Solar remote monitoring system is a technology that can track and manage solar devices from a distance. Solar wireless monitoring system mainly consists of three subsystems: solar power supply system, wireless video transmission system, and video monitoring system. Next, the inverter shop will bring you relevant content about solar remote monitoring system.
Composition of solar power supply system
Solar remote monitoring system is a technology that allows remote tracking and management of solar devices. Solar power supply system plays a vital role in solar remote monitoring system. Solar power generation system consists of a solar cell group, solar controller, and battery (group). If the output power supply is AC 220V or 110V, it is complementary to the mains power, and an inverter and mains power intelligent switch is also required.
Solar cell array (Solar panel)
This is the core part of the solar photovoltaic power generation system. Its main function is to convert solar photons into electrical energy to drive the load to work. Solar cells are divided into monocrystalline silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon solar cells. Because monocrystalline silicon cells are more durable than the other two, have a long service life (generally up to 20 years), and have high photoelectric conversion efficiency, they have become the most commonly used batteries.
Solar charge controller
The main job of the solar charge controller is to control the state of the entire system while protecting the battery from overcharging and over-discharging. It also has a temperature compensation function in places where the temperature is particularly low.
Solar deep cycle battery pack
As the name implies, the battery is used to store electricity, mainly storing the electricity converted by solar panels. It is generally a lead-acid battery and can be recycled many times.
In the entire monitoring system, some equipment needs to provide 220V, and 110V AC power, while the direct output of solar energy is generally 12VDC, 24VDC, and 48VDC. Therefore, to provide power for 22VAC, and 110VAC equipment, a DC/AC inverter must be added to the system to convert the DC power generated by the solar photovoltaic power generation system into AC power.
The role of different parts in solar remote monitoring system
The solar power supply subsystem consists of solar cell modules, wind turbines, colloidal batteries, and intelligent charge and discharge controllers. The electric energy generated by solar power generation is stored in the battery (charging); when electricity is needed, turn on the controller switch, connect the load, and supply the electric energy in the battery to the load (discharging). The main function of the intelligent controller is to manage the charging and discharging of the battery. When the battery power supply is insufficient during working hours, the controller automatically cuts off the load power supply and performs over-discharge and charging protection on the battery.
The battery is the energy source required to maintain the system in the absence of sunlight. When there are continuous rainy days, the battery needs to have enough power to maintain the continuous operation of the entire system. Since solar colloidal batteries are expensive, it is not possible to consider that there will be several long rainy days in a year and increase the battery configuration of the system. In this way, the battery configuration of the system is in a waste state most of the time. The result of configuring too many batteries will inevitably lead to a significant increase in costs. Therefore, the solar power supply application system should allow for a low probability of power shortage, and the battery-independent power supply time is generally 4-10 days.
The wireless video transmission subsystem consists of a digital bridge, 4G wireless network, COFDM, etc.
The video monitoring subsystem consists of cameras, terminal video management equipment (such as digital hard disk recorders), etc., and other auxiliary functions can be added as needed, such as: front-end sound pickup, front-end speakers, front-end recording, front-end sensing, video analysis, wireless broadcasting, motion detection, wireless signal relay station, etc.
The solar control system has many advantages: environmental protection and energy saving, no need to dig trenches or set up power racks, no need for a large number of wires, no need for power transmission and transformation equipment, short construction period, no power consumption and no electricity charges, no geographical restrictions, low maintenance costs, low voltage, no risk of electric shock, flexible movement, etc.
Current data transmission methods for solar monitoring
Based on the microwave network of wireless bridges and the 3G/4G network of wireless platform operators, wired transmission can be selected according to actual conditions and needs.
Working principle of the solar remote monitoring system
When the sunlight is strong, the current generated by the solar photovoltaic module will converge to the controller, which will monitor the power supply. The solar photovoltaic module supplies power to the video surveillance module through the controller and stores the excess power in the energy storage system.
When the sunlight is weak and the power generation of the solar energy storage unit solar panel cannot meet the energy required for video surveillance, the load will not only obtain energy from the solar energy storage unit panel, but the energy storage system will also be in a discharging state to meet the stable operation of video surveillance. When the sunlight conditions are poor at night, on cloudy days, etc., the energy storage system will be used to power the video surveillance.
Why use solar energy for outdoor remote monitoring?
In electromechanical engineering, the simplicity and complexity of equipment installation and wiring, and the convenience and difficulty of later maintenance are also issues of concern to many owners and contractors. Compared with traditional cable power supply, solar power supply saves a lot of complicated wiring. Simple installation can be completed by simply installing the load on the column: later maintenance only requires cleaning the solar panels and replacing the batteries.
Due to the large number of cameras deployed in the entire monitoring system and the long mileage involved, if a traditional direct buried cable power supply is used, considering the voltage drop along the cable, a relatively thick copper core cable must be used, which increases the cost a lot. If solar power supply is used, the intermediate cable and its laying process are omitted, which has a good cost-effectiveness.
