[Abstract]:At present, advanced manufacturing technology and Internet of things technology are developing rapidly. The traditional Job Shop workshop production management mode can no longer meet the rapid production needs of the workshop. Enterprises must improve the original production management mode through the relevant advanced technology. Under this background, this paper studies the relevant theories and key technologies of the Job Shop workshop mobile resource positioning perception system. The main work and research results of this paper include the following points: firstly, the demand analysis of Job Shop job shop location perception system is carried out, and the research object of location perception system is defined. on this basis, the architecture and physical topology of Job Shop job shop location perception system are established, and the data model of Job Shop job shop location perception system is constructed. Then, the real-time positioning method of material distribution car in Job Shop workshop is studied, and the two-stage positioning method of UHF RFID technology and ultrasonic technology is used to realize the real-time positioning of material distribution car. Firstly, the workshop stations are reasonably divided into several station level areas, and the UHF RFID technology is used to locate the position level logical area of the material distribution trolley. On this basis, the ultrasonic positioning technology is used to locate the position level logical area of the material distribution trolley. The experimental results show that the positioning method proposed in this paper can meet the positioning needs of the material distribution car in the Job Shop workshop. Secondly, the key technology of Job Shop job shop location perception system is studied, and the establishment of digital map of Job Shop job shop based on GIS technology is put forward to realize visual real-time monitoring of workshop production status, and the UML data model of Job Shop workshop manufacturing resources is constructed. On this basis, the UML data model is expressed by XML technology. Finally, through the analysis of the above research results, the prototype of Job Shop workshop positioning perception system is developed, the development environment and running environment of the system are clarified, and the database of positioning perception system is designed to complete the development of some functions of the positioning perception system.
