Description

Technical Field

[0001] This utility model relates to the field of Internet of Things (IoT) technology, and in particular to a multi-channel data transmission gateway. Background Technology

[0002] With the rapid development of Internet of Things (IoT) and wireless communication technologies, the demand for high-precision, real-time positioning and data transmission is increasing, especially in fields such as intelligent transportation, industrial automation, smart cities, and emergency rescue.

[0003] Currently, traditional single-channel positioning methods, such as relying solely on GPS or BeiDou satellite systems, provide relatively accurate location information in open outdoor areas, but perform poorly in complex scenarios such as urban canyons and indoor environments, making it difficult to meet the requirements for comprehensive coverage and accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-channel data transmission gateway in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-channel data transmission gateway includes a housing, a control module, a LoRa gateway module, a clock circuit, a communication module, a power module, and a storage module. The LoRa gateway module, clock circuit, communication module, power module, and storage module are electrically connected to the control module. The housing includes an upper housing and a lower housing. Flanges are fixedly connected to the openings of both the upper and lower housings. Rails that are detachably connected to the flanges on the lower housing are fixedly connected to both sides of the flanges on the upper housing. Several heat dissipation slots are provided on both sides of the upper and lower housings.

[0007] As a further description of the above technical solution:

[0008] The upper housing has fixed rails on both sides of the flange that slide with the flange on the lower housing.

[0009] As a further description of the above technical solution:

[0010] The flange bottom side of the lower housing is fixedly connected with several studs, and the rail is provided with a slot to accommodate the studs. The free end of the stud is connected to several nuts that abut against the rail by threaded engagement.

[0011] As a further description of the above technical solution:

[0012] A cooling fan is fixedly installed on the top of the upper housing.

[0013] As a further description of the above technical solution:

[0014] The inner walls on both sides of the upper and lower housings are provided with grooves that communicate with the heat dissipation slots, and filters are embedded in the grooves.

[0015] As a further description of the above technical solution:

[0016] The communication module includes a wireless communication module, a BeiDou receiver chip, a UWB transceiver, and a Bluetooth beacon module, which are electrically connected to the control module.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. The multi-channel data transmission gateway solution integrating BeiDou satellite positioning, UWB ultra-wideband positioning and Bluetooth beacon positioning functions in this utility model can not only integrate data from different positioning technologies to provide more accurate and stable positioning services, but also has powerful data processing capabilities and flexible remote transmission mechanisms, making it suitable for a variety of application scenarios.

[0019] 2. In this utility model, the combination of sliding rail and nut fixing makes the assembly and disassembly of the housing simple and quick, which is conducive to the maintenance and upgrading of the gateway. The fastening effect of the stud and nut can ensure a high bonding force between the upper and lower housings, which enhances the overall structural rigidity. At the same time, it allows for a certain degree of dimensional tolerance adjustment. Because the stud and the slot can compensate for manufacturing errors within a certain range, it ensures assembly accuracy.

[0020] 3. In this utility model, when the cooling fan is started, it will form a directional airflow path: external cold air is drawn into the device through the heat dissipation slot, filtered by the filter screen, and flows directly to the heat-generating element. After absorbing heat, it is discharged to the external environment through heat dissipation slots in other locations. Combining active heat dissipation (fan) and passive heat dissipation (heat dissipation slot) mechanisms, it adapts to the heat dissipation needs under different environmental conditions and load states.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 This utility model provides a technical solution: a multi-channel data transmission gateway, including a control module 11, a LoRa gateway module 12, a clock circuit 13, a wireless communication module 14 (such as Wi-Fi / 4G / 5G), a Beidou receiver chip 15 (such as a Beidou / GNSS receiver chip), a UWB transceiver 16 (such as a Decawave DW100), a Bluetooth beacon module 17 (such as Bluetooth Low Energy BLE), a power module 18, and a storage module 19, all of which are electrically connected to the control module 11.

