The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
In Fig. 1 and Fig. 2, shown the assembly relation of crutch first segment shaft (7) with the second pole body (11).Crutch handgrip (4) vertically is installed in above the first segment shaft (7).Crutch handgrip (4) front portion is equipped with buzzer, reflective light-emitting caution lamp (2), ultrasonic sensor (3); Top is equipped with voice suggestion button, buzzing light warning button (1) and the built-in reception antenna of gps signal, and is connected communication with the internal electron system equipment respectively.Second and third, four pole bodies can shrink in the first segment shaft.
Locate mode with the first segment and second joint is an example, among Fig. 1, all there is a straight-line groove (5) crutch two pole body front portions, because the cooperating of fluted (5) and groove (16), crutch first segment (7) and second saves between (11) and can only can not rotate by circumference relative to sliding up and down.The locating hole (6) that the bottom of first segment shaft (7) has upper, middle and lower three row's spacings to equate, conplane three locating holes (6) are 120 ° of circle distribution, and it cooperates with three Spring Card buttons (10) that second joint (11) top mounts elastically.Adjust the crutch total length by the diverse location of card button (10) between the upper, middle and lower three registration holes (6) of first segment shaft (7) of regulating the second pole body (11).The below of second and third pole body also has a row to be the locating hole of 120 ° of circle distribution respectively, and matches with the Spring Card button of its next pole body simultaneously.
During use, the blind person can touch locating hole (6) corresponding in the groove at an easy rate, press the card button (10) in this locating hole (6), promote push rod (13), thereby spur spacing stay cord (12) on stud shaft (15) downwards, the card button that drives two other and stay cord (15) overcomes the indentation inwards of spring (9) thrust, and the location between cancellation card button (10) and locating hole (6) is packed up or pulled out crutch and moves.Unclamp card button (10), spring under thrust outwards push card button (10) up to from newly finding positioning hole corresponding (6) and location with it.
Fig. 3 is the overall structure block diagram of intelligent crutch.Whole electronic system equipment utilization two joint AA type 1.5V batteries or chargeable battery power supply, voltage is the 5V normal voltage by voltage conversion circuit with the 3V voltage transitions.After circuit system started, ultrasound wave was surveyed the barrier circuit and is sent and receive ultrasound wave continuously, has entered safe distance with after interior, the automatic sounding alarm of buzzer when detecting the place ahead barrier.Simultaneously, the GPS navigation system is also started working, and map datum leaves in the memory element, and the longitude and latitude coordinate data that the GPS-OEM plate receives is connected communication through level conversion with single-chip microcomputer by serial ports with time data, carries out the conversion of corresponding coordinate system and time system.The position coordinates of determining draws current coordinate place name exactly after tabling look-up with local map datum coupling.
During work, the blind person is leaning on the crutch walking, and ultrasonic sensor (3) constantly transmits and receives ultrasonic signal, in the time of in the barrier that detects the place ahead enters the alarm scope, and the buzzer sounding alarm on the crutch handgrip (4), the prompting blind person makes a response.When the blind person does not know current place position and time, press the voice suggestion button, current place name text and time data text are sent into and are carried out the synthetic output of text voice in the chipspeech.Place name that sounding loudspeaker voice broadcast is current and time.
Intelligent multifunctional guide crutch can be divided into five basic circuits:
(1) single-chip microcomputer operating circuit, the circuit board of this intelligent crutch can adopt the AT89C52 single-chip microcomputer as process chip, the application system of its formation, have low in energy consumption, volume is little, use flexible characteristic.The 26S Proteasome Structure and Function of system can carry out the personalization configuration according to demand, also can carry out the system peripheral expansion easily.This intelligent crutch requires the GPS-OEM plate to send data, and single-chip microcomputer receives, the storage data.Single-chip microcomputer and GPS-OEM plate are by serial communication, and system's baud rate is 4800bps, and the crystal oscillator that single-chip microcomputer uses is 11.059MHz, by these two numerical value configuration relevant register values.Initial configuration is imported by keyboard, and locating information is exported by the speech chip voice suggestion in conjunction with the place name of electronic chart.Simultaneously, single-chip microcomputer P1.0 mouth control ultrasonic transmit circuit produces the ultrasound wave of emission 40KHZ and starts timer internal, delivers to the P3.2 mouth by the needed interrupt request singal of edge transition generation single-chip microcomputer behind the time-delay 0.1ms and interrupts to trigger, and stops timing.Calculate the distance that ultrasound wave records, compare with the distance of setting to determine whether to send to report to the police and ask the P1.2 mouth, as shown in Figure 7.
