Specific embodiment
In order to make those skilled in the art more fully understand the present invention program, below in conjunction with attached in the embodiment of the present invention Figure, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only this hair Bright a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not having Every other embodiment obtained under the premise of creative work is made, shall fall within the protection scope of the present invention.
It should be noted that detection system provided by the invention is smoothness detection system, can be applied to rack Any field of track, such as foundry, using rack rail means of transportation, or manufactured using rack rail transmission Device.Also medical instruments field, such as suspention X-ray machine be can be applied to.
It is understood that the rack rail of suspention X-ray machine is to be arranged in the sky, it is to be understood that the detection system Also it can be applied to the rack rail positioned at ground.For example, to be located at ground fixed for vertical rail, and traverse rod can be transported on indulging rail Dynamic, the extending direction of the extending direction and traverse rod of indulging rail is vertical.Equipment under test can move on traverse rod again simultaneously.As long as by Measurement equipment can move the smoothness that can use detection system detection track in orbit under the drive of the motor.
In order to make those skilled in the art more fully understand scheme provided by the invention, it is applied to below with the detection system It is introduced for suspention X-ray machine.I.e. equipment under test is Suspenoing apparatus, and rack rail includes traverse rod and vertical rail.
System embodiment one:
Referring to Fig. 1 a, which is one schematic diagram of smoothness detection system embodiment provided by the invention.
As shown in Figure 1 b, which is suspention rack schematic diagram provided by the invention.
Traverse rod includes two traverse rods disposed in parallel, respectively X1 and X2.Vertical rail includes two vertical rails disposed in parallel, point It Wei not Y1 and Y2.
Wherein, Suspenoing apparatus 500 is arranged on two traverse rods X1 and X2, can move along two parallel directions of traverse rod. Two traverse rods can move again along two parallel directions of vertical rail simultaneously, and two vertical rails are fixed, and two traverse rods are It can with respect to two vertical rails movements.Therefore, during giving patient X-ray, Suspenoing apparatus may be implemented X-ray machine The movement of traverse rod direction, and may be implemented to move in vertical rail direction.
However, it is desirable to explanation, detection system provided by the invention can be the smoothness for detecting suspention rack, Suspenoing apparatus can change relative to the coordinate position of a rail in detection process, the coordinate position relative to another rail Constant, i.e., the corresponding traverse rod coordinate position of Suspenoing apparatus and vertical rail coordinate position will not change simultaneously.It can in detection process It is moved with controlling Suspenoing apparatus along traverse rod, keeps the coordinate position of the relatively vertical rail of Suspenoing apparatus constant, to detect traverse rod Smoothness.Alternatively, control Suspenoing apparatus is moved along vertical rail, keep Suspenoing apparatus constant relative to the coordinate position of traverse rod, from And detect the smoothness of vertical rail.
It is understood that corresponding two motors of suspention rack, one is vertical rail motor, another is traverse rod motor, institute Vertical rail motor is stated, for driving Suspenoing apparatus to move on the vertical rail of the suspention rack;The traverse rod motor, it is outstanding for driving Equipment is hung to move on the traverse rod of the suspention rack.
When detecting the smoothness of traverse rod, control Suspenoing apparatus is moved along traverse rod, acquires the output of traverse rod motor at this time Parameter.
When detecting the smoothness of vertical rail, control Suspenoing apparatus is moved along vertical rail, acquires the output of vertical rail motor at this time Parameter.
But in order to which testing result is more acurrate, when detecting the smoothness of vertical rail, acquisition Suspenoing apparatus is located at traverse rod not When with coordinate position, Suspenoing apparatus indulges the output parameter of rail motor along the multiple groups that vertical rail moves.For example, acquisition Suspenoing apparatus position In two different coordinate positions of traverse rod, respectively the first traverse rod coordinate position and the second traverse rod coordinate position work as Suspenoing apparatus When positioned at the first traverse rod coordinate position of traverse rod, first group of output ginseng of acquisition Suspenoing apparatus vertical rail motor when being moved along vertical rail Number;Suspenoing apparatus is allowed to be located at the second traverse rod coordinate position of traverse rod, acquisition Suspenoing apparatus vertical rail motor when moving along vertical rail again Second group of output parameter.If vertical rail smoothness is bad, corresponding in first group of output parameter and second group of output parameter The output parameter of the bad position of smoothness all can be abnormal.It is may insure in this way since motor exception itself or detection system are hard Error detection caused by part exception itself.
It, can be with the above is only to suspend the example for being located at two of traverse rod different coordinate positions and carrying out vertical rail smoothness detection in midair Understand, in order to more accurately detect the smoothness of vertical rail, Suspenoing apparatus can be set and be located at more different coordinate positions, For example, three different coordinate positions or four coordinate positions.
Similarly, when detecting the smoothness of traverse rod, when acquisition Suspenoing apparatus is located at the different coordinate positions of vertical rail, suspention is set The output parameter of the standby multiple groups traverse rod motor along traverse rod operation.Details are not described herein.
Suspention rack smoothness detection system provided in this embodiment, comprising: station acquisition device 100, motor output ginseng Number detection device 200, controller 300 and host computer 400;
The station acquisition device 100, for detecting coordinate position locating for equipment under test;
The motor output parameter detects device 200, for detecting the output parameter of motor;
It should be noted that the output parameter of the motor can be any one in following: electric current, torque and speed Degree;The motor is for driving the equipment under test to move on rack rail;
It should be noted that electric current, torque and speed can react the operation conditions of motor.It is preferably adopted in the present embodiment Use current of electric as the output parameter of motor.
