Description
Technical Field
The present invention relates to an automatic control technique, and more particularly to an automatic control technique having a plurality of production processes.
Background
At present, when a system with a plurality of production processes is automatically produced, each system independently runs and accesses respective database, so that the production data of the same product cannot be unified, and the uniformity of the data of the previous and subsequent processes cannot be judged, so that data errors, data misjudgment, data missing and the like are easily caused, the product percent of pass is inevitably reduced due to abnormal data, and the automatic control method of the system comprising a plurality of production processes in the prior art is not high in flexibility, and if a new process system is added or the original process system is deleted, the hardware connection and the software control of the system are greatly changed, and the operation is troublesome.
Disclosure of Invention
The invention provides an automatic production control method, aiming at solving the technical problems that production data of the existing automatic control method with a plurality of production processes are easy to be abnormal and the flexibility is not high.
In order to solve the technical problems, the invention adopts the technical scheme that: the automatic production control method is applied to an automatic production control system, the system comprises a management system, a database and at least n process systems, the management system is respectively connected with the database and all the process systems, and the database is respectively connected with the management system and all the process systems, and the method is characterized in that: if the j-th process system can generate a file j1 and/or a file j2 containing the information of the currently produced products in the process, the file j1 and the file j2 are unique files in the management system and each process system, wherein n is an integer greater than or equal to 2, j is an integer greater than or equal to 1, and j is less than or equal to n;
for the management system:
when j is 1:
when the management system detects that the j1 is generated in the jth process system, the management system generates a j1 file in the management system; when detecting that the file j1 is deleted in the jth process system, the management system deletes the file (j +1)2 in the management system;
when j is more than or equal to 2 and less than n:
when the management system detects that the j1 is generated in the jth process system, the management system generates a j1 file in the management system; when the management system detects that the file j2 is generated in the jth process system, the management system generates a file j2 in the management system and deletes the file (j-1)1 in the management system; when detecting that the file j1 is deleted in the jth process system, the management system deletes the file (j +1)2 in the management system;
when j ═ n:
when the management system detects that the file j2 is generated in the jth process system, the management system generates a file j2 in the management system and deletes the file (j-1)1 in the management system;
for the jth process system:
when j is 1:
if the j1 file does not exist in the jth process system, the jth process system acquires the information of the product to be produced from the database or the management system and starts to produce, and after the jth process system finishes the current production task of the product, the j1 file is generated in the jth process system; when the jth process system detects that the file (j +1)2 is generated in the management system, deleting the file j1 in the jth process system;
when j is more than or equal to 2 and less than n:
if the j1 and the j2 do not exist in the jth process system, the jth process system detects the file (j-1)1 in the management system and starts production according to the product information in the file (j-1)1, and after the jth process system finishes the current product production task, the file j1 and the file j2 are generated in the jth process system; when the j process system detects that the file j2 is deleted in the management system, the file j2 in the j process system is deleted; when the jth process system detects that the file (j +1)2 is generated in the management system, deleting the file j1 in the jth process system;
when j ═ n:
if the j2 does not exist in the jth process system, the jth process system detects the file (j-1)1 in the management system and starts production according to the product information in the file (j-1)1, and after the jth process system finishes the current product production task, the j2 is generated in the jth process system; when the jth process system detects that the file j2 is deleted from the management system, the file j2 in the jth process system is deleted.
As a further optimization, the file j1 and the file j2 are both stored separately using a specified path. In each system, the file j1 and the file j2 are stored separately by adopting a designated path, so that when the system searches the file j1 or the file j2, the files under the corresponding path are directly scanned, the pertinence is strong, the time for searching the files can be saved, and the processing speed of the system is improved.
As a further optimization, the product information contained in the file j1 and the file j2 adopts the calling path of the product data in the database. If the data of the product is directly stored in the file, when the data of the product is large, the time required by the system to generate the file is long, and further the control efficiency of the system is influenced, so that the calling path of the product data in the database is stored in the file, the file is small, the generation speed is high, and when the system needs to use the data, the corresponding data is obtained according to the calling path of the data.
As a further optimization, the file j2 does not contain anything. When the file j2 is only used for feeding back that the system of the current process has completed the corresponding task, the content of the generated file j2 is empty, and the speed of generating the file is further improved.
The beneficial effects are that: according to the invention, the systems interact through the files, in the production process, the information of the product sequentially passes through the production processes, and the production processes produce according to the information in the corresponding files, so that the data of the product and the corresponding product can be in one-to-one correspondence, abnormal conditions such as data errors, misjudgments, missing and the like can be avoided, and the qualification rate of the product is improved. Meanwhile, each system of the invention independently scans corresponding files to carry out mutual control, and when process systems are added or deleted, only the process systems in each process are required to be subjected to file processing setting according to the method, so that the operation is simple and convenient, and the flexibility is improved. The invention is particularly suitable for an automatic production system with a plurality of production processes.
