Abstract
The invention provides a device for sensing the surrounding environment, and relates to the field of sensing technologies. The device aims to solve the problems that an existing visual impairment auxiliary instrument can not be applied to people who are disabled both in vision and hearing, muscle numbness or spasm of a user can occur if the existing visual impairment auxiliary instrument is used for a long time, and electrical brain simulation occurs. According to the device, N object detectors detect the distances and relative speeds of objects in different directions, a micro computer processing chip converts signals detected by the object detectors to voice control signals and sends the voice control signals to a moving-coil loudspeaker, the moving-coil loudspeaker gives out air billows of different frequencies and vibration rhythms, and a user judges the distance and speed of objects in different directions according to the frequencies and the vibration rhythms of the air billows. The user does not need to receive voice signals with ears, so that people who are disabled both in hearing and vision can also use the device, the air billows are different from mechanical vibration or currents, muscle numbness or spasm can not occur even the user uses the device for a long time, and pricking feeling certainly can not occur. The device is used for assisting the visual impaired people in sensing the surrounding environment.
Description
Technical field
The present invention relates to cognition technology.
Background technology
Common visual disorder supplementary instrument mainly feeds back user with sound, mechanical vibration and electricity irritation at present.Use sound feedback can not be suitable for the personage simultaneously with dysacousis.And general mechanical vibration mode pattern is simple, long-time being suitable for easily produces muscle numbness or spasm.Electrical stimulus patterns need to be chosen the neural intensive places such as tongue, and electric current can produce twinge simultaneously, and user is brought to misery.
Summary of the invention
The object of the invention is can not be suitable for the personage simultaneously with dysacousis in order to solve current visual disorder supplementary instrument, long-time use produces muscle numbness or spasm, and the problem of generation current stimulation, and a kind of device of perception surrounding is provided.
The device of a kind of perception surrounding of the present invention comprises N object detector 1, it is characterized in that: it also comprises micro computer process chip 2 and N coil-moving speaker 3, an a described N object detector 1 corresponding N coil-moving speaker 3 respectively, the detectable signal outfan of a described N object detector 1 connects the detectable signal input of micro computer process chip 2, a described N object detector 1 is for surveying distance and the relative velocity of different directions object, the N of described micro computer process chip 2 Sound control signal output part connects respectively the Sound control signal input part of N coil-moving speaker 3.
A described N object detector 1 is ultrasonic detector, radar detedtor or laser detector.
The frequency range of the blast that described coil-moving speaker 3 sends is 20Hz～20KHz.
The device of a kind of perception surrounding of the present invention is surveyed distance and the relative velocity of different directions object by N object detector 1, the signal that micro computer process chip 2 detects N object detector 1 converts Sound control signal to, and this Sound control signal is sent to N coil-moving speaker 3, N coil-moving speaker 3 sends the blast of different frequency and vibration rhythm, this blast acts on human body, and human body is judged distance and the speed of different directions object according to the frequency of blast and vibration rhythm.
The device of a kind of perception surrounding of the present invention in use, user does not need to receive acoustical signal with ear, therefore, the personage simultaneously with dysacousis also can use this device, and what this device acted on human body is blast, but not mechanical vibration or electric current, long-time use can not produce muscle numbness or spasm, does not more produce the sensation of twinge.
Brief description of the drawings
Fig. 1 is the electric connecting relation schematic diagram of the device of a kind of perception surrounding of the present invention;
The oscillogram of the blast that Fig. 2 produces for coil-moving speaker 3.
Detailed description of the invention
Detailed description of the invention one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, the device of a kind of perception surrounding described in present embodiment comprises N object detector 1, it is characterized in that: it also comprises micro computer process chip 2 and N coil-moving speaker 3, an a described N object detector 1 corresponding N coil-moving speaker 3 respectively, the detectable signal outfan of a described N object detector 1 connects the detectable signal input of micro computer process chip 2, a described N object detector 1 is for surveying distance and the relative velocity of different directions object, the N of described micro computer process chip 2 Sound control signal output part connects respectively the Sound control signal input part of N coil-moving speaker 3.
The device of a kind of perception surrounding described in present embodiment in use, N object detector 1 and N coil-moving speaker 3 are worn on as required to shirtfront, back and the left and right sides of user health, a described N object detector 1 is towards different, to guarantee to survey all around distance and the relative velocity of different directions, the sound basin of N coil-moving speaker 3 is towards the health of user.Judge surrounding for convenience of user, each object detector 1 and the coil-moving speaker 3 corresponding with it can be worn on to same position, for example, an object detector 1 and the coil-moving speaker 3 corresponding with it are worn to all left sides at user health, when blast is experienced in the left side of user health, user can be according to distance and the relative velocity of the frequency of this blast and vibration rhythm judgement left side object.Also N coil-moving speaker 3 can be combined into 30 centimetres wide, 20 centimetres high planes and be worn on user front inwardly, N object detector 1 is worn on to user front, and user can perceive distance and the relative velocity of front different azimuth object.
The signal that micro computer process chip 2 detects N object detector 1 converts Sound control signal to, as shown in Figure 2, this Sound control signal comprises frequency information and vibration cadence information, the frequency (pitches that different frequency is corresponding different) that different distances is corresponding different, different vibration rhythm corresponding to speed.Described Sound control signal is sent to corresponding coil-moving speaker 3 by micro computer process chip 2, described coil-moving speaker 3 is according to the frequency information in Sound control signal and vibration cadence information, send a section and have the blast of certain frequency according to certain hour interval, in certain hour, the hop count of blast is described vibration rhythm, and the scope of vibration rhythm is 30 times～200 beats/min.This blast acts on human body, and human body is judged distance and the speed of different directions object, perception surrounding intuitively according to the pitch of this blast and vibration rhythm.Wearing and using of device is very simple, does not need implant electrode, does not also need close contact skin, as long as hang over shirtfront, back or the left and right sides.User can be distinguished within the scope of 0.2 meter to 50 meters easily, the object of speed from 0 meter per second to 100 meter per seconds.And user does not need to receive acoustical signal with ear, the personage simultaneously with audition and visual disorder also can use this device, and what this device acted on human body is blast, but not mechanical vibration or electric current, long-time use can not produce muscle numbness or spasm, more can not produce the sensation of twinge.
