[0048] First, the vocabulary involved in the embodiments of the present application is explained. It can be understood that this explanation is for a clearer understanding of the embodiments of the present application, and does not necessarily constitute a limitation on the embodiments of the present application.

[0049] Cargo box: a storage unit or storage form of goods, in which the goods themselves are placed. Exemplarily, the goods mentioned in some embodiments of the present application exist in the form of cargo boxes.

[0050] Pallet: A device used to carry boxes (or goods), usually made of wood, plastic, metal and other materials.

[0051] Forklift: Forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods (goods carried on pallets are called palletized goods). Forklifts include a fork frame and a fork mounted on the fork frame. The fork is the most basic and common picking device of the forklift, usually composed of a horizontal section and a vertical section, wherein the horizontal section is used to pick up goods, and the vertical section is connected to the fork frame.

[0052] High-rise shelves (or high-rise shelves) refer to steel structures used to store palletized goods. High-rise shelves are usually more than ten meters high, or even higher, providing a large amount of storage space for palletized goods. The cargo space on the high-priced shelves can be called high-rise cargo space.

[0053] The ground pile area (also called ground pile shelf) refers to the area where goods are stacked directly on the ground. The cargo space in the ground pile area can be called ground pile cargo space.

[0054] Radio Frequency Identification (RFID) technology is a technology that uses radio signals for contactless automatic identification and data transmission. It mainly includes two parts: RFID tags (hereinafter referred to as tags) and RFID readers (hereinafter referred to as readers). Tags are information carriers, usually composed of built-in antennas and chips. The chip stores identification information for uniquely identifying objects. Tags can obtain energy by sensing radio frequency signals emitted by readers, and activate the chip in the tag to send the information stored in the chip to the reader through the built-in antenna; the reader is responsible for reading (and writing) the information in the tag. The reader transmits a radio frequency signal of a certain frequency through the antenna. When the tag enters its working area, the tag is activated and the information stored in it is read, and the decoding process is performed to complete the identification of the tag. In some embodiments, the above reader can be called a reader-writer.

[0055] A dock refers to a facility designed for loading and unloading goods. It is a platform for loading and unloading goods. Its main purpose is to ensure that forklifts can safely and efficiently enter and exit transport vehicles for loading and unloading of goods. The design of the dock takes into account the height difference between vehicles. Usually, a dock adjustment plate is installed as a transition bridge between the vehicle and the dock to adjust the height difference between the two to prevent forklifts from being unable to directly enter and exit the carriage for loading and unloading.

[0056] Inbound warehousing: The process of transporting palletized goods from outside to the warehouse.

[0057] Shifting: The process of moving palletized cargo from one location to another.

[0058] Outbound delivery: The process of taking palletized goods out of the warehouse and shipping them outside.

[0059] Warehouse Management System (WMS) is a real-time computer software system designed to help companies manage daily warehouse operations, covering all aspects from the time goods enter the warehouse to the time they leave the warehouse.

[0060] Inventory turnover refers to the entire process that goods / pallets used to carry goods (also known as cargo pallets) go through from entering the warehouse to leaving the warehouse, including: entering the warehouse, shifting, leaving the warehouse and other links.

[0061] Shelving: refers to taking out or removing the loading pallet from the storage location.

[0062] Unloading: refers to placing the cargo pallet on the cargo space.

[0063] Internet of Things: It is a network based on information carriers such as the Internet and traditional telecommunication networks, which enables all ordinary physical objects that can be independently addressed to be interconnected. That is, all objects are connected to the Internet through information sensing devices to exchange information, so that things can communicate with each other to achieve intelligent identification, positioning, tracking and management.

[0064] Figure 1 This is an internal layout diagram of a warehouse involved in an embodiment of the present application. Figure 1 As shown, the warehouse includes: a sorting area 10 and a storage area 11.

[0065] Among them, the main functions of the tally area include cargo reception and inspection, classification and sorting, information entry, and pallet binding. Among them, information entry refers to entering cargo information of the cargo, wherein the cargo information may include but is not limited to the cargo identification, product name, specification, quantity, weight, and volume that uniquely identify the cargo. In actual operation, the tally personnel can obtain the above cargo information by scanning the mark on the cargo (usually, the mark includes a barcode) through a handheld personal digital assistant (PDA). The tally personnel assign a pallet to each cargo, place each cargo on the assigned pallet, and use the PDA device to scan the pallet label on the pallet and the cargo label of the cargo on the pallet, thereby realizing the binding of the cargo to the pallet. For example: the PDA device sends the pallet label information obtained by scanning the pallet label and the cargo information obtained by scanning the mark to the warehouse management device, so that the warehouse management device establishes and records the binding relationship between the pallet and the cargo. Among them, the pallet label information for identifying the pallet is stored in the pallet label on the pallet. Exemplarily, the pallet label can be an RFID tag. Among them, the PDA device has one-dimensional barcode and label recognition capabilities, wireless networking capabilities and a visual operation screen, and can be used for daily receipt and sorting of cargo boxes, manual confirmation of inventory transfer operations within the warehouse, and inventory counting.

