[0058] In the item taking scenario, the terminal device 110 interacts with the storage cabinet 120.

[0059] In some cases (for example, acquiring a target marker frequency or acquiring a mapping relationship between each area and the marker frequency, uploading the item taking confirmation information and the item taking confirmation instruction to the server, etc.), the terminal device 110 and the storage cabinet 120 also need to interact with the server 130 (for example, acquiring the target ultrasonic carrier frequency band corresponding to the storage cabinet from the server, uploading the slot item taking completion state to the server, etc.).

In the first embodiment, only the overall description of the system architecture is described, and the description will not be repeated.

[0061] The second exemplary embodiment of the present disclosure provides a method for taking an item.

[0062] Figure 2A flowchart of a pickup method applied to a terminal device according to an embodiment of the present disclosure is shown schematically.

[0063] Referring to Figure 2 The pickup method applied to a terminal device provided by the embodiment of the present disclosure includes the following steps: S210, S220, S230 and S240.

[0064] In step S210, the positioning information of the terminal device is acquired.

[0065] According to the embodiment of the present disclosure, the positioning information is used to distinguish different areas where the terminal device is located, and the corresponding marker frequency of different areas is different. The area can be a province, a city, a division area of a province and a city (such as different business circles, different logistics areas, etc.), and various fine granularities, and the range of different areas can be defined according to the division requirements of the actual scene. For example, the marker frequency corresponding to Beijing area and Tianjin area is different. Or, the marker frequency corresponding to Beijing Haidian District and Beijing Chaoyang District is different.

[0066] In step S220, the target marker frequency matching the positioning information is acquired.

[0067] In some embodiments, the mapping relationship between each area and the marker frequency is obtained by pre-configuration on the server side and can be dynamically updated.

[0068] In some embodiments, in step S220, the target marker frequency matching the positioning information is acquired, including: acquiring the mapping relationship between each area and the marker frequency from the server or from the local terminal device; determining the target marker frequency corresponding to the target area indicated by the positioning information according to the mapping relationship; or sending a marker frequency acquisition request to the server based on the positioning information; receiving the target marker frequency matching the positioning information fed back by the server.

[0069] The terminal device 110 can pre-acquire the mapping relationship between each area and the marker frequency from the server 130 and store it locally; in the case that the server 130 has a mapping relationship update, the mapping relationship can be updated locally by a synchronous update or a lagging update.

[0070] In some implementation scenarios, when the terminal device 110 picks up, the terminal device 110 can acquire the mapping relationship locally or acquire the latest mapping relationship from the server 130. Then the terminal device 110 determines the target marker frequency corresponding to the target area indicated by the positioning information according to the mapping relationship.

[0071] In some implementation scenarios, the terminal device 110 sends a flag frequency acquisition request to the server 130 based on the positioning information when picking up the item. After receiving the flag frequency acquisition request, the server 130 determines a target flag frequency matching the positioning information according to the mapping relationship between each region and the flag frequency, and sends the target flag frequency to the terminal device.

[0072] In step S230, an item pickup ultrasonic carrier signal is generated according to the locker identifier corresponding to the item to be picked up, the item pickup code information, and the target flag frequency.

[0073] Figure 3 A detailed implementation flowchart of step S230 according to an embodiment of the present disclosure is schematically shown.

[0074] Referring to Figure 3 According to an embodiment of the present disclosure, in step S230, an item pickup ultrasonic carrier signal is generated according to the locker identifier corresponding to the item to be picked up, the item pickup code information, and the target flag frequency, which includes the following steps: S310, S320, S330, and S340.

[0075] In step S310, target ultrasonic carrier information corresponding to the item to be picked up is acquired. The target ultrasonic carrier information includes a target ultrasonic carrier frequency band, a target ultrasonic amplitude, or a target ultrasonic power.

[0076] In some embodiments, in step S310, the target ultrasonic carrier information corresponding to the item to be picked up is acquired by acquiring the target ultrasonic carrier information corresponding to the item to be picked up from the server.

[0077] The target ultrasonic carrier information for different lockers in the same region is the same or different.

