The sensor 133, the camera 134, the speaker 135, the microphone 136, the memory 137, the communication device 138, the battery 139, and the determination control device 140 are configured.

Vibration detection sensor 131 is one of the sensing means for detecting the vibration generated in the helmet 100, the helmet 100 of the present invention preferably detects the vibration due to the external impact, rather than a weak vibration.

IR sensor 132 is one of the detection means using the IR to detect the presence of the object in the front, the sensor for checking whether there is an object in front of the user when the user's field of view is not secured because of fog or smoke to be. Therefore, the IR sensor 132 is mounted on the inner housing 120 to be electrically connected to the determination control device 140, but emits IR toward the front of the helmet 100 through the hole formed in the outer housing 110. .

The gas sensor 133 is one of the sensing means for detecting the amount of gas generated around the helmet 100, the amount of harmful gas such as carbon dioxide (CO2), ammonia (NH3), or oxygen (O2) ) Is a sensor to detect the amount. That is, when the amount of harmful gas such as carbon dioxide or ammonia increases more than the set schedule, the control unit 140 controls to generate an alarm sound or to generate an alarm sound when the amount of oxygen decreases below a certain level. can do.

And it is preferable that the gas detection sensor 133 is configured to be replaceable in some cases. That is, when the fire safety officer uses the helmet 100 of the present invention, since the gas generated at the fire scene is different depending on the fire scene, the gas detection sensor 133 capable of detecting the corresponding gas is helmet. It must be mounted on (100). Therefore, when the gas detection sensor 133 is configured to be replaceable, the gas detection sensor 133 suitable for the gas generated at the fire site may be mounted on the helmet 100.

The camera 134 is mounted on the inner housing 120 and electrically connected to the determination control device 140, and stores the image coming into the lens of the camera 134 through the hole of the outer housing 110 in the memory 137. The data is converted into data and output. At this time, the camera 134 is preferably installed in the front of the housing so that the user can shoot in the same direction as the eyes of the user wearing the helmet 100, the helmet 100 to shoot the situation of the back of the user's eyes do not reach It can also be installed at the back of the panel.

The camera 134 may be a camera 134 for capturing a general video, but an infrared camera 134 may be installed for capturing a dark environment with little light.

The speaker 135 is installed to output sound toward the inside of the inner housing 120. When the user wears the helmet 100, the speaker 135 is mounted at the position closest to the user's ear.

The microphone 136 is installed inside the inner housing 120 and is mounted at the position closest to the user's mouth when the user wears the helmet 100.

The memory 137 is used as a storage means for storing data on the surrounding physical environment sensed by the sensing means such as the vibration sensor 131, the IR sensor 132, and the gas sensor 133. 137) or the like is preferably used, and can be easily detached from the helmet 100 as necessary in the future, so that the contents stored in the memory 137 can be easily checked by an external device such as a PC.

In this case, the data stored in the memory 137 is not only data about the surrounding physical environment detected by the sensing means such as the vibration sensor 131, the IR sensor 132, and the gas sensor 133, but also the camera 134. Also, the image may be recorded through the image, the sound output through the speaker 135, the sound input through the microphone 136, and data about a signal communicating with the outside through the communication device 138. That is, of course, all data generated through the helmet 100 of the present invention can be stored.

The communication device 138 includes an external communication device 138a and an internal communication device 138b.

The external communication device 138a is provided for the user wearing the helmet 100 to communicate with other external users. For example, in the case of fire safety personnel, the external communication device 138a is provided for communication with the fire command center. Therefore, the communication standard used for the external communication device 138a is preferably wireless communication using a communication standard such as WiBro, WiMAX, WiFi, HSDPA.

The internal communication device 138b is provided for a signal received by a user wearing a helmet 100 or received from other equipment in the vicinity, for example, when a fire safety agent enters a fire scene, When the oxygen tank enters the fire, etc., when the pressure of oxygen in the oxygen tank decreases below a certain level, it may not be confirmed. Therefore, the pressure of oxygen in the oxygen tank is increased. If it decreases below a certain level, the oxygen tank side is provided to receive an alarm signal.

Therefore, since the communication standard used for the internal communication device 138b is performed at a short distance, it is preferable to perform wireless communication using a short range communication standard such as Bluetooth or Zigbee.