[0066] In an optional embodiment, the pallet label can be set on the side of the pallet, such as Figure 2 As shown, the pallet label 21 is arranged on the side of the pallet 2. For example, the pallet label can be arranged on all four sides of the pallet. Figure 2 As shown, the pallet includes a first side surface 22 and a second side surface 23 that are arranged opposite to each other, wherein the first side surface 22 and the second side surface 23 are both provided with an insertion opening 200 for inserting a forklift fork, and the first side surface 22 and the second side surface 23 are provided with a pallet label 21. Figure 2 As shown, the pallet 2 may further include a third side surface 24 and a fourth side surface 25 that are arranged opposite to each other, wherein a pallet label 21 is arranged on the third side surface 24 and the fourth side surface 25 .

[0067] It should be noted that the pallet labels 21 on the first side 22 and the second side 23 are read by the label reader on the forklift; the pallet labels 21 on the third side 24 and the fourth side 25 are read by the label reader on the sensing device (for example: sensing door) set at the warehouse passage entrance.

[0068] Exemplarily, the pallet label 21 may be a cover label.

[0069] In actual warehouse operation scenarios, goods are carried on pallets to facilitate forklifts to pick up goods, thereby improving the operating efficiency of forklifts. In some embodiments, the pallet and the goods carried on the pallet can be regarded as an inventory object as a whole, that is, the pallet carrying goods is regarded as an inventory object.

[0070] In other embodiments, when the structure of the goods is suitable for forklift, the goods do not need to be bound to the pallet, and the goods themselves can be regarded as an inventory object. In this case, a goods label can be set on the goods (for example, the side of the goods), and the goods label information for uniquely identifying the goods is stored in the goods label.

[0071] The above-mentioned inventory area is used to store inventory objects. The above-mentioned inventory area includes: one or more high-level shelves and one or more ground storage areas. Figure 3 As shown, the high-level shelf 3 includes a plurality of cargo spaces 31, and a cargo space label 32 for uniquely identifying the cargo space is provided on each cargo space 31. The cargo space label provided on the cargo space stores cargo space label information for identifying the cargo space.

[0072] Exemplarily, the cargo location label 32 may be disposed at the entrance and exit of the cargo location to facilitate the label reader on the forklift to read when loading and unloading the pallet.

[0073] like Figure 4 As shown, the ground stack area 4 includes a plurality of cargo locations 41 , and each cargo location 41 is provided with a cargo location label 42 .

[0074] For example, Figure 4 As shown, the cargo location labels 42 arranged on the cargo locations in the ground pile area 4 may be buried labels arranged on the ground.

[0075] For example, Figure 3 As shown, the cargo location labels 31 set on the cargo locations on the high shelf 3 that are in contact with the ground can be buried labels set on the ground, and the cargo location labels 31 set on other cargo locations on the high shelf 3 can be surface labels set on the side of the shelf and located near the entrance and exit of the cargo location.

[0076] Note: Figure 3 and Figure 4The direction of the arrow in the figure is the direction in which the fork releases the pallet, which is also the direction in which the pallet enters the cargo space.

[0077] In this embodiment, the entire warehouse can construct a digital point map of four dimensions of warehouse-inventory area-shelf-cargo location through RFID tags and cargo location coding rules.

[0078] In some embodiments, Figure 1 As shown, the storage area 11 is physically isolated from other areas by a physical fence, wherein the physical fence is provided with passages connected to other areas, such as an entry and exit. Figure 1 As shown, an electric gate 12 is provided at the entrance to the warehouse for blocking the entrance, and a sensing device 13 is provided on the outside of the electric gate 12. The side of the electric gate 12 outside the inventory area is called the outside, and the side of the electric gate 12 inside the inventory area is called the inside. The sensing device 13 is provided with a sensor and a second tag reader.

[0079] Exemplarily, the electric gate may be an electric sliding door.

[0080] Exemplarily, the sensing device is a sensing door.

[0081] Exemplarily, the second tag reader may be an RFID tag reader, and the above-mentioned sensing door may be referred to as an RFID sensing door.

[0082] Exemplarily, the sensor may be a distance sensor or a pressure sensor, and its working principle will be introduced in the following embodiments.

[0083] like Figure 5 As shown, this is a diagram showing the positional relationship between the induction door 51 and the electric sliding door 52.

[0084] When the sensor detects that a forklift carrying an inventory object arrives at the sensing area corresponding to the sensing device, the sensor triggers the second tag reader on the sensing device to read the tag, and the sensing device reports the tag reading result to the warehouse management device. The warehouse management device can verify with the warehouse management data to determine whether the forklift is allowed to pass. The verification result will be synchronously fed back to the controller of the electric gate. If the forklift is allowed to pass, the controller controls the electric gate to open and automatically close after the preset time. The preset time can be dynamically configured according to the operating efficiency of the warehouse personnel, and can be 10 seconds by default.

[0085] like Figure 1As shown, a packing platform 14 is provided at the outbound port, and a sensing device 15 is provided on the inner side of the packing platform. The side of the packing platform 14 located in the inventory area is called the inner side, and the side of the packing platform 14 located outside the inventory area is called the outer side. Sensors and label readers are provided on the sensing device 15. Exemplarily, the sensing device includes a sensing door. When the sensor detects that a forklift carrying an inventory object arrives at the sensing area corresponding to the sensing device, the sensor triggers the second label reader on the sensing device to read the label, and the sensing device reports the label reading result to the warehouse management device. The warehouse management device can verify in combination with the warehouse record data to determine whether the forklift is allowed to pass. In the shipping scenario, the forklift passes through the sensing area corresponding to the sensing device and carries the inventory object to the truck located outside the packing platform.

