Technical Field

[0001] The invention belongs to the technical field of Bluetooth gateways, and in particular relates to a mobile Bluetooth gateway. Background Art

[0002] Bluetooth gateways play an important role in smart homes, industrial Internet of Things, healthcare and other fields. Existing Bluetooth gateways are all plug-in and fixed in location, which leads to a series of problems or limitations, such as limited location selection, complex installation process and difficulty in flexible adjustment.

[0003] Among them, location options are limited: Because the Bluetooth gateway needs to be connected to a power source, it must be installed near a power outlet. This may prevent it from being placed in an optimal location for signal coverage. For example, in large warehouses, factory floors, or open outdoor areas, the distribution of power outlets may not meet the ideal layout requirements for the Bluetooth gateway, thus affecting its signal reception and transmission performance for Bluetooth devices, resulting in signal blind spots.

[0004] Complex installation: Installing a plug-in Bluetooth gateway involves connecting power lines, which may require professional assistance, increasing installation costs and time. In aesthetically pleasing environments, such as smart homes, the routing of power lines can also affect the overall finish.

[0005] Difficult to adjust flexibly: Once the installation is complete, if you want to change the location of the Bluetooth gateway, you need to re-plan the power lines, which is not only troublesome, but may also require re-configuration and debugging of the network, which is not conducive to flexible adjustment and optimization according to actual usage needs.

[0006] In response to the above defects, we need to come up with a mobile Bluetooth gateway to solve the above problems, so that it can get rid of the constraints of the power socket and adjust its position at any time according to actual needs. It does not require complicated power line laying and installation process, which greatly shortens the network construction time and improves response efficiency. Summary of the Invention

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] The present invention provides Figure 1-2A mobile Bluetooth gateway shown in the figure includes a Bluetooth module, a wireless network module, a storage chip, a USB module for data export and device charging, a main control chip, a display screen and a power supply module; the Bluetooth module provides Bluetooth communication function for data transmission with Bluetooth devices; the wireless network module supports wireless network connection for providing remote data transmission and networking functions; the storage chip is used to store data; the USB module provides a USB interface, the USB module is electrically connected to the storage chip, the main control chip is electrically connected to the Bluetooth module, the wireless network module, the storage chip and the USB module respectively, the main control chip performs high-speed data transmission and command interaction with other modules through an internal bus system to comprehensively coordinate and control the operation of the system, the display screen is connected to the main control chip, and the power supply module is electrically connected to the Bluetooth module, the wireless network module, the storage chip, the USB module, the main control chip and the display screen respectively.

[0039] By integrating multiple functional modules such as the main control chip, Bluetooth module, wireless network module, storage chip, USB module, display screen and power supply module into one, a compact and fully functional mobile gateway is formed. This modular design not only improves the scalability and maintainability of the system, but also makes the data interaction between modules more efficient. It can get rid of the constraints of power sockets and can adjust the position at any time according to actual needs. There is no need for complicated power line laying and installation process, which greatly shortens the network construction time and improves response efficiency.

[0040] In order to facilitate user operation control, it also includes a button and knob unit, which is electrically connected to the main control chip. The button and knob unit provides the user with input components for operating and controlling the device, which are used for powering on, powering off, switching menus, etc., providing the user with an intuitive and convenient operation method.

[0041] In order to facilitate observation of the working status of the display device, an indicator light is also included. The indicator light is electrically connected to the main control chip. The indicator light intuitively displays the working status and connection status of the device through different lighting states (such as on and off, flashing, etc.).

[0042] The power supply module includes a battery and a battery management unit connected to the battery. The battery management unit uses a high-efficiency DC-DC converter to provide dynamic voltage adjustment for each module. The battery provides a mobile power supply for the device. The battery management unit is a circuit that monitors and manages the battery. It can monitor the battery's voltage, current, temperature and other parameters in real time to prevent the occurrence of battery overcharging, over-discharging, short circuit, etc., protect the battery safety, and optimize the battery charging and discharging process to extend the battery life. At the same time, the battery management unit can also convert the battery voltage into different voltage levels required by each module to power the system.

[0043] The battery management unit includes a protection circuit that prevents the battery voltage from exceeding a safety threshold and a multi-level voltage output circuit that provides adaptive voltages for different modules. The battery management unit is provided with a short-circuit protection mechanism. The short-circuit protection mechanism can cut off the power supply when abnormal current occurs, preventing the occurrence of battery overcharging, over-discharging, short circuit, etc., protecting the battery safety, and optimizing the battery charging and discharging process to extend the battery life.

[0044] The main control chip is set to be a low-power microcontroller using CMOS technology. The process of comprehensive coordination and control by the microcontroller is as follows:

[0045] A1. After the device is powered on, the main control chip performs initialization operations to put all modules into an operational state. The initialization operation starts the internal clock circuit to provide a stable time reference for all parts of the chip. It then loads and runs the firmware (Basic Input and Output System program), performs hardware detection and configuration on itself and each connected module (such as the Bluetooth module, wireless network module, etc.) to ensure that each module is in an operational state.