[0078] In the case that the distance between different cabinets in the same area is far, different cabinets in the same area can have the same target ultrasonic carrier information. In the case that multiple people take out the items at the same time, for example, there are two cabinets A and B in the same room, and three people P1, P2 and P3 use terminal devices to take out the items respectively, P1 wants to take out the compartment G1 in the cabinet A, P2 wants to take out the compartment G2 in the cabinet A, and P3 wants to take out the compartment G3 in the cabinet B; since the cabinets A and B correspond to the same target ultrasonic carrier information, the target ultrasonic carrier frequency band used for coding, the modulated target ultrasonic amplitude or power, and the target marker frequency in the three types of information to be carried are the same (corresponding to the same area), and at least one of the cabinet identifier and the taking-out code information corresponding to the taking-out item has a difference; the cabinets A or B will simultaneously receive three taking-out ultrasonic carrier signals (the receiving time may have a sequence or the receiving time of multiple signals may coincide in some individual cases), and after the cabinets A and B respectively decode the received signals, the difference information (for example, the difference of the cabinet identifier and the taking-out code information) can be used to distinguish whether the taking-out instruction is for itself or for other cabinets; or to distinguish which taking-out instruction is for the storage compartments of itself. However, in this way, if the taking-out ultrasonic carrier signals have a time sequence, in the case that a cabinet receives multiple taking-out ultrasonic carrier signals sent to itself and other cabinets in the vicinity at the same time, the interference between the taking-out ultrasonic carrier signals is relatively small; however, sometimes multiple taking-out ultrasonic carrier signals are received at the same time, and the interference between the taking-out ultrasonic carrier signals is large, which affects the analysis and decoding process.

[0079] Therefore, embodiments of the present disclosure provide a solution that the target ultrasonic carrier information of different cabinets in the same area is different.

[0080] In the case that the target ultrasonic carrier information of different cabinets in the same area is different, the target ultrasonic carrier information is used to distinguish different cabinets in the same area in at least one dimension of amplitude or frequency, and the target ultrasonic carrier information is generated by the server according to the cabinet distribution information in the area where the taking-out item is located, and is used to distinguish different cabinets in the same area.

[0081] Alternatively, in some embodiments, in the step S310, the target ultrasonic carrier information corresponding to the taking-out item is obtained, including: receiving the target ultrasonic carrier information selected by the user in the presented ultrasonic carrier option, and synchronizing the selected target ultrasonic carrier information to the server. In some embodiments, the target ultrasonic carrier information of different cabinets in the same area is the same or different.

[0082] In the case that the target ultrasonic carrier information of different cabinets in the same area is different, the target ultrasonic carrier information is used to distinguish different cabinets in the same area in at least one dimension of amplitude or frequency, the ultrasonic carrier option includes at least one ultrasonic carrier information, the ultrasonic carrier option is associated with the positioning information and dynamically updated according to the selection of the user in the same area, and different ultrasonic carrier information is used to distinguish different cabinets in the same area.

[0083] For example, there are two cabinets A, B and C in the same area, and there are three different target ultrasonic carrier information Z1, Z2 and Z3 corresponding to the three cabinets; when there is no cabinet to pick up, the corresponding relationship between each cabinet and the target ultrasonic carrier information is uncertain. Assuming that cabinet A has a user P1 to pick up, the ultrasonic carrier option presented on the terminal device of user P1 at this time will be Z1, Z2 and Z3, user P1 selects target ultrasonic carrier information Z1, and the terminal device of user P1 synchronizes the selection information of user P1 selecting target ultrasonic carrier information Z1 to the server; then the server establishes the binding relationship between cabinet A and target ultrasonic carrier information Z1; and updates the ultrasonic carrier option to available options: Z2 and Z3. Then assume that cabinet B has a user P3 to pick up, the ultrasonic carrier option presented on the terminal device of user P3 at this time will be Z2 and Z3, user P3 selects target ultrasonic carrier information Z2, and the terminal device of user P3 synchronizes the selection information of user P3 selecting target ultrasonic carrier information Z2 to the server; then the server establishes the binding relationship between cabinet B and target ultrasonic carrier information Z2; and updates the ultrasonic carrier option to available options: Z3. Then assume that cabinet C has a user P4 to pick up, the ultrasonic carrier option presented on the terminal device of user P4 at this time will be Z3, user P3 selects target ultrasonic carrier information Z3, and the terminal device of user P4 synchronizes the selection information of user P4 selecting target ultrasonic carrier information Z3 to the server.

