The control unit is composed of a plurality of control pages, is connected with the vertical library equipment through an IP and is used for remotely controlling the vertical library equipment, and particularly, is connected with the vertical library equipment through the IP, and personnel inputs relevant parameters on the pages or clicks relevant buttons such as: reset, issue down to go to a specific location, clear task, etc. So that personnel can directly operate the equipment in the vertical warehouse without entering the vertical warehouse.
Specifically, in production, if a certain material is entered into wrong production information before entering a vertical warehouse, the wrong MES (manufacturing execution system) information is read by entering the vertical warehouse WMS (warehouse management system) and stored in a database, the product is just distributed when the next material is called out of the warehouse, when the goods are sent to the next production link, the materials are found to be different from the needed materials, at this time, people need to call the materials again, generally, a part of the production workshop has a spare material beside a station during production, and if the spare material is used at this time and a new material is not sent yet, the waiting or the drawing of a part of the new material from other stations is needed, so that the production efficiency is reduced and the time is wasted. For this situation, when personnel go out of the warehouse manually to correct production information after finding wrong materials; in one, it is to cope with emergency or, for example: WMS (warehouse management system) cannot normally generate the tasks of calling materials and leaving warehouse, and the conditions of requiring a large number of empty trays to be transferred to other vertical warehouses, communication interruption of WMS (warehouse management system) and WCS (warehouse control system), etc. The invention aims at the emergency situation to add the stock module, and the stock module can enable personnel to manually operate the stock to issue a stock instruction by reading the synchronous stock data of the WMS (warehouse management system) and storing the synchronous stock data into the local database, so that the production downtime caused by the emergency situation is reduced.
Specifically, referring to fig. 2, a flowchart is shown for implementing a device, and before operation, IP configuration of each device in the vertical library is performed in the WCS warehouse control system, and the configuration is completed to check whether the network, the IP, and the computer in which the WCS warehouse control system is located can normally communicate. Meanwhile, a database is installed on a computer where the WCS warehouse control system is located and is used for storing monitoring data of the WCS warehouse control system and data of issuing instructions
Monitoring function: the equipment hardware of the vertical warehouse is connected through a background program of the WCS (warehouse control system) in an IP connection mode, after the equipment hardware is successfully connected, a person can check the operation parameters, the equipment states or the alarm information of the equipment hardware of the vertical warehouse, and the person judges whether the equipment in the vertical warehouse is normal or not or the corresponding processing mode during alarm according to the display information.
Control function: the hardware of each device in the vertical library is connected through a background program of the WCS (warehouse control system) in an IP connection mode, and after the connection is successful, a person operates a certain device in the vertical library according to the information of the monitoring page, such as: the stacker has the advantages that the alarm fork of the stacker cannot stretch out and draw back in place, a person resets the fork through the page, inputs corresponding information or clicks a corresponding button WCS (warehouse control system) to instruct the PLC (programmable controller) (the instruction includes the instruction of advancing, retreating, lifting of a cargo carrying platform, forward rotation and reverse rotation of a conveying line and the like) of the stacker, the PLC (programmable controller) receives the instruction, executes the instruction and returns successful receiving, and a background program of the WCS (warehouse control system) acquires successful information and displays the successful information on the page.
Inventory function: when the WMS warehouse management system cannot normally issue tasks or the production information is wrongly input, the corresponding outlet of a certain inventory selection can be selected through the inventory page, and specified delivery is performed.
Personnel control the condition of the vertical warehouse equipment: when the equipment is in normal operation, the alarm is suddenly given, the equipment stops operating, and a maintainer or a vertical manager goes to the page to check the state of the current alarm equipment. Displaying personnel to operate the control module according to the monitoring information of the page, for example: the stacker fork empty triggers an alarm, personnel clear corresponding stock in a WMS (warehouse management system), delete corresponding tasks, and personnel clear the stacker self task on the page and press a reset button to enable the stacker to resume normal execution of the next task. In order to safely enclose the vertical warehouse in a factory, a safety door is arranged, all devices in the vertical warehouse can alarm as long as a person opens the safety door, and the person only needs to press the corresponding reset button next to the page at the moment, and the related devices receive the instruction to recover to be normal.
