[0034] Main chip 110;

[0035] WIFI module 120, WIFI module 120 is connected to main chip 110;

[0036] The ZigBee / Bluetooth / Thread three-in-one module 130 is connected to the main chip 110, and the ZigBee / Bluetooth / Thread three-in-one module 130 is connected to the WIFI module 120 through the Packet Traffic Arbitration (PTA) interface.

[0037] Mobile communication module 140 is connected to main chip 110.

[0038] For example, the main chip 110 is a central processing unit that runs the Linux operating system. It can centrally process various types of data, such as Wi-Fi, ZigBee / Bluetooth / Thread, and mobile networks, enabling intelligent switching between multiple communication protocols and efficient data transfer, thus improving the overall system performance and response speed.

[0040] This utility model provides a multi-mode communication gateway, comprising a main chip, a WIFI module, a ZigBee / Bluetooth / Thread three-in-one module, and a mobile communication module. All three modules are connected to the main chip. The ZigBee / Bluetooth / Thread three-in-one module and the WIFI module are connected via a data packet traffic arbitration interface, achieving integrated support for multiple communication protocols. This overcomes the limitations of traditional single-protocol gateways with their limited functionality, meeting complex and varied communication needs. It can centrally process various types of data, including Wi-Fi, ZigBee / Bluetooth / Thread, and mobile networks, enabling intelligent switching between multiple communication protocols and efficient data transfer. This improves the overall system performance and response speed. The ZigBee / Bluetooth / Thread three-in-one module and the WIFI module are connected via a data packet traffic arbitration interface, dynamically adjusting communication priorities to ensure high-priority tasks are completed first, avoiding conflicts and improving communication reliability and stability.

[0041] In some embodiments of this utility model, the WIFI module 120 is a dual-band WIFI module of 2.4GHz and 5GHz, such as... Figure 1 As shown, the WIFI module includes a WIFI chip 121, a first filter 122, a duplexer 123, and a dual-band antenna 124.

[0042] The dual-band antenna 124 receives Wi-Fi electromagnetic wave signals to communicate with external Wi-Fi devices. The 2.4GHz or 5GHz Wi-Fi electromagnetic wave signals are combined or separated by a duplexer 123, filtered by a first filter 122 to remove signals outside the Wi-Fi band (such as 4G cellular network signals), demodulated by the Wi-Fi chip 121, and finally connected to the main chip 110 via a high-speed interface such as PCIe, SDIO, or USB to transmit Wi-Fi data for processing. Similarly, the data signals emitted by the main chip 110 are modulated into Wi-Fi signals by the Wi-Fi chip 121, filtered by a first filter 122 to remove signals outside the Wi-Fi band, combined or separated by the duplexer 123 for 2.4GHz or 5GHz signals, and then transmitted by the dual-band antenna 124.

The ZigBee, Bluetooth, or Thread electromagnetic wave signals are filtered by a second filter 132 to remove interference signals (such as mobile network signals). The ZigBee / Bluetooth / Thread integrated chip 131 demodulates the ZigBee / Bluetooth / Thread signals. Finally, the ZigBee / Bluetooth / Thread integrated chip 131 connects to the main chip 110 via a UART interface to transmit the demodulated signal to the main chip 110 for processing. Similarly, the data signals emitted by the main chip 110 are modulated into ZigBee, Bluetooth, or Thread electromagnetic wave signals by the ZigBee / Bluetooth / Thread integrated chip 131, filtered by the second filter 132 to remove interference signals, and then transmitted by the 2.4GHz antenna 133.

[0046] The mobile communication antenna 142 receives electromagnetic wave signals from the mobile network of external devices, which are amplified, filtered, and demodulated by the mobile communication chip 141 before being transmitted to the main chip 110 for processing. Similarly, the data signals emitted by the main chip 110 are amplified, filtered, and modulated by the mobile communication chip 141 before being transmitted by the mobile communication antenna 142.

[0047] In some embodiments of this utility model, such as Figure 1 As shown, the multi-mode communication gateway also includes a clock module 150, which includes a clock power supply 151 and a real-time clock chip 152. The real-time clock chip 152 is connected to the main chip 110 via an I2C interface, and the clock power supply 151 is connected to the real-time clock chip 152.

The clock power supply 151 is used to power the real-time clock chip 152; for example, the clock power supply 151 can be a button battery.

[0049] In some embodiments of this utility model, such as Figure 1 As shown, the multi-mode communication gateway also includes a flash memory 170, which is connected to the main chip 110 and is used to store the program and data of the main chip 110.

[0050] The main chip 110 is equipped with a network interface 180. For example, the network interface 180 can be a 100 Mbps network port or a gigabit network port, which is used to perform wired data interaction with external routers / optical modems / Ethernet, etc. via network cables.

[0051] In some embodiments of this utility model, the multi-mode communication gateway further includes a power supply module. Figure 2 A schematic diagram of the power module provided by this utility model is shown below. Figure 2 As shown, the power module includes a power adapter 191, a power detection circuit 192, a rechargeable battery 193 (e.g., a lithium battery), a battery management chip 194, a first DC-DC conversion circuit 195, a second DC-DC conversion circuit 196, and a third DC-DC conversion circuit 197.

[0052] Power adapter 191 connects to an external AC power source and converts the AC power input from the external AC power source into DC power. For example, power adapter 191 converts external 220V AC power into 12V DC power. A first DC-DC conversion circuit 195, a second DC-DC conversion circuit 196, and a third DC-DC conversion circuit 197 are all connected to power adapter 191. The first DC-DC conversion circuit 195 is connected to the main chip 110, the WIFI chip 121, the ZigBee / Bluetooth / Thread three-in-one chip 131, and the flash memory 164, respectively. The first DC-DC conversion circuit 195 converts the DC power output from power adapter 191 into DC power of a first voltage value (e.g., 3.3V) to power the main chip 110, the WIFI chip 121, the ZigBee / Bluetooth / Thread three-in-one chip 131, and the flash memory 164. The second DC-DC converter circuit 196 is connected to the mobile communication chip 141. The second DC-DC converter circuit 196 converts the DC power output from the power adapter 191 into a second voltage value (e.g., 3.8V) to power the mobile communication chip 141. The third DC-DC converter circuit 197 is connected to the voice chip 161 and the audio power amplifier 162. The third DC-DC converter circuit 197 converts the DC power output from the power adapter 191 into a third voltage value (e.g., 6.5V-8V) to power the voice chip 161 and the audio power amplifier 162.

[0053] The battery management chip 194 is connected to both the power adapter 191 and the rechargeable battery 193, enabling charge and discharge management of the rechargeable battery 193.

The first DC-DC conversion circuit 195, the second DC-DC conversion circuit 196, and the third DC-DC conversion circuit 197 are all connected to the rechargeable battery 193. The power detection circuit 192 detects the output voltage of the power adapter 191 and, when the power adapter 191 has no voltage output, sends a discharge enable signal to the battery management chip 194, causing the rechargeable battery 193 to discharge. The discharge then powers other components through the first DC-DC conversion circuit 195, the second DC-DC conversion circuit 196, and the third DC-DC conversion circuit 197. This invention uses a rechargeable battery as a backup power source, avoiding the limitations of traditional independent power adapters and providing convenience for emergency applications, portable use, and outdoor scenarios, thus expanding the product's application range.
