Description
Technical Field

Background
HPLC is a high-speed power line carrier, also known as a broadband power line carrier, and is a broadband power line carrier technology for data transmission over low-voltage power lines. The broadband power line carrier communication network is a communication network which takes a power line as a communication medium and realizes the aggregation, transmission and interaction of the power utilization information of low-voltage power users. The broadband power line carrier mainly adopts an Orthogonal Frequency Division Multiplexing (OFDM) technology, and the frequency band uses 2MHz-12 MHz. Compared with the traditional low-speed narrowband power line carrier technology, the HPLC technology has large bandwidth and high transmission rate, and can meet the higher requirement of low-voltage power line carrier communication.
However, in the actual use of HPLC, due to the interference caused by equipment mismatch, environment and the like, a part of electric meters cannot communicate with the main node carrier communication equipment, and an island device is formed. The existing solution usually adopts a wireless communication method, but the wireless communication emits electromagnetic waves, and the electromagnetic waves generated by the power equipment itself when the power equipment is powered on can cause interference to communication signals, resulting in poor communication effect and easy error, so that improvement is needed. In addition, when the master node carrier communication device and the slave node carrier communication device are connected in a wired communication manner, a male plug and a female plug are generally adopted, and communication failure may be caused due to poor contact or the fact that a communication pin is bent due to carelessness in insertion.

The master node carrier communication device 1 corresponds to a plurality of slave node carrier communication devices 4. A light-tight chamber 6 is mounted within the electricity meter 5.
The using method of the invention is as follows:
the main node carrier communication equipment 1 and the slave node carrier communication equipment 4 convert the sent messages into data of 0 and 1, wherein 0 controls the LED not to emit light, namely to be turned off, and 1 controls the LED lamp to emit light, namely to be turned on; and then controlling the LED lamp to flash at a preset frequency to send a message.
