In the present disclosure, the acquisition of the user information or the user data is an operation that is authorized, confirmed, or actively selected by the user.
As mentioned above, the Bluetooth Low Energy (BLE) technology has advantages of Low cost, low power consumption, and capability of implementing local direct connection with mobile devices such as mobile phones, and is currently widely applied to interconnection between intelligent devices, for example, control and data upload of intelligent devices in an intelligent home system, or data upload and terminal control in an intelligent monitoring system. When the bluetooth low energy BLE technology is applied to high concurrency scenes such as information or data reported by a plurality of terminals at the same time, the system needs to acquire the information or data reported by the plurality of terminals at the same time based on the bluetooth low energy BLE protocol. The current solution scheme is generally based on BLE broadcasting to respectively acquire information or data reported by each terminal, and the scheme has high data real-time performance, but network data collision is easily caused when the quantity of concurrent data is large, the system reliability is poor, and information reported by the terminals or equipment is easily lost.
In view of this, the present disclosure provides an information reporting method based on bluetooth, which implements fast networking by combining a CSMA mechanism with a summary acknowledgement frame, reduces the receiving/transmitting switching time of a base station, and reports information by using a TDMA mechanism, thereby avoiding collision of information reported by different terminals, and improving system reliability
Fig. 1 to 3 are flowcharts illustrating a bluetooth-based information reporting method according to an embodiment of the present disclosure. As shown in fig. 1 to fig. 3, the method for reporting information based on bluetooth includes the following steps S101 to S104:
polling a broadcast channel of the bluetooth, and polling a non-broadcast channel of the bluetooth when a standalone beacon frame is not received on the broadcast channel in step S101;
in step S102, when a networking beacon frame sent by a base station is received on a first channel of the non-broadcast channels, determining that the first channel is a networking channel;
in step S103, a carrier sense multiple access CSMA mechanism is used to send an association request to the base station on the networking channel, and an association summary confirmation frame sent by the base station is received when the superframe is finished, thereby completing networking;
in step S104, after receiving the information request frame sent by the base station based on the networking network, the information is reported in the preset time slot based on the time division multiple access TDMA mechanism until receiving the stop command sent by the base station.
In the embodiment of the present disclosure, the information reporting method based on bluetooth is applied to a terminal, where the bluetooth may be 2.4G bluetooth low energy BLE, and the terminal may be a device including a bluetooth communication module, for example, a household device such as a sound box and a fan, a personal health device such as an intelligent bracelet, an intelligent device such as a sensor, or other devices, which is not limited herein. The terminal may be a simple terminal having only information acquisition and transceiving capabilities but not information processing capabilities, or may be an intelligent terminal having both information acquisition and transceiving capabilities and information processing capabilities, which is not limited herein. The terminal can report information to the base station, and can also directly report information to the convergence terminal. The base station may be a micro mobile base station, and may also be other types of base stations, which are not limited herein. The convergence terminal can be a portable terminal such as a mobile phone, a tablet computer PAD, a Personal Digital Assistant (PDA) and the like, or a large-scale terminal such as a computer, a server and the like, and has information transceiving capability, information processing capability and information display capability. The base station and the aggregation terminal may be connected through a wired connection, such as a USB connection, or may be connected through a wireless connection, which is not limited herein.
In the embodiment of the present disclosure, when the terminal needs to report information, the terminal initializes a system of the terminal, scans a broadcast channel of bluetooth, and determines whether the terminal is in a standalone mode. And when the terminal confirms that the terminal is not in the stand-alone mode, switching to the networking mode, polling the non-broadcast channel of the Bluetooth, and detecting whether a networking beacon frame sent by the base station is received or not on the non-broadcast channel of the Bluetooth. When a networking beacon frame sent by the base station is received on a first channel in the non-broadcast channels, the polling is stopped, and it is determined that the first channel is a networking channel, where the non-broadcast channel may be a data channel or other channels, which is not limited herein.
In the embodiment of the disclosure, after the networking channel is determined, the terminal sends an association request to the base station on the networking channel by using a Carrier Sense Multiple Access (CSMA) mechanism. Specifically, the sending of the association request to the base station by using the carrier sense multiple access CSMA mechanism on the networking channel may be implemented in the following manner: the terminal firstly determines whether the networking channel is idle before reporting information, and when the networking channel is determined to be idle, the terminal sends the association request to the base station; when the association request sent by the terminal collides with association requests sent by other terminals, the terminal may resend the association request after the backoff is performed for the first random time period until the number of resending times exceeds a first threshold; the first random duration is less than or equal to the duration of the superframe, and the first threshold is a positive integer. When determining that the networking channel is not idle, the terminal may determine whether the networking channel is idle again after a second random time period, where the second random time period is less than or equal to the time period of the superframe.
In the embodiment of the disclosure, after sending the association request to the base station, the terminal waits until the end of the superframe, and if the association summary confirmation frame sent by the base station is received when the superframe is ended, it indicates that the networking is successful, so that the networking step of this information reporting is completed, and information reporting can be performed subsequently based on a networking network. And if the association summary confirmation frame sent by the base station is not received at the end of the superframe, indicating that the networking is unsuccessful, waiting for the base station to send the networking beacon frame again, and sending an association request to the base station again for networking after receiving the retransmitted networking beacon frame.