When rack rail is smooth, the output electric current of motor is more steady, when rack rail is unsmooth, the output of motor Electric current is also unstable;Therefore, whether smooth the output electric current of motor can reflect rack rail.
In addition, the output torque of motor can also be detected other than the output electric current of motor, when rack rail is smooth When, the output torque of motor is also relatively more steady, and when rack rail is unsmooth, the output torque of motor is also unstable.Therefore, electric Whether the output torque of machine also can reflect rack rail smooth.Actually the output torque of motor can pass through the output of motor Electric current reflects.The output torque of motor is bigger, and corresponding output electric current is bigger;The output torque of motor is smaller, corresponding defeated Electric current is smaller out.Therefore, reflecting the whether smooth principle of rack rail using the output electric current of motor and output torque is one It causes.
Under normal circumstances, output torque can be calculated by exporting electric current, that is, when the mechanical structure of motor is fixed When, moment values are directly proportional to current value.Therefore, obtaining output torque can be obtained by output electric current, need first to obtain in this way Electric current must be exported, then obtains output torque.
In addition, the movement velocity of motor can also be detected other than the output electric current of detection motor and output torque.Work as machine When mounted track installation is smooth, the movement velocity of motor is substantially steady;When rack rail installation is unsmooth, the movement velocity of motor It can change greatly.Therefore, it can use the movement velocity of motor to judge whether rack rail is smooth.
The movement velocity detection of motor generally has following several method, and one is Hall sensor is increased, i.e. motor shaft is every One circle of rotation, Hall sensor then triggers once, and then calculates movement velocity, this kind of method needs to increase new component, may Bring the inconvenience of actual installation.Second is by the variation of stroke value in the unit time, calculating speed, this kind of method needs By stroke value, calculating speed value, real-time may not be high.The third is to select servo motor, and velocity amplitude can pass through servo Electric machine controller is directly read, it is generally the case that servo motor price is more expensive, and therefore, this kind of method cost may be higher.
The controller 300 is carried out for controlling the station acquisition device and motor output parameter detection device synchronization The acquisition of data, so that the coordinate position and the output parameter correspond;
The host computer 400, for receiving coordinate position output parameter corresponding with the coordinate position, according to described Coordinate position and the output parameter determine the smoothness of the rack rail.

For example, when the difference of the output parameter of motor and standard parameter is more than predetermined difference value range, it is determined that rack rail Road is unsmooth.
It should be noted that the acquisition of the effect of controller 300 mainly control data, and the calculation processing for data It is completed by host computer 400, host computer 400 has powerful data-handling capacity.The negative of controller 300 can be mitigated in this way Load.

Controller 300 receives position sampler by I/O interface and motor output parameter detects the data of device transmission, Received data can be filtered, filtered data are then sent to host computer by serial communication interface.
By taking equipment under test is Suspenoing apparatus as an example, join when vertical rail position sensor, traverse rod position sensor and motor export When the data of number detection device output are digital signal, controller 300 can be received directly.
When the data of vertical rail position sensor, traverse rod position sensor and the detection device output of motor output parameter are simulation When signal, AD converter is needed to be converted to digital signal, including two kinds of situations, one is controllers 300 itself to be integrated with AD converter, another kind are controllers 300 without AD converter, need individually to add AD converter.
Host computer 400 can receive the parameter of user setting, such as the weight etc. suspended in midair according to the setting of the model of suspention, because Different for the model of suspention, the standard parameter of corresponding motor is not also identical, it is to be understood that host computer 400 can be preparatory Save the standard parameter of the corresponding motor of suspention of multiple models.
It is understood that host computer 400 pre-saves the corresponding relationship of the coordinate position and standard parameter.It can be When rack rail is smooth, test of many times is first passed through in advance, the corresponding standard parameter of each coordinate position is acquired, for subsequent detection machine It is used when the smoothness of mounted track.It should be noted that the coordinate position can according to need to set, for example, in advance will Traverse rod is divided equally according to the first preset distance, obtains the traverse rod coordinate position of the equal partial node of each traverse rod;Obtain each traverse rod The corresponding standard parameter for being suspended in vertical rail motor when vertical rail moves of the traverse rod coordinate position of equal partial node;I.e. for each cross The equal partial node of rail controls vertical rail motor and moves on vertical rail, acquires the output electric current of motor.Save the coordinate position of traverse rod at this time The output electric current of (coordinate position of the current equal partial node of traverse rod) corresponding vertical rail motor.It should be noted that corresponding at this time The output electric current of motor can draw out curve, since rack rail is smooth, the curve of the output electric current of corresponding motor It is smoother.
It should be noted that the first preset distance can according to need to select, the numerical value of selection is smaller, the data of sampling More accurate, the smoothness finally judged is also more accurate.For example, the first preset distance can choose 5 centimetres, i.e., on traverse rod at interval of Once vertical rail motor moves corresponding output electric current on vertical rail for 5 centimetres of samplings.
Described above is the coordinate position of fixed traverse rod, samples the output electric current of vertical rail motor;It is same to fix vertical rail Coordinate position, acquire traverse rod motor output electric current when it is similar, details are not described herein.
Detection system provided by the invention, first pass through in advance test obtain rack rail it is smooth when coordinate position and standard parameter Corresponding relationship, during actually detected, by detection equipment under test motion process in motor output parameter, the electricity that will test The output parameter of machine standard parameter corresponding with the coordinate position is compared, and judges whether rack rail puts down according to comparison result It is sliding.The detection system can be realized automatically rack rail smoothness detection, compared with the existing technology in manual measurement rack The smoothness of track has the advantages that precision height and high-efficient.When the traverse rod of rack rail and unsmooth vertical rail installation, utilize The system can detecte out.
