Description

Solar panel wireless power sensing device and monitoring system

The present invention is a sensing device, more particularly, a solar panel sensing device using an electric field or a magnetic field to wirelessly drive a power source, and can be applied to the application of solar panel function tracking, monitoring and troubleshooting.

The current global oil and household oil prices remain high, has become a common phenomenon. Oil and coal, due to the overpopulation and the large-scale use of human beings, have reduced the number of years that human beings use oil, and the earth has also suffered various environmental and ecological damages due to excessive energy use. Therefore, in order to cope with the rapid reduction of oil and coal, while the energy demand is increasing, human beings have to develop other alternative energy sources.

At this time is the best time to use renewable energy. The energy radiated from the sun is quite large. It is estimated that nearly 50% of the solar radiation can be absorbed and used by the surface, so as long as it can be used more, solar energy has the potential to become a real permanent energy source , The use of solar panels to absorb solar energy has become a very popular topic in recent years. Under the continuous research and improvement, the efficiency and scope of use of solar panels have become more and more advanced.

A solar panel refers to a facility that converts solar energy into direct current electricity by using the photovoltaic effect of optoelectronic semiconductor materials. Currently, the semiconductor materials used for power generation mainly include: monocrystalline silicon, polycrystalline silicon, amorphous silicon and cadmium telluride, etc. As countries have been actively promoting the application of renewable energy in recent years, the photovoltaic industry has developed rapidly, and solar panels can be installed on the ground on a large scale. As a photovoltaic power station, it can also be placed on the roof or outer wall of a building to form a photovoltaic building integration.

However, when there are a large number of solar panels to form a photovoltaic power station, it is necessary to set up large wires at the same time, and pay attention to the temperature, humidity and voltage of the solar panels. If a short circuit occurs or the temperature rises and burns, it will cause huge losses. During the operation, the staff is usually monitored regularly on site to avoid sudden abnormal situation of the solar panel, and then the data is transmitted to the monitoring equipment through the line, but due to the limited length of the line, if the distance between the solar panel and the monitoring equipment is too far, It will be difficult to set up the circuit. In addition, because the circuit may be damaged under long-term use, this is also a disadvantage. Therefore, how to reduce the loss of the solar panel is a technical issue that needs to be solved urgently.

Since the solar panel in the prior art is under the sunshine, the quality problem will cause the temperature to rise and cause burnout, and even the whole photovoltaic power station is destroyed and scrapped. In view of the aforementioned shortcomings of the prior art, the present invention discloses a solar panel wireless power sensor. A measuring device and a monitoring system, the purpose of which is to monitor the solar panel to reduce losses. The wireless power sensing device can track the function of the solar panel. The sensing device includes a power unit, a central processing unit and a detection unit. The power unit is The external electric field, magnetic field and other high-frequency signals are converted into working power to provide the sensing device to work, and the central processing unit is used to control the detection unit, and use the detection unit to monitor the working temperature of the solar panel and display it; With a large number of panels, wireless power sensing devices can form a monitoring system. The arrangement and configuration of solar panels can monitor the entire system and troubleshoot, thereby reducing losses.
