System for transmitting electricity data through HPLC+HRF dual-mode communicationTechnical Field
The invention relates to the technical field of data transmission, in particular to a system for transmitting electricity data by HPLC+HRF dual-mode communication.
Background
In order to realize remote transmission of electricity consumption data in an electric power system, data such as electric quantity, voltage, total electricity consumption, power failure or the like in an electricity consumption area are generally uploaded in a wireless or wired mode. It is currently more advanced to transmit data by HPLC or HRF mode. The HPLC is a short for high-speed power line carrier, is a communication mode using the power line as a data transmission medium, and has great convenience in using the power line to transmit data information, and can form a communication network by all electric appliances connected with the power line without rewiring, so that information interaction and communication are performed, complex engineering is omitted, resource cost is saved, meanwhile, the firm structure of the power grid can be ensured, compared with the narrow-band carrier technology, the communication rate of the HPLC is improved from a few Kbps to hundreds Kbps or even a few Mbps, the communication reliability and stability are obviously improved, the requirements of electricity information acquisition are greatly met, and a complete and reliable carrier communication solution is provided for an electric power department and other public utility departments. The HRF is a mode of communication by using a high-frequency radio technology, the basic principle of the HRF communication is that high-frequency electromagnetic waves are utilized for signal transmission, signals are modulated and transmitted through an antenna, the antenna of a receiving end demodulates the received signals to restore the original signals, the basic HRF communication structure comprises a transmitting end and a receiving end, the transmitting end modulates the original signals and then transmits the original signals through the antenna, the signals are received by the antenna of the receiving end and then demodulated to obtain the original signals, and the HRF communication is more convenient because no line is needed for transmitting and receiving data, and has the characteristics of high efficiency, stability and rapidness, so the HRF communication is widely applied to the field of wireless communication and is more widely applied in recent years.
While the existing HPLC or HRF mode data transfer each have the described advantages, there are also specific technical drawbacks subject to the limitations of its own technology. Specifically, since the data is transmitted by adopting the power line in the HPLC mode, the distance of the data transmission is shorter and is generally not more than a few kilometers due to the characteristics of the power line; secondly, the power line has certain noise and interference, which can cause certain influence on the transmission of communication signals, and in addition, as the application range of the power line communication technology is wider, compatibility problems can exist among devices of different factories, which can also cause certain influence on the stability of communication; finally, when the power line is broken due to open circuit or the like, data cannot be transmitted to the terminal, and the factors have adverse effects on the application of the HPLC. The HRF mode data transmission device is a wireless mode for receiving and transmitting related data, when the transmitting data area is affected by the surrounding environment (such as in deep mountain), there are problems that the wireless signal is attenuated and the remote receiving end cannot effectively receive the data, so that the application of the HRF mode data transmission device is more or less adversely affected.
