It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

Before the technical scheme of the application is introduced, the following description is made on the relevant knowledge of the technical scheme of the application:
the UWB technology is a wireless carrier communication technology, which does not adopt a sine carrier, but utilizes non-sine wave narrow pulses of nanosecond level to transmit data, so that the occupied frequency spectrum range is very wide, and the UWB technology is particularly suitable for high-speed wireless access in indoor and other dense multipath places.
The following describes the inventive concept of the technical scheme of the application:
as described above, the prior art proposes a scheme of wearing UWB tags for each material to achieve high-precision positioning of the material. However, on one hand, the prior art will cause the problem of excessive material positioning cost due to the huge variety and quantity of materials and the need for charging UWB tags; on the other hand, since the UWB tag has a certain volume, the UWB tag cannot be generally worn on materials with high volume requirements, and thus positioning of such materials cannot be achieved.
In order to solve the technical problem, in the application, a UWB label is not required to be worn for each material, a material manager wears a UWB terminal, such as a UWB waffle or a UWB wristwatch, and the like, the material manager can scan the material through a scanning device, the position of the UWB terminal worn by the material manager is considered to be the position of the material when the material manager scans the material, based on the principle, the material management server can determine the material scanning time, determine the UWB terminal corresponding to the material scanning device which scans the material, determine the position information of the UWB terminal at the positioning time closest to the scanning time, and finally position the material according to the position information of the UWB terminal at the positioning time.
It should be understood that the technical solution of the present application can be applied to the following scenarios, but is not limited thereto:
exemplary, fig. 1 is an application scenario diagram provided in an embodiment of the present application, where, as shown in fig. 1, the application scenario relates to the following devices: a UWB terminal 110 worn by a material manager, a base station 120, a positioning server 130, a material management server 140, and a scanning device 150.
Alternatively, the UWB terminal 110 may be a UWB cradling or UWB wristwatch of a material manager, etc., and the UWB terminal 110 may transmit UWB positioning signals, i.e., wireless signals, around that may be used to position the UWB terminal 110. Of course, the UWB terminal 110 may also be a mobile phone or other wearable devices, such as smart glasses, smart gloves, smart clothes, smart shoes, smart bracelets, or smart jewelry, as long as the UWB terminal 110 specifically transmits a UWB positioning signal, and the form of the UWB terminal 110 is not limited by the present application.
Alternatively, the base station 120, which may be referred to as a UWB base station because it may receive the UWB positioning signal, may determine measurement data such as at least one of an arrival time, an arrival angle, and a signal strength of the UWB positioning signal. The base station 120 may be a base station (Base Transceiver Station, BTS), a base station (NodeB, NB), an evolved base station (Evolutional Node B, eNB), or a gNB, etc., which is not limited in this aspect of the present application.
Alternatively, the positioning server 130 may receive the measurement data transmitted from the base station 120, run a positioning algorithm to determine the position information of the UWB terminal 110 at each positioning time, and transmit the position information of the UWB terminal 110 at each positioning time to the material management server 140.
Alternatively, the location server 130 may be a separate physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server that provides a cloud computing service.
Optionally, the code scanning device 150 may be a code scanning gun or a self-service code scanning machine, which limits the application, the code scanning device 150 may perform code scanning identification on one-dimensional codes, two-dimensional codes or radio frequency identification (Radio Frequency Identification, RFID) identifiers on the materials, and further, the code scanning device 150 may report the code scanning time of the materials to the material management server 140, and may report the identifiers of the materials to the material management server 140.
Optionally, the material management server 140 may determine the code scanning time of the material, determine the UWB terminal corresponding to the code scanning device for scanning the code of the material, determine the position information of the UWB terminal at the positioning time closest to the code scanning time, and finally position the material according to the position information of the UWB terminal at the positioning time. In addition, the material management server 140 may store an identification of each material, and may also store location information of each material.
Alternatively, the material management server 140 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server that provides cloud computing services.
It should be understood that fig. 1 illustrates one UWB terminal, one base station, one location server, one material management server, and one scanning device, and in fact, the scenario may include other numbers of terminal devices, base stations, location servers, material management servers, and scanning devices, which the present application is not limited to.
