[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The security monitoring device of the present invention can realize long-term or short-term monitoring of the photovoltaic power station through its structure and the system it carries. The short-term monitoring is triggered by the door opening action and can identify the characteristics of the person. If it is the characteristics of the photovoltaic power station staff who has logged in, no monitoring feedback will be given. If it is a stranger, video monitoring can be carried out for a long time after the door is closed, and the video of the stranger will pop up and display in the monitoring room through the cloud to serve as a warning of safety hazards.

[0024] 2. The video monitoring part of the main body of the present invention is arranged on a wall mount, which is arranged above the door by the wall mount, and can be adjusted within a certain range of angles. During installation, it is adjusted according to the height of the door at the entrance of the photovoltaic substation to ensure that monitoring and feature recognition can be completed when people enter the door. A movable seat is arranged on the wall mount through an active groove, and the movable seat can move in a straight line. At the same time, a lifting cover is installed on the movable seat. When long-term monitoring is carried out, the movable seat is in the middle position of the wall mount under the action of a limit spring. Whether the door mount is opened or closed with the door, it will not affect the movable seat. The cover is kept in a low position and will not affect the use of the camera. When short-term monitoring is carried out, the magnetic control module can push the movable seat to the edge of the wall mount. When the door is in a closed state, the cover can be raised to block the end face of the camera to prevent dust from contaminating the glass surface of the camera. When the door is opened, the cover can automatically drop, and the camera is in an open state.

[0025] 3. The present invention sets an infrared transceiver on the wall mount and sets a reflective plate on the door mount. When the door is closed, the door mount is located below the wall mount and the reflective plate is located below the infrared transceiver, so that the infrared transceiver receives a reflected signal and controls the camera to be in an off state. Conversely, when the door mount is detached from the wall mount as the door is opened, the infrared transceiver cannot receive the reflected signal, and the camera can be turned on for video recording and feature recognition.

[0026] 4. The cover plate of the present invention is installed on the lifting plate in a rotatable and movable manner. When the camera rotates, the position of the cover plate can be finely adjusted to ensure that it can fit the camera when it rises. When the cover plate moves up with the slide seat, the slide seat can also compress the elastic airbag, so that the airflow acts on the surface of the cover plate and the surface of the camera to blow away the floating dust and improve the clarity of the camera.

[0043] A reflective plate 16 is provided on the door hanger 15, and when the door hanger 15 is located below the wall hanger 1, the infrared transceiver 14 is triggered by the reflective plate 16. A pushing seat 17 is provided on the door hanger 15, and when the pushing seat 17 passes below the moving seat 7, the sliding seat 18 and the lifting plate 19 can move upward in the moving seat 7.

[0044] A pillar 2 is fixedly mounted on the top of the wall mount 1, and a camera 4 is mounted on the pillar 2 via a rotating member 3, the rotating member 3 is mounted via a damping shaft, and the wall mount 1 is fixed to the wall at the top of the door frame via an angle iron.

[0045] In the security monitoring device of the present invention, the video monitoring part of the main body is arranged on the wall mount 1, and the wall mount 1 is arranged above the door. The camera 4 is installed using the rotating part 3, and can be adjusted in a certain range of angles. During installation, it is adjusted according to the height of the door at the photovoltaic power station to ensure that monitoring and feature recognition can be completed when a person enters the door.

[0046] The movable groove 5 is a through groove arranged on one side of the wall-mounted seat 1, and a guide rod 6 is arranged in the movable groove 5. The movable seat 7 is slidably installed on the guide rod 6 through a slide groove, and the limit spring 8 is connected between the movable seat 7 and the inner wall of the movable groove 5. The electromagnetic seat 13 is located on the side of the back magnet 9.

