[0003] In the related technology, by distinguishing the device state into working state or sleeping state, corresponding energy-saving measures are implemented. In the working state, each component of the device operates with high energy consumption, which can ensure the rapid response and functional integrity of the device; in the sleeping state, the device enters a low-power sleep mode until it is reawakened.

[0004] However, the above energy consumption management method does not dynamically adjust the power consumption in combination with the status changes of the positioning tag device. There may be a problem that the usage status of the positioning tag device is inconsistent with the actual usage status, resulting in insufficient accuracy of energy consumption control, and further resulting in additional energy waste.

[0053] The energy-saving method, device and storage medium of the positioning tag device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0054] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0055] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0056] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0057] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0058] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0059] With the rapid development of the Internet of Things and communication technology, positioning tag devices are increasingly used in various fields, but the energy consumption problem of positioning tag devices has become a technical problem to be solved. In related technologies, energy consumption management usually relies on a fixed sleep strategy, that is, when the positioning tag device is in working state, each component runs with high energy consumption to ensure the rapid response and functional integrity of the positioning tag device; in the sleep state, the positioning tag device enters a low-power sleep mode until it is reawakened.

[0060] Although the above energy management mechanism can achieve energy-saving effects, it fails to fully utilize the changes in the action state of the positioning device to dynamically adjust the power consumption. When the positioning tag device is in a stationary or low-speed motion state, the frequency and accuracy requirements of its positioning are reduced. However, according to the fixed sleep strategy, the positioning tag device still wakes up according to the preset time or conditions, resulting in additional energy waste.

[0061] In this context, in order to solve the problem of inflexible energy management mechanism and resulting energy waste in related technologies, the present application provides an energy-saving method, device and storage medium for positioning tag equipment. The implementation method of the embodiment of the present application is described in detail below in conjunction with the drawings in the specification.

[0062] like Figure 1 FIG. 1 is a schematic diagram of signal transmission of a positioning tag device provided in an embodiment of the present application. The positioning tag device 100 may include: an inertial sensor 101 and a main control processor 102 .

[0063] Among them, the above-mentioned inertial sensor 101 is used to detect the state change of the device; the main control processor 102 is used to receive the device state change detected by the inertial sensor; I1, I2, and I3 respectively represent the acceleration changes of the positioning tag device 100 along the X-axis, Y-axis, and Z-axis.

[0064] Exemplarily, the positioning tag device 100 can detect the acceleration change of the device through the inertial sensor 101 and convert it into an electrical signal. When the detected acceleration change exceeds a preset threshold, an interrupt signal is sent. The main control processor 102 receives the interrupt signal sent by the inertial sensor 101 and dynamically sleeps the positioning tag device 100 through the trigger frequency of the interrupt signal.

[0065] like Figure 2 As shown, it is a configuration process of a positioning tag device after power-on provided by an embodiment of the present application:

[0066] S201, loading system firmware and driver.

[0067] Among them, the system firmware contains the boot program for locating the tag device and the basic code and control logic required for the device to operate; the driver is the communication interface between the operating system and the hardware device, enabling the operating system to identify, control and manage the functions of the hardware device.

[0068] In some embodiments, when the positioning tag device is powered on, a boot program is started to load system firmware and drivers.

[0069] S202: Initialize the hardware module.

[0070] Among them, the hardware modules include device indicator lights, device buttons, inertial sensors, magnetic sensors, CPU, network bus, serial port, hardware operation monitoring manager, and 5G module.

[0071] In some embodiments, the device indicator light is used to provide feedback on whether the device is started normally; the device button is used for the device to interact with the user, and triggers the corresponding function by receiving the user's operation; the inertial sensor is used to sense the state change of the device and generate an interrupt signal; the magnetic sensor is used to sense the location information of the device; the CPU is used to execute program instructions; the network bus is used for the connection and communication between the CPU and the 5G module; the serial port is used for data exchange and communication between devices; the hardware operation monitoring manager is used to monitor the hardware operation status of the positioning tag device in real time, including CPU load, memory usage, temperature and other parameters; the 5G module is used to provide a higher transmission rate and communicate with remote servers and cloud platforms in real time and accurately.

[0072] In an embodiment of the present application, after the hardware module is initialized, the device indicator light turns on, the device buttons can respond to user input, the inertial sensor can sense changes in device status, the magnetic sensor can sense changes in the magnetic field, the CPU can execute instructions, the hardware operation monitoring manager can monitor the performance of the hardware device, and the 5G module can connect to the solution base station and transmit signals.

[0073] S203: Configure interrupt parameters of the inertial sensor.

