Description

Technical Field

[0001] The present invention relates to the field of Bluetooth gateways, and in particular to a low-power Bluetooth gateway and a control method thereof. Background Art

[0002] There are two types of Bluetooth gateways on the market. One is a Bluetooth chip that works with 4G or WIFI. Its main work is to use Bluetooth to scan or actively connect to the terminal, and transmit the terminal data intact to the cloud server through 4G or wifi. Disadvantages: The function is relatively simple and it only serves as a bridge for data transmission.

[0003] The other is a computing processor equipped with a Bluetooth module, 4G and WIFI to work. The main work content is that the central processor controls the Bluetooth module, uses Bluetooth scanning or actively connects to the terminal, obtains data, and performs data computing, processing, analysis and storage by itself. The processed data is uploaded to the cloud server via wifi or 4G. Disadvantages: Although the edge computing function has been added to share the pressure on the server, the power consumption is very high, so it needs to be connected to the household electricity to work. In this case, the household power supply is suddenly cut off, and the power-on is easy to cause the gateway to work abnormally. In addition, there are only two ways to start the gateway, one is to start it up by default when it is powered on, and the other is to press the power button to start it up. Both of these have disadvantages. The default power-on will cause the gateway to be unable to control the shutdown after layout, and the gateway can only be manually dismantled to stop working. The second is that the power-on needs to press the power button to start it up. In this case, there will be a gateway that has been well laid out. Due to abnormal power outages, personnel must press the power button to start it up, which brings great inconvenience to maintenance. Summary of the invention

[0051] Example 2

[0052] See also Figure 1-2 The embodiment of the present application provides a control method based on the above-mentioned low-power Bluetooth gateway, which includes a computing unit, a temperature sensor, a display, a Bluetooth processor, a power management module and a power supply module. The input of the Bluetooth processor is connected to the temperature sensor, and the output of the Bluetooth processor is connected to the display, so as to issue a fire warning through the display when the temperature exceeds a preset temperature; the Bluetooth processor is connected to the power supply module through the power management module, and the power management module is used to switch the Bluetooth processor to a low-power mode when the power is disconnected; the output of the computing unit is connected to the Bluetooth processor; the computing unit includes a gateway module and a computing processor, and the gateway module is used for the computing processor to connect to a cloud server, and the input of the Bluetooth processor is connected to the computing processor;

[0053] The specific steps include:

[0054] S1: The above Bluetooth processor sends broadcast data to set Bluetooth scanning to be on or off. If Bluetooth scanning is currently off, it is in low power consumption mode.

[0055] S2: Determine whether external power supply is provided. If it is determined to be yes, the computing processor switches the low power consumption mode to the high computing mode, i.e., starts Bluetooth scanning. Otherwise, the low power consumption mode is maintained.

[0056] S3: the computing processor obtains the broadcast data through the Bluetooth processor, and performs data analysis, computing and storage;

[0057] S4: the computing processor reports the processed broadcast data; determines whether there is data to be sent, and if it is determined that there is data, the computing processor classifies and analyzes the command, connects to the designated terminals one by one, and sends the data;

[0058] S5: Repeat step S3; switch to the power supply module to supply power, then turn off the computing processor and return to step S1.

[0059] In some embodiments of the present invention, the above S2 also includes the following step S2-1: when it is determined that the power supply is not external, shut down or start the operation server and the cloud server to interact with the data at intervals; when it is determined that the power supply is not external, upload the data to the above cloud server through the 4G / 5G module.

[0060] In some embodiments of the present invention, the above S2 also includes the following step S2-2: when it is determined that external power supply is provided, it is determined whether the above-mentioned computing processor is automatically turned on, and when it is determined to be yes, the above-mentioned low power consumption mode is turned on for Bluetooth scanning, that is, it is switched to high computing mode, otherwise the above-mentioned computing processor is turned on through the above-mentioned gateway module.

[0061] In some embodiments of the present invention, the above S2 further includes the following step S2-23: the above gateway module controls the above operation processor to start up through the above Bluetooth processor, and checks the working status of the above operation processor.

[0063] In some embodiments of the present invention, the above S4 also includes the following step S4-1: the above-mentioned computing processor periodically reports the processed above-mentioned Bluetooth data according to the above-mentioned cloud server settings.

