Describe the 1 AMS system

1.1, AMS review

AMS (Assembly Management System assembly information management system) is to the bidding documents of automobile engine assembly line project control system requirements as the basis for the design and development of the object; control system mainly covers: assembly line body, carving machine, screw machine, clearance measurement, rotary torque measurement, seal leakage test, coating machine, machine, turning machine, valve lapping machine, washing machines and other equipment.

AMS can not only meet the various production requirements of control to solve the whole engine assembly process is specifically related to the domestic and international, and the latest automation and control technology and information control technology in combination, so that the system can meet the requirement of production assembly, flexible convenient strong expansion and. The AMS system on the left and the other control system interface such as: engine hot test line, plane, other parts of equipment.

1.2, the AMS network structure

According to the characteristics and functions of production data collection and information management, AMS is divided into AMS management, SCADA control layer, PLC layer and I/O layer control equipment, four layer structure of progressive layers, closely connected, a cascade structure. The bottom of the equipment is located in I/O layer of the whole system, responsible for the original signal acquisition and action execution; PLC control layer and device layer of I/O is closely connected with the equipment, I/O and terminal equipment acquisition signal and SCADA issued instruction combination, execution of the application of established; intermediate SCADA monitoring layer in the whole AMS, Rev. A connecting role, hand down and PLC control layer for data exchange, in order to realize monitoring the production process, on the other hand also up and management of AMS data exchange, AMS command execution assembly made of management, at the same time to the management of AMS to send real-time production data; top management in the whole system of AMS the whole assembly, responsible for data collection and statistics, analysis and management of the data.

See the following network topology diagram

The AMS system uses the high-speed Ethernet technology standard based on TCP/IP protocol, by category five twisted pair (or fiber) the information management of PC, SCADA monitor PC and PLC control together, constitute a production workshop lan. Real-time production data information through the network to achieve data sharing, 10/100Mbps high speed industrial Ethernet transmission technology makes data transmission time delay, delay greatly reduced, at the same time, real-time data transmission, synchronization has been greatly enhanced. The workshop area network, production and quality control engineers in the office PC can quickly learn to plant real-time production status and product quality information. The AMS system to the production of information, quality information and device information together, make the same production information possible, provide first-hand data for improving the production performance and improve the quality of products, equipment efficiency.

The AMS system uses the global fieldbus international standard ProFibus fieldbus master PLC, device controller (PLC), I/O (sensor) devices are connected together through the bus, made the master-slave control structure of PLC control system. Distributed fieldbus structure makes the field wiring and wiring work intensity greatly reduced, at the same time reduced cable has to a certain extent, reduce the line heating and interference. High speed ProFibus bus (transmission speed of up to 12Mbps) so that real-time data is greatly improved, the anti-jamming performance of ProFibus fieldbus is a strong guarantee the reliability of data transmission. ProFibus field bus has a strong fault diagnosis capability, when the equipment failure, can be the first time arrived at the scene, reducing equipment repair time, improve work performance.

Distributed I/O control mode of AMS system is dominated by industrial Ethernet production information management and monitoring system, ProFibus field bus as the dominant. Network between clear context, production data information through high speed network step by step, ensure the reliability and real-time information
