[0028] Embodiment 1

[0029] Figure 1 is a schematic structural diagram of a beacon system based on dual - mode communication provided by Embodiment 1 of the present invention. As Figure 1 shown, the system includes: a plurality of beacons 100. The plurality of beacons 100 communicate with each other through a private protocol. The beacon 100 is connected to a configuration device, and communication can be carried out between the beacon 100 and the configuration device through a standard communication protocol, and the standard communication protocol can be a Bluetooth communication protocol. In actual application scenarios, such as industrial safety protection, personnel approach warning, area entry detection, etc., the beacons 100 are deployed within a specific area range to perform proximity detection on personnel or devices approaching the specific area range. Among them, the configuration device includes, but is not limited to, electronic devices such as mobile phones and computers.

[0030] Figure 2 is a schematic structural diagram of a beacon provided by Embodiment 1 of the present invention. As Figure 2 shown, each beacon 100 includes a controller 110, a communication module 120, and a low - frequency transmission module 130. The controller 110 is integrated in the transceiver 111 and can be used for both Bluetooth communication and private - protocol communication between beacons, ensuring the flexibility and efficiency of system communication.

[0031] The communication module 120 is used to receive beacon configuration parameters of the configuration device; the beacon configuration parameters include a transmission time slot and a transmission power;

[0032] The controller 110 is used to perform timestamp synchronization between the plurality of beacons through a private protocol during the idle time window of the transceiver to establish a unified time reference; under the unified time reference, determine a synchronization schedule based on the transmission time slot; control the low - frequency transmission module 130 to transmit low - frequency signals based on the synchronization schedule and the transmission power to form a signal coverage area; the synchronization schedule includes a plurality of time slots, and each time slot corresponds to a transmission period of a beacon.

[0033] In the embodiment of the present invention, the communication module 120 communicates with the configuration device through a standard communication protocol and receives beacon configuration parameters of the configuration device; among them, the standard communication protocol can be a Bluetooth protocol, and the beacon configuration parameters include, but are not limited to, a transmission time slot, a transmission power, a beacon identifier, etc.; the transmission time slot includes the time slot for the beacon to transmit low - frequency signals, the transmission power is the transmission power of the low - frequency transmission module, and the beacon identifier is used to uniquely identify each beacon.

[0034] In some embodiments, optionally, the communication module 120 is further used to authenticate the configuration device, and terminate the connection with the configuration device in case of failed authentication.

[0035] Specifically, the configuration device sends an authentication request to the communication module. The communication module 120 receives the authentication request, extracts the authentication information, and verifies the authentication information according to predefined verification rules. If the verification is passed, parameter configuration is performed on the configuration device side. If the verification fails, the connection with the configuration device is terminated. Among them, the verification rules can be to verify whether the username and password match, or to verify whether the certificate is valid and not expired, or to verify whether the token is legal and not expired.

[0036] Exemplarily, Figure 3 is a configuration flowchart of a beacon provided in Embodiment 1 of the present invention. As Figure 3 shown, the communication module of the beacon is Bluetooth-connected to the configuration device. The communication module authenticates the configuration device. When the authentication is passed, parameter configuration of the beacon is performed on the configuration device side. The beacon configuration parameters include beacon identification, transmission power, transmission time slice, etc. When the authentication fails, the connection with the configuration device is terminated.

[0037] Among them, the private protocol between beacons can be a 2.4G private protocol. In the embodiment of the present invention, the controller 110 performs timestamp synchronization between multiple beacons 100 through the private protocol during the idle time window of the transceiver 111 to establish a unified time reference; under the unified time reference, a synchronization schedule is determined based on the transmission time slice; where the synchronization schedule includes multiple time slices, each time slice corresponds to the transmission period of a beacon, and multiple beacons 100 can transmit low-frequency signals according to the transmission timing in the synchronization schedule. Further, the low-frequency transmission module 130 is controlled to transmit low-frequency signals according to the transmission timing and transmission power of the synchronization schedule to form a signal coverage area. The signal coverage area is used for area proximity detection of a set area.

[0038] It can be understood that the coverage range of the signal coverage area is proportional to the power level of the transmission power. The greater the power level of the transmission power of the low-frequency transmission module 130, the larger the coverage range of the signal coverage area. By adjusting the transmission power of the low-frequency transmission module, precise adjustment of the coverage range is achieved, avoiding over-coverage of the signal and achieving the effect of clear signal boundaries.

[0039] Based on the above embodiments, optionally, the process of timestamp synchronization between the multiple beacons includes: sending a time synchronization request from a first beacon to a second beacon, so that the second beacon adjusts the clock of the second beacon based on the timestamp information in the time synchronization request to establish a unified time reference; where the first beacon is the master beacon / a slave beacon that has completed timestamp synchronization, and the second beacon is a slave beacon that has not completed time synchronization.

[0040] Among them, the master beacon can be any beacon in the beacon system, and the slave beacon is other beacons except the master beacon. In the embodiment of the present invention, during the idle time window of the beacon transceiver, the first beacon sends a time synchronization request to the second beacon. The second beacon receives the time synchronization request from the first beacon and records the local timestamp information when the request is received. Based on the timestamp information in the time synchronization request and the local timestamp information, the time deviation between the two is calculated. According to the calculated time deviation, the second beacon adjusts its local clock to make the clock of the second beacon consistent with that of the first beacon.

[0041] Exemplarily, taking three beacons as an example for the beacon system Figure 4 is a flowchart of time synchronization between beacons provided in Embodiment 1 of the present invention. As Figure 4 shown, Beacon 1 sends a time synchronization request to Beacon 2, and Beacon 2 performs timestamp synchronization after receiving the time synchronization request. The already time-synchronized Beacon 2 can send a time synchronization request to Beacon 3, and Beacon 3 performs timestamp synchronization after receiving the time synchronization request, thereby establishing a unified time reference.

