Abstract

The method includes the following steps: (a) using an analog/digital converter to convert the electronic signals into position data representative of where the magnet is disposed; (b) monitoring the difference of the position data in time and defining a movement amount representative of the position movement degree of the magnet in a time interval <DELTA>t; (c) if the movement amount is larger than a movement threshold THmove, converting a relative position into the pointing control signal, otherwise defining it as a stationary period; and (d) if the stationary period continues to thus form a stationary cycle Tstatic and the continuing time <DELTA> of the stationary cycle is larger than a resetting time, determining a floating origin from the position data in the stationary cycle Tstatic, wherein the relative position represents the difference between the position of the magnet and the floating origin.

Description

201042528 VI. Description of the Invention: [Technical Field] The present invention relates to a pointing method for a magnetic induction pointing device, in particular, an absolute origin of a magnetic sensing pointing device, and a magnetic sense The method of pointing the device to increase the yield, reduce the malfunction, improve the sensitivity, and extend the life of the device. &lt;Prior Art Ο The conventional magnetic induction pointing device refers to a pointing device that detects the position of a magnet. Since the magnetic-electric conversion is generated by the magnetic flux passing through and converted into an electronic signal output, the distance between the magnetic-electrical converter and the magnet can be determined by analyzing the strength of the electronic signal. The way in which the magnetoelectric converter senses the magnetic field is based on the principle that the power line is deflected in the magnetic field. When the electric field passes through the region where the magnetic field exists, the power line will be deflected in the direction perpendicular to the magnetic line to change the original electric field structure. Therefore, the general detection method is to circulate a fixed current on the magnetic-to-electrical converter, and then measure the current direction or the voltage difference in the vertical direction of the current, and the equivalent voltage is strong to indicate the magnet. The closer the magnetic_electrical conversion ^ is; otherwise, if the measuring voltage is weak, the farther the magnet is from the magneto-electrical converter. It can be seen from the above that when a pair of magnetic-electrical converters are distributed at both ends of the magnet and the voltage values of the two magneto-electrical converters are the same, they should represent the magnets at the moment 3 201042528 in the pair of magneto-electrical conversions. The middle position of the device. When the magnet is shifted to one of the pair of magneto-electric converters, the position of the center of the magnet offset can be derived from the voltage difference between the pair of magneto-electric converters. Therefore, the conventional two-dimensional pointing magnetic induction pointing device is shown in the second figure, which uses two pairs of magnetic '' electric converters to detect the position of the magnet on the X-axis and the γ-axis, including: two along the X-axis The magnetic-electrical converters 21, 22 arranged at the ends; and the magneto-electrical converters 23, 24 arranged along both ends of the Y-axis. And comparing the voltage difference between the magnetic-to-electrical converters 21, 22 at both ends of the X-axis through an X-axis differential amplifier 25; and comparing the magnetic-to-electrical converters at both ends of the γ-axis through a γ-axis differential amplifier 26 The voltage difference between 23 and 24. Thus, the output voltage of the X-axis differential amplifier 25 and the Y-axis differential amplifier 26 is converted into a magnet deviation - the X-axis and the Y of the origin 透过 through a type of ratio/digital conversion unit 31 and a formula conversion unit 32. The component on the axis. Wherein the above-mentioned origin 〇 is that the output value of the X-axis differential amplifier 25 is zero and the output value of the γ-axis differential amplifier 26 is also output to zero. It can be known from the above operation principle that if the conventional magnetic induction pointing device is to correctly convert the magnet movement 4 into a pointing transfer number, the following conditions must be met: 1) The magnetic-electrical dependence relationship of each magnetic-electrical converter must be the same; The direction of current applied to each pair of magneto-electric converters shall be symmetric with the direction of the magnetic dipole of the magnet; 3) each pair of magneto-electric converters shall be symmetrically equidistant; and most importantly, 4) When the magnet is applied to the magnet, the magnet tissue should be placed at the center of the two pairs of magneto-electric converters, that is, the origin. 