Timer 306 is connected with the output terminal of X comparer 308 with Y comparer 310.When reference voltage generator 302 beginning output reference voltages, even central processing unit 208 timers 306 are started the clock.First voltage transitions is so far during second voltage thus when the magnitude of voltage of input timer 306, and timer 306 is promptly held the clock, and the value of institute computing time is relative digital coordinate values Cx or Cy.
Reference voltage generator 302 comprises constant current source I, comparison capacitor C 3, discharge switch S1 and charge switch S8.Discharge switch S1 and charge switch S8 are controlled by changeover control signal CtrlA1 and CtrlA2 respectively.Constant current source I is in order to provide a fixed current.Relatively the hot end of capacitor C 3 is connected with constant current source I through charge switch S8, the cold end ground connection of capacitor C 3 relatively, and the hot end that compares capacitor C 3 is in order to the output terminal of conduct with reference to voltage generator 302.When charge switch S8 conducting, decide power supply stream I to relatively capacitor C 3 chargings, this moment, relatively the voltage of the hot end of capacitor C 3 was linear increasing, this voltage is the reference voltage of reference voltage generator 302 outputs.The end of discharge switch S1 is connected with the hot end that compares capacitor C 3, other end ground connection, and when discharge switch S1 conducting, relatively capacitor C 3 promptly begins discharge.
When pick-up unit 200 entered sleep pattern, central processing unit 208 made Y grounding switch S4 conducting, and other switches all open circuit, and afterwards, central processing unit 208 also enters sleep pattern thereupon.When the user touched mouse touch control board 100,1 P1 of X layer version 102 contacted and conducting with 1 P2 of Y layer version 104, then woke capacitor C 1 up and began discharge through the contact point of P1 and P2 thus.When the voltage that wakes capacitor C 1 up during, P transistor npn npn Q1 conducting, and then make N transistor npn npn Q2 conducting less than a critical voltage value, at this moment, the wake-up signal W of wakeup unit 206 outputs by second level conversion to first level, to wake central processing unit 208 up.Then, central processing unit 208 makes and wakes switch S 7 conductings up, and P transistor npn npn Q1 then changes and opens circuit, and this moment, the wake-up signal W of wakeup unit 206 outputs transferred second level to.
Pick-up unit 200 needs to judge whether the user touches mouse touch control board 100, this moment, the step of central processing unit 208 control coordinate detecting units 202 was as follows: at first with X grounding switch S5, Y grounding switch S4 and Y power switch S3 conducting, if the voltage of the hot end D of X layer version 102 is zero; And if Y power switch S3 opened circuit, Y grounding switch S4, X grounding switch S5 and X power switch S6 conducting, when if the voltage of the hot end A of Y layer version 104 also is zero, expression X layer version 102 do not contact with Y layer version 104, that is the user does not touch mouse touch control board 100.
When pick-up unit 200 predicts the user and has touched mouse touch control board 100, need to detect user P1 and the indicated Building Y timestamp of P2 contact point in mouse touch control board 100, the coordinate detecting unit 202 in the central processing unit 208 control detection devices 200 and the controlled step of AD conversion unit 204 are as follows: at first, with discharge switch S1 conducting, make 3 discharges of comparison capacitor C.After comparing capacitor C 3 discharge offs, with Y grounding switch S4 and Y power switch S3 conducting.Because this moment, X layer version 102 and no current flow through, therefore can measure of voltage and the output of Y layer version 10 in P1, this output valve is Building Y mark voltage Vy.Then, discharge switch S1 is opened circuit, 8 conductings of constant current charge switch S, relatively switch S 2 conductings pick up counting with seasonal timer 306.When the output voltage of Y comparer 310 during by first voltage transitions to the second voltage, make timer 306 stop timing, this time interval is the Building Y scale value Cy of numeral.
When pick-up unit 200 predicts the user and has touched mouse touch control board 100, need to detect user P1 and the indicated Building X mark of P2 contact point in mouse touch control board 100 this moment, this moment, the control method of central processing unit 208 control coordinate detecting units 202 and AD conversion unit 204 was as follows: at first, with discharge switch S1 conducting, make 3 discharges of comparison capacitor C.After having put electricity, with X grounding switch S5 and X power switch S6 conducting, this moment, Y layer version 104 and no current flow through, and therefore can measure voltage and the output of X layer version 102 in P2, and this output valve is Building X mark voltage Vx.Discharge switch S1 is opened circuit, charge switch S8 and relatively switch S 2 conductings pick up counting with seasonal timer 306, when the output voltage of X comparer 308 during by first voltage transitions to the second voltage, make timer 306 stop timing, this time interval is the Building X scale value of numeral.
Pick-up unit 200 also can check whether be connected appropriate with mouse touch control board 100.When the Building X scale value of measuring is a higher limit, expression Y layer version 104 may hinder for some reason or get loose and not be connected appropriate with pick-up unit 200.This higher limit is reference voltage generator 302 beginning output reference voltages, to the time of this reference voltage greater than direct voltage source Vcc.Because the positive input terminal of working as comparer is as being suspension joint, then owing to the characteristic of comparer, this positive input terminal is equivalent to have a direct current voltage source Vcc.Because the user can not touch the edge of mouse touch control board, therefore the Building X scale value of measuring can not be to be touched and produced by the user, so caused by the suspension joint of positive input terminal as higher limit for this reason.In like manner, when the coordinate values of measuring is a higher limit, expression X layer version 102 may hinder for some reason or get loose and not be connected appropriate with pick-up unit 200.
