Detailed ways

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

Example:

As shown in Figure 1, the figure is the overall structure of the anti-theft system of the insulation head sheath transposition box, the present invention is in order to monitor the safety status of the insulation head sheath transposition box on the street road, when these doors are opened illegally, or In the case of damage, loss, or failure to close due to some reason, it can give an alarm in time and notify the department of the sheath transposition box to deal with it in time, eliminating potential danger and unsafe factors.

The present invention comprises a monitoring center 1 and a monitoring terminal connected through a wireless network, the monitoring terminal is arranged inside the cabinet, and includes a signal acquisition component 21, a processing component 22 and an alarm component 23, and the processing component 22 is connected to the signal acquisition component 21 and the alarm component 23 respectively Communication with the monitoring center 1, the signal acquisition assembly 21 includes a position sensor 211 arranged at the bottom of the box door, a camera 213 arranged inside the box body and an angle sensor 212 arranged on the mechanical lock of the box door, the position sensor 211, the camera 213 and The angle sensors 212 are connected to the processing component 22 respectively, and the signal acquisition component 21 also includes a GPS positioning terminal 214 fixed on the copper bar through a heat-shrinkable sleeve, and the GPS positioning terminal 214 directly communicates with the monitoring center 1 .

Processing assembly 22 comprises the AD converter 221 that is connected with angle sensor 212 and position sensor 211 respectively, the image processor 222 that is connected with camera 213, single-chip microcomputer 223 and wireless communication module 224, and single-chip microcomputer 223 is connected with AD converter 221, image processor respectively. 222. The wireless communication module 224 is connected to the alarm component 23, and the wireless communication module 224 is a GSM or CDMA wireless communication module.

The system mainly consists of two parts:

The monitoring center 1 includes interconnected central processors and wireless communication base stations. There are multiple wireless communication base stations, and the signals cover all monitoring terminals. The main function is to communicate with the monitoring terminals of each remote box to complete the jurisdiction All internal high-voltage insulation head sheath transposition boxes are monitored, and a management interface is provided for operators to perform daily management and statistics.

The monitoring terminal, which is installed in the insulating head sheath transposition box, communicates with the monitoring center 1 wirelessly through GSM or CDMA, and monitors whether the box door is closed through the angle sensor 212. When these sheath transposition boxes If it is damaged, lost or not closed for some reason, it can give an alarm in time.

The wireless communication module 224 is battery-powered, uses the GSM (CDMA) wireless communication module, is installed in the transposition box, is used for the wireless communication with monitoring center 1, considers practicality and feasibility, tentative battery service life 1.5 More than one year, when the battery life is over, it needs to be replaced with a new battery on site.

The real-time electric quantity of GSM (CDMA) wireless communication module battery is reported to monitoring center 1, as the basis of changing new battery.

After the cabinet door is opened or closed, the monitoring terminal reports to the monitoring center 1 through the GSM (CDMA) wireless communication module, and the report delay is about 50 seconds.

Every 36 hours, the monitoring terminal automatically reports the opening and closing status of the cabinet door to the monitoring center 1 by means of a short message through the GSM (CDMA) wireless communication module, and the monitoring center 1 uses this as understanding whether each monitoring terminal is working normally.

The monitoring terminal only monitors the opening and closing status of the door through the angle sensor 212 installed on the box door. Considering that the power consumption of the control door lock is relatively large, the opening of the control door lock is not provided temporarily. The door lock principle of the sheath transposition box Continue to use the existing door lock.

The monitoring terminal fully considers its harsh working environment to ensure long-term reliability. Fully consider the convenience of engineering installation and the maintainability after failure.

In order to distinguish between normal opening and illegal opening of the box door, the person who opens the box must make an appointment registration with the monitoring center 1 through voice guidance. Any opening after reservation registration is regarded as normal opening, and any opening without reservation registration is regarded as illegal opening. .

The invention realizes the passive monitoring of the switch of the outdoor insulation head and sheath transposition box, and can grasp the specific situation of the box in time. For some important insulation head and sheath transposition boxes, the tracking function after the equipment is stolen is increased, so that When the theft scene is not reached in time, it can realize the positioning and tracking of the equipment, and reduce the loss caused by the theft as much as possible. The GPS positioning terminal 214 adopts battery-driven technology, which can realize positioning at the same time, and provide monitoring of switching value, vibration and tilting action. All collectors are built-in, about the size of a mobile phone, concealed installation, and support remote startup and shutdown, which greatly improves the protection of important equipment. The equipment can also be used for mobile routing monitoring of important equipment. The combination of this product and PATROUNSLOCK products It greatly improves the availability of the system, provides customers with a complete anti-theft monitoring network, and is widely used in the anti-theft of important distributed equipment.