[0074] Among them, the interrupt parameters of the inertial sensor include sensitivity, threshold and interrupt priority.

[0075] In some embodiments, the sensitivity is used to reflect the sensitivity of the inertial sensor to the change in the state of the positioning tag device; the threshold is used to set the acceleration value that triggers the interrupt signal; and the interrupt priority is used to determine the order in which the interrupt request is processed.

[0076] Exemplarily, the high sensitivity of the inertial sensor means that the inertial sensor can accurately detect the state change of the positioning tag device. For example, if the positioning tag device is accidentally touched, the inertial sensor will still output a level signal.

[0077] Exemplarily, when the acceleration value detected by the inertial sensor exceeds a set threshold, an interrupt signal is generated and sent to the processor; when the acceleration value detected by the inertial sensor is less than or equal to the set threshold, no interrupt signal is generated.

[0078] Exemplarily, the interrupt priority of the inertial sensor is high, which means that when multiple interrupt requests arrive at the same time, the request that generates the interrupt signal will be processed first.

[0079] S204, start the positioning tag device software program.

[0080] Among them, the positioning tag device software program includes the positioning system process, user event processing program, low power management system and anti-violent demolition business program.

[0081] In some embodiments, the positioning system process is used to monitor the location information of the positioning tag device, ensure the real-time and accuracy of the data, and transmit the data to the server; the user event handler is used to handle events related to user interaction, detect user operations or button status on the positioning tag device; the low power management system is used to adjust the sleep strategy according to preset conditions to achieve the best energy-saving effect; the anti-violent demolition business program is used to trigger an alarm signal when the positioning tag device is damaged, and send the alarm signal to the base station server.

[0082] like Figure 3 As shown, it is a flow chart of a method for energy saving of a positioning tag device provided by an embodiment of the present application. The method may include the following S301 to S303:

[0083] S301: Obtain the interrupt frequency of the positioning tag device.

[0084] Among them, the interruption frequency is used to characterize the motion state of the positioning tag device. Within the preset time period, when the positioning tag device is in a fast motion state, the inertial sensor triggers more interruption signals and the interruption frequency is high; when the positioning tag device is in a slow motion state, the inertial sensor triggers fewer interruption signals and the interruption frequency is low.

[0085] In some embodiments, the positioning tag device reads the number of interruptions and the window duration to calculate the interruption frequency per unit time, wherein the window duration represents the time length of a motion cycle.

[0086] Exemplary, combined Figure 1 When an interrupt occurs in the inertial sensor 101, the interrupt handler starts the interrupt processing task. The interrupt processing task reads the real-time data of the inertial sensor 101, processes the position information and reports the data. The interrupt processing task records the number of interrupts triggered by the inertial sensor 101 within the window duration, and the positioning tag device reads the number of interrupts and the window duration, and calculates the interrupt frequency per unit time.

[0087] Exemplarily, when the window duration is 1 second, and the number of interruptions recorded by the interrupt processing task is 10 times, the interruption frequency is 10 times / second.

[0088] S302: Determine a target sleep level of the positioning tag device among multiple sleep levels based on the interruption frequency.

[0089] The sleep level is used to determine the sleep strategy.

[0090] In some embodiments, the multiple sleep levels of the positioning tag device include a first sleep level, a second sleep level, a third sleep level, and a fourth sleep level. Among the four sleep levels, the first sleep level has the shortest wake-up delay, which can ensure that the positioning tag device enters the working state in the shortest time; the second sleep level has a shorter wake-up delay, which can ensure fast wake-up with low power consumption; the third sleep level has a moderate wake-up delay, which can ensure responsiveness with low power consumption when it is in a static state for a long time and does not need to frequently update the location information; the fourth sleep level has the longest wake-up delay, and the power consumption of the positioning tag device is extremely low when it is in a static state for a long time, but the time to wake up to the normal working state is also the longest.

[0091] Of course, the above four sleep levels are only examples. In actual applications, the number of sleep levels can be set according to actual needs, and the corresponding sleep strategy can be re-determined based on the number of sleep levels.

[0092] In an optional implementation, when the interruption frequency is less than a first threshold and greater than or equal to a second threshold, the first sleep level is determined as a target sleep level of the positioning tag device;

[0093] When the interruption frequency is less than the second threshold and greater than or equal to the third threshold, the second sleep level is determined as the target sleep level of the positioning tag device;

[0094] When the interruption frequency is less than the third threshold and greater than or equal to the fourth threshold, the third sleep level is determined as the target sleep level of the positioning tag device;

[0095] When the interruption frequency is less than the fourth threshold and greater than or equal to the fifth threshold, the fourth sleep level is determined as the target sleep level of the positioning tag device.

