For example, the interactive tablet positioning device in this embodiment includes a large interactive tablet device and a server.
The interactive tablet positioning device is provided with at least one type of operating system, wherein the operating system comprises, but is not limited to, an android system, a Linux system and a Windows system. The interactive tablet positioning device may install at least one application program based on the operating system, where the application program may be an application program carried by the operating system, or may be an application program downloaded from a third party device or a server.
For ease of understanding, the embodiments are described with respect to a large interactive tablet device and server as the interactive tablet positioning device.
FIG. 1 is a flow chart of an interactive tablet location method for a server according to one embodiment of the present application. Referring to fig. 1, the interactive tablet positioning method provided by the embodiment of the present application includes:
s110, receiving WIFI signal intensity information uploaded by the tablet equipment to be positioned, wherein the WIFI signal intensity is detected when a second WIFI module of the tablet equipment to be positioned scans a first WIFI module of preset control equipment, and the spatial position of the control equipment is fixed.
The tablet equipment is a large interactive tablet, the large interactive tablet is generally arranged in a space area such as a teaching building or an office building, and the centralized control system is used for controlling all the large interactive tablet in the area. However, the areas such as teaching building and office building have numerous floors, the space position is complex, and the base station or satellite positioning technology is difficult to realize accurate positioning. In these areas, the arrangement of the WIFI devices is necessary, so that the first WIFI module assembled by the existing WIFI devices and the tablet devices is utilized under the condition that the tablet device hardware is not updated, and the tablet devices can be accurately positioned in buildings such as teaching buildings and office buildings based on signal attenuation rules and triangle positioning rules, so that the centralized control system can accurately sense the spatial positions of the tablet devices in the corresponding control areas in real time, and realize more efficient and comprehensive control.
Specifically, the control device with a fixed position is selected in advance in a building such as a teaching building or an office building, the control device can be a tablet device for starting a hot spot, a router with a WIFI access point function and the like, and first space position information of the control device is recorded in a server of the centralized control system. The control equipment is selected only by ensuring that the WIFI signal of the selected equipment can cover most areas in the building. And constructing a datum position reference network through the control equipment selected in advance, and accurately positioning by the centralized control system as long as the flat-panel equipment is positioned in the range of the datum position reference network.
Based on the information, the to-be-positioned flat panel device in the reference position reference network starts a site mode of a first WIFI module of the to-be-positioned flat panel device, second WIFI module information of all control devices in the maximum detection range is scanned through the first WIFI module, and the information comprises WIFI signal intensity information of all the control devices. Further, the WIFI signal intensity information acquired by the tablet equipment to be positioned is uploaded to the server, and the WIFI signal intensity information can be understood to comprise the WIFI signal intensity and corresponding control equipment. On the other hand, the server receives the WIFI signal intensity information uploaded by the tablet equipment to be positioned, and positions the tablet equipment to be positioned according to the WIFI signal intensity information.
And S120, calculating the spatial distance between the tablet equipment to be positioned and the control equipment based on the signal attenuation rule according to the WIFI signal intensity information.
Fig. 2 is a schematic diagram of a mapping relationship between a distance and a signal attenuation value according to an embodiment of the present application. Referring to fig. 2, since the WIFI signal strength propagates in space and decays with increasing distance, a certain mapping relationship is formed between the distance and the signal attenuation value, and fig. 2 shows the mapping relationship between the distance and the signal attenuation value when the WIFI frequency band is 2.4 GHZ. As can be seen from fig. 2, therefore, according to the WIFI intensity information, a WIFI signal attenuation value from the first WIFI module to the second WIFI module can be determined, and according to a mapping relationship between the distance and the signal attenuation value, a distance between the first WIFI module and the second WIFI module is determined, that is, a distance between the tablet device to be positioned corresponding to the first WIFI module and the control device corresponding to the second WIFI module is determined.
S130, acquiring first spatial position information of the control equipment, and calculating second spatial position information of the to-be-positioned flat equipment based on the triangular positioning rule according to the spatial distance between the to-be-positioned flat equipment and three or more control equipment and the first spatial position information of the corresponding control equipment.
Fig. 3 is a schematic diagram of triangulation according to an embodiment of the present application. Referring to fig. 3, three control devices with determined distances from the device to be positioned are selected, the distance from the device to be positioned to the three control devices is taken as a radius, the second spatial positions of the three control devices are taken as sphere centers, three spheres are drawn, the intersection points of the three spheres are the positions of the device to be positioned, namely, the first spatial position information of the control devices with determined distances from the device to be positioned and the corresponding positions are used for determining the second spatial position information of the device to be positioned. And under the condition of accurate distance, the balls drawn by the three control devices and more than three control devices are intersected at one point, so that the second spatial position information of the device to be positioned can be determined by selecting more than three control devices.
