Wireless communication method and wireless terminal for photovoltaic power generation monitoring

Abstract

The present invention belongs to the communication technology field, and provides a wireless communication method for photovoltaic generation monitoring and a wireless terminal for photovoltaic generation monitoring. The method comprises: decrypting pre-receiving first linear frequency modulation and spread spectrum signals, obtaining decryption message, extracting user data from the decryption message, determining a target serial port address, assembling the user data to the serial port message according to the pre-obtained serial port protocol format, transmitting the serial port message to a target serial port address, and verifying the monitoring data fed back by the target serial port address, if the verification is successful, packing the monitoring data and the identity identification to data message according to the pre-obtained communication protocol, performing encryption of the data message to form encryption message, and converting the encryption message to second linear frequency modulation and spread spectrum signals for transmission. The wireless communication method for photovoltaic generation monitoring and the wireless terminal for photovoltaic generation monitoring can improve the information transmission efficiency, ensure the transmission distance, avoid damaging of a communication cable and reduce the communication interference and cost.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a wireless communication method and a wireless terminal for photovoltaic power generation monitoring. Background technique [0002] At present, in order to reduce line loss in the photovoltaic power generation site, a 10-35KV box-type booster station is usually installed next to the photovoltaic inverter. They are all in the open wilderness, and the natural environment is relatively harsh. Managers usually use the scheme of "combiner box + communication management machine + management platform" to carry out "remote signaling, telemetry, remote control, and remote adjustment" on the photovoltaic box side. However, there are many disadvantages in the prior art: in the prior art, RS485 is mostly used for communication, and the communication distance has certain limitations, up to 1000 meters. RS485 communication rate is low, generally 9600bps ~ 19200bps. At the same time, ...

Problems solved by technology

During the data transmission of the operator's network 2G / 3G / 4G, although the interference is small and the data transmission is stable and reliable, the operating cost is high, and the operator needs to pay the traffic fee, and the data is transmitted through the operator's public network, so the data security is not high