The technical scheme of the application will be described in detail as follows:
fig. 2 is an interactive flowchart of a material positioning method according to an embodiment of the present application, where network elements involved in the method include: the materials management server and the positioning server, as shown in fig. 2, the method may include:
s210: the material management server obtains the code scanning time of the code scanning equipment on the target material;
s220: the positioning server acquires the position information of the UWB terminal corresponding to the code scanning equipment on the target positioning time;
s230: the positioning server sends the position information of the UWB terminal on the target positioning time to the material management server;
S240: and the material management server positions the target material according to the position information of the UWB terminal on the target positioning time.
Alternatively, in the present application, the materials may be files, routers, switches, etc., which the present application is not limited to.
Optionally, the code scanning device may send the code scanning time of the target material to the material management server in real time, where the target material may be any material to be located, and the application is not limited thereto.
Alternatively, the code scanning device may send the code scanning time of the target material to the material management server in a direct manner or an indirect manner. For example: after the code scanning equipment obtains the code scanning time of the target material, the code scanning time can be directly sent to the material management server. Or after the code scanning equipment acquires the code scanning time of the target material, the code scanning time can be sent to the equipment A, and then the equipment A forwards the code scanning time to the material management server.
Optionally, the code scanning device may actively send the code scanning time of the target material to the material management server, or may passively send the code scanning time of the target material to the material management server, for example: the code scanning device responds to the request message after receiving the request message sent by the material management server, so as to send the code scanning time of the target material to the material management server.
It should be understood that, in the case that there are a plurality of code scanning devices and a plurality of materials, the code scanning device needs to report, in addition to the code scanning time of the target material, the identification of the scanning device that scans the target material and the identification of the target material, so that the material management server determines which scanning device scans which material.
Alternatively, the identifier of the target material may be a one-dimensional code, a two-dimensional code, or an RFID identifier on the target material. The identification of the target material is attached when the target material leaves the factory, and is uniquely bound with the target material, wherein the identification of the target material is bound with various information of the target material, such as archiving time, archivers and the like, in other words, various information of the target material can be determined based on the identification of the target material and the binding relationship.
It should be understood that, when a certain UWB terminal is worn by a certain material manager, a code of a target material may be scanned by a certain scanning device, and in this case, the UWB terminal and the scanning device that are worn by the material manager at the same time may be referred to as a UWB terminal and a scanning device that have a corresponding relationship.
It should be appreciated that since the UWB positioning signal is a periodic nanosecond wireless pulse signal, the base station may derive at least one positioning time of the UWB terminal based on the periodic nanosecond wireless pulse signal, for example: the base station may locate the UWB terminal at times T1, t1+ T, T1+2t … …. And the target positioning time is the positioning time closest to the code scanning time in at least one positioning time of the UWB terminal. For example: the code scanning time of the code scanning equipment on the target material is T1, the positioning time of the UWB terminal corresponding to the code scanning equipment is T1, T1+ T, T1+2T … …, the code scanning equipment determines that the positioning time closest to the code scanning time of the target material is T1, and the T1 is the target positioning time.
If there are two positioning times closest to the code scanning time in at least one positioning time of the UWB terminal, either one of the two positioning times may be selected as the target positioning time. For example: the code scanning time of the code scanning equipment on the target material is T1+T/2, the positioning time of the UWB terminal corresponding to the code scanning equipment is T1, T1+ T, T1+2T … …, the code scanning equipment determines that the positioning time closest to the code scanning time of the target material is T1 and T1+T, and then the T1 or the T1+T can be used as the target positioning time. Alternatively, if there are two positioning times closest to the code scanning time in at least one positioning time of the UWB terminal, a positioning time preceding the two positioning times may be selected as the target positioning time. For example: the code scanning time of the code scanning equipment on the target material is T1+T/2, the positioning time of the UWB terminal corresponding to the code scanning equipment is T1, T1+ T, T1+2T … …, and the code scanning equipment determines that the positioning time closest to the code scanning time of the target material is T1 and T1+T, and then the T1 can be used as the target positioning time. Or if at least one positioning time of the UWB terminal has two positioning times closest to the code scanning time, the latter positioning time of the two positioning times can be selected as the target positioning time. For example: the code scanning time of the code scanning equipment on the target material is T1+T/2, the positioning time of the UWB terminal corresponding to the code scanning equipment is T1, T1+ T, T1+2T … …, the code scanning equipment determines that the positioning time closest to the code scanning time of the target material is T1 and T1+T, and the T1+T can be used as the target positioning time.
