Embodiment
Below with reference to each embodiment shown in the drawings, describe the present invention.But these embodiments do not limit the present invention, the conversion in the structure that those of ordinary skill in the art makes according to these embodiments, method or function is all included in protection scope of the present invention.
As depicted in figs. 1 and 2, man-machine interface layer (Human Machine Interface, HMI) the 10th, the top layer of control system, is positioned at pipeline external.HMI layer 10 is interactive interfaces that control system offers operator, and by this interface, operator can carry out motion control and parameter setting to pipe detection equipment, obtains the various feedback informations of detection facility simultaneously.
Man-machine interface layer 10 is connected by wireless aps 11 with Communication Layer 20, wireless telecommunications have advantages of flexible, but consider that some engineering-environment (such as metal bending pipeline) is obvious to the shielding action of wireless signal, herein when design, for target control system has been reserved wired ethernet communication interface.Communication Layer and functional layer realize communication by RS485 bus 21, and for specific pipe detection equipment, Communication Layer main control device only has one, and functional layer master control borad 32 can be expanded by RS485 bus.
Functional layer need to comprise following several module:
(1) two-way stepper motor 331.As the drive unit of detection facility body, each road stepper motor drives 331 1 driving wheel rotations, by regulating motor speed, realizes the motion control of detection facility body.Stepper motor uses special-purpose motor driver to drive, and can regulate its rotating speed by changing pulse frequency.
(2) two-way direct current generator 341.For fork swings and cross bar slip provides power.Direct current generator drives by direct current generator driving plate, can regulate motor speed by PWM mode.
(3) dip sensor 35.By A/D modular converter access function layer master control borad, measure detection facility body superelevation angle, longitudinal upgrade angle and fork inclination angle.