[0086] In some optional embodiments, an electric gate (not shown) may be provided at the warehouse exit between the sensing device 15 and the packing platform 14 to physically isolate the warehouse exit.

[0087] In addition, each of the above-mentioned sensing devices may also be provided with a warning unit, such as a warning light and a buzzer. The warehouse management device may also synchronously feed back the verification result to the sensing device. If passage is allowed, the sensing device controls the indicator light to turn green. Otherwise, the indicator light turns red and the buzzer sounds an alarm.

[0088] An embodiment of the present application provides a forklift, on which a first tag reader and a motion detection unit are provided, wherein the first tag reader is used to read cargo location tag information in a cargo location tag and object tag information in an object tag. Exemplarily, when the inventory object is a pallet carrying goods, the object tag refers to the pallet tag on the pallet, and the object tag information refers to the pallet tag information stored in the pallet tag. Exemplarily, when the inventory object is the goods themselves, the object tag refers to the goods tag on the goods, and the object tag information refers to the goods tag information stored in the goods tag.

[0089] The setting position of the action detection unit can be set according to actual needs, and the embodiment of the present application does not make any specific restrictions on this. It only needs to be able to detect the preset action of the forklift. The preset action may include the action of the forklift picking up the inventory object and the action of the forklift putting down the inventory object. The setting position of the first tag reader can be set according to actual needs. The embodiment of the present application does not make any specific restrictions on this. It only needs to be able to identify the object tag on the inventory object when the forklift picks up or puts down the inventory object, and to be able to identify the cargo location tag on the cargo location when the forklift picks up or puts down the inventory object.

[0090] Exemplarily, the above-mentioned motion detection unit includes but is not limited to a pressure sensor and a distance sensor, wherein the distance sensor may be an infrared sensor or a laser sensor.

[0091] In an optional embodiment, the pressure sensor is used to detect pressure. When the pressure is detected to be greater than or equal to a first preset pressure threshold, it can be determined that the forklift has detected the action of picking up the inventory object; when the pressure is detected to be less than or equal to a second preset pressure threshold, it can be determined that the forklift has detected the action of putting down the inventory object. The first preset pressure threshold is greater than the second preset pressure threshold. The second preset pressure threshold can be 0.

[0092] In another optional embodiment, the pressure sensor includes a spring piece; when the forklift picks up the inventory object, the spring piece is deformed under the pressure of the inventory object; when the forklift puts down the inventory object, the spring piece returns to its original state; when the motion detection unit detects that the spring piece is deformed, the motion detection unit determines that the motion of the forklift picking up the inventory object is detected; when the motion detection unit detects that the spring piece returns to its original state, the motion detection unit determines that the motion of the forklift putting down the inventory object is detected.

[0093] The distance sensor is used to detect the distance to the object. When the distance is detected to be smaller and less than or equal to a first preset distance threshold, it can be determined that the forklift has picked up the inventory object; when the distance is detected to be larger and greater than or equal to a second preset distance threshold, it can be determined that the forklift has put down the inventory object. The first preset distance threshold is less than the second preset pressure threshold.

[0094] Figure 6 This is a schematic diagram of the structure of a forklift provided in one embodiment of the present application. Figure 6 As shown, the forklift 6 includes a fork 61. Figure 7 As shown, the forklift 6 includes two L-shaped forks 61, and the L-shaped forks 61 include a vertical section and a horizontal section, wherein the horizontal section is used to carry the pallet, and the vertical sections of the two L-shaped forks 61 are connected by a connecting rod 71, and the motion detection unit 72 is arranged on the connecting rod 71.

[0095] like Figure 7 As shown, the motion detection unit 72 is disposed on the side of the connecting rod 71 facing the inventory object accommodating space 700 .

[0096] As an option, the motion detection unit 72 may also be disposed on the side of the horizontal section of the L-shaped fork 61 facing the inventory object accommodating space 700 (ie, the bearing surface for bearing the inventory objects).

[0097] Optionally, the first tag reader 73 includes a host and an antenna.

[0098] Exemplarily, the antenna in the first tag reader 73 may be disposed on the connecting rod 71 .

[0099] The antenna may include but is not limited to: a linear antenna and a planar antenna.

[0100] In an optional embodiment, the antenna is a planar antenna. In order to adapt to reading buried tags set on the ground and surface tags set on the side (for example, the side of the shelf, the side of the pallet, the side of the goods), the tag reader 73 may include two planar antennas, and the reflection surfaces of the two planar antennas are oriented in different directions to read tags in different directions. For example, Figure 7 As shown, the reflecting surface of one of the planar antennas 73 is oriented directly downward (i.e., at 90 degrees to the horizontal plane) and is used to read buried tags, and the reflecting surface of the other planar antenna 74 is oriented obliquely downward (i.e., its orientation is set at an acute angle to the horizontal plane, for example, 45 degrees) and is used to read the face label on the side of the pallet (or the face label on the side of the goods) and the face label on the side of the shelf.

[0101] It should be noted that the number, position and orientation of the antennas in the first tag reader 73 can be set according to actual needs, and the embodiment of the present application does not specifically limit this.

[0113] 901. When the action detection unit detects a preset action of the forklift on the inventory object, the action detection unit triggers the first tag reader to read the tag and obtain a first tag reading result.

[0114] The first tag reading result includes object tag information read from an object tag, the object tag is set on the inventory object, and the object tag information is used to identify the inventory object.

