Accompanying drawing 1 is the wind-tunnel diffuser tension control system composition frame chart controlled based on PLC.
Embodiment
Further illustrate according to Figure of description citing below:
Embodiment 1
As shown in Figure 1, a kind of wind-tunnel diffuser tension control system controlled based on PLC, the PLC200 type controller unit 1 adopted possesses 224XP-N type CPU, ethernet communication module and 14 enters/10 go out I/O passage, digital quantity expansion module possesses 16 tunnel independence I/O passages, and digital output passage can change its output state by PLC.When input interface state changes, PLC is sampled to the input state of physics input interfaces all in the machine and expansion module successively, and then shows all channel statuses.This control system also comprises relay unit 2, direct supply and contactor auxiliary element unit 3, control panel unit 4 and displacement sensor unit 5, direct supply and contactor auxiliary element unit 3 are powered for native system, control panel unit 4 comprises control knob and status indicator lamp, PLC200 type controller unit 1 respectively with displacement sensor unit 5, control panel unit 4 connects, relay unit 2 is connected with each cover tensioning mechanism electric signal, each cover tensioning mechanism is provided with displacement sensor unit 5, and the requirement fully taking into account electromagnetism interference has carried out subregion isolation to the supply line of each unit.
After this control system powers on, mechanism's current operating state is fed back to the digital I/O input port on PLC200 type controller unit 1 by displacement sensor unit 5, PLC200 type controller unit 1 reads port status from digital I/O input port, current facility state can be intuitively shown, for the operation of operating personnel provides reference by mechanism status display lamp on control panel unit 4.Control panel unit 4 mainly comprises control knob and status indicator lamp, is the operating platform that operating personnel control each cover tensioning mechanism.When the control knob of operation control panel unit 4, the level of the digital I/O input port of PLC200 type controller unit 1 is changed, according to the logical relation preset in control program, PLC changes digital I/O output port level within the response time of tens μ s magnitudes, thus the coil closure state of electromagnetic contactor is controlled by pilot relay unit 2, realize the synchronous of Ge Tao mechanism or independently strain positioning function fast.After mechanism's execution steering order completes, the level that displacement sensor unit 5 feeds back to the digital I/O input end of PLC200 type controller unit 1 changes, PLC unit 1 scan round inquires mechanism's running status change, transfers to upper strata main control computer upgrade tensioning mechanism current state information via Ethernet interface.Driver Development adopts trapezoid figure language, is loaded in system kernel with modular form.When user needs change system logic, no longer need to redesign circuit, only need change the program after logic in PLC by downloaded at the scene, PLC will complete new updating logic programs automatically.
