Description

Technical Field

[0001] This invention belongs to the field of satellite positioning technology, and in particular relates to a beacon system based on 4G network satellite positioning. Background Technology

[0002] Satellite positioning technology, as the name suggests, uses satellites for positioning. It has evolved from its initial stages of low positioning accuracy, inability to provide real-time positioning, and difficulty in offering timely navigation services, to today's high-precision GPS global positioning system. Satellite positioning can be used to guide aircraft, ships, vehicles, and individuals safely and accurately along selected routes to their destinations on time. Satellite positioning can also be applied to functions such as mobile phone tracking. A beacon system is indispensable for satellite positioning.

[0003] Chinese patent disclosure (CN1) (1356791OA) A wireless beacon positioning system and its positioning method belong to the fields of personnel positioning, Internet of Things, and wireless communication technology. The wireless beacon and transmission substation are paired and grouped on demand. Through on-demand configuration of transmission field strength and attenuation coefficient, signal strength threshold filtering, and other technologies, a positioning accuracy of the identification card is ensured by setting a signal strength threshold for the identification card's handshake signal, guaranteeing that the identification card can only communicate with the nearest wireless beacon or other devices. This can be limited by signal strength. By setting a signal strength threshold for sensing the identification card, the wireless beacon can automatically sense the presence of the identification card, enabling communication when a person arrives and sleep when they leave. This parameter limits the sensing range of the identification card and can also serve as a logic switch to enable or disable the sensing of the identification card. This satisfies the flexible requirements for on-demand deployment of positioning accuracy in petrochemical, chemical, and other work sites, while achieving low-cost, high-precision positioning results. Current positioning beacon systems do not have personalized design for the radio frequency spectrum, making them susceptible to interference from 2.4G WIFI signals during application. Furthermore, the beacon equipment lacks optimized power-saving modes and cannot achieve ultra-long standby time, requiring certain improvements. Summary of the Invention

[0004] The purpose of this invention is to address the problems of current positioning beacon systems, which do not have personalized design for the radio frequency spectrum, making them susceptible to interference from 2.4G WIFI signals during application, and the lack of optimized power-saving mode for beacon devices, thus failing to achieve ultra-long standby time. Therefore, this invention proposes a beacon system based on 4G network satellite positioning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a beacon system based on 4G network satellite positioning, comprising a GPS positioning module and a signal backhaul module, wherein the output end of the GPS positioning module is connected to the input end of the signal backhaul module, the output end of the signal backhaul module is connected to the input end of a smart gateway, and the output end of the smart gateway is connected to the input end of a beacon establishment module.

[0006] As a further description of the above technical solution:

[0007] The output of the beacon establishment module is connected to the input of the precise positioning module, the output of the precise positioning module is connected to the input of the result feedback module, and the output of the result feedback module is connected to the input of the receiving terminal.

[0010] As a further description of the above technical solution:

[0011] The smart gateway includes a Bluetooth Low Energy (BLE) unit and a satellite positioning communication unit. The outputs of the BLE, satellite positioning communication unit, and battery unit are all connected to the input of the MCU processing unit. The MCU processing unit is bidirectionally connected to the deduplication filtering and edge computing unit. In the BLE unit, Bluetooth broadcast signals are broadcast according to the parameters set by the channel customization unit. After connection, beacon data streams conforming to the specified protocol are collected and sent to the MCU processing unit. The deduplication filtering and edge computing unit can perform address deduplication and sorting on the collected beacons. Devices can be filtered by signal RSSI value, device name, or company ID. Devices that do not conform to the specified protocol can be filtered. The satellite positioning communication unit can receive satellite signals and send the longitude, latitude, speed, and altitude data to the MCU processing unit through the serial port.

[0012] As a further description of the above technical solution:

[0013] The MCU processing unit is bidirectionally connected to the channel customization unit and the data communication unit. The channel customization unit can choose to set a specific single RF Bluetooth scanning channel, such as channel 39, to avoid interference with the production line's WIFI channel. It can also choose to set a combination of scanning channels, such as channels 39 and 38. To improve scanning efficiency, it can choose whether to disable the scanning response packet following the broadcast packet of the scanning device. For easy comparison, it can choose whether to output according to the signal strength of the scanning device. The RF scanning window interval can be set to millisecond to second parameters as needed. The maximum number of devices that can be scanned at one time can be set, up to a maximum of 5000. The data communication unit can receive wireless signals to the MCU, convert the data received from the MCU into no signal and transmit it, and transmit the base station positioning information of the device to the MCU. The MCU processing unit can comprehensively process the information communication between the Bluetooth signal, the satellite positioning signal, and the data communication unit.

[0014] As a further description of the above technical solution:

[0015] The beacon establishment module includes a low-power management unit, a battery and power supply unit, a crystal oscillator and reset unit, an RFID unit, and an MCU processing unit. The outputs of the low-power management unit, battery and power supply unit, crystal oscillator and reset unit, and RFID unit are all connected to the input of the MCU processing unit. The crystal oscillator and reset unit can provide crystal oscillator signals and reset signals to the MCU. The MAC address of the RFID unit matches the Bluetooth MAC address, facilitating device location when the device battery is dead or other faults occur. The RFID unit expands the device's wireless inventory function, achieving high cost-effectiveness in the deployment of IoT devices in intelligent logistics systems. The low-power management unit is responsible for turning on and off the power supply of each module according to a certain timing sequence and increasing or decreasing the MCU operating frequency to increase or decrease the MCU power consumption. The entire device is woken up and put into sleep mode by a timer. The low-power strategy primarily involves reducing the MCU frequency and shutting down the power supplies of other modules. Upon wake-up, the power supplies for modules with long initialization times, such as the satellite positioning and communication units, and the data communication units, are turned on first. Then, the operating frequency of the MCU processing unit and other modules with rapid initialization are increased. During sleep mode, the power supplies for the high-power satellite positioning and data communication units are turned off first, followed by reducing the MCU operating frequency, and finally shutting down the power supplies of other modules. The MCU processing unit remains powered, but operates at different frequencies. A frequency conversion mode is used to further reduce power consumption.

[0016] As a further description of the above technical solution:

[0017] The MCU processing unit is bidirectionally connected to the Bluetooth Low Energy (BLE) unit, which is bidirectionally connected to the Bluetooth antenna and PA / LNA unit. The Bluetooth antenna and PA / LNA unit can amplify the uplink signal sent to the antenna and filter the downlink signal received from the antenna with low noise. The BLE unit can scan the gateway broadcast signal according to the set working mode, initiate a connection, and transmit signals to the gateway. The MCU processing unit can collect the beacon power level and process the data.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] In this invention, the beacon system operates in a short-interval scanning mode when no information is being uploaded. It only switches to a long-interval scanning mode after finding a gateway and connecting to upload information. The beacon system can clearly determine whether its information has been uploaded, ensuring reliable beacon information collection. The addition of a long-interval operating mode significantly extends battery life, contributing to low-carbon and environmentally friendly practices. It also reduces the information processing workload of the gateway, helping to lower costs. Furthermore, the beacon system features RFID electronic tag scanning, enabling radiating Bluetooth coverage on mobile devices and expanding the wireless inventory capabilities of equipment.