[0029] The control module 11, acting as the core processor, coordinates the work of various modules, receiving data from the Beidou receiver chip 15, UWB transceiver 16, and Bluetooth beacon module 17, and synchronizing the data using the precise timestamps provided by the clock circuit 13. The control module 11 performs preliminary processing on this raw data, such as filtering noise and removing outliers. The LoRa gateway module 12 and wireless communication module 14 are responsible for uploading the processed data to a cloud server or other remote terminals. The LoRa gateway module 14 is particularly suitable for long-distance, low-power data transmission, applicable to wide-area coverage scenarios, while the wireless communication module 14 supports higher-speed data transmission, such as Wi-Fi and 4G / 5G. The clock circuit 13 provides a high-precision time base, ensuring that all collected data has accurate timestamps, which is crucial for applications requiring precise time synchronization, such as event-triggered mechanisms in the Internet of Things or multi-sensor data fusion. The Beidou receiver chip 15 receives data from the Beidou satellite system. The system receives GNSS signals and extracts location information (such as latitude, longitude, and altitude). This data is then transmitted to the control module 11 for further processing. The UWB transceiver 16 uses ultra-wideband technology for precise distance measurement or positioning. The UWB transceiver 16 periodically sends and receives signals, calculates the distance to other UWB devices, and sends this data to the control module 11. The Bluetooth beacon module 17 scans surrounding Bluetooth beacons and reads their RSSI values ​​or other relevant information. This data is also transmitted to the control module 11 for indoor positioning or proximity detection. The power module 18 supplies power to the entire device and may include battery management functions to enable long-term operation without external power. It can also dynamically adjust the power supply of each component according to the current operating status to achieve energy saving. The storage module 19 is used for temporary or long-term data storage. In some cases, when the network is unavailable or to save bandwidth, the control module 22 will first store the processed data in the local storage module.

[0030] This device integrates multiple positioning technologies and communication methods, enabling it to effectively collect data from different sources. Through intelligent processing and optimized transmission strategies, it meets the needs of various application scenarios. Its workflow covers the entire process from data acquisition, processing, storage to final transmission to the target receiving end.

[0031] Specifically, such as Figures 1-3As shown, the housing includes an upper housing 1 and a lower housing 2. Both the open ends of the upper housing 1 and the lower housing 2 are fixedly connected to flanges 3. The flanges 3 of the upper housing 1 are fixedly connected to two sides of a retaining rail 5 that slides with the flanges 3 of the lower housing 2. The upper housing 1 slides along the retaining rail 5 to mate with the lower housing 2. Several studs 9 are fixedly connected to the bottom side of the flanges 3 of the lower housing 2. The retaining rail 5 has a groove 501 for accommodating the studs 9. When the upper housing 1 is fully slid into place, the studs 9 fixed to the bottom side of the flanges 3 of the lower housing 2 will enter the groove 501 on the retaining rail 5. Several nuts 10 that abut against the retaining rail 5 are screwed to the free ends of the studs 9. After the studs 9 pass through the groove 501, the nuts 10 are screwed into their free ends. The nuts 10 are gradually tightened until they abut tightly against the retaining rail 5, thereby achieving a firm connection between the upper and lower housings. This design not only facilitates rapid assembly, but also provides good mechanical stability and a certain degree of sealing performance, helping to protect internal electronic components from external environmental influences (such as dust, moisture, etc.).

[0032] Specifically, such as Figure 2 and Figure 4 As shown, a cooling fan 6 is fixedly installed on the top of the upper housing 1 to force airflow and accelerate the dissipation of heat inside the gateway. Several heat dissipation slots 4 are provided on both sides of the upper housing 1 and the lower housing 2. The heat dissipation slots 4 provide channels for natural convection, allowing heated air to be discharged from the inside of the gateway, while allowing cold air from the outside to enter. Even when the fan is not working, a certain degree of airflow can be maintained, thereby playing a role in auxiliary heat dissipation, maximizing heat dissipation efficiency, avoiding the formation of hot spots, and ensuring that all components can operate within a safe operating temperature range. Grooves 8 that communicate with the heat dissipation slots 4 are provided on the inner walls of both sides of the upper housing 1 and the lower housing 2. Filters 7 are embedded in the grooves 8 to prevent dust and other small particles from entering the inside of the gateway with the air and causing damage.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
