1. Introduction
As we all know, the personal safety of electric power
construction site is the basic requirements for safe
production. Part of the construction site, some of the
work team, one-sided pursuit of speed of construction to
the neglect of the safety management, the problem of
illegal operations and inappropriate measures occur at
any time, leaving many security risks, these problems
have been plaguing the safety and production of
electricity. Safety oversight becomes the focus of the
work of production safety, only to strengthen the
monitoring of security operations at the scene, in order to
effectively control the occurrence of the accident.
Monitoring of the power system is still generally the
on-site supervision of security p ersonnel and fixed within
the scope of on-site monitoring, but most of the power
construction work in the outdoors, mountains and
pastoral areas and away from the city area, the safety of
operations at the scene cannot be effective monitoring
and protection. In order to ensure the personal safety of
the construction site, the traditional methods of
surveillance and security managers rely on on-site
inspection, in recent years, supervision of rural power
grids and city power grids due to limited manpower, has
been unable to meet over a broad area of a new situation.
Therefore, to strengthen the means of power construc tion
site safety supervision is important. Improve the level of
safety production supervision, is the first task placed the
safety supervision department of the Power Supply
Bureau. The events of a Power failure, some staffs lack
of the technical level, rather than cannot quickly
determine the point of failure. Not only affects th e user a
reliable power supply, and the extended outage time.
Therefore, the necessary research and development of a
mobile monitoring device, it can move with the job site
and are subject to monitoring, so as to achieve effective
control of field operations. With digital video
compression, transmission, storage and playback as the
core of a new generation of video surveillance system,
this system is known as network digital video
surveillance systems. The system has some of the
advantages of the traditional monitoring system does not
have, such as multi- functional, anti-jamming is strong,
easy to maintain, easy to preserve. The digitization of
information, networking and intelligent is a trend of
social development, Therefore, the system for a mobile
intelligent field operations monitoring devices, video
compression and monitoring functions are concentrated
into a small device, to provide reliable and uninterrupted
power supply, Internet directly through the 3G network
connection, plug and look to achieve on-site monitoring.
Ensure scene safety operations thousands of miles away,
you can also remotely monitor and viewing[1].

security managers in front of the computer terminal to
monitor any construction site monitoring equipment, can
also be monitored through intelligent mobile phone
terminals, observed at any time to master the con-struc-
tion site of the security situation, especially the scene
violation is found, can be promptly corrected to protect
the construction site safety management. When the
construction site, such as unplanned failures, have
technical personnel and remote technical support, the
construction site of the monitoring station can record
important information as a future security. The device
has the following characteristics:
1) High image quality. It can work in a situation
complicated geographical conditions of the day and night,
mountain, are able to ensure the image is clear, stable,
true, in a timely manner to reflect the situation of the
construction site.
2) Without cable restrictions. Transmission over 3G
communication network, monitoring range, can any one
point of view of 360-degree monitor the construction site,
