Technical Field

[0001] The present invention relates to the field of communication technologies, and particularly to a GPS system with intelligent sleep and wake-up functions and a switching method thereof. Background Art

[0002] Since the advent of the Global Positioning System (GPS), with its advantages of high precision, all-weather, and global positioning, it has been widely used in many fields. With the wide application of GPS positioning devices in personal, vehicle, and asset management, how to effectively reduce the power consumption of GPS devices has become an urgent problem to be solved. Especially in small devices and long-endurance scenarios, the power consumption of GPS devices directly affects the user experience and the service life of the devices.

[0003] Traditional GPS systems need to continuously receive and process satellite signals during operation, which results in relatively high power consumption. Taking a common portable GPS device as an example, due to the limited battery capacity, the continuous high power consumption makes the device have a short battery life, and users need to frequently charge, which brings great inconvenience to use. In some special application scenarios, such as long-term field monitoring and pet tracking, frequent charging is difficult to achieve, which limits the usage duration and scope of GPS devices. Summary of the Invention

[0004] The present invention provides a GPS system with intelligent sleep and wake-up functions and a switching method thereof to solve the problems of short battery life and frequent charging in the prior art.

[0005] To achieve the above object, on the one hand, an embodiment of the present invention provides a GPS system with intelligent sleep and wake-up functions. The GPS system includes: a GPS positioning module, a monitoring module, a control terminal, and a switching module. After the GPS system is started through the control terminal, the monitoring module detects the status information of the terminal device, and the switching module switches the operating mode of the GPS positioning module according to the status information of the terminal device. The status information includes the movement speed and vibration information, and the operating mode includes a sleep mode and a working mode.

[0006] Optionally, the GPS positioning module includes: a radio frequency front end for receiving GPS satellite signals; a baseband processing unit for processing the received GPS satellite signals and extracting corresponding positioning information.

[0007] Optionally, the monitoring module includes: a speed detection module for detecting the moving speed of the terminal device; a vibration detection module for detecting the vibration information of the terminal device.

[0008] Optionally, the switching module switches the operating mode of the GPS positioning module according to the status information of the terminal device, which includes: when the moving speed of the GPS positioning module does not exceed a set value, or the missing time of the vibration signal of the terminal device exceeds a first preset value, the switching module cuts off the internal power supply circuit of the GPS positioning module to make the GPS positioning module enter the sleep mode; when the vibration signal of the terminal device exists, the switching module connects the internal power supply circuit of the GPS positioning module to make the GPS positioning module enter the working mode.

[0009] Optionally, the GPS system further includes: a storage unit for storing the positioning information of the terminal device extracted by the baseband processing unit; a signal transmitting unit for transmitting the positioning information, moving speed, and vibration signal of the terminal device to the mobile terminal; and a mobile terminal for receiving the positioning information, moving speed, and vibration signal of the terminal device transmitted by the signal transmitting unit, and performing data processing and digital display.

[0010] Optionally, when the internal data of the storage unit exceeds the preset number of stored items, circular storage is adopted to improve the utilization rate of the storage space.

[0011] Optionally, the GPS system further includes: a self-power generation unit, which is installed inside the GPS positioning module. The self-power generation unit includes: an inductance coil, a high-magnetic-flux magnet installed inside the induction coil, a spring placed at both ends of the inductance coil, a rectification module, an electrical filtering module, a linear voltage regulator, and a lithium battery charging management module. When the GPS positioning module vibrates, it will cause the high-magnetic-flux magnet to move horizontally back and forth inside the inductance coil, generating an induced electromotive force and generating alternating current. The inductance coil converts the alternating current into direct current. The electrical filtering module smooths the direct current. The linear voltage regulator stabilizes the smoothed direct current. The lithium battery charging management module controls the processed direct current to charge the lithium battery inside the GPS positioning module.

