Description

Technical Field

[0001] The present invention relates to the field of communication and positioning technology, and in particular to an optimized near-field and far-field positioning mode switching method. Background Art

[0002] At present, China's society is gradually entering an aging society, and the problem of elderly care is becoming more and more serious. It is common for elderly people with dementia to get lost at home or on the way home from nursing homes. How to solve the problem of elderly people with dementia getting lost at home without anyone to take care of them is a major problem that needs to be solved in today's society. Similarly, the current lack of educational resources has caused great difficulties in school management, especially for the management of young children in kindergartens and primary schools. Because these children's self-management awareness is not yet sound, students often run around and teachers are unable to take care of them. Once a safety problem occurs, it will have a major impact on the school and the family; outside of school, on the way home, the "vacuum zone" where the school and parents cannot supervise will also have many problems, among which the problem of infringement on teenagers is more prominent. Accidental injuries and potential dangers exist everywhere for primary and secondary school students, and vicious incidents occur from time to time. In order to solve the above problems, the positioning devices for the elderly and students in school mainly include locators, positioning bracelets, phone watches, etc. These positioning devices are basically based on satellite positioning technology + mobile communication technology or based on Bluetooth positioning technology + WIFI technology. Based on satellite positioning technology + mobile communication technology, the location information received by the satellite is transmitted to the guardian's mobile phone APP through the public network, so as to achieve the purpose of locating the elderly and students. Another method based on Bluetooth positioning technology + WIFI technology is to install Bluetooth positioning beacons in nursing homes and campuses to draw a "map" of the nursing home or school. The elderly and students wear positioning devices such as positioning bracelets. The elderly and students can accurately locate their locations through beacons at any location in the nursing home or school. The positioning information is transmitted to the positioning platform on campus through the WIFI network deployed in the campus, so as to achieve accurate information on the location of the elderly and students.

[0003] In the prior art, regarding the technical solutions for implementing different positioning switching, CN201510273112 uses a complex model to confirm the switching rules, and CN201410802103 continuously searches for Bluetooth signals and only starts switching after the Bluetooth signals are found. None of them can solve the problem of intelligently switching positioning modes according to scenarios. Summary of the invention

[0004] Therefore, it is necessary to provide a new specific application method for switching between far-field positioning and near-field positioning;

[0005] To achieve the above-mentioned purpose, the inventor provides a multi-positioning switching management method, comprising the following steps: detecting the wearing status information of the first component, detecting whether the second component is within the range of the near-field positioning signal, and making the following judgment: if it is detected that the wearing status of the first component is worn, the second component switches to the far-field positioning mode; if the wearing status of the first component is not worn and the second component is within the range of the near-field positioning signal, the second component switches to the near-field positioning mode.

[0006] Specifically, when the second component switches to the near-field positioning mode, it scans for nearby near-field positioning signals and forms a network with them.

[0007] Preferably, the second component is a wearable electronic device.

[0008] Specifically, the first component is a pressure sensing switch or a human body sensing switch.

[0009] A multi-positioning switching management system includes a first component and a second component.

[0010] The first component is used to send wearing status information according to its own wearing status, and the second component is used to detect near-field positioning signals and also to receive the wearing status information sent by the first component;

[0011] The second component is also used to switch to the far-field positioning mode when the wearing status information sent by the first component is received as being worn, and to switch to the near-field positioning mode when the wearing status information sent by the first component is received as not worn and the second component is within the range of the near-field positioning signal.

[0012] Specifically, the second component is specifically used to scan nearby near-field positioning signals and form a network with them when switching to the near-field positioning mode.

[0013] Specifically, the second component is a wearable electronic device.

[0014] Specifically, the first component is a pressure sensing switch or a human body sensing switch.

