Description

Positioning reminding method and system based on electronic fence and wearable device

Technical Field

The invention relates to the technical field of positioning, in particular to a positioning reminding method and system based on an electronic fence and wearable equipment.

Background

Nowadays, wearable devices on the market basically have a Positioning function, and are usually positioned by using a Global Positioning System (GPS) System. Based on the GPS positioning function, a supervision end user (such as a parent or a guardian) of the wearable device can track the position of a user end user (such as a child) of the wearable device in real time, and a safety guard function is performed on the child.

However, the GPS positioning function is not suitable for indoor positioning scenarios because the GPS system cannot sense satellite signals due to dense buildings, which results in inaccurate positioning. In other words, after the child enters the indoor environment, the parents cannot track the position of the child in real time, and cannot track the position change of the child in the indoor environment in time. However, in an indoor environment, it is very likely that a child leaves an area where the child should be left (such as a study room or a classroom) and moves to an area where the child should not be left (such as a toilet or a terrace on a higher floor) due to greedy playing, and if the position change of the child in the indoor environment cannot be tracked in time, the child safety is not protected, and the child learning growth is not facilitated.

The execution subject of the embodiment of the present invention is described by taking a wearable device as an example, and it should be understood that the present invention should not be limited in any way. The following detailed description is made with reference to the accompanying drawings.

Example one

Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a positioning reminding method based on an electronic fence according to an embodiment of the present invention. As shown in fig. 1, the electronic fence based location reminding method may include the following steps:

101. when the wearable device is in the indoor environment, the wearable device identifies the floor where the wearable device is located according to the air pressure value corresponding to the position where the wearable device is located.

In the embodiment of the present invention, the air pressure value may specifically be an atmospheric pressure in the ambient air at the position where the wearable device is located, and the air pressure value may be detected by an air pressure sensing device (e.g., a liquid-free barometer) disposed in the wearable device itself, or may be read by an air pressure measuring device (e.g., a mercury barometer hung on a wall) near the position where the wearable device is located. The floor where the wearable device is located may be a specific floor, i.e. 3 th or 6 th floor, etc.

Optionally, the wearable device may acquire an air pressure value corresponding to a location where the wearable device is located in a preset acquisition period, where the acquisition period may be, for example, 0.1s, 0.5s, or 1s, and then obtain a target altitude corresponding to the air pressure value based on a preset corresponding relationship between each air pressure value and an altitude, and calculate and obtain a floor where the wearable device is located according to the target altitude and a local altitude reference value, where the local altitude reference value is used to represent an altitude of a floor.

Considering that the conventional wearable device or step-counting device can only count steps of motions in a horizontal plane range, such as ordinary walking and running, but actually, when people overcome gravity to do some motions of climbing mountains and stairs, the consumed calories are much larger, and the result obtained by calculating calories with the conventional wearable device or step-counting device is inaccurate. Therefore, there is a need for calculating calories more accurately to truly reflect the daily consumption of calorie data by a user wearing a wearable device.

As an optional implementation manner, if the wearing user of the wearable device is in the process of exercise, the wearable device may determine a current exercise direction and an exercise speed according to a change size and a change time of an air pressure value corresponding to a position where the wearable device is located, determine a current exercise type according to the exercise direction and the exercise speed, and obtain calorie data consumed by the wearing user of the wearable device in the current exercise type based on a preset corresponding relationship between each exercise type and calorie consumption.

Exemplarily, when the change magnitude of the air pressure value is within a first preset range, determining that the current motion type is walking motion; when the change of the air pressure value periodically rises and then falls, and the difference value of rising and falling every time is in a second preset range, determining that the current exercise type is running or jumping exercise; and when the change of the atmospheric pressure value continuously rises, determining that the current motion type is climbing or mountain climbing motion.

Through the embodiment, the calorie can be calculated more accurately through the air pressure value, so that the daily consumed calorie data of the wearing user of the wearable device can be reflected truly.

