[0022] The implementation of this utility model will be described in detail below with reference to specific embodiments.
[0023] Reference Figure 1 The diagram shows a preferred embodiment of the present invention.
[0024] This utility model provides a communication networking system 100, including: a first controller 11, multiple communication lights 12 and a mobile communication terminal 13.
[0025] The first controller is used to connect to the switch 200. Communication lamp 13 is connected to the first controller 11 via power line 300, and communication lamp 12 communicates with the first controller 11 via power line 300. A communication area is constructed through multiple communication lamps 12. When the mobile communication terminal 13 enters the communication area, the mobile communication terminal 13 establishes a communication connection with the communication lamp 12 via an optical link.
[0026] Both the first controller and the second controller are power line communication (PLC) controllers.
[0027] The first controller 11 connects to the switch 200, loading the network signal from the switch 200 onto the power line 300. The power line 300 connects to multiple communication lights 12, converting the power signal into a network signal. The communication lights 12 then convert the network signal into a visible light signal, which is transmitted to the mobile communication terminal 13. Multiple mobile communication terminals 13 can move to any communication area covered by a communication light 12 to receive the visible light signal, enabling LiFi communication, high-speed internet access, real-time audio / video transmission, and remote control of the mobile communication terminals 13 for operations. The communication lights 12 and mobile communication terminals 13 not only support one-to-one connections but also one-to-many, many-to-one, and many-to-many bidirectional LiFi communication networks, allowing for highly customized networking to meet customer communication scenario needs.
[0028] This utility model provides a communication networking system, including: a first controller, multiple communication lights, and a mobile communication terminal. The first controller is used to connect to a switch; the communication lights are connected to the first controller via power lines and communicate with the first controller via the power lines. A communication area is constructed through multiple communication lights. When a mobile communication terminal enters the communication area, the mobile communication terminal establishes a communication connection with the communication lights via an optical link. The above-mentioned communication networking system has the following advantages: 1. Network deployment is simple by using existing power lines; 2. It can be reused as lighting equipment, eliminating the need to add multiple switches or routers; 3. Bandwidth is shared only by mobile communication terminals within the communication area; 4. It is not affected by electromagnetic radiation interference; 5. The confidentiality of information is ensured through optical communication.
[0029] It should be noted that, for ease of explanation, in Figure 2 In the schematic block diagram shown, the same unit in different systems or the same circuit in different systems share the same label, such as control chip 123, signal receiving unit 124 and signal transmitting unit 125.
[0030] In some embodiments, such as Figure 2 As shown, the communication lamp 12 includes: an AC unit 121, a second controller 122, a control chip 123, a signal receiving unit 124, and a signal transmitting unit 125. The first end of the AC unit 121 is used to connect to the power line 300. The first end of the second controller 122 is connected to the second end of the AC unit 121, and the second end of the second controller 122 is connected to the control chip 123. The control chip 123 is also connected to the first end of the signal receiving unit 124 and the first end of the signal transmitting unit 125, respectively.
[0031] The AC unit 121 draws power from the L / N lines of the power line 300. The second controller 122, acting as an internal PLC module, converts the signals on the power line 300 into network signals for communication with the control chip 123. The control chip 123 is a System-on-Chip (SOC) responsible for signal modulation and demodulation.
[0032] In some embodiments, such as Figure 2 As shown, the signal receiving unit 124 includes: an ADC circuit 1241, a secondary signal amplifier circuit 1242, a primary signal amplifier circuit 1243, and a photodiode 1244. The first terminal of the ADC circuit 1241 is connected to the control chip 123; the second terminal of the ADC circuit 1241 is connected to the first terminal of the secondary signal amplifier circuit 1242; the second terminal of the secondary signal amplifier circuit 1242 is connected to the first terminal of the primary signal amplifier circuit 1243; and the second terminal of the primary signal amplifier circuit 1243 is connected to the photodiode 1244.
[0033] When in operation, after the photodiode 1244 receives the visible light signal, the signal is amplified by the first-stage signal amplifier circuit 1243 and the second-stage signal amplifier circuit 1242 in sequence, and then converted into a digital signal by the ADC circuit 1241 and transmitted to the control chip 123. The control chip 123 then performs demodulation processing on the signal using its internal algorithm.
[0034] In some embodiments, such as Figure 2 As shown, the signal transmitting unit 125 includes: a DAC circuit 1251, a first-stage signal amplifier circuit 1243, a second-stage signal amplifier circuit 1242, and an LED. The first terminal of the DAC circuit 1251 is connected to the control chip 123, the second terminal of the DAC circuit 1251 is connected to the first terminal of the first-stage signal amplifier circuit 1243, the second terminal of the first-stage signal amplifier circuit 1243 is connected to the first terminal of the second-stage signal amplifier circuit 1242, and the second terminal of the second-stage signal amplifier circuit 1242 is connected to the LED.
[0035] During operation, the control chip 123 converts the digital signal into an analog signal through the DAC circuit 1251, and then amplifies it through the first-stage signal amplifier circuit 1243 and the second-stage signal amplifier circuit 1242 in sequence, before loading it onto the lighting LED to transmit the visible light signal.
[0036] In some embodiments, such as Figure 2As shown, the mobile communication terminal 13 includes: a signal receiving unit 124, a signal transmitting unit 125, a control chip 123, a first interface 131, a conversion unit 132, a second interface 133, and a power supply unit 134. The first ends of the signal receiving unit 124 and the signal transmitting unit 125 are both connected to the first end of the control chip 123. The control chip 123 is also connected to the first interface 131 and the first end of the conversion unit 132, respectively. The second end of the conversion unit 132 is connected to the second interface 133 and the power supply unit 134, respectively.
[0037] Among them, the control chip 123, as a SOC chip, is responsible for signal modulation and demodulation. The modulation and demodulation principle is the same as that of the communication lamp 12. It converts the processed signal into a network signal output through an internal algorithm. The first interface 131 is an RJ45 interface, the second interface 133 is a Type-C interface, and the conversion unit 132 is used for signal conversion processing. The Type-C interface can power the whole machine through the power supply unit 134, and can also transmit network signals. When using the Type-C interface to transmit network signals, there is no need to connect an RJ45 network cable, thus supporting both RJ45 and Type-C interface types of the device terminal.
[0038] It should be noted that the internal structures of the signal receiving unit 124 and the signal transmitting unit 125 are the same in the mobile communication terminal 13 and the communication lamp 12.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
