All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a stereoscopic warehouse system which comprises a data processing module, a material warehousing module, a material delivery module, a finished product warehousing module, a finished product delivery module, a goods location and data task management module, a hardware monitoring module and an AGV, wherein the material warehousing module, the material delivery module, the finished product warehousing module, the finished product delivery module, the goods location and data task management module, the hardware monitoring module and the AGV are.
The material warehousing module is used for detecting a warehousing request signal of the previous process after the previous process is finished, establishing a warehousing task, and scheduling the AGV to move the material to the designated shelf.
Specifically, the step of detecting the warehousing request signal of the previous process by the material warehousing module is as follows: after the materials are processed in the last procedure in the workshop, finished products are placed in the tray to a specified position, and the action of warehousing signals is triggered. The material warehousing module schedules the action of placing the materials on the designated shelf by the AGV, the material warehousing module reserves a position, then sends an AGV scheduling instruction to the upper-layer system, and conveys the materials at the position of the material warehousing request signal to the reserved goods space. Reserve goods position indicates: the material warehousing module acquires an idle goods position of the data processing module, and waits for the data processing module if no idle goods position exists; and if the data processing module returns the idle goods position, the material warehousing module writes the information of reserving the current idle goods position into the data processing module. The data processing module reserves the goods space appointed by the material warehousing module. The upper system refers to a workshop management system, such as an MES system, or an AGV scheduling system, and is particularly characterized by being capable of scheduling the execution of the AGV. The term "AGV schedule" refers to the starting and ending locations of AGVs executing tasks and the data content of what actions should be performed at the locations sent to other systems via WEB API, TCP/IP or other interface.
More specifically, the step of conveying the material to the reserved goods space at the position of the signal requesting the material to enter the warehouse comprises the following steps: when the AGV reaches the starting point position and returns the tray ID, the upper layer system returns the task tray ID through calling a data processing module interface, the tray ID is fed back to the data processing module, the data processing module checks whether the ID is correct, if the ID is correct, a correct signal of the upper layer system is returned, and if the ID is wrong, an error signal is returned. After the AGV finishes the task, the upper-layer system returns a task completion signal to the data processing module, and the data processing module can modify the task and the goods position state. And (3) putting the current tray in an inventory state, and completing the warehousing task (as shown in the attached figure 1).
The material warehouse-out module is used for establishing warehouse-out tasks through warehouse-out interfaces triggering the material warehouse-out module when materials are needed in the process, and dispatching the AGV to deliver the materials to the appointed machine station position.
Specifically, when the material is needed in the process of the material delivery module, the upper layer scheduling system receives a signal of the material needed in the production workshop by triggering the delivery interface of the material delivery module. And then the upper layer system informs the specific tray number through the material warehouse-out module interface. After the tray number of the material warehouse-out module is informed, the material warehouse-out module inquires whether a specified tray number exists in a warehouse or not through the connection data processing module, whether the states are consistent or not is judged, then the inquiry result is fed back to a dispatching AGV instruction in the material warehouse-out module of the upper system, and the material warehouse-out module sends an AGV dispatching instruction to the upper system after inquiring that the specified tray number exists in the warehouse.
More specifically, the ' material is sent to the designated machine station position ' in the material warehouse-out module, that is, when the AGV reaches the starting point position and returns the tray ID, the upper layer system returns the task tray ID ' interface by calling the data processing module, and feeds the tray ID back to the data processing module, and the data processing module checks whether the ID is correct, and if the ID is correct, returns a correct signal of the upper layer system, and if the ID is wrong, returns an error signal. After the AGV finishes the task, the upper-layer system returns a task completion signal to the data processing module, and the data processing module can modify the task and the goods position state. And (3) enabling the current tray to be in the warehouse-out state, and completing the warehouse-out task (as the attached figure 1).
The finished product warehousing module is mainly used for establishing warehousing tasks through an upper-layer system trigger interface after the materials are processed in the process, distributing idle goods positions to the finished materials, and scheduling the AGV to warehouse the processed materials of the appointed machine to the distributed goods positions. Specifically, the 'triggering of the interface by the upper system after the material processing in the process is completed in the finished product warehousing module' means that when the upper system needs to store the completed material in the warehouse, the upper system calls the interface of the finished product warehousing module to request warehousing action. The spare goods positions distributed by the finished product warehousing module are the same as those distributed by the material warehousing module. The 'dispatching AGV' in the finished product warehousing module means that the finished product warehousing module sends an AGV dispatching instruction to an upper-layer system after distributing an idle goods position. The finished product warehousing module refers to the action of warehousing the processed materials of the appointed machine station into the allocated goods space, and refers to the action of returning the tray ID when the AGV reaches the starting point position, the upper layer system returns a task tray ID interface by calling the data processing module, the tray ID is fed back to the data processing module, the data processing module checks whether the ID is correct, if so, a correct signal of the upper layer system is returned, and if not, an error signal is returned. After the AGV finishes the task, the upper-layer system returns a task completion signal to the data processing module, and the data processing module can modify the task and the goods position state. And (4) putting the current tray in stock, and completing the warehousing task (as shown in the attached figure 1).
