[0001] This invention relates to emergency rescue, and more particularly to an emergency rescue method, emergency rescue helmet and medium based on BeiDou. Background Technology

[0002] In emergency rescue operations in the wild, there are many protective equipment options for the head. However, traditional helmets only focus on basic head impact protection and cannot be linked and controlled with existing wild rescue equipment. They cannot meet the needs of multiple functions in complex environments, especially in remote mountainous and wilderness areas where there is no public network signal. Rescuers are prone to getting lost, and command positions cannot keep track of their location and status in real time, making it impossible to establish effective communication. This affects command and dispatch, resulting in low rescue efficiency and threatening the safety of rescuers. Summary of the Invention

The main control module is electrically connected to the positioning module and communicates with the BeiDou satellite via the BeiDou communication module. The main control module communicates with a portable terminal app via the Bluetooth module. The battery module is electrically connected to the main control module, the positioning module, the BeiDou communication module, and the Bluetooth module.

[0039] Figure 2 The second flowchart of the emergency rescue method based on BeiDou provided by this invention. Detailed Implementation

[0040] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0041] Example 1

[0042] This invention primarily addresses the rescue needs in outdoor construction and forest fire fighting by intelligently modifying existing helmets to integrate BeiDou positioning and communication functions. This creates an emergency rescue helmet with BeiDou positioning and communication capabilities, enabling rescuers to report their location. Simultaneously, by incorporating Bluetooth, it allows for monitoring of the user's physical condition, promptly detecting any abnormalities for timely rescue and improving efficiency. Furthermore, this invention enables low power consumption and extended battery life through mode switching, which is beneficial for rescue needs in the wild or outdoors. Specifically, this invention provides a preferred embodiment, a BeiDou-based emergency rescue method, such as... Figure 1 As shown, it includes:

[0043] Step S1: Initialize the system and start the main control module inside the emergency rescue helmet.

[0044] Specifically, the BeiDou-based emergency rescue method disclosed in this invention is applied to a BeiDou-based emergency rescue helmet. The helmet has a main control board integrating a main control module, a positioning module, and a BeiDou communication module. The main control module communicates with the positioning module to locate the helmet and obtain its positioning data. Based on this data, the user's exact location is determined. The main control module communicates with the BeiDou satellite system and then with a remote service center. This allows for remote communication and uploading of positioning data to the remote service center, thus reporting the user's trajectory.

[0045] Meanwhile, the emergency rescue helmet also contains a battery module to power the main control module, positioning module, and Beidou communication module. A power button is also located on the helmet itself to control the power supply and thus initialize the system.

[0046] Step S2: Activate the positioning module and Beidou communication module through the main control module, and then obtain positioning data through the positioning module and synchronize satellite time through the Beidou communication module.

[0047] Specifically, the positioning module in this invention is a BeiDou RNSS module, and the BeiDou communication module is a BeiDou RDSS module. RDSS is an active positioning system where user equipment needs to send a response signal to the satellite. An external system (such as a remote service center) then performs distance measurement and position calculation. Data communication between RDSS and BeiDou satellites is achieved, and RDSS can also locate the user equipment. In this embodiment, the communication function of RDSS is used to achieve data communication between the main control module and the BeiDou satellites.

[0048] RNSS is a passive positioning system where user equipment (UE) can autonomously calculate its position, velocity, and navigation parameters by receiving signals from at least four satellites. UE can independently complete all calculations to achieve positioning, and its positioning accuracy is higher than that of RDSS. Therefore, this invention uses BeiDou RNSS to locate UEs and then uses BeiDou RDSS to communicate with BeiDou satellites. This not only achieves UE positioning but also solves the problem of emergency rescue helmets being unable to communicate with remote service centers due to the lack of public network signal.

[0049] Furthermore, after the main control module inside the emergency rescue helmet is powered on, the positioning module and the Beidou communication module are activated through the main control module, so that the positioning module can access the Beidou satellite to save ephemeris, realize terminal entry into the station, and then obtain positioning data; at the same time, the Beidou communication module communicates with the Beidou satellite to synchronize satellite time.

