Accordingly, the information acquisition device provided in the embodiment of the present disclosure may also be set in the mobile terminal device 101 , 102 , or 103 , or in other terminal devices different from the mobile terminal device 101 , 102 , or 103 .

[0039] It should be understood that Figure 1 The number of mobile terminal devices, networks and servers in the embodiment is merely illustrative. Any number of terminal devices, networks and servers may be provided as required.

[0040] Figure 2 The flowchart of the information acquisition method according to the embodiment of the present disclosure is schematically shown.

[0041] like Figure 2 As shown, the method includes operations S210 to S240.

[0042] In operation S210 , a storage status of a target item is determined based on a storage location of the target item in a storage area and a preset item distribution rule of the storage area.

[0043] In operation S220, if the storage state is an abnormal state, a target path is determined in the area plan of the storage area so that the mobile terminal device can move to a target location corresponding to the storage location based on the target path.

[0044] In operation S230 , a relative angle between the target item and the mobile terminal device is determined based on the storage location and the device position of the mobile terminal device during movement.

[0045] In operation S240, the emission angle of the ray sent by the ray sending module on the mobile terminal device to the target item is adjusted based on the relative angle, so that when the mobile terminal device moves to the target position based on the target path, the item information of the target item can be obtained using the mobile terminal device based on the emission angle.

[0046] According to embodiments of the present disclosure, the target item may be an item ordered by a user. After the user places an order, the package will pass through multiple storage areas before being delivered to the user. The storage areas may be sorting centers or package storage sites. Each storage area has a corresponding preset item distribution rule. Specifically, the preset item distribution rule may be set based on the size of the item. The preset item distribution rule may store large items in one distribution area and small items in another, facilitating item management.

[0047] Figure 3 A schematic diagram of a target item's waybill in the information acquisition method according to an embodiment of the present disclosure is schematically shown.

[0048] According to the embodiments of the present disclosure, Figure 3 As shown, the target item has a corresponding shipping label attached to it, and the target item's item information can be obtained based on the shipping label. The item information includes the target item's package number, transportation method, and consignee and sender information. The transportation method can be a slide-cage vehicle.

[0049] According to the embodiments of the present disclosure, Figure 3 As shown, the face sheet of the target item has an additional radio frequency area 310 on the upper layer of the original face sheet. The paper of the radio frequency area 310 is two-layered, and no glue is applied in the interlayer, which is used to place the RFID (Radio Frequency Identification) tag. Holes are punched around the radio frequency area 310, and a thin rope is glued on, with a portion of the edge of the thin rope protruding. The RFID tag can be taken out by pulling the thin rope, thereby realizing the reuse of the RFID tag. By installing an RFID tag on the face sheet of the target item, the storage location of the target item can be obtained using a location reader installed in the storage area. Among them, the location reader can be an RFID reader.

[0050] According to an embodiment of the present disclosure, after obtaining the storage location of the target item in the storage area, the storage location is detected based on the preset item distribution rule to determine whether the target item is stored in the preset distribution area, thereby determining the storage status of the target item.

[0051] According to an embodiment of the present disclosure, if the storage status is abnormal, it indicates that the target item may be lost or not placed in the designated location. Therefore, it is necessary to move the mobile terminal device to the target location corresponding to the storage location to complete the search for the target item and obtain the item information of the target item. The target location can be the location of the storage location projected onto the ground of the storage area. During the movement of the mobile terminal device, it can be moved by an employee holding it or carried by a smart cart to complete the movement.

[0052] According to an embodiment of the present disclosure, the mobile terminal device may be a PDA (Personal Digital Assistant) device for obtaining the item information of the target item. The PDA device may be used to scan the shipping label on the target item to obtain the item information of the target item.

[0053] According to an embodiment of the present disclosure, when the storage state is abnormal, a regional plan view of the storage area is obtained. The regional plan view is a two-dimensional map of the storage area. The regional plan view includes the locations of obstacles, target items, location readers, and mobile terminal devices located in the storage area.