[0046] A2. Receives input signals from the button and knob units, as well as data signals transmitted from the Bluetooth module and wireless network module. For example, when a user presses a button on the device, the electrical signal generated by the button is transmitted to the input pin of the main control chip. The main control chip detects the signal and then performs the next step of processing.

[0047] The main control chip monitors the connection status of the Bluetooth module and triggers the sleep mode through the timer module of the CMOS process low-power microcontroller. The timer or interrupt mechanism is used to make the Bluetooth gateway enter the low-power sleep mode when there is no data transmission demand. At this time, most of the circuits of the main control chip stop working, and only a small amount of circuits for detecting specific events are kept in standby state. When there is a Bluetooth device connection request or data transmission, the Bluetooth gateway is awakened by the corresponding trigger signal to restore it to normal working state;

[0048] A3. The main control chip performs data analysis and processing after receiving input signals or data signals. During data analysis and processing, the main control chip uses a data compression algorithm to analyze and optimize the data processing process, eliminating redundant calculation steps and storage operations. For example, when receiving data from a sub-device, the main control chip first performs digital signal processing on the data to reduce interference signals and extract key features. For another example, when a user issues a function selection command through a key, the main control chip will determine the user's desired operation based on a preset command mapping relationship and make a corresponding decision.

[0049] A4. Based on the data analysis and processing results, the main control chip initiates data transmission or issues control instructions to the corresponding modules. For example, it sends instructions to the display screen to show the current status. If the device detects that the battery is low, it will control the indicator light to flash to alert the user.

[0050] A5. The main control chip continuously monitors the status and input signals of each module in a loop and obtains real-time device operation information, such as the Bluetooth module feedback on the connection status and the battery management module feedback on the battery power level. At the same time, each module will feedback its own status to the main control chip. The main control chip dynamically adjusts the system operation parameters and control strategies based on the feedback information to ensure stable and efficient operation of the device. When the main control chip dynamically adjusts the system operation parameters and control strategies based on the feedback information, it staggers the task execution order and time to avoid resource competition and excessive load on the main control chip caused by multiple tasks running simultaneously.

[0051] The Bluetooth module adopts the BLE protocol, uses short data packets less than 20 bytes in length, a flexible connection method with a connection interval of 50ms-200ms, and a fast link establishment mechanism with a link establishment time of less than 3ms to reduce power consumption, and adjusts Bluetooth parameters by reducing transmission power and communication rate and increasing the connection interval. The Bluetooth module is a hardware unit that realizes the Bluetooth communication function. It complies with the Bluetooth technical specifications and can establish connections with other Bluetooth devices within a short distance and perform data transmission. Its operating frequency band is in the 2.4GHz ISM band, and frequency hopping technology is used to avoid interference.

[0052] The wireless network module is primarily used to implement cellular / Wi-Fi connectivity, enabling devices to access wireless networks. This module receives and transmits wireless signals via an antenna, communicating with a wireless router or network base station. This allows collected data to be uploaded to a cloud server, and users can also remotely control the device over the network. By integrating a Bluetooth module with a wireless network module, the system achieves dual functionality, including Bluetooth communication and wireless network connectivity. This provides users with more flexible data transmission options, allowing them to transfer data with nearby devices via Bluetooth, as well as achieve remote data transmission and networking via wireless networks. This enhanced wireless communication capability gives the system broad application prospects in areas such as the Internet of Things, smart homes, and industrial automation.

[0053] The memory chip is used to store data required for system operation and data transmitted from external devices. In this system, the memory chip can store files transmitted from Bluetooth devices, system configuration parameters, device operation logs and other information, so that the device can quickly read and use them when needed.

[0054] The display screen is an important interface for users to interact with devices. It is used to display information such as the device's operating status, connection status, bound sub-devices, and parameter settings.

[0055] The mobile Bluetooth gateway, which is composed of a main control chip, a Bluetooth module, a wireless network module, a storage chip, a USB module, a display screen, buttons and knobs, indicator lights, and a power supply module, has a low-power consumption strategy at the hardware level, the software level, and the communication protocol level.

[0056] Hardware level:

[0057] 11) Choose low-power devices. Different electronic devices have significantly different power consumption during operation. Low-power devices typically utilize more advanced manufacturing processes, optimized circuit designs, and low-power operating modes, consuming less energy while performing the same functions. For example, when choosing a microcontroller (MCU), some low-power MCUs that use CMOS technology can have quiescent currents as low as microamperes or even nanoamperes, significantly reducing power consumption compared to traditional MCUs.

[0058] 12) Use high-efficiency DC-DC converters; a DC-DC converter is an electronic component that converts one DC voltage into another. A high-efficiency DC-DC converter can convert the input voltage into the voltage required by each module of the device with higher conversion efficiency, reducing energy loss during the voltage conversion process.

