Technical Field

[0001] The utility model relates to the technical field of photovoltaic power station monitoring, and in particular to a photovoltaic power station security system based on a common camera. Background Art

[0002] At present, most photovoltaic power stations adopt unattended operation mode. The unattended monitoring system of photovoltaic power stations usually includes functions such as video monitoring, environmental monitoring, equipment status monitoring, and safety protection. It can monitor the operation status, environmental parameters, equipment status and other information of the power station in real time, and transmit it to the monitoring center through the network to realize remote monitoring and management of the power station. At the same time, the unattended photovoltaic power station also needs to establish a complete emergency plan and fault handling mechanism to ensure timely response and handling in the event of a fault or abnormal situation.

[0003] In terms of video surveillance, we usually purchase ready-made integrated cameras and install them at various monitoring locations. The cameras age quickly due to long-term exposure to light, so regular maintenance requires replacing a large number of cameras. In addition, separate wiring is required for communication and power supply between cameras, which increases the installation and maintenance costs of video surveillance. For this reason, we propose a photovoltaic power station security system based on ordinary cameras to solve the above problems. Utility Model Content

[0014] It can be seen from the above technical scheme that the present application provides a photovoltaic power station security system based on an ordinary camera. The utility model can be installed at any position of the photovoltaic power station. Specifically, the camera is installed on the mounting frame. After the mounting frame is installed, the external connecting line is connected to any photovoltaic panel circuit. During specific use, the transformer converts the electric energy generated by the photovoltaic panel into a stable voltage to supply two power supplies for charging. Specifically, when one is full, the other is charged. When one is full and the other is still in use, the charging is stopped. The power supply between the two power supplies is controlled by a dual power automatic switching switch. The data collected by the camera can be sent to a remote receiving end in real time, or a collection node can be set to send the collected information once every period of operation to complete the video monitoring work of the photovoltaic power station.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Through the installation of power distribution cabinets, transformers and external connecting wires, the voltage in the photovoltaic system can be stabilized by using transformers, and the existing power of the photovoltaic power station can be used to supply video acquisition work, without the need for wiring installation;

[0017] 2. Through the setting of the charger and dual power supply, the two power supplies are charged and used alternately to avoid power outages at night. This can not only increase the standby time of the system, enable long standby time on rainy days, but also enable the battery to be fully charged and discharged, thus increasing the battery life;

[0018] 3. Through the setting of the communication device, the collected video information is transmitted wirelessly, so that the system can be installed in every corner of the photovoltaic power station without increasing the installation cost of the system;

[0019] 4. Through the setting of detachable camera and mounting plate, this system can achieve the detection purpose by installing only ordinary camera. When the camera is damaged, ordinary camera can be purchased to reduce the system maintenance cost.

[0020] To sum up, in the present invention, only ordinary cameras need to be installed to achieve the purpose of installing the system at any location in the photovoltaic power station, thereby realizing all-round video monitoring and low installation cost. When components in the system are damaged, only the corresponding components need to be replaced, and the subsequent maintenance cost is low, thereby reducing the management cost of the photovoltaic power station.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0028] See also Figure 1-4, a photovoltaic power station security system based on an ordinary camera, the present application is mainly used in the monitoring supporting system of a photovoltaic power station that can provide electric energy intermittently, specifically, it includes a mounting frame 1, the mounting frame 1 is made of stainless steel or aluminum alloy, because the present system is mainly installed outdoors with high light intensity, the outer side of the mounting frame 1 is white sunscreen paint to prevent direct sunlight from causing the temperature inside the mounting frame 1 to be too high, causing the line to age too quickly, a distribution cabinet 4 is installed on one side of the mounting frame 1, the distribution cabinet 4 in the present application is a three-proof distribution cabinet, mainly used outdoors, and can be waterproof, anti-theft and windproof (prevent wind and sand from entering the distribution cabinet 4), the specific three-proof distribution cabinet can refer to the prior art, the distribution cabinet 4 is installed with a transformer 5, the present application The transformer 5 in the application is a small solar transformer, which mainly converts the electricity generated by the nearby solar panels into a stable voltage for use in the system. One end of the transformer 5 is connected to the second row of wires 12, and the second row of wires 12 is detachably connected to the external connection wire 16, and the external connection wire 16 extends to the outside of the mounting frame 1. The present application divides the wires connected to the outside into two sections, which can achieve two advantages. The first point is that the external wires are located outdoors and are seriously aged. When regular maintenance is performed, the external connection wire 16 can be directly replaced. The second point is that some photovoltaic power stations need to be regularly maintained and cleaned, which is easy to cause damage to the external cables. When the cables are damaged, only the external connection wire 16 needs to be replaced, which reduces the maintenance cost;

