Photovoltaic Plant Lora Networking Solution is to collect the data of the inverter, combiner box, irradiator, meteorological instrument, energy meter and other equipment in the photovoltaic power station through RS232/RS485, and transmit it to the network server or local computer of the management center by Lora, then the operation and maintenance personnel can view the relevant Data and manage on the computer.
Through the combination of the LoRa wireless terminal and the LoRa gateway, the parameter information such as working state, current, voltage, and rated power of each panel of the photovoltaic array is transmitted to the management background via operator network for real-time monitoring and analysis;
1. Through the combination of the LoRa wireless terminal and the LoRa gateway, the parameter information such as working state, current, voltage, and rated power of each panel of the photovoltaic array is transmitted to the management background via operator network for real-time monitoring and analysis;
2. It can also monitor the status information of the PV array, temperature and humidity sensors and other parameters in the local control room. These data can be received by Lan port, WiFi and RS232/485 serial port;
3. Managers can monitor the key parameters of PV array through the APP at any time and anywhere with mobile phone.
１. High sensitivity of LoRa wireless terminal
Its receiving sensitivity is as high as -140dBm, and the link budget is 160dBm, leading in the industry, which can penetrate several walls and has strong diffraction ability.
２. Stable and reliable communication
The industrial-grade wireless terminal has built-in watchdog to ensure stable operation of the system for long time. The LoRa modulation and demodulation technology derived from military tactical communication system has strong anti-interference ability. The LoRa+ full Netcom gateway can do self-detection and automatic recovery to ensure permanent online.
３. High precision data
The terminal adopts efficient cyclic interleaving FEC forward error correction coding, maximum error correction 64bit, dual 256 ring FIFO, ensuring data high precision transmission.
４. Adjustable Power
The terminal can flexibly adjust power level to adapt to the distance and rate requirements during data transmission.
５. Strong environmental adaptability
High temperature resistant, designed for the harsh and unattended environment in the wild. With forward error correction technology, redundant information is added to the data sequence to be transmitted, and the error symbols injected in the data transmission process are corrected in time at the receiving end. Combined with the four-channel channel collision detection optimization technology, the problem of node data concurrent packet loss in actual engineering is solved, which greatly improves the link robustness.