[0115] In some embodiments, the inventory object refers to the pallet carrying goods in the above embodiments, the object tag refers to the pallet tag set on the pallet, and the pallet tag information read from the pallet tag is the object tag information.

[0116] In actual applications, some preset actions may be specified in advance, such as an action of a forklift picking up an inventory object and an action of a forklift putting down an inventory object.

[0117] It should be noted that the preset action can be specified according to the actual application scenario, and the embodiments of the present application do not make specific limitations on this.

[0118] The specific implementation of the action detection unit detecting the preset action can refer to the corresponding content in the above embodiments, which will not be repeated here.

[0119] In an optional embodiment, the first tag reading result refers to the target tag reading result of the first tag reader at the first target moment. In some embodiments, the tag reading result of the first tag reader at the first target moment can be directly used as the target tag reading result. In other embodiments, the target tag reading result of the first tag reader at the first target moment can be determined based on the tag reading result of the first tag reader within a preset time range before and / or after the first target moment. Exemplarily, the tag reading result with the highest frequency of occurrence within this preset time range can be used as the target tag reading result. It should be noted that the duration of the above-mentioned preset time range can be set according to actual needs, and the embodiment of the present application does not specifically limit this, for example: 1s. It should be additionally noted that the tag reader uses the tag information with a signal strength greater than or equal to the preset strength threshold read at each moment as the tag reading result at that moment. When the tag reader does not read the tag information with a signal strength greater than or equal to the preset strength threshold at a certain moment, it is determined that there is no tag reading result at that moment.

[0120] In some embodiments, when the motion detection unit detects the preset motion of the forklift, the motion detection unit sends a reading instruction to the first tag reader. After receiving the reading instruction, the first tag reader turns on (ie, starts emitting a signal) and then reads the first tag to obtain a reading result.

[0121] 902. The communication unit sends the action information of the preset action and the first tag reading result to the warehouse management device.

[0122] In an optional embodiment, after detecting the above-mentioned preset action, the action detection unit may send the action information of the preset action to the communication unit. The action information may be an action type or action description information. Exemplarily, the action types include two types: a forklift picks up an inventory object and a forklift puts down an inventory object.

[0123] First Tag Reading Result After the tag reading is performed to obtain the first tag reading result, the first tag reading result may be sent to the communication unit.

[0124] The communication unit may send the action information of the preset action and the first tag reading result to the warehouse management device through a network.

[0125] 903. The warehouse management device performs corresponding processing according to the first tag reading result and the action information of the preset action.

[0126] The warehouse management device may perform operation behavior control and / or operation record according to the first tag reading result and the action information of the preset action.

[0127] In some embodiments, the warehouse management device verifies the current operating behavior of the forklift based on the reading result of the first tag and the action information of the preset action to determine whether the operating behavior is allowed; when the verification fails (that is, the operating behavior is allowed), the warning unit on the forklift is controlled to sound an alarm or the on-board computer on the forklift is controlled to display an alarm message; when the verification passes, no operation is required, at this time, the warning unit does not sound an alarm and the on-board computer does not display an alarm message.

[0128] When verifying the current operation behavior of the forklift, it can be executed in combination with the existing warehouse management data to determine whether the operation behavior is permitted. The specific implementation will be described in detail in the following embodiments.

[0129] In some embodiments, the warehouse management device generates an operation record of the inventory object according to the first tag reading result and the action information of the preset action. The specific implementation will be described in detail in the following embodiments.

[0130] In the technical solution provided in the embodiment of the present application, an action detection unit is provided on the forklift, and the action detection unit is used to detect the preset action of the forklift on the inventory object. When the action detection unit captures the preset action, it will automatically trigger the first tag reader to read the tag and report the tag reading result to the warehouse management device. The warehouse management device automatically performs the processing related to warehouse management according to the tag reading result and the action information of the preset action, such as: operation control or operation record. In other words, through the setting of the action detection unit and the tag reader on the forklift and the inventory tag on the inventory object, the warehouse management device can timely capture the operation behavior of the forklift on the inventory object, thereby improving the accuracy of warehouse management.

[0131] In some embodiments, the storage system further includes a warehouse; the warehouse includes a cargo space for storing the inventory object, and the cargo space is provided with a cargo space label; when the forklift picks up the inventory object from the cargo space or the forklift puts down the inventory object on the cargo space, the cargo space label is located within a preset reading range (i.e., an effective reading range) of the first tag reader. Note: When the tag is located within the preset reading range of the tag reader, the signal strength of the tag information read by the tag reader for the tag is greater than or equal to a preset strength threshold, and when the tag is located outside the preset reading range of the tag reader, the signal strength of the tag information read by the tag reader for the tag is less than the preset strength threshold. When the signal strength of the tag information read by the tag reader for the tag is less than the preset strength threshold, the tag reader determines that there is no reading result for the tag.

[0132] Optionally, in the above 903, “the warehouse management device performs corresponding processing according to the first tag reading result and the action information of the preset action” can be implemented by the following steps:

[0133] 9031. When the first label reading result includes the object label information and the cargo location label information, the warehouse management device determines the current operation behavior of the forklift for the inventory object from the shelving behavior and the de-shelving behavior according to the action information of the preset action.