Preferably, the device provided in the library module includes: RGV rail guided vehicles, stackers, conveyor line access interface devices.
Specifically, WCS (warehouse control system) monitors and controls devices such as or notes:
stacker (fork or string bar as picking device): the stacker used in the vertical warehouse is generally in rail operation and rail-free operation; the operation mode is as follows: the whole is moved left and right according to the instruction, the cargo carrying platform is moved up and down, and the execution is to execute specific carrying cargo according to the instruction issued by the WCS (warehouse control system), such as: the WCS (warehouse control system) transmits a warehouse-in command stacker to receive the warehouse-in command, then moves to an inlet to extend out of a fork to pick up goods, and the fork is retracted to process whether to lift the cargo bed according to a PLC (programmable logic controller) of the command stacker.
The actual use of the stacker can form a closed loop flow together with WMS (warehouse management system), WCS (warehouse control system) and stacker PLC (programmable logic controller). The following exemplifies the case of operating the stacker when an abnormality occurs:
(1) The left or right ultra-wide alarm of the cargo loading platform generally shows that when the cargo is taken or put, the fork is not retracted to the correct position, and the fork can protrude out of the width of the stacker, and serious production accidents can be caused by collision of the cargo if the stacker is continuously walked. If the situation needs personnel to enter the vertical warehouse to manually operate related programs on a stacker screen, starting a manual mode to control the fork to stretch to a designated position, and finally resetting and starting an automatic mode.
(2) And a fork empty alarm, which is a task of distributing the stock when the goods are fetched, wherein the stock position is in stock in a database, but the stock position does not have goods in practice, so that the fork empty alarm of the stacker is caused. Then the problem needs to be solved by deleting the stock in WMS (warehouse management system), and the task of deleting the stock position in the task management interface of the vertical warehouse needs to be further performed by entering the task of deleting the stacker itself from the screen of the vertical warehouse to the stacker.
RGV (rail guided vehicle): typically outside the store, but not too far from the store. RGVs themselves correspond to a platform and have chains, one side abutting multiple entrances and exits to the vertical warehouse, and the other side abutting the conveyor lines on multiple production lines. The operation mode is that the left and right movement is carried out on the rail. The task of RGV (guided vehicle) comes from WCS (warehouse control system), and the WCS (warehouse control system) generates corresponding task according to the request and sends it to RGV (guided vehicle) to make RGV (guided vehicle) carry out goods receiving and delivering task.
Conveying line: the carrying vertical warehouse, RGVs (rail guided vehicles) and the production line play a role in conveying goods.
The conveyor line is generally provided with photoelectric sensing at the front and back to detect the position of the goods; and the RFID sensing equipment is arranged above the conveying line, so that the production information of goods can be obtained according to the read RFID information and stored for subsequent warehouse-out use during warehouse-in. The installation positions of the conveying lines are arranged according to the actual conditions of the site, and are generally two sides of the vertical warehouse or two ends of the vertical warehouse.
Instructions for each hardware: and (3) stacking machine: how much to advance, how much to retract, lifting and lowering the cargo bed, resetting, deleting tasks, initializing, manually or automatically, and the like.
Conveying line: the chain rotates forward and backward, resets, is manual or automatic, and the like.
In another aspect, the present invention provides a computer storage medium storing a computer program for electronic data exchange, wherein the computer program causes a computer to execute instructions of a monitoring device for a WCS warehouse control system.
In yet another aspect, the present invention provides a computer program product comprising a non-transitory computer readable storage medium storing a computer program operable to cause a computer to execute instructions of a monitoring device for a WCS warehouse control system.
The invention integrates the monitoring and control equipment into a whole module, so that people can know and control all the equipment of the whole vertical warehouse only by one computer without entering the vertical warehouse or needing to walk back and forth. The current equipment state can be checked in real time, and the operation time of the equipment software layer alarm can be shortened. The method has the advantages that the state information and the operation parameters of all equipment in the vertical warehouse can be checked in real time, the safety condition of personnel is increased, the frequency of personnel entering the vertical warehouse due to the equipment alarming needs to be solved, the accident occurrence probability of a factory is reduced, and the shutdown time of the equipment in the vertical warehouse is shortened.