[0050] Step S3: The main control module generates a positioning message based on the positioning data and uploads the positioning message to the remote service center through the Beidou communication module; after the message is sent, the emergency rescue helmet will enter sleep mode after a delay and the sleep time will start.

[0051] Specifically, the main control module generates a positioning message based on the positioning data obtained by the positioning module, and forwards the positioning message to the Beidou satellite through the Beidou communication module, and then forwards it to the remote service center through the Beidou satellite to realize the reporting of positioning data; at the same time, after the message is sent, the emergency rescue helmet enters the sleep mode after a first preset time delay, and the sleep time is started.

[0052] In other words, this invention significantly reduces the power consumption of various modules within the emergency rescue helmet by putting it into sleep mode after the location message is reported, thereby extending the helmet's lifespan. Under normal circumstances, the positioning module and BeiDou communication module consume a large amount of power when constantly activated, quickly depleting the helmet's battery and affecting its usage time. Therefore, this invention reduces the power consumption of the positioning and BeiDou communication modules by setting a sleep mode, thus extending the helmet's operating time. Simultaneously, the sleep time is recorded in real time when the helmet enters sleep mode.

[0053] In addition, to ensure accurate message transmission, the present invention delays the emergency rescue helmet into sleep mode for a preset time after the message is sent. For example, the emergency rescue helmet can be put into sleep mode 2 seconds after the message is sent.

[0054] More specifically, the sleep mode in this invention refers to putting all modules within the emergency rescue helmet into a low-power state. For example, this involves turning off the power clocks of all modules except the timer to reduce power consumption, waiting for the main control module to wake up the other modules and exit sleep mode at a corresponding time. Through the message reporting method of this invention, the emergency rescue helmet can operate continuously for up to 72 hours in alarm mode, significantly extending its usage time and making it more suitable for outdoor rescue operations.

[0055] Step S4: When the sleep time meets the first preset condition, the main control module wakes up the positioning module to obtain positioning data, and then the positioning module enters sleep mode again.

[0056] By waking up the positioning module first, positioning information can be obtained more effectively when the reporting frequency arrives, reducing the delay in reporting frequency.

[0057] Step S5: When the sleep time meets the second preset condition, wake up the Beidou communication module through the main control module and synchronize the satellite time.

[0058] Specifically, after the emergency rescue helmet enters sleep mode, this invention also achieves positioning and satellite time synchronization by pre-awakening the positioning module and the BeiDou communication module. First, after the message is uploaded, the invention puts the emergency rescue helmet into sleep mode to reduce the overall power consumption of the helmet, especially the positioning and BeiDou communication modules, which consume a significant amount of power. By putting them into sleep mode to reduce power consumption, the battery life of the emergency rescue helmet can be extended. Then, before the sleep mode ends, the positioning module and the BeiDou communication module are pre-awakened sequentially to achieve positioning and satellite time synchronization for the emergency rescue helmet. Since the positioning module uses the BeiDou RNSS module, which can achieve passive positioning, it is first awakened to receive satellite signals to update the ephemeris and thus the positioning data. After the positioning data update is completed, it is put back into sleep mode. Then, the BeiDou communication module is awakened to synchronize and update the satellite time, preparing for the subsequent upload of positioning data. Therefore, the BeiDou communication module also needs time to synchronize and update the satellite time. The BeiDou communication module is woken up in advance before the emergency rescue helmet ends its dormancy to synchronize and update the satellite time. In this way, after the entire emergency rescue helmet is woken up, data transmission can be realized quickly, which can save power consumption of the emergency rescue helmet and also quickly forward data packets.

[0059] Step S6: Based on the message reporting frequency, exit the emergency rescue helmet from sleep mode and reset the sleep time to zero. Then, execute step S2 until the emergency rescue helmet is powered off or other interruption operations are performed.

