brief introduction

OA(Office Automation) Office automation

OA Office automation （Office Automation, abbreviation OA）, It's the computer 、 Communication and other modern technologies are applied to the traditional office mode , And then form a new way of office . Office automation uses modern equipment and information technology , Instead of some of the traditional manual or repetitive business activities of office staff , Handle office affairs and business information with high quality and efficiency , Realize the efficient use of information resources , And then increase productivity 、 The purpose of auxiliary decision making , Maximize work efficiency and quality 、 Improve the working environment .

MES(Manufacturing Execution System) manufacturing execution system

manufacturing execution system (manufacturing execution system, abbreviation MES) Is the U.S. AMR The company in 90 Put forward in the early s , To strengthen MRP The execution function of the plan , hold MRP The plan is the same as the on-site control of workshop operation 【SFC:shop floor control】, Linked by the execution system . The field control here includes PLC Programmable controller 、 Data collector 、 Bar code 、 Various measuring and testing equipment 、 Manipulator, etc .MES The system is equipped with necessary interfaces , Establish cooperative relationship with manufacturers providing production site control facilities .

manufacturing execution system MES It can help enterprises realize production plan management 、 Production process control 、 Product quality management 、 Workshop inventory management 、 Project Kanban management, etc , Improve the manufacturing execution ability of enterprises .

The same thing

It's all workflow 【WorkFlow】 System , Most of them are websites 【Web】 Form release , Generally, they also provide WebAPI or WebService And other interfaces are used for client-side docking and interaction , It is the flow between production links or process nodes .

Difference

OA System

Mainly paperless office and workflow processing , It is mainly used for personnel and administrative attendance .

The main forms are leave application form 、 Travel application form 、 Reimbursement application form 、 Item transfer order, etc .

OA Sometimes the system needs to be connected with the inventory system ,ERP System, etc .

The main database tables are ：

① Workflow type enumeration table 【 such as ： Ask for leave 、 Dispatch 、 document received 、 Reimbursement, etc 】

② Business form configuration table 【 For example, leave form 、 Reimbursement form 、 Dispatch form, etc 】

Automatically transfer to the leader for approval, after Li Si's approval , Automatically go to the personnel confirmation link, and Wang Wu confirms that the process is automatically completed

MES System

It is mainly used for automatic circulation of manufacturing process routes and inventory management , As long as the automatic flow of the process route is the core .

Process route, such as OCV Voltage test , Assembly of components , Side seam welding , Heat and stand ,CMT welding , Welding of connecting piece 、 Cutting and marking . Basically, every work station 【Operation Production process 】 There is incoming bar code verification , Data collection of outbound production parameters .

MES The system is basically connected with the upper computer PC Software 、 Motion control software 、 Test equipment 、PLC Data interaction, etc .

The main database tables are ：

① Process route and process configuration

② Inventory and work order management

③ Station parameter collection and control , Such as collecting test voltage