[0054] According to an embodiment of the present disclosure, a target path is planned based on the location of the target object and the location of the mobile terminal device in the area plan, allowing the mobile terminal device to move to the target location based on the target path. The device position of the mobile terminal device is acquired in real time during its movement, and the relative angle between the target object and the mobile terminal device is determined. For example, the target object is 30° east-southeast of the mobile terminal device. By calculating the relative angle, the target object's location can be accurately determined, thereby completing the search for the target object.

[0055] According to an embodiment of the present disclosure, as the mobile terminal device moves, a ray transmission module on the mobile terminal device transmits rays toward a target object based on a relative angle. If the relative angle changes, the ray transmission angle is adjusted to ensure that the rays can more accurately reach the target object.

[0056] According to an embodiment of the present disclosure, when the mobile terminal device moves to the target position based on the target path, the target item is determined from multiple items based on the emission angle of the ray, and the mobile terminal device is used to scan the waybill of the target item to obtain the item information of the target item.

[0057] According to the embodiments of the present disclosure, by determining the storage status of the target item, a target path is planned on the regional plan in the event of an abnormal storage status, thereby facilitating the search for the target item and obtaining the target item's item information. Since the relative angle between the target item and the mobile terminal device is determined in real time as the mobile terminal device moves toward the target location based on the target path, the location of the target item can be more intuitively determined in three dimensions, improving the efficiency of searching for the target item and enabling the timely acquisition of item information, effectively improving the efficiency of transporting the target item.

[0058] According to an embodiment of the present disclosure, the storage status of the target item is determined based on the storage position of the target item in the storage area and the preset item distribution rule of the storage area, including: determining the distribution area corresponding to the target item in the storage area based on the preset item distribution rule; comparing the storage position with the area coordinates of the distribution area to generate a comparison result; when the comparison result indicates that the storage position is within the distribution area, determining that the storage status of the target item is a normal state; when the comparison result indicates that the storage position is outside the distribution area, determining that the storage status of the target item is an abnormal state.

[0059] According to the embodiment of the present disclosure, the storage area includes multiple distribution areas, and the attribute information of the target item can be matched with the preset item distribution rules to determine the distribution area corresponding to the target item. For example, the storage area includes distribution area A and distribution area B, wherein the storage volume in distribution area A is greater than or equal to 1m 3 The storage volume of the package in distribution area B is less than 1m 3 Then, according to the volume information in the attribute information of the target item, the distribution area corresponding to the target item is determined in distribution area A and distribution area B.

[0060] According to an embodiment of the present disclosure, each distribution area may be rectangular or circular. Multiple area coordinates are obtained for each distribution area, where the area coordinates may be the coordinates of the area edge of the distribution area. The storage location is compared with the multiple area coordinates one by one to generate a comparison result.

[0061] According to an embodiment of the present disclosure, if the comparison results show that the coordinate lengths of multiple area coordinates are greater than the coordinate length of the storage location, it means that the storage location of the target item is within the distribution area, and the storage status of the target item is normal, which complies with the preset item distribution rules.

[0062] According to an embodiment of the present disclosure, if the comparison results show that there is a coordinate length among the coordinate lengths of multiple area coordinates that is smaller than the coordinate length of the storage location, it means that the storage location of the target item is outside the distribution area, and the storage status of the target item is abnormal and does not comply with the preset item distribution rules.

[0063] According to an embodiment of the present disclosure, the storage status of a target item is determined based on the storage location and the regional coordinates of the distribution area, so that the storage status can be determined more accurately and reasonably.

[0064] Figure 4 A schematic diagram schematically illustrates a storage area in an information acquisition method according to an embodiment of the present disclosure.

[0065] According to an embodiment of the present disclosure, a target path is determined in an area plan map of a storage area, including: determining actual positions of a plurality of position readers in the storage area, and a plurality of planar positions of the plurality of position readers corresponding to the actual positions in the area plan map; determining a planar storage position corresponding to the storage position and a planar initial position of a movable terminal device in the area plan map based on a position ratio between the actual position and the planar position; and determining a target path in the area plan map based on the planar storage position and the planar initial position using a breadth-first algorithm.

