Technical Field
[0001] The utility model relates to a wireless gateway, and more specifically to an intelligent terminal fusion communication gateway device. Background Art
[0002] In the field of modern wireless communications, wireless gateways are key nodes for connecting different networks and transmitting data, and their stability and reliability are crucial. However, due to the different power supply voltages that can be provided in different application scenarios, traditional outdoor gateway devices are usually only suitable for a specific power supply voltage range, which greatly limits their application scope and flexibility. For example, some outdoor gateways may require a stable DC voltage supply, while the site may only provide AC or other non-standard voltages.
[0003] To solve this problem, one current solution is to connect a voltage converter in series to the power supply line of the wireless gateway. This approach is similar to the power adapter used in laptops, which can convert the input power voltage into the voltage required by the gateway. The use of this voltage converter has improved the adaptability of the wireless gateway to different power supply voltages to a certain extent, allowing the gateway to be used in more application scenarios. However, existing voltage converters can usually only convert certain voltage values, which means that they cannot cover all possible power supply voltage conditions. In addition, the addition of a voltage converter not only increases the size of the wireless gateway, but may also increase the complexity of installation and maintenance, while also increasing costs. These factors reduce the flexibility and portability of the wireless gateway, especially in scenarios where space is limited or rapid deployment is required.
[0004] Therefore, although the existing solutions can expand the voltage application range of wireless gateways to a certain extent, there are still many shortcomings. A more efficient, flexible and wide-range input voltage wireless gateway design is needed to meet the growing needs of diverse application scenarios. In addition, outdoor gateways are usually deployed in open environments such as urban streets, parks, and transportation hubs, which require high signal transmission capabilities and are inevitably exposed to various severe weather conditions, including rain, wind, sand, temperature changes, etc. Therefore, waterproof performance is a core consideration in the design of outdoor gateways.

[0026] The utility model embodiment discloses an intelligent terminal fusion communication gateway device, referring to Figure 1 The gateway has four LORA antennas 1 installed on the top, a power interface 3 and a network interface 2 at the bottom, and a voltage regulation circuit inside. The voltage regulation circuit includes a switching voltage regulator chip, and the power supply pin and the enable pin of the switching voltage regulator chip are connected to the power interface of the communication gateway; the switch pin is connected to the control mainboard to be powered in the communication gateway through an inductor, and after the switch pin is connected to the inductor, it is connected to the feedback pin of the switching voltage regulator chip through a voltage divider resistor network.
[0027] In one embodiment, referring to Figure 2 In this voltage regulation circuit, the switching regulator chip model is U3502. The U3502 chip is a high-performance step-down converter used to meet the power management needs of various electronic devices. Through high efficiency and compact packaging, this chip provides a reliable power solution that can adapt to different input voltages and has excellent output voltage regulation capabilities.
[0028] U3502 includes 8 pins, among which the 1st pin is the power supply pin, denoted as VIN, which is directly connected to the power interface of the communication gateway device; the 3rd pin is the enable pin, denoted as EN, which is connected to the power interface of the communication gateway device through the resistor R6; at the same time, in the present application, the power interface is directly grounded through the first capacitor CD1, and grounded through the first capacitor C1; preferably, in the present embodiment, the resistance value of R6 is 510K, the parameter of CD1 is 10uF / 100V, and C1 is 104 / 100V.
[0029] Furthermore, the 7th pin of the chip is used as a switch pin, denoted as SW, which is responsible for the high-voltage switch output and converts the input voltage into a set output voltage. In this embodiment, the SW terminal directly outputs the adjusted voltage to the control mainboard to be powered in the communication gateway device through the first inductor L1;
[0030] In order to accurately obtain the set output voltage, the feedback pin FB, that is, the 5th pin, is connected to a voltage-dividing resistor network. Specifically, the 5th pin is grounded through a resistor R2, and is connected to the output side of the first inductor L1 through a resistor R1, and a capacitor CFF is connected in parallel at both ends of the resistor R1. In this embodiment, the output voltage is adjusted by changing the value of the resistor in the voltage-dividing network. Preferably, the resistance value of the resistor R1 is 9.1K, and the resistance value of the resistor R2 is 1K. At this time, the output voltage is 12V1A.

[0037] Among them, the first antenna hole and the fourth antenna hole are installed with 3dBi LORA antennas; the second antenna hole and the third antenna hole are installed with 2dBi LORA antennas.
[0038] The LORA antenna focuses on long-distance communication and supports point-to-point communication. It can achieve low-power and long-distance communication. It also has strong signal penetration capability and a longer signal coverage range.
[0039] This application simultaneously sets up 4 antenna combinations, which can meet the needs of different communication distances and coverage ranges and improve the transmission quality of wireless signals.
[0040] Preferably, the 3dBi LORA antenna is HTQB400V3AM; the 2dBi LORA antenna is HTQB400V2AM.
[0041] In one embodiment, a power interface 3 and a network interface 2 are provided at the bottom; and a waterproof interface is installed on the power interface 3 and the network interface 2. The interface part of the outdoor gateway (such as the power interface, network interface, data interface, etc.) is the weak link of waterproofing. The present invention installs a waterproof interface with a protective cover for the above interface, which can effectively improve the waterproofing performance.
[0042] In another embodiment, a power switch 5 is further provided at the bottom.
