Automatic control system, vacuum furnace core processing

The automatic control system, have the effect of core processing vacuum furnace, specific include the following contents:
1) communicate with touch screen program. Through rs - 485 read from the touch screen operation command and parameter Settings, and translating data types used by vacuum furnace operation; The process parameters and the running state of return touch screen for each station.
2) logical handler. According to the collected signal logic, issued on the system and the control signals of running state for each station. Complete skip transportation, vacuum pump, vacuum switch of each valve, given heating, cooling fan, furnace, inflated, etc.
3) fault alarm function: according to the technological requirements, a vacuum furnace brazing furnace temperature display abnormal low (or overtemperature), thermocouple damaged or open circuit fault alarm functions, such as when there is abnormal or fault occurs, the fault alarm signal corresponding to the temperature of the point of failure and the touch screen display signal will appear flashing at the same time, to remind the operating personnel in a timely manner to adjust the brazing furnace temperature and to deal with failure.
