Technical field
The present invention relates to a kind of displacement speed sensor that in Industry Control, tame electric control field, uses, and the mouse beacon of using the computer operation of this sensor, particularly a kind of sphere moves, does not need the displacement speed sensor and the off-table type mouse of outer, stationary object of reference.
Background technology
At present in Industry Control, family's electric control, in the operation control of computing machine, employing velocity of displacement receptor is experienced the displacement of controlling part and the speed in tested article or the operation control, signal change with this displacement and speed is positioned at optical signal transmitter then, displacement that grid between the optical signal receiver moves and speed, make optical signal receiver receive interrupted light signal, these interrupted light signals are converted to electric signal, pass to microprocessor and handle judgement, obtain displacement and velocity information with this, article or the object that moves with this displacement and velocity information control actual needs makes it to move by this displacement and speed again.Or with the above-mentioned displacement that obtains and velocity information as detected signal, obtain the correlation displacement and the velocity information of mobile object.Displacement experienced by the velocity of displacement receptor here and speed generally is to get with the in-plane displancement and the translational speed of a movable part with respect to a stationary parts.
In the mouse of operation control computer, using more at present is half photoelectricity mechanical type mouse and optical mouse, and wireless mouse on this basis.
Wherein the velocity of displacement receptor of half photoelectricity mechanical type mouse be in the bottom cavity spin with and the roller bearing grid wheel that is mutually the right angle on every side constitute, in fact strict, also comprise static desktop or Mouse pad.Half photoelectricity mechanical type mouse is to pass through rolling mouse, (spin is above-mentioned movable part herein in static desktop rolling to drive spin, desktop is above-mentioned stationary parts), the rolling of the spin roller bearing grid wheel of being in charge of level and vertical both direction in the mouse bottom cavity that rubs again drives grid and takes turns rotation.The grid wheel is lattice-shaped.Near grid wheel grid both sides, a side is an infraluminescence pipe (being optical signal transmitter), and opposite side is infrared receiving unit (being optical signal receiver).Infrared receiving unit is a three terminal device, wherein comprises the first and second two infrared receiving tubes.Over against direction one contact roller is arranged with vertical roller bearing grid wheel angle in level, it makes spin to where all be pressed on all the time on two roller bearing grid wheels to rolling.During half photoelectricity mechanical type mouse operate as normal, mouse moving is converted to the rotation of level and vertical gate wheel different directions and rotating speed.When grid wheels rotated, the gear teeth of grid wheel periodically blocked infrared radiation that the infraluminescence pipe sends first pipe and the second pipe in the receiving unit, thereby first and second output terminal output electric pulse are to mouse inner control chip (being microprocessor).Because first and second liang of pipe homeotropic alignments in the infrared receiving unit, the mobile side of the part in the middle of the grid wheel gear teeth are clipped in infrared emission and receive is all above-below direction, and the angle of first and second receiving tubes and infrared transmitting tube is non-vanishing, so the electric pulse of the first and second pipe outputs has a phase differential.Mouse inner control chip is declared the rotation direction of knowing level or vertical gate wheel by this pulse phase difference, declare the velocity of rotation of knowing the grid wheel by the frequency of this pulse, the not open close data line of crossing interface circuit transmits the mouse mobile message to main frame, and main frame makes cursor and the same moved further of mouse on the screen by processing.
