Fig. 1 is a flowchart of a method for positioning a device in cooperation with multidimensional information according to an embodiment of the present invention. The embodiment can be applied to the situation of carrying out multi-dimensional information co-location on equipment which is adjusted remotely. The method can be executed by a device positioning device with multi-dimensional information cooperation, the device can be realized in a software and/or hardware mode, and the device can be integrated on any electronic device with a network communication function. As shown in fig. 1, the method for locating a device by using multi-dimensional information cooperation provided in the embodiment of the present invention may include the following steps:
s110, when the target terminal equipment acquires the equipment identification information from the equipment to be positioned, the reference terminal equipment entering the preset distance range of the target terminal equipment is determined.
The terminal device may refer to a portable device having functions of scanning, positioning, storing, and the like, for example, the terminal device may be a smartphone. The target terminal device and the reference terminal device may be used to distinguish different terminal devices, and there is only one target terminal device, and there may be one or more reference terminal devices. In addition, the target terminal device and the reference terminal device can be terminal devices belonging to employees of the same company, so that information interaction between the target terminal device and the reference terminal device can be realized through communication software inside the company under the condition that communication connection is not established.
In this embodiment, the device to be positioned may refer to a device that needs to be positioned, for example, the device to be positioned may be a shooting device. The device identification information may refer to tag information related to an attribute of the device to be located, and may be unique identity information characterizing the device to be located, for example, the device identification may be device barcode information. The preset distance range may refer to a preset range of an interval region between the target terminal device and the preset distance range, and may be used to indicate a distance between the target terminal device and the preset distance range.
In this embodiment, the device barcode may be scanned by the target terminal device, so as to obtain device identification information, and store the device identification information. Meanwhile, all reference terminal devices within the preset distance range of the target terminal device are searched and obtained through the target terminal device. Wherein, the reference terminal device satisfying the condition can be one or more.
In an alternative of this embodiment, the size of the preset distance range of the target terminal device may be determined by a signal coverage range when the target terminal device sends a preset communication signal to a surrounding area; the preset communication signal comprises a Bluetooth signal and a radio frequency signal.
The preset communication signal may refer to a signal preset to indicate communication. Specifically, the default communication signal may include a bluetooth signal and a radio frequency signal. In this embodiment, the preset distance range of the target terminal device may be set according to the coverage of the bluetooth or radio frequency signal sent by the target terminal device to the surrounding area. That is, the signal coverage may be set as the preset distance range of the target terminal device, and the area outside the signal coverage is not within the preset distance range of the target terminal device. For example, if the bluetooth signal is used as the preset communication signal and the bluetooth transmission distance is at most 10 meters, the preset distance range may be set to be less than or equal to 10 meters away from the target terminal device.
By adopting the above manner, the preset distance range of the target terminal device is determined according to the preset communication signal coverage range sent by the target terminal device, so that the reference terminal device within the preset distance range of the target terminal device can be ensured to receive the preset communication signal sent by the target terminal device.
In an alternative of this embodiment, determining the reference terminal device entering the preset distance range of the target terminal device may include steps a1-a 2:
step A1, when the target terminal device moves to the interior of the building provided with the device to be positioned, determining the latest positioning information recorded when the target terminal device is stopped to the reference positioning state; the reference positioning state comprises a state that the positioning effectiveness of the target terminal equipment is gradually weakened to a state that the positioning requirement is not met.
And step A2, taking the positioning position indicated by the latest positioning information recorded when the reference positioning state is reached as the central position, and inquiring the terminal equipment entering the central position within the preset distance range as the reference terminal equipment.
The reference positioning state may be a state in which the positioning function of the reference terminal device is utilized to perform auxiliary positioning on the device to be positioned, and may be used to represent a critical state in which the positioning validity of the target terminal device is gradually reduced to a state in which the positioning is performed through the reference terminal device when the positioning validity of the target terminal device does not meet the positioning requirement. It can be understood that, in the process of moving the target terminal device to the inside of the building, the positioning signal gradually weakens until accurate positioning information cannot be acquired. When in the reference positioning state, the positioning effect of the reference terminal device is necessarily better than that of the target terminal, so that the reference terminal device can be used for auxiliary positioning.
In this embodiment, the closest positioning position of the target terminal device recorded when the target terminal device is in the reference positioning state may be used as the center position, a circular area with the center position as the center of a circle and a preset distance as the radius may be determined according to the preset distance range, and the terminal device in the circular area may be used as the reference terminal device. The reference terminal device may periodically report the self-positioning information to the management server.
By adopting the mode, the reference terminal equipment in the preset distance range can be determined according to the nearest positioning information when the reference positioning state is ended, and the equipment with better positioning effect can be used for positioning.
