Description

Technical Field

[0001] The present invention relates to the technical field of monitoring systems, and in particular to an intelligent photovoltaic monitoring device. Background Art

[0002] Solar energy has become the focus of attention due to its unique advantages. The abundant solar radiation energy is an important energy source, which is inexhaustible, pollution-free, cheap, and freely available to humans. The energy of solar energy reaching the ground every second is as high as 800MWh. If 0.1% of the solar energy on the earth's surface is converted into electrical energy, with a conversion rate of 5%, the annual power generation can reach 5.6×10^12 kilowatt-hours, which is equivalent to 40 times the world's energy consumption. It is precisely because of these unique advantages of solar energy that after the 1980s, the types of solar cells have continued to increase, the scope of application has become increasingly broad, and the market scale has gradually expanded. At present, people are gradually applying solar energy to various fields.

[0003] With the growth of the Internet and the Internet of Things, smart cities are becoming increasingly popular. Urban road safety and life safety have become essential concerns. Intersection and street monitoring systems can transmit current information to the monitoring rooms of various law enforcement units in real time. However, the number of surveillance cameras installed in cities has increased, and the power supply method is only dependent on the power grid. How to solve the single power supply method of surveillance cameras from the power grid and reduce the laying and stringing of wires is a problem that needs to be solved.

[0004] Invention patent content

[0005] The technical problem to be solved by the patent of this invention is that the existing surveillance cameras have a single power supply mode, cumbersome wiring and installation, unstable power grid areas affect monitoring information, and increase the burden on the power grid. Therefore, an intelligent photovoltaic camera product that can generate electricity uninterruptedly and store electricity is provided. Photovoltaics use the abundant outdoor light resources to generate a large amount of direct current, and the excess energy can also be stored in batteries to ensure that the camera is powered on and the monitoring information is not interrupted, using green energy.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] An intelligent photovoltaic monitoring device, comprising: a solar panel, an energy storage module, a power management module, a central processing unit, a collection module, an image processing module, a WIFI communication module, a user terminal, and a storage module;

[0008] The acquisition module includes: a camera;

[0009] The solar panel is used to convert light energy into electrical energy, and emit direct current to charge the camera and the energy storage module;

[0010] The energy storage module includes: lithium battery;

[0011] The central processing unit is used to receive information from the power management module, the image processing module, and the WIFI communication module, and process and manage the information;

[0012] The power management module is used to manage the power generation of the solar panel and the charging and discharging of the lithium battery;

[0013] The image processing module is used to process the image information of the acquisition module;

[0014] The storage module includes: a memory card;

[0015] The WIFI communication module is used to access the Internet and is responsible for information transmission between the user terminal and the central processing unit.

[0016] Furthermore, the power management module manages the charging and discharging of the lithium battery, including:

[0017] When it is detected that the SOC of the lithium battery reaches 25% to 50% of the total power, the power management module will execute the continued charging strategy and control the solar panel to continue charging the lithium battery;

[0018] When it is detected that the SOC of the lithium battery reaches the range of 51% to 95% of the total power, the power management module will send a request to the central processing unit. After receiving the request, the central processing unit calculates the overall actual power consumption of the intelligent photovoltaic monitoring device:

[0019] When the overall actual power consumption is less than 50% of the overall maximum power consumption, the central processing unit will send a continued charging strategy to the power management module, and the power management module will execute the continued charging strategy to control the solar panel to continue charging the lithium battery;

[0020] When the overall actual power consumption is greater than or equal to 50% of the overall maximum power consumption, the central processing unit will issue a floating charge mode start instruction to the power management module, and the power management module will perform the floating charge mode on the lithium battery;

[0021] Furthermore, the power management module manages the charging and discharging of the lithium battery, including:

[0022] When it is detected that the SOC of the lithium battery exceeds 95% of the total power, the power management module will send a request to the central processing unit. After receiving the request, the central processing unit calculates the overall actual power consumption of the intelligent photovoltaic monitoring device:

[0023] When the overall actual power consumption is less than 50% of the overall maximum power consumption, the central processing unit will issue a floating charge mode start instruction to the power management module, and the power management module will perform the floating charge mode on the lithium battery;

[0024] When the overall actual power consumption is greater than or equal to 50% of the overall maximum power consumption, the central processing unit will issue an instruction to start the stop charging mode to the power management module, and the power management module will execute the stop charging mode for the lithium battery.

[0025] Furthermore, when the power management module monitors that the actual power generation of the solar panel reaches 40% to 80% of its maximum power generation, a request is sent to the central processing unit to simultaneously call on the solar panel and the lithium iron phosphate battery to power the acquisition module. After reading the overall actual power consumption of the device, the central processing unit sends an instruction to allow or reject the request to the power management module according to the first strategy, and the power management module executes the instruction.

[0026] Furthermore, the first strategy is as follows:

[0027] When the overall actual power consumption is greater than or equal to 70% of the overall maximum power consumption, sending an instruction to allow the request to the power management module;

[0028] When the overall actual power consumption is less than 70% of the overall maximum power consumption, an instruction to reject the request is sent to the power management module.

[0029] Furthermore, when the power management module detects that the actual power generation of the solar panel is less than or equal to 30% of its maximum power generation, it does not send a request to the central processing unit, but directly calls the solar panel and the lithium iron phosphate battery to power the collection module at the same time.

[0030] Furthermore, when the power management module detects that the temperature of the lithium battery is greater than or equal to 60° C., no request is sent to the central processing unit, and the circuit of the lithium battery is directly cut off.

[0031] Furthermore, the WIFI communication module is used to access the Internet and is responsible for information transmission between the user terminal and the central processing unit, including:

[0032] The user sets the required device parameters in the terminal and passes them to the WIFI communication module. The WIFI communication module packages the setting parameters required by the user and sends them to the central processing unit. After receiving the parameters, the central processing unit makes corresponding strategies and sends instructions to the corresponding modules.

[0033] Furthermore, the image processing module is used to process the image information of the acquisition module, including:

[0034] The image processing module processes the image information transmitted by the acquisition module according to the screen resolution parameters set by the user, and sends the processed image information to the central processing unit, which packages the image information and writes it to the storage card, or transmits it to the user terminal through the WIFI communication module.

[0035] Furthermore, the solar panel is embedded on the top of the camera.

[0036] The beneficial effects are as follows:

[0037] The product provided in this application can be used for urban road and street monitoring. It can enable monitoring cameras to operate independently of the power grid, reduce the burden on the power grid, use green energy, and reduce pollution. The product integrates multiple functional modules and processing units to ensure that the monitoring system operates stably and monitoring information is not lost. BRIEF DESCRIPTION OF THE DRAWINGS
