Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As Fig. 1, control system are controlled using half-closed loop control algorithm, the general control scheme that upper and lower machine jointly controls is carried out to edging machine.Wherein slave computer is PLC, mainly controls the sequentially-operating of shape expanding machine, it is ensured that punching course carrying out without any confusion.PLC is input into various switching signals, completes the output of the switching values such as controlled motor start and stop and magnet switching, and communicate by digital IO template and industrial control computer.Industrial Control Computer main task is the operational order and data that user is obtained by human-computer dialogue, and the order according to user completes corresponding industrial analysis and graph data shows and keeps corresponding data, and completes the communication with PLC, sends corresponding control command.
, including various buttons, switch and sensor signal etc., existing analog signal has data signal to output signal to control system input signal again including proportional pressure control valve, proportional reversing valve and variable pump etc., and in these signals.The input of analog quantity is mainly by pressure sensor, displacement transducer and is sent to host computer by analog input.Analog output is mainly host computer and controls proportional pressure control valve, proportional reversing valve and proportioning pump by analog output.The Stateful Inspection of digital quantity and control are mainly completed by various switches, oil strain jam signal, magnetic valve and digital IO plate.
Such as Fig. 2, control system triggers pattern gathered data using software, and the control system of equipment needs to detect pressurized cylinder pressure and pressurized cylinder oil pressure relief, the pressure and oil pressure relief of both sides cylinder, further need exist for detecting the displacement of both sides cylinder and liftout tank, and side cylinder spool position.5 pressure signals therein are gathered by the pressure sensor of each cylinder, and A/D change-over panels are delivered to by signal condition terminal board.Other 5 displacement signals are gathered by the displacement transducer of side cylinder and liftout tank, and A/D change-over panels are delivered to by signal condition terminal board.