S120, determining the relative position information between the target terminal device and the reference terminal device in the current communication triggering stage; the positioning effectiveness of the reference terminal device in the current communication trigger phase is higher than that of the target terminal device in the current communication trigger phase.
The communication triggering phase may refer to a period when the reference terminal device is triggered by the target terminal device to keep the reference terminal device in the communication function on state. The inter-device relative position information may refer to information for characterizing a relative position between the target terminal device and the reference terminal device. Illustratively, the inter-device relative position information may include the distance, direction, communication signal strength, etc. of the reference terminal device relative to the target terminal device.
In this embodiment, the positioning validity may be used to indicate the effect of the positioning of the device. Specifically, the higher the positioning effectiveness, the better the positioning effect of the device can be shown. It can be understood that, when in the current communication triggering phase, the positioning effectiveness of the reference terminal device is higher than that of the target terminal device, so that the positioning effect of the reference terminal device is better at this time.
S130, determining the positioning information of the equipment to be positioned according to the relative position information between the equipment and the positioning information of the reference terminal equipment in the current communication triggering stage so as to be associated and managed with the corresponding equipment identification information.
In this embodiment, the positioning information of the device to be positioned may be obtained according to the relative position information between the devices and the positioning information of the reference terminal device in the current communication trigger stage. Illustratively, if the positioning information of the reference terminal device at the current communication triggering stage is acquired and the direction and distance of the reference terminal device relative to the target terminal device are known, the position of the target terminal device can be calculated, so as to accurately position the target terminal device. In the process of acquiring the device identification information by scanning the device to be positioned by using the target terminal device, because the target terminal device is closer to the device to be positioned, the position of the target terminal device can be roughly determined as the position of the device to be positioned, so that the rough positioning of the device to be positioned is realized, and the positioning information of the device to be positioned and the corresponding device identification information are subjected to associated management.
According to the technical scheme, the identification information of the device to be positioned can be scanned and stored through the target terminal device, the relative position information between the devices can be acquired through the reference terminal device, and then the device to be positioned can be positioned according to the relative position information between the devices and the positioning information of the reference terminal device in the current communication triggering stage, so that the multi-dimensional information co-positioning of the device to be positioned can be realized, the device to be positioned does not need to be embedded into a Beidou/GPS positioning chip, and low-cost positioning management is realized.
In an alternative of this embodiment, the method for locating a device by using multi-dimensional information cooperation provided in this embodiment of the present invention may further include:
and determining the moving track of the target terminal equipment from the acquisition of the equipment identification information to the current communication triggering stage through a magnetometer and a gyroscope which are built in the target terminal equipment.
Correspondingly, determining the positioning information of the equipment to be positioned according to the relative position information between the equipment and the positioning information of the reference terminal equipment in the current communication triggering stage, wherein the determining comprises the following steps:
and according to the relative position information among the devices, the movement track from the acquired device identification information to the current communication triggering stage and the positioning information of the reference terminal device in the current communication triggering stage.
In this embodiment, in the process of positioning the device to be positioned, the target terminal device and the reference terminal device may change their positions due to their own movement, and the change in the position of the target terminal device may affect the determination result of the reference terminal device within the preset distance range. Therefore, the moving track of the target terminal device between the scanning device identification and the current communication trigger stage can be obtained through the magnetometer and the gyroscope, and the moving track is taken as one of the parameters for determining the positioning information of the device to be positioned.
By adopting the mode, the movement track of the target terminal equipment between the stage of acquiring the equipment identification information and the current communication triggering stage is used as one of the factors for determining the positioning information of the equipment to be positioned, so that the positioning error caused by the position change of the target terminal equipment can be reduced, and the positioning accuracy can be improved to a certain extent.
Fig. 2 is a flowchart of a method for positioning a device in cooperation with multidimensional information according to an embodiment of the present invention. The present embodiment is optimized based on the above embodiments, and the embodiments of the present invention may be combined with various alternatives in one or more of the above embodiments. As shown in fig. 2, the method for locating a device by using multi-dimensional information cooperation provided in the embodiment of the present invention may include the following steps:
s210, when the target terminal equipment acquires the equipment identification information from the equipment to be positioned, determining the reference terminal equipment which enters the preset distance range of the target terminal equipment.
S220, controlling the target terminal device and the reference terminal device to perform communication attempt at the current communication triggering stage, and determining and recording the communication strength and the communication direction of the reference terminal device relative to the target terminal device under the communication triggering and communication connection state not established; the positioning effectiveness of the reference terminal device in the current communication trigger phase is higher than that of the target terminal device in the current communication trigger phase.
