Described power module 130 comprises overcurrent protection circuit, low electric weight feedback circuit and indicating circuit etc., can be built in conjunction with coding software by hardware circuit and realize.When directly powering, power supply changeover device starts overcurrent protection circuit and indicating circuit; automatic cut-off power during overtension; the indicating circuit pilot lamp becomes yellow warning by the green indication of normal operation; start low electric weight feedback circuit and indicating circuit when rechargeable battery powered; electric weight is crossed pilot lamp when low and is become red warning by the green indication of normal operation; rechargeable battery can be selected lithium ion battery (comprising lithium polymer battery), Ni-MH battery etc.
Described voice unit 140 comprises loudspeaker and related hardware control circuit thereof, can select according to the concrete function needs.
Described storage unit 150 refers to that sheet that power down is not lost deposits the unit of data outward, selects according to actual needs, and can be FLASH, SD CARD etc., after requiring PC and USB port 120 being connected, can carry out read-write operation to storage unit 150.
Described A/D converter 160 can according to the different chips of the concrete selection of the requirements such as sampling rate, can be the AD7874 of 4 Channel 12-Bits; Can be the AD7878 of 12 of dsp interfaces; Also can be the AD7888 of 12 of 8 passage low-power consumption; Can also be the AD7862 of two 12 of 4 passages, 12 the ADS7843 of high-speed transitions.
Described clock module 178,, select according to the particular hardware condition that microcontroller 170 has, can be the special clock chip, also peripheral active or passive crystal oscillator.
Described microcontroller 170, can be the single-chip microcomputer MSP430 series of industrial widespread use, can be current popular embedded scm ARM series, such as ARM7, ARM9, STM32 etc., also can be high speed, low-power consumption, jumbo FPGA(field programmable gate array) chip realizes the central processing module all functions, such as the Cyclone series of altera corp, the Spartan series of Xilinx company, the Pro ASIC series of Actel company etc.The scheme that other modules will adapt with it according to different microcontroller enforcement.
Described touch-screen 200, can select high-res, the high-speed transfer reaction, the high stability resistive touch screen, its major part is a resistance film screen that cooperates very much with display surface, this is a kind of laminated film of multilayer, it with one deck glass or duroplasts flat board as basic unit, the surface scribbles layer of transparent oxidized metal (transparent conductive resistance) conductive layer, and the above is stamped one deck outside surface cure process again, smooth anti-friction plastic layer, its inside surface also scribbles one deck coating, between them, there is the transparent isolating points of many tiny (less than 1/1000 inches) that two conductive layers is separated insulation.Please refer to Fig. 3, take 4 wire resistive touch screens as example, provided the interface circuit figure of touch-screen 200 with microcontroller 170, A/D converter 160.A/D converter 160 is take ADS7843 as example, and ADS7843 is a 12 bit A/D converters with the SPI interface that aim at touch screen design, and inside contains simulant electronic switch and successive comparison type AD converter.4 wire resistive touch screens are made of two transparent resistance films, and resistance is linear distribution at directions X and Y direction, and 4 line X_RIGHT, Y_TOP, X_LEFT, X_BOTTOM are connected to respectively X+, Y+, X-, the Y-mouth line of ADS7843.When touch-screen received the pressure of outer bound pair touch-screen, two conductive layers contacted in the touch point, and resistance changes.When the digital coordinate value of the Y-direction of will sampling, by Y+, Y-end is applied voltage, X+ is sent into the digital coordinate value that A/D converter obtains Y-direction; In like manner can get the digital coordinate value of directions X.And these conversions are finished to ADS7843 transmission order by the SPI agreement by microcontroller 170.With FPGA (Field Programmable Gate Array, field programmable gate array) is example, DCLK, CS, DIN, DOUT, BUSY, PENIRQ are connected to the GPIO(General Purpose Input of FPGA/Output) mouthful, by hardware description language definition SCLK, CS, MISO, MOSI function, DCLK is the external clock input; CS is chip selection signal, and is effectively low; DIN is the serial data input end; DOUT is the serial data output terminal; BUSY is busy signal; PENIRQ is for interrupting receiving pin.When screen was not stressed, the PENIRQ pin was high level, in case touched, this pin becomes low level by high level, sends interrupt request to FPGA.FPGA sends order by the SPI agreement that writes in advance to touch-screen, can read the directions X of current point and 12 bit digital coordinate figures of Y-direction.This value becomes linear approximate relationship with style of writing point position, so X and Y value that FPGA reads just can be described the position of style of writing point on screen.
Described touch-screen 200 can also be chosen piezoelectric type touch screen, and the piezoelectric type touch technology is between resistance-type and capacitive touch control techniques.The Touch Screen of piezoelectric transducer is equally supported multi-point touch with capacitance type touch control screen, and supports any object touch-control, only supports the material touch-control of class skin unlike capacitance plate.Like this, the piezoelectric type Touch Screen can have the multi-point touch sense of touch of capacitive screens simultaneously, has again the accurate of touch screens.The piezoelectric type touch-control more near the capacitive touch control characteristic, does not namely have the action of touch on power consumption characteristic, just do not produce power consumption, and resistance-type then constantly produces power consumption.On interface was supported, the piezoelectric type touch-control was supported serial ports, I2C and USB interface too.From process costs, the electric resistance touch-control processing procedure forwards piezoelectric type touch-control processing procedure to need to change apparatus for production line, and with capacitive ITO(Indium Tin Oxide, indium tin oxide) to compare with the processing procedure of mask combination, piezoelectric type touch-control processing procedure cost is between its 80%-90%.Can select as required the touch-screens such as resistance-type, condenser type, piezoelectric type.
The adjusting key button 220 and 230 that described touch-screen mark is drawn separates from touch-screen 200 both sides, adjusts page info and frame line alignment when making things convenient for the odd even page turning.
Embodiment:
