The operating principle of high speed freezer automatic door control system described in the utility model:
First, after high speed freezer automatic door control system powers on, power supply indicator 15 is lit, system initialization button on user's point touching screen 5, input password enters and initializes interface, high speed freezer automatic door control system will automatically perform the action of opening the door, door leaf touches after door open limit switch 9, automatically perform the action of closing the door, now programmable logic controller (PLC) 4 reads the umber of pulse of optical rotary encoder 2, and count, when door leaf touches pass door limit switch 10, door leaf stop motion, programmable logic controller (PLC) 4 carries out computing, and in initializing interface, demonstrate the distance of the walking of door leaf, it is gate-width.
After initialization procedure completes, return to main interface, input password enters operational factor interface is set, and according to actual field, requires needed function is set, and user can click as required corresponding function button and carry out opening and closing.Function comprises: flash lamp, security function, automatic door-closing, automatic door-closing event, the middling speed node that opens the door, the low speed node that opens the door, the middling speed node of closing the door, the low speed node of closing the door.High speed freezer automatic door control system acquiescence flash lamp, security function, automatic door-closing function are closed condition (OFF state is that function is closed).
The switch gate velocity node parameter of high speed freezer automatic door control system and flash lamp, security function, automatic door-closing function setting are returned to main interface after completing, input password enters into operation monitoring picture, and now door leaf can normally be worked.The course of work is as follows:
Press door open button 17, the door leaf action of opening the door, first carrying out high speed opens the door, arriving middling speed opens the door after node and carries out middling speed operation, arriving low speed opens the door and carries out low speed after node and open the door, in touching door open limit switch 9(or programmable logic controller (PLC) 4, the umber of pulse of high counter is reduced to zero) after, door leaf stops action.If arrange and opened automatic door-closing function in interface in operational factor, the umber of pulse of door leaf high counter in touching door open limit switch 9(or programmable logic controller (PLC) 4 is reduced to zero) stop after, in setting-up time, do not have door leaf closing motion to occur, door leaf carries out with high, normal, basic three speed the action of closing the door successively.If press door close button 18, door leaf equally can be at each velocity node with senior middle school's low cruise, and the umber of pulse that touches high counter in pass door limit switch 10(or programmable logic controller (PLC) 4 increases to maximum value from zero) afterwards, door leaf stops action.
In open and close door process, when user uses pullswitch 12 or presses the button contrary with original action, door leaf is carried out contrary action with low speed.When door leaf is at limit switch place or during switch gate counting position, user uses pullswitch 12, and door leaf will carry out switch gate action with senior middle school's low speed.
