Description

Hazard prevention device and method {APPARATUS AND METHOD FOR PREVENTING DANGER}

The present invention relates to an apparatus and method for preventing a child from being at risk due to leaving a safe area or preventing a child from being at risk due to access to a hazardous area.

In the process of raising children at home, many safety accidents occur while parents take a moment to look away.

Even if a parent takes their eyes off a child for even a brief moment, the child can easily engage in risky behavior. However, it is difficult for parents to continuously and continuously check the current state of their child.

Currently, the real-time CCTV function that parents use is that unless the guardian is looking at the mobile phone connected to the CCTV, no special action can be taken even if an accident is about to happen to the child. In addition, since the existing CCTV system only performs a function of providing visual monitoring, there is a problem in that it cannot perform its function when the app is closed.

In Korea Patent Publication No. 2011267, when a baby approaches a dangerous object, the baby gets out of the vicinity of the dangerous object through the first warning, and when the baby stays around the dangerous object within a standard time despite the initial warning (e.g. A technique for preventing a baby staying in a dangerous object within a reference time from being injured by the visual warning and audible warning action is shown by no longer giving a visual warning or an audible warning.

Korean Patent Publication No. 2011267

An object of the present invention is to provide an apparatus and method for preventing an object from occurring in an accident in advance.

The device for preventing danger of the present invention includes: a sensing unit for detecting an event including departure or approach of an object to a set area; a generator configured to generate at least one of a function signal and an alarm signal when the event is detected, wherein the generator may display the function signal around the object or transmit the alarm signal to a preset terminal.

The risk prevention method of the present invention includes the steps of detecting the state of the child based on the setting area; Determining the departure or approach of the child to the setting area, and determining whether the child is in a dangerous situation; When it is determined that the situation is in danger, sending an alarm signal to the child's guardian terminal; may include.

According to the present invention, a departure or approach of an object to a set area is detected, and a predicted dangerous situation for an object such as a child may be estimated using the detection result.

The risk prevention apparatus and method of the present invention can automatically induce the object to get out of a dangerous situation at the same time as notifying a specific terminal of the danger of the object.

Considering a situation in which the object may be in danger due to the interaction of the object with the function signal leading to escape from the dangerous situation, a situation in which the dangerous situation of the object is tolerated or neglected in a specific situation may occur. The present invention can provide a method of not tolerating or neglecting a dangerous situation while preventing the occurrence of danger of an object due to interaction.

In order to prevent the danger of the object 90 such as a child, a pet, or an autonomous driving robot, the risk prevention device shown in FIG. 1 may include a sensing unit 110 and a generating unit 130 .

The sensing unit 110 may detect an event including departure or approach of the object 90 to the set area.

The generating unit 130 may generate at least one of a function signal and an alarm signal when an event is detected by the sensing unit 110 .

The generator 130 may display a function signal around the object 90 or transmit an alarm signal to a preset terminal 10 .

The alarm signal relates to a monitoring function, and the fact that a dangerous situation has occurred may be transmitted to the terminal 10 of a guardian such as a parent. The setting area z may be a safe area from various accidents or may include a dangerous area in which various accidents are predicted.

The 'dangerous situation' may include a first event ① in which the object 90 departs from a preset safe area. Alternatively, the 'dangerous situation' may include a second event ② in which the object 90 approaches a preset dangerous area.

The function signal may include an acoustic signal or a visual signal that induces the object 90 to escape from a dangerous situation.

For example, when the first event ① that the child wants to leave the safe area is sensed, the generating unit 130 may project an image of the child's favorite character in the safe area. In this case, the character image displayed in the safe area by the generator 130 may correspond to the function signal. The child can return to the safe area by following the image of the character displayed in the safe area.

For example, when the second event ② that the child approaches the danger area is detected, the generator 130 may output a warning sound in the danger area. In this case, the warning sound output to the danger area by the generator 130 may correspond to the function signal. The child can stop approaching the danger area and move away from the danger area, startled by the warning sound output from the danger area.

2 is a schematic diagram showing the sensing unit 110 of the present invention.

The sensing unit 110 is provided at a place spaced apart from the object 90 and has at least one of a camera sensor 111 , an infrared sensor 112 , an acoustic sensor 113 , and an ultrasonic sensor 114 having a setting area z as a detection range. may include.

The sensing unit 110 may detect a first event ① in which the object 90 departs from the set area z, or detect a second event ② in which the object 90 enters the set area.

When the first event ① or the second event ② is detected by the detection unit 110, the generating unit 130 generates and outputs a function signal to attract or expel the object 90, or generates an alarm signal to set the terminal ( 10) can be provided. The setting terminal 10 may include a mobile terminal 10 such as a smart phone used by a guardian or administrator capable of protecting and managing the object 90 . A guardian or manager who recognizes the alarm signal displayed on the setting terminal 10 may take protective measures for the object 90 .

Various communication modules capable of performing wired/wireless communication with the terminal 10 may be provided in the generator 130 .

3 is a schematic diagram showing the operation of the hazard prevention device of the present invention. 4 is a schematic diagram showing another operation of the hazard prevention device of the present invention. FIG. 3 may show a case in which an acoustic signal such as a warning sound for driving the object 90 away from a dangerous area is generated and output. FIG. 4 may show a case in which a visual signal including an image for guiding the object 90 away from the danger area is generated and output.

The sensing unit 110 may detect that the object 90 approaches the first position p1 spaced apart by a first set distance d1 from the set area z. In this case, the setting area z may be a hazardous area in which electric appliances, gas appliances, and the like exist.

As shown in (a) of FIG. 3 , the generating unit 130 may operate in the first mode for displaying a function signal for attracting the object 90 approaching the first position p1 away from the setting area z and the first position p1. have.

