Description

Power control system of network equipment and its method {REMOTE POWER CONTROL SYSTEM OF NETWORK EQUIPMENT FOR AND METHOD THEREOF}

The present invention relates to a power control system and method for network equipment capable of recovering a failure by automatically resetting power when a failure occurs by grasping the status of a network equipment such as a CCTV located in a remote location in real time.

In general, CCTV (closed circuit television) connects the transmission and reception of images by wire or wirelessly, and is called a closed circuit television because it cannot be arbitrarily received except for a reception target.

Such CCTVs are widely used for industries other than broadcasting TV, education, medical, traffic control surveillance, disaster prevention, and transmission of image information within the company. There is an increasing number of installations for crime prevention, such as installing CCTVs in the same danger zone. This rapid increase in CCTV installations has been proven to have the effect of preventing and deterring crimes, the ease of securing crime scenes and arresting criminals, reducing citizens' fears, and supplementing limited police and crime prevention personnel. Because.

In some people, the portrait rights of ordinary citizens may be infringed due to CCTV, and their privacy may be seriously exposed, as well as problems such as that individual citizens may be imprinted as potential criminals. However, despite these problems, the CCTV system is used as a means of determining the cause of civil complaints, cracking down on traffic guidance, preventing crimes, and identifying the path of the criminals, thereby substantially reducing the incidence of crimes or civil complaints. Installation is on the rise.

In particular, in recent years, a number of cameras have been installed depending on the purpose and target of surveillance, such as a life crime prevention system, an object automatic tracking system, an illegal parking/stop control system, an unmanned road crime control system, an unmanned signal and speed control system, an illegal garbage discharge control system, etc. Examples of constructing intelligent CCTV systems are increasing.

However, since equipment such as field surveillance CCTV is individually distributed or installed in the field, if an error occurs in the equipment, the management personnel must visit the site and restore the power, so unnecessary time is wasted during equipment inspection and restoration. And there was a problem in that cost consumption occurs.
