The present invention will be further described below in conjunction with the accompanying drawings and embodiments. the

Detailed ways

As shown in the figure, a distribution network information management system includes a central server, and the central server is connected to a distribution monitoring system, a distribution network automation system, a distribution line detection system, a line inspection system, and a remote control system through a 3G network. Video monitoring system, mobile office system and remote dynamic video management system, the central server conducts unified management and comprehensive energy efficiency analysis on the information returned by each system. the

The power distribution monitoring system includes a monitoring server, which is connected to a data acquisition terminal and a 3G communication unit that communicates wirelessly with the central server. The traditional GPRS power distribution management system, due to insufficient bandwidth, limited concurrent numbers, and unreliable security performance, etc., It is difficult to realize real-time data transmission in the true sense. The 3G network is used to realize the whole process and full range monitoring of power distribution management. The data collection terminal collects the voltage, current, load and other information of electricity customers and sends them to the central server at regular intervals. The staff can monitor each customer's electricity consumption status in real time and make dynamic analysis without leaving home. Management loopholes can avoid the phenomenon of favoritism and relationship, and improve the company's demand side and lean management level. the

The distribution network automation system includes a master station server. The master station server is connected with a communication control device and a 3G communication unit for wireless communication with the central server. The communication control device is connected with a telecontrol device. The distribution network automation communication method is mostly based on optical fiber EPON. However, in practical applications, due to high cost, long construction period and great construction difficulties, the development of distribution network automation is seriously restricted. 3G network has the advantages of wireless transmission, high bandwidth, and strong real-time performance, which fully meets the requirements of distribution network automation. Therefore, the use of this communication method can solve the above problems well. The 3G method adopted realizes real-time uploading of information, remote control, and automatic isolation of faults and rapid recovery of power transmission through the main station, which not only improves the reliability and quality of power supply, but also improves the economic benefits and management level of the enterprise;

The distribution line detection system includes a fault indicator, which is connected with a 3G communication unit and a satellite positioning device for wireless communication with the central server. Rapid and accurate fault location is of great significance for improving power supply reliability. The power grid has a large number of lines, many branches, complex operation mode, and frequent faults. Since the traditional fault indicator has no positioning function, fault finding is time-consuming and laborious, and the workload of maintaining the line is heavy. On the basis of the traditional fault indicator, 3G communication unit and satellite positioning function are added. In this way, not only the real-time information of the line can be detected, but also when the line is short-circuited or grounded, the fault indicator will issue an alarm and quickly lock the fault range, thereby shortening the time to find the fault, reducing the work intensity of personnel, and improving work efficiency ;

The line inspection system includes several inspection terminals. The inspection terminals are equipped with cameras. The inspection terminals are connected with 3G communication units that communicate wirelessly with the central server. Operation inspection of power transmission and distribution lines is the basic work of safety production management. Line inspection The work is generally done manually. If only relying on supervision and assessment, it is difficult to ensure that the inspectors can complete the inspection work on time, according to the amount and on schedule, and there are certain safety hazards. The present invention equips each inspector with an inspection terminal, which records information such as the inspection content and scope, and can monitor the location, arrival time and whether the inspector can earnestly perform work duties through the 3G network in real time, so that Effectively eliminate potential safety hazards caused by human factors such as inadequate inspections. When the inspectors find a line fault, they will take pictures of the fault site through the terminal camera and send it to the monitoring center in real time, and the relevant personnel can organize emergency repair materials according to the site situation and put in the emergency repair in time, thus greatly shortening the repair time limit and reducing power outages Time, improve the reliability of power supply;

The remote video monitoring system includes a monitoring camera, which is connected to a 3G communication unit that communicates wirelessly with the central server. The theft of distribution network transformers, especially agricultural irrigation transformers, is very serious, not only causing property losses, but also bringing great harm to grassroots services. How to improve the safety precautions of power distribution rooms has become an important issue that power supply enterprises need to solve urgently. A small number of units adopt the remote video monitoring method, but because video monitoring requires high network bandwidth, and GPRS is far from meeting the requirements of image transmission, there are certain defects in practical applications. The 3G network bandwidth is high, and the ability to transmit video in real time is strong. The power distribution room can be monitored 24 hours through remote video, which effectively eliminates management blind spots and avoids the occurrence of transformer theft. At the same time, 3G wireless video can also be used to monitor transmission lines, real-time monitoring of transmission line ice conditions, insulator pollution flashover and lightning strikes, which greatly improves the safety of transmission lines and the company's safety production management level;

The mobile office system includes mobile terminals that communicate with each other through a platform built on a 3G network. The company's internal voice network is established using the 3G platform to realize voice scheduling, cluster intercom and collaborative operations, fully meeting the needs of the company's internal communications and personnel scheduling and commanding. At the same time, through the 3G wireless private network, the staff can also log in to the company's intranet at any time at any place to complete business acceptance, mail sending and receiving, forwarding official documents, information query, etc., thereby effectively reducing management costs and improving work efficiency;

The remote dynamic video management system includes a monitoring computer and a camera installed on the maintenance or construction site. Carry out real-time supervision, thereby strengthening on-site management and control, realizing dynamic remote management and "walking management", promoting condition-based maintenance and standardized operations, realizing "controllable, under-control, and controllable" safety production, and enhancing enterprise safety production "Controllable, controllable, and under control" capabilities.