[0015] A wearing state sensor comprises a pressure-touch switch and a first signal sending unit, wherein the pressure-touch switch is used to enable the first signal sending unit when sensing pressure, the first signal sending unit is wirelessly connected to a second component, and the first signal sending unit sends a first signal to the second component after being enabled, and the second component comprises a network receiving unit, a Bluetooth positioning unit, a WIFi positioning unit, or a LoRa positioning unit; the network receiving unit is enabled to be connected with the Bluetooth positioning unit, the WIFi positioning unit, or the LoRa positioning unit, and the network receiving unit enables the Bluetooth positioning unit, the WIFi positioning unit, or the LoRa positioning unit after receiving the first signal.

[0016] Furthermore, the sensor further comprises a fixing portion, and the fixing portion is a pin, a clip or a buckle.

[0017] Through the above scheme, the technical effect of switching between the far-field positioning mode and the near-field positioning mode by the second component can be achieved only when the first component is worn, thereby avoiding the high power consumption problem caused by the second component continuously and actively scanning the near-field positioning signal, and also solving the problem of unstable signal when away from the near-field positioning signal.

[0027] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0028] This article will introduce a multi-positioning switching management method, including the following steps: S100 detects the wearing state information of the first component, S102 detects whether the second component is within the range of the near-field positioning signal, and makes the following judgment: S104 If the wearing state of the first component is detected as being worn, the second component switches to the far-field positioning mode, if the wearing state of the first component is not worn, and the second component is within the range of the near-field positioning signal, the second component switches to the near-field positioning mode. The wearing state information of the first component is the information worn on the biological body, which can be achieved by detecting biological signals, or by pressure sensing switches or human body sensing switches, infrared sensing switches, etc. The near-field positioning signal here refers to the short-range communication signal with an effective distance of about 10 meters to tens of meters in the prior art, such as Bluetooth, WIFi or LoRa communication mode, etc. The principle of using these signals to achieve positioning will not be repeated in this scheme. Corresponding to the near-field positioning signal, the far-field positioning signal referred to in this article refers to a signal that can be used for positioning with an effective range of hundreds of meters or thousands of meters, such as 3G, 4G, 5G communication signals, Beidou, GPS navigation signals, etc. In this embodiment, from a practical point of view, the near-field positioning signal can only be fixed in limited occasions, such as indoor environments such as schools and homes. When the user applies this method, he only needs to carry the first component when leaving the near-field positioning signal. The second component switches the positioning mode only after detecting the wearing state of the first component. The second component is preferably a commonly worn electronic device such as a children's watch, an elderly phone, and the like. The first component can be combined with items that are necessary to carry when going out and are often put down in indoor environments, such as school bags, briefcases, key chains, coats, and the like. When carrying the first component, switch to the outdoor (far-field) positioning mode, and switch back when putting down the first component. During this period, the two positioning modules can alternately enter sleep mode without the need to continuously search for signals, thereby achieving a good technical effect of reducing power consumption.

[0029] In a specific embodiment, when the second component switches to the near field positioning mode, the near field communication module will be awakened from sleep, scan the nearby near field positioning signal, and form a network with it. By putting the near field communication module to sleep, waking it up and scanning for networking, the technical effect of reducing power consumption can be achieved.

[0030] In some other embodiments, it is worth mentioning that the method can be implemented by directly communicating the first component with the second component, and the processor of the second component receives the signal of the first component, wakes up its dormant communication module, and searches for the signal. Alternatively, the processor can be provided by a third device in each indoor scene, and the third device is connected to the first component and the second component respectively, and then the judgment step S104 is performed by the third device in each indoor scene. The technical effect of reducing the power consumption of the second component can also be achieved, thereby reducing the overall energy consumption. At the same time, by providing third-party devices to form a centralized processing mode, it can also meet the expansion needs of more modules, such as redeploying RFID modules in each indoor scene to assist in judgment, etc.

