Abstract
The present invention relates to a method for detecting a rotation speed and a rotation direction of a rotating apparatus with the digital detection of a single sensor. In the method, a turnable which is connected with a rotation axis with a same axial center is provided on the rotating apparatus. Different directions of the circumference of the turnable are provided with a plurality of inducing pieces of a same sensor. The position angles formed by adjacent inducing pieces are not equal. The inducing pieces are arranged in the sequence of the magnitude of the position angle. When the turnable rotates, a sensor detects the pulse output generated by the inducing pieces. The pulse signal is obtained through a shaping circuit and is outputted to an arithmetic circuit and is connected to a display circuit. A time period S for rotating the turnable for a circle is the summation of a plurality of adjacent pulse interval lengths of a plurality of inducing piece compositions. The rotation speed of the turnable is digitally displayed. The arrival sequence of spacing interval of random adjacent pulse is obtained for determining that the rotation direction of the turnable is clockwise direction or counter-clockwise direction. The invention requires only one sensor for completing the digital detection to the rotation speed and rotation direction of the rotating apparatus. The installation position of the inducing piece of the sensor has no high requirement and the structure is simple. The cost for digital detection and the cost for installing the sensor are reduced.
Description
Technical field
The Digital Detecting Method that the present invention relates to the slewing rotating speed and turn to is especially with single-sensor Digital Detecting slewing rotating speed and the method that turns to.
Background technology
At present,, be to adopt on tested slewing, sensing chip to be installed, and produce pulse, obtain digital measured value through computing circuit, display circuit by sensor sensing to the rotating speed of slewing and the digital measurement that turns to.Normal conditions are the pulse signal computing velocitys that produce with a sensor, differentiate the steering direction of slewing with the signal of another one sensor generation.So the digital measurement task that two sensors could be finished the slewing rotating speed respectively and turn to must be installed respectively.Thereby detection cost and sensor installation cost have been increased.
Summary of the invention
The present invention proposes and a kind ofly the detection requirement that a sensor just can satisfy the slewing rotating speed and turn to promptly only is installed, reach and reduce the purpose that detects cost and installation cost with single-sensor Digital Detecting slewing rotating speed and the method that turns to.
Technical solution of the present invention:
The present invention is provided with the rotating disk that is connected with the rotating shaft coaxle heart on slewing, the different azimuth of rotating disk circumference is provided with a plurality of sensing chips of same sensor, does not wait at the position angle that adjacent sensing chip is formed, arrange by the position angle size sequence, during the rotating disk rotation, the pulse output that the sensor sensing chip produces obtains pulse signal through shaping circuit and exports computing circuit to, is connected to display circuit again.The time cycle S in one week of dial rotation is a plurality of sensing chips summations of a plurality of adjacent pulse interval time of constituting, and numeral shows the velocity of rotation of rotating disk; Get the order of arrival interval time of any adjacent pulse, judging dial rotation is clockwise direction or counter clockwise direction.
The sensing chip of described sensor has three at least, these three sensing chip installation sites on rotating disk constitute tactic little, in, big three position angles.
Technical scheme of the present invention is based on following algorithm:
(1) computing rule of rotating speed: the time cycle S in one week of dial rotation is three sensing chips summations of three adjacent pulse interval times constituting, and the account form of rotating speed is N=60/S;
(2) the judgement rule that turns to: get the order of three arrival interval times of any adjacent pulse, can judge dial rotation is clockwise direction or counter clockwise direction.
Beneficial effect of the present invention:
(1) the present invention only needs a sensor, can finish former two sensors to slewing rotating speed and the Digital Detecting that turns to;
(2) the present invention is less demanding to the installation site of sensor sensing sheet, simple in structure;
(3) the present invention has reduced the cost of Digital Detecting and the installation cost of sensor.

GreatlyWhen dial rotation one circle, sensor produces three different pulse signals with corresponding closely-spaced time of sensing chip setting angle, middle interval time and large-spacing time, this pulse signal, the shaping circuit in electric theory diagram as shown in Figure 2, computing circuit and finish the calculating of velocity of rotation are to the screen display digit testing result of display circuit.
And for example shown in Figure 3, get the order that arrives three interval times of any adjacent pulse, only carry out size comparison by computing circuit, can not judge the dial rotation direction and do not calculate concrete numerical value.The order that arrives as pulse is that T is little, among the T, T is big, then rotating disk is that clockwise direction is rotated.
Rotation direction is judged table
Another embodiment of the present invention:
Last embodiment can measure the dial rotation mean speed in one week, the even N five equilibrium of rotating disk can be pressed an embodiment three mutual unequal sensing chips of orientation angles are installed in each five equilibrium if improve the resolution of rotating speed, and installation requirement is:
