MD5 parity algorithm is a large integer that changes a byte string of an arbitrary length to 16 bytes, the last 16 bytes of DATA of the received DATA4 are taken as the second parity DATA MD5_ DATA2, and the rest of the DATA4 to be received is taken as the second encrypted DATA 5.
Step nine: and acquiring an identification code corresponding to the lost connection electric meter prestored in the proxy electric meter, and combining the prestored identification code and the second encrypted data into third data to be verified.
The process of generating the third data to be verified may be described as: DATA6 is DATA5+ IMEI + IMSI, where DATA6 is the third DATA to be checked.
Step ten: and verifying the third data to be verified to obtain third verification data.
The verification process can be described as: MD5_ DATA3 is MD5(DATA6), where MD5_ DATA3 is the third check DATA.
Step eleven: and checking whether the second check data and the third check data are consistent, if so, decrypting the second encrypted data, and sending the decrypted data to the server through the data sending module via the concentrator.
Step twelve: and if the second check data is inconsistent with the third check data, abandoning the current data and continuously receiving new data.
If the verification is inconsistent, the verification of the data received by the proxy electric meter fails, the identity authentication cannot pass, and new data needs to be received for analysis and processing again.
In some embodiments, the server may upgrade the smart meter through the concentrator. For example, the server sends a request data packet to the smart meter through the concentrator, wherein the request data packet comprises upgrading request information and first upgrading port information. The upgrade request information in the request packet includes software version information and query request information stored in the server. And after receiving the request data packet, the intelligent electric meter generates a confirmation data packet according to the request data and sends the confirmation data packet to the server through the concentrator. The confirmation data packet includes upgrade feedback information and second upgrade port information and a flag bit. The zone bit is used for recording the CPU utilization rate of the intelligent electric meter during the current software operation. And the server judges whether each intelligent electric meter needs to be upgraded or not by confirming the data packet, if so, the server continues to execute the upgrading program, and if not, the server terminates the upgrading program. A network upgrading channel is established between the server and the intelligent electric meter and used for communicating the first upgrading port with the second upgrading port, the server sends upgrading files to the intelligent electric meter through data upgrading, and the intelligent electric meter upgrades according to the upgrading files. And after the upgrade is finished, the intelligent electric meter feeds back mark information to the server, wherein the mark information comprises the latest software version information of the model of the intelligent electric meter.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