[0084] By setting the ultrasonic carrier option, the binding of each cabinet in the same area and the target ultrasonic carrier information is not preformed, but the user selects the desired target ultrasonic carrier information during the pick-up process and realizes the binding of the cabinet and the corresponding target ultrasonic carrier information, which provides the user with the selection right and improves the interest of the user in picking up.

[0085] In step S320, according to the above target ultrasonic carrier frequency band, the cabinet identifier and the pick-up code information corresponding to the to-be-picked item are encoded respectively, and the first encoding sequence and the second encoding sequence are obtained correspondingly.

[0086] According to an embodiment of the present disclosure, in the step S320, the locker identifier corresponding to the to-be-taken item and the taking code information are encoded according to the target ultrasonic carrier frequency band, to obtain a first encoded sequence and a second encoded sequence, including: parsing the locker identifier in which the to-be-taken item is located into a first string corresponding to a preset radix; parsing the taking code information into a second string corresponding to the preset radix; encoding the first string and the second string according to an encoding frequency in the target ultrasonic carrier frequency band for encoding characters of the preset radix, to obtain the first encoded sequence and the second encoded sequence; the encoding frequencies corresponding to different characters of the preset radix have a preset frequency interval.

[0087] In some embodiments, the hexadecimal is taken as an example of the preset radix. In order to ensure that the ultrasonic transmission signal does not interfere with the human ear and to reduce the interference between each encoding frequency as much as possible, a frequency interval of 100 Hz is adopted, and the frequency interval can be selected as 80-200 Hz through experiments, and the specific range can be adjusted. As an example, the marker frequencies corresponding to different regions can be set in the band of 20000-20290 Hz, and so on. Starting from 20300 Hz, each increment of 100 Hz corresponds to a total of 16 frequencies (20300-21800 Hz), which are responsible for transmitting 16-radix encoding characters 0-F, that is, 20300 Hz is used as the encoding frequency of the character 0 in the hexadecimal system (i.e., the frequency 20300 Hz corresponds to the hexadecimal character 0), 20400 Hz is used as the encoding frequency of the character 1 in the hexadecimal system, and so on, and 21800 Hz is used as the encoding frequency of the character F in the hexadecimal system.

[0088] In step S330, the target marker frequency is taken as a first sequence header, the first encoded sequence and the second encoded sequence are combined into a first sequence body, and the first sequence header and the first sequence body are spliced to obtain a first encoding frequency sequence.

[0089] When the first encoded sequence and the second encoded sequence are combined, a marker for distinguishing the first encoded sequence and the second encoded sequence is arranged in the first sequence body, for example, the marker can be a set marker or a set interval between the first encoded sequence and the second encoded sequence, or a flag bit is arranged in the sequence header of each of the first encoded sequence and the second encoded sequence, and in the subsequent decoding process, the two parts of information contained in the first sequence body can be distinguished based on the marker.

[0090] In step S340, the amplitude of the first encoding frequency sequence is modulated to the target ultrasonic amplitude, or the power of the first encoding frequency sequence is modulated to the target ultrasonic power; and the first encoding frequency sequence obtained after modulation is taken as a taking ultrasonic carrier signal.

[0091] In the embodiment comprising steps S310-S340, the locker identifier and the pick-up code information corresponding to the to-be-picked item are encoded and amplitude (or power) modulated based on the target ultrasonic carrier information corresponding to the to-be-picked item, and a sequence header is generated and amplitude modulated according to the target marker frequency indicating different areas to obtain the pick-up ultrasonic carrier signal. In the case where the distance between different lockers in the same area is far, the target ultrasonic carrier information for different lockers in the same area can be the same, and the interference between different pick-up ultrasonic carrier signals is relatively small. In some cases, in order to solve the following technical problems found: the case of receiving multiple pick-up ultrasonic carrier signals at the same time, the interference between different pick-up ultrasonic carrier signals is easy to produce, which affects the analysis and decoding process, the following scheme is adopted: the target ultrasonic carrier information for different lockers in the same area is different. In the case where the target ultrasonic carrier information for different lockers in the same area is different, the above target ultrasonic carrier information is used to distinguish different lockers in the same area in at least one dimension of amplitude or frequency.