201042528 In order to convert the position of the magnet, the center of the position of the two pairs of magneto-electric converters should be at the origin G. Thus, the x-axis differential amplifier 25 and the Y-axis differential amplifier 26 are input (4). The minus 'can' divide the X-axis component and the Y-axis component of the position where the thief is located. However, during the installation process, these magnetic-to-electrical converters may have some unpredictable insertion angles, or some deviations in positional arrangement, and the result is as shown in Fig. 1 The origin 〇χ is different from the original 'point Oy' of the Υ axis. It is clear that if the origin of the χ axis and γ pumping is not the job set by the secret, the signal output by the χ axis amplifier 25 and the 差 axis differential amplification H 26 cannot normally represent the position of the magnet. The weight of the. Ah, the pointing control signal representing the magnet deviating from the origin will continue to be sent without the magnet being stressed. The above abnormal recording can be used in the case of Tonglin, _, even in the normal state of the magnetic induction pointing device, after a period of use, the magnet will not return to the state without force. Go to the origin 〇 'Let the magnetic money point to the device and then be correctly. The purpose is that the magnetic induction pointing device mostly uses an outer side of the magnet to cover an elastic body to provide the spring recovery force after the force is applied, and the elastic structure of the elastic body will vary with the length of use, the number of times of knowing, The change in the temperature difference between the sun and the sun produces a lot of fatigue or structural fragility. Once the elastic body is fatigued or the structure is brittle, the most important contact force of the traditional fine device towel can no longer be provided, and the magnetic money pointing device can be directly sent out to represent the deviation from the origin Q. The error signal 'forcing the rhyme should point to the device's electronic product early termination of the product life 5 201042528 life. Therefore, in the pointing device disclosed in U.S. Patent No. 7,187,360, it is no longer necessary to determine whether the magnet moves by a single origin, but whether the magnet is defined by a circle of a constant radius. Eccentric movement. As shown in Figure 2, the non-detection area on the technical map ((10) This is the shed 11 field of the magnet origin, that is, as long as the magnetic_fine position is in the non-detection area, control The circuit will not send a pointing control signal to avoid various center position deviations during the assembly process to reduce the yield of the product. However, the above-mentioned US Patent No. 7,187, 360 only relies on the sensitivity of the product to reduce the risk of the product. Error, #The radius is used to set the range of the test area, and the product yield is improved. At the same time, the pointing device also loses a small range of pointing sensitivity. The radius of the social and slave is also only in the case of the force applied by the device. The generation of the pointing movement 峨' does not completely solve the real problem caused by the origin eccentricity. Taking the example of Fig. 3, if the magnet is in the unstressed condition, the actual center position is located at the mark ,', and the magnetic-f conversion n The position of the origin of the towel has an eccentric displacement B00'; when the magnet is forced to move to the west, the time (vector M0,) 'the magnetic sensing pointing device outputs - the starting point q Wrong direction That is, the movement to the northwest (vector M〇). It is obvious that the real direction (vector M0,) and the output direction (vector 刖) do not differ much when the moving distance is long; however, it is small When the range is moved, the actual movement and the output result are very different, so the traditional magnetic discrimination pointing device cannot apply the pointing input of the 201042528 to the small range. From the above, even if it is the above-mentioned _ listening mode, the sacrifice is small. The range-oriented movement sensitivity is to improve the product yield of the magnetic induction pointing device, but it only suppresses the occurrence of the error signal under the unapplied force. For serious direction determination problems, it can only be abandoned (refer to Figure 3). Why, most of the magnetic induction devices are only suitable for directional insensitive systems, avoiding the old magnetic sensation, pointing to the direction judgment error in the essence of the method. Let the original low power consumption and small volume advantage The magnetic induction pointing device loses its competitiveness and market advantage in the two-dimensional chain index because it gives up the direction and distance sensitivity. So how can Without sacrificing the sensitivity of the magnetic induction pointing device, the occurrence of malfunction is reduced and the problem of origin eccentricity is fundamentally solved, and the product 2 is reduced, the cost is extended, the service life of the device is extended, and the result of environmental protection and superior competitiveness is also achieved. The inventor is striving to achieve the goal. [Summary of the