[0064] The power supply module includes an external power supply and a battery. The Bluetooth processor is powered by an external power supply and operates normally. The default is low power mode, Bluetooth broadcast is automatically turned on, and the configuration parameters are set whether to turn on Bluetooth scanning. The Bluetooth processor switches modes according to the power supply status. When the external power supply is used, the Bluetooth processor determines whether to start the computing processor according to the configuration parameters of the power supply status and switches to high computing mode. When the Bluetooth processor is not powered by an external power supply but powered by a battery, it remains in low power mode, and the configuration parameters are set to turn off or start the computing processor at intervals to interact with the cloud service, and the computing processor is specifically configured to be turned on at a high frequency or a low frequency to complete the work task. When the low power mode is configured with a 4G / 5G module, data can be reported directly through the 4G / 5G module. Regardless of the high computing mode or the low power mode, the working logic is the same. The computing processor obtains the terminal Bluetooth broadcast data from the Bluetooth processor in real time, and performs processing, analysis, computing, storage, and other tasks. The computing processor periodically reports the processed Bluetooth data according to the cloud server setting requirements, specifically by selecting the specific data you want, informing the gateway, and the gateway performs data screening and reports the acquired specific data to the server. And process the data in the way required by the server and report it. If the server has data to send, the operation processor will classify and parse the instructions and send them to the terminal one by one through the Bluetooth processor. The Bluetooth processor is compatible with different terminals. In high-computing mode, when the power supply is switched, it will automatically switch to low-power mode to save energy and keep working. Mobile phones or other gateways can view and control the operation of the operation processor at any time through the Bluetooth processor, complete abnormal cause analysis, etc. The gateway module can be a button, a mobile phone or other gateway.

[0065] In summary, the embodiments of the present application provide a low-power Bluetooth gateway and a control method:

[0066] 1. The remote terminal sends Bluetooth broadcast packets and response packets in real time. The Bluetooth processor collects and filters the data after data collection. The filtered data is sent to the operation module through SPI1. The operation module analyzes the data and exchanges data according to the requirements of the cloud server after processing.

[0067] 2. The Bluetooth processor sends Bluetooth broadcast packets and response packets in real time. After the mobile phone or gateway receives them, it can connect to Bluetooth. Through UART1, it can control the computing module, input Linux commands, debug, dynamically view logs, set parameters, etc. It can also connect to the terminal through the Bluetooth processor to view the terminal data.

[0068] 3. When the cloud server needs to send data to the remote terminal, it sends the command to the computing module through the Internet. The computing module sends the data to the Bluetooth processor through UART2. The Bluetooth processor sends the command to the remote terminal through the Bluetooth connection. This enables data interaction between the server and the remote terminal.

[0069] 4. When the computing module stops working, the 4G / 5G module can be used to interact with the cloud service.

[0070] Understandably, Figure 1 The structure shown is for illustration only. The low-power Bluetooth gateway may also include Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown. Figure 1 Each component shown in the figure can be implemented by hardware, software or a combination thereof.

[0071] This application mainly adopts a dual-core system, which is divided into a low-power operation mode and a high-computation operation mode. When powered by an external power supply, it is in a high-computation operation mode, and the remote cloud server processes and analyzes data at full speed. When powered by a battery, it switches to a low-power mode, reduces the operating frequency of the computing processor, so as to maintain normal working conditions. The low-power mode runs for about 1 month under a 200mAH battery. If the computing processor is set to stop working, it can work for at least 4 months. The gateway realizes the interconnection function with mobile phones and gateways. This advantage can greatly facilitate the installation and layout of the gateway. The installer only needs to install all the gateways, and then set all the initial parameters of the gateways and connect to the cloud service through a mobile phone or a gateway. Any subsequent data changes can be modified through the mobile phone, gateway or cloud service. Through a mobile phone or other gateway, Bluetooth connects to an abnormal gateway, and then you can enter Linux commands, control the abnormal gateway, view the abnormal log, and analyze the problem. Quickly and easily implement abnormal repair. The gateway can be connected to other gateways or mobile phones via Bluetooth, set parameters on the mobile phone or cloud service, and debug and analyze the abnormal log of the gateway. There is no need to dismantle, remove the shell, wire, or even re-burn the gateway to analyze the problem like other gateways on the market.