[0092] In step S240, the pick-up ultrasonic carrier signal is sent to the locker based on the audio module of the terminal device. The pick-up ultrasonic carrier signal is used to control the target locker corresponding to the locker identifier to perform the pick-up door opening operation.

[0093] For example, in the space where the terminal device is located, one or more lockers receive the pick-up ultrasonic carrier signal, analyze and decode the pick-up ultrasonic carrier signal to obtain the target marker frequency, the locker identifier corresponding to the to-be-picked item, and the pick-up code information. The target marker frequency matches the positioning information of the terminal device. The target marker frequency, the locker identifier, and the pick-up code information are checked. In the case where the target marker frequency, the locker identifier, and the pick-up code information are all checked (for the target locker), the target compartment is executed according to the pick-up code information. The pick-up door opening operation is performed.

[0094] In the embodiment comprising steps S210-S240, the pick-up ultrasonic carrier signal is transmitted between the terminal device and the storage cabinet (which can be a delivery cabinet, an article storage cabinet set by a supermarket, etc.) based on the ultrasonic form. The ultrasonic wave can efficiently transmit signals in a short distance, effectively utilize the audio module (self-contained hardware device) of the terminal device and the storage cabinet to reduce or even avoid the risk of contact infection caused by human operation of the operation screen on the storage cabinet. Meanwhile, the pick-up ultrasonic carrier signal is generated according to the target marker frequency matched with the positioning information of the terminal device, the storage cabinet identifier corresponding to the pick-up, and the pick-up code information. The information carried by the pick-up ultrasonic carrier signal includes three kinds of information. The target marker frequency is used to distinguish different areas (for example, the areas can be different city areas, such as Beijing area and Tianjin area with different marker frequencies; or different fragments of a city, such as Haidian District of Beijing and Chaoyang District of Beijing) where the terminal device is located. The marker frequency corresponding to different areas is different. Based on the target marker frequency, the area to which the storage cabinet belongs can be distinguished. Based on the storage cabinet identifier, different storage cabinets can be distinguished. Especially, the storage cabinets close to each other can identify whether the pick-up control signal received is for themselves based on the storage cabinet identifier. Based on the pick-up code information, the opening control of the target compartment can be realized. The pick-up can be realized without contact. In the scenarios of multiple pick-ups for the same storage cabinet, multiple synchronous pick-ups for different storage cabinets in the same area, and multiple synchronous pick-ups for different storage cabinets in different areas, on the one hand, the mutual interference caused by close-range synchronous pick-up can be reduced, and on the other hand, the server can distinguish the pick-up processes of different areas and different storage cabinets.

[0095] Figure 4 A flowchart of a pick-up method applied to a terminal device according to another embodiment of the present disclosure is schematically shown.

[0096] According to the embodiments of the present disclosure, in addition to the above steps S210-S240, the method applied to the terminal device further comprises the following steps: S410, S420, S430, S440 and S450. For simplicity, only steps S410-S450 are shown in Figure 4 For the same pick-up process, steps S410-S450 are executed after step S240.

[0097] For example, in an implementation scenario, after the terminal device executes steps S210-S240, the target storage cabinet controls the target compartment to open. This opening action serves as a trigger condition for the above-mentioned storage cabinet to generate and send the pick-up confirmation ultrasonic carrier signal. The subsequent description is simplified as a door opening trigger scenario.

[0098] In another implementation scenario, after the terminal device executes steps S210~S240, the target locker controls the target compartment to open, the user takes out the items inside and closes the door. The closing action can serve as a triggering condition for the locker to generate and send a retrieval confirmation ultrasonic carrier signal, which will be simplified as a closing trigger scenario below.

[0099] In step S410, the device receives an ultrasonic carrier signal confirming item retrieval from the locker, based on the audio module of the terminal device.

[0100] After the terminal device sends a pickup ultrasonic carrier signal to the locker, the target locker will send a pickup confirmation ultrasonic carrier signal to the terminal device in the same pickup process. Since there may be multiple lockers in the same space where the locker is located and pickups are being made at the same time, the sent pickup confirmation ultrasonic carrier signal is non-directional and is broadcast. The signal corresponding to the terminal device in the current pickup process can be identified by parsing the pickup confirmation ultrasonic carrier signal.

[0101] In step S420, the ultrasonic carrier signal for item retrieval confirmation is analyzed and decoded to obtain item retrieval confirmation information.

[0102] In some embodiments, the above-mentioned pickup confirmation information includes: the target locker identifier and pickup information for performing the pickup opening operation; the above-mentioned pickup information includes, but is not limited to: pickup compartment information (e.g., compartment number or compartment coordinates), pickup item information (e.g., the package tracking number, logistics tracking number, or contents of the pickup item), and pickup person information (e.g., including but not limited to: the actual pickup person's name, mobile phone number, etc.; whether it is a pickup on behalf of someone else or by the pickup person themselves, etc.).

[0103] Figure 5 A detailed implementation flowchart of step S420 according to an embodiment of the present disclosure is shown schematically.

[0104] According to embodiments of this disclosure, referring to Figure 5 As shown, in step S420 above, the ultrasonic carrier signal for item retrieval confirmation is parsed and decoded to obtain item retrieval confirmation information, including the following steps: S510, S520, S530a or S530b.

[0105] In step S510, the signal head of the ultrasonic carrier signal for confirming the item retrieval is parsed to obtain the item retrieval device identifier.

[0106] The identification of the pickup device may include, but is not limited to: device serial number, login account (such as username or user mobile phone number) on the terminal device corresponding to the same pickup process, etc.

[0107] At step S520, the pickup device identifier is verified according to the device identifier of the terminal device.

[0108] At step S530a, if the pickup device identifier is verified, the signal body of the pickup confirmation ultrasonic carrier signal is decoded to obtain pickup confirmation information.

[0109] At step S530b, if the pickup device identifier is not verified, an error information of non-device processing is returned, or the decoding of the pickup confirmation ultrasonic carrier signal and the presentation of the pickup confirmation interface are not performed.

[0110] Considering that there can be multiple lockers in the same space, in the scenario of multiple people simultaneously picking up from multiple lockers, the pickup confirmation ultrasonic carrier signals sent by multiple lockers will be fed back to the terminal devices corresponding to the multiple people. Therefore, how to avoid interference between these simultaneously received pickup confirmation ultrasonic carrier signals and achieve directional discrimination of information is a key problem.

[0111] Therefore, in the embodiments including steps S510, S520, S530a or S530b, the pickup device identifier is constructed as the signal header of the pickup confirmation ultrasonic carrier signal. Therefore, after receiving multiple pickup confirmation ultrasonic carrier signals at the terminal device side, it can be identified according to the differences in the signal header which pickup confirmation ultrasonic carrier signals are for itself and continue to perform subsequent processing operations, and which do not need to be processed by itself. The terminal device does not need to analyze and decode multiple received pickup confirmation ultrasonic carrier signals, reduces the workload and resource consumption of the part that is not processed by itself, and improves the pickup confirmation processing efficiency of the terminal device.

[0112] Specifically, the following technical solutions can be used on the locker side (which can be combined with the third embodiment for reference and understanding): generating a pickup confirmation ultrasonic carrier signal according to a target locker identifier corresponding to a target compartment and pickup information, including: determining a pickup device identifier as a second sequence header; analyzing the target locker identifier and the pickup information to obtain a third string and a fourth string corresponding to a preset base; generating a third encoding sequence and a fourth encoding sequence for encoding the third string and the fourth string according to an encoding frequency in a target ultrasonic carrier frequency band corresponding to the locker for encoding characters of the preset base; the encoding frequencies corresponding to different characters of the preset base have a preset frequency interval; combining the second sequence header, the third encoding sequence and the fourth encoding sequence to obtain a second encoding frequency sequence; modulating the amplitude of the second encoding frequency sequence to a target ultrasonic amplitude, or modulating the power of the second encoding frequency sequence to a target ultrasonic power; the second encoding frequency sequence obtained after modulation is used as the pickup confirmation ultrasonic carrier signal.