[0066] According to an embodiment of the present disclosure, the actual positions of multiple position readers in a storage area are determined, where the actual positions are three-dimensional coordinates (x1, y1, z1). Multiple planar positions corresponding to the actual positions of the multiple position readers in a plan view of the area are determined, where the planar positions are two-dimensional coordinates (a1, b1). The position ratio between the actual positions and the planar positions is determined. During the calculation process, the three-dimensional actual positions are first mapped to two-dimensional coordinates, and then the position ratio is determined based on the mapped coordinates. For example, the position ratio is: x1 / a1=y1 / b1.

[0067] According to an embodiment of the present disclosure, a plane storage location corresponding to a storage location is determined in a regional plan view according to a position ratio. In the determination process, the storage location is first mapped to a two-dimensional coordinate, and then the coordinate values ​​are multiplied by the position ratio to obtain the plane storage location. For example, if the storage location is (x2, y2, z2), the coordinates (x2, y2) are obtained after mapping the storage location, and the coordinate values ​​are multiplied by the position ratio to obtain the plane storage location. The above method is used to determine the initial planar position of the mobile terminal device in the area plan.

[0068] According to an embodiment of the present disclosure, a breadth-first algorithm is used to determine a target path in a regional plan view based on a plane storage position and a plane initial position. Figure 4As shown, the plan view of the storage area includes obstacles 410, target items 420, location readers 430, and mobile terminal devices 440. During path planning, the breadth-first algorithm can determine the shortest path while avoiding obstacles to improve movement efficiency.

[0069] Figure 5 The spatial rectangular coordinate system of the information acquisition method according to the embodiment of the present disclosure is schematically shown.

[0070] According to an embodiment of the present disclosure, the relative angle between the target object and the movable terminal device is determined based on the storage location and the device position of the movable terminal device during movement, including: establishing a spatial rectangular coordinate system with the device position as the coordinate origin; determining the relative distance between the device position and the storage location in different directions in the spatial rectangular coordinate system; and determining the relative angle of the target object relative to the movable terminal device based on the relative distance according to a reference direction determined based on the spatial rectangular coordinate system.

[0071] According to the embodiments of the present disclosure, since the mobile terminal device is constantly moving, the relative angle of the target object relative to the moving mobile terminal device needs to be determined in real time. Therefore, a spatial rectangular coordinate system is established with the device position as the coordinate origin.

[0072] According to the embodiments of the present disclosure, Figure 5 As shown in the figure, point a is the device location of the mobile terminal, and point d indicates the storage location of the target item. Assuming the device location is (x1, y1, z1) and the storage location is (x2, y2, z2), then the length of line segment ae is y2-y1; the length of line segment ae is x2-x1; the length of line segment dc is y2-y1; and the length of line segment ac is √((y2-y1)+(x2-x1))². Here, ae, dc, and ac are the relative distances between the device location and the storage location in different directions in the spatial rectangular coordinate system.

[0073] According to embodiments of the present disclosure, the relative angle of a target object relative to a mobile terminal device is determined based on the relative distance, using a reference direction determined based on a spatial rectangular coordinate system. The reference angle can be determined by comparing the y-axis to due south and the x-axis to due east. By establishing a spatial rectangular coordinate system to calculate relative angles, the calculation process is more convenient and the results are more accurate.

[0074] According to an embodiment of the present disclosure, according to a reference direction determined based on a spatial rectangular coordinate system, the relative angle of the target object with respect to the movable terminal device is determined based on the relative distance, including: determining a plurality of right triangles in the spatial rectangular coordinate system based on a storage location and a device location, wherein the side length of each right triangle is determined based on the relative distance; and determining the relative angle associated with the reference direction based on the plurality of right triangles and the side length of each right triangle using an inverse trigonometric function.

[0075] According to the embodiments of the present disclosure, Figure 5 As shown, based on the storage location and the device location, multiple right triangles are determined in a spatial rectangular coordinate system. Specifically, they include right triangle 510 and right triangle 520. The side length of right triangle 510 is determined based on the relative distances dc and ac. The side length of right triangle 520 is determined based on the relative distances ae and ac.