[0012] On the other hand, the present invention also provides a method for switching the operating mode of a GPS system, which is applied to the switching module of the above GPS system. The switching method includes: after starting the GPS system and the GPS system enters the standby mode, when the speed detection module detects that the moving speed of the terminal device does not exceed a set value, or the vibration detection module detects that the missing time of the vibration signal of the terminal device exceeds a first preset value, controlling the GPS positioning module to enter the sleep mode; when the vibration detection module detects the vibration signal of the terminal device, controlling the GPS positioning module to enter the working mode.

[0013] Optionally, the switching method further includes: after the GPS positioning module enters the working mode, when the speed detection module detects that the moving speed of the terminal device exceeds a set value, controlling the GPS positioning module to maintain the working mode; when the speed detection module detects that the moving speed of the terminal device does not exceed the set value, or the vibration detection module detects that the absence time of the vibration signal of the terminal device exceeds a second preset value, controlling the GPS positioning module to enter the sleep mode after a preset time.

[0014] Optionally, when the GPS positioning module maintains the working mode, the storage unit stores the positioning information of the terminal device in real time, and the signal transmitting unit sends the positioning information, moving speed and vibration signal of the terminal device to the mobile terminal for digital display.

[0015] A GPS system with intelligent sleep and wake-up functions provided by the present invention intelligently switches the operating mode of the GPS positioning module according to the moving speed and vibration information of the terminal device. When the device is stationary or the vibration is insufficient, the module automatically enters the sleep mode and cuts off the power supply to reduce power consumption; when a vibration signal is detected, it resumes work, effectively extending the battery life and meeting the usage requirements of scenarios where it is difficult to charge frequently. The self-power generation unit uses the vibration of the device to convert mechanical energy into electrical energy, which is processed and used to charge the lithium battery. This reduces the dependence on external power sources, realizes the effective utilization of energy, and reduces the number of charging times. Description of the Drawings

[0021] The following will describe in detail the specific implementation manners of the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0022] It should be noted that the acquisition, transmission, storage, use, processing, etc. of data in the technical solution of this application all comply with the relevant regulations of national laws and regulations. In the embodiments of this application, some existing solutions in the industry such as certain software, components, models, etc. may be mentioned. They should be regarded as exemplary. The purpose is only to illustrate the feasibility in the implementation of the technical solution of this application, but it does not mean that the applicant has already or necessarily used this solution.

[0023] With the wide application of GPS positioning devices in personal, vehicle, and asset management, how to effectively reduce the power consumption of GPS devices has become an urgent problem to be solved. Especially in small devices and long-endurance scenarios, the power consumption of GPS devices directly affects the user experience and the service life of the devices. Therefore, it is particularly important to develop an efficient GPS power-saving mode.

[0024] To solve this problem, the present invention provides a GPS system with intelligent sleep and wake-up functions and its switching method. According to the movement speed and vibration condition of the terminal device, the GPS positioning module is intelligently switched between the working mode and the sleep mode, greatly extending the battery life of the device. At the same time, the built-in self-power generation unit cleverly utilizes the mechanical energy generated by the device vibration. Through the coordinated work of components such as inductance coils, high-magnetic-flux magnets, and springs, the vibration energy is converted into electrical energy. Subsequently, after a series of processes such as rectification, filtering, and voltage stabilization, this electrical energy is transmitted to the lithium battery for charging. This innovative design effectively reduces the system's dependence on external power sources, realizes the efficient utilization and replenishment of energy, and ensures that the system can operate continuously and stably in various complex environments.

[0025] The following will describe the present invention in combination with Figures 1-3 Specifically describe the present invention.

[0026] Embodiment 1:

[0027] As Figure 1 shown, the embodiment of the present invention provides a GPS system with intelligent sleep and wake-up functions. The GPS system includes: a GPS positioning module, a monitoring module, a control terminal, and a switching module. After the GPS system is started through the control terminal, the monitoring module detects the status information of the terminal device, and the switching module switches the operating mode of the GPS positioning module according to the status information of the terminal device. The status information includes the movement speed and vibration information, and the operating mode includes a sleep mode and a working mode.

[0028] Preferably, the GPS positioning module includes: a radio frequency front end for receiving GPS satellite signals; and a baseband processing unit for processing the received GPS satellite signals and extracting corresponding positioning information.

