Wireless monitoring system applications in power industry

1. Challenges faced by industrial users

With the continuous development of China's power industry, power system

automation level continues to increase, the substation, substations, high-voltage

transmission lines would have to achieve less people or unattended, in order to improve

production efficiency. How remote monitoring, remote control, security, fire-fighting

and alarm network system, wireless monitoring of organic combination, so that both can

be monitored, the transmission distance of the remote control and image-based

wireless, wired networks, and have generally network alarm network functions, and

input costs reasonable, can be more effective in ensuring the system is stable, the

security technology to a new level. Networking, wireless, remote monitoring is the main

direction of the current surveillance industry.

electrical equipment and substations, timely detection and treatment of accidents, help

to improve the automation of power system security and reliability. There are security

has become a high-voltage transmission lines safety an important part of automation,

high-voltage transmission lines through the security system not only can remotely

inspect the operation of various types of equipment, operational records of personnel,

but also real-time access alarms from the scene of the accident information on the

anomaly may have occurred or timely treatment and preserve the scene of the image

data to provide first-hand information for the analysis of cause of the accident, so that

management and the method of constant electricity sector closely linked with the latest

achievements of science and technology. At the same time remote monitoring system

can also be integrated environment monitoring (ambient temperature, humidity, smoke

alarm, flood alarm), alarm linkage functions.

The characteristics of the power industry for remote monitoring applications,

we provide a viable and efficient wireless monitoring system based operators (China

Telecom, China Unicom, China Mobile) network solutions, full use of the latest computer,

communications, video processing and other aspects of technology, by operators to

offer 3G / 2G network, remote data monitoring and remote video surveillance.

2. Solution Overview

1). Using a wireless network at a fixed location to the substation / high-voltage

transmission lines of video information, monitoring data and environmental

temperature and humidity monitoring data real-time transmission to the command

center;

2). The vehicle mobile transmission, wireless video transmission scheme needs

substation / high voltage transmission line real-time transmission of video surveillance

information to the command center;




-----------------------------------------------------------------------------------------------------------


3). Calls transmit real-time moving image (not the image) and data, and according to the

need to transmit video information of the vehicle by the decoder or decoding card

landing, about to digital information is converted into an analog video signal output to

the big screen;

4).The vehicle systems using vehicle-mounted video information collection pan, can local

video, PTZ control can control modes A control center end software platform, A car

using the control keyboard local control;

5). In the absence of 3G wireless transmission network when the device automatically

jump to the 2G network to continue transmission services;

6). The provincial bureau command center command center or other image can be

real-time scheduling and monitoring data;

7). The field can provide solar power.

3. Architecture programs

3.1 Overall Network diagram of system




-----------------------------------------------------------------------------------------------------------


3.1.1 1st Application : point monitoring

Use Caimore wireless video server through the carrier network substation /

surveillance video transmission of high-voltage transmission line to the command center,

the re-delivery is sent to higher level monitoring platform that allows municipal,

provincial command center in time to see the scene in real time, and to facilitate the

timely dispatch deal with.




-----------------------------------------------------------------------------------------------------------


3.1.2 2nd application: vehicle monitoring

By wireless video server, car camera means video information of high voltage

transmission lines to wirelessly back to the command center video management

platform, and then sent to the superior delivery line video surveillance platform that

allows municipal, provincial command center in time to see the site case for timely

scheduling.




-----------------------------------------------------------------------------------------------------------


3.1.3 3rd Application: Data Monitoring

The system uses CM530 series wireless transparent data transmission terminal,

232/485 data interface via a standard temperature and humidity sensor data,

distribution terminals and other devices collected are transparently transmitted to data

center management platform, specific programs refer to "Electricity, gas (water) remote

meter reading transparent transmission applications. "
