Description of drawings

The following is a brief description of the content expressed in each drawing in the description of the present invention and the marks in the figure:

Figure 1 is a schematic diagram of the security system;

The marks in the above figures are: 1. Master station system; 2. Substation system.

Detailed ways

As shown in Figure 1, the substation security system includes a main station system 1 installed in the monitoring center and substation systems 2 installed in each substation. The main station system 1 communicates with each substation system 2 through the network, so that the main station system of the monitoring center The station system 1 establishes a communication relationship with the substation system 2 of each substation to realize an unmanned monitoring substation security system.

The master station system 1 includes a master station data conversion unit connected to the network, a display and a signal input device connected to the master station data conversion unit; the master station data conversion unit is used for converting receipts and data conversion, and sends the converted signal through a cable To the display, the display is used to display the monitoring images collected by the cameras of each substation, as well as the data parameters adopted by other equipment. The signal input equipment includes microphones and control buttons. In case of an intruder, you can warn by shouting, and the control button can control the device, switch the screen and so on.

The substation system 2 includes a substation data conversion unit connected to the network, and a monitoring unit connected to the substation data conversion unit. The substation data conversion unit is used to convert the receipt and data conversion, and will receive the signal of the monitoring unit through the cable and send On the network, the monitoring unit includes some or all of cameras, access controllers, access card readers, electronic fence alarm units, infrared radiation units, temperature measurement units and infrared dual-identification detectors.

The access control controller and the access control card reader are installed on the gate at the entrance of the substation to control the intruders. The infrared double-screen detector and the infrared interjection unit are installed at the entrance of the substation to monitor whether there are intruders. The electronic fence alarm unit Installed on the fence of the substation to monitor whether there are intruders. The temperature measurement unit is installed in the main control room, switch room, capacitive and arc suppression coil room to monitor equipment and indoor temperature, monitor whether the equipment is working normally, and arc suppression. There is also an infrared dual detector at the entrance of the coil room to monitor whether there is an intruder.

In addition, the monitoring unit is also equipped with a patrol camera mechanism and a loudspeaker. The patrol camera mechanism includes a patrol track set in the substation, a movement mechanism installed on the track, and a camera unit installed on the movement mechanism, which is used for patrol monitoring and improves monitoring. , The loudspeaker is used to shout in the substation. When an intruder is found, it can be warned through the loudspeaker. The data conversion unit of the main station and the data conversion unit of the substation are equipped with storage units, which can store monitoring data for later monitoring.

The display of the main station system includes a monitoring display that displays the images collected by each camera in the substation system, a data display that displays the data collected by the monitoring unit, and a warning screen for special conditions; when the signal collected by the monitoring unit reaches the preset alarm value , the warning screen will display the surveillance image of the camera at that place. If there is no camera at that place, the patrol camera mechanism will cancel the preset patrol track, move to this place first to collect images and display them on the warning screen in a special state, until the alarm is cancelled, the patrol camera Agencies are still patrolling according to pre-designed patrol trajectories. If the monitoring unit collects multiple signals and reaches the preset alarm value, the warning screen in the special state is divided into multiple screens of equal size, and the alarm images of each place are displayed respectively.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods, as long as various insubstantial improvements are adopted in the method concept and technical solutions of the present invention, or there is no improvement Directly applying the conception and technical solutions of the present invention to other occasions falls within the protection scope of the present invention.