102. The wearable device determines location information of the wearable device in the floor.

Optionally, indoor positioning may be performed based on wireless networks such as WIFI, bluetooth, or ZigBee to obtain location information of the wearable device in a floor, where the location information may specifically be a certain unit, a certain storefront, a certain washroom, and the like, for example, if the floor where the wearable device is located is a 3-th floor, the location information may be 302 units, and the wearable device is 302 units in the 3-th floor; or, if the location information is an east-oriented restroom, the wearable device is in an east-oriented restroom of the 3 rd building.

103. The wearable device takes the floor and the position information as the indoor position of the wearable device.

104. If the indoor position is detected to move from the inside of the electronic fence to the outside of the electronic fence, the wearable device sends first prompt information to a supervision terminal of the wearable device.

The electronic fence is a two-dimensional or three-dimensional area.

It can be understood that, if the electronic fence is a two-dimensional area, the electronic fence is only a designated horizontal plane area, without considering the height range, when determining whether the indoor location moves from inside to outside of the electronic fence, the floor included in the indoor location is not considered, and only the location information included in the indoor location is considered, that is, when the location information moves from inside to outside of the designated horizontal plane area, the indoor location can be considered as moving from inside to outside of the electronic fence; if the electronic fence is a three-dimensional area, the electronic fence comprises a designated horizontal plane area and a designated height range, and when judging whether the indoor position moves from the inside of the electronic fence to the outside of the electronic fence, the floor and the position information included in the indoor position need to be considered, namely when the position information moves from the inside of the designated horizontal plane area to the outside of the designated horizontal plane area or when the floor moves from the inside of the designated height range to the outside of the designated height range, the indoor position can be considered to move from the inside of the electronic fence to the outside of the electronic fence.

In the embodiment of the invention, the electronic fence can be a regular circle, a cylinder, a triangle, a triangular prism, a rectangle, a cuboid, a square or a cube and the like; the electronic fence can also be an irregular convex hull pattern, a triangular pyramid, an irregular cube, or the like.

It can be seen that, with the implementation of the method described in fig. 1, when the wearable device is in an indoor environment, according to an air pressure value corresponding to a location of the wearable device, a floor where the wearable device is located is identified, then location information of the wearable device in the floor is determined, the floor and the location information are used as an indoor location of the wearable device, if it is detected that the indoor location moves from inside to outside of the electronic fence from inside of the electronic fence, the first prompt information is sent to the monitoring terminal of the wearable device, and when the wearable device is in the indoor environment, a location change condition of the wearable device can also be fed back to the monitoring terminal of the wearable device in time, so that the monitoring terminal user can track the location change condition of the wearable device user in time.

Example two

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating another positioning reminding method based on an electronic fence according to an embodiment of the present invention. As shown in fig. 2, the electronic fence based location reminding method may include the following steps:

201. the wearable device detects a satellite positioning signal strength of the wearable device.

In the embodiment of the present invention, the wearable device may capture a satellite signal through a GPS system to obtain the satellite positioning signal strength, or capture a satellite signal through a beidou satellite navigation system to obtain the satellite positioning signal strength, which is not specifically limited.

202. If the satellite positioning signal strength is changed from reaching the preset threshold value to being smaller than the preset threshold value, the wearable device determines the last moment when the satellite positioning signal strength reaches the preset threshold value.

It is understood that the preset threshold may be a critical value indicating that the satellite positioning signal strength is sufficient for accurate positioning and insufficient for accurate positioning, and when the satellite positioning signal strength reaches (i.e. is greater than or equal to) the critical value, it is considered that accurate satellite positioning can be performed; when the satellite positioning strength is smaller than the critical value, the satellite positioning is not performed any more or the satellite positioning result is ignored due to larger error. The critical value can be a parameter which is analyzed and preset by a developer according to actual conditions and a large amount of experimental data.

Since a transition of the satellite positioning signal strength from reaching the preset threshold to being less than the preset threshold may be considered a transition process, the last time before the transition when the satellite positioning signal strength has reached the preset threshold may be determined as the last time.

203. The wearable device obtains a satellite positioning result determined by the wearable device based on the satellite positioning signal at the last moment.

It should be noted that, before the transition, that is, when the satellite positioning signal strength reaches the preset threshold, the wearable device may perform satellite positioning based on the satellite positioning signal in a preset positioning period. Thus, after step 202 is executed, the wearable device may determine whether the last time belongs to a positioning time of a certain positioning period, and if so, adopt a satellite positioning result of the wearable device at the last time; if not, the satellite positioning result of the positioning cycle to which the last moment belongs is adopted.