In this embodiment, the target terminal device may send a communication signal to trigger the reference terminal device to start the communication function, but does not establish an actual communication connection with the reference terminal device. In this case, the communication strength and the communication direction of the reference terminal device with respect to the target terminal device can be obtained. It can be understood that, because the positioning effectiveness of the target terminal device at the current communication triggering stage is poor, the accurate position of the target terminal device cannot be obtained, and thus the relative distance between the target terminal device and the reference terminal device cannot be determined.
In an alternative of this embodiment, controlling the target terminal device and the reference terminal device to perform a communication attempt at the current communication trigger stage, determining the communication strength and the communication direction of the reference terminal device relative to the target terminal device in the communication trigger state and the communication connection state is not established, may include steps B1-B2:
and step B1, sending communication trigger information to the reference terminal equipment at the current communication trigger stage, and indicating the reference terminal equipment to start the communication function.
Step B2, frequency hopping paging is carried out on the reference terminal equipment with the communication function started, and the communication intensity of the reference terminal equipment in the target communication state and the communication direction relative to the target terminal equipment are determined; wherein the target communication state comprises a state in which the reference terminal device scans for an external page to respond and a communication connection is not established.
In this embodiment, after querying the reference terminal device within the preset distance range of the target terminal device, the target terminal device may send a message to the reference terminal device through the company internal communication software to request to start the communication function of the reference terminal device. When the company internal communication software of the reference terminal device receives the request of the target terminal device, the reference terminal device can be driven to start the communication function, so that the reference terminal device works in the slave device slave mode.
And then the target terminal device pages the slave in a master role in a frequency hopping mode. The slave scans for external pages at regular intervals and responds to external pages when scanned. At this time, the target terminal device may formally search for the reference terminal device, but does not need to establish a communication connection with the reference terminal device. The target terminal device records the communication signal strength and the signal direction relative to the target terminal device, and simultaneously records the Beidou geographic position of the reference terminal device through company internal communication software.
If the number of the reference terminal devices is multiple, all the reference terminal devices are processed in the same way through the target terminal device, the communication signal strength and the signal direction relative to the target terminal device of all the reference terminal devices are recorded, and meanwhile, the Beidou geographic positions of the reference terminal devices are recorded through company internal communication software. At this time, the target terminal device does not try to calculate the distances between the target terminal device and all the reference terminal devices, and only uses all the reference terminal devices as a set to be associated with the scanned device to be positioned at the corresponding time. For example, when the mobile phone a discovers the mobile phones b1, b2 and b3 when scanning the device a, the set { b1, a2 and b3} is associated with the device a; when the mobile phone A discovers the mobile phones c1, c2 and c3 when scanning the device B, the set { c1, c2 and c3} is associated with the device B, and the associated information is formed into an association table.
By adopting the mode, the communication strength and the communication direction of the reference terminal equipment relative to the target terminal equipment can be obtained under the condition that the communication is triggered and the communication connection is not established, the distance between the reference terminal equipment and the target terminal equipment is not directly measured through the communication connection, and the complexity and the low accuracy of realizing the distance measurement through the communication connection are avoided.
And S230, determining the relative position information between the devices in the current communication triggering stage according to the communication strength and the communication direction of the reference terminal device relative to the target terminal device in the current communication triggering stage.
In this embodiment, by knowing the communication strength and the communication direction of the reference terminal device relative to the target terminal device in the current communication trigger phase, the relative position between the target terminal device and the reference terminal device in the current communication trigger phase can be determined.
In an alternative of this embodiment, before determining the inter-device relative location information in the current communication trigger phase according to the communication strength and the communication direction with respect to the target terminal device in the current communication trigger phase, the method may further include:
when the communication is triggered and the communication strength and the communication direction relative to the target terminal equipment in the current communication triggering stage are determined, the positioning information of the reference terminal equipment in the current communication triggering stage is synchronously determined and is in associated record with the communication strength and the communication direction relative to the target terminal equipment in the current communication triggering stage.
In this embodiment, the position of the reference terminal device in the current communication trigger phase may be obtained at the same time, and is associated with the communication strength and the communication direction of the reference terminal device and the target terminal device in the current communication trigger phase.
S240, according to the relative position information among the devices and the positioning information of the reference terminal device in the current communication triggering stage, determining the positioning information of the device to be positioned so as to be associated and managed with the corresponding device identification information.
According to the technical scheme provided by the embodiment of the application, the communication strength and the communication direction of the reference terminal equipment relative to the target terminal equipment under the communication triggering state and the communication connection state are obtained, the relative position information between the equipment at the current communication triggering stage is determined, the reference terminal equipment with high positioning effectiveness is adopted for auxiliary positioning, the multi-dimensional information co-positioning of the equipment to be positioned is realized, the equipment to be positioned is not required to be embedded into a Beidou/GPS positioning chip, and the low-cost positioning management is realized.