[0029] The transformer 5 is connected to a charger 18, and a dual power supply 19 is installed on the charger 18. When in use, the charger 18 uses the stable voltage of the transformer 5 to charge two power batteries. When in use, one battery supplies power and the other battery charges. When one battery is full and the power of the other battery has not been used up, the charging is stopped until the power of the battery is used up, and then the dual power automatic switching switch is used to switch to the other battery for power supply. The charger 18 then charges the power battery whose power has been used up. This design can not only ensure that the battery is fully charged and discharged every time it is used, thereby improving the battery life, but also can supply power at night or when other solar panels cannot operate normally. The dual power automatic switching switch can refer to the existing structure for details. The device can automatically switch the circuit instantly when the power supply is insufficient, and the normal use of the electrical equipment is not affected when switching the circuit. The dual power supply 19, the charger 18 and the transformer 5 are all connected to a controller 21. The control of the dual power supply 19, the charger 18 and the transformer 5 is controlled by the controller 21. The control of the dual power supply 19, the charger 18 and the transformer 5 is all prior art. The technicians should understand the control method, so this application will not repeat it.

[0030] The controller 21 is also connected to a storage unit 20, a communication device 3 and a first row of cables 2. The storage unit 20 is mainly used to store video information, which can be sent in real time through the communication device 3 or at a scheduled time. In this application, video information is sent to a node every 15 minutes or 30 minutes. Under the same battery power, intermittent startup of the communication device 3 can extend the battery life. The first row of cables 2 extends to the top of the mounting frame 1. A mounting groove 9 is fixed to the top of the mounting frame 1. In the specific design, the mounting groove 9 is arranged vertically downward to minimize direct sunlight. A camera 11 is detachably installed in the mounting groove 9. The camera 11 is detachably connected to the first row of cables 2. The camera 11 in this application is an ordinary camera 11. When the camera 11 is aged, it can be removed and replaced with a new camera 11, thereby reducing the replacement cost of the camera.

[0031] In the present invention, a cable outlet is provided at one side of the bottom of the mounting frame 1, and a cover 17 is installed at the cable outlet. A threading hole 15 is provided on the cover 17, and the external connection line 16 extends to the outside of the mounting frame 1 through the threading hole 15. The arrangement of the cable outlet facilitates the connection between the second cable 12 and the external connection line 16, and hides the connection position in the mounting frame 1, thereby avoiding the external exposed connection part;

[0032] In order to further improve the sealing performance of the mounting frame 1, a rubber layer 14 is provided at the threading hole 15, and the external connecting wire 16 passes through the rubber layer 14. Specifically, when connecting, the rubber layer is glued to the threading hole 15 with glue, and a small hole is drilled in the rubber layer, and the external connecting wire 16 can be passed through the small hole, thereby improving the sealing performance of the mounting frame 1.

[0033] In some embodiments, in order to improve the connection efficiency of the cables, the first cable 2 and the camera 11 are connected through the first connecting socket 7, and the second cable 12 and the external connecting cable 16 are connected through the second connecting socket 13. The connection between the first connecting socket 7 and the second connecting socket 13 is in the form of plug-in, so the connection is more convenient.

[0034] In some embodiments, a plurality of studs 10 are provided in the mounting groove 9, and a mounting plate 6 is provided at the mounting portion of the camera 11. If the camera 11 does not have a mounting plate 6, a mounting plate 6 can be provided at the bottom connection position of the camera 11 in advance. The mounting plate 6 is provided with a plurality of through holes corresponding to the studs 10. The studs 10 pass through the through holes and are threadedly sleeved with nuts. The camera 11 can be removed by removing the nuts to complete a new installation. During the specific installation, in order to reduce the impact of direct sunlight on the camera 11, the first row of cables 2 is located at one end of the camera 11 and is spirally arranged.

[0035] In some embodiments, the first cable 2 is disposed in a spiral shape at one end of the camera 11 , which facilitates taking out and putting in the first cable 2 in the mounting frame 1 , and can also act as a buffer when the camera 11 accidentally slips off.

[0036] In some embodiments, a plurality of brackets 8 for supporting the first array of cables 2 are disposed in the mounting frame 1 to reduce the contact between the first array of cables 2 and the mounting frame 1 , thereby reducing the aging of the cables.

[0037] In some embodiments, the controller 21 is also connected to a power failure alarm device, which can promptly alarm and repair when a problem occurs in the external connection line 16 or other circuit of the device.

[0038] It can be seen from the above technical scheme that the utility model can be installed at any position of a photovoltaic power station. Specifically, the camera 11 is installed on the mounting frame 1. After the mounting frame 1 is installed, the external connecting line 16 is connected to any photovoltaic panel circuit. When in specific use, the transformer 5 converts the electric energy generated by the photovoltaic panel into a stable voltage to supply two power supplies for charging. Specifically, when one is full, the other is charged. When one is full and the other is still in use, the charging is stopped. The power supply between the two power supplies is controlled by an automatic dual power switching switch. The data collected by the camera 11 can be sent to a remote receiving end in real time, or a collection node can be set to send the collected information once every period of operation to complete the video monitoring work of the photovoltaic power station.