Alternatively, the position information of the UWB terminal at the target positioning time may be position information that is not determined in conjunction with a map, for example, longitude and latitude information of the UWB terminal at the target positioning time or three-dimensional coordinates under a three-dimensional coordinate system. Alternatively, the position information of the UWB terminal at the target positioning time may be position information determined in conjunction with a map, for example, the position information of the UWB terminal at the target positioning time may be a north door of a school.
Alternatively, the base station may receive the UWB positioning signal transmitted by the UWB terminal, and may determine measurement data such as at least one of the arrival time, the arrival angle, and the signal strength of the UWB positioning signal, which may transmit the measurement data to the positioning server, which determines the position of the UWB terminal based on the measurement data. The positioning server may determine the position of the UWB terminal according to the following positioning method, but is not limited thereto:
mode 1, approximate positioning method.
If the UWB terminal can only search for one base station, the positioning server can approximately calculate the position of the UWB terminal according to the angle of arrival (AoA), time of arrival (ToA) and signal strength of the UWB positioning signal transmitted by the UWB terminal, which is actually the most common positioning method in the 2nd generation (2nd Generation,2G) communication system.
Mode 2, trilateration positioning mode.
This approach requires three base stations, and then the arrival times of the UWB positioning signals to the three base stations, respectively, calculate the distances of the UWB terminal from the three base stations, and further, determine the position of the UWB terminal based on the distances of the UWB terminal from the three base stations.
Mode 3, triangulation positioning mode.
In this way, three base stations are required, then the distances between the UWB terminal and the three base stations are calculated from the arrival angles of the UWB positioning signals to the three base stations, and further, the position of the UWB terminal is determined based on the distances between the UWB terminal and the three base stations.
It should be noted that, the position of the UWB terminal obtained by the positioning server through the positioning method is longitude and latitude information of the UWB terminal or a three-dimensional coordinate under a certain three-dimensional coordinate system, and further, the positioning server may determine a specific position of the UWB terminal in combination with the current map, for example, determine that the UWB terminal is located at a north door of a school.
Optionally, the identifier of the current map used by the positioning server may be obtained from a base station or other devices, or the positioning server may pre-store a plurality of maps, and further, may determine the identifier of the corresponding current map according to longitude and latitude information of the UWB terminal or three-dimensional coordinates under a certain three-dimensional coordinate system.
Alternatively, the positioning server may actively or passively transmit the position information of the UWB terminal at the target positioning time to the asset management server. For example: the positioning server may periodically send the material management server information of the position of the UWB terminal at least one positioning time, including the target positioning time. Wherein the positioning server may periodically send the material management server the position information of the UWB terminal at the at least one positioning time because the position information of the UWB terminal is determined based on the periodic UWB positioning signals. For another example: the material management server may send a location request message to the location server, the location request message requesting to acquire location information of the UWB terminal at the target location time, the location request message may include: the code scanning time.
Optionally, the positioning request message further comprises at least one of: identification of code scanning equipment and a time difference threshold; the identification of the code scanning equipment corresponds to the identification of the UWB terminal; if the absolute value of the time difference between the target positioning time and the code scanning time of the UWB terminal is smaller than or equal to the time difference threshold value, the target positioning time is effective.
It should be understood that the material management server can determine the UWB terminal corresponding to the code scanning device through the acquired identification of the code scanning device.
It should be understood that if the time difference threshold is in the positioning request message, only if the target positioning time is determined to be valid based on the time difference threshold, the position information of the UWB terminal at the target positioning time may be taken as the position information of the target material. For example: assuming that the time difference threshold included in the positioning request message is 2s, and the time difference between the scanning time of the scanning device on the target material and the target positioning time is 1s, the material management server determines that the target positioning time is effective, and in this case, the material management server may use the position information of the UWB terminal on the target positioning time as the position information of the target material. For another example: assuming that the time difference threshold included in the positioning request message is 2s, and the time difference between the scanning time of the scanning device on the target material and the target positioning time is 3s, the material management server determines that the target positioning time is invalid, and in this case, the material management server cannot take the position information of the UWB terminal on the target positioning time as the position information of the target material.
