DETAILED DESCRIPTION

[0028] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0029] Reference Figure 1-8The embodiment of the present invention is a photovoltaic inverter detection and monitoring device, which includes: a photovoltaic inverter 1 and a monitoring mechanism 2. The lower surface of the photovoltaic inverter 1 is detachably connected with the monitoring mechanism 2. The monitoring mechanism 2 includes a box 201 and an adapter module 204. The upper surface of the box 201 is fixedly connected with a hanging top plate 203. The upper surface of the hanging top plate 203 is fixedly connected with the adapter module 204. The interior of the box 201 is provided with a touch unit 208. The inner wall of the box 201 is fixedly connected with a monitoring module 211, which is used for electrical signal collection and conversion and analysis of collected data, for stepping motor 2086 control and instruction execution, collection data status monitoring and fault diagnosis, and interaction with a remote communication module 209. The inner wall of the box 201 is fixedly connected with a remote communication module 209 to realize remote monitoring command transmission, and can receive various commands from terminals, such as computers in the monitoring center, smart phones, etc. These commands include but are not limited to controlling the movement of the stepper motor in the touch unit 208, controlling the attraction and release of the electromagnet 20815, retrieving monitoring data, and adjusting the parameter settings of the monitoring module 211, etc. It ensures that the monitoring mechanism 2 can respond to the control needs of the remote operator in a timely and accurate manner, and realize remote operation and management of the photovoltaic inverter 1.

[0030] The received remote command is accurately transmitted to the monitoring module 211, so that the monitoring module 211 performs the corresponding operation according to the command. For example, when the terminal sends a command to control the rotation of the stepper motor 2086, the remote communication module 209 quickly forwards the command to the monitoring module 211, and the monitoring module 211 then drives the stepper motor 2086 to rotate according to the command through the stepper motor control module 212, thereby realizing the precise movement of the movable seat 20810 and the precise contact between the contact 2089 and the metal contact 2081, so as to obtain the electrical signal data of a specific position.

[0031] The remote communication module 209 ensures the remote transmission of monitoring data and provides a channel for transmitting a large amount of data collected by the monitoring module 211 to the remote terminal. These data cover various operating parameters of the photovoltaic inverter 1, such as input and output voltage, current, and power. Through this module, data can be transmitted to the remote terminal in an efficient and stable manner, realizing real-time remote monitoring of the operating status of the photovoltaic inverter 1. During the data transmission process, the data may need to be format converted and preprocessed to adapt to the requirements of different network transmission protocols and remote terminal devices. For example, the raw data collected by the monitoring module 211 is converted into a data packet format suitable for transmission in a wireless network, such as 4G, 5G or Wi-Fi, to ensure the accuracy and integrity of the data during the transmission process, while improving the efficiency of data transmission and reducing the risk of transmission delays and data loss.

[0032] The remote communication module 209 ensures that the remote communication is stable and reliable, supports multiple communication protocols, such as TCP / IP, UDP, HTTP, etc., and can communicate with different types of remote terminal devices and monitoring systems. By adapting different communication protocols, the accurate transmission of data between different network environments and devices is guaranteed, and the seamless connection between the monitoring device and the remote monitoring platform is realized, which improves the versatility and scalability of the system.

[0033] The remote communication module 209 supports remote video transmission in combination with the video acquisition module 213. When used in conjunction with the video acquisition module 213, it provides a transmission path for the real-scene video information inside the monitoring mechanism 2 acquired by the video acquisition module 213. The real-time video data is continuously transmitted to the remote terminal, so that the operator can intuitively observe the working conditions inside the monitoring mechanism, including the equipment operation status, cable connection status, whether there is abnormal heating or smoking, etc., providing more abundant information basis for fault diagnosis and equipment maintenance.