[0059] 13) Accurately divide the power supply voltage. Different circuit modules have different voltage requirements under different working conditions. By accurately dividing the power supply of each module and providing each module with the minimum voltage that can just ensure its stable and reliable operation, energy waste caused by providing too high a voltage can be avoided.

[0060] Software level:

[0061] 21) Intelligent wake-up algorithm: By monitoring and determining the working status of the Bluetooth gateway and utilizing timers, interrupts, and other mechanisms, the Bluetooth gateway enters a low-power sleep mode when there is no data transmission demand. At this time, most of the chip's circuits stop working, leaving only a small amount of circuits used to detect specific events in standby mode. When a Bluetooth device connection request or data transmission occurs, the Bluetooth gateway is awakened by a corresponding trigger signal, restoring it to normal working state. For example, the Bluetooth gateway can be set to detect whether there is a Bluetooth device connection request or data transmission every certain period of time (such as 1 second). If no relevant request is found in multiple consecutive detections, it enters sleep mode. When a Bluetooth device sends a connection request, the Bluetooth module generates an interrupt signal to wake up the sleeping Bluetooth gateway.

[0062] 22) Data processing optimization: Analyze and optimize the data processing flow through data compression algorithms, remove unnecessary calculation steps and data storage operations, and reduce the amount of chip operations and data access during the data processing process, thereby reducing power consumption. For example, when processing data collected by the sensor, if only the average and maximum values ​​of the data are needed, calculations can be performed directly during the collection process without storing all the collected data for calculation. This reduces the number of data storage and reading times and reduces power consumption.

[0063] 23) Task scheduling optimization: Rationally arrange the task execution order and time of the Bluetooth gateway to avoid resource competition and excessive chip load caused by multiple tasks running at the same time, so that the chip can work more efficiently and reduce the increase in power consumption caused by task conflicts and unnecessary waiting time. For example, schedule the Bluetooth data reception task and data upload task to be executed in different time periods to avoid uploading data while receiving data, and prevent the two tasks from occupying communication resources at the same time, resulting in reduced communication efficiency and increased power consumption.

[0064] Communication protocol level:

[0065] 31) Adjust Bluetooth parameters; Bluetooth parameters such as transmission power, communication rate and connection interval directly affect the energy consumption of Bluetooth communication. Reducing the transmission power can reduce the energy consumption during signal transmission; reducing the communication rate can reduce the amount of data transmitted per unit time, thereby reducing the power consumption of the chip during data processing and transmission; appropriately increasing the connection interval can make the Bluetooth device enter a low-power state during idle time, reducing energy consumption during communication. For example, in indoor short-range communication scenarios, reducing the Bluetooth transmission power from the default 4dBm to 0dBm, the communication rate from 1Mbps to 250kbps, and the connection interval from 20ms to 50ms can effectively reduce the power consumption of Bluetooth communication without affecting the communication quality.

[0066] 32) Give priority to the use of BLE protocol; Bluetooth Low Energy (BLE) protocol is a Bluetooth protocol designed specifically for low-power application scenarios. It adopts a more efficient communication mechanism and a low-power working mode, such as shorter data packets, more flexible connection methods and a fast connection establishment process. It can greatly reduce power consumption while ensuring basic communication functions.

[0067] 33) Optimize communication protocols to reduce invalid communications; by adopting technologies such as data caching and batch transmission, multiple short data packets are merged into a larger data packet for transmission, reducing the number of connection establishment and data transmission during the communication process, reducing communication overhead and energy consumption. For example, when a Bluetooth gateway communicates data with multiple Bluetooth sensors, the data collected by the sensors is first cached locally. When the cached data reaches a certain amount, the data is transmitted in batches to the Bluetooth gateway at one time, avoiding frequent transmission of short data packets and reducing energy consumption during the communication process.

[0068] Through various low-power strategies, the power consumption of the Bluetooth gateway is minimized, thereby reducing the requirement for battery capacity, making the device lighter and more convenient to adapt to various mobile scenarios;

[0069] The present invention is suitable for scenarios where the Bluetooth network needs to be used during mobility. When it is necessary to expand the coverage of the Bluetooth network or increase the number of connected devices, the expansion of the mobile Bluetooth gateway is more convenient. Only a corresponding number of mobile gateways need to be added and placed in appropriate locations to quickly achieve network expansion without having to consider issues such as power interfaces and line laying. There is no need to carry out complicated power line laying and fixed installation, which reduces hardware costs and labor costs. Especially in some temporary or experimental projects, the use of a mobile Bluetooth gateway can greatly reduce the initial deployment cost and can be reused in different projects or scenarios, thereby improving the utilization rate of the equipment. When a project is completed, the gateway can be moved to other projects for continued use, avoiding idleness and waste of equipment.

[0070] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