[0031] exist Figure 2 In the embodiment shown, a multi-positioning switching management system will also be introduced, including a first component 10 and a second component 20, wherein the first component is used to send wearing status information according to its own wearing status, the second component is used to detect the near-field positioning signal, and is also used to receive the wearing status information sent by the first component; the second component is also used to switch to the far-field positioning mode when the wearing status information sent by the first component is received as being worn, and switch to the near-field positioning mode when the wearing status information sent by the first component is received as being not worn and the second component is within the range of the near-field positioning signal. The specific implementation method can be connected to the network of the first component and the second component, and the near-field positioning module circuit and the far-field positioning module circuit built into the second component can be turned on or off according to the wearing status signal. In some other specific embodiments, the second component is specifically used to scan the nearby near-field positioning signal when switching to the near-field positioning mode, and network with it. When applying this method, the user only needs to carry the first component when leaving the near-field positioning signal, and detect the wearing status of the first component, and the second component switches the positioning mode. The second component is preferably a commonly worn electronic device such as a children's watch, an elderly phone, etc. The first component can be combined with items that are necessary to carry when going out and often put down in indoor environments, such as school bags, briefcases, key chains, coats, etc. When carrying the first component, switch to outdoor (far-field) positioning mode, and switch back when putting down the first component. During this period, the two positioning modules can alternately enter sleep mode, without the need to constantly search for signals, achieving a good technical effect of reducing power consumption.

[0032] In some other further embodiments, the multi-positioning switching management system may also include a processor set in an indoor scene, and the processor is provided by a third device in each indoor scene, and the processor of the third device is respectively connected to the first component and the second component, and then the third device in each indoor scene performs the judgment step S104. The technical effect of reducing the power consumption of the second component can also be achieved, thereby reducing the overall energy consumption. At the same time, by providing third-party devices to form a centralized processing mode, it can also meet the expansion needs of more modules. For example, the multi-positioning switching system can also redeploy RFID modules in each indoor scene to assist in judgment, etc.

[0033] exist Figure 3 In the illustrated embodiment, we provide an application example of a first component, such as a wearable state sensor, including a pressure touch switch 1 and a first signal sending unit, wherein the pressure touch switch is used to enable the first signal sending unit when sensing pressure, such as the Bluetooth chip shown in the figure, the first signal sending unit is wirelessly connected to the second component, and the first signal sending unit sends a first signal to the second component after being enabled, and the second component includes a network receiving unit, a Bluetooth positioning unit or a WIFi positioning unit or a LoRa positioning unit; the network receiving unit is enabled to be connected with the Bluetooth positioning unit or the WIFi positioning unit or the LoRa positioning unit, and the network receiving unit enables the Bluetooth positioning unit or the WIFi positioning unit or the LoRa positioning unit after receiving the first signal.

[0034] In a further embodiment, we can see an example of the appearance of the wearable state sensor, the sensor also includes a fixing part 2, the fixing part is a pin, a clip or a buckle. Similarly, we take the campus student positioning scenario as an example, and other similar scenarios are not described one by one.