[0060] Specifically, when the emergency rescue helmet reaches the required message reporting frequency, it exits sleep mode and resets the sleep timer. It then acquires location data via the positioning module and connects to the BeiDou satellite communication module. A positioning message is then generated for data transmission. After the message is sent, the emergency rescue helmet re-enters sleep mode, restarting the sleep timer.

[0061] More preferably, the present invention first activates the positioning module to enable terminal access and achieve positioning, and then activates the BeiDou communication module to achieve satellite time synchronization and data communication. That is, the activation time of the positioning module is earlier than the activation time of the BeiDou communication module. More specifically, the positioning module is a BeiDou RNSS module, and the BeiDou communication module is a BeiDou RDSS module.

[0062] The wake-up time for the positioning module, also known as the BeiDou RNSS module, can be set based on its positioning calculation time and total sleep time. For example, the wake-up time can be set to 20 seconds before exiting sleep mode. Simultaneously, the wake-up time of the positioning module must precede the wake-up time of the BeiDou communication module. The wake-up time for the BeiDou RDSS module can be determined based on its docking time with a geostationary satellite. For instance, since docking with a geostationary satellite typically takes at least 7-8 seconds, the wake-up time can be set to 8 seconds before the end of sleep mode, ensuring synchronization with satellite time before the message reporting frequency is reached. In other words, the first preset condition is that the sleep time equals the total sleep time - 20 seconds, and the second preset condition is that the sleep time equals the total sleep time - 8 seconds. Alternatively, a specific threshold for the wake-up time can be set directly based on the sleep time.

[0063] More preferably, the present invention also provides a tracking mode and an alarm mode for the emergency rescue helmet. The tracking mode refers to the location reporting mode when the emergency rescue helmet is working normally, and the alarm mode refers to the alarm reporting mode triggered when the user presses the SOS alarm button or when the emergency rescue helmet detects water damage.

[0064] Furthermore, step S2 is followed by:

[0065] Step S7: Obtain the working mode of the emergency rescue helmet. If the working mode is tracking mode, execute S3; if the working mode is alarm mode, execute step S8.

[0066] Step S8: Obtain body status data through the main control module and generate an alarm message based on the positioning data and body status data, and upload the alarm message to the remote service center through the Beidou communication module; after the alarm message is sent, delay for a preset time to put the emergency rescue and helmet into sleep mode, and start timing the sleep time, and then execute step S4.

[0067] The physical condition data includes the user's body temperature, heart rate, and blood pressure. Specifically, this data can be acquired through wearable devices worn by the user, such as smart bracelets, which connect to the main control module of the emergency rescue helmet via Bluetooth. Of course, other devices can also be used to collect this data; the appropriate device can be selected based on the specific needs.

[0068] In other words, when the emergency rescue helmet is in tracking mode, it uses a normal cycle of sending messages, going to sleep, waking up, and sending messages to locate and track the user. When the emergency rescue helmet is in alarm mode, in addition to reporting location data, it also acquires and reports the user's physical condition data, so that the remote service center can determine the user's abnormal situation based on the user's physical condition data and then promptly initiate rescue.

[0069] Additionally, regarding the reporting frequency in step S5, when the emergency rescue helmet is in tracking mode, the user is undergoing normal location tracking. Therefore, the reporting frequency follows the system's default reporting channel or the BeiDou card communication frequency used with the BeiDou communication module. Generally, the reporting frequency in normal tracking mode is 120 seconds. However, when the emergency rescue helmet is in alarm mode, the system records the alarm time when the helmet enters alarm mode. If the alarm time does not exceed the preset alarm time, the system reports messages according to the first preset reporting frequency; if the alarm time exceeds the preset alarm time, the system reports messages according to the second preset reporting frequency. That is, when the system reaches the corresponding reporting frequency, the emergency rescue helmet exits sleep mode.

[0070] More specifically, the alarm modes include SOS alarm mode and water-fall alarm mode. Similarly, when the alarm mode is SOS, the alarm message is an SOS alarm message. This can be achieved by installing an SOS alarm button on the emergency rescue helmet, allowing the user to trigger an alarm with a single press. When the alarm mode is water-fall alarm mode, the alarm message is a water-fall alarm message. This can be achieved by installing a water-fall detection module on the emergency rescue helmet. When the helmet falls into water, the water-fall detection module generates an electrical signal and sends it to the main control module. The main control module detects this signal and activates the water-fall alarm mode.