[0042] On the basis of the above embodiment, optionally, the beacon further includes a power management module 140, which is connected to the main controller 110, the communication module 120, and the low-frequency transmission module 130, and is used to supply power to each module and perform power consumption management.

[0043] In an embodiment of the present invention, the power management module 140 first ensures that all key components in the beacon system can obtain stable and reliable power supply. It converts the electrical energy provided by an external power source (such as a battery or a power adapter) into the voltage and current levels required by each module through an appropriate power conversion circuit. In addition, the power management module 140 can also optimize the power consumption performance of the beacon through a series of strategies and technologies. Specifically, the power management module 140 adopts efficient power conversion technologies, such as switching regulators or linear regulators, to reduce the losses during the power conversion process. By optimizing the design and working mode of the conversion circuit, the power management module can improve the overall power conversion efficiency, thereby extending the battery life of the beacon. Optionally, the power management module 140 can dynamically adjust the power consumption levels of each module according to the working state and load requirements of the beacon. For example, when the beacon is in an idle state, the power consumption of the communication module and the low-frequency emission module can be reduced to save electrical energy. When the beacon needs to perform a specific task, such as emitting a low-frequency signal or communicating, the power management module will correspondingly increase the power consumption levels of the relevant modules. Optionally, for a beacon powered by a battery, the power management module 140 can also be responsible for the charge and discharge control of the battery. Through an intelligent charging management strategy, the power management module can extend the service life of the battery and reduce the damage to the battery caused by overcharging or over-discharging. Optionally, the power management module 140 supports multiple energy-saving modes, such as standby mode, sleep mode, etc. When the beacon does not need to work frequently, it can be switched to the energy-saving mode to reduce power consumption. When the beacon needs to resume work, the power management module can quickly wake up the system from the energy-saving mode and restore it to the normal working state.

[0044] Based on the above embodiments, optionally, the system further includes at least one low-frequency signal receiving device, which is configured to receive low-frequency signals transmitted by at least one beacon, determine the position information of the low-frequency signal receiving device based on the low-frequency signals, perform area proximity detection based on the position information, and generate a proximity alarm message if the receiving device is within a preset area.

[0045] Among them, the low-frequency signal receiving device can be worn by a staff member or set on a mobile device. In an embodiment of the present invention, the low-frequency signal receiving device receives low-frequency signals transmitted by at least one beacon, determines the position information of the low-frequency signal receiving device based on the low-frequency signals, and performs area proximity detection based on the position information to determine whether the staff member or the mobile device enters the area covered by the low-frequency signals. If the receiving device is within a preset area, a proximity alarm message is generated. Among them, the preset area can be a dangerous area or a specific area, which is set by those skilled in the art according to the specific scenario and is not limited here.

[0046] In some embodiments, optionally, the low-frequency signal receiving device may be disposed within the signal coverage area; the low-frequency signal receiving device is configured to receive the low-frequency signal, and when the signal strength of the low-frequency signal meets a preset area proximity detection condition, a proximity alarm message is generated.

[0047] Wherein, the preset area proximity detection condition may be a signal strength threshold or a change rate threshold of the low-frequency signal received by the low-frequency signal receiving device to determine whether an object or device is approaching the beacon; the signal strength threshold or the change rate threshold is precisely set by those skilled in the art according to the actual application scenario, the distance between the beacon and the receiving device, possible interference factors, etc. In the embodiments of the present invention, when a mobile device or a staff member approaches the beacon, due to the change in the signal propagation path and the influence of signal attenuation, the signal strength of the low-frequency signal received by the low-frequency signal receiving device will change. The low-frequency signal receiving device receives the low-frequency signal, detects the signal strength of the low-frequency signal, and when the signal strength of the low-frequency signal meets the preset area proximity detection condition, a proximity alarm message is generated. For example, when the signal strength suddenly increases or exceeds a preset threshold, it can be considered that an object or device is approaching the beacon.

[0048] Based on the above embodiments, optionally, the communication architecture of the system includes a configuration layer, a synchronization layer, and a broadcast layer; the configuration layer is used to implement standard communication protocol communication between the beacon and the configuration device, the synchronization layer is used to implement private protocol communication between the multiple beacons, and the broadcast layer is used to implement information broadcast through a 125KHz low-frequency signal.

[0049] In the embodiments of the present invention, the communication architecture of the beacon system based on dual-mode communication includes a configuration layer, a synchronization layer, and a broadcast layer. Among them, the configuration layer uses standard communication protocol communication to communicate between the beacon and the configuration device to implement parameter configuration of the beacon. The synchronization layer uses a private protocol between the beacons to communicate between the beacons to implement timestamp synchronization between the beacons. The broadcast layer implements information broadcast through a 125KHz low-frequency signal. The low-frequency signal has the characteristics of long propagation distance and strong penetration, enabling information to be received within a large range, which is of great significance for application scenarios that require wide coverage.

[0050] The technical solution of this embodiment synchronizes timestamps between the multiple beacons through a private protocol in the idle time window of the transceiver to establish a unified time reference; under the unified time reference, a synchronization schedule is determined based on the transmission time slice; based on the synchronization schedule and the transmission power, the low-frequency transmission module is controlled to transmit a low-frequency signal to form a signal coverage area. Precise synchronization at the microsecond level is achieved through a private protocol, solving the problem that the traditional solution lacks a time synchronization mechanism and signal conflicts are likely to occur in the operation of multiple beacons, ensuring the reliability of the collaborative work of multiple beacons.
