Each module routine introduction
Infrared electric switch avoidance module
Infrared electric switch is the part in avoidance module, is blind-guiding stick " eyes ".The quality of its performance can be at very great Cheng
The performance of this blind-guiding stick function is affected on degree.In order to preferably detect preceding object, we put respectively at the two ends up and down of crutch
Put infrared electric switch, when pressing obstacle detection button, barriers to entry detection pattern.Infrared electric switch detects user
When having barrier within 30 centimetres of front, output low level, after the control pin of single-chip microcomputer detects this low level, carry out voice
Report " there is obstacle in front ".Noisy in view of surrounding, user may not hear the situation of voice message, and we are at crutch
At handle, being mounted with vibrating motor, when barrier being detected, motor also can have obstacle in vibrating alert user front.Range measurement principle
Block diagram is as shown in Figure 2.
Electronic compass guide module
In order to help user can preferably identification direction, employ HMC5883L digital compass and direction be identified.Single
Being communicated by I2C bus between sheet machine and electronic compass, electronic guide theory diagram is as shown in Figure 3.When direction identification is pressed
After key is pressed, voice broadcast " eastern ", " southern ", " western ", " northern ", " southeast ", " northeast ", " southwestern ", " northwest " 8 sides can be passed through
Position.
Voice broadcast module
In order to realize the intellectuality of crutch, voice module is indispensable.The theory diagram of voice broadcast is as shown in Figure 4.In
Centre controller carries out serial communication by four control line SCLK, MOSI, MISO, the SPI protocol of/SS to ISD1700.Will
ISD1700 is as from machine, and operation can be completed by SPI protocol.Spi bus system is that a kind of synchronous serial peripheral hardware connects
Mouthful, it can make single-chip microcomputer and ancillary equipment communicate in a serial fashion to exchange information.Interface signal MOSI (MISO) is
Refer to main device data output (input), input (output) from device data；SCLK is the clock signal produced by main device；/SS
It is to be enabled signal by what main device controlled from device.In design, voice module is for pointing out preceding object thing, to front
Direction illustrates, jingle bell of sending a telegram here, ringing at every hour, alarm clock and time are reported.
Clock display module
Clock module selects ds1302 clock chip.This module can provide the information such as current time, week, month and time,
These information is set also by clock setting button, it is also possible to alarm clock is set by button.Clock module not only has leap year benefit
Repay function, and can also automatically adjust when the natural law in month was less than 31 days.Draw owing to ds1302 chip has reserve battery
Foot, so being connected to button cell on this pin so that after outside power-off, clock chip still can normally work.
Display module uses liquid crystal 12864 to show.Display module is mainly used to regulating time, i.e. walks when clock module
Time time deviation occurs, regulating time can be carried out by the button pre-set, be simultaneously also beneficial to arrange the time of alarm clock, household
Carrying out, by arranging alarm clock to blind person, the time that reminding blind does something to this, beneficially people more easily use.Clock
The entire block diagram of display module is as shown in Figure 5.
Gsm communication module
In order to enable blind person to call household under emergency situation, this has been designed with SIM900A communication module, it is achieved a key
Emergency and the i.e. bidirectional call function that receives calls.Need to install a phonecard having telephone expenses before using in module, plug ear
After machine and Mike, just can call to assigned number by controlling button, the other side just can converse after answering, and is made
User offers convenience.This module is connected with microcontroller serial port by serial ports TXD, RXD, it is achieved a key is made a phone call and received calls
Function.The entire block diagram of gsm communication module is as shown in Figure 6.
Locating module
In order to help friend blind person to go on a journey more easily, crutch adds GPS positioning function.When friend blind person gets lost,
Can press permission GPS and position button, household just can see the position at blind person place on pc machine, then be informed position and make
User or user is taken back.This module is connected with single-chip microcomputer by serial ports, after allowing location button to press, and GPS module
Starting location, be sent to single-chip microcomputer through latitude and longitude information by serial ports, then single-chip microcomputer communicates this information to SIM900A mould again
Block, utilizes GPRS communication that latitude and longitude information sends to host computer, and host computer is through processing position latitude and longitude information represented
Display is on map.The entire block diagram of GPS location is as shown in Figure 7.
