In Addition To The Car To Heat Control System Architecture Design

Because of more frequent winter snows, the snow began to complete the low temperature under the snow and ice storms, resulting in unpredictable effects. A wide range of snow, ice and strong cool weather to the transport, energy supply, power transmission, agriculture and people living with serious impacts and losses, urban roads and highways serious road snow ice, driving of vehicles , likely to cause traffic accidents. Therefore, for the winter road conditions, designed with snow and ice than floating function deicing vehicle heating control system. Deicing fluid heating control system design mainly includes outlet temperature control, temperature, pressure, flow display and alarm. The system uses Panasonic FPΣSeries PLC controller, which will deal with relevant input and output signals to drive the electric valve and the burner to control the overall de-icing fluid outlet temperature. Instrument as a display device display information on the pipeline.Based on the actual de-icing fluid control performance, design and construction of the deicing fluid heating control system experiment platform for the future of the heating control of deicing fluid to provide experimental basis. In this paper, designs, focusing on the work carried out are: research and analysis of the de-icing fluid heating, the control system of each control volume, de-icing system test platform designed to draw the schematic, design control logic. Analysis to determine the amount charged by a programmable control system, select the PLC, the design I / O points, draw the I / O connection diagram and wiring diagram of the external instrument. The hardware selection and parameter identification, design the overall layout of the control cabinet and complete PLC, meters, switch wiring. Determine the system heater and reservoir filling, the executing agency (sensors, solenoid valves, etc.) the actual site layout, complete the overall design of the hardware connection. Programmable control ladder program writing, debugging of hardware online. Innovation of this paper is to set up their own de-icing fluid heating control experimental platform, the use of robust disturbance on the flow control algorithm, which regulate the local track has a good effect on the subsequent development of de-icing equipment heating system with reference effect.
