Specifically, the purpose of communication between the terminal and the server is to obtain a field operation and maintenance work order, the terminal device writes operation and maintenance information into an RFID electronic tag on the electric energy meter through a terminal RFID module, and uploads related operation and maintenance work orders to the server at the same time, wherein the operation and maintenance information comprises operation and maintenance records, the operation and maintenance records comprise operation and maintenance records of the electric energy meter such as compensation reading, time synchronization, module replacement, metering abnormity and the like, a real-time uploading mode or an offline buffering mode can be adopted for uploading the operation and maintenance information to the server so as to meet the application requirements of a network blind area, and the operation and maintenance information is transmitted after being encrypted in the transmission process.
Specifically, the encryption algorithm used in this embodiment is a DES encryption algorithm, and DES is symmetric, that is, the DES encryption algorithm uses the same key to encrypt and decrypt data. DES is also a packet encryption algorithm that processes fixed-length data segments, i.e., packets, at a time. The DES packet is 64 bits in size and if the encrypted data length is not a multiple of 64 bits, the bits may be padded according to some specific rule. The security of DES relies essentially on the appearance of artifacts, and in cryptographic terms on the principle of "confusion and diffusion". The purpose of obfuscation is to hide any relationship between plaintext and ciphertext, or key, while the purpose of diffusion is to make the significant bits in plaintext and key together make up as much ciphertext as possible. The combination of the two makes the security relatively high. The DES algorithm encrypts the plaintext by performing a series of permutation and substitution operations. The key to the process is a function that derives 16 sub-keys from a given initial key. To encrypt a set of plaintext, each subkey is applied to the data in a series of bit operations in the order, i.e., 1 to 16, once for each subkey, for a total of 16 repetitions. Each iteration is referred to as a round. The same steps can be used to decrypt the ciphertext except that the subkeys are processed in the reverse order, i.e., 16 to 1, for the ciphertext. And the DES algorithm is relatively simple to realize compared with other encryption algorithms, is mainly realized by adopting C language, is easy to obtain, and has relatively low labor cost and material cost.
Specifically, the operation and maintenance personnel can check the current operation and maintenance information of the electric energy meter through the terminal.
