Virtual Instrument Based Control System for the Heating Box
In some industry and physical systems, work pieces should be baked for a long time before it is used. During heating, the temperature should change according to a line with a given slope, and the vacuum degree should be propriety, so the monitoring and control system is necessary. The monitoring system is used to monitor the vacuum, temperature in the heating system, it can also start the whole system and stop it when the situation is emergent. The control system make the heating system keep a programmed temperature. In this paper, a heating box is design, when the vacuum in the box is lost, the interlock system will turn off turbo pump power supply; at the same time, the control and monitoring systems are designed, the control system is made by PLC and the morning system is constructed by LabVIEW program, and the two systems communicated each other through TCP/IP.
