Based On Devicenet Elevator Control System

With the continuous development of information technique and Mankind society, as artificial intelligence wide application, the intelligence mansion has a fast development. The elevator control technique is a modern typical model and representative with technique of the surveillance and control technique. As a part of the intelligence mansion, the elevator control technique become importance part of it in many countries. In elevator supervise and control technique, because it has many control points for controlling object, and need the high accuracy of the control with supervise and control, we put forward the higher request to the elevator supervise and control technique. In elevator supervise and control technique, we should consider not only the safe movement of the equipments, but also the people's safety. Because of the control method of the some old style that main adoption in elevator handle style, therefore it still exists the current problem of the funds and the technique in the elevator reforms, which is a main aspect we need consider. At the same time, along with technical development in network, the network control also becomes an important aspect in the elevator supervise and control technique. Under such term, the technique of DeviceNet in industrial Fieldbus becomes our beneficial choice to the elevator supervise and control technique.In the industry control realm, as the technique of Fieldbus become the necessary way to realize the link between the devices of the process automation, manufacturing automate, mansion and transportation, etc. Now in the automation realm, we adopt generally three-layer network construction, namely devices layer, control layer and the information layer. As an importance part of CAN- BUS in the industrial Filedbus, DeviceNet is a total line in a kind of low cost communication. It links the industry equipments (such as, Limited switch, the light fax feels machine, valve set, motor starter, the process spreads to feel machine, a form code reads machine, changed rate machine, the front-panel display and the I/O of operation) to the network, so it dissolves the expensive cost on the hard wires. Connect directly with each other improved the communication of the equipments, and provided the very important equipments examine at the same time which is difficult to realize by hard I/ O connection. DeviceNet is a kind of simple network solution, it provides much provide goods the company of the same kind parts a cost for can compatibility at the same time, reducing the cost and time on the wires and installing industry automating equipments.Therefore, this thesis contact the elevator supervises and control technique to the technique of DeviceNet, aiming at the control point condition that elevator supervise and control complicated, control of equipments primarily is term that first floor equipments, with the guarantee the elevator the normal stability circulate next, put forward according to the DeviceNet supervises and control the system. At the same time, for the sake of better study to control in the DeviceNet to the elevator supervise and control system with the elevator that communication descend, we adopt the single machine aiming at the DeviceNet development method to the elevator supervise and control system to proceed the main hardware communication controls end the design of the electric circuit to the procedure in the software design. So we can realizes the elevator supervise and control through the hardware and the software.
