Description

Technical Field

[0001] This invention relates to the field of monitoring system technology, and more specifically, to an intelligent photovoltaic monitoring device. Background Technology

[0002] Solar energy has become a focus of attention due to its unique advantages. Abundant solar radiation is an important energy source—inexhaustible, pollution-free, inexpensive, and freely usable by humankind. Up to 800 MWh of solar energy reaches the Earth's surface every second. If 0.1% of the solar energy on the Earth's surface were converted into electricity at a conversion rate of 5%, the annual power generation would reach 5.6 × 10^12 kilowatt-hours, equivalent to 40 times the world's energy consumption. Because of these unique advantages, since the 1980s, the types of solar cells have continuously increased, their applications have broadened, and the market size has gradually expanded. Currently, 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 real-time information to the monitoring rooms of various law enforcement agencies. However, as the number of surveillance cameras installed in cities increases, the power supply method relies solely on the power grid. How to solve the problem of relying solely on the power grid to power surveillance cameras and reduce the laying and wiring of electrical cables is a problem that needs to be addressed.

[0004] Invention Patent Content

[0005] The technical problem this invention patent aims to solve is that existing surveillance cameras have a single power supply method, are cumbersome to install with cables, and suffer from unstable power grids affecting monitoring information and increasing the burden on the power grid. The invention provides an intelligent photovoltaic camera product that can generate and store electricity without interruption. Photovoltaics utilize abundant outdoor sunlight resources to generate a large amount of DC electricity, and excess energy can be stored in batteries to ensure that the camera is powered without interruption and that monitoring information is not interrupted, thus using green energy.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An intelligent photovoltaic monitoring device includes: a solar panel, an energy storage module, a power management module, a central processing unit, a data acquisition 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 generates direct current to charge the camera and energy storage module;

[0010] Energy storage modules include: lithium batteries;

[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 to process and manage the information.

[0012] The power management module is used to manage the power generation of the solar panels and the charging and discharging of the lithium batteries.

[0013] The image processing module is used to process the image information from 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 the SOC of the lithium battery is detected to be in the range of 25% to 50% of the total capacity, the power management module will execute a continued charging strategy to control the solar panel to continue charging the lithium battery.

[0018] When the lithium battery's SOC is detected to be between 51% and 95% of its total capacity, the power management module sends a request to the central processing unit. Upon receiving the request, the central processing unit calculates the overall actual power consumption of the intelligent photovoltaic monitoring device.

[0019] When the total actual power consumption is less than 50% of the total maximum power consumption, the central processing unit will issue a continued charging strategy to the power management module, which will then execute the continued charging strategy to control the solar panels to continue charging the lithium battery.

[0020] When the total actual power consumption is greater than or equal to 50% of the total maximum power consumption, the central processing unit will issue a command to enable the float charging mode to the power management module, which will then execute the float charging mode on the lithium battery.

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

[0022] When the SOC of the lithium battery exceeds 95% of the total capacity, the power management module sends a request to the central processing unit. After receiving the request, the central processing unit calculates the total actual power consumption of the intelligent photovoltaic monitoring device.

[0023] When the total actual power consumption is less than 50% of the total maximum power consumption, the central processing unit will issue a command to enable the float charging mode to the power management module, which will then execute the float charging mode on the lithium battery.

[0024] When the total actual power consumption is greater than or equal to 50% of the total maximum power consumption, the central processing unit will issue a command to the power management module to enable or disable the charging mode, and the power management module will then enable or disable the charging mode for the lithium battery.

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

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

[0027] When the total actual power consumption is greater than or equal to 70% of the total maximum power consumption, a command to allow the request is sent to the power management module;

[0028] When the total actual power consumption is less than 70% of the total maximum power consumption, a command 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 executes the simultaneous use of the solar panel and lithium iron phosphate battery to power the acquisition module.

[0030] Furthermore, when the power management module detects that the temperature of the lithium battery is greater than or equal to 60°C, it does not send a request to the central processing unit and directly cuts off the lithium battery circuit.

[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] Users set the required device parameters on the terminal and transmit them to the WIFI communication module. The WIFI communication module packages the user's required settings parameters and sends them to the central processing unit. After receiving the parameters, the central processing unit makes corresponding decisions and sends instructions to the corresponding modules.

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

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

[0035] Furthermore, the solar panel is embedded in 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 enables the monitoring camera to operate offline from the power grid, reducing the burden on the power grid, using green energy, and reducing pollution. In addition, the product integrates multiple functional modules and processing units to ensure the stable operation of the monitoring system and prevent the loss of monitoring information.

[0058] Furthermore, when the power management module detects that the actual power generation of the solar panel reaches 40-80% of its maximum power generation, it sends a request to the central processing unit to simultaneously call upon the solar panel and the lithium iron phosphate battery to power the acquisition module. After reading the total actual power consumption of the device, the central processing unit sends an instruction to the power management module to allow or deny the request according to the first strategy, and the power management module executes the instruction.
