Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to solve the technical problem that cost required for monitoring the position of an object is high by adopting a mode based on image acquisition and image recognition in the prior art, in some embodiments of the present application, a solution is provided.
Fig. 1 is a schematic structural diagram of a position monitoring system according to an exemplary embodiment of the present application, and as shown in fig. 1, the position monitoring system 100 includes: a first terminal 10, a server 20, a plurality of object marker terminals 30 located in a first space.
In the position monitoring system 100, the first terminal 10 may be implemented as an electronic terminal having a display function as well as a communication function. For example, in some embodiments, the first terminal 10 may be implemented as a mobile phone, a tablet computer, a computer device, a smart wearable device, etc., including but not limited to this. In the position monitoring system 100, the first terminal 10 is mainly used to assist a user in position monitoring of an object in the first space.
The first space may be any monitored place, for example, a supermarket, a museum, a factory, a zoo, and the like, which includes but is not limited to this embodiment. Within the first space, at least one object is present.
Wherein, the realization form of the first space is different, and the realization form of the object is also different. For example, the first space is realized in a museum, the object can be a sculpture, calligraphy and painting and other collections to be displayed, and the user can monitor the position change of the collections through a mobile phone to determine the safety of the collections; when the first space is implemented as a zoo, the object can be an animal, and a manager can monitor the position change of the animal through a computer and identify the living state of the animal. When the first space is realized as a museum, an exhibition hall, a science and technology museum and a scenic spot, the object can also be realized as a tourist in the first space, and the position of the other side in the first space can be mutually monitored between different tourists so as to avoid missing.
In the position monitoring system 100, the object marking terminal 30 is located in the first space and is mainly used for marking the object in the first space. The number of the object marker terminals 30 in the first space may be multiple (two or more, depending on the actual application scenario).
Generally, an object marker terminal 30 may be associated with an object in a first space and may receive and transmit wireless signals. Wherein each object marker terminal is movable with its associated object. Furthermore, the other device may perform position monitoring on the object in the first space by detecting a change in the position of the object marker terminal. The association relationship between the object tag terminal and the object can be stored in the server 20 for subsequent use.
In some exemplary embodiments, when associating the object tag terminal with the object, the respective identifiers of the object tag terminal and the object may be obtained, and a one-to-one correspondence relationship between the identifier of the object tag terminal and the identifier of the object may be established. The identification identifier of the object tag terminal may be a device identifier, a Media Access Control Address (MAC Address), an account number, or the like. The identification of the object may be the name, number, etc. of the object, depending on the specific application scenario.
For example, a correspondence relationship between the goods with the id a and the object marker terminal with the id a 'may be established, and a correspondence relationship between the goods with the id B and the object marker terminal with the id B' may be established.
In some exemplary embodiments, when associating the object tag terminal with the location of the object, optionally, the object tag terminal and the object tagged by it may be bound together.
For example, in some embodiments, the object marker terminal may be implemented as an electronic label that may be affixed; in this case, the object marker terminal may be adhered to the exterior of the object marked thereby so that the object marker terminal may move with the object marked thereby.
For example, in other embodiments, the object marker terminal may be implemented as a lightweight, portable wireless communication module; in this case, the object marking terminal may be fixed inside the object marked by it or fixed outside the object marked by it.
For example, in still other embodiments, the object marker terminal may be implemented as a portable cell phone, bracelet, smart watch, or the like; in this case, the object marker terminal may be bound to or worn by the object marked by the object marker terminal in a wearing manner.
In the present embodiment, a communication connection is established between the first terminal 10 and the server 20, and based on the communication connection, the first terminal 10 may transmit a request for viewing an object in the first space to the server 20 in response to a request of a user. The request may be initiated for any one or more objects in the first space, which is not limited in this embodiment.