204. And the wearable equipment determines the building area where the wearable equipment is located according to the satellite positioning result.

205. The wearable equipment judges whether the building area is matched with the appointed building area. If yes, go to step 206; otherwise, step 212 is performed.

The designated building area can be specifically a certain target cell, a certain target teaching building, a certain target square or a certain target office building and the like. It is understood that the designated building area includes at least one independent building, and the designated building area is obtained from the trip information preset by the user.

206. And if the short-distance communication verification information of the wearable device is read by the short-distance communication device, the wearable device determines a target building where the wearable device is located according to the building information corresponding to the short-distance communication device. Wherein, the target building is a certain building in the building area.

In the embodiment of the invention, the corresponding relation between each short-distance communication device and each building information can be stored, and the corresponding relation can be stored in the wearable device, a background server of the wearable device or a terminal device connected with the wearable device. When the short-distance communication verification information of the wearable device is read by one short-distance communication device, the target building where the wearable device is located can be determined to verify through the short-distance communication verification information according to the building information corresponding to the short-distance communication device, namely, the target building is accessed.

It should be noted that the short-range Communication verification information may specifically be Near Field Communication (NFC) verification information, and the short-range Communication device may specifically be an NFC access control device. The NFC verification information can be stored in an NFC electronic tag of the wearable device, the NFC electronic tag can be arranged in the wearable device, wireless communication connection can also be established with the wearable device, and even a verification card bound with a wearing user of the wearable device can be used, such as a bus card, a door card or a citizen card.

207. If the duration that the satellite positioning signal intensity is smaller than the preset threshold reaches the preset duration, the wearable device judges that the wearable device enters the indoor environment from the outdoor environment.

In consideration of the fact that a wearing user of the wearable device may shuttle among high-rise buildings to cause instability of satellite positioning signal strength, so that the satellite positioning signal strength may fluctuate, in some possible embodiments, in order to improve the determination accuracy of the wearable device entering the indoor environment from the outdoor environment, after the satellite positioning signal strength changes from reaching a preset threshold value to being smaller than the preset threshold value, when the duration of the satellite positioning signal strength being smaller than the preset threshold value reaches a preset duration, it may be determined that the wearable device enters the indoor environment from the outdoor environment. Conversely, in some other possible embodiments, the wearable device may be determined to exit from the indoor environment to the outdoor environment when the duration of the satellite positioning signal strength reaching the preset threshold reaches a certain specified duration after the satellite positioning signal strength transitions from being less than the preset threshold to reaching the preset threshold.

In this embodiment, after the satellite positioning signal strength is changed from reaching the preset threshold value to being smaller than the preset threshold value, whether the short-distance communication verification information of the wearable device is read by the short-distance communication device is judged, if yes, and the duration that the satellite positioning signal strength is smaller than the preset threshold value reaches the preset duration, the wearable device is judged to enter the indoor environment from the outdoor environment, so that the judgment accuracy rate of the wearable device entering the indoor environment from the outdoor environment can be further improved, and the determination accuracy rate of the indoor position of the wearable device is further improved.

208 to 209. For the descriptions of steps 208 to 209, please refer to the detailed descriptions of steps 101 to 102 in the first embodiment, which is not repeated herein.

210. The wearable device takes the target building, the floor and the position information as the indoor position of the wearable device.

211. If the indoor position is detected to move from the inside of the electronic fence to the outside of the electronic fence, the wearable device sends first prompt information to a supervision terminal of the wearable device.

212. The wearable device sends out second prompt information.

The second prompt information is used for sending an early warning signal about a wrong building area to a wearing user of the wearable device. Optionally, the manner in which the wearable device sends the second prompt message may specifically be: the wearable device judges whether a display screen of the wearable device is in a bright screen state; if the display screen of the wearable device is not in a bright screen state, the wearable device controls the loudspeaker to send out a sound signal corresponding to the second prompt message in a preset sound production mode; and/or the wearable device controls the LED light-emitting plate to emit a light signal corresponding to the second prompt message in a preset color and/or a preset flashing frequency; and/or the wearable device controls the wearable device to send out a vibration signal corresponding to the second prompt message at a preset vibration frequency.