[0134] In actual applications, when a forklift is loading (unloading) a shelf, the object tag on the loading (unloading) object and the cargo location tag on the loading (unloading) cargo location will be simultaneously located within the effective identification range of the forklift's first tag reader. In other words, when the first tag reader on the forklift can read the object tag information and the cargo location tag information at the same time, it indicates that the forklift is performing a loading or unloading action. Furthermore, when the preset action detected by the action detection unit is the action of the forklift lifting the inventory object, it indicates that the forklift's current operation action for the inventory object is unloading action; when the preset action detected by the action detection unit is the action of the forklift putting down the inventory object, it indicates that the forklift's current operation action for the inventory object is loading action.

[0135] When the first tag reading result includes the object tag information and the cargo location tag information and the preset action is the action of the forklift picking up the inventory object, it can be determined that the current forklift operation behavior is the destocking behavior. When the first tag reading result includes the object tag information and the cargo location tag information and the preset action is the action of the forklift putting down the inventory object, it can be determined that the current forklift operation behavior is the putting on the shelf behavior.

[0136] 9032. The warehouse management device performs corresponding processing according to the operation behavior.

[0137] In some embodiments, the warehouse management device generates an operation record for the operation behavior based on the object label information and the cargo location label information.

[0138] When the above operation behavior is a shelf-putting behavior, a shelf-putting record is generated, wherein the shelf-putting location recorded in the shelf-putting record is the location, and the recorded shelf-putting object is the inventory object. In addition, a binding relationship between the inventory object and the location can be established, and the location management information, such as the location status, can be updated according to the binding relationship.

[0139] When the operation behavior is a delisting behavior, a delisting record is generated, wherein the delisting location recorded in the delisting record is the location, and the delisting object recorded is the inventory object. In addition, the binding relationship between the inventory object and the location can be released, and the location management information, such as the location status, can be updated.

[0140] That is to say, the technical solution provided by the embodiment of the present application can automatically generate operation records when the preset action of the forklift is automatically recognized, which helps to improve the efficiency of digital inventory flow. In addition, the warehouse staff (such as forklift drivers) are unaware of the digital inventory flow process, that is, the digital inventory flow can be realized without the need for additional operations by the staff.

[0141] As an option, the warehouse management device may add the above operation record to the inventory circulation record of the inventory object as a record point in the inventory circulation record of the inventory object.

[0142] In order to strengthen warehouse management, cameras for collecting videos can be set up near cargo locations in the warehouse. The shooting areas (i.e., field of view) of different cameras can cover different cargo location areas. A correspondence between cargo locations and cameras can be established in advance, where the shooting area of ​​each camera covers the area where the corresponding cargo location is located. In order to save hardware resources, the shooting area of ​​one camera can cover multiple cargo location areas.

[0143] Generally speaking, these cameras collect data continuously for 24 hours, which means that the amount of video is very large. When a certain operation in the warehouse is subsequently traced back to history, the warehouse management personnel need to extract the video clips related to the operation from a large amount of video resources, which consumes a lot of time and manpower. In order to solve or partially solve this problem, in some embodiments, the above method may also include the following steps:

[0144] 904. The warehouse management device obtains a first video clip shot by a camera corresponding to the cargo location within a first target time period.

[0145] The moment when the action detection unit detects the preset action is a first target moment, and the first target moment is within the first target period. For example, the first target moment is a middle time point of the first target period.

[0146] Exemplarily, the first target time may be sent by the communication unit to the warehouse management device.

[0147] Exemplarily, the first target time is derived by the warehouse management device according to the reception time of receiving the first tag reading result. When the network delay is negligible, the warehouse management device may determine the reception time as the first target time.

[0148] Among them, the shooting area of ​​the camera corresponding to the cargo location covers the area where the cargo location is located.

[0149] 905. The warehouse management device stores the operation record and the first video clip in an associated manner.

[0150] In an optional implementation, the warehouse management device establishes an association relationship between the operation record and the first video segment. Exemplarily, a record number of the operation record and a segment identifier of the first video segment may be generated; and an association relationship between the record number and the segment identifier may be established. The warehouse management device stores the operation record, the first video segment, and the association relationship between the operation record and the first video segment. Exemplarily, the operation record, the first video segment, and / or the association relationship between the operation record and the first video segment may be stored in an object storage service (OSS).

[0151] In this way, the video clip corresponding to any operation record can be found based on the association relationship, which helps to quickly trace back history.

[0152] In some other embodiments, the forklift is also provided with a warning unit. In the above 903, "the warehouse management device performs corresponding processing for the operation behavior" can be implemented by the following steps:

[0153] 9033. The warehouse management device verifies the operation behavior according to the first tag reading result and the warehouse management data.

[0154] Among them, the warehouse management data may include but is not limited to: management information of each cargo location, the functional area to which each cargo location belongs, the type of goods each functional area is responsible for storing, the type of goods to which each inventory object belongs, the warehouse entry form, the warehouse exit form and the shift form. Among them, the management information of each cargo location may include: the current status of the cargo location, for example: occupied status, pre-locked status (or pre-occupied status). Among them, the occupied status means that the cargo location has stored inventory objects, and the pre-locked status means that although the cargo location does not currently store inventory objects, it has been pre-locked. Among them, the warehouse entry form records the inventory objects that need to be stored, the warehouse exit form records the inventory objects that need to be shipped out, and the shift form records the inventory objects that need to be shifted.

[0155] When the first tag reading result includes the object tag information and the cargo location tag information, it indicates that the current operation behavior of the forklift is either a loading behavior or a unloading behavior.

[0156] When the forklift's current operation behavior is shelving, based on the warehouse management data, determine whether the above-mentioned cargo location has been pre-locked (occupied) and / or whether the above-mentioned inventory object meets the conditions for shelving in the functional area where the cargo location is located, and determine the verification result based on the judgment result.