[0071] Preferably, the alarm mode switching of the present invention can also be switched according to the user's physical condition. Specifically, the main control module acquires the user's physical condition data and performs anomaly analysis based on the data to determine whether the user's body is in an abnormal state. If so, a voice alarm signal is sent to the user via voice and a periodic vibration reminder is provided. Simultaneously, after a second preset time delay following the sending of the voice alarm signal, the emergency rescue helmet enters alarm mode. That is, by detecting anomalies in the user's physical condition data, the system determines whether the user's physical condition is normal. For example, the main control module can periodically poll the user's wearable device to obtain parameters such as the user's body temperature, heart rate, and blood pressure, and perform anomaly detection on these parameters. Once a decrease in body temperature, a drop in heart rate, or excessively low or high blood pressure is detected, the user is promptly reminded via voice and vibration. Simultaneously, after a second preset time delay, the emergency rescue helmet enters alarm mode to begin reporting alarm messages. For example, when any one or more of the heart rate, body temperature, or blood pressure exceeds a preset threshold, a voice prompt will be continuously activated for 60 seconds, such as: "Attention!" If the user experiences abnormal physical conditions such as hypothermia, the device will vibrate to alert them. After the vibration period ends, the emergency rescue helmet will enter alarm mode and report an alarm message, including the user's location data, physical condition data, and abnormal results. This information will allow the remote service center to take further rescue measures based on the alarm message. If a misjudgment occurs due to other reasons, the user can cancel the alert within 60 seconds by pressing the corresponding function button to avoid entering alarm mode due to misjudgment.

[0072] More preferably, the emergency rescue helmet of the present invention also features an emergency distress mode. This mode enables distress calls and facilitates faster rescue operations. Specifically, when the emergency rescue helmet enters emergency distress mode, the main control module acquires location data in real time through the positioning module and simultaneously acquires the user's physical status data. It then generates an emergency distress message and uploads it to the remote service center via the BeiDou communication module. This allows the remote service center to send emergency distress information to users of the emergency rescue helmet within a preset distance of the distressed individual and / or to call the corresponding rescue unit to notify them of the emergency distress message. The emergency distress information includes the distressed individual's location, the distance and direction between the distressed individual and rescue personnel or units, and the required rescue supplies. When the emergency rescue helmet is in emergency distress mode, the positioning module and BeiDou communication module remain active and do not enter a dormant state, allowing rescuers to quickly locate the distressed individual in real time for rapid rescue. Specifically, when a user needs to call for help, they can use the one-click SOS button on the emergency rescue helmet to put the helmet into emergency SOS mode, report an emergency SOS message, and set a SOS icon in the emergency SOS message to indicate that the situation is urgent and to seek help from nearby partners.

[0073] More preferably, the emergency rescue helmet is also equipped with a voice module and a voice switch button. By activating the voice module on the emergency rescue helmet, such as the microphone, voice commands can be received, and corresponding operations, such as mode switching, can be performed based on the voice commands. When the user has difficulty operating the helmet, they can use voice commands to switch modes or issue commands.

[0074] More preferably, in order to realize the parameter configuration inside the emergency rescue helmet, the present invention also configures a corresponding terminal APP for the emergency rescue helmet. The main control module is connected to the terminal APP via Bluetooth. The terminal APP can be installed on the user's portable mobile terminal to realize parameter configuration, voice control, software upgrade, etc. of the emergency rescue helmet through the operation of the terminal APP.

