1 is a configuration diagram showing a rear risk detection device according to a preferred embodiment.

As referenced, the rear risk detection device 10 for the hearing impaired according to the present invention includes a sensor measuring device 20 mounted to the rear of the hearing impaired and an app 31 for receiving a signal from the sensor measuring device. It is composed of a smart phone (30).

The sensor measuring device 20 is composed of a body 21 miniaturized in the form of a box or plate with an accommodation space formed therein, and a fastening portion 27 formed on one surface of the body, to the back of a backpack or clothes for the hearing impaired. It is provided in a structure that is attached in the form of an accessory. The main body 21 may be provided in the form of a character, and may be made of rubber or soft plastic so as to be capable of bending to some extent. In addition, the fastening portion 27 is formed on a surface in contact with a backpack or clothes, and the measuring direction is reversed by various methods such as a fastening structure such as a pin, an adhesive structure having an adhesive surface, or a hook structure forming a ring. The position can be fixed so that it can be mounted. In addition, the sensor measurement device 20 may be formed in a plurality to individually measure various directions in the rear to cause a notification by the smartphone 30 to be generated.

In the receiving space of the main body 21, an ultrasonic sensor 22 composed of a transmitting unit and a receiving unit is mounted. The ultrasonic sensor 22 may transmit ultrasonic waves rearward from the transmitting unit, receive ultrasonic waves reflected by an object at the receiving unit, and measure a distance to the rear object through a time interval between transmission and reception. The ultrasonic sensor may set 1 to 10 m as a detection area.

In addition, the acoustic wave sensor 23 is mounted on one side of the accommodation space. The sound wave sensor collects the sound transmitted from the rear side and detects that it is above a certain level. For example, a certain decibel sound, such as a car horn sound, or a loud call from the rear is detected and transmitted.

The main body is provided with a power supply unit 24, a sensor communication unit 25, and a sensor control unit 26. The power supply unit 24 supplies power to each device installed in the main body, and can be formed as either a battery replacement type or a rechargeable type, and can be provided as an external type in addition to the main body to be connected to the main body to provide power. have. In addition, the sensor communication unit 25 is capable of Bluetooth communication, and transmits various measurement values wirelessly through a Bluetooth connection with a hearing-impaired smartphone equipped with a sensor measurement device. In addition, the sensor control unit 26 controls the signal transmission to each part, and prevents fire by cutting off the power supply when overheating or installs a lamp on the outside of the main body to perform a function of notifying the power charging state through the lamp emission color. can do.

Next, the smart phone 30 is a smart phone installed by downloading an information providing app from a server, and is connected to the sensor measuring device 20 via Bluetooth to receive the measured value.

The app 31 includes a reading unit 32 and a corresponding signal generating unit 33. The reading unit 32 analyzes the measurement value transmitted from the sensor measuring device 20 to read whether a dangerous signal is present. Here, the reading determines whether an object is approached according to a change in the ultrasonic measurement value or a dangerous signal through the intensity of the acoustic measurement value. In other words, the degree of change in the measured value is preliminarily dataized and stored, and the corresponding notification is made by determining where the change in the received measured value corresponds to the data. For example, if the measured value is within 1 m, a very dangerous notification is made, and if it is within 10 m, a relatively weak notification is made. For example, a notification signal may be formed for each distance of the rear object. In addition, it is possible to determine whether the rear object is approaching or away depending on the degree of change of the measured value and select only the approaching object to generate a notification signal.

In addition, the corresponding signal generation unit 33 is a part that generates a corresponding signal according to the read result. As described above, when an emergency occurs, an emergency signal is generated, and when it is relatively less dangerous, only a warning signal may be generated.

When the corresponding signal is generated, the app 31 transmits it to the notification means of the smartphone 30 so that the user, the hearing impaired, recognizes the danger. As the notification means of the smart, vibration or light emission may be performed. The generated vibration can be classified as a warning in case of danger in case of continuous occurrence, so that a notification can be made.