[0029] In a preferred embodiment of the present invention, when the power management unit controls the operation of the GPS positioning module, after the antenna in the GPS positioning module captures weak signals transmitted from multiple GPS satellites, it transmits them to the radio frequency front end. The radio frequency front end amplifies the signals to enhance the signal strength and performs a down-conversion operation to convert the high-frequency carrier signal into an intermediate-frequency signal. Subsequently, the intermediate-frequency signal enters the baseband processing unit, where through correlation operations, the received signal is matched with the local reference signal to determine the approximate carrier frequency and code phase of the satellite signal, and the positioning information of the terminal device is decoded from the signal, thus completing the positioning of the terminal device.

[0030] Preferably, the monitoring module includes: a speed detection module for detecting the moving speed of the terminal device; and a vibration detection module for detecting the vibration information of the terminal device.

[0031] In a preferred embodiment of the present invention, the moving speed and vibration information of the terminal device detected by the monitoring module provide a basis for judging the sleep state of the GPS system.

[0032] Preferably, the switching module switches the operating mode of the GPS positioning module according to the status information of the terminal device, including: when the moving speed of the GPS positioning module does not exceed a set value, or the absence time of the vibration signal of the terminal device exceeds a first preset value, the switching module cuts off the internal power supply circuit of the GPS positioning module to make the GPS positioning module enter the sleep mode; when the vibration signal of the terminal device exists, the switching module connects the internal power supply circuit of the GPS positioning module to make the GPS positioning module enter the working mode.

[0033] Preferably, the GPS system further includes: a storage unit for storing the positioning information of the terminal device extracted by the baseband processing unit; a signal transmitting unit for transmitting the positioning information, moving speed, and vibration signal of the terminal device to a mobile terminal; and a mobile terminal for receiving the positioning information, moving speed, and vibration signal of the terminal device transmitted by the signal transmitting unit and performing data processing and digital display.

[0034] In a preferred embodiment of the present invention, the GPS system stores the positioning information of the terminal device in the storage unit and transmits it to the mobile terminal through the signal transmitting unit. The mobile terminal can process and display various received data information, facilitating the user to master their own exercise state.

[0035] Preferably, when the internal data of the storage unit exceeds the preset number of stored items, cyclic storage is adopted to improve the utilization rate of the storage space.

[0036] In a preferred embodiment of the present invention, when the GPS system is working, it will continuously generate data such as positioning information, moving speed, and vibration signals, and these data need to be continuously recorded. Since the storage space of the storage unit is limited, if the traditional storage method is adopted, when the storage space is full, new data cannot be recorded continuously. The cyclic storage method allows the system to automatically overwrite the earliest stored data after the storage space reaches the upper limit, so as to continuously record new data and ensure that the system can run for a long time without manual intervention to clean the storage space.

[0037] As Figure 2 shown, the present invention also provides a method for switching the operating mode of a GPS system, which is applied to the switching module of the above GPS system. The switching method includes:

[0038] Step 101, after starting the GPS system and the GPS system enters the standby mode, when the speed detection module detects that the moving speed of the terminal device does not exceed the set value, or the vibration detection module detects that the vibration signal absence time of the terminal device exceeds the first preset value, control the GPS positioning module to enter the sleep mode;

[0039] Step 102, when the vibration detection module detects the vibration signal of the terminal device, control the GPS positioning module to enter the working mode.

[0040] Taking an example, as Figure 4 shown, the set value of the moving speed is, for example, 5 km / h, the first preset value is, for example, 10 minutes, and the current speed of the terminal device is 4 km / h. Then the current speed of the terminal device is less than the set value. At this time, the switching module will make the GPS positioning module enter the sleep mode to save power. Furthermore, when the vibration detection module does not detect the vibration information of the terminal device for more than 10 minutes, the GPS positioning module will also enter the sleep mode. After the GPS positioning module enters the sleep mode, if the vibration detection module detects the vibration signal of the terminal device, that is, when the terminal device starts to move, the switching module will control the GPS positioning module to enter the working mode to monitor the positioning of the terminal device.