[0096] Exemplarily, when the interruption frequency is 35, the first threshold is 40, and the second threshold is 30, the target sleep level of the positioning tag device is the first sleep level;

[0097] When the interruption frequency is 25, the second threshold is 30, and the third threshold is 20, the target sleep level of the positioning tag device is the second sleep level;

[0098] When the interrupt frequency is 15, the third threshold is 20, and the fourth threshold is 10, the target sleep level of the positioning tag device is the third sleep level;

[0099] When the interrupt frequency is 5, the fourth threshold is 10, and the fourth threshold is 0, the target sleep level of the positioning tag device is the fourth sleep level.

[0100] In this way, the sleep level of the positioning tag device is dynamically adjusted through the state changes of the device. When the interrupt frequency is high, the sleep level is lowered so that the positioning tag device can meet the needs of high-precision and real-time positioning; when the interrupt frequency is low, the sleep level is increased to reduce the active time of the positioning tag device, thereby reducing energy consumption.

[0101] S303: Execute a sleep strategy corresponding to the target sleep level.

[0102] Among them, different target sleep levels implement different sleep strategies, and different sleep strategies have different energy-saving effects.

[0103] In an optional implementation, the sleep strategy corresponding to the first sleep level includes at least one of the following: turning off the device indicator light, turning off the scanning and response functions of the device buttons, turning off the magnetic sensor, turning off idle processes and services, turning on periodic heartbeat detection, turning on local storage of fingerprint crowdsourcing data, monitoring the static time, and turning on anti-violent demolition.

[0104] It is understandable that turning off the device indicator light, turning off the scanning and response function of the device button, turning off the magnetic sensor, and turning off idle processes and services are all used to reduce power consumption. Among them, turning off the scanning and response function of the device button includes: disabling the button interrupt service, stopping the polling and response of the button status; turning off idle processes and services, and identifying and turning off currently idle and positioning-independent processes and services by executing the task manager. Idle processes and services include: log management, temperature control strategy, system abnormality monitoring, network status monitoring, voice wake-up, and SMS services.

[0105] Turn on the periodic heartbeat detection, set the timer through the positioning interrupt, trigger the detection regularly, send the heartbeat packet to the positioning platform cloud server, and store the collected fingerprint crowdsourcing data in the terminal. When the device is restored from the first sleep level to the normal working mode, the periodic heartbeat detection function is turned off, and the fingerprint crowdsourcing data stored in the terminal is uploaded to the positioning platform cloud server, avoiding the energy waste caused by real-time data transmission. Among them, the heartbeat packet contains the device ID and the current status information of the device, such as the battery power.

[0106] The monitoring of the inactivity time is used to automatically adjust the sleep level according to the comparison between the inactivity time of the positioning tag device and the preset time.

[0107] Enable anti-violent removal to prevent the location tag device from being damaged and improve physical security.

[0108] Optionally, the indicator light can be turned off by sending a signal through a general purpose input / output port (GPIO); the periodic heartbeat detection trigger time can be set to 1 minute.

[0109] In another optional implementation, the sleep strategy corresponding to the second sleep level includes at least one of the following: turning off the device indicator light, turning off the scanning and response functions of the device buttons, turning off the magnetic sensor, turning off idle processes and services, increasing the periodic heartbeat detection trigger time, turning off the storage of fingerprint crowdsourcing data, monitoring the static time, turning on anti-violent demolition, reducing the SRS signal frequency, reducing the CPU operating frequency of the positioning tag device, turning off the network kernel subsystem, turning off the network interface, and turning off serial port communication.

[0110] It is understandable that turning off device indicator lights, turning off the scanning and response functions of device buttons, turning off magnetic sensors, and turning off idle processes and services are all used to reduce power consumption.

[0111] Increase the trigger time of regular heartbeat detection, turn off the storage of fingerprint crowdsourcing data, reduce the SRS signal frequency, reduce the CPU operating frequency of the positioning tag device, turn off the network kernel subsystem, turn off the network interface, and turn off serial port communication to reduce the power consumption generated by the positioning tag device.

[0112] Among them, the SRS frequency is lowered by adjusting the system clock frequency register to reduce the number of signal transmissions; the CPU operating frequency of the positioning tag device is reduced to reduce the computing power of the processor; the network kernel subsystem is shut down, the network interface is shut down, all network-related services and communications are stopped, and the power consumption generated by the network module is reduced; the serial port communication is shut down, and the interrupts and communications related to the serial port are disabled.

[0113] The monitoring of the inactivity time is used to automatically adjust the sleep level according to the comparison between the inactivity time of the positioning tag device and the preset time.

