Embodiment 1

[0039] refer to Figure 1 to Figure 8 , shows a schematic diagram of a detection system applied to photovoltaic module fault detection provided by Embodiment 1 of the present application, and the detection system is set on an automatic cleaning device of a photovoltaic module. The automatic cleaning device is used to move along with the photovoltaic panels to be cleaned, and to clean the photovoltaic panels during the movement. During the cleaning process, the detection system simultaneously detects the temperature of the photovoltaic panel to be cleaned.

[0040] Specifically, the detection system includes a first temperature detection unit. In this embodiment, the first temperature detection unit is a thermal infrared temperature probe 36, which detects the temperature of the photovoltaic panel when the automatic cleaning device cleans the photovoltaic panel. The detection system also includes an intelligent control unit 13 shared with the automatic cleaning device. As a par...

Embodiment 2

[0049] refer to Figure 9 to Figure 12 , shows a schematic diagram of the detection system applied in the fault detection of photovoltaic modules provided by Embodiment 2 of the present application. The main difference between Embodiment 2 and Embodiment 1 is that the automatic cleaning device where the detection system of Embodiment 2 is located The frame is segmented. Correspondingly, the thermal infrared temperature probes 36 are evenly distributed on the segmented frame. For the other same parts, refer to the above-mentioned embodiment 1, which will not be repeated here. It is specifically divided into two sections, or may be divided into more than two sections, which is not limited in this application. In this embodiment, the protective cover 10 and the brush 1 are also arranged in a two-stage segmented structure, which is described in detail as follows.

[0050] The frame includes two ends 6, 7 and a middle part, the middle part is segmented, and the protective cover 10...

Embodiment 3

[0053] This embodiment provides a detection system applied to photovoltaic module fault detection, specifically a thermal infrared detection system, which is integrated and installed in a photovoltaic module automatic cleaning device, such as Figure 13 to Figure 16As shown, the photovoltaic module automatic cleaning device includes an upper end box assembly 30, a middle section assembly 35, a lower end box assembly 33, a frame, a motor 12, a transmission assembly 31 and a cleaning assembly 32, and the upper end box assembly 30, the lower end box assembly 33 and the middle The segment assembly 35 is connected into a whole by the frame, and the cleaning assembly 32 is respectively installed between the upper end box assembly 30 and the middle section assembly 35, between the lower end box assembly 33 and the middle section assembly 35, and the upper end box assembly 30, the lower end The box assembly 33 and the middle section assembly 35 are respectively provided with driving wh...

Abstract

The invention discloses a detection system and a detection method for detecting the faults of a photovoltaic module. The system is arranged on an automatic cleaning device of the photovoltaic module. The automatic cleaning device is used for cleaning a to-be-cleaned photovoltaic panel while moving along the photovoltaic panel. The detection system comprises a first temperature detection unit, an intelligent control unit and a wireless communication unit. The first temperature detection unit is used for detecting the temperature of the photovoltaic panel during the cleaning process of the photovoltaic panel by the automatic cleaning device. The intelligent control unit is connected with the first temperature detection unit and is used for receiving and processing the detected temperature of the first temperature detection unit. The wireless communication unit is connected with the intelligent control unit and is used for sending the processed temperature of the intelligent control unit to a master control chamber. According to the invention, the photovoltaic panel is cleaned, while the temperature of the photovoltaic panel is detected at the same time. Meanwhile, the detected temperature is transmitted to the master control chamber. Therefore, once a photovoltaic panel generates electricity abnormally, the photovoltaic panel can be replaced just in time. As a result, the power generation efficiency of the photovoltaic module is greatly improved, and the service life of the photovoltaic module is greatly prolonged.

Description

[0001] This application takes the invention patent with the application number 201510202706.0, the application date as April 27, 2015, and the invention title as "A Thermal Infrared Detection System Applied to Photovoltaic Module Fault Detection" as the priority document. technical field [0002] The invention relates to the field of photovoltaic module cleaning and fault detection, in particular to a detection system and a detection method applied to photovoltaic module fault detection. Background technique [0003] At present, with the rapid development of the photovoltaic power generation industry, the photovoltaic power generation industry has become a new trend in the domestic and foreign power generation industry due to its advantages of environmental protection and high energy quality. However, since the photovoltaic panels used in photovoltaic power generation are usually installed outdoors, Outdoor dust, smog, rain, bird droppings, etc. will pollute and cover the sur...