The server 20, upon receiving the request, may obtain the relative positions between the plurality of terminals in the first space in response to the request for the first terminal 10 to view the object in the first space. Wherein the plurality of terminals includes a first terminal 10 and a plurality of object marker terminals 30 within a first space. It should be understood that the plurality of object tag terminals 30 includes an object tag terminal bound with an object requested to be viewed by the first terminal 10. Then, taking the relative distance between any two terminals in the first space as a distance unit, and according to the relative positions of the plurality of terminals, generating an object relative position map corresponding to the first space, where the object relative position map shows the relative position relationship between the plurality of objects in the first space and the relative position relationship between each object and the first terminal 10.
After generating the object relative position map, the server 20 may transmit the object relative position map to the first terminal 10. Further, the first terminal 10 may view a relative position with respect to the object within the first space on the object relative position map.
In some embodiments, the server 20 may be within a first space; in this embodiment, the first terminal 10 and the server 20 may communicate with each other by using a wired communication method or a wireless communication method. The WIreless communication mode includes short-distance communication modes such as bluetooth, ZigBee, infrared, WiFi (WIreless-Fidelity), and long-distance WIreless communication modes such as LORA.
In other embodiments, the server 20 may be remote with respect to the first space. In this embodiment, a wireless communication mode based on a mobile network may be used between the first terminal 10 and the server 20. When the mobile network is connected through a mobile communication network, the network format of the mobile network may be any one of 2G (gsm), 2.5G (gprs), 3G (WCDMA, TD-SCDMA, CDMA2000, UTMS), 4G (LTE), 4G + (LTE +), 5G, WiMax, and the like, which includes but is not limited to this embodiment.
In this embodiment, the server 30 may be implemented as a device such as a conventional server, a cloud host, a virtual center, and the like, which is not limited in this embodiment. The server device mainly includes a processor, a hard disk, a memory, a system bus, and the like, and is similar to a general computer architecture, and is not described in detail.
In this embodiment, when there is a need for the first terminal to view the object in the first space, the object relative position map corresponding to the first space may be generated according to the relative positions between the first terminal and the plurality of object marker terminals in the first space, and then the first terminal may view the relative position relationship with the object in the first space based on the object relative position map. In the embodiment, the process of acquiring the relative position map of the object reduces the dependence on the self-positioning data of the equipment, the calculated amount is small, and the cost required by position monitoring is favorably and effectively reduced.
In some exemplary embodiments, one way for the server 20 to obtain the relative positions between the first terminal and the plurality of terminals within the first space may include:
calculating the relative distance between the first terminal and each object mark terminal in the first space; then, the relative positions of the plurality of terminals in the first space are obtained according to the relative distance between every two object marking terminals in the first space and the relative distance between the first terminal and each object marking terminal in the first space. As will be described in detail below.
Wherein, optionally, when calculating the relative distance between the first terminal and each object marker terminal in the first space, the calculation may be based on the attenuation characteristics of the wireless signal as it travels with distance. In such an embodiment, the server 20 may first obtain the strength of the wireless signal emitted by each object tag terminal detected by the first terminal.
Then, the server 20 may calculate the relative distance between the first terminal and each target tag terminal according to the set scaling factor and the strength of the wireless signal sent by each target tag terminal detected by the first terminal. The scaling factor is used for converting the intensity of the received wireless signal into a distance according to an intensity attenuation relation when the wireless signal propagates along with the distance, and is shown in the following formula 1:
d2＝C2(R0-R) formula 1
In formula 1, d represents a relative distance, C is a scaling factor, R is a received signal strength of a wireless signal transmitted from a target tag terminal, and R is0The signal intensity value of the signal transmitting device, which is ideally unattenuated, may also be the average of the signal intensities measured by placing the object marker terminal in infinite proximity to signal receiving devices of different models.
Of course, in other embodiments, the server 20 may also obtain the signal strength of the wireless signal sent by the first terminal and received by the target tag terminal, so as to correct the strength of the wireless signal sent by the target tag terminal and received by the first terminal. For example, if the strength of the wireless signal received by the first terminal from the target tag terminal a is S1 and the strength of the wireless signal received by the target tag terminal a from the first terminal is S2, R is (S2+ S2)/2.