In addition, as shown in Figure 2, the corresponding signal generated by the smart phone 30 can be transmitted to the smart glasses 40 to visually recognize the danger. That is, as illustrated, the light emitting unit 41 is formed on the inside of the smart glasses 40, that is, the rear of the glasses on which the eyeball is located, and when the corresponding signal is generated from the smart phone 30, the corresponding signal is transmitted to the smart glasses 40 connected by Bluetooth. The transmitted and transmitted smart glasses may emit the light emitting unit 41 to enable visual recognition.

Here, the light emitting unit 41 emits light in different colors depending on the degree of danger or proximity, so that the distance between the rear objects is recognized only by the color of the light emission, or by configuring a plurality of light emitting units, when the rear object is close to the entire light emitting unit Is emitted and the distance from the rear object increases, the number of emission of the light emitting unit is reduced, and information on the distance between the rear objects is provided by not only transmitting the presence or absence of an object to the rear, so that a suitable response to the situation can be achieved. have. The light emitting unit may be formed at various positions that can be easily recognized when wearing smart glasses.

3 is a block diagram of a method for detecting rear hazards according to the present invention.

As described with reference to the present invention, the method for detecting a rear hazard comprises a step of mounting a sensor measuring device, an ultrasonic distance measuring step, a sound measuring step, a measurement value transmitting step, a determining step, a corresponding signal generating step and a notification step.

The step of mounting the sensor measuring device is a step of attaching the sensor measuring device so as to be attached to a rear backpack or a rear clothes of the hearing impaired so that the measuring direction is directed toward the rear. In this step, the sensor measurement devices can be mounted on the left and right sides of the hearing impaired one by one, so that the measurement can be performed.

The ultrasonic distance measuring step is a step of emitting ultrasonic waves to the transmitter by the ultrasonic sensor of the sensor measuring device, receiving the ultrasonic waves reflected by the receiver, and measuring the distance by the time difference between transmission and reception.

The sound measurement step is a step of receiving sound waves transmitted from the rear through the sound wave sensor. The sound wave reception may be performed for a specific area or signal, such as a car horn sound.

The measurement value transmitting step is a step in which the sensor control unit receives the value measured by the ultrasonic sensor or the sound wave sensor and transmits it to the smartphone of the hearing impaired person through the sensor communication unit. This step can be continuously measured and the result can be continuously transmitted to a smartphone, or can be transmitted to a smartphone only when a specific signal is detected.

The determining step is a step of analyzing a measurement value through an app of a smartphone, and determining that the distance measurement value is within a set value or the sound wave measurement is greater than a set volume. In addition, it is possible to determine whether the rear object is approaching or distant by calculating the amount of change in the distance measurement value.

The corresponding signal generation step is a step of generating a corresponding signal in the corresponding signal generating unit when it is determined that the reading unit is a dangerous signal. That is, if the measured value is within the set range, a corresponding signal is generated, and when the rear object approaches the amount of change in the distance measured value, a corresponding signal is generated.

The notification step is a step of informing a hearing impaired person of a danger signal by generating vibration in a smartphone by a corresponding signal. The response signal generated by the response signal generation unit can be transmitted to the vibrating unit or vibrating unit and the light emitting unit of the smartphone to promptly inform the user about the danger through tactile sense and time to respond.

On the other hand, as described with reference to FIG. 4, the present invention can be determined by subdividing the distance measurement value for each set distance in the determination step. That is, it is possible to make a different determination for the distance measurement value for each distance from the sensor measurement device. For example, it is possible to differently step-by-step the signals provided at a long distance and a short distance, and determine that a signal corresponding thereto is generated.

In addition, in the step of generating the corresponding signal, the corresponding signal may be segmented and generated according to distance. That is, in addition to simply providing information that there is an object at the rear, it is possible to generate a corresponding subdivided signal to discriminate according to the interval of the object located at the rear.

In addition, a separation distance notification step may be further performed in the notification step. In the step of notifying the separation distance, the subdivided correspondence signal is transmitted to the smart glasses, and the smart glasses are spaced apart from the rear object by varying the number of light emission, light emission position, or light emission color according to the subdivided correspondence signal from a plurality of light emitting units installed at the rear. You can respond by providing information on the distance.
