Real-time monitoring system for power transmission and distribution network based on 4G network and encryption mode

Abstract

The invention provides a real-time monitoring system for a power transmission and distribution network based on a 4G network and an encryption mode. The real-time monitoring method comprises the stepsthat: a monitoring terminal hoop is installed at a telegraph pole of a power transmission cable, collects internal electrical parameters and external environment data of the power transmission cable,and transmits the collected internal electrical parameters and external environment data to an encryption module; the encryption module encrypts the internal electrical parameters and the external environment data and returns the encrypted data to the monitoring terminal; a 4G wireless communication module transmits the encrypted data to a power server; the power server transmits the received data to an encryption machine, the encryption machine decrypts the data, and the decrypted data is returned to the power server; and the power server obtains final internal electric parameters and external environment data of the power transmission cable so as to judge whether a fault hidden danger occurs on site or not and position, record, alarm and process a fault position. Therefore, unattended all-weather monitoring of the power transmission cable is achieved.

Description

technical field [0001] The invention relates to the technical field of safety monitoring of distribution network transmission cables, in particular to a real-time monitoring system of a power transmission and distribution network based on a 4G network and an encryption method. Background technique [0002] Insufficiency of the existing power data transmission scheme: At present, the wireless public network GPRS transmission mode is widely used in the electric power. Since the public network of the mobile operator is used, there is a great hidden danger in the security of information. Furthermore, the GPRS network bandwidth is very small, and the transmission rate is very slow. Secondly, the existing power data transmission schemes use the operator's wireless public network for data transmission. Because the wireless public network is relatively open, anyone can easily access it, and it is safe. Not very good. . [0003] In addition, when encountering extreme weather condit...

[0002] Insufficiency of the existing power data transmission scheme: At present, the wireless public network GPRS transmission method is widely used on the electric power. Since the public network of the mobile operator is used, there is a great hidden danger in the security of information.

[0004] Therefore, at present, the security of power data transmission is not high, the delay is long, and the bandwidth is narrow, which limits the expansion of many businesses on power, such as substations, video surveillance of transmission lines, etc.

In order to make up for the many shortcomings of the current scheme, the following technical difficulties need to be solved: the security and reliability of information in network transmission; the problem of poor real-time performance in wireless transmission; the problem of narrow bandwidth and low rate of wireless transmission; Real-time monitoring of power cables
