Embodiment Construction
[0045] Photovoltaic intelligent monitoring method of the present invention, such as figure 1 As shown, it is mainly realized by four parts: photovoltaic power generation device 1 , intelligent control device 2 , operation monitoring device 3 and client terminal 4 .
[0046] The photovoltaic power generation device 1 can adopt various existing miniature photovoltaic power generation devices, and is installed on the same lighting surface as the solar heat collector 5, and provides voltage and current information and part of the electric energy required for operation to the intelligent control device 2.
[0047] The intelligent control device 2 can add an Internet of Things module on the basis of the existing single-chip microcomputer, connect with the operation monitoring device 3 through a signal line, and bidirectionally interconnect with the client 4 through the Internet of Things module. The intelligent control device 2 and the operation monitoring device 3 can be installed ...

The invention provides a photovoltaic intelligent monitoring method of a solar water heater. The method comprises the following steps of (1) installing a photovoltaic cell assembly of a photovoltaic power generation device on the same lighting surface of a solar heat collector, and determining the solar irradiation condition at the moment t; (2) setting the heat use demand and whether to assist electrical heating by a user; (3) reporting the operating condition and the fault information of the solar water heater to the user by monitoring the water temperature in a heat collecting water tank; and (4) if the water consumption time set by the user is reached, but the temperature of hot water in the heat collecting water tank cannot meet the temperature of hot water set by the user, starting an electric heater, reporting the power consumption to the user, and meanwhile, monitoring whether the current and voltage numerical values in the heating process have an abnormality, and reminding theuser of checking the electric heater when the abnormality occurs. According to the method, real-time monitoring of the performance of the solar water heater is realized, so that the use condition summary analysis of the solar water heater in the regional range is facilitated, and meanwhile, the after-sale service timeliness rate of a solar water heater manufacturer for the in-service water heateris improved.
Description
technical field [0001] The invention relates to a method for monitoring the running state of a solar water heater, belonging to the technical field of solar water heaters. Background technique [0002] With the popularization of solar thermal utilization technology and the need for energy saving and emission reduction, solar thermal utilization of high-rise buildings is becoming more and more extensive. However, due to reasons such as shading, improper installation or weather conditions, many solar water heaters do not heat up, which cannot meet the requirements and experience of consumers. [0003] Due to many influencing factors, it is difficult to find out the cause of the lack of heat after many high-rise solar water heaters are not hot, and the rate of customer complaints has increased sharply. Because they do not understand the specific situation of energy saving and power consumption of solar water heaters, many consumers dare not keep the solar water heaters powered...
