4G Router Photovoltaic Power Generation Monitoring System

Posted by E-Lins Technology on November 21st, 2022

The solar photovoltaic power generation system is composed of a grid-connected inverter of photovoltaic cells, which directly inputs the electric energy into the public grid through the grid-connected inverter without energy storage by the battery. In sunny and remote areas, solar power systems are gradually replacing some traditional power equipment and become the first choice for power supply systems. However, as large-scale Taineng power stations are successively built and put into operation in China, how to understand the operation status of the power station in real time and how to meet the monitoring requirements of the upper-level system or the power grid dispatching system have become the problems that must be solved in the photovoltaic power station project.

The wireless remote monitoring system conducts real-time monitoring and control of on-site photovoltaic power stations, and realizes remote online monitoring of photovoltaic power stations, daily power generation statistics, site working status confirmation and control of its efficient and energy-saving operation. The system topology is as follows:

The system is mainly divided into three parts: data acquisition, data transmission, and data center. The data acquisition and data transmission equipment is deployed on the photovoltaic power generation site, and the data center is deployed on the cloud server.

The data transmission part is the core part of the whole system and is the hub for the communication between the photovoltaic power generation site and the cloud server. The industrial 4g router with ethernet supports Passive POE power reception, the camera can be connected to the device through the network port, and other terminal devices can be connected through the network port or serial port. The access router, the industrial router aggregates the data and sends the data to the cloud server through the VPN. The VPN is a two-way channel, and the server can also perform remote maintenance on the equipment while receiving the data.

The main functions of the system:

The cloud server monitors the scene condition through the camera in real time.

On the cloud server, the operation status of photovoltaic power generation can be viewed in real time.

Remote access to the router, and can configure the router and the devices under the router.

The server accepts and parses the data returned by the power station, detects the status and alarm information of the power station at all times, and handles problems in a timely manner.

Solution Advantages

Intelligent management, cost saving:

The monitoring data is forwarded without omission, reducing the cost of error correction and saving labor costs; visual monitoring, rapid response: configuration display, you can remotely view the on-site status at any time, and deal with problems in time;

7X24 hours operation: The industrial router has built-in hardware watchdog and various software reliability strategies to keep the network transmission uninterrupted.

Wide temperature and wide voltage design: The industrial router supports default 5-40V voltage input and can run stably at -40℃~75℃.

Support remote maintenance: The industrial router can be connected to the cloud assistant through an encrypted tunnel, and customers can maintain the industrial router and manage data acquisition equipment and cameras anytime and anywhere.

The cloud assistant can accommodate thousands of devices, which is convenient for future project expansion.
