Abstract
The invention discloses a kind of gamma-ray nodestructive inspection equipment intelligent control instrument, this controller is applicable to the control of gamma-rays nondestructiving inspecting equipment and similar devices.The present invention is made of micro terminal, miniature programmable logic controller (PLC), optical disc, direct current torque motor drive system, adopt micro terminal to realize man machine operation interface, miniature programmable logic controller (PLC) telecommunication realizes intelligent control, and the direct current torque motor type of drive realizes little, the little vibration of noise, all even good driveability of speed.Safety of the present invention, reliable, easy to use.
Description
Technical field
The invention belongs to the control device of a kind of nondestructive inspection machine or similar devices, be specifically related to the control device of a kind of industrial gamma-rays nondestructive inspection machine or similar devices.
Background technology
Present industrial gamma-rays nondestructive inspection machine both domestic and external or similar devices controller mainly contain following two types:
1. non-programmable controller
Non-programmable controller adopts mechanical button, relay, contactor, mechanical type location counter, external travel limit switch etc. to form mechanical break contact formula control system usually, is equipped with step motor drive unit commonly used again and realizes.More and the general big and very heavy shortcoming of volume that all exists of components and parts that this control mode is used, thereby controller complexity and the failure rate height realized, and be difficult for expansion or revise once design typification, so the practicality extreme difference, the controller that adopts this type of control mode at present is seldom.
2. controller able to programme
The present representational mode of controller able to programme is to adopt the programmable single chip computer system as main control unit, operation interface is generally keyboard matrix or the order number array that mechanical button is formed, motion parameter collecting shows and the collection of motion state shows the functional module that employing is commonly used, is equipped with the step motor drive unit again and realizes.This control mode is simple to operate, use very general in the practical application, but because control operation and state indication are separated, realize that in the control of reality intelligentized control effect extremely bothers, and because the more complicacy that has increased system of peripheral circuit has also increased the failure rate of system simultaneously.
Above-mentioned two kinds of controllers commonly used exist a lot of not enough, adopts common mechanical button or touch that button makes that the control desk area is big, mechanical button or touch that button control linkage cable short, that be correlated with in serviceable life is many, information feedback and prompt facility is poor, reliability and security is lower.
In addition, realize that reliable and stable driving also is the key component of nondestructiving inspecting equipment, the drive system that other defect-detecting equipment is commonly used mainly contains drive systems such as stepper motor or asynchronous machine.Practice shows that there is the bigger shortcoming of stall step-out, vibration and noise in the step motor drive mode; And the Induction Motor-Driven mode exists shortcomings such as speed is inhomogeneous, vibration, unsuitable long-term stall.
Summary of the invention
The object of the present invention is to provide and a kind ofly can guarantee the safe reliability of gamma-rays nondestructiving inspecting equipment, the convenience and the intelligentized gamma-ray nodestructive inspection equipment intelligent control instrument of operation.
Technical scheme of the present invention is: adopt micro terminal to realize man machine operation interface, be characterized in: described intelligent controller comprise the micro terminal that connects by communication cable and miniature programmable logic controller (PLC), with miniature programmable logic controller (PLC) by output interface direct current torque motor drive system that is connected and the optical disc that is connected by input interface; Setting of micro terminal receiving system and controlled variable also are transferred to miniature programmable logic controller (PLC), miniature programmable logic controller (PLC) is transferred to micro terminal to motion state simultaneously and shows by collection and the action of handling realization control output control direct current torque motor system to the optical disc external signal.Intelligent controller is connected by being electrically connected with mechanical drive, is installed on the gamma-rays nondestructiving inspecting equipment.
Effect of the present invention is: 1. adopt micro terminal to substitute mechanical key or mouse-keyboard, realize the power of man-machine interactions such as various control operations and the demonstration of realization information state; 2. adopt miniature programmable logic controller (PLC) to realize the acquisition process of parameter and state and the reliability that control output has improved system.3. parameter acquisition is accurately reliable, makes system have more intellectuality, safeguards simple.
Description of drawings
Fig. 1 is a theory diagram of the present invention.
Among the figure: 1. micro terminal 2. miniature programmable logic controller (PLC)s
3. direct current torque motor drive system 4. optical discs
Embodiment
As shown in Figure 1, gamma-rays nondestructiving inspecting equipment controller of the present invention is made of micro terminal 1, miniature programmable logic controller (PLC) 2, direct current torque motor drive system 3 and optical disc 4.Micro terminal 1 is connected with miniature programmable logic controller (PLC) 2 by communication cable, realizes the mutual and remote monitoring of movement instruction and motion state; The main control unit of miniature programmable logic controller (PLC) 2 is realized calculation process and state I/O; Direct current torque motor drive system 3 realizes sending the source and receives source movement; Optical disc 4 is realized the conversion of location parameter photosignal.The output interface of miniature programmable logic controller (PLC) 2 is connected with direct current torque motor drive system 3, and the input interface of miniature programmable logic controller (PLC) 2 is connected with optical disc 4, realizes the output of external signal collection and control signal.
During use, micro terminal 1 receiving system setting and controlled variable also are transferred to miniature programmable logic controller (PLC) 2, miniature programmable logic controller (PLC) 2 is by collection and the action of handling realization control output control direct current torque motor system 3 to external signal, simultaneously motion state is transferred to micro terminal 1 and shows, finish the function of once detecting a flaw by time shutter timing control system receipts source to the storage position then.
According to actual nondestructive examination performance requirement, determine control and send every functions such as source position, be equipped with corresponding peripheral driver functional unit again, be electrically connected with mechanical drive by system's storage position signal and be connected, the present invention is installed on the gamma-rays nondestructiving inspecting equipment, and through test, result of use is good.
