Each module routine introduction
Infrared electric switch obstacle avoidance module
Infrared electric switch is a part in obstacle avoidance module, is blind-guiding stick " eyes ".The superiority and inferiority of its performance can be very
The performance of the blind-guiding stick function is influenced in big degree.In order to preferably detect preceding object, we divide in the upper and lower ends of crutch
It not placed infrared electric switch, when pressing obstacle detection key, barriers to entry detection pattern.Infrared electric switch, which detects, to be made
When having barrier within 30 centimetres in front of user, low level is exported, after the control pin of single-chip microcontroller detects the low level, is carried out
Voice broadcast " there is obstacle in front ".In view of ambient enviroment is noisy, the case where user may not hear voice prompting, Wo Men
At crutch handle, be mounted with vibrating motor, when detecting barrier motor also can vibrating alert user front have obstacle.Ranging
Functional block diagram is as shown in Figure 2.
Electronic compass guide module
In order to help user that can preferably recognize direction, HMC5883L digital compass is used to know direction
Not.It is communicated between single-chip microcontroller and electronic compass by I2C bus, electronic guide functional block diagram is as shown in Figure 3.When direction is distinguished
After other key is pressed, voice broadcast " east ", " south ", " west ", " north ", " southeast ", " northeast ", " southwest ", " northwest " 8 can be passed through
A orientation.
Voice broadcast module
In order to realize the intelligence of crutch, voice module is indispensable.The functional block diagram of voice broadcast such as Fig. 4 institute
Show.Central controller carries out serial communication to ISD1700 by the SPI protocol of four control line SCLK, MOSI, MISO ,/SS.
Using ISD1700 as slave, operation can be completed by SPI protocol.Spi bus system is that a kind of synchronous serial peripheral hardware connects
Mouthful, it can be such that single-chip microcontroller is communicated in a serial fashion with peripheral equipment to exchange information.Interface signal MOSI (MISO) is
Refer to main device data output (input), inputs (output) from device data；SCLK is the clock signal generated by main device；/SS
It is the slave device enable signal controlled by main device.In design, voice module is for prompting front obstacle, to front
Direction is illustrated, jingle bell of sending a telegram here, ringing at every hour, alarm clock and time are broadcasted.
Clock display module
Clock module selects ds1302 clock chip.The module is capable of providing the letter such as current time, week, month and time
Breath, is arranged these information also by clock setting key, alarm clock can also be arranged by key.Clock module not only has the leap year
Compensation function, and can be with adjust automatically when the number of days in month was less than 31 days.Since ds1302 chip has reserve battery
Pin, so button cell is connected on the pin, so that clock chip still can work normally after external power-off.
Display module is shown using liquid crystal 12864.Display module is mainly used to regulating time, i.e., when clock module is walked
When there is deviation, can be by pre-set key come regulating time, while being also beneficial to the time of setting alarm clock, household
By doing the time of something to this come reminding blind to blind person's setting alarm clock, is conducive to people and more easily uses.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 secondary design uses SIM900A communication module, realizes
The emergency of one key and the i.e. bidirectional call function that receives calls.It needs that the phonecard for having telephone expenses is installed in module before use, inserts
After upper earphone and Mike, it can be made a phone call to designated number by control button, other side can converse after answering,
It offers convenience to user.The module is connected by serial ports TXD, RXD with microcontroller serial port, realizes that a key is made a phone call and answered
Telephony feature.The entire block diagram of gsm communication module is as shown in Figure 6.
Locating module
In order to help friend blind person more easily to go on a journey, GPS positioning function joined in crutch.When friend blind person is lost
When, can press allows GPS positioning key, and household can see the position where blind person on pc machine, then accuse position
Know user or takes back user.The module is connect by serial ports with single-chip microcontroller, after allowing to position by key pressing, GPS
Module starts to position, and is sent to single-chip microcontroller by serial ports through latitude and longitude information, then single-chip microcontroller communicates this information to again
SIM900A module sends latitude and longitude information to host computer using GPRS communication, and host computer passes through processing for latitude and longitude information generation
The position of table is shown on map.The entire block diagram of GPS positioning is as shown in Figure 7.