[0157] In an optional implementation, management information related to the cargo space may be obtained from warehouse management data; and based on record information related to the cargo space, it is determined whether the cargo space has been pre-occupied.

[0158] In an optional implementation, based on warehouse management data, the target cargo type to which the above-mentioned inventory object belongs and the cargo type that the functional area where the above-mentioned cargo location is located is responsible for storing are determined; when the target cargo type is not the cargo type that the functional area where the above-mentioned cargo location is located is responsible for storing, it is determined that the inventory object does not meet the conditions for being put on the shelves in the functional area where the cargo location is located; when the target cargo type is the cargo type that the functional area where the cargo location is located is responsible for storing, it is determined that the inventory object meets the conditions for being put on the shelves in the functional area where the cargo location is located.

[0159] Exemplarily, when the cargo space is not pre-occupied, the verification result is passed; when the cargo space is pre-occupied, the verification result is failed.

[0160] Exemplarily, when the inventory object meets the condition of being put on the shelf in the functional area where the shelf is located, the verification result is passed; when the inventory object does not meet the condition of being put on the shelf in the functional area where the shelf is located, the verification result is passed.

[0161] Exemplarily, when the storage location is not pre-occupied and the inventory object meets the conditions for being put on the shelf in the functional area where the storage location is located, the verification result is passed; when the storage location is pre-occupied or the inventory object does not meet the conditions for being put on the shelf in the functional area where the storage location is located, the verification result is failed.

[0162] When the forklift's current operation behavior is to take down the item from the shelf, it can be determined whether the inventory object allows taking down the item from the shelf. If the inventory object allows taking down the item from the shelf, the verification result is passed; otherwise, the verification result is failed.

[0163] Exemplarily, it can be determined whether the inventory object is located in an outbound order or a transfer order; when the inventory object is located in an outbound order or a transfer order, it is determined that the inventory object is allowed to be taken off the shelf; when the inventory object is not located in an outbound order and is not located in a transfer order, it is determined that the inventory object is not allowed to be taken off the shelf.

[0164] 9034. If the verification fails, the warehouse management device controls the warning unit to issue a warning.

[0165] Exemplarily, the warning unit includes a warning light and a buzzer. If the verification fails, the warning light turns red and the buzzer emits an alarm sound (e.g., a buzzer). If the verification passes, the warning light turns green and the buzzer does not emit an alarm sound.

[0166] Exemplarily, the warehouse management equipment can also determine the flashing rules of the warning light and / or the beeping frequency of the buzzer according to the reason why the verification failed, and control the flashing of the warning light according to the flashing rules of the warning light and / or control the beeping of the buzzer according to the beeping frequency of the buzzer. In this way, the forklift driver can know the reason why the verification failed according to the flashing rules of the warning light and / or the beeping frequency of the buzzer, and take corresponding measures to solve it.

[0167] In this embodiment, the forklift driver can be reminded to adjust the operation through the warning, thereby avoiding the risk of inefficient rework or cargo damage or loss due to incorrect loading and unloading.

[0168] In actual applications, when a forklift performs loading and unloading, the first tag reader can read the object tag information of the loading and unloading objects and the cargo location tag information of the loading and unloading cargo locations, that is, the first tag reading result includes both the object tag information and the cargo location tag information. When the forklift picks up the inventory objects from the tallying area to start the warehousing task, the first tag reader can only read the object tag information of the inventory objects picked up by the forklift, that is, the first tag reading result includes the object tag information but does not include the cargo location tag information. When the forklift puts down the inventory objects on the truck or at the entrance of the truck to end the outbound task, the first tag reader can only read the object tag information of the inventory objects put down by the forklift, that is, the first tag reading result includes the object tag information but does not include the cargo location tag information.

[0169] Optionally, the above method may further include:

[0170] 906. When the first tag reading result includes object tag information but does not include any cargo location tag information and the preset action is an action of a forklift picking up the inventory object, the warehouse management device obtains a warehouse entry order.

[0171] Among them, the inventory objects that need to be put into storage are recorded in the inventory entry form.

[0172] 907. If the inventory object picked up by the forklift is not recorded in the warehouse entry form, the warehouse management device controls the warning unit to issue a warning.

[0173] If the inventory object picked up by the forklift is not recorded in the warehouse entry form, the warning light is controlled to light up red and the buzzer is controlled to emit an alarm sound (such as a buzzer); if the inventory object picked up by the forklift is recorded in the warehouse entry form, the warning light is controlled to light up green and the buzzer is controlled not to emit an alarm sound.

[0174] Through the warning, the forklift driver can be reminded to adjust the operation to avoid warehousing errors.

[0175] Optionally, the above method may further include:

[0176] 908. When the first tag reading result includes object tag information but does not include any cargo location tag information and the preset action is an action of a forklift putting down the inventory object, the warehouse management device obtains a delivery order.

[0177] 909. If the delivery note does not record the inventory object dropped by the forklift, the warehouse management device controls the warning unit to issue a warning.

[0178] If the delivery note does not record the inventory object dropped by the forklift, the warning light is controlled to light up red and the buzzer is controlled to emit an alarm sound (such as a buzzer); if the delivery note records the inventory object dropped by the forklift, the warning light is controlled to light up green and the buzzer is controlled not to emit an alarm sound.

