Problems solved by technology

However, in some cases, there is no special power network or the construction of laying optical cables is very inconvenient.
At this time, you can consider using an existing mature commercial network, but the data is transmitted in plain text without encryption, and there is a risk of being monitored and tampered with
Although the use of software encryption is convenient and does not increase hardware costs, it is realized by occupying general-purpose CPU computing resources. The encryption and decryption efficiency is low, and there is a risk of being infected by a Trojan virus and leaking secrets.

Embodiment Construction

[0048]The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0049] Such as figure 1 As shown, it includes two parts: background system and front-end status monitoring equipment.

[0050] The background system includes a key generation module, a first public key distribution module, an encryption module, a decryption module, a first data transmission module, a data storage display module and a control processor, wherein the key generation module, the encryption module, and the decryption module of the background system Set in the first chip, after the control processor is started, the key generation module is initialized first, and N pairs of key pairs are obtained, and a pair of key pairs includes a public key and a private key. The public key is transmitted to the remote device, and the private key is kept by itself. The data encrypted with the public key can only be decrypted with the corre...

Abstract

The invention relates to a transformer remote monitoring system and a working method of the system, specifically to a transformer remote monitoring system with a special encryption / decryption chip and a working method of the system. At present, data of a transformer monitoring device is transmitted in a plaintext mode, the data may be monitored and tampered in the transmission process, and therefore, the operation security of a transformer is influenced seriously. The system comprises a background system and multiple front-end state monitoring devices. The background system comprises a first chip, a first data transmission module, a data storage and display module and a control processor. Each front-end state monitoring device comprises a second chip, a transformer state monitoring device and a second data transmission module. The first data transmission module and the second data transmission modules are connected by a public network. According to the technical scheme, hardware asymmetrical encryption is carried out on the transmitted data by a commercial network, and various states of the transformer can be monitored online safely and efficiently.

Description

technical field [0001] The invention relates to a transformer remote monitoring system and a working method thereof. Background technique [0002] At present, the data transmission of transformer monitoring equipment is in plain text, and the data is likely to be monitored and tampered with during transmission. Seriously affect the safety of transformer operation, so the current transformer monitoring equipment data is only transmitted in the power private network. In each substation, a communication room will be designed, and an optical cable will be laid to the upper-level substation, and the upper-level substation will be cascaded up to the provincial control center. In this way, through several levels of cascading, each substation can communicate with the provincial control center. Thus forming a large electric power network. If the transformer monitoring equipment wants to upload data through the power private network, it needs to lay an optical fiber to the communic...
