The lifting of falling unit progress lifting column.For intelligent elevated column in lifting process, ZigBee-network determines the position of blind-guiding stick
Position judges that the movement speed of blind person calculates the speed that lifting column is gone up and down with this by the mobile message of blind-guiding stick, guarantees that blind person is supporting
Lifting column can drop to concordant with ground completely before up to lifting column.ZigBee net after blind person is by lifting column, in lifting column
Network detects blind-guiding stick by lifting column, and aut sign is sent commands to certainly to signal processing apparatus by signal processing apparatus
Dynamic lifting device completes the rise order of lifting column, and blind-guiding stick will not be cut off immediately at this time contacts with ZigBee-network, guide
The embedded ZigBee chip of cane is connected to reading green light residual time length in the ZigBee-network of lifting column, is arrived according to GPS positioning
Blind person position information by voice alerting unit prompt blind person whether speed change.
When blind person reaches crossing, signal lamp is exactly green light, the miniature webcam in blind-guiding stick gets signal
The color of lamp, voice alerting unit prompt blind person to open the switch that control lifting column is gone up and down, the mode turned on the switch and institute above
State it is consistent, blind person the finger of typing fingerprint is put on fingerprint identification device and use more than minimal dynamics by
Pressure, when device starting, the ZigBee-network in lifting column is attached with the ZigBee chip in blind-guiding stick at this time, is led
ZigBee chip in blind man's stick reads the green light residual time length of signal lamp in the ZigBee-network of lifting column, if when green light residue
Length < 5s is not enough to cat people by crossing, then the voice alerting unit prompt of blind-guiding stick waits green light next time；If when green light
Length > 10s, the voice alerting unit prompt blind person in blind-guiding stick is by crossing, when blind person receives and waits green light next time,
Lifting column is still in raw raised configuration at this time, only when ZigBee-network monitors that the ZigBee chip in blind person's blind-guiding stick starts
When mobile, elevating function can be just realized.
Blind-guiding stick realizes wireless charging function, in which: during the entire process of blind person passes through crossing, in blind-guiding stick
Wireless charging device in wireless charging receiver and lifting column is at working condition, when blind person passes through crossing
Afterwards, the ZigBee-network in lifting column can disconnect automatically the connection with the ZigBee chip in blind-guiding stick at this time in blind-guiding stick in
Central Processing Unit can carry out the remaining capacity in detection blind-guiding stick automatically, can be mentioned by giving prompt unit if electricity < 20%
Show that blind person's battery dump energy is low, and by GPS chip cooperate central processing unit find safe waiting place be total to blind person into
The unlimited charging of row, whether, when electricity reaches 50%, how much voice alerting unit prompts electricity, decided in its sole discretion by blind person after progress
Charging.