[0113] In step S430, according to the above pick-up confirmation information, a pick-up confirmation interface is presented.

[0114] The above pick-up confirmation interface is presented on a terminal device corresponding to the pick-up device identifier, for example, the pick-up confirmation information is displayed on the pick-up confirmation interface.

[0115] In step S440, based on the above pick-up confirmation interface, a pick-up confirmation instruction of the user is received.

[0116] In the door opening trigger scenario or the door closing trigger scenario, the user can check and verify the pick-up confirmation information on the above pick-up confirmation interface, and if the verification is correct, the user can click the pick-up confirmation button on the pick-up confirmation interface, and the terminal device is regarded as receiving the pick-up confirmation instruction.

[0117] If in the door opening trigger scenario, the user takes out the goods, and the above information is incorrect, for example, the pick-up goods information is incorrect, which may indicate that the goods stored in the target compartment corresponding to the issued pick-up code information are not the user's goods. The user can select (the options can be improved according to the actual situation) or input the corresponding feedback information on the pick-up confirmation interface, and then click the pick-up confirmation button. The corresponding feedback information will also be sent to the server synchronously, and the server will be stored in the pick-up record. In this case, the user finds that the goods are not needed, and will put the goods back to the corresponding compartment and close the door.

[0118] If in the door closing trigger scenario, the user takes out the goods, and the above information is incorrect, for example, the pick-up goods information is incorrect, which may indicate that the goods stored in the target compartment corresponding to the issued pick-up code information are not the user's goods. The user can select (the options can be improved according to the actual situation) or input the corresponding feedback information on the pick-up confirmation interface, and then click the pick-up confirmation button. The corresponding feedback information will also be sent to the server synchronously, and the server will be stored in the pick-up record; at the same time, the corresponding compartment will be opened again so that the user can put back the corresponding goods. Since in the door closing trigger scenario, the door of the target compartment is already in the closed state when the user finds that the goods are not correct; therefore, by setting the following logic: after the user clicks the pick-up confirmation button and the corresponding feedback information is synchronized to the server, the server will control the corresponding compartment to be opened according to the feedback information; so that the user can put back the corresponding goods.

[0119] In step S450, the above pick-up confirmation information and pick-up confirmation instruction are uploaded to the server.

[0120] The above pick-up confirmation information and pick-up confirmation instruction are used for storing in the pick-up record and for pick-up verification and tracing.

[0121] In some implementation scenarios, the above pick-up confirmation instruction includes feedback information and record person information when there is a problem.

[0122] In the embodiment comprising the above steps S410-S450, the pick-up confirmation ultrasonic carrier signal is transmitted between the locker (which can be a delivery cabinet, an article storage cabinet set by a supermarket, etc.) and the terminal device based on the ultrasonic form. The ultrasonic wave can efficiently transmit signals in a short distance, effectively utilize the audio module (self-contained hardware device) of the terminal device and the locker, and reduce or even avoid the risk of contact infection caused by human operation of the operation screen on the locker. The information carried by the above pick-up confirmation ultrasonic carrier signal includes two kinds of information: pick-up device identification and pick-up confirmation information. By constructing the pick-up device identification as the signal header of the pick-up confirmation ultrasonic carrier signal, when the terminal device side receives multiple pick-up confirmation ultrasonic carrier signals, it can identify which pick-up confirmation ultrasonic carrier signal is for itself and continue the subsequent processing operation, and which does not need to be processed by itself. The terminal device does not need to analyze and decode all the received pick-up confirmation ultrasonic carrier signals, reduces the workload and resource consumption of the part that is not processed by itself, and improves the pick-up confirmation processing efficiency of the terminal device. Based on the pick-up confirmation information, the terminal device side can check the information and effectively identify the case where the article stored in the compartment does not match the pick-up information issued. For example, taking a delivery cabinet as an example, the courier may place article S in compartment X, but the result is that article T is placed in compartment X. The pick-up code issued by the server is for article T. When the user of article T picks up the article, it is found that the article placed in compartment X is not his own article. By inputting or selecting the corresponding feedback information on the pick-up confirmation interface, some data association errors or other system errors can be effectively identified, and the data supervision and tracing of the article storage process can be facilitated through the pick-up record of the server.