The generator 130 may initially operate only in the first mode while the second mode is excluded.

In the case of a hazardous area, the object 90 approaches the first position p1 after passing through the second position p2. Initially, the generating unit 130 may not operate in the second mode even when the approach of the object 90 to the second position p2 is detected by the sensing unit 110 . In other words, the generator 130 may not generate a function signal. The generator 130 may operate in the first mode only when the object 90 passes through the second position p2 and is detected at the first position p1 .

When the object 90 approaches the danger area in the order of the second position p2, the first position p1, initially not reacting at the second position p2 drives or attracts the object 90 away from the danger area. This is to increase the effect of the functional signal.

For example, when it is detected that the object 90 approaches the second position while the first mode is being performed, the generator 130 may stop the first mode and execute the second mode.

As an example, in the case of FIG. 3 , the first warning sound may be output between the dangerous area and the first location p1 by the generator 130 . In the case of FIG. 3 , the child may move in a direction away from the danger area and the first position p1 by being startled by the warning sound.

In the case of FIG. 4 , a visual signal r such as a setting image that the object 90 likes may be displayed on a floor surface of a position facing the danger area with the first position p1 interposed therebetween. In the case of FIG. 4 , the child may move in a direction away from the danger area and the first location p1 in pursuit of an image that the child prefers.

If the object 90 is moved away from the first position p1 by the first mode, the second mode may be executed such that the object 90 moves further away from the hazardous area.

For example, as shown in (b) of FIG. 3 , the sensing unit 110 may detect that the object 90 approaches the second position p2 that is farther than the first position p1 with respect to the setting area z. The distance d2 of the first location p2 with respect to the set area z may be greater than the first set distance d1.

The generating unit 130 may operate in the second mode for displaying a function signal for attracting the object 90 approaching the second position p2 away from the setting area z and the second position p2.

For example, in the case of FIG. 3 , a second warning sound may be output between the first position p1 and the second position p2 by the generator 130 .

In order to obtain both the effects of the first warning sound and the second warning sound using a single speaker, the generator 130 may adjust the intensity of the warning sound. As an example, the speaker outputting the sound signal may be installed between the dangerous area and the first position p1. Also, the generator 130 may set the second warning sound to have a greater intensity than the first warning sound. In other words, the second warning sound may be a louder sound than the first warning sound. According to this embodiment, an effect similar to the second warning sound output between the first position p1 and the second position p2 can be generated using a single speaker.

The object 90, which has been retracted from the first position p1 to the second position p2 by being chased by the first warning sound, may retreat beyond the second position p2 by being chased by the second warning sound again.

As shown in FIG. 4B , the visual signal r may be displayed at a position facing the first position p1 with the second position p2 interposed therebetween by the generator 130 .

3 (c) or 4 (c), in order to drive or attract the object 90 further away from the danger area, the third mode, the fourth mode, ... the nth mode (where n is 5) more than a natural number) can be added. The third mode, the fourth mode, and the like may include an operation mode in which an acoustic signal or a visual signal is displayed at a third location p3 that is farther from the dangerous area than the second location p2.

Meanwhile, the object 90 may attempt an interaction that intentionally induces an acoustic signal or a visual signal r generated and output by the generator 130 even though there is little interest in the danger area.

The generation of the acoustic signal or the visual signal r is made when the object 90 approaches the danger area to some extent. Accordingly, a situation in which the object 90 undesirably approaches the danger area may occur due to the interaction of the object 90 with respect to the acoustic signal or the visual signal r. Measures can be devised to reduce the incidence of risk from interactions.

An extreme comparative embodiment may be provided in which the functional signal is turned off to prevent intentional access to the hazardous area due to interaction.

However, according to the comparative embodiment, there is a problem in that the active action to retreat the object 90 approaching the danger area is stopped and the object 90 is left as it is.

In order to solve the problem caused by neglecting the object 90 , a method may be prepared to lure the object 90 away from the danger area using interaction.

For example, when the first mode is executed, the generating unit 130 stops the first mode after the lapse of the first set time even if the approach of the object 90 to the second position p2 is not detected, and performs the second mode. can run According to the present embodiment, it is possible to induce the object 90 enjoying the warning sound or setting image generated by the first mode to at least the second position p2.

In this case, the generator 130 may execute the second mode until it is detected that the object 90 moves away from the set area z and the second position p2 .

The object 90 played at the first position p1 may move toward the second position p2 with interest in the function signal displayed nearby disappears and the function signal newly displayed near the second position p2 .

The generator 130 may reduce the display intensity of the function signal generated in the second mode when the state in which the object 90 approaching the first position p1 is not detected at the second position p2 continues for a second set time. can

The generator 130 may restore the display intensity of the functional signal to its original state when the object 90 is detected at the second position in a state in which the display intensity of the functional signal is reduced.

The object 90 interacting with the function signal can learn the interaction that the function signal is displayed at the second position and must approach the second position so that the function signal is output with its original strength when the display strength or output size becomes small. can As a result, the object 90 approaching the first position is retracted to the second position.

According to the operation of the above generating unit 130, the object 90 learns the fact that the interaction normally occurs only when it approaches the first position and returns to the second position, and in order to repeat the interaction, The access may be retried. In order to alleviate this interaction, when the first mode and the second mode are sequentially completed, the generator 130 may immediately execute the second mode while excluding the first mode until reset. In other words, after the first mode and the second mode are initially executed in order and the object 90 is attracted away, the first mode is completely stopped until reset, and only the second mode can be normally performed. That is, when the object 90 approaching the danger area is detected at the second position p2, the function signal may be output immediately. The object 90 wishing to interact with the corresponding warning signal can enjoy the warning signal at the second location p2 without having to access the first location.