Illustratively, the preset sounding pattern may be a 500Hz high level lasting 0.5s alternating with a 0Hz low level lasting 2 s; alternatively, a 1075Hz high level lasting 1s alternates with a 925Hz low level lasting 1 s; alternatively, a linear rise from 500Hz low to 1200Hz high within 10ms alternates with a linear fall from 1200Hz high to 500Hz low within 1 s.

Further exemplary, the preset color may be blue light having a wavelength of 0.480 to 0.455 μm; or yellow light with the wavelength of 0.597-0.577 μm; or red light with the wavelength of 0.760-0.622 μm.

As another example, the preset blinking frequency may be a specific numerical value such as 2Hz or 3 Hz; the preset vibration frequency can be 5Hz or 7 Hz.

By the embodiment, the early warning prompt is carried out from one or more aspects of auditory sensation, visual sensation and tactile sensation, and multi-dimensional sound, light and mechanical early warning prompt can be realized, so that a wearing user of the wearable device can feel the existence of the problem through one or more aspects of auditory sensation, visual sensation and tactile sensation, and then the route is planned again.

Additionally, if the display screen of the wearable device is in a bright screen state, the wearable device can control the display screen to pop up a pop-up window containing second prompt information, and the second prompt information in the pop-up window is preset early warning text information. Further optionally, the second prompt information in the pop-up window may also be an electronic map, in which the positions of the building area and the designated building area and the relative direction information of the building area and the designated building area are respectively marked, so that a user wearing the wearable device can visually conveniently and quickly know the existence of a problem, and thus an optimal route can be re-planned at a higher speed so as to avoid time delay.

Compared with the method described by implementing fig. 1, the method described by implementing fig. 2 can also determine whether the wearable device enters the indoor environment from the outdoor environment by using the satellite positioning signal intensity, determine the building area where the wearable device is located by using the satellite positioning result corresponding to the last moment before the satellite positioning signal intensity is changed from strong to weak, and send out second prompt information to send out an early warning signal about a wrong building area to a wearing user of the wearable device if the building area is determined not to be matched with the specified building area, so that the wearing user knows the existence of the problem, and further plans the route again.

In addition, after the satellite positioning signal strength is changed from reaching the preset threshold value to being smaller than the preset threshold value, whether short-distance communication verification information of the wearable device is read by the short-distance communication device or not is judged, if yes, the duration that the satellite positioning signal strength is smaller than the preset threshold value reaches the preset duration, the wearable device is judged to enter the indoor environment from the outdoor environment, therefore, the judgment accuracy rate of the wearable device entering the indoor environment from the outdoor environment can be further improved, and the determination accuracy rate of the indoor position of the wearable device is further improved.

The wearable device may have a function of reading (and sometimes writing) the tag information, or the wearable device may be provided with an electronic tag reading device, and the electronic tag reading device is used to read (and sometimes may also write) the tag information, so that when the electronic tag stored in the electronic tag is read by the wearable device, the location information of the electronic tag may be used as the location of the wearable device in the floor.

304. The wearable device determines a plurality of target image monitoring devices which are arranged in a floor and detect user images of a wearing user of the wearable device.

It can be understood that the image monitoring device may be a camera for monitoring arranged in a floor, and each camera has a corresponding set position when arranged in the floor, so that if the camera detects a user image of a wearing user of the wearable device, it indicates that the wearing user is present in a monitoring range area of the camera.

As an optional implementation manner, when the wearable device is successfully connected to any WIFI access point in the floor, the wearable device may send a user image of a wearing user of the wearable device to a control service console of the floor through a WIFI signal of the WIFI access point, where the control service console is configured to control each WIFI access point and each image monitoring device in the floor, and based on this, the wearable device may receive shared information sent by the control service console, where the shared information includes a unique code used to indicate that each target image monitoring device that detects the user image and a set position of each target image monitoring device in the floor; and determining a plurality of target image monitoring devices which are arranged in the floor and detect the user images of the wearable devices wearing the users according to the shared information.