[0076] According to an embodiment of the present disclosure, the relative distance is calculated using inverse trigonometric functions. Specifically, Figure 5 As shown, ∠eac = arctan((x2-x1 / y2-y1)), and ∠dac = arctan((z2-z1) / √((y2-y1)+(x2-x1))²). This determines the relative angle to be arctan((x2-x1 / y2-y1))° east of south, and the vertical angle to be arctan((z2-z1) / √((y2-y1)+(x2-x1))²). Calculating the relative angle using inverse trigonometric functions makes the calculation process more convenient.

[0077] Figure 6 The following schematically shows a scenario diagram of adjusting the emission angle in the information acquisition method according to an embodiment of the present disclosure.

[0078] According to an embodiment of the present disclosure, the emission angle of rays sent by a ray sending module on a mobile terminal device to a target object is adjusted based on the relative angle, including: determining the ray sending position of the ray sending module based on the device position; in the case where the relative angle changes, determining the angle change difference and the angle change direction based on the changed relative angle; and adjusting the emission angle based on the angle change difference, the angle change direction and the ray sending position.

[0079] According to an embodiment of the present disclosure, an RFID tag and an infrared irradiation lamp are installed in a PDA. The RFID positioning device can calculate the horizontal and vertical angles of the cargo relative to the PDA, based on due south. The ray transmission module also adjusts the irradiation angle based on due south, thereby accurately locating the cargo. The ray transmission module can be an infrared irradiation device.

[0080] According to the embodiment of the present disclosure, the ray sending position of the ray sending module is the device position of the mobile terminal device. During the movement of the mobile terminal device, the ray sending position will change in real time. Because the device position will change, that is, the coordinates x, y, and z of the device position will change, so the calculated relative angle will also change. Figure 6 As shown in the figure, when the staff moves the mobile terminal device from point A to point B, the angle of the infrared light changes, but the final target is still cargo A.

[0081] According to the embodiments of the present disclosure, when the relative angle changes, the difference between the changed relative angle and the angle of change 2 is calculated to determine the angle change difference and the direction of the angle change. Based on the angle change difference, the angle change direction, and the ray transmission position, the emission angle is adjusted to accurately point the ray at the target object, facilitating the search for the target object.

[0082] Figure 7 The diagram schematically shows a schematic diagram of saving information in the information acquisition method according to an embodiment of the present disclosure.

[0083] According to an embodiment of the present disclosure, the information acquisition method also includes: based on a preset timing task, detecting the position of the target item in the storage area and generating detection data; determining the position of the mobile terminal device when a request for obtaining item information is received from the mobile terminal device; matching the position of the target item in the detection data with the position of the mobile terminal device to generate a matching result; and outputting the item information when the matching result indicates that the position of the target item and the position of the mobile terminal device are in the same distribution area in the storage area.

[0084] According to an embodiment of the present disclosure, based on a preset timed task, the location of a target item in a storage area is detected and detection data is generated. Specifically, the location of the target item can be read by an RFID position reader every minute and the read data can be saved.

[0085] like Figure 7 As shown, 1, 2, 3, and 4 represent the package numbers of four items. Every minute, the RFID location reader reads the location of all items in the storage space and saves the read data to Service A. For example, the location information of the item with package number 1 stored in Site A is saved to Service A.

[0086] According to an embodiment of the present disclosure, upon receiving a request for obtaining item information triggered by a worker operating a target item using a mobile terminal device, the location of the mobile terminal device is determined. The location of the mobile terminal device is matched with the location of the target item stored on Service A to determine whether the two are within the same distribution area.

[0087] According to the embodiments of the present disclosure, if the two devices are in the same distribution area, the operator's operation is normal and the target item's information can be provided. If they are not in the same distribution area, the operator is not in the distribution area where the target item is located, the operation fails, and the target item's information is not provided. By matching the location of the mobile terminal device with the location of the target item, fraudulent operations are reduced. Operations can no longer be performed based solely on the package number, but must rely on the physical object to facilitate the management of the target item.