[0075] Furthermore, this invention can also upgrade the terminal APP via Bluetooth. Specifically, by pressing the corresponding function button, the emergency rescue helmet is put into configuration mode. At this time, the main control module wakes up the Bluetooth module and connects to the terminal APP via Bluetooth. For example, in the initial stage: configuration parameters, slave mode, and Bluetooth name initialization are entered into AT command mode via Bluetooth; then in the connection stage: the Bluetooth mode is put into sleep mode to wait for Bluetooth connection requests, and the Bluetooth connection status pins are monitored in real time to see if the connection is successful. If so, the data parsing and transparent transmission mode is entered; after entering the data transparent transmission mode, the serial port interrupt receives the update command transmitted by Bluetooth and transmits the update command to the Beidou communication module, which then uploads it to the remote service center. The remote service center transmits the update data to the Beidou communication module via Beidou satellite, so that the main control module transmits the update data to the terminal APP via Bluetooth to upgrade the terminal APP's software and verify the update to complete the software upgrade. The software upgrade of the terminal APP of this invention is achieved by using the Beidou communication of the emergency rescue helmet, which enables the software upgrade of the terminal APP even in the absence of public network or with poor network signal.

[0076] This invention integrates a BeiDou positioning and communication module, a Bluetooth module, and a voice module into an existing wilderness rescue helmet. This enables automatic trajectory reporting upon power-on. Furthermore, it utilizes various function buttons and detection modules to trigger alarm modes for automatic alarm message reporting. By employing a cycle of sleep mode and pre-wake-up of the positioning and BeiDou communication modules, the helmet's lifespan can be significantly extended, making it more suitable for outdoor rescues. This invention also allows for software upgrades of the terminal app via Bluetooth, enabling software updates even without a public network connection. This invention is particularly suitable for outdoor forests, firefighting operations, and areas with poor network signal or no public network access, enabling personnel location tracking and alarm reporting.

[0077] Example 2

[0078] Based on Embodiment 1, the present invention also provides another embodiment, a BeiDou-based emergency rescue device, including a memory and a processor. The memory stores an emergency rescue program that runs on the processor. The emergency rescue program is a computer program. When the processor executes the emergency rescue program, it implements the steps of the BeiDou-based emergency rescue method as used in Embodiment 1 of the present invention.

[0079] Example 3

[0080] Based on Embodiment 1, the present invention also provides another embodiment: a computer-readable storage medium storing an emergency rescue program thereon. The emergency rescue program is a computer program, and when executed by a processor, it implements the steps of a BeiDou-based emergency rescue method as described in Embodiment 1 of the present invention.

[0081] Example 4

[0082] Based on Embodiment 1, the present invention also provides a BeiDou-based emergency rescue helmet, including a helmet body, a main control module, a positioning module, a BeiDou communication module, a Bluetooth module, a battery module, and multiple function buttons on the helmet body.

[0083] The function buttons include an SOS button, an emergency call button, and a power button. The number of buttons can be set according to needs. Different pressing methods can also be set for a single function button to perform different functions. For example, for the SOS button, a short press can switch to SOS alarm mode, while a long press can switch to emergency call mode. The specific operation can be set according to actual needs.

[0084] The main control module is electrically connected to the positioning module and communicates with the BeiDou satellite via the BeiDou communication module. The positioning module uses the BeiDou RNSS module, and the BeiDou communication module uses the BeiDou RDSS module. The positioning of the emergency rescue helmet is achieved by using the BeiDou RDSS module, and the message reporting is achieved through the communication function between the BeiDou RDSS module and the BeiDou satellite.

[0085] More preferably, the main body of the emergency rescue helmet is also equipped with a water-fall detection module. Specifically, two detection points are inserted into the outer surface of the emergency rescue helmet. When the emergency rescue helmet falls into water, the two detection points will short-circuit due to the water, triggering an interrupt signal. This causes the water-fall detection module to generate an electrical signal. At this time, the main control module can determine whether a water-fall has been triggered based on the electrical signal, and then determine whether to enter the water-fall alarm mode.

[0086] Furthermore, the main control module communicates with the portable terminal APP via Bluetooth, enabling interaction with the user through the terminal APP, such as parameter configuration, software upgrades, and data display.

[0087] The battery module is electrically connected to the main control module, positioning module, Beidou communication module, and Bluetooth module to provide power to these different modules.
