Embodiment 1

[0044] Such as figure 1 As shown, a photovoltaic panel fault location system based on a switch matrix, including a photovoltaic panel power generation matrix group connected in sequence, a data acquisition module, a central processing unit and an alarm display module;

[0045] in,

[0046] The photovoltaic panel power generation matrix group includes a plurality of photovoltaic panels electrically connected in sequence, and a normally closed switch D is arranged between any two adjacent photovoltaic panels;

[0047] The central processing unit is also signal-connected with a switch matrix module;

[0048] The switch matrix module includes a detection switch circuit and a PLC controller;

[0049] The detection switch circuit includes a plurality of normally open switches T arranged in sequence, and the number of the plurality of normally open switches T is the same as that of the photovoltaic panels; each normally open switch T is also electrically connected to a normally ope...

Embodiment 2

[0059] On the basis of Embodiment 1, this embodiment optimizes the data acquisition module, specifically: the data acquisition module includes a sensor module and a data transmission module, and the sensor module includes a voltage detection transformer, a temperature sensor, and a temperature sensor that are all connected to the signal of the data transmission module. sensor, humidity sensor and light intensity sensor.

[0060] The voltage detection transformer, temperature sensor, humidity sensor and light intensity sensor of this embodiment can respectively check the working voltage of the photovoltaic panel, the external temperature and humidity and the light intensity, so as to comprehensively judge the working condition of the photovoltaic panel from several aspects of data , so that it can be judged whether it is working normally, so that faulty photovoltaic panels can be screened out.

[0061] Based on the above, the data transmission module includes a transmission lin...

Embodiment 3

[0064] In this embodiment, on the basis of embodiment 1 or embodiment 2, the following structure is optimized: the number of the normally closed switch D, the normally open switch T, the normally open switch S and the number of photovoltaic panels are the same.

[0065] In this embodiment, each photovoltaic panel corresponds to a normally closed switch D, a normally open switch T, and a normally open switch S, so that during operation, it is only necessary to connect the photovoltaic panels that need to be detected, and disconnect the detected or undetected ones. Photovoltaic panels are enough, so that each detection can detect a photovoltaic panel independently, which has the effect of accurate detection and high positioning.

Abstract

The invention relates to a switch-matrix-based photovoltaic panel fault location system comprising a photovoltaic panel generation matrix group, a data acquisition module, a central processing unit and an alarm display module that are connected in sequence. The photovoltaic panel generation matrix group includes a plurality of photovoltaic panels connected successively and electrically; and a normally-closed switch D is arranged between any two adjacent photovoltaic panels. A switch matrix module is also in signal connection with the central processing unit and consists of a detection switch circuit and a PLC controller. In addition, the invention also discloses a switch-matrix-based photovoltaic panel fault location method. The system having a simple structure is operated conveniently andis capable of detecting a photovoltaic panel rapidly and precisely; all photovoltaic panels can be detected completely with high precision; a fault situation like puncture or failure of the photovoltaic panel as well as the aging situation of the photovoltaic panel can be detected during the detection process.

Description

technical field [0001] The invention relates to the technical field of photovoltaic panels, and more specifically relates to a photovoltaic panel fault location system based on a switch matrix. At the same time, the invention also discloses a photovoltaic panel fault location method based on the photovoltaic panel fault location system. Background technique [0002] Under the situation of energy crisis, solar photovoltaic power generation has been widely developed and applied as a renewable clean energy. Affected by the external environment and its own service life, solar photovoltaic panels usually have failures such as fragmentation and aging. The failure of solar panels will affect the efficiency of the entire power generation system, and in severe cases, fires will occur. [0003] At present, there are mainly fault diagnosis methods based on infrared images and electrical measurement fault diagnosis methods for equipment fault detection of solar photovoltaic power gener...