It should be noted that, in the embodiment of the present application, when the map of the relative position of the object corresponding to the first space is drawn by using the relative position between the first terminal and the object marking terminal, the actual distance between different devices does not need to be considered. Therefore, when calculating the relative distance between the first terminal and the object marker terminal, it is preferable that C is 1, and R is00 to further reduce the amount of computation.
For example, when the signal strength of the wireless signal sent by the object tag terminal a received by the first terminal is-30 dB, the distance between the first terminal and the object tag terminal a can be calculated and obtained as 5.477 according to the above formula 1; for another example, when the signal strength of the wireless signal received by the first terminal from the object tag terminal B is-60 dB, the distance between the first terminal and the object tag terminal a may be calculated to be 7.746 according to the above formula 1, which is not described again.
Alternatively, after determining the relative distances between the first terminal and the plurality of object marker terminals in the first space based on the above formula 1, then, the relative positions between the plurality of terminals in the first space may be obtained according to the relative distance between every two object marker terminals in the first space and the relative distance between the first terminal and each object marker terminal in the first space.
The relative distance between every two object marking terminals in the first space can be obtained by adopting the following method: alternatively, a communication connection may be established between each object tag terminal and the server 20, and each object tag terminal may detect a wireless signal transmitted from another object tag terminal and transmit a strength value of the detected wireless signal to the server 20. The server 20 may calculate the relative distance between two object mark terminals according to formula 1.
Optionally, in some exemplary embodiments, when the relative positions of the plurality of terminals are obtained according to the relative distance between every two object marker terminals in the first space and the relative distance between the first terminal and each object marker terminal in the first space, any three devices may be grouped, and a triangle may be constructed according to the relative distances of the three devices. The first terminal and the first object marker terminal and the second object marker terminal in the first space will be described as an example. The first object marker terminal and the second object marker terminal are any two devices of the plurality of object marker terminals in the first space, and are defined as "first" and "second" herein, which are only used for convenience of description.
As shown in fig. 2, for the first object mark terminal and the second object mark terminal of the first terminal and the plurality of object mark terminals, a relative distance of the first object mark terminal and the second object mark terminal may be taken as a first side of the triangle, a relative distance of the first terminal and the first object mark terminal may be taken as a second side of the triangle, and a relative distance of the first terminal and the second object mark terminal may be taken as a third side of the triangle. Based on these three edges, a triangle can be uniquely determined. Based on the triangle, a relative position between the first terminal, the first object marker terminal, and the second object marker terminal may be determined, the relative position including a relative distance and a relative direction between the two terminals, as shown in FIG. 2.
Then, the position of the third terminal relative to the triangle can be determined according to the relative distance between the third object marking terminal and the first terminal, the first object marking terminal and the second object marking terminal, and the positions of other object marking terminals relative to the triangle can be calculated by analogy.
After the relative positions of the plurality of terminals are determined based on the method, an object relative position map corresponding to the first space can be generated. A typical object relative position map may be as shown in figure 3 a.
Optionally, in this embodiment, when generating the object relative position map, the minimum relative distance may be selected from the relative distance between the first terminal and each object marking terminal and the relative distance between two object marking terminals; and then, generating an object relative position map corresponding to the first space according to the relative positions between the first terminal and the plurality of object marking terminals and the relative positions between every two object marking terminals by taking the minimum relative distance as a distance unit. Here, the distance unit refers to an actual distance corresponding to a unit distance on the map.
Suppose that the three objects deployed in the first space are an object a, an object B, and an object C, and are marked by an object marking terminal a ', an object marking terminal B ', and an object marking terminal C ', respectively. After the first terminal D enters the first space, the server 20 may calculate the following relative distance as: s (A ' B '), S (A ' C '), S (A ' D), S (B ' C '), S (B ' D), S (C ' D). Assuming that the minimum relative distance among the above relative distances is S (B 'C'), S (B 'C') can be taken as a distance unit. That is, when the object relative position map is drawn, the distance between the objects B and C is identified on the map using one distance unit.