In the embodiment of the present disclosure, after successfully completing networking, the terminal receives an information request frame sent by a base station, and after receiving the information request frame sent by the base station, reports information in a preset Time slot based on a Time Division Multiple Access (TDMA) mechanism until receiving a stop command sent by the base station, where the preset Time slot is determined according to a networking network.
In this disclosure, the preset time slot is determined according to a networking network, and includes: and the preset time slot is determined according to any one of the number of the terminals in the networking network, the identity identification of the terminals in the networking network and the weight identification of the terminals in the networking network.
According to the technical scheme of the embodiment of the disclosure, the CSMA mechanism is combined with the mode of summarizing the confirmation frame to realize the rapid networking of the terminals in the non-broadcast channel of the Bluetooth, and the TDMA mechanism is combined to realize the information reporting, so that the information collision possibly caused by the fact that all the terminals report information through the broadcast channel in the current high-concurrency scene is avoided, the reliability of information transmission is improved, meanwhile, the receiving/transmitting switching time of the base station is reduced, and the information transmission efficiency is improved.
In the embodiment of the present disclosure, the information reporting method based on bluetooth may also be used in a standalone mode, that is, only a single terminal reports information, and a scenario in which multiple terminals report information at the same time is not required. At this time, because networking of a plurality of terminals is not needed, a base station is not needed to be set, and the terminals can directly report the information to the convergence terminal. As shown in fig. 2, in the standalone mode, the method for reporting information based on bluetooth includes: polling a broadcast channel of the Bluetooth, and determining that the terminal is in a standalone mode when a standalone beacon frame is received on the broadcast channel; after the terminal is determined to work in the single machine mode, the terminal can report information to the convergence terminal through a broadcast channel which receives the single machine beacon frame until a stop command sent by the convergence terminal is received, wherein the single machine beacon frame is sent by the convergence terminal. The convergence terminal may send the stop command when the time length for receiving the information is greater than or equal to a second preset time length, the received information is greater than or equal to a second preset number, and/or preset specific information is received.
According to the technical scheme of the embodiment of the disclosure, different beacon frames (networking beacon frames and single machine beacon frames) are set in different Bluetooth channels (non-broadcast channels and broadcast channels) to distinguish modes (networking reporting and single machine reporting) of information reported by the terminal, so that the configuration is simple and efficient, and the application range of the scheme is further expanded.
Fig. 3 illustrates a flowchart of a bluetooth-based information receiving method according to an embodiment of the present disclosure. As shown in fig. 4, the method for reporting information based on bluetooth includes the following steps S301 to S304:
in step S301, polling the non-broadcast channels of the bluetooth, and determining an idle first channel in the non-broadcast channels as a networking channel;
in step S302, a networking beacon frame is transmitted on the networking channel;
in step S303, receiving an association request sent by each terminal on the networking channel by using a carrier sense multiple access CSMA mechanism, and sending an association summary confirmation frame to each terminal when a superframe is finished, thereby completing networking;
in step S304, an information request frame is sent to each terminal, information reported by each terminal in a preset time slot based on a TDMA mechanism is received, and a stop command is sent to each terminal when a first preset condition is met, where the preset time slot is determined according to a networking network.
In this embodiment of the present disclosure, the information reporting method based on bluetooth is applied to a base station, where the bluetooth may be 2.4G bluetooth low energy BLE, and the base station may be a micro mobile base station or other types of base stations, and is not limited herein. The base station can receive the information reported by the terminal and can send the received information to the convergence terminal. The terminal may be a device including a bluetooth communication module, such as a sound box, a fan, and other household devices, a smart band, and other personal health devices, a sensor, and other smart devices, which are not limited herein. The terminal may be a simple terminal having only information acquisition and transceiving capabilities but not information processing capabilities, or may be an intelligent terminal having both information acquisition and transceiving capabilities and information processing capabilities, which is not limited herein. The convergence terminal can be a portable terminal such as a mobile phone, a tablet computer PAD, a Personal Digital Assistant (PDA) and the like, or a large-scale terminal such as a computer, a server and the like, and has information transceiving capability, information processing capability and information display capability. The base station and the aggregation terminal may be connected through a wired connection, such as a USB connection, or may be connected through a wireless connection, which is not limited herein.
In the embodiment of the disclosure, when the base station needs to receive information, the base station initializes a system of the base station, polls the non-broadcast channel of the bluetooth, and determines that an idle first channel in the non-broadcast channel is a networking channel. Specifically, the base station may poll the non-broadcast channels of the bluetooth, and detect whether data is received on each non-broadcast channel; and when determining that no data is received on the first channel in the non-broadcast channels, considering the first channel to be idle, and determining that the idle first channel is a networking channel. After determining the networking channel, the base station may send a networking beacon frame to the terminal on the networking channel, so that the terminal reports information after receiving the networking beacon frame.
