Background
In the existing process system of cigarette industry enterprises, a tobacco shred manufacturing workshop is generally provided with a premixing cabinet, a tobacco leaf storage cabinet, a tobacco shred mixing cabinet and a finished tobacco shred cabinet. The storage cabinets in each area can store different batches of materials with different brands, each storage cabinet has material information such as batch numbers, brands and the like, and simultaneously, the storage cabinet states such as cabinet empty, full, cabinet entering, cabinet exiting, cabinet entering weight, residual weight, cabinet entering and exiting time and the like are displayed. The use of grouping processing and fine processing technology makes the material type of the wire manufacturing line show diversified development trend. The complexity of the material and the brand is easy to cause the phenomenon of wrong brands in the production process, once the quality problem of wrong brands and serial numbers in the tobacco production process occurs, the loss is very huge, the use of the tobacco is degraded by a light person, and the whole batch of tobacco leaves can be scrapped by a heavy person, so that the design of a brand production safety guarantee system is very important.
In order to prevent errors, in the conventional production control, the state of the storage cabinet and the material information in the storage cabinet are usually checked manually, and after the checking is finished, various production operations are performed according to actual conditions. However, with the proposal of industrial 4.0 theory and the continuous development of cigarette industry, the requirements on the production speed and the automatic production of a production line are higher and higher, and the control method for manually judging whether the cigarette can be put in or taken out of the cabinet cannot meet the requirement of the concept of an intelligent factory.

The error-proof control method for the storage cabinet feeding of the cigarette factory analyzes and considers that 2 process accidents or errors possibly occur when the storage cabinet is fed are as follows: mixing smoke and repeatedly feeding.
The first is the feeding and mixing of tobacco in the storage cabinet, which means that another batch of tobacco (or cut tobacco) is loaded in the storage cabinet which is not emptied, and especially when the brands of the front and rear batches of materials are different, the whole cabinet of materials can be partially or completely scrapped.
The storage cabinet is repeatedly fed, namely, a batch of materials with the same cigarette brand are loaded into the storage cabinet which is filled with the materials, so that the materials in the storage cabinet are excessive, and equipment failure is caused. It is mostly caused by malfunction.
A cabinet feeding error-proof control method for a cigarette factory storage cabinet comprises the following steps:
step 1, when a task is not started, a production management system issues a production task, wherein the production task comprises a storage cabinet needing to be fed, namely SiloID, the error prevention control method firstly judges whether the state of the storage cabinet selected in the task, namely SiloITobStatus, is empty or not in a PLC control program, if the state of the selected storage cabinet is empty, namely SiloITobStatus is 1, a diagnosis result is given that the cabinet feeding and the cabinet selection are successful, and other tasks cannot select the cabinet again; if the cabinet state is not empty, namely SiloitobStatus < >1, the diagnosis result is given that the cabinet entering and the cabinet selecting are unsuccessful, and the task starting operation can be executed only after the cabinet entering and the cabinet selecting are successful;
and 2, after the task starts, converting the cabinet storage state into a partially loaded SiloiToState which is 2, converting the cabinet entry state of the cabinet storage into a currently entered SiloinOutStatus which is 4, and simultaneously transmitting the work order information to a cabinet storage task work order interface, wherein the PLC error-proof control program compares the brand BrandID in the production task with the brand BrandID in the cabinet storage work order interface in real time according to the cabinet entry state to prevent different brands of materials from being mixed together to cause heavy loss, and meanwhile, a cabinet entry Start time, a cabinet entry type TypeOfLoaded and a cabinet entry weight LoadedWeight are generated, and other tasks cannot select the cabinet in the process.
And 3, after the production task is finished, converting the storage cabinet state into a state of finishing the loading of SiloiTobStatus which is 3, generating a cabinet entering end time LoadingEndTime, and starting to count the storage time ResidenceTime, wherein the error-proof control program does not allow other cabinet entering tasks to select the cabinet.