The finished product ex-warehouse module is mainly used for establishing an ex-warehouse task by calling an interface of the finished product ex-warehouse module when the next process needs materials, and scheduling the AGV to send the processed materials to an outlet. Specifically, the 'calling the interface of the module when the next process needs the material' in the finished product delivery module refers to the action of calling the interface of the finished product delivery module when the upper system acquires a signal requesting delivery sent by the next process or the WEB front end. The finished product ex-warehouse module checks whether the requested pallet is in the warehouse after receiving the instruction, and returns a check result to the upper-layer system. The 'dispatching AGV' in the finished product delivery module means that: and the finished product delivery module sends an AGV dispatching instruction to the upper-layer system after distributing the idle goods position. The 'conveying the processed materials to an outlet' in the finished product delivery module means that: when the AGV reaches the starting point position and returns the tray ID, the upper layer system returns the task tray ID through calling a data processing module interface, the tray ID is fed back to the data processing module, the data processing module checks whether the ID is correct, if the ID is correct, a correct signal of the upper layer system is returned, and if the ID is wrong, an error signal is returned. After the AGV finishes the task, the upper-layer system returns a task completion signal to the data processing module, and the data processing module can modify the task and the goods position state. And (3) enabling the current pallet goods position to be in an idle state, and completing the warehouse-out task (as the attached figure 1).
The cargo space and data task management module is mainly a module which is operated when manual intervention is needed when an exception occurs. Specifically, the cargo space and task management module comprises: and modifying the state of the goods position, manually completing the task, canceling the task, and retransmitting the AGV dispatching instruction. Each processing method corresponds to an interface, and each interface is connected with a data processing module to realize respective functions by modifying the underlying data (as shown in fig. 2).
The modification of the state of the goods position means that when the operation fails and the automatic operation cannot be performed, the goods position can be emptied by calling a modified goods position state interface or manually recorded into a certain tray. After the modification state interface is called, the modification cargo space state interface transmits the received information to the data processing module, and the data processing module modifies the bottom cargo space data.
The manual task completion means that when the operation fails and the automatic operation cannot be performed, the specified task can be manually completed by calling a manual task completion interface. The manual completion task interface checks the state of the current task after receiving the information, does not do any operation if the task is completed or does not exist, and transmits the received data to the data processing module if the task is in operation, and the data processing module modifies the underlying task data.
The task cancellation means that when the operation fails and the automatic operation cannot be performed, the designated task can be cleared from the task list by calling a task cancellation interface. The task canceling interface checks the state of the current task after receiving the information, does not do any operation if the task is completed or does not exist, and transmits the received data to the data processing module if the task is in operation, and the data processing module modifies the underlying task data.
And the retransmission AGV dispatching instruction indicates that the operation fails and cannot be automatically operated, and the retransmission AGV dispatching instruction interface is called to send the AGV dispatching instruction to the upper-layer system again. And the task resending interface checks the state of the current task after receiving the information, does not do any operation if the information is completed or the record shows that the AGV task is successfully sent, otherwise, transmits the received data to the data processing module, and modifies the data of the bottom layer task by the data processing module to resend the AGV task.
The hardware monitoring module is used for giving an alarm when the user moves the materials on the goods shelf or puts the materials on the goods shelf manually. The hardware monitoring module comprises three parts, namely a data reading part, a data analysis part and a monitoring interface (shown in figure 3). The data reading means that the hardware monitoring module circularly reads the PLC basic parameters from the data processing module, then is connected with the PLC to read PLC element data, and uploads the PLC element data to the data processing module for storage. The data analysis means that the data analysis program checks whether the data uploaded by the data reading program each time is matched with the inventory state of the tray position in the data processing module in real time, and if the data uploaded by the data reading program is not matched with the inventory state of the tray position in the data processing module, the data analysis program informs the monitoring interface to display the goods position with an incorrect state for a user. The monitoring interface receives the alarm uploaded by the data analysis program and the data needing to be reported to the user and displays the data in a billboard mode.

the data processing module receives tray ID a, and the check Task2 returns tray ID: a is correct. And then returns to the upper system to continue with Task2 signal.
After the AGV has carried tray A to the Machine1, the upper level dispatching system returns a completion signal to Task 2.
After the data processing module receives the completion signal of the Task2, the data processing module modifies the Task2 state to be complete and the position #1 state to be idle.
And the machine station sends a blanking signal to an upper layer system after the production is finished. The upper system receives the machine: and after the Machine1 requests a blanking signal, the upper layer system calls a finished product warehousing interface.
And after the finished product warehousing interface receives the request of the Machine1 for warehousing, inquiring whether a goods position is available for the data processing module, if so, reserving the goods position #3 for the data processing module, and establishing a Task 3.
The finished goods warehousing module sends the task to the upper system for shipment from the Machine1 to location #3 after the task is established.
After the upper system receives the scheduling task, the AGV is scheduled to go to a Machine No. 1 to take materials, and after the AGV reaches a Machine No. 1, the upper system returns a tray ID: A.
a, the data processing module receives that the Task3 returns the tray ID, and checks that the Task3 returns the tray ID: if A is correct, then a continue Task3 is sent to the upper level dispatch system, and the AGV transports tray A to position: after #3, the upper layer system returns a Task3 completion signal to the data processing module.
After the data processing module receives the Task3 completion signal, the data processing module modifies the Task3 state to completion and modifies the position #3 state to a finished product.
When the upper-layer system needs to deliver the tray A to the next process, a finished product delivery interface is called to deliver the tray A to a position # 4; when the finished product warehouse-out module receives the warehouse-out request of the tray A, the tray A is checked in the warehouse, and then a finished product warehouse-out Task4 is established.
And after the finished product ex-warehouse task is established, sending an ex-warehouse task for carrying the tray A from the position #3 to the position #4 to an upper-layer system.
After receiving the task, the upper layer system schedules the AGV to go to a position #3, the AGV reaches the position #3, and the upper layer system sends a tray ID A to the data processing module; and according to the fact that the processing module receives the Task4 to return the tray ID, A, the checking Task4 returns the tray ID: if A is correct, then a continue Task4 is sent to the upper level dispatch system, and the AGV transports tray A to position: after #4, the upper system returns a Task4 completion signal to the data processing module.
After the data processing module receives the Task4 completion signal, the data processing module modifies the Task4 state to completion and modifies the location #3 state to idle.