Invention] The main purpose of this month is to completely solve the problems caused by the traditional absolute origin eccentricity with the floating origin concept. Therefore, the present invention proposes a pointing method, which can be used for supervision. The position of the magnet changes with time to determine the position of the magnet when it is stationary, and the relative position of the magnet position relative to the floating origin is pointed when the position of the magnet is changed. Control signal output. Therefore, the pointing method of the present invention includes the following steps: (8) converting the magnetic-electrical turn, the electronic signal generated by the 'inductive magnet is the position of the magnet 7: 201042528; (b) monitoring the position data at the time The difference, and define a movement amount to represent the position of the above magnet in the -time interval Λί Degree of movement (6) if the amount of movement is greater than - the movement ugly value Tiw_ exchanges the bribe to the control signal, and conversely, the axis is the stationary period; and (the wheel is stationary: continues to occur and forms - the stationary period Tstatk, and the duration of the stationary period is greater than - When returning to zero time, the data from the position in the static ▲ period is converted into a miscellaneous ray, which is the difference between the position of the magnet and the floating origin. A further object of the present invention is to output the movement of the magnet over time to provide direction and distance sensitivity that cannot be achieved under conventional absolute coordinates, which comprises the following steps: (8) converting magnetic_electrical conversion_should-magnet generated The electronic signal is the position data representing the magnet; (b) monitoring the difference in time of the position data, and deducing a movement amount representing the positional relocation of the magnet in a time interval; and (6) if the amount of movement The greater than - the moving threshold THmove ' converts a displacement data to the above-mentioned pointing control signal, wherein the displacement data represents a displacement of the magnet in a time interval. In addition, the present invention also proposes an application of the above The pointing device of the pointing method includes: a housing having an open area, a sliding unit, a sensing unit, a control unit, and an analog/digital converter connecting the sensing unit and the miscellaneous unit. Each of the above units and converters are housed in the housing. At the same time, the control unit has a variable debt detector, a relative coordinate conversion 201042528 -=: 11 machine, - origin calculator, and - wheel person / wheel out component. The 'moon movement early 70 is the operation phase and the sleeve is attached to the elastic member outside the miscellaneous piece. In addition, the upper end of the operation member is the force end facing the opening area of the housing, and the lower end is the permanent magnet end orientation. The sensing unit. In this way, the control unit can know the position of the permanent magnet end through the magneto-electric signal of the sensing, and convert the relative position of the permanent magnet end riding-floating origin to the control signal output. . Unlike the conventional output with respect to the fine device of the absolute origin, the floating origin is derived from the position of the permanent magnet end in the stationary state, and the judgment of the stationary state is determined by the state machine according to the The amount of change in the permanent magnet end detected over time is known. In order to make the steps and structure of the present invention have a clearer image of the sun, the following is a detailed description of the best implementation. [Embodiment] As described above, the present invention is a floating origin concept, and the relative position between the conventional direct output magnet and the absolute origin is different. Therefore, the position of the magneto-electric converter can be sensed as long as it can sense the magnet. It can be, and is not limited to, the traditional X-axis and γ-axis symmetric arrangement as shown in Figure i. For T to monitor the difference in time of the position data Dg(t), a movement amount can be defined from the degree of change of the position information Dg(t) in the -time interval &amp;

Sh(t), for example, represents the moving distance of the above magnet in time (sh(1) three | Dg(t) - Dg_) | r), the component of the distance on the X axis _) three | Dg(t) - Dg (t-At)|x), or a component of the distance on the γ-axis (sh(t) e 9 201042528 |Dg(1)-Dg(t-At)|y) or a combination of the above amounts, and the like. With the different definition of the movement amount, it is judged whether the moving magnet threshold value THmwe is related to the movement of the magnet (4): 胄 the impurity amount is qing) three|Dg(t)-Dg(t-At)|r) ^ Sh (t〇)=THmove to time tG is shifted from the floating origin _radius_range; #the amount of movement is

Sh0E_&gt;Dg_|x,_)=ΤΗ_ can represent the above magnet from time (=-△__. The component of Na on the X axis is Li far; #% of movement %