[0179] Through the warning, the forklift driver can be reminded to adjust the operation to avoid warehouse errors.

[0180] It should be noted that, in the shelving scenario, when the forklift driver fails to place the inventory object correctly, the first tag reader is also unable to identify the shelf location label because the location label of the shelf location is not within the effective identification range of the first tag reader. That is to say, in this case, the first tag reading result includes the object label information but does not include any location label information. The warning can prompt the forklift driver to adjust the placement of the inventory object, thereby avoiding damage caused by the falling of the inventory object due to inappropriate placement of the inventory object.

[0181] In order to strengthen warehouse management, an electric gate and a sensing device are provided at the passageway of the warehouse. The sensing device includes a sensor and a second tag reader. The sensor is used to detect whether an object enters the sensing area corresponding to the sensing device. In some embodiments, the passageway may include the entry port, exit port and / or the connecting port between different inventory areas mentioned in the above embodiments. It should be noted that when a warehouse is provided with multiple inventory areas, connecting ports may be provided between different inventory areas.

[0182] The method may further comprise the following steps:

[0183] 910. When the sensor detects that an object has entered the sensing area, the sensor triggers the second tag reader to send a second tag reading result to the warehouse management device.

[0184] The sensor includes but is not limited to a distance sensor or a pressure sensor.

[0185] Exemplarily, the distance sensor or the pressure sensor may be disposed on the ground of the sensing area.

[0186] Exemplarily, the sensing device is a sensing door, and the distance sensor can be arranged on the sensing door.

[0187] In an optional implementation, when the pressure sensor detects that the pressure increases and is greater than a preset pressure threshold, it is determined that an object has been detected entering the sensing area.

[0188] In another optional implementation, when the distance sensor detects that the distance becomes smaller and is less than a preset distance threshold, it is determined that an object is detected to enter the sensing area.

[0189] In some embodiments, when the sensor detects that an object has entered the sensing area, the sensor sends a reading instruction to the second tag reader, and the second tag reader is turned on after receiving the reading instruction to read the second tag to obtain a reading result.

[0190] 911. When the second tag reading result includes the object tag information, the warehouse management device determines whether the inventory object meets the gate-through condition based on the object tag information and the warehouse management data.

[0191] When the second tag reading result includes object tag information, it indicates that the inventory object identified by the object tag information enters the above-mentioned sensing area.

[0192] When the channel entrance is the entry entrance, an entry list can be obtained. When the entry list records the inventory object entering the sensing area, it is determined that the inventory object meets the door-passing conditions; otherwise, it does not meet the door-passing conditions.

[0193] When the channel entrance is an outbound exit, an outbound order can be obtained. When the outbound order records an inventory object that has entered the sensing area, it is determined that the inventory object meets the pass-through conditions; otherwise, it does not meet the pass-through conditions.

[0194] When the passageway is a connecting port between different inventory areas, a shift order can be obtained. When the shift order records an inventory object entering the sensing area, it is determined that the inventory object meets the pass-through conditions; otherwise, it does not meet the pass-through conditions.

[0195] 912. When the inventory object meets the door-passing condition, the warehouse management device controls the electric gate to open.

[0196] The warehouse management equipment can send a door opening command to the controller of the electric gate, and the controller controls the electric gate to open (for example: controlling the electric sliding door to move to open the passage) to allow forklifts to pass.

[0197] When the inventory object does not meet the door-passing condition, since the electric gate is in a closed state by default, the warehouse management device does not need to perform any operation.

[0198] The technical solution provided in this embodiment can achieve effective physical isolation of the entry or exit channels of goods, which helps to improve the effectiveness of inventory management.

[0199] Optionally, the above method may further include the following step 916:

[0200] 913. When the inventory object does not meet the door-passing condition, the warehouse management device controls the warning unit on the sensing device to issue an alarm.

[0201] For specific alarm forms, please refer to the corresponding contents in the above embodiments, which will not be repeated here.

[0202] In order to improve the integrity of inventory flow records, a pass-through record may also be generated. That is, the above method may also include:

[0203] 914. When the inventory object meets the gate-pass condition, the warehouse management device generates a gate-pass record.

[0204] The door-passing object recorded in the door-passing record is the inventory object.

[0205] Exemplarily, when the channel entrance is an entry entrance, an entry door-pass record is generated; when the channel entrance is an exit entrance, an exit door-pass record is generated; and when the channel entrance is a connecting port between different inventory areas, a shift door-pass record is generated.

[0206] The door-passing record may also record the passageway passed through (eg identification information of the passageway).

[0207] Optionally, the door-to-door record may be added to the inventory flow record of the inventory object.

[0208] In order to further strengthen warehouse management, cameras for collecting videos can be set up near the passageways in the warehouse. Different cameras cover different passageway areas.

[0209] In some embodiments, the above method may further include:

[0210] 915. The warehouse management device obtains a second video clip shot by the camera corresponding to the channel entrance within a second target time period.

[0211] The second target time refers to the time when the sensor detects that an object enters the sensing area, and the second target time is within the second target period. For example, the second target time is the middle time point of the second target period.

[0212] Among them, the shooting area of ​​the camera corresponding to the channel entrance covers the area where the channel entrance is located.

[0213] 916. The warehouse management device stores the door-pass record and the second video clip in association with each other.

