TECHNICAL FIELD [0001] The present invention relates to an impact detection helmet and an alarm system using the same,

TECHNICAL FIELD The present invention relates to an impact detection helmet and an alarm system using the same. More particularly, the present invention relates to an impact detection helmet capable of detecting an impact applied to a safety helmet and confirming safety of the operator, and an alarm system using the same.

In general, workers working at industrial sites such as construction sites, shipyards or mines are required to wear safety helmets.

The helmet is intended to protect the head from shocks caused by impacts or falls caused by falling objects when the worker is working, and to prevent injuries.

However, even if a helmet is worn, an external impact may be transmitted to the head of the worker, causing the worker to fall or be injured.

Therefore, it is necessary to judge whether the impact is such that the shock is applied to the helmet and the impact of the impact to the worker's head is detected. When the operator loses consciousness, it is necessary to transmit the rescue signal.

Generally, in confirming the safety of the operator, as in the prior art (Korean Patent Laid-Open No. 10-2010-0089911), it is possible to sense an external impact applied to the safety helmet using the impact sensor.

However, in addition to the sensor for measuring the impact applied to the safety helmet such as the impact sensor, it is necessary to determine whether or not an operator has worn the safety helmet, so that a detection sensor for detecting whether the worker wears the safety helmet may be further needed.

Therefore, there are many data to be compared and analyzed, and the system configuration may be complicated.

According to an aspect of the present invention, there is provided a method of detecting a change in current in a resistance circuit generated by a resistance circuit coupled to a body portion and a resistance applied to an impact applied to the body portion, And an alarm system using the same.

The resistor circuit may include a lead portion including a plurality of lead wires coupled in parallel, a resistor coupled to one end of the lead portion, and a power source connecting the resistor and the other end of the lead portion and supplying power.

In addition, the lead portion may be provided in a space between the body portion and the buffer band formed on the body portion.

The apparatus may further include a pulse sensor coupled to both side surfaces of a hair band formed on an inner circumference of the body portion in contact with the head of the operator and sensing a pulse of the operator.

The detecting unit may transmit at least one of pulse rate measured by the pulse sensor or current change of the resistance circuit to the mobile terminal.

The impact sensing helmet according to the embodiment of the present invention and the alarm system using the same can detect the impact strength through the change of the current in the lead portion and thus can be easily implemented and the safety of the operator can be effectively determined.

In addition, since the sensing unit is not influenced by impacts applied to the helmet by being installed on the chin strap, the current change detection can be stably performed.

The effects of the embodiments of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood, however, that the appended drawings illustrate the present invention in order to more easily explain the present invention, and the scope of the present invention is not limited thereto. You will know.

Referring to FIGS. 1 and 2, the impact sensing helmet according to an embodiment of the present invention includes a body 100, a resistance circuit 200, and a detection unit 300.

The body part 100 may be formed with one opening to be mounted on the head of the operator.

The body part 100 can be attached to the head of the worker to protect the head of the worker. Therefore, a shock absorber (not shown) for mitigating an impact may be provided inside the body part 100. [

In addition, a buffer band 110, a hair band 120, and a chin strap 130 may be coupled to the body 100.

The cushioning band 110 and the hair band 120 can separate the inner surface of the body part 100 from the head of the operator when the operator wears the body part 100 and can cover the head of the operator.

The chin strap 130 is provided on both sides of the body part 100 and can be fixed so that the body part 100 is not shaken by binding the chin strap 130 to the chin of the worker.

Meanwhile, the resistor circuit 200 may be coupled to the body 100.

3 and 4, the resistance circuit 200 of the impact sensing helmet may include a lead 210, a resistor 220 and a power supply 230 according to an embodiment of the present invention.

The wire portion 210 may include a plurality of wires coupled in parallel.

That is, a plurality of the lead portions 210 may be spaced apart along the inner curved surface of the body portion 100. One end and the other end of the plurality of lead wires are connected to the anode electrode 210a and the cathode electrode 210b, .

The lead wire 210 may be provided in a space between the body 100 and the buffer band 110 formed on the body 100.

That is, the buffer band 110 can prevent the head of the operator from directly contacting the lead portion 210.

Although the electric current flowing in the lead wire 210 may not be harmful to the human body, in order to ensure the safety of the worker, a space between the buffer band 110 and the inner surface of the body 100 .

Meanwhile, a case (not shown) of an insulating material that surrounds the respective lead wires or surrounds the lead wires 210 so as to protect the leads of the lead wires 210 from the sweat or dust of the operator and secure the safety of the operator, May be provided.

However, such a case may be formed of an elastic material so as not to interfere with the deformation of the lead wire portion 210.

The resistor 220 may be coupled to one end of the lead portion 210.

The power supply 230 connects the resistor 220 and the other end of the lead wire 210 to supply power.

When the power supply 230 is turned on, power can be supplied to the resistor 220 and the lead wire 210.

At this time, when an external impact is applied to the body 100, the length of at least one of the wires included in the wire 210 may be long or broken.

In general, when the length of the conductive wire becomes long, the resistance becomes large, and the overall resistance of the conductive wire portion 210 becomes small. Therefore, the current of the resistor circuit 200 is increased.

