Non-standard automation equipment refers to the customized, unique and non-market integrated automation system equipment which is assembled by unit equipment manufactured according to the unified industry standards and specifications promulgated by the state and developed, designed and manufactured according to customer needs. Different types of customers have different process requirements. The production of non-standard automation equipment is not as simple as that of general standard equipment, which can be completed according to specific regulations and processes. Non-standard equipment needs to be designed independently according to the specific use place, industry characteristics and purposes, and there is no specific reference model for the design of non-standard equipment. Non-standard equipment is not manufactured according to the unified industry standards and norms promulgated by the state, but is designed and manufactured according to the needs of its own use. And the appearance or performance is not in the national equipment product catalogue. Manufacturing drawings provided by design units and equipment processed in factories or construction sites are not finalized in China, and their usage is small. There are many kinds of non-standard equipment, including measurement, experimental test and performance verification, automation and mechatronics, hydraulic and transmission, special machine tools, project development, automatic assembly and so on.
Their production standards are different. After the non-standard equipment is approved, the engineering department will issue a manufacturing work order, and determine the source of funds, clear quantity, completion date and manufacturing unit. Generally speaking, arrangements can only be made after the drawings and documents are completed. For purchased parts with long import cycle and cast satin parts with long processing cycle, arrangements can be made in advance. Non-standard automation equipment pays more attention to modularity: because each user can customize products according to his own different needs. Non-standard automation equipment fully embodies its advantages in this respect, because there is only one module, so it can better play the performance of this module. The characteristic is simplicity. Non-standard automation equipment pays more attention to simple design. There is no need to use complicated equipment, and the function is user-defined. This is a relatively simple device.