[0047] In order to ensure the clarity of the camera 4, a movable seat 7 is arranged on the wall mount 1 through an active groove 5. The movable seat 7 can be guided by the guide rod 6 and move linearly in the active groove 5. A lifting cover plate 23 is installed on the movable seat 7. When long-term monitoring is carried out, the movable seat 7 is in the middle position of the wall mount 1 under the action of the limit spring 8. No matter whether the door mount 15 is opened or closed with the door, it will not affect the movable seat 7. The cover plate 23 remains in a low position and will not affect the use of the camera 4. When short-term monitoring is carried out, the electromagnetic seat 13 can be energized so that the back magnet 9 receives magnetic repulsion and pushes the movable seat 7 to the edge position of the wall mount 1. When the door is in a closed state, the cover plate 23 can be raised to block the end face of the camera 4 to prevent dust from contaminating the glass surface of the camera 4. When the door is opened, the cover plate 23 can automatically drop.

[0048] A limiting sleeve 10 is fixedly mounted on the groove wall of the movable groove 5 , and a plug-in 11 is fixedly mounted on the side wall of the movable seat 7 . The limiting sleeve 10 is located on the moving path of the plug-in 11 , and the limiting sleeve 10 and the plug-in 11 can be interference fit.

[0049] When the magnetic force pushes the movable seat 7 to move, the plug-in 11 on the movable seat 7 can be inserted into the limiting sleeve 10, and connected with the limiting sleeve 10 to generate a certain resistance, which helps to position the movable seat 7 and avoids the door closing action not causing the cover plate 23 to rise but causing the movable seat 7 to move.

[0050] The infrared transceiver 14 is installed at the bottom of the wall mount 1, and the door mount 15 is fixed to the top of the door by a clamp or screws. The reflector 16 is fixedly installed on the top surface of the door mount 15, and the infrared signal generated by the infrared transceiver 14 is reflected by the reflector 16.

[0051] The present invention sets an infrared transceiver 14 on the wall mount 1, and sets a reflective plate 16 on the door mount 15. When the door is closed, the door mount 15 is located below the wall mount 1, and the reflective plate 16 is located below the infrared transceiver 14, so that the infrared transceiver 14 receives a reflected signal and controls the camera 4 to be in a closed state. Conversely, when the door mount 15 is separated from the wall mount 1 as the door is opened, the infrared transceiver 14 cannot receive the reflected signal, and the camera 4 can be turned on to perform video recording and feature recognition.

[0052] A cavity is provided in the movable seat 7, and the sliding seat 18 is slidably installed in the cavity of the movable seat 7, a wedge block 20 is fixedly installed at the bottom of the sliding seat 18, and the wedge block 20 is arranged to pass through the bottom of the movable seat 7, and a pushing seat 17 is provided at the top of the door hanging seat 15, and the pushing seat 17 can push the wedge block 20 up along the inclined surface.

[0053] The rise of the cover plate 23 is completed by the pushing seat 17 on the door hanging seat 15. When the device is in the short-time monitoring mode, the person's features are recognized after the door is opened. If it is a feature that has been logged in, the camera 4 is turned off and the electromagnetic seat 13 is kept powered. When the door hanging seat 15 moves to the bottom of the wall hanging seat 1, the pushing seat 17 can push the sliding seat 18 up along the wedge block 20, so that the lifting plate 19 moves up, and the cover plate 23 on it is attached to the surface of the camera 4 to protect it.

[0054] Limiting rails 21 are arranged on both sides of the lifting plate 19 , and movable seats 22 are slidably installed in the two limiting rails 21 , the cover plate 23 is rotatably installed on the movable seat 22 , and positioning plates 24 are arranged on both sides of the movable seat 22 , and the positioning plates 24 are connected to the through grooves of the limiting rails 21 .

[0055] The cover plate 23 of the present invention is installed on the lifting plate 19 in a rotatable and movable manner. This is because the camera 4 can rotate. When the camera 4 rotates, the position of the cover plate 23 needs to be fine-tuned to ensure that it can fit the camera 4 when it rises.

[0056] A screw rod 25 is fixedly connected to the positioning plate 24, and a locking nut 26 is connected to the screw rod 25. The movable seat 22 is positioned in the limiting track 21 through the locking nut 26. The cover plate 23 is tilted, and a support spring 27 is connected between the back of the cover plate 23 and the movable seat 22.