= Pg(t)-Dg(t-At)|y » Sh(t〇)=THmove T The displacement of the displacement to time t〇 on the γ-axis is far from L2. If the movement amount S_TH_ is defined, the time interval is defined as a stationary period, that is, the Sh·in the work area_ shown in FIG. 4A, when the stationary period occurs continuously and a stationary period I* is formed, and The continuous maintenance time △T is greater than - 归科 _ 'Lee this part of the static lion inside the material fresh I_ point, gamma in the decoration _ _ _ turn, the relative position represents the location of the magnet and the The difference in floating origin points to the control signal. The horse is shown in the figure as the first embodiment of the present invention. When the Sh_TH_e (I zone) is defined as the stationary state ShOTiWn, the m zone), the magnet state is defined as the movement. (4). In the dynamic time, the relative position is converted into the above-mentioned pointing control signal wheel: the _, the point is the magnet position in the stationary period maintained by the stationary state, for example: the floating origin = 〈 Magnet A ctatip 201042528 The marking line S2 (black solid line) in Fig. 4A is a second embodiment of the present invention, and the pointing device applied has a push switch, when the push switch is pressed, the marking line B(t) In order to press (d〇wn) the potential signal, when the push switch is not pressed, the marked line B(t) is an unpressed potential signal. Therefore, when the user presses the push switch, the magnet may slightly change. In order to avoid misjudgment of the moving state and affect the floating origin operation in the stationary period, neither the moving state 41 nor the moving state is used. It is a static state of 4 〇, but a pressed state 42 representing the generation of a pressing action. The marking line S3 (grey solid line) in Fig. 4A is the third embodiment of the present invention, and the change of the amount of the moving amount is divided into three areas (I, n, and the change of the high speed threshold value _ _ m zone): When Shw^TH_e (I zone}, the iron state wire is in a stationary state 40; #THspeedgShw&gt;TH_e (II zone}, & the magnet state is defined as the mobility state and when Sh(t)&gt;THspeed( In the m region), the state of the magnet is defined as the high-speed moving state 43. Moreover, the conversion between the relative position 仏 and the pointing control signal sig conforms to a preset formula Sig=a*f(d^, where A is a unit scale, F is a function of the relative position ^. When the above magnet is judged to be in the state 41, Sig = A*F(10), Α = Αι; if it is in the high-speed moving state 43, the unit scale a is enlarged to a multiple of Αι &;, at this time % &gt; A * F (Dr) ' A = AH. So 'when the user moves the above-mentioned magnetic woven fabric at a faster speed', you can get the Congda multi-span pointing control call, the money user Quick view or a large number of moving window pointing actions. In addition to the high-speed threshold value ^叩^ as the relative position conversion scale of the Hungarian 201042528 break, The relative position can be directly converted by a value proportional to the amount of movement, such as Sig - A*K (Dr, Sh). That is, when the user moves the magnet at a faster speed, the self-aged magnifies the pointing New, to obtain a larger moving span' without the need to move speed up to the job - the degree of fitness has the function of adjusting the moving span. The marking line S4 (black dotted line) in Fig. 4B is the fourth embodiment of the present invention, The first two embodiments; ΐ; 岐 岐 ' 对于 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移 移_ability, 戦 发 发 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 It will be defined as the moving state 41, and the rest will be the stationary state 40. The pointing method of the present invention can be applied to the movement of the cursor 50 of the window, as shown by the movement of the magnet 27 shown in Fig. 5, the magnet 27 After the center position stays at the point ρ and exceeds the zero return time, the floating origin can be regarded as equivalent to the map. When the magnet 27 moves straight from the center position ρ point upward to the Q point, and then moves straight from the Q point to the right to the R point, the fifth embodiment of the present invention is exemplified, and the moving direction of the electric lining 5 〇 Equivalent to the displacement direction of the magnet relative to the #-origin (in this case, the P-point position), that is, the movement of the magnet from ρ to Q is applied to the movement of the computer cursor, that is, as shown in FIG. The upper linear movement mark H @ q _ is presented on the movement of the computer cursor, that is, the movement of the line is as shown in the figure to the upper right of the line 201042528 - the line moves the line L52. Obviously, in the fifth embodiment towel, the moving direction of the cursor actually displayed on the computer is not the same as the moving direction of the real magnet, especially the moving line L52 is a diagonally upward rightward movement, and the magnet is from the Q point to the R point. The line is obviously different to the right.

