Power circuit, it is to other module for power supply of whole touch demonstration and input system;
The LED display circuit, it connects LED light;
The touch screen signal treatment circuit, it is handled the capacitance variations signal that sends from touch signal collection pcb board;
The safety glass screen, it is the touch keyboard operation medium of double orthopaedics touch screen;
Touch signal is gathered pcb board, and it receives touch signal, and this signal is transferred to the touch screen signal treatment circuit;
Interface circuit and relay, they constitute generation keyboard signal assembly, and the keyboard signal of generation is delivered on the fracture healing instrument host control panel.
This utility model uses the capacitance touch scheme, and button touches in high-intensity safety glass surface, carries out physical isolation with internal circuit, and the surface is difficult to scratch, and can overcome the shortcoming of above-mentioned PVC film keyboard.And can waterproof and dustproof.
Description of drawings
Fig. 1 is the structure chart of the double orthopaedics touch screen of this utility model.
The utility model is described in further detail below in conjunction with drawings and Examples.
The specific embodiment
Referring to Fig. 1, double orthopaedics touch screen mainly comprises MCU microcontroller, power circuit, LED display circuit, touch screen signal treatment circuit, high-strength armoured-glass screen, and touch signal is gathered PCB, interface circuit, relay.
The operation principle of double orthopaedics touch screen is:
After touch objects touches the lip-deep respective regions of safety glass, gathering the capacitance that produces on the PCB in touch screen signal changes, be sent to the touch screen signal treatment circuit, fault-tolerant (the button time too short (anti-shake) that touches, multikey touches etc. simultaneously), anti-interference (EMI, ESD etc.), filtering, the AD conversion, data encapsulation is handled, be transferred in the MCU microcontroller by spi bus, the MCU microcontroller carries out corresponding computing then, carry out the A road with the LED lamp, the B road, keyboard touches the effectiveness indication, and driving relay generation keyboard signal is sent into the folding healing instrument host control panel of boning.
The function of double orthopaedics touch screen each several part and composed as follows:
1, MCU microcontroller
The MCU microcontroller is that ATMega 32 little process chip are arranged, and is 8 AVR processors, mainly carries out the signal identification that the touch screen signal treatment circuit is sent here, and decoding is handled, computing, and output LED index signal drives relay and carries out the generation of keyboard data.
2, power circuit
Power circuit converts civil power 220VAC to the 5VDC power supply, and the power supply with to each module of double orthopaedics touch screen mainly is made of the AC-DC module.
3, LED display circuit
The LED display circuit is to connect 3 high-brightness LED lamps to indicate the A road, B road, and the effectiveness of touch keyboard.
4, touch screen signal treatment circuit
The touch screen signal treatment circuit is to finish with the chip of a customization and RC filter circuit, it gathers touch signal, and the capacitance variations signal that pcb board sends is discerned, fault-tolerant (button time too short (anti-shake), multikey touch recognition etc.) simultaneously, anti-interference (EMI, ESD etc.), filtering, the AD conversion, data encapsulation is handled.
5, high-strength armoured-glass screen,
High-strength armoured-glass screen is used for internal circuit is carried out physical isolation, prevents that the external touch thing from damaging internal circuit, also is the physical medium of capacitance touch keyboard, can improve touch signal effectiveness, sensitivity, have simultaneously dustproof, good waterproof effect.
6, touch signal is gathered pcb board
It is two-sided PCB that touch signal is gathered pcb board, make a plate with special drawing mode in zone to each signal that need discern, the upper strata is that Φ 12mm disc format is covered Copper Foil, the zone of lower floor's correspondence is blank, the place of 1mm distance covers netted Copper Foil outside the disk of upper strata, the same position of lower floor covers netted Copper Foil, so just form a capacitance structure, when the no touch thing, with the air is medium, capacitance is constant, when touch objects, changed the medium of this structure, thereby capacitance changes, copper cash (each touch unit is isometric as far as possible to the wiring of touch screen signal treatment circuit, and is tiny as far as possible) by special layout is transferred in the touch screen signal treatment circuit again.