[0123] A third exemplary embodiment of the present disclosure provides a pick-up method applied to a locker.

[0124] Figure 6 A flowchart of a pick-up method applied to a locker according to an embodiment of the present disclosure is schematically shown.

[0125] Referring to Figure 6 The pick-up method applied to a locker provided by the embodiment of the present disclosure includes the following steps: S610, S620, S630 and S640.

[0126] In step S610, based on the audio module of the above locker, a pick-up ultrasonic carrier signal sent by a terminal device is received.

[0127] In step S620, the pick-up ultrasonic carrier signal is analyzed and decoded to obtain a target marker frequency, a locker identification corresponding to a to-be-picked-up article, and a pick-up code information.

[0128] The target flag frequency is matched with the positioning information of the terminal device.

[0129] According to an embodiment of the present disclosure, in the step S620, the pick-up ultrasonic carrier signal is parsed and decoded to obtain the target flag frequency, the locker identification corresponding to the to-be-picked item, and the pick-up code information, including:

[0130] The signal header of the pick-up ultrasonic carrier signal is parsed to obtain the target flag frequency; the target ultrasonic carrier frequency band corresponding to the locker is obtained from the server; since the target ultrasonic carrier information corresponding to the locker is issued by the server, or the target ultrasonic carrier information selected by the user in the ultrasonic carrier option is synchronized to the server, the target ultrasonic carrier frequency band corresponding to the locker can be obtained from the server.

[0131] According to the target ultrasonic carrier frequency band, the signal body of the pick-up ultrasonic carrier signal is decoded to obtain the locker identification corresponding to the to-be-picked item and the pick-up code information.

[0132] In the process of decoding the signal body, the two-part information (the locker identification corresponding to the to-be-picked item and the pick-up code information) contained in the first sequence body can be distinguished based on the mark, which can be understood in combination with the related description of the second embodiment.

[0133] In step S630, the target flag frequency, the locker identification, and the pick-up code information are verified.

[0134] According to an embodiment of the present disclosure, in the step S630, the target flag frequency, the locker identification, and the pick-up code information are verified, including: determining the corresponding area flag frequency according to the area where the locker is located; verifying whether the target flag frequency is consistent with the area flag frequency; in the case that the target flag frequency is consistent with the area flag frequency, verifying the locker identification corresponding to the to-be-picked item; for example, verifying whether the identification is consistent with the current locker; in the case that the locker identification verification is passed, verifying the pick-up code information. In the process of verifying the pick-up code information, for example, the pick-up code information can be verified to be consistent with the issued pick-up code for opening the compartment of the current locker, and the issued pick-up code is issued to the locker and the terminal device by the server.

[0135] In some embodiments, step S630 can further include a step corresponding to a negative branch: if the target flag frequency is inconsistent with the region flag frequency, the locker identification and the pick-up code information are no longer checked, and a first error message is presented; if the locker identification check fails, the pick-up code information is no longer checked, and a second error message is presented; if the pick-up code information check fails, a third error message is presented. The specific content of the first error message to the third error message can be set according to actual conditions.

[0136] In step S640, if the target flag frequency, the locker identification, and the pick-up code information are all checked, the target compartment is opened according to the pick-up code information. That is, if the execution result of step S630 is yes, step S640 is executed.

[0137] The pick-up code information is used to open the target compartment of the target locker, and the target locker controls the target compartment to open if the target flag frequency, the locker identification, and the pick-up code information are all checked.

[0138] The embodiments of steps S610-S640 can be combined with the terminal device side interaction in the second embodiment.