Therefore, in the sixth embodiment of the present invention, in addition to the movement of the computer cursor as shown in the above 5B, the movement trajectory of the magnet can also be realistically presented. That is to say, in the moving state, in addition to converting the relative position of the magnet relative to the D floating origin, the displacement data of the magnet from time (t〇_At2) to time ^ is also converted into a pointing. Controlling the signal, and the displacement data will represent the segmentation data of the moving track of the magnet, that is, the motion vector outputted at each time t〇 is not based on the floating origin, but in time (t0- The magnet position of At2) shall prevail. Thus, the moving magnet track in Fig. 5A can be truly converted into the reticle L53 and the reticle L54' shown in Fig. 5C, and the straight line moving from the Q point to the R point to the right magnet does not appear. A line L52 offset to the upper right as shown in Fig. 5B. In the sixth embodiment, the magnetic induction pointing device will subvert the application product of the old magnetic induction pointing device, and can be extended to various precise pointing systems, such as a graphic drawing system, a map navigation system, etc., to satisfy the general magnetic induction pointing device. Unreachable track movement function. When the pointing method of the present invention is implemented, the value of the moving threshold is not limited to a fixed value, and may also be changed according to the static state or the moving state to match the situation that may occur during actual operation. For example, when the magnet is in the moving state, the moving threshold 13 201042528 value THmove can be adjusted from the first preset value in the stationary state to the second preset value whose value is slightly lower, to provide a comparison in the moving state. High sensitivity; when the magnet moves to a relatively peripheral or specific area, the setting of the moving gate value is changed to match the magnetic-electrical dependence of the magnetic-electrical converter near the area, or the magnetic induction pointing The hardware condition of the device (for example: the elastic modulus of the elastomer, etc.). The pointing device of the present invention is a magnetic induction pointing device using the above pointing method. The seventh embodiment shown in FIG. 6A includes: a housing (housmg) 10; and is disposed in the housing 1 One sliding unit η, one sensing single unit 14 control unit 丨5, and an analog/digital converter connecting the sensing unit μ and the control unit 15 Η. The housing 10 has an open area 101 and a floor portion I2 disposed below the open area 1G1, and the sliding unit 11 is disposed on the support portion 12. The sliding unit is composed of an operating member (such as an area in the thick frame line shown in FIG. 8) and an elastic member 112 attached to the outer side of the operating member ln, and the upper end of the operating member m is The receiving end rib faces the opening area (8), and the lower end thereof has a permanent magnet end 11lb facing the sensing unit 14 and the elastic member 112 of the operating member 111 is disposed on the receiving portion. When the force receiving end 111a is subjected to the moving thrust, the elastic member 112 can support the operating member 111 and actuate 'and provide an elastic restoring force when the force path disappears to substantially return the air operating member m to the position before the force application. The point of the pointing device of the present invention is that even if the working piece is in the force road, the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The direction caused by eccentricity is misjudged. In order to measure the meaning of the U1, the sensing unit 14 is disposed below the sensing unit n, and includes at least two magnetic-electrical converters 14 142 disposed adjacent to the lower end of the permanent magnet end 11lb. . The magnetoelectric converters (4) and 142 can generate corresponding electronic signals of the magnitude of the magnetic flux passed, and convert the analog electronic signals into digital data through the analog/digital converter 151 for data analysis by the control unit 15. The control unit 15 includes: - a changer 152, a counter coordinate converter 153, a state machine 155, an origin calculator 156, and an input and output element 154. Wherein the change detector 152 detects the change of the digital data over time, and the relative coordinate converter I53 calculates the phase of the permanent magnet end (10) and a floating origin. _Change the small to determine the operating state of the operating member m. If it is in the mobile state, the control unit 15 outputs the pointing (four) signal of the phase miscellaneous_ by the input device 154; if it is in the stationary state, the origin calculator 156 re-establishes the time according to the stationary state. Define the floating origin. Therefore, the present invention is different from the conventional use of the absolute origin, and the origin calculator 156 will stop at any time. The navigation device U1 does not return to the original position before the force is applied after the force path disappears. The output pointing control signal does not appear in the case of origin eccentricity and misjudgment of direction. In addition, the push switch 16 can be placed under the sliding unit u to receive the trigger of the downward movement of the operating member m and electrically connected to the control unit 15 to provide a function other than the moving operation. Press the input selection. The pointing device of the present invention may further comprise: a trajectory calculator (not shown in the figure), and receiving the digital data for 4 nose out _ displacement data representing the displacement of the permanent magnet end mb in a time interval (displaeement And triggering the input/output component (9) to convert the displacement data to point to the control signal. When the sensing unit 14, the analog/digital converter 15 and the single control unit are controlled, at least one of them can be used on the same printed circuit board, or can be made in the same IC or single crystal. On the dome, the magnetic/electrical conversion n 14 142 in the sensing unit 可以 may be a (four) component (Hallde_t), or the Hall element may further include a plurality of amplifications and differential amplifications H, and the control unit 15 may also include : A microcontroller (MCU), or a central processing unit (CPU) and its firmware. The analog/digital converter 151 can be independently fabricated, can be compared with the control unit 15 on the same 1C or single-wafer, or can be analogized with the sensing unit 14 on the same ic or single wafer.
