Description
Technical field
The utility model relates to a kind of Hearing Impaired's articles for use, specifically a kind of portable deaf person's dorsal part mobile object warning device.
Background technology
At present, more deaf person's auxiliary implement is arranged both at home and abroad, but also someone does not develop research to the special similar projects for deaf person's dorsal part mobile object warning device.Because the deaf person can't hear sound, therefore can't know whether the health rear sends a car, traffic trip inconvenience, also exist potential safety hazard.
The utility model content
Technical problem to be solved in the utility model is overcome deficiency of the prior art and a kind of simple in structure, easy to use, portable deaf person's dorsal part mobile object warning device that volume is small and exquisite is provided.
The technical scheme in the invention for solving the above technical problem is: this portable deaf person's dorsal part mobile object warning device, it is characterized in that: comprise detector and bracelet, be provided with the detector power supply in described detector, the ultrasonic detector module, detector master controller and wireless transmitter module, be provided with the bracelet power supply in bracelet, wireless receiving module, bracelet master controller and luminous shock module, described detector power supply respectively with the ultrasonic detector module, the detector master controller is connected with wireless transmitter module, the ultrasonic detector module is connected with the detector master controller, the detector master controller is connected with wireless transmitter module, wireless transmitter module and wireless receiving module wireless connections, wireless receiving module is connected with the bracelet master controller, the bracelet master controller is connected with luminous shock module, the bracelet power supply respectively with wireless receiving module, the bracelet master controller is connected with luminous shock module.
Luminous shock module described in the utility model comprises oscillator and pilot lamp, and pilot lamp is arranged on the bracelet surface.
Be provided with the fixation binding band on detector described in the utility model.
Ultrasonic detector module described in the utility model comprises ultrasonic transmitter and ultrasonic receiver, and both installations in the same horizontal line.
Bracelet power supply described in the utility model is chargeable polymer Li-ion battery.
The utility model compared with prior art has the following advantages: because the Hearing Impaired can't hear that the tucket on road is warned, so comparatively dangerous for their road trip.The utility model can be arranged on bicycle, electric motor car, motorcycle tail, distance between detection and front vehicle, pedestrian etc., when distance is less than safety value (1m), the alarm of bracelet vibration twinkling, thereby greatly improved the security of Hearing Impaired's trip, and when distance, the closer to the vibrations of, bracelet, strengthen, the pilot lamp flicker frequency is accelerated.The light prompting function can better embody effect when driving at night simultaneously.Considering that the less persistence for a long time of button cell specification drives oscillator and shaken, thus the utility model, adopt chargeable polymer Li-ion battery, not only improved the battery persistence, reduced the trifling step of changing battery simultaneously.
The accompanying drawing explanation
Fig. 1 is the utility model Bracelet structure schematic diagram.
Fig. 2 is the utility model panel detector structure schematic diagram.
Fig. 3 is the utility model schematic block circuit diagram.
Embodiment
Referring to Fig. 1 ~ Fig. 3, the utility model comprises detector 1 and bracelet 2, be provided with detector power supply 11, ultrasonic detector module 12, detector master controller 13 and wireless transmitter module 14 in described detector 1, ultrasonic detector module 12 comprises ultrasonic transmitter and ultrasonic receiver, and both installations in the same horizontal line.Be provided with fixation binding band 15 on detector 1.Be provided with bracelet power supply 21, wireless receiving module 22, bracelet master controller 23 and luminous shock module 24 in bracelet 2, luminous shock module 24 comprises oscillator 241 and pilot lamp 242, and pilot lamp 242 is arranged on bracelet 2 surfaces.Bracelet power supply 21 is chargeable polymer Li-ion battery.
Described detector power supply 11 is connected with ultrasonic detector module 12, detector master controller 13 and wireless transmitter module 14 respectively, ultrasonic detector module 12 is connected with detector master controller 13, detector master controller 13 is connected with wireless transmitter module 14, wireless transmitter module 14 and wireless receiving module 22 wireless connections, wireless receiving module 22 is connected with bracelet master controller 23, bracelet master controller 23 is connected with luminous shock module 24, and bracelet power supply 21 is connected with wireless receiving module 22, bracelet master controller 23 and luminous shock module 24 respectively.
The advantages such as described detector master controller 13 and bracelet master controller 23 adopt the STC11F04 single-chip microcomputer of macrocrystalline, and this single-chip microcomputer has volume little, and speed is fast.Wireless transmitter module 14 adopts the NRF24L01 radio transmitting and receiving chip with wireless receiving module 22.The NRF24L01 frequency of operation is 2.4GHz, data transmission rate be 250kbps to 2Mbps, its principal feature is that message transmission rate is high, transmitted data amount is large.Adopt the LED light emitting diode as pilot lamp 242, adopt DC micro-motor to produce as oscillator 241 and produce vibrations.Bracelet power supply 21 adopts chargeable polymer Li-ion battery; preferred battery model: AK551235P; capacity: 150mah; voltage: 3.7V; additives for overcharge protection electricity: 4.20V ± 0.05V; over electricity: 2.7V ± 0.1V, overcurrent protection: 3.0 ± 1.0A (2.7V ~ 4.25V).
When carrying out the measurement of distance, at first launch ultrasound wave and start the timer timing in detector master controller 13 simultaneously to the direction of dorsal part by ultrasonic transmitter, once will be reflected back after running into the barriers such as front vehicle in the way that ultrasound wave is propagated in air, after ultrasonic receiver is received reflection wave, will make it stop at once timing to the timer in detector master controller 13 to negative pulse.Like this, timer just can have been recorded accurately the ultrasound wave launching site and propagate time t(s used to coming and going between the dorsal part barrier).Because the aerial velocity of propagation of ultrasound wave at normal temperatures is approximately 340 m/s, so the barrier that dorsal part moves to the distance between the ultrasound wave launching site is: S=340 * t/2=170 * t.
Because in fact the timing of the timer in detector master controller 13 is exactly the counting to machine cycle T, and in the utility model, clock frequency fosc gets 12 MHz, design value N:
T＝12/fosc=1μs
t=N×T＝N×0.000001（s）
S＝170×N×T＝170×N/1000000（m）
Detector master controller 13 calculates distance according to above-mentioned formula, in the time that distance is less than the safe distance of setting, by wireless transmitter module 14 and wireless receiving module 22, triggers luminous shock module 24 and is shaken and luminous alarm.Relation between distance and bracelet vibration twinkling frequency can be set in addition in bracelet master controller 23.
The utility model is not limited to above-described embodiment, and all products identical or close with the utility model that draw under enlightenment of the present utility model, all belong to protection domain of the present utility model.