[0139] In the embodiment comprising steps S610-S640, the pick-up ultrasonic carrier signal is transmitted between the terminal device and the storage cabinet (which can be a delivery cabinet, an article storage cabinet set by a supermarket, etc.) based on the ultrasonic form. The ultrasonic wave can efficiently transmit signals in a short distance, effectively utilize the audio module (self-contained hardware device) of the terminal device and the storage cabinet to reduce or even avoid the risk of contact infection caused by human operation of the operation screen on the storage cabinet. Meanwhile, the pick-up ultrasonic carrier signal is generated according to the target marker frequency matched with the positioning information of the terminal device, the storage cabinet identifier corresponding to the pick-up article, and the pick-up code information. The information carried by the pick-up ultrasonic carrier signal includes three kinds of information. The target marker frequency is used to distinguish different areas (for example, the areas can be different city areas, such as Beijing area and Tianjin area with different marker frequencies; or different fragments of a city, such as Haidian District of Beijing and Chaoyang District of Beijing) where the terminal device is located. The marker frequency corresponding to different areas is different. Based on the target marker frequency, the area to which the storage cabinet belongs can be distinguished. Based on the storage cabinet identifier, different storage cabinets can be distinguished. Especially, the storage cabinets close to each other can identify whether the pick-up control signal received is for themselves based on the storage cabinet identifier. Based on the pick-up code information, the opening control of the target compartment can be realized. In the scenarios of contactless pick-up, multi-person pick-up for the same storage cabinet, multi-person synchronous pick-up for different storage cabinets in the same area, and multi-person synchronous pick-up for different storage cabinets in different areas, on the one hand, the mutual interference caused by close-range synchronous pick-up can be reduced, and on the other hand, the server can distinguish the pick-up process of different areas and different storage cabinets.

[0140] Figure 7 The interaction timing diagram in the process of the terminal device, the storage cabinet, and the server performing the pick-up method according to an embodiment of the present disclosure is schematically shown.

[0141] According to an embodiment of the present disclosure, referring to Figure 7 The method applied to the storage cabinet further comprises the following steps: S710 and S720 in addition to the above steps S610-S640. In some embodiments, step S730 can also be included.

[0142] In step S710, in the case that the target compartment is successfully opened, a pick-up confirmation ultrasonic carrier signal is generated according to the target storage cabinet identifier corresponding to the target compartment and the pick-up information.

[0143] In the case that the target compartment is successfully opened, the pick-up confirmation ultrasonic carrier signal can be generated by triggering the opening of the compartment, or the pick-up confirmation ultrasonic carrier signal can be generated by triggering the closing of the compartment. The specific description can be combined with the related description of steps S410-S450 in the second embodiment, which will not be repeated here.

[0144] According to the embodiment of the present disclosure, in step S710, the pick-up confirmation ultrasonic carrier signal is generated according to the target locker identifier corresponding to the target slot and the pick-up information.

[0145] The pick-up device identifier is determined as the second sequence header; the pick-up device identifier can be, but is not limited to, a device serial number, a login account (such as a user name or a user mobile phone number, etc.) on a terminal device corresponding to the same pick-up process, etc.

[0146] The target locker identifier and the pick-up information are parsed respectively, and the third string and the fourth string corresponding to the preset radix are obtained;

[0147] According to the encoding frequency of the target ultrasonic carrier frequency band corresponding to the locker for encoding the characters of the preset radix, the third encoding sequence and the fourth encoding sequence for encoding the third string and the fourth string are generated; the encoding frequencies corresponding to different characters of the preset radix have a preset frequency interval;

[0148] The second sequence header, the third encoding sequence and the fourth encoding sequence are combined to obtain the second encoding frequency sequence; when the third encoding sequence and the fourth encoding sequence are combined, a distinguishing mark for distinguishing the third encoding sequence and the fourth encoding sequence can be set, for example, the distinguishing mark can be a set mark symbol or a set interval between the third encoding sequence and the fourth encoding sequence, or a flag bit in the sequence header of the third encoding sequence and the fourth encoding sequence, etc., and the target locker identifier and the pick-up information can be distinguished based on the distinguishing mark in the subsequent decoding process;

[0149] The amplitude of the second encoding frequency sequence is modulated as the target ultrasonic wave amplitude, or the power of the second encoding frequency sequence is modulated as the target ultrasonic wave power; the second encoding frequency sequence after modulation is used as the pick-up confirmation ultrasonic carrier signal.

[0150] In step S720, the pick-up confirmation ultrasonic carrier signal is broadcasted in the space where the locker is located. One or more terminal devices located in the space where the locker is located can receive the pick-up confirmation ultrasonic carrier signal.
