[0018] Figure 1 、 2As shown, before use, one or four sets of RJ45 sockets of the wired data receiving device and one or more RJ45 sockets P1 or P2, P3, P4 of the Ethernet controller module are respectively connected by RJ45 data connectors (both ends of the RJ45 data line have plugs). After the AC 220V power supply enters the power input end of the power module U, the power output end of the power module U outputs a stable DC 3.3V power supply to the power input end of the SD card seat module U1, the wireless receiving module U2, the Ethernet controller module U3, the Ethernet switch module U4, and the protection circuit. The above modules and circuits work. After other wireless devices send out wireless network data (the SD card seat module U1 can make the wireless receiving module U2 connect to the mobile wireless network to realize the reception of 4G or 5G data), the wireless network data signal is transmitted to the wireless network data module U2 after being protected by five ESD protection diodes D1, D2, D3, D4, and D5 (mainly to protect electronic components, circuits, and devices from electrostatic discharge (ESD)). After the wireless receiving module U2 receives the wireless network signal under the action of its internal circuit, the received 4G or 5G data wireless data signal is amplified, filtered, and demodulated, and is converted into a digital signal and transmitted to the Ethernet controller module U3. During transmission, capacitors C1 and C2 filter out the direct current component in the signal, making the signal symmetric about the 0 level (0 level symmetry means that the direct current component in the signal is filtered out, making the signal symmetric about the 0 level in the time domain. This processing helps to improve the quality and stability of the signal. Specifically, many high-speed signals will superimpose a direct current component on the signal to reduce attenuation. At the receiving end, the direct current component generally has its own bias, so it needs to be filtered out. At the same time, the capacitor can also filter out some direct current signals from the cross talk, thereby improving the signal quality), improving the quality of the data signal. Resistors R1, R2, R3, and R4 can absorb reflected signals and interference pulses (when the signal frequency is high, electronic signals will be reflected at places with different impedances (impedance discontinuities, such as the ends of transmission lines, corners, vias, component pins, line width changes, etc.). By connecting resistors R1, R2, R3, and R4 in series at the signal transmitting end, these phenomena can be effectively improved, making the signal more stable. Specifically, the impedance at the signal source end is usually low, with an internal resistance (the internal resistance is not a fixed value, but varies). Generally, it is less than 50 ohms, while the transmission line impedance is 50 ohms. The impedance inconsistency will cause signal reflection. Adding a resistor to the signal line can improve signal reflection, making the internal resistance plus the series resistance equal to or close to the impedance of the transmission line, thereby eliminating signal reflection.), diodes D6, D7, D8, D9, D10, and D11 protect the circuit from electrostatic discharge.Ethernet controller module U3 under the action of its internal circuit, the received wireless network signal decoding, error correction processing data packet transmission to the Ethernet switch module U4, Ethernet switch module U4 under the action of its internal circuit, data receiving, processing and forwarding data packet, the processed signal conversion to a wired network signal through one or more RJ45 Ethernet interface output (Ethernet switch module U4 multiple input and output data do not interfere with each other), so that the Ethernet switch module U4 will output corresponding one or more wired data signal to a set or four sets of wired data receiving equipment data input terminal, complete a set or four sets of wired data receiving equipment receiving wireless data signal flow equipment. Specifically, when the first or second, third, fourth RJ45 Ethernet interface output data of Ethernet switch module U4 to the corresponding one or four sets of wired data receiving equipment, its 86 or 82, 79, 77 pin will output high level to the anode power supply input terminal of LED1 or LED2, LED3, LED4, then the LED1 or LED2, LED3, LED4 will be powered on to light up the Ethernet switch module U4 of the first or second, third, fourth RJ45 Ethernet interface output data.