[0057] The cover 23 is arranged on the movable seat 22, so its position adjustment is completed by moving in the limiting track 21 in the movable seat 22. After the adjustment is completed, the locking nut 26 is connected to the screw 25 to generate pressure on the limiting track 21, and the movable seat 22 is fixed by friction, while the cover 23 itself can rotate, and when rising, it fits the surface of the camera 4 under the elastic force of the support spring 27.

[0058] At least six air outlets 29 are arranged on the movable seat 22 , and the elastic airbags 28 are compressed when the slide seat 18 moves upward and inflated when the slide seat 18 moves downward.

[0059] When the cover plate 23 of the present invention moves upward with the slide seat 18, the slide seat 18 can also compress the elastic airbag 28, so that the gas in the elastic airbag 28 is blown out from the air outlet 29. The airflow acts on the surface of the cover plate 23 and the surface of the camera 4 to blow away the floating dust and improve the clarity of the camera 4.

[0060] The security monitoring system disclosed in the present invention includes a signal processing module and a communication module arranged in a controller 12 and a display device arranged in a monitoring room, wherein the display device is provided with a video processing and storage unit and a control unit; further includes a camera module arranged on a wall mount 1; includes an infrared sensor module and a magnetic control module arranged in the wall mount 1; the communication module and the camera module are respectively connected to the signal processing module, and the infrared sensor module and the magnetic control module are simultaneously connected to the signal processing module;

[0061] The camera module controls the switch state through the signal processing module, and the camera module is used to record monitoring video and identify human features, and transmit the identification results to the signal processing module;

[0062] The communication module is used to transmit video signals to the terminal device and receive control signals to transmit them to the signal processing module; the communication module is also connected to the control unit signal to transmit the images collected by the camera module to the display device in the monitoring room;

[0064] The face data comparison module is used to record and compare the face data of the staff of the photovoltaic power station; and transmit the monitoring data of strangers to the analysis and feedback module;

[0065] The analysis and feedback module is used to receive monitoring data of strangers and highlight an area on the display device to display the monitoring video. By popping up the monitoring video of strangers at the entrance on the display device, the monitoring room can obtain abnormal situations at the first time and deal with them in time according to the monitoring situation, so as to prevent the photovoltaic power station from causing unsafe behaviors due to the entry of strangers, and also prevent monitoring and processing when there is no one in the guard room, and also avoid the situation where the guard room staff and strangers cannot be monitored and handled in time at the entrance.

[0066] The infrared sensor module and the magnetic control module are used to control the automatic switch of the camera module by receiving the control signal of the signal processing module.

[0067] The security monitoring device of the present invention is based on the Internet of Things, and is equipped with a security monitoring system, so as to cooperate with the setting of the structure to complete the manual and automatic adjustment of long-term monitoring and short-term monitoring.

[0068] Please see attached Fig.11 , 12, 13, the signal processing module is the core, which can process the video signal and transmit it to the mobile terminal using the communication module, so that people can view the monitoring situation in real time. At the same time, the signal processing module can also receive the control signal transmitted by the communication module and the camera module, set and adjust the monitoring mode, so that the camera 4 works according to the required mode. The control circuit adopts a single-pole double-throw circuit, such as Fig.11 As shown, the camera 4 can be powered directly, in which case it is in a long-term monitoring state. The camera 4 can also be connected to the same circuit as the infrared transceiver 14 and the electromagnetic base 13, in a short-term monitoring mode, in which the operation of the camera 4 is controlled by the infrared transceiver 14.

[0069] The camera module includes a recording module and a feature recognition module. The recording module can generate video in real time when receiving a signal and input the signal into the signal processing module, while the feature recognition module can identify the features of people in the video and transmit it to the face data comparison module for comparing the face data of the staff to determine whether the camera 4 enters the long-term monitoring mode or highlights the stranger monitoring video.

[0070] The communication module includes a Bluetooth module and a remote communication module, which enables the security monitoring equipment to be controlled through a mobile terminal and the real-time monitoring video to be viewed remotely.