Fig. 3 is a flowchart of another method for positioning a device in cooperation with multidimensional information according to an embodiment of the present invention. The present embodiment is optimized based on the above embodiments, and the embodiments of the present invention may be combined with various alternatives in one or more of the above embodiments. As shown in fig. 3, the method for locating a device by using multi-dimensional information cooperation provided in the embodiment of the present invention may include the following steps:
s310, when the target terminal equipment acquires the equipment identification information from the equipment to be positioned, the reference terminal equipment entering the preset distance range of the target terminal equipment is determined.
S320, controlling the target terminal device and the reference terminal device to perform communication attempt at the current communication triggering stage, and determining and recording the communication strength and the communication direction of the reference terminal device relative to the target terminal device under the communication triggering and communication connection state not established; the positioning effectiveness of the reference terminal device in the current communication trigger phase is higher than that of the target terminal device in the current communication trigger phase.
S330, when the positioning effectiveness of the target terminal equipment is detected to be recovered and meet the positioning requirement, whether the reference terminal equipment enters the preset distance range of the target terminal equipment again is determined.
In this embodiment, the Beidou signal of the target terminal device can be paid attention to by company internal communication software at all times, and when the Beidou signal is found again in the moving process of the target terminal device, the management server is searched to determine whether the reference terminal device appears again in the preset distance range of the target terminal device. It can be understood that when the positioning effectiveness of the target terminal device is recovered to meet the positioning requirement, the target terminal device can be accurately positioned.
And S340, if the reference terminal device is detected to enter the preset distance range of the target terminal device again, controlling the target terminal device and the reference terminal device to continuously perform communication attempt at the next communication trigger stage, and continuously detecting the communication intensity change condition of the reference terminal device relative to the target terminal device.
The next communication triggering phase may refer to a period when the reference terminal device is triggered again by the target terminal device after the current communication triggering phase and the reference terminal device maintains the communication function on state. In this embodiment, after the target terminal device triggers the reference terminal device to start the communication function, the change in the communication signal strength of the reference terminal device relative to the target terminal device may be continuously detected, and the change in the communication signal strength may be recorded.
S350, when the communication intensity is detected to be changed to be the same as the communication intensity recorded in the current communication triggering stage in the next communication triggering stage, determining the relative position information between the devices in the current communication triggering stage according to the relative distance between the reference terminal device and the target terminal device in the next communication triggering stage and the communication direction between the reference terminal device and the target terminal device in the current communication triggering stage.
In this embodiment, when it is detected that the reference terminal device enters the preset distance range of the target terminal device again, it may be determined whether the reference terminal devices in the next communication trigger phase and the current communication trigger phase are the same terminal device according to the communication intensity change. It will be appreciated that the reference terminal device may move from time to time, the communication signal strength becoming weaker as it moves away from the target terminal device and stronger as it moves closer to the target terminal device. Therefore, if the communication strengths of the reference terminal devices in the two communication triggering phases are the same, the reference terminal devices in the two phases can be determined to be the same terminal device.
When the reference terminal devices in the two communication triggering stages are determined to be the same terminal device, the relative distance between the target terminal device and the reference terminal device can be calculated according to the accurate positioning of the target terminal device and the reference terminal device, and then the relative position information between the devices in the current communication triggering stages can be obtained according to the relative distance and the communication direction of the reference terminal device relative to the target terminal device.
S360, according to the relative position information among the devices and the positioning information of the reference terminal device in the current communication triggering stage, determining the positioning information of the device to be positioned so as to be associated and managed with the corresponding device identification information.
According to the technical scheme provided by the embodiment of the application, when the positioning effectiveness of the target terminal equipment is recovered and meets the positioning requirement, the relative distance between the reference terminal equipment and the target terminal equipment is determined through the next communication trigger stage, the relative position information between the equipment in the current communication trigger stage is obtained by combining the communication strength and the communication direction of the reference terminal equipment relative to the target terminal equipment, which are obtained in the current communication trigger stage, the positioning information of the equipment to be positioned is finally determined, the multi-dimensional information cooperative positioning of the equipment to be positioned is realized by combining the information in the two stages, the equipment to be positioned does not need to be embedded into a Beidou/GPS positioning chip, and therefore low-cost positioning management is realized.

The embodiment can be applied to the situation of carrying out multi-dimensional information co-location on equipment which is adjusted remotely. The device can be implemented in software and/or hardware, and can be integrated on any electronic equipment with network communication function.