[0041] As Figure 3 shown, the switching method further includes:

[0042] Step 201: After the GPS positioning module enters the working mode, when the speed detection module detects that the moving speed of the terminal device exceeds the set value, control the GPS positioning module to maintain the working mode;

[0043] Step 202: When the speed detection module detects that the moving speed of the terminal device does not exceed the set value, or the vibration detection module detects that the missing time of the vibration signal of the terminal device exceeds the second preset value, control the GPS positioning module to enter the sleep mode after a preset time.

[0044] Illustrated by way of example, as Figure 4 shown, the set value of the moving speed is, for example, 5 km / h, the second preset value is, for example, 5 minutes, and the preset time is, for example, 30 seconds. After the GPS positioning module enters the working mode, if the moving speed of the terminal device exceeds 5 km / h (for example, 6 km / h), the state of the GPS positioning module is maintained. If the moving speed of the terminal device is less than 5 km / h (for example, 4 km / h), or the missing time of the vibration information of the terminal device exceeds 5 minutes, the switching module will control the GPS positioning module to enter the sleep mode after 30 seconds.

[0045] Preferably, when the GPS positioning module maintains the working mode, the storage unit stores the positioning information of the terminal device in real time, and the signal transmitting unit sends the positioning information, moving speed and vibration signal of the terminal device to the mobile terminal for digital display.

[0046] More preferably, the control terminal is further configured to: adjust the set value, the first preset value, the second preset value, and the number of storage items of the storage unit.

[0047] In a preferred embodiment of the present invention, by controlling the control terminal to adjust the condition parameters for switching the operation mode of the GPS positioning module, the system can better adapt to different usage environments, ensure that the system accurately judges the vibration state of the device, stably switch the operation mode of the positioning module, and reduce the probability of misoperation and faults.

[0048] A GPS system with intelligent sleep and wake-up functions provided by an embodiment of the present invention intelligently switches the operation mode of the GPS positioning module according to the movement speed and vibration information of the terminal device. When the device is stationary or the vibration is insufficient, the module automatically enters the sleep mode to cut off the power supply to reduce power consumption; when a vibration signal is detected, it resumes work, effectively extending the battery life and meeting the usage requirements of scenarios where it is difficult to charge frequently.

[0049] Embodiment 2:

[0050] To reduce the charging frequency of the GPS system, the GPS system provided by the embodiments of the present invention further includes: a self-power generation unit, the self-power generation unit is installed inside the GPS positioning module, and the self-power generation unit includes: an inductance coil, a high-magnetic-flux magnet installed inside the induction coil, springs placed at both ends of the inductance coil, a rectification module, an electrical filtering module, a linear voltage regulator, and a lithium battery charging management module. When the GPS positioning module vibrates, the high-magnetic-flux magnet will move horizontally back and forth inside the inductance coil, generating an induced electromotive force and generating alternating current. The inductance coil converts the alternating current into direct current. The electrical filtering module smooths the direct current. The linear voltage regulator stabilizes the smoothed direct current. The lithium battery charging management module controls the processed direct current to charge the lithium battery inside the GPS positioning module.

[0051] Taking an example, when a pet wears the GPS system provided by the present invention, the vibration generated by the pet running will cause the high-magnetic-flux magnet to move horizontally back and forth inside the inductance coil. The movement of the high-magnetic-flux magnet will cut the magnetic field lines, generating an induced electromotive force inside the inductance coil, and then generating alternating current. The generated alternating current is rectified by the rectification module and converted into direct current. Subsequently, the filtering module smooths the direct current to remove voltage ripples. Then, it passes through the linear voltage stabilization module to ensure that the output voltage is stable and has a smooth transition. Finally, the lithium battery charging management module distributes the electric energy to charge the lithium battery inside the GPS positioning module, thus realizing self-charging, greatly extending the usage time of the GPS device, significantly reducing the charging frequency, and improving the user experience. At the same time, the charging management module can provide overcharge protection and current limiting functions, extending the life of the lithium battery.

