The hazardous waste sent into the closed type storehouse 1 is mainly solid waste or liquid waste and pasty waste.
After receiving the warehousing information, the controller performs the following warehousing control: setting a storage position; selecting an automatic cruise forklift; calculating a path; and (5) controlling warehousing operation. The above warehousing control process is described in detail below.
Setting a storage position: the controller reads an inventory information table stored in a database, the table comprises preset shelf area setting information which uses one or some shelves to store preset types of dangerous wastes, the waste type information in the RFID label information in the warehousing information is compared with shelf area setting information (comprising information such as shelf area coordinates, shelf IDs, shelf positions, types of goods stored on shelves and the like) in the inventory information table one by one, when the waste type information is the same as the information of the types of goods stored on shelves, the shelf area is indicated to be used for storing the types of wastes, the warehoused wastes are determined to be stored in the shelf area, after the shelf area is determined, the controller reads the related inventory information of the shelf area, determines which shelf has spare storage space, after the determination, selects one shelf as a target shelf, and sets the storage space which is free on the target shelf and is used for storing packing cases as a target storage space, and finishing the setting of the storage position. The shelf area is set according to the following rules: 1. compatibility rules: incompatible dangerous wastes can not be stored in the same shelf, for example, acid and alkali can not be placed on the same shelf, so as to avoid chemical reaction, explosion or generation of extremely toxic gas; 2. classification storage rules: after the dangerous wastes with similar chemical properties are classified, such as acid, alkali, halogen, mercury and the like, the similar dangerous wastes or compatible dangerous wastes are collectively stored on the same shelf or a plurality of adjacent shelves, and a shelf area of the compatible dangerous wastes is formed. A safe distance, e.g., over 10 meters, needs to be maintained between the areas of the racks where incompatible hazardous waste is stored.
Selecting an automatic cruise forklift: after the storage position is set, the controller broadcasts idle inquiry information to the automatic cruise forklift in the closed warehouse, the idle forklift receiving the inquiry information sends a response signal, the signal comprises an ID number, an idle state, the forklift position and the like of the forklift, after the controller receives the response signal, the controller determines which idle forklift is closest to the material inlet 13 according to the forklift position and the read map information of the closed warehouse in the database, and selects the idle forklift closest to the material inlet 13 as the automatic cruise target forklift to perform warehousing operation.
Path calculation: after the automatic cruise forklift is selected, the controller inquires a map of the closed warehouse stored in the database, and calculates a driving path according to the position (coordinates) of the goods shelf and the position of the automatic cruise target forklift.
And (3) warehousing operation control: after the path calculation is finished, the controller sends a warehousing operation instruction to the target forklift, and the instruction comprises the following steps: the storage method comprises the steps of a feeding port ID where the warehousing packing box is located, a warehousing packing box ID, a target shelf ID, a target storage space ID and a driving path. After the target forklift receives the warehousing operation instruction, the control unit of the target forklift controls the forklift to complete warehousing operation according to the warehousing operation instruction:
after receiving the warehousing operation instruction, the control unit of the automatic cruise target forklift 12 controls the forklift to automatically travel to the position near a material inlet of a warehousing packing box according to a traveling path, when the control unit approaches the material inlet, an RFID reader of the target forklift 12 reads an RFID label on the material inlet to obtain a material inlet ID, the forklift control unit compares the ID with the material inlet ID in the warehousing operation instruction, if the ID is consistent with the material inlet ID, the material inlet operation is carried out, and if the ID is inconsistent with the material inlet ID, the forklift is controlled to stop and give an alarm to the controller until a further instruction of the controller is received, and then the forklift works according to the instruction. Under the condition of consistency, the control unit judges whether the distance between the forklift and the feeding port is close enough or not through the distance between the forklift and the feeding port detected by the distance sensor of the target forklift, and when the distance between the forklift and the feeding port reaches a set threshold value, the control unit controls the forklift to stop moving; the RFID reader of the target forklift reads the RFID label of the warehousing packing box loaded on the waste conveying device 23 entering the feeding port, when the control unit judges that the read label ID is the same as the warehousing packing box ID contained in the warehousing operation instruction, the control unit controls the forklift to insert and take the packing box from the waste conveying device 23, and the packing box is driven to the target shelf according to the driving path and is filled into the target storage space: and when the target forklift is controlled to automatically drive to the vicinity of the target shelf according to the driving path, the RFID reader of the target forklift reads the RFID tag on the target shelf to obtain a target shelf ID, the forklift control unit compares the ID with the target shelf ID in the warehousing operation instruction, if the ID is consistent with the target shelf ID, loading operation is carried out for feeding, if the ID is inconsistent with the target shelf ID, the operation is stopped, an alarm is sent to the controller, and the target forklift works according to the instruction after receiving a further instruction of the controller. Under the condition of consistency, the control unit of the target forklift judges whether the distance between the forklift and the goods shelf, which is detected by the distance sensor, is close enough, and when the distance between the forklift and the goods shelf reaches a set threshold value, the control unit controls the forklift to stop moving; and the control unit compares the ID of the storage space on the goods shelf with the ID of the target storage space in the warehousing operation instruction, if the ID of the storage space on the goods shelf is consistent with the ID of the target storage space in the warehousing operation instruction, feeding operation is carried out, the target forklift is controlled to load the packing box into the target storage space of the target goods shelf, and if the ID of the storage space on the goods shelf is inconsistent with the ID of the target storage space in the warehousing operation instruction, the forklift is controlled to stop and send an alarm to the controller until a further instruction. After the loading is finished, the control unit sends the loading finishing information to the controller, and the controller updates the inventory information table in the database: and adding the warehousing time, warehousing type, weight, storage position and the like of the packing box in the inventory information table.