[0114] Enable anti-violent removal to prevent the location tag device from being damaged and improve physical security.

[0115] Optionally, the SRS signal frequency can be reduced to 5 seconds; the CPU operating frequency can be reduced to the lowest frequency allowed by its model; the serial port includes but is not limited to a universal asynchronous receiver / transmitter (UART); and the periodic heartbeat detection trigger time can be set to 2 minutes.

[0116] In another optional implementation, the sleep strategy corresponding to the third sleep level includes at least one of the following: turning off the device indicator light, turning off the scanning and response functions of the device buttons, turning off the magnetic sensor, turning off idle processes and services, turning off heartbeat detection, turning off storage of fingerprint crowdsourcing data, monitoring the static time, turning on anti-violent demolition, reducing the SRS signal frequency, reducing the CPU operating frequency of the positioning tag device, turning off the network kernel subsystem, turning off the network interface, turning off serial port communication, putting the communication module into sleep mode, and retaining the hardware operation monitoring manager function.

[0117] It is understandable that turning off device indicator lights, turning off the scanning and response functions of device buttons, turning off magnetic sensors, and turning off idle processes and services are all used to reduce power consumption.

[0118] Turn off heartbeat detection, turn off storage of fingerprint crowdsourcing data, reduce SRS signal frequency, reduce the CPU operating frequency of the positioning tag device, turn off the network kernel subsystem, turn off the network interface, and turn off serial port communication to reduce the power consumption generated by the positioning tag device.

[0119] Put the communication module into sleep mode and send a sleep command to the communication module through AT command to stop communication activities and keep key components in working state to ensure that the communication module can resume communication state as needed.

[0120] The hardware operation monitoring manager function is retained to monitor the hardware operation status of the positioning tag device.

[0121] The monitoring of the inactivity time is used to automatically adjust the sleep level according to the comparison between the inactivity time of the positioning tag device and the preset time.

[0122] Enable anti-violent removal to prevent the location tag device from being damaged and improve physical security.

[0123] Optionally, key components include but are not limited to CPU timers.

[0124] Optionally, when the inactivity time is reduced and the preset threshold of the second sleep level is met, the sleep level is reduced from the third sleep level to the second sleep level, and the sleep strategy corresponding to the second sleep level is executed: turn off the device indicator light, turn off the scanning and response functions of the device buttons, turn off the magnetic sensor, turn off idle processes and services, increase the periodic heartbeat detection trigger time, turn off the storage of fingerprint crowdsourcing data, monitor the inactivity time, turn on anti-violent demolition, reduce the SRS signal frequency, reduce the CPU operating frequency of the positioning tag device, turn off the network kernel subsystem, turn off the network interface, and turn off serial port communication.

[0125] Optionally, when the inactivity time continues to decrease and meets the preset threshold of the first sleep level, after the sleep level is reduced from the third sleep level to the second sleep level, it continues to be reduced to the first sleep level, and the sleep policy corresponding to the first sleep level is executed: turn off the device indicator light, turn off the scanning and response functions of the device buttons, turn off the magnetic sensor, turn off idle processes and services, turn on periodic heartbeat detection, turn on local storage of fingerprint crowdsourcing data, monitor the inactivity time, and turn on anti-violent demolition.

[0126] Optionally, when the inactivity time continues to increase and meets a preset threshold of the fourth sleep level, the sleep level is increased from the third sleep level to the fourth sleep level.

[0127] In another optional implementation, the sleep strategy corresponding to the fourth sleep level includes at least one of the following: turning off the device indicator light, turning off the scanning and response functions of the device buttons, turning off the magnetic sensor, turning off idle processes and services, turning off heartbeat detection, turning off storage of fingerprint crowdsourcing data, monitoring the static time, turning on anti-violent demolition, reducing the SRS signal frequency, reducing the CPU operating frequency of the positioning tag device, turning off the network kernel subsystem, turning off the network interface, turning off serial port communication, turning off peripheral power, retaining the CPU core voltage, voltage-sensitive switch power supply and system clock module power supply, and configuring the alarm wake-up source.

[0128] It is understandable that the fourth sleep level means that the positioning tag device is in a sleep state for a long time. Turning off the device indicator light, turning off the scanning and response functions of the device buttons, turning off the magnetic sensor, turning off idle processes and services, and turning off the power of peripherals are all used to reduce power consumption.

[0129] Turn off heartbeat detection, turn off storage of fingerprint crowdsourcing data, reduce SRS signal frequency, reduce the CPU operating frequency of the positioning tag device, turn off the network kernel subsystem, turn off the network interface, and turn off serial port communication to reduce the power consumption generated by the positioning tag device.