[0052] The GPS system with intelligent sleep and wake-up functions provided by the embodiments of the present invention cleverly utilizes the mechanical energy generated by the vibration of the device. Through the coordinated work of components such as the inductance coil, high-magnetic-flux magnet, and spring, the vibration energy is converted into electrical energy. Subsequently, after a series of processes such as rectification, filtering, and voltage stabilization, this electrical energy is transmitted to the lithium battery for charging. This innovative design effectively reduces the system's dependence on external power sources, realizes the efficient utilization and replenishment of energy, and ensures that the system can operate continuously and stably in various complex environments.

[0053] Embodiment Three:

[0054] To enhance the positioning accuracy and fault detection ability of the GPS system, a carrier phase tracking algorithm is incorporated into the GPS system provided in the embodiments of the present invention. A carrier phase tracking sub-module and a carrier phase monitoring sub-module are provided. The carrier phase tracking sub-module is arranged inside the baseband processing unit and is responsible for realizing the functions of carrier phase acquisition, tracking, and measurement. The carrier phase monitoring sub-module is used to monitor the state and related parameters of carrier phase tracking in real time and provide data support for fault detection.

[0055] After the GPS system is started, the RF front end receives the satellite signal and transmits it to the baseband processing unit. The carrier phase tracking sub-module first performs signal acquisition operations. Using a method based on correlation operation, the received signal is correlated with the locally generated reference signal. The correlation function R(τ) is:

[0056]

[0057] where s(t) is the received signal and c(t) is the local reference signal. By searching for different carrier frequencies and code phases, the parameters that make the correlation function R(τ) reach the peak are found, thereby determining the approximate carrier frequency and code phase of the satellite signal. Subsequently, the phase-locked loop technology is used for carrier phase tracking. During the tracking process, the phase change of the local voltage-controlled oscillator is recorded to obtain the carrier phase measurement value of the GPS signal. Subsequently, the carrier phase monitoring sub-module monitors the carrier phase change rate in real time. The formula is:

[0058]

[0059] where t i represents time. By comparing the monitored carrier phase change rate with the normal range of the preset carrier phase change rate, it can be determined whether the GPS system has a fault.

[0060] For example, the normal range of the preset carrier phase change rate is 0 Hz to 50 Hz per second, and the monitored carrier phase change rate is 60 Hz. Then, at this time, the GPS system has a fault and prompts the user to make adjustments.

[0061] In addition, when the GPS system enters the working mode, the carrier phase tracking algorithm starts to work normally, tracking and monitoring the carrier phase in real time. When the GPS system enters the sleep mode, to reduce power consumption, some functions of the carrier phase tracking algorithm are suspended, which, combined with the switching method of the operating mode of the GPS system provided by the present invention, reduces the energy consumption.

[0062] In the embodiments of the present invention, by successfully integrating the carrier phase tracking algorithm into the GPS system, the positioning accuracy and fault detection ability of the GPS system are enhanced.

[0063] In summary, a GPS system with intelligent sleep and wake-up functions and its switching method provided by the present invention have two innovative points: intelligent mode switching and self-power generation technology, effectively reducing the operating power consumption and realizing energy replenishment. It can intelligently switch the working mode and sleep mode of the GPS positioning module according to the movement speed and vibration condition of the terminal device. When the device is stationary or the vibration does not meet the preset conditions, the module automatically enters the sleep mode, cutting off the internal power supply circuit to avoid unnecessary power consumption; once a vibration signal meeting the conditions is detected, it quickly wakes up and resumes work, greatly extending the battery life of the device, especially suitable for application scenarios where it is difficult to charge frequently. At the same time, the system is built-in with a self-power generation unit, which cleverly uses components such as inductance coils, high-magnetic-flux magnets, and springs to convert the mechanical energy generated by the device's vibration into electrical energy, and then after rectification, filtering, and voltage stabilization, it is transmitted to the lithium battery for charging, effectively reducing the dependence on external power sources, realizing the efficient utilization and replenishment of energy, ensuring that the system can operate continuously and stably in various complex environments, and at the same time integrating the carrier phase tracking algorithm, having the fault detection ability.