It can be understood that if there is an inaccurate distance between one control device and the device to be positioned in the three control devices, then the three balls constructed by the three control devices cannot intersect at one point, so when the balls constructed by the three control devices have no intersection point, a new control device is added, and the balls of the new control device are drawn, so that the new balls and the original balls form a three-ball intersection point. Furthermore, in order to improve the positioning accuracy, after the second spatial position of the equipment to be positioned is obtained by calculation, the positioning result can be checked by a worker, and if the checking is not passed, the second spatial position of the equipment to be positioned is recalculated.
For example, the preset control device does not include a tablet device, and the first spatial location information of the preset control device may be obtained in the following two ways:
The first acquisition mode is to determine three-dimensional world coordinates of the control device by installing a base station or a satellite positioning module on the control device, and the three-dimensional world coordinates are used as first spatial position information of the control device.
The second acquisition mode is to determine first spatial position information of three control devices through a satellite positioning technology, select one control device in a signal coverage range of the three control devices, place a mobile phone terminal on the control device, start a WIFI site mode of the mobile phone terminal, acquire WIFI signal intensity information between the mobile phone terminal and the three control devices through the mobile phone terminal, determine three-dimensional world coordinates of the mobile phone terminal based on a signal attenuation rule and a triangular positioning rule, and take the three-dimensional world coordinates as the first spatial position information of the control device. Further, in the signal coverage of the four control devices, one control device is selected, and the first spatial location information of the control device is determined by using the same method as the above method, so that the first spatial location information of all the control devices can be determined.
In summary, according to the interactive tablet positioning method for a server provided by the embodiment, by pre-selecting a control device with a fixed position and pre-storing first spatial position information of the control device, according to the fact that WIFI signal intensity information is detected when the tablet device to be positioned scans the preset control device, based on the principle that WIFI signal intensity is weakened along with the increase of a transmission distance and the mapping relation between the distance and a signal attenuation value, the distance between the tablet device to be positioned and the control device can be determined. Further, based on the principle of triangular positioning, according to the distance between the tablet equipment to be positioned and three or more control equipment and the first spatial position information of the corresponding control equipment, the second spatial position information of the tablet equipment to be positioned can be determined. Through the technical means, the problem that the existing centralized control system cannot acquire accurate position information of the large-scale interactive flat-panel equipment is solved.
Furthermore, the centralized control system provided by the embodiment has the function of accurately positioning the large interactive flat-panel device in real time, so that a series of service functions based on the position information can be developed based on the centralized control system of the embodiment. For example, for newly added tablet devices in teaching buildings and office buildings, an administrator does not need to manually input second spatial position information of the newly added tablet devices in the system, and the second spatial position information of the newly added tablet devices can be quickly and accurately acquired by a server of the centralized control system and automatically stored.
FIG. 4 is a flow chart of another interactive tablet location method for a server provided in one embodiment of the application. The present embodiment is embodied on the basis of the above embodiment. Referring to fig. 4, the interactive tablet positioning method provided in this embodiment includes:
s210, a first positioning instruction is sent to the control equipment, so that a first WIFI module of the control equipment is switched to a WIFI access point mode.
When the tablet device logs on the internet through the second WIFI module, the second WIFI module serves as a wireless access point in the scanning detection range of the station, and the wireless access point is the first WIFI module of the control device. Therefore, in order to obtain the WIFI signal intensity information between the device to be located and the control device, the first WIFI module of the control device needs to be switched to the WIFI access point mode. It can be appreciated that the control device includes some tablet devices, and the second WIFI modules of these tablet devices typically operate in a WIFI site mode or are turned off, so that the WIFI access point modes of these tablet devices need to be turned on, and for routers, the WIFI access point modes are typically all WIFI access point modes.
S220, sending a second positioning instruction to the tablet equipment to be positioned so that a second WIFI module of the tablet equipment to be positioned is switched to a WIFI site mode.
For example, the server may send a second positioning instruction to the tablet device to be positioned that wants to determine the location information, where the tablet device to be positioned receives the second positioning instruction to switch its second WIFI module to the WIFI site mode, and scan all WIFI access points in the detection range through the second WIFI module and obtain corresponding WIFI signal strength information.
S230, receiving WIFI signal intensity information uploaded by the tablet equipment to be positioned, wherein the WIFI signal intensity is detected when a second WIFI module of the tablet equipment to be positioned scans a first WIFI module of preset control equipment, and the spatial position of the control equipment is fixed.
S240, based on a signal attenuation rule, calculating to obtain the spatial distance between the tablet equipment to be positioned and the control equipment according to the WIFI signal intensity information.
S250, acquiring first spatial position information of the control equipment, and calculating second spatial position information of the to-be-positioned flat equipment based on the triangular positioning rule according to the spatial distance between the to-be-positioned flat equipment and three or more control equipment and the first spatial position information of the corresponding control equipment.