[0035] The student goes to school with a backpack at home, puts on the positioning terminal and clips the backpack clip switch on the backpack strap. The push switch of the backpack clip switch is pressed by the shoulder to open the switch. The Bluetooth module in the backpack clip sends an opening command to the positioning terminal. After receiving the opening signal, the Bluetooth module of the positioning terminal controls the CPU to trigger the power module, closes the sleep mode and enters the off-campus mode. After the off-campus mode is turned on, the positioning terminal receives the positioning signal through the integrated satellite module, and sends the positioning signal to the APP installed on the parent's mobile phone in real time through the integrated NB-IOT module. The APP also transmits the student's off-campus positioning information to the positioning management system platform deployed by the school, telling the system that the student is ready to go to school. At this time, a blind spot-free positioning management mode for home and school is established. When the student arrives at the school gate, the electronic tag scanner installed at the school gate scans the electronic tag in the positioning terminal, confirming that the student has arrived at the school. The positioning management system platform sends a command to inform the student's parent's APP that the student has arrived at school, and at the same time switches the positioning terminal worn by the student to the on-campus mode. During this period, the time to school is calculated based on the departure time from home and the arrival time, and compared with the previous statistical data. If the time deviation is too large, or the electronic tag scanner at the school gate has not arrived at school within the time that the student should arrive at school, the system will notify the parent's APP through the platform to inform that the school time is abnormal. If there is any accident, the school and parents can grasp the situation in time to avoid delaying the golden time for rescuing lost students. In school, the student positioning terminal has switched to the school mode by scanning the electronic tag scanner at the school gate. The Bluetooth beacon device is deployed in the school. The student positioning terminal receives the beacon signal at different locations, and then uploads the beacon information to the positioning management system platform through the LORA gateway or WIFI gateway deployed by the school (one of the two in the school). By receiving the field strength information and azimuth information of the Bluetooth beacons at different locations, the student's location is calculated and displayed on the 3D map. Specific places that students cannot go to are set on the positioning management system platform, such as the roof of a building, the school kitchen and other dangerous places. If a student approaches the Bluetooth beacon of these dangerous points, the built-in alarm of the positioning terminal will sound an alarm and upload the alarm information to the positioning management platform to notify the teacher to stop the danger as soon as possible. When a student enters the classroom, the electronic tag scanner at the door of the classroom is scanned to inform the positioning system platform that the student has arrived in the classroom. The platform switches the student's positioning terminal to classroom mode, and the positioning terminal system enters sleep mode to save power consumption of the positioning terminal. Similarly, when the student leaves the classroom after class, the electronic tag scanner at the door of the classroom scans the information of the student's positioning terminal, wakes up the positioning terminal through the positioning management system platform, and switches the working mode to campus mode.When students leave school, the electronic tag scanner at the school gate scans the positioning terminal information, and the positioning management system platform switches the student's positioning terminal to off-campus mode. Just like when they come to school, they are positioned by satellite signals, and the positioning signals are uploaded to the parent's mobile phone APP and the school's positioning management system through the NB-IOT module. Similarly, the positioning system platform calculates the average time it takes to go home through data statistics. If the time is exceeded, the system will issue a reminder so that parents and teachers can know and make judgments at the first time.

[0036] The working principle of the multi-positioning switching management terminal in this example is as follows Figure 3 The working principle is briefly described as follows:

[0037] The core circuit of the multi-positioning switching management terminal (hereinafter referred to as the positioning terminal) is mainly divided into four parts: the MCU main chip uses ST's extremely low-power STM32LO732 chip, which is based on the STM32 series low-power processor with the ARM Cortex-M3 core, and the built-in UART serial port is sufficient to meet the chip data transmission requirements. Positioning part: satellite positioning uses SONY's CXD5603GF, and Bluetooth positioning uses CSR1024 chip; communication part: LORA communication uses SX1278 chip, WiFi communication uses Qualcomm's QCA9331 chip, and NB-IOT communication uses Hi2110 chip; various communication modules and positioning modules are connected to 2 patch antennas through the RF switching switch group, and work with 2 antennas; the inner cover of the positioning terminal is affixed with an electronic tag, and the battery power supply of the entire positioning terminal is controlled by a low-power power management circuit unit. When the positioning terminal works in the mode within the park, the MCU controls the low-power power management unit to turn off the satellite positioning circuit unit and the NB-IOT circuit unit. When the positioning terminal works in the mode outside the park, the MCU controls the low-power power management unit to turn off the LORA circuit unit, the WIFI unit and the Bluetooth circuit unit, thereby achieving extremely low power consumption and increasing the working time of the entire positioning terminal.

[0038] The schematic diagram of the positioning terminal and backpack clamp switch structure of this solution is as follows Figure 4As shown in the figure, the positioning terminal structure is shown in part a of the figure. There is an SOS button on the front of the positioning terminal. When students are in danger on the way home from school or outside the school, they can press and hold the SOS button. The positioning terminal module will upload the rescue information to the positioning management system platform and the parent's mobile phone APP in time so that the students can get the fastest rescue. The backpack clip switch device structure is shown in part b. It consists of a clip body, a push switch and an internal Bluetooth module. The backpack clip is clamped on the strap of the student's backpack, and the push switch faces the inside of the shoulder. When the backpack is on, press the push switch to trigger the Bluetooth module inside to send a command to the student positioning terminal to release the sleep mode, and the student positioning terminal enters the off-campus mode working state.

[0039] It should be noted that, although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures or equivalent process changes made using the contents of the present invention specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