As described above, the entire resistance value of the wire portion 210 changes as the length of the wire becomes longer or shorter, thereby measuring the current across the resistor 220 and detecting the current change of the resistor circuit 200 .

The current change is detected by the detecting unit 300 to be described later, and when the current change exceeds the set value, the operator recognizes that the current is dangerous and can transmit an alarm signal through the mobile terminal 400. [

The detecting unit 300 and the mobile terminal 400 will be described later in detail.

The resistor 220, the power source 230 and the detecting unit 300 may be coupled to the chin strap 130 coupled to the body 100.

The resistor 220 and the power source 230 may be coupled to the chin strap 130 as opposed to the lead wire 210 coupled to the inside of the body 100.

2, the anode electrode 210a and the cathode electrode 210b of the lead wire 210 extend from the lead wire 210 and are connected to the resistor 220 and the power supply 230 through the chin strap 130, So that the resistor circuit 200 can be formed.

By separating the resistor 220 and the power supply 230 from the body 100, it is possible to prevent the resistor 220 and the power supply 230 from being damaged by the impact even if an impact is applied to the body 100 have. Therefore, it is possible to stably detect the current change across the resistor 220. [

On the other hand, the detection unit 300 can detect the current change of the resistance circuit 200 generated by the impact applied to the body 100, as described above.

That is, the detecting unit 300 may be coupled to the chin strap 130 so as not to be affected by the impact applied to the body 100, like the resistor 220 and the power source 230, It is possible to detect the current change of the resistance circuit 200 by comparing the detected current with the initial current.

The current change of the resistance circuit 200 detected through the detection unit 300 can be transmitted to the mobile terminal 400. In the meantime, the present invention can indicate whether an accident occurred by an operator by using an alarm signal using the mobile terminal 400.

The alarm system using the impact sensing helmet may further include a mobile terminal 400 and a server 450 so that an alarm signal can be transmitted according to an accident of an operator.

Referring to FIG. 5, the mobile terminal 400 may transmit an alarm signal to the operator according to the current change of the resistance circuit 200 transmitted from the detection unit 300.

The mobile terminal 400 may have stored therein a range of a current change indicating a danger level.

Specifically, when the detection unit 300 transmits the current change of the resistance circuit 200 detected to the mobile terminal 400, the current change of the current received by the mobile terminal 400 is compared with the danger level Thereby determining whether the operator is at risk.

The danger level current change value stored in the mobile terminal 400 can be determined by comparing the intensity of an impact that an operator may be injured by an experiment with the body part 100 mounted and the current change of the resistance circuit 200 Can be obtained.

Therefore, the safety of the operator can be judged from the current change of the resistance circuit 200. [

If the current change of the resistance circuit 200 caused by the shock applied to the body 100 exceeds the danger level, the mobile terminal 400 may transmit an alarm signal to be recognized by the operator.

The alarm signal may be a voice signal, for example, an alarm sound or a warning sound.

Meanwhile, the server 450 may receive the rescue signal from the mobile terminal 400.

That is, even if the alarm signal is transmitted from the mobile terminal 400, the alarm signal may be canceled by the operator if the operator is safe.

However, if the alarm signal is not released within a predetermined time, the mobile terminal 400 can transmit the rescue signal to the server 450.

Thus, the alarm signal is continuously transmitted, the operator does not release the alarm signal, and the mobile terminal 400 determines that the operator is in danger of an accident and can transmit the rescue signal to the server 450.

The server 450 can inform the rescue personnel or the manager when the rescue signal is transmitted, and can confirm the safety of the operator.

As described above, the impact sensing helmet and the alarm system using the impact sensing helmet according to an embodiment of the present invention can determine the intensity of impact applied to the body part 100 by only changing the current of the resistance circuit 200, It can be judged.

The body part 100, the resistance circuit 200, the mobile terminal 400, and the server 450 may include the impact sensing helmet according to an embodiment of the present invention described above with reference to FIGS. 1 to 5, May be the same or substantially similar.

In addition, the impact sensing helmet according to another embodiment of the present invention and the alarm system using the same may further include a pulse sensor 500.

The pulse sensor 500 is coupled to both sides of the hair band 120 formed on the inner periphery of the body 100 in contact with the head of the worker described above, and can sense the pulse of the worker.

The pulse sensor 500 can measure the pulse of the worker in contact with the operator's temple and the pulse measured through the pulse sensor 500 can be transmitted to the detecting unit 300.

The detecting unit 300 may transmit at least one of the pulse rate measured by the pulse sensor 500 or the current change of the resistance circuit 200 to the mobile terminal 400.

Therefore, in the mobile terminal 400, it is possible to determine whether the operator is safe or not through the pulse of the operator or the current change of the resistance circuit 200.

If it is determined that the operator is dangerous, the mobile terminal 400 transmits a rescue signal to the server 450.

Therefore, it is possible to determine the intensity of the shock applied to the body part 100 through the current change of the resistance circuit 200, and to protect the life safety of the operator by checking the biorhythm of the worker.
