Abstract
The present invention provides a bidirectional all-angle control microcomputer measuring device and its method. In particular it provides an effective measure to measure angle for controlling automobile handwheel steering, and solves the difficult problem of bidirectional multi-turn composite angle measurement in the traditional measurement method. Said invention can precisely and quickly collect, store and display angle data and can implement various related microcomputer control treatments. Its sensor structure is simple, compatibility is good, manufacturing cost is low and its installation is convenient and reliable.
Description
The present invention relates to the microcomputer measuring equipment and the method for arbitrarily angled control corner of the two-way rotation of a kind of bearing circle or displacement, particularly motor vehicle steering wheel is controlled the microcomputer measuring equipment and the method for wheel steering angle.
The orientation angle of automobile is an automobile important dynamic data under steam.But because the corner of bearing circle belongs to the compound angle of two-way multi-turn number, therefore if adopt traditional angle detector, to run into two hang-ups: at first, traditional angular transducer is original according to sample mechanical analog quantity or corner generation elastic properties of materials distortion and mechanical analogue to be principle of work quantitatively, they are applicable to the measurement low-angle, if be used for the measurement of two-way wide-angle, then to be subjected to the elasticity coefficient and the endurance ratio restriction of material because of the mechanical analogue sampling quantity, the anglec of rotation is big more, mechanically deform coefficient cumulative errors are also big more, just are difficult to be competent at.Secondly, traditional angular transducer complex structure, the manufacturing cost height, the condition harshness of on motor vehicle, installing, so, even present luxury models do not give the detection and the demonstration of angle yet.
The objective of the invention is to provide the two-way rotation of a kind of bearing circle arbitrarily angled measurement mechanism and method that any number of turns control turns to.This invention can be gathered accurate, apace and be preserved the angles of display data, and makes various relevant system controlled by computer and handle.
The present invention is achieved in that its core content is made of full angle sensor and microsystem calculation procedure two parts.Anchor ear is installed the interior annulus of full angle sensor on the bearing circle operating rod, is close to the cylindrical cover that the full angle sensor is installed outside the bearing circle operating rod.With interior annulus (body sways) even distribution M magnet steel in 360 ° of scopes that bearing circle rotates, fixed cylindrical puts even distribution N adhesive switch in 360 °/M scope.The arrangement of magnet steel and adhesive switch with arrange double replacement mutually.When bearing circle rotated, microcomputor program was judged the direction of rotation according to each switch of space distribution by the magnet steel attracting process and is calculated the angle of rotation.
The calculating formula of angular resolution is:
Whenever bearing circle rotate 360 °/(during M * N),
Active wheel rotation (Lb/La) * [360 °/(M * N)].
Wherein La is the maximum angle of bearing circle one-directional rotation, and Lb is the maximum angle of wheel one-directional rotation.By calculating formula as can be known: magnet steel is counted M and switch, and to count N big more, and angular resolution is just high more.By adjusting the numerical value of M and N, just can obtain satisfied angular resolution.And the angle of La/Lb is bigger than more, adjusts just fast more.
Concrete structure of the present invention in conjunction with the embodiments and description of drawings as follows:
Fig. 1 is the synoptic diagram of a kind of concrete full angle sensor construction that proposes of the present invention.
Fig. 2 is the calculating program frame chart of a kind of concrete full angle sensor angle that proposes of the present invention.
As shown in Figure 1, the full angle sensor is by magnetic attracting switch [1], [2], [3], [4], and magnet steel [5], [6], interior garden ring [8] and outer garden are overlapped [9] and formed.[1], [2], [3], [4] four magnetic attracting switches are installed in the outer garden cover [9], outer garden cover [9] is installed on the vehicle steering holder, is not rotate with bearing circle.On the garden cover [8], interior garden cover [8] is fixing tightly to be enclosed within on the bearing circle operating rod [7] in magnet steel [5], [6] were installed in.When rotating, operating rod drives magnet steel [5], [6].The magnet steel position must be installed on the position that magnetic switch can respond during installation.The adhesive of adhesive switch is connected when magnet steel [5], [6] turn to the scope that the magnetic attracting switch can respond with operating rod [7].In the time of outside magnet steel forwards magnetic attracting switching response scope to, magnetic switch just disconnects.Computing machine is to connect about angle that number of times and the elder generation of adhesive switch [1] to [4] adhesive calculated rotation afterwards and judgement according to the adhesive of magnetic attracting switch to turn to.The process block scale that turns to about angle that calculating is rotated and judgement is provided by Fig. 2.
In Fig. 1, when M=2, N=4, whenever bearing circle rotates 360 °/(2 * 4)=45 °, the angular resolution of control wheel steering is: (Lb/La) * 45 °.
Above conclusion is suitable for the situation of bearing circle control displacement equally.For example, to the displacement detecting in the worm-drive system.This moment whenever bearing circle rotate 360 °/(during M * N),
Working body displacement (Lb/La) * [360 °/(M * N)].Wherein La is the maximum angle of bearing circle one-directional rotation, and Lb is the maximum length of working body monodisplacement.
The present invention not only is embodied in high angular resolution and integrates with on the one hand with Computer Processing, and sensor is simple in structure, easy installation and reliable, the back is installed motor vehicle steering system is reached the ideal effect that does not destroy substance and do not influence original shape.And, form the standard serialization of product easily because the adjustment of angular resolution and magnet steel number, the proportional relation of adhesive switch number make the compatibility of full angle sensor very strong.
