Specific embodiment
The present invention is described further below in conjunction with the accompanying drawings.
Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 are that a kind of structure of the tennis border judgment means shown in embodiment one is shown
Be intended to, as shown in figure 1, the tennis border judgment means include tennis bottom line patch 5, tennis bottom line patch 5 two ends be provided with
The perpendicular doubles sideline patch 3 of tennis bottom line patch 5, tennis bottom line patch 5 are connected with doubles sideline patch 3, the inner side of doubles sideline patch 3
It is provided with parallel with doubles sideline patch 3 and perpendicular with tennis bottom line patch 5 singles sideline patch 2, singles sideline patch 2 and net
Ball bottom line patch 5 connects, and the region between singles sideline patch 2 and doubles sideline patch 3 constitutes Alley areas 6, in tennis bottom line patch 5
Between be provided with center line markings 4, the middle setting of doubles sideline patch 3 has net 1;Described tennis border judgment means also include
The display device shown for computer that data are calculated and by result of calculation;Described tennis bottom line pastes 5 by 5
Rotating fields are constituted, and outermost layer is boundary line dyed layer 12, and the lower end of boundary line dyed layer 12 is sensor protection layer 13, sensor
The lower end of protective layer 13 is diaphragm pressure sensor layer 14, and the lower end of diaphragm pressure sensor layer 14 is diaphragm pressure sensor layer
Substrate layer 15, the lower end of diaphragm pressure sensor laminar substrate layer 15 is thermal insulation layer 16, described diaphragm pressure sensor laminar substrate
Layer 15 is provided with temperature sensor, and diaphragm pressure sensor layer 14 and temperature sensor are passed data back computer and carry out correlometer
Calculate;Described diaphragm pressure sensor layer 14 includes tested pressure conversion into elastically-deformable elastic sensing element, can be by
The signal condition that the elastic deformation of elastic sensing element is converted into the conversion element of electric signal output and the signal of telecommunication is nursed one's health
Circuit;The orlop of described elastic sensing element is tantalum pentoxide film 7, and the upper end of tantalum pentoxide film 7 is silicon dioxide
Film 11, the upper end of silicon dioxide film 11 is protecting film 10 for the upper end of resistive film 8, and the upper end of protecting film 10 is provided with golden film 9;
The tantalum pentoxide film 7 of elastic sensing element causes flexible sheet material to pass through five with 11 insulant of silicon dioxide film
Aoxidize two tantalum films 7 to adhere to well, while tantalum pentoxide film 7 is also the dielectric film of one layer of superior performance, silicon dioxide film 11
Insulating effect is played between change-over circuit and elastic sensing element substrate, and resistive film 8 is strain resistor film, will through photoetching process
Resistive film 8 is uniformly etched into several grizzly bar resistance, by the upper surface that design requirement is distributed in silicon dioxide film 11, when pressurized
Film resistor is deformed with flexible member, and the resistance of resistance accordingly changes, and the change of resistance is converted into voltage by circuit
Signal output, protecting film 10 mainly block the contact with air and sensor protection layer 13 of resistive film 8, golden film 9 and resistive film 8
Communicate, play a part of conductive electrode,
The operation principle of diaphragm pressure sensor layer 14 is resistance-strain type, and resistance change rate is relatively small, so change-over circuit
Favour stone full-bridge strain circuit is employed, this measuring circuit base friend sensitivity is high, and measurement range width, circuit structure are simple, essence
Degree is high, and the advantages of easily realize temperature-compensating, the presence of heat effect causes the resistance of film resistor with the change of ambient temperature
Change, while there is systematic error in operational process of craft, this measuring circuit for allowing for sensor has certain initial zero
Point tolerance and temperature error, the two errors have exceeded error criterion scope needs and have compensated, diaphragm pressure sensor layer 14
In conversion element measuring circuit using integral structure design " growth " on elastic sensing element surface, measuring circuit
Rapid dynamic response speed,
It is to connect one to be made by precision resistance material in road and bridge to carry out the simplest method of zero compensation to Wheatstone bridge
Filament winding resistance, can by the zero point of diaphragm pressure sensor layer 14 and function of temperature compensation control in the range of allowable error, while
Faint millivolt level signal of telecommunication diaphragm pressure sensor layer 14 exported by XTR106 integrated circuits is converted into being suitable for when big
The standard current signal of the 4-20mA of long-distance transmissions, and non-linear mistake compensate for by the linear compensation function of circuit
Difference, improves certainty of measurement,
Simultaneously using MAX1452 digital compensation circuit collection signal processing, temperature-compensating and one, by temperature sensor monitors ring
Border temperature, temperature value are converted to address pointer through A/D, by calling the zero point of this place indication and the compensation temperature system of full scale
Number, is modified to the temperature drift that diaphragm pressure sensor layer 14 exports zero point and full scale after D/A conversions, MAX1452
Digital compensation circuit is compensated to diaphragm pressure sensor layer 14, can be reduced the power consumption of diaphragm pressure sensor layer 14, be carried
High noise immunity, reliability and certainty of measurement;
When ball falls in tennis bottom line patch 5 or singles sideline patch 2, the diaphragm pressure of tennis bottom line patch 5 or singles sideline patch 2 is passed
Elastic sensing element in sensor layer 14 is experienced pressure or pressure and is deformed, and the resistance of resistive film 8 changes so that electricity
Resistance bridge exports a signal of telecommunication, and the signal of telecommunication nursed one's health into preferable signal output then, and computer receives right after signal
Signal is quickly calculated and shows result on the display device, and as singles, ball falls in singles sideline patch 2 or net
Ball bottom line patch 5 on now display device be shown as in boundary, when doubles ball fall tennis bottom line patch 5 or doubles sideline patch 3 on this
When display device be shown as in boundary;Total, the present invention has simple structure, with low cost, easy to use.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding can carry out multiple changes, modification, replacement to these embodiments without departing from the principles and spirit of the present invention
And modification, the scope of the present invention be defined by the appended.