[0130] The CPU core voltage, voltage-sensitive switch power supply, and system clock module power supply are retained to minimize the power consumption of the positioning tag device.

[0131] Monitor the inactivity time to automatically adjust the sleep level based on the comparison between the inactivity time of the positioning tag device and the preset time.

[0132] Enable anti-violent removal to prevent the location tag device from being damaged and improve physical security.

[0133] Configure the alarm wake-up source to automatically wake up the CPU, ensure that the positioning tag device maintains communication with the cloud server through the system clock trigger mechanism in the fourth sleep level, and reports status information in time to monitor abnormal stillness and trigger processing measures.

[0134] In some embodiments, when the positioning tag device is forcibly removed, the pressure-sensitive switch is used to generate a level signal to wake up the CPU, the positioning tag device enters the working state, turns on the vibration alarm, and sends the event to the base station server.

[0135] In some embodiments, when the system clock reaches a preset alarm wake-up time, the system clock generates a level signal to wake up the CPU, the CPU sends the event to the positioning platform cloud server, and configures the next alarm wake-up source; when the positioning platform cloud server accumulates a preset number of alarm wake-up events, it indicates that the positioning tag device is in an idle state, the positioning platform cloud server updates the status of the positioning tag device, and further processes it according to the business logic, such as completely shutting down or starting an sound and light alarm to assist in finding the lost positioning tag device.

[0136] Optionally, the alarm wake-up time can be set to 12 hours.

[0137] In this way, by executing corresponding sleep strategies through different sleep levels, the sleep strategy can be flexibly adjusted according to the actual state of the positioning tag device, the balance between power consumption and response speed can be controlled, and the optimal energy saving effect can be achieved when the response speed meets the requirements.

[0138] For example, Figure 4 As shown, it is a system function diagram of a positioning tag device provided in an embodiment of the present application, including a communication module, other modules and a positioning service. The system function diagram represents the functions executed corresponding to different sleep strategies.

[0139] Among them, the communication module and other modules are used to load system firmware and drivers and initialize hardware modules; the positioning service is used to configure the sleep level switching threshold.

[0140] In some embodiments, when the positioning tag device changes from a normal working state to a first sleep level, the sleep strategy executed includes: the communication module turns off voice calls and SMS services; other modules turn off indicator lights, button scanning and responses, magnetic sensors, and idle processes and services; the positioning service turns on local storage of fingerprint crowdsourcing, turns on regular heartbeat detection, monitors the length of time that remains stationary, and turns on anti-violent demolition.

[0141] In some embodiments, when the positioning tag device changes from a first sleep level to a second sleep level, the sleep strategies executed include: the communication module shuts down voice calls and SMS services, reduces SRS frequency, reduces CPU frequency, and shuts down the underlying network protocol stack; other modules shut down indicator lights, button scanning and responses, magnetic sensors, idle processes and services, and serial port communications; the positioning service shuts down local storage of fingerprint crowdsourcing, turns on periodic heartbeat detection, monitors the length of time that remains stationary, and turns on anti-violent demolition.

[0142] In some embodiments, when the positioning tag device changes from the second sleep level to the third sleep level, the sleep strategies executed include: sleeping the communication module; other modules turn off indicator lights, turn off button scanning and response, turn off magnetic sensors, turn off idle processes and services, turn off serial port communications, and retain hardware operation monitoring; business positioning turns off local storage fingerprint crowdsourcing, turns off periodic heartbeat detection, monitors the length of time that is idle, and turns on anti-violent demolition.

[0143] In some embodiments, when the positioning tag device goes from the third sleep level to the fourth sleep level, the sleep strategies executed include: the communication module sleeps the CPU; other modules turn off indicator lights, turn off button scanning and response, turn off magnetic sensors, turn off idle processes and services, turn off serial port communications, retain the system clock, and retain the pressure-sensitive switch; business positioning turns off local storage fingerprint crowdsourcing, turns off periodic heartbeat detection, monitors the length of time that is idle, and turns on anti-violent demolition.

[0144] In the energy-saving method for the positioning tag device provided in the embodiment of the present application, the energy consumption of the positioning tag device is wasted due to the inflexible energy consumption management mechanism of the positioning tag device. Therefore, the present application obtains the interruption frequency of the positioning tag device to obtain the movement state of the positioning tag device, and determines multiple sleep levels in combination with the state changes of the positioning tag device, thereby executing corresponding sleep strategies. Different sleep levels correspond to different sleep strategies, thereby achieving accuracy and flexibility in power consumption management of the positioning tag device.
