In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a schematic structural diagram of a wireless WiFi device for power line carrier communication according to an embodiment of the present invention. As shown in fig. 1, the power line carrier communication wireless WiFi device 100 includes: the signal separation module 110, the WiFi transmission module 120, the communication module 130, the signal amplification module 140, and the network transmission module 150.
The signal separation module 110 is configured to separate a network data carrier loaded on the ac power network and convert the network data carrier into a network signal. Specifically, the signal separation module 110 includes a voltage conversion unit 111, a signal acquisition unit 112, and a signal conversion unit 113, where the voltage conversion unit 111 is configured to convert an ac carrier into a low-voltage carrier that can be acquired by the signal acquisition unit 112; a signal collecting unit 112, configured to collect the network signal in the low-voltage carrier converted by the voltage converting unit 111; and a signal conversion unit 113, configured to convert the network signal acquired by the signal acquisition unit 112 into a network signal that can be recognized by the mobile terminal.
The WiFi transmitting module 120 receives the network signal converted by the signal separating module 110 and wirelessly transmits the network signal to a mobile terminal or other network devices.
The communication module 130 is configured to perform communication authentication with other WiFi devices based on a power line (i.e., wireless WiFi devices based on power line carrier communication), and send a wake-up instruction to the signal amplification module 140 after the authentication is successful. The communication module 130 includes an identity authentication unit 131 and a processing unit 132, where the identity authentication unit 131 authenticates the identity of the device 2 after receiving request information sent by another WiFi device (hereinafter, referred to as device 2 for convenience of description), so as to determine whether the device 2 is an authenticated device, and if so, sends the request information to the processing unit 132. The processing unit 132 further analyzes the request information to determine whether the network signal strength of the power interface connected to the device 2 is above a threshold value, and if so, enters a low power consumption mode and sends confirmation communication information to the device 2 at a fixed time interval to monitor the network signal strength of the power interface connected to the device 2 in real time; if not, the normal working mode is entered, and a wake-up instruction is sent to the signal amplification module 140.
The signal amplifying module 140 amplifies the strength of the network signal converted by the signal separating module 110 according to the wake-up instruction sent by the communication module 130, and sends the amplified network signal to the network transmitting module 150. It should be noted that the default state of the signal amplification module 140 is a sleep state, and before the wake-up command is not received, the signal amplification module is in the sleep state, so as to reduce the power consumption of the device and the generation of heat to the maximum extent.
The network transmission module 150 is used for loading the network signal sent by the signal amplification module 140 into a power line (i.e., an ac power grid) so that the network is distributed to each power interface. It should be noted that the default state of the network transmitting module 150 is a sleep mode, and it is in the sleep state before the signal sent by the signal amplifying module 140 is not received, so as to reduce the power consumption of the device and the generation of heat to the maximum extent.
It should be noted that the other WiFi devices mentioned in this embodiment may be the same WiFi device as the power line carrier communication wireless WiFi device 100, or may be different WiFi devices from the power line carrier communication wireless WiFi device 100. In the preferred embodiment, the other WiFi devices are the same WiFi devices as the power line carrier communication wireless WiFi device 100. And the distance between the other WiFi devices and the wireless WiFi device 100 for power line carrier communication is not greater than 100m, in the preferred embodiment, the distance is less than 50m, so as to ensure that the network signal loaded into the ac power grid by the network transmitting module 150 is attenuated and can still meet the requirements of the other WiFi devices.
Fig. 2 is a schematic diagram of a power line network for communicating a wireless WiFi device using a power line carrier according to an embodiment of the present invention. The power line network 20 comprises 3 power line carrier communication wireless WiFi devices 100, 200, 300.
After the communication module 130 of the plc WiFi device 100 receives the request information sent by the plc WiFi device 200, authenticate the identity of the plc WiFi device 200 to determine whether the plc WiFi device 200 is an authenticated device, after authentication, the processing unit 132 further analyzes the request information to determine whether the network signal strength of the power interface connected to the plc WiFi device 200 is above a threshold value, if so, enter a low power consumption mode, and send confirmation communication information to the plc WiFi device 200 at a fixed time interval to monitor the network signal strength of the power interface connected to the plc WiFi device 200 in real time, and once the network signal strength of the power interface connected to the plc WiFi device 200 is below the threshold value, the signal amplification module 140 sends a wake-up instruction, after receiving the wake-up instruction, the signal amplification module 140 amplifies the strength of the network signal converted by the signal separation module 110, and loads the amplified network signal into the power line through the network transmission module 150, and the signal separation module of the power line carrier communication wireless WiFi device 200 separates the network data carrier loaded on the ac power network and converts the network data carrier into the network signal.

The communication module 130 is used for communicating with other WiFi devices, and on the premise of confirming the identities of other WiFi devices, enhanced network signals can be provided for other WiFi devices through the signal amplification module 140 and the network transmission module 150. Because the power line carrier communication wireless WiFi device 100 is designed with high integration on each module, the device is small in size, can be inserted into a power socket of a power line anywhere, and is convenient to use.
In addition, because the power line carrier communication wireless WiFi device 100 has the functions of amplifying a network signal and transmitting the network signal, a plurality of power line carrier communication wireless WiFi devices 100 can be used in a matched manner, each power line carrier communication wireless WiFi device 100 can be used as a WiFi transmitting device or a network signal relay device, not only is the problem of a WiFi signal coverage blind area solved, but also the problem that WiFi is limited by distance is solved, meanwhile, because of the dormancy mechanisms of the signal amplification module 140 and the network transmitting module 150, power consumption is greatly reduced, and the problem of device heat dissipation is solved.