After determining the distance cell, the corresponding length of the relative distance between other objects on the map may be calculated. For example, the length of the object a and the object B on the map is S (a ' B ')/S (B ' C '), and similarly, the length of the object a and the object C on the map is S (a ' C ')/S (B ' C '), the length of the object a and the first terminal D on the map is S (a ' D)/S (B ' C '), the length of the object B and the first terminal D on the map is S (B ' D)/S (B ' C '), and the length of the object C and the first terminal D on the map is S (C ' D)/S (B ' C '), as shown in fig. 3 a.
Optionally, when the server 20 detects that the first terminal and/or at least one object marker terminal in the first space moves, the updated relative position between the first terminal and each object marker terminal may be obtained based on the methods provided in the foregoing embodiments; and then, updating the object relative position map according to the updated relative position between the first terminal and each object marking terminal.
In this embodiment, the user may hold the first terminal to move in the first space, and as the user moves continuously, the object displayed by the first terminal changes relative to the position map. If the user finds the designated object mark terminal in the first space, the designated object mark terminal may be thought of to move, so as to quickly find the designated object mark terminal.
For example, in a typical application scenario, a user may quickly find a designation based on a map of the relative positions of objects corresponding to a first space. For example, a warehouse stores a plurality of goods, and each goods is bound with an object tag terminal. For example, item A corresponds to object marker terminal A ', and item B corresponds to object marker terminal B'. Based on this, when the user enters the warehouse, a request for viewing the goods a can be sent to the server 20 through the mobile phone. After receiving the request, the server 20 may obtain the relative position between the mobile phone of the user and each object mark terminal in the warehouse, then draw an object relative position map corresponding to the warehouse, and send the object relative position map corresponding to the warehouse to the mobile phone of the user for display. Based on the method, the user can determine the relative position of the A goods from the object relative position map corresponding to the warehouse, and then the A goods can be quickly found.
On the basis of the object relative position map generated in the above embodiments, the server 20 may monitor a plurality of object marker terminals in the first space.
Alternatively, in some exemplary embodiments, the server 20 may determine whether there is a target object marker terminal deviating from the set position range among the plurality of object marker terminals according to the relative positions among the plurality of object marker terminals; if yes, judging whether a wireless signal matched with the specified user identification exists in the wireless signals received by the target object marking terminal; if not, the first terminal is prompted that the object marked by the target object marking terminal is in an abnormal state.
In this embodiment, when each object tag terminal in the first space detects that the signal strength of the other object tag terminals received by the object tag terminal changes, the identifier and the signal strength of the changed object tag terminal may be sent to the server 20. It should be understood that when a position of an object marker terminal in the first space moves, it may detect a change in signal strength of the remaining plurality of object marker terminals, which may also detect a change in signal strength of the object marker terminal. Based on this, when receiving the identification identifier and the signal strength variation value reported by the object tag terminal in the first space, the server 20 may select the identification identifier with the highest reporting frequency from the received identification identifiers, and use the device corresponding to the identification identifier with the highest reporting frequency as the target object tag terminal that may deviate from the set position range.
When it is determined that the target tag terminal is likely to deviate from the set position range, the server 20 may continue to detect whether or not there is a wireless signal matching the specified user identifier among the wireless signals received by the target tag terminal. If the user exists, the user exists around the specified object mark terminal. The specified user identifier is registered in the server 20 in advance, so that the server 20 may consider the user corresponding to the specified user identifier as the user authorized to obtain the first space. In this case, the server 20 may determine that the change in the position of the object marked by the target object marking terminal is associated with the operation by the user. If the judgment is no, the first terminal is prompted that the object marked by the target object marking terminal is in an abnormal state. In this embodiment, mutual monitoring can be realized among the plurality of object marking terminals in the first space by using the relative position change characteristics of the object marking terminals and other devices, which is beneficial to reducing monitoring cost.