It should be understood that if the time difference threshold is not included in the positioning request message, the target positioning time does not involve validity or invalidity, and the material management server may directly use the position information of the UWB terminal at the target positioning time as the position information of the target material. For example: the code scanning time of the code scanning equipment on the target material is 10 points, zero and 1 second, and the positioning time of the UWB terminal comprises: based on the 10 th zero 2 seconds, the 10 th zero 12 seconds, and the 10 th zero 22 seconds … …, it can be determined that the target positioning time is 10 th zero 2 seconds, and the material management server can use the position information of the UWB terminal at the target positioning time as the position information of the target material.
It should be understood that, in the case that the positioning server actively sends the position information of the UWB terminal at the target positioning time to the material management server, the material management server may also obtain the above time difference threshold, determine whether the target timer is valid based on the time difference threshold, and further, when the target positioning time is determined to be valid based on the time difference threshold, the material management server may use the position information of the UWB terminal at the target positioning time as the position information of the target material. The material management server may pre-store the time difference threshold, or the material management server may obtain the time difference threshold from the base station, the positioning server, or other devices.
Alternatively, the asset management server may receive a positioning response message sent by the positioning server, where the positioning response message is used to determine the position information of the UWB terminal at the target positioning time. It may include: position information of the UWB terminal at the target positioning time.
Optionally, the positioning response message further comprises at least one of: the method comprises the steps of target positioning time, identification of a UWB terminal, identification of a map used by the UWB terminal when the target positioning time is positioned, and time difference between the target positioning time and code scanning time.
The target positioning time corresponds to the position information of the UWB terminal on the target positioning time, and the positioning response message carries the identification purpose of a map used by the UWB terminal when the target positioning time is positioned, wherein the identification purpose is as follows: the material management server can determine the specific position of the UWB terminal according to the longitude and latitude information of the UWB terminal or the three-dimensional coordinates under a certain three-dimensional coordinate system and the map, so that the specific position of the target material is determined. The purpose of the positioning response message carrying the time difference between the target positioning time and the code scanning time is as follows: the material management server can determine whether the target timer is valid according to the time difference and the time difference threshold, and further, when the target positioning time is determined to be valid based on the time difference threshold, the material management server can take the position information of the UWB terminal on the target positioning time as the position information of the target material. Of course, the positioning response message may not need to carry the time difference between the target positioning time and the code scanning time, because the material management server itself may obtain the code scanning time of the code scanning device on the target material from the code scanning device, and may also obtain the target positioning time from the positioning server, based on which the material management server may calculate the time difference between the target positioning time and the code scanning time.
It should be noted that, the technical scheme provided by the application can support one or more material managers to check materials, and only the code scanning equipment and the UWB terminal are bound one by one.
It should be appreciated that for the case where the positioning server actively transmits the position information of the UWB terminal at the target positioning time to the material management server, the positioning server may periodically transmit positioning response messages to the material management server, each of which is a positioning response message at the positioning time, which may include: the UWB terminal's location information at the location time. Further, the method may further include: the positioning time, the identification of the UWB terminal, the identification of the map used by the UWB terminal when positioning the positioning time, and the time difference between the positioning time and the code scanning time. And the material management server determines the target positioning time by itself after acquiring the positioning response messages, and positions the target material according to the position information of the UWB terminal at the target positioning time.
The technical scheme of the application is exemplarily illustrated by the following two specific examples:
example 1, fig. 3 is an interaction flow chart of another material positioning method according to an embodiment of the present application, where a network element involved in the method includes: the method may include, as shown in fig. 3, UWB terminals, base stations, positioning servers, material management servers, and code scanning devices:
S310: the UWB terminal sends UWB positioning signals to the base station;
s320: the base station determining measurement data regarding the UWB positioning signal;
