Problems solved by technology

When the sending power of the concentrator is reduced, the sensitivity of the concentrator will decrease, and the transmission distance of the concentrator will also be shortened, thus reducing the success rate of communication between the concentrator and the far meter, so it often occurs that the concentrator sends too much Secondary signal, and the meter only receives one signal, so the efficiency of the concentrator to send the signal is also reduced

Embodiment 1

[0064] See figure 2 as shown, figure 2 The shown is a flowchart of a transmission method based on power line communication provided by the embodiment of the present invention. The method provided by this embodiment can be applied to an electronic device, and the electronic device can be a concentrator or other equipment. The method provided by the present invention The method can improve the success rate of communication between the electronic device and the terminal on the transmission power line, thereby improving the efficiency of the electronic device to send signals. The method includes:

[0065] Step S101, receiving an instruction for acquiring a signal or receiving an instruction for sending a signal;

[0066] Step S102, when the electronic device receives an instruction to acquire a signal, send an open signal to the sending switch on the sending power line to disconnect the sending power line, and send a closing signal to the receiving switch on the receiving powe...

Embodiment 2

[0091] See image 3 as shown, image 3 The flow chart shown is another transmission method based on power line communication provided by the embodiment of the present invention. This embodiment is an extension on the basis of Embodiment 1. The method steps of this embodiment are repeated with Embodiment 1. For specific content, please refer to the content of Embodiment 1, which will not be repeated in this embodiment. The method provided by the invention can prevent excessive peak-to-peak voltage signals from entering the power line carrier chip, thereby preventing the occurrence of signal saturation, so as to ensure that the power line carrier chip will not be burned by excessive peak-to-peak voltage. The method includes:

[0092] Step S201, receiving an instruction for acquiring a signal or receiving an instruction for sending a signal;

[0093] Step S202, when the electronic device receives an instruction to acquire a signal, send an open signal to the sending switch on ...

Embodiment 3

[0103] See Figure 4 as shown, Figure 4 Shown is a block diagram of a concentrator 1 provided by an embodiment of the present invention. The concentrator 1 is respectively connected to three transmission power lines and three reception power lines, and each transmission power line is provided with a transmission device that controls the opening or closing of the transmission power line. A switch, each receiving power line is provided with a receiving switch for controlling the opening or closing of the receiving power line.

[0104] exist Figure 4 In the shown embodiment, the concentrator 1 is mainly used to send an open signal to the transmitting switch on the transmitting power line to disconnect the transmitting power line when receiving an instruction to acquire a signal, and to send a closing signal to the receiving switch on the receiving power line To close the receiving power line; when receiving the instruction to send a signal, send an open signal to the receivin...

Abstract

The embodiment of the present invention discloses a transmission method and device based on power line communication, including: receiving an instruction to acquire a signal or receiving an instruction to send a signal; when an electronic device receives an instruction to acquire a signal, send Open the signal to disconnect the sending power line, send a closing signal to the receiving switch on the receiving power line to close the receiving power line; when the electronic device receives the instruction to send the signal, send a disconnecting signal to the receiving switch on the receiving power line to disconnect the receiving The power line sends a close signal to the transmission switch on the transmission power line to close the transmission power line. By sending the closing signal and the disconnecting signal to the sending switch and the receiving switch, so that the sending power line and the receiving power line will not be connected to the electronic device at the same time, the transmission power of the electronic device and the transmission distance of the signal are guaranteed, and the connection between the electronic device and the sending power line is improved. The communication success rate of the terminal can be improved, and the efficiency of electronic equipment to send signals can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a signal transmission method and device based on power line carrier communication. Background technique [0002] At present, in order to grasp the real-time information of electricity consumption in each area, the substation usually uses a concentrator to connect to the meters in each area through the power line, and uses the power line carrier (PLC) communication technology to converge the signals of the meters to the concentrator of the substation . [0003] See figure 1 As shown, since the substation mainly uses three-phase electricity for power supply, the existing concentrator 0 uses three power line carrier chips 01, 02 and 03 to connect with the meter 2 on the three-phase power line respectively. The three power line carrier chips 01 , 02 and 03 can not only receive the signal of the electric meter 2 in real time, but also send the signal to the el...