In this embodiment, when the user authorized by the first space enters the first space, the user can wear the identification device with him, and the identification device may include a communication component for sending a wireless signal to the outside for other devices to detect the wireless signal. Optionally, the identification device may be implemented as a mobile phone carried by the user or an electronic work card worn by the user. When the electronic work card is implemented, the electronic work card may be implemented by a display device such as a liquid crystal display, an LED (Light Emitting Diode) display, a plasma display, and an electronic tag, which is not limited in this embodiment.
For example, when the first space is implemented as a museum, the object tag terminal M1 ' detects a change in the intensity of the wireless signal transmitted from the object tag terminal N ', the object tag terminal M2 ' also detects a change in the intensity of the wireless signal transmitted from the object tag terminal N ', and the object tag terminal N ' detects a change in the signal intensity of the object tag terminal M1 ' and the object tag terminal M2 '. After the object marker terminal M1 ', the object marker terminal M2 ' and the object marker terminal N ' respectively send the detected position change and the identification to the server 20, the server 20 may determine that the frequency of reporting the identification of the object marker terminal N ' is the highest, and further may determine that the object marker terminal N ' may have an abnormality. Next, it is detected whether a user authorized by the museum exists around the object marker terminal N'. If the user authorized by the museum exists, the position of the object marked by the object marking terminal N' can be considered to move under the operation of the authorized user; if no user authorized by the museum exists, an alarm prompt can be sent to the first terminal to prompt that the object marked by the object marking terminal N' may be stolen.
Optionally, in other exemplary embodiments, the server 20 may obtain a motion trajectory of the object in the first space within a set time according to the relative positions of the plurality of object marking terminals; and if the motion trail of the specified object in the first space in the set time does not accord with the set activity rule, prompting that the specified object is in an abnormal state to the first terminal. The designated object may be one or more objects in the first space, which is not limited in this embodiment.
Alternatively, each object tag terminal of the plurality of object tag terminals may obtain the signal strength change of the other object tag terminals, and report the signal strength change to the server 20. The server 20 determines the activity track of each object marker terminal according to the received signal strength change. And then, judging whether the activity track of each object marking terminal accords with a set activity rule. For example, when the first space is implemented as a zoo and the object is implemented as an animal, the server 20 may determine whether a motion trajectory change of the object marking terminal for marking the animal within a set time conforms to an activity rule of the animal. For example, if the position of a target marker terminal is unchanged within 2 hours, it is considered that the animal marked by the target marker terminal has symptoms such as shock, illness, or death. If the motion track of an object marking terminal indicates that the object marking terminal flies away from other object marking terminals within 10 seconds, the animal marked by the object marking terminal can be considered to be captured by other beasts or has a run-away phenomenon, and the description is omitted.
It should be noted that, on the basis of the above embodiments, a plurality of positioning devices are also disposed in the first space, and each positioning device can broadcast its identification code outwards through a wireless signal. A terminal (such as a first terminal or an object marking terminal) in the first space can sense wireless signals sent by a plurality of positioning devices, and sends the sensed wireless signals and the signal strength thereof to a server so that the server can position the terminal.
Taking the first terminal as an example, after the first terminal sends the wireless signal sensed by the first terminal and the signal strength thereof to the server, the server can determine which positioning devices the first terminal senses according to the identification code included in the wireless signal, and calculate the relative distance between the first terminal and the positioning devices sensed by the first terminal according to the strength of the wireless signal. When the server calculates the relative distance between the first terminal and the plurality of positioning devices, the actual position of the first terminal in the first space can be determined by combining the deployment positions of the plurality of positioning devices in the first space.
Similarly, based on the plurality of positioning devices in the first space, the actual position of any object marker terminal in the first space may be calculated by using the above method, which is not described again. Further, based on the actual position of the first terminal in the first space and the actual position of any one of the object marker terminals in the first space, the direction of the object distribution map may be determined, and a pointer may be drawn on the object distribution map to correct the object distribution map. The beacon may indicate which direction on the object distribution map corresponds to north/south in the first space or indicate which direction on the object distribution map corresponds to east/west in the first space. Fig. 3b illustrates an alternative case where the beacon indicates the direction of the north gate of the first space, it being understood that the present embodiment includes but is not limited thereto.
