Abstract

The utility model provides a movement protection detection device of a medical bedside X-ray machine, and belongs to the technical field of medical equipment. The movement protection detection device comprises a single chip microcomputer, an exposure switch interface circuit, a movement control unit interface circuit, a ray control unit interface circuit and an image collection unit interface circuit, and is characterized in that an exposure switch is connected with a synchronous control device; when the synchronous control device operates, the synchronous control device sends a movement starting command to a movement control unit at first to enable the movement control unit to execute C-shaped arm sliding operation, meanwhile detects position information of movement feedback, and sends a command to the movement control unit when the synchronous control device reaches a designated position, and at the moment, the synchronous control device synchronously controls a ray control unit to achieve X-ray exposure and controls an image collection unit to achieve image collection until all images needed by three-dimensional imaging are finally completed. The movement protection detection device has the advantages that the high-speed single chip microcomputer and a high-speed optocoupler are adopted in design of the circuits, functions are powerful, interfaces are simple, the system response speed is high, and safe and stable operation of the device is guaranteed.

Description

A kind of movement protection checkout gear of Medical bedside X-ray production apparatus

Technical field

This utility model belongs to technical field of medical instruments.

Background technology

At present, in the Medical bedside X-ray production apparatus equipment in electron medical treatment field, be used for realizing that the method that the movement protection of Medical bedside X-ray production apparatus detects is mainly to adopt the solid mechanical structure to add the mode of piezoelectric transducer, under this mode, when external force collision, the external force contact pressure sensor produces the movement protection detection signal, reaches the protection effect; But shortcoming is: in process of production, pressure transducer need to be fully enclosed in the solid mechanical structure periphery, lays area larger, is difficult for installing; In use; because pressure transducer is to be enclosed on the solid mechanical structure, can not dodge action to the people or the object generation that are knocked, even played detection effect; but in fact people or object have been caused to certain injury, can not reach satisfied protection effect.

From current mechanical & electrical technology, develop, can design fully a kind of convenient produce can well protect again thrusted into or the device of object; At first, can adopt soft displacement technology in frame for movement, in knockout process, make detection architecture that certain effect of dodging is arranged; Secondly, detection signal can be used high accuracy, undersized sensor, to reduce the production installation difficulty.

Summary of the invention

The purpose of this utility model is: the movement protection checkout gear of mentioning in comprehensive background technology, use soft displacement technology on frame for movement, and produce the distortion resetting-mechanism formed by upper and lower two sheet devices plates; Use high accuracy, undersized infrared emission detecting sensor in Electrical Appliances Designing, to reduce the production installation difficulty, realize producing guard signal under the minimum injury.

This utility model solves the technical scheme that its technical problem adopts: this device is by single-chip microcomputer, the exposure switch interface circuit, the motion control unit interface circuit, ray control unit interface circuit, the image acquisition units interface circuit forms, it is characterized in that: exposure switch connects sync control device, when sync control device is worked, at first send motion actuated order to motion control unit, motion control unit is carried out C shape arm slide, detect the positional information of motor feedback simultaneously, send order to synchronous control unit while arriving assigned address, now, sync control device Synchronization Control ray control unit realizes that X ray exposure and image acquisition units realize image acquisition, until finally complete the required all images of three-dimensional imaging.

The beneficial effects of the utility model are: circuit design adopts high-speed microprocessor and high speed photo coupling, powerful, interface is simple, system response time is fast, the assurance device safe and stable operation.

The specific embodiment

With reference to accompanying drawing 1, this device main services is controlled in the Medical C-arm three-dimensional imaging.

With reference to accompanying drawing 2, Medical C-arm three-dimensional imaging sync control device, this device is comprised of single-chip microcomputer, exposure switch interface circuit, motion control unit interface circuit, ray control unit interface circuit, image acquisition units interface circuit.

With reference to accompanying drawing 3 and Fig. 4, the data-interface switch_in of single-chip microcomputer connects the exposure switch interface circuit, move_in is connected the motion control unit interface circuit with move_out, exp_out connects ray control unit interface circuit, and camera_out connects the image acquisition units interface circuit; Wherein switch_in, move_in are as input port, and move_out, exp_out, camera_out are delivery outlet; In whole device running, move_in is as movement position information arriving signal, the final uniformity of picture position that obtains is only by this signal deciding, in implementation process, the move_in signal to be connected to the INT0 mouth of single-chip microcomputer, utilize the tighten control real-time response ability of circuit of the interrupt function of single-chip microcomputer.

With reference to accompanying drawing 5, there are following two kinds during the operation of Medical C-arm three-dimensional imaging sync control device and control sequential, at first single-chip microcomputer detects exposure switch signal switch_in, when high level occurring, send high level to motion control unit by move_out, now, motion control unit is controlled C shape arm and is slided, produce high electricity at the move_in foot while arriving assigned address, single-chip microcomputer utilizes the high level signal of interrupt function real-time response move_in, in interrupt routine, output exp_out is high level, the control unit that makes to expose produces X ray, and to export camera_out be high level simultaneously, make image acquisition units carry out image acquisition, the burst length that the move_in signal produces is 20ms, quantity is determined by the user, and mean allocation is in the sliding scale of C shape arm, the user is interrupt run at any time in the device running, now still can obtain the image of some.

With reference to accompanying drawing 6, the user does not have interrupt run at device in running, but after at C shape arm, all gliding motilities finish, and during the amount of images sequential chart that obtained conforming to setting, the user can unclamp the exposure switch complete operation.