[0071] The infrared sensor module includes an infrared transceiver 14, and the magnetic control module includes an electromagnetic seat 13. The two are in the same circuit and are powered on in a short-time monitoring mode to mainly identify the door opening and closing actions and control whether the camera 4 is working and whether the cover 23 is raised or lowered.

[0072] When the security monitoring equipment is in use: first, the video monitoring part of the main body is set on the wall mount 1, which is set above the door using the wall mount 1, and the camera 4 is set towards the inside of the house. The camera 4 is installed using a rotating member 3, and can be adjusted within a certain range of angles. During installation, it is adjusted according to the indoor layout and the height of the door to ensure that monitoring and feature recognition can be completed when a person enters the door. In order to ensure the clarity of the camera 4, a movable seat 7 is set on the wall mount 1 through a movable groove 5. The movable seat 7 can be guided by a guide rod 6 and move in a straight line in the movable groove 5. A lifting cover plate 23 is installed on the movable seat 7. When long-term monitoring is performed, the movable seat 7 is in the middle of the wall mount 1 under the action of a limit spring 8. The cover 23 is kept in a low position and will not affect the use of the camera 4. When short-term monitoring is performed, the electromagnetic base 13 can be energized so that the back magnet 9 receives magnetic repulsion and pushes the movable base 7 to the edge of the wall-mounted base 1. When the door is in a closed state, the cover 23 can be raised to block the end face of the camera 4 to prevent dust from contaminating the glass surface of the camera 4. When the door is opened, the cover 23 can automatically drop. When the magnetic force pushes the movable base 7 to move, the plug-in 11 on the movable base 7 can be inserted into the limiting sleeve 10 and connected with the limiting sleeve 10 to generate a certain resistance, which helps to position the movable base 7 and avoids the door closing action not causing the cover 23 to rise but instead In order to make the movable seat 7 move, the present invention arranges the infrared transceiver 14 on the wall mount 1, and arranges the reflector 16 on the door mount 15. When the door is closed, the door mount 15 is located below the wall mount 1, and the reflector 16 is located below the infrared transceiver 14, so that the infrared transceiver 14 receives the reflected signal and controls the camera 4 to be in the closed state. On the contrary, when the door mount 15 is separated from the wall mount 1 as the door is opened, the infrared transceiver 14 cannot receive the reflected signal, and the camera 4 can be turned on to perform video recording and feature recognition. The rise of the cover plate 23 is completed by the push seat 17 on the door mount 15. When the device is in the short-time monitoring mode, the person's features are recognized after the door is opened. If it is a person who has logged in, the person's features are recognized. When the door mount 15 is moved to the bottom of the wall mount 1, the push seat 17 can push the slide 18 up along the wedge 20, so that the lifting plate 19 moves up, and the cover 23 thereon is fitted on the surface of the camera 4 to protect it. The cover 23 of the present invention is installed on the lifting plate 19 in a rotatable and movable manner. This is in consideration of the fact that the camera 4 can rotate. When the camera 4 rotates the angle, the position of the cover 23 needs to be fine-tuned to ensure that it can fit the camera 4 when it rises. The cover 23 is set on the movable seat 22, so its position adjustment is completed by moving in the limit track 21 in the movable seat 22. After the adjustment is completed, it is connected to the screw 25 using the locking nut 26.The pressure is generated to act on the limit rail 21, and the movable seat 22 is fixed by friction, while the cover plate 23 itself can rotate and fit the surface of the camera 4 under the elastic force of the support spring 27 when rising. When the cover plate 23 of the present invention moves up with the slide 18, the slide 18 can also compress the elastic airbag 28, so that the gas in the elastic airbag 28 is blown out from the air outlet 29, and the airflow acts on the surface of the cover plate 23 and the surface of the camera 4, blowing away the floating dust and improving the clarity of the camera 4.

[0073] It should be noted that the monitoring system protected by the present invention is only set at the entrance of the photovoltaic power station area. The photovoltaic power station is very large, and ordinary video monitoring equipment can be used in other locations.

[0074] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