[0214] Optionally, the warehouse management device establishes an association relationship between the transition record and the second video clip. Exemplarily, a correspondence relationship is established between the record identifier of the transition record and the clip identifier of the second video clip. The warehouse management device stores the transition record, the second video clip, and the association relationship between the transition record and the second video clip. Exemplarily, the transition record, the second video clip, and / or the association relationship between the transition record and the second video clip may be stored in OSS.

[0215] In a warehouse operation scenario, goods usually enter or leave the warehouse in batches. In order to improve the efficiency of goods leaving or entering the warehouse. The above method may also include the following steps:

[0216] 917. The warehouse management device determines the in-transit batch to which the inventory object belongs.

[0217] In the inbound scenario, the inbound batch is also the inbound batch. In the outbound scenario, the inbound batch is also the outbound batch. In the shift scenario, the inbound batch is also the shift batch.

[0218] Exemplarily, a plurality of inventory objects to be put into storage recorded in a storage entry form is a storage entry batch.

[0219] Exemplarily, a plurality of inventory objects to be shipped out recorded in a shipping order is a shipping batch.

[0220] Exemplarily, a plurality of inventory objects to be shipped out recorded in a transfer order is a transfer batch.

[0221] When the channel opening is a storage entrance, the warehouse management device determines the storage batch to which the inventory object belongs.

[0222] When the channel opening is a warehouse exit, the warehouse management device determines the warehouse exit batch to which the inventory object belongs.

[0223] When the passage opening is a communication port between different inventory areas, the warehouse management device determines the shift batch to which the inventory object belongs.

[0224] 918. The warehouse management device determines whether there are other inventory objects in the batch that have not been through the door.

[0225] According to the door-passing record, it can be determined whether there are other inventory objects in the door-passing batch that have not been passed through the door.

[0226] 919. When the other inventory objects exist, the warehouse management device turns on the normally open mode of the electric gate.

[0227] When there are other goods, the warehouse management device sends a normally open instruction to the controller of the electric gate, and the controller turns on the normally open mode of the electric gate according to the normally open instruction.

[0228] 920. After the electric gate is turned on in the normally open mode, when the batch of goods passing through the gate has completed passing through the gate, the warehouse management device controls the electric gate to close.

[0229] Whether the gate-passing batch has completed gate-passing can be determined according to the gate-passing record. Exemplarily, when the channel entrance is an entry gate, when each inventory object in the entry gate-passing batch has a corresponding entry gate-passing record, it is determined that the entry gate-passing batch has completed gate-passing. Exemplarily, when the channel entrance is an exit gate, when each inventory object in the exit gate-passing batch has a corresponding exit gate-passing record, it is determined that the exit gate-passing batch has completed gate-passing.

[0230] When the warehouse management device determines that the batch has completed the gate passing according to the gate passing record, the warehouse management device sends a closing instruction to the controller of the electric gate. The controller closes the electric gate (for example, moves the electric sliding door to block the passage) based on the closing instruction.

[0231] In this way, when the forklift is moving the same batch of goods, it only needs to wait for the gate to open at the electric gate when moving the first goods in the batch. It does not need to wait for the gate to open at the electric gate when moving other goods in the batch, which effectively improves the working efficiency of the forklift and improves the efficiency of outbound or inbound storage.

[0232] It should be noted that when the forklift carries other goods in the same batch (not the goods carried for the first time) through the passage, the above steps 910, 911 and 914 will also be triggered to execute, that is, a pass-through record will be generated for the other goods. It should be noted that when it is determined in step 911 that the pallet carried by the forklift does not meet the pass-through conditions, the warehouse management device can control the warning unit on the sensing device to issue a warning.

[0233] Optionally, the above method may further include the following steps:

[0234] 921. After the electric gate is turned on in the normally open mode, if no new door passing record is generated within a preset time period, the warehouse management device controls the electric gate to close.

[0235] The duration of the preset time period can be set according to actual needs, and the embodiment of the present application does not specifically limit this. For example, the duration of the preset time period is 10 minutes or 30 minutes.

[0236] When no new door-passing record is generated within a preset time period, it indicates that the door-passing task of the batch of goods is abnormally interrupted. In order to improve the isolation effectiveness of the entry / exit channel, the warehouse management device controls the electric gate to close.

[0237] In this embodiment, when the gate-passing task of a batch of goods is abnormally interrupted, the electric gate can be closed in time instead of being in an open state for a long time.

[0238] In the warehouse operation scenario, the warehousing process at least involves the steps of entering the warehouse through the door and putting on the shelves; the outbound process at least involves the steps of taking off the shelves and passing through the door for outbound delivery; the shifting process at least involves the steps of taking off the shelves, shifting through the door and putting on the shelves. The warehousing management method provided in the embodiment of the present application can be used to record the warehousing process, shifting process and processing process, and form a complete and refined inventory flow record from a full-link perspective and multi-data dimension statistical method. In addition, the inventory data (the binding relationship between the pallet and the cargo location, the number of goods that have been warehoused in the current batch) and the cargo location data (such as the cargo location status) can also be updated according to the operation records in the above embodiments to achieve refined inventory data and improve the efficiency of finding goods.

[0239] In the embodiment of the present application, by using RFID technology to reuse the existing facilities in the warehouse and transform them into the Internet of Things, a combination of software and hardware is used to achieve precise control and management of goods entering and leaving the warehouse, thereby improving the efficiency and accuracy of warehouse management, and solving the problems of low efficiency of manual management, easy loss of paper data, and incomplete supervision capabilities in traditional warehouse management systems.