For example, steps S230 to S250 may refer to steps S110 to S130 for implementation.
S260, setting the tablet device determining the second spatial location information as a new control device.
For example, the tablet device is a large interactive tablet, the spatial location information of the tablet device is not changed, and the characteristic meets the condition that the location of the control device is fixed, so that the tablet device determining the second spatial location information can be used as a new control device to be added into the reference location reference network, the coverage area of the reference location reference network is enlarged, or the distribution of the reference location reference network is thinned.
S270, receiving WIFI signal intensity information uploaded by the indoor mobile terminal to be positioned, and determining third spatial position information of the mobile terminal to be positioned according to the WIFI signal intensity information and the first spatial position information of the corresponding control equipment.
It can be appreciated that the tablet device is typically disposed in a teaching room of a teaching building or a conference room of an office building, and for some indoor spaces where routers are not installed, the coverage area of router signals in a floor area is too large to accurately locate indoor mobile terminals. Therefore, the tablet device with the determined position in the classroom or conference room can be used as a control device, so that the mobile terminal with the WIFI site function in the room can be positioned, and the mobile terminal comprises, but is not limited to, a tablet for students, a mobile phone, a smart wearable device and the like. Based on the positioning of the mobile terminals, the positioning of personnel can be realized, for example, the accurate positions of students in classrooms and even schools can be dynamically monitored, and the personal safety of the students in the schools is improved.
S280, acquiring safety position range information of the tablet equipment to be positioned, and monitoring whether the second spatial position is in the safety position range according to the safety position range information and the corresponding second spatial position information.
Illustratively, the second spatial location information of the tablet device is dynamic digital information, and the centralized control system may set the geo-location fence to monitor the tablet device in real time based on the spatial location information of the tablet device. Specifically, the centralized control system periodically issues a second positioning instruction to the tablet equipment, and determines second spatial position information of the tablet equipment in real time. And presetting safety position range information of the tablet equipment, taking the safety position range as a geographic position fence of the tablet equipment, and monitoring whether the tablet equipment is in the position fence or not through the position relation between the second spatial position and the safety position range.
And S290, generating an alarm signal and displaying second spatial position information when the second spatial position exceeds the safety position range.
The large interactive flat plate is generally and fixedly arranged indoors, if the second spatial position of the flat plate device exceeds the position fence, the flat plate device is indicated to be possibly stolen, so that when the abnormal condition that the second spatial position exceeds the position fence is monitored, the abnormal condition of the flat plate device at which position of a user is reminded is actively alarmed, the user is convenient to contact nearby security personnel to check the position, and property safety is improved.
On the other hand, in order to ensure that the tablet equipment can actively send WIFI signal intensity information to the server, an interactive tablet positioning method running on the tablet equipment is provided aiming at the interactive tablet positioning method running on the server, and corresponds to the interactive tablet positioning method running on the server.

And S310, after the power-on and the power-on, controlling the second WIFI module to scan the first WIFI module of the preset control equipment, and acquiring corresponding WIFI signal intensity information.
By way of example, the large interactive tablet has certain mobility in teaching and office buildings due to the existence of foot frames, and when the position of the tablet equipment changes, the existing centralized control system cannot actively determine the position of the tablet equipment after moving, so that the tablet equipment is not convenient for an equipment manager to check and examine the tablet equipment regularly. The tablet device is generally powered by a plug-in power, and does not have battery power supply capability, so that power must be cut off when the tablet device is moved for a larger distance, and the centralized control system sends a first positioning instruction to the tablet device in the power-off process so as to determine the spatial position information of the tablet device. Therefore, this embodiment proposes that, when the tablet device is powered on next time after power failure, the WIFI signal intensity information between the second WIFI module of the tablet device and the first WIFI module of the control device is actively reported to the server of the centralized control system, so that the server determines the second spatial position information of the tablet device according to the WIFI signal intensity information, and the centralized control system simply and efficiently controls the spatial position of the tablet device in real time.

Further, based on the triangle positioning principle, according to the distance between the tablet equipment to be positioned and three or more control equipment and the first spatial position information of the corresponding control equipment, the second spatial position information of the tablet equipment to be positioned can be determined, and a user does not need to manually input the spatial position of each tablet equipment to be positioned in the centralized control system, so that the management convenience of the centralized control system is improved, and the user experience is improved. In addition, the spatial position information of the tablet equipment is not static text information any more, but dynamic digital information, the centralized control system can dynamically control the tablet equipment based on the spatial position information of the tablet equipment, and a geographic position fence can be set to realize anti-theft alarm of the equipment.

Based on the mode that WIFI signal intensity information is actively reported after the flat-panel device is electrified and started, the centralized control system simply and efficiently controls the spatial position of the flat-panel device in real time.