The battery 139 is provided to supply power required for the electronic device 130 of the helmet 100.

The determination control device 140 performs a function as a determination means for determining whether a value detected by the detection means such as the vibration detection sensor 131, the IR sensor 132, and the gas detection sensor 133 changes more than a predetermined level. As described above, when it is determined that an abnormal phenomenon occurs such that the data sensed by the sensing means is changed to a predetermined level or more, the controller 420 stores the data in a storage means such as the memory 137.

However, the determination control apparatus 140 controls to store the data sensed by the sensing means in the memory 137 even when the phenomenon detected by the sensing means does not change more than a certain level. The determination controller 140 controls the data stored in the memory 137 to be sequentially stored with time. If there is no more space for storing data in the memory 137, a space for storing the first stored data is secured according to time.

That is, the determination control device 140 stores the data sensed by the sensing means in the memory 137, and stores the data corresponding to the time when the data sensed by the sensing means changes at regular intervals according to time. Control to save. Therefore, even if there is not enough space to store in the memory 137, it is possible to continuously store the sensed data without requiring any special operation.

At this time, when an abnormal phenomenon occurs in which the data sensed by the sensing means is changed to a predetermined value or more among the data stored in the memory 137, the data stored in the memory 137 is not deleted and kept.

In addition to the above control, the determination control device 140, when a signal is received from the external communication device 138a or the internal communication device 138b, the signal is transmitted to the user through the speaker 135 or the like. By transmitting the received signal or the signal output from the microphone 136 to the external communication device 138a performs a function of controlling the communication between the user wearing the helmet 100 and the outside.

That is, the helmet 100 of the present invention is equipped with a detection means such as a vibration sensor 131, IR sensor 132 and gas sensor 133 that can detect the physical environment around the helmet 100 In response to detecting that the data detected by the sensing unit is changed to a predetermined schedule or more, the user wearing the helmet 100 is notified through the speaker 135 and the like, and the detected data is stored in the memory 137 or the like. By storing through the device, when an accident occurs to the user wearing the helmet 100, it can be confirmed later using the data stored in the storage means.

Meanwhile, in addition to the plurality of electronic devices 130 described above, the helmet 100 of the present invention may include a position tracking (GPS) system capable of tracking the position of the helmet 100 and a clock capable of knowing time. In addition, when the data sensed in the memory 137 is stored, the time of the accident and the position of the helmet 100 may be stored together.

In addition, the helmet 100 of the present invention can also be equipped with a head lamp or the like that can ensure the view of the user wearing the helmet 100 by irradiating light in a dark place.

<Description of the method>

A method of storing data about the physical environment around the helmet 100 according to the present invention will be described with reference to the flowchart shown in FIG. 4, and the order of convenience will be described with reference to FIGS. 2 and 3.

1. Detection step <S401>

Vibration or gas corresponding to the physical environment around the helmet 100 is sensed using sensing means such as a vibration sensor 131, an IR sensor 132, and a gas sensor 133. That is, the vibration sensor 131 detects the vibration of the helmet 100 caused by the external influence, the IR sensor 132 that cannot be identified by the user's eyes detects the object in front of the gas sensor ( 133 detects an amount of harmful gas or oxygen distributed around the helmet 100.

2. Judgment step <S402>

In step S401, it is determined whether the detected data changes by more than a predetermined level. For example, when the vibration of the helmet 100 is greater than the range of vibration generated when the user wearing the helmet 100 walks or runs, that is, the helmet 100 is somewhere while the user suddenly falls or loses center. It is determined whether the vibration or the like when a predetermined shock or more is applied to the helmet 100 generated while hitting is detected by the vibration sensor 131.

3. First storage step <S403>

If it is determined in step S402 that the data is changed to a predetermined value or more, the data detected in step S401 is stored in the storage means such as the memory 137 for a predetermined time before and after the time determined in step S402. The data stored in the step is stored without being deleted by the user.

That is, at this time, the stored data can check the circumstances in which the user has been in an accident by checking the data stored in the memory 137 when the user wearing the helmet 100 has an accident. Therefore, the data stored for a predetermined time after the determined time together with the data stored for a predetermined time before the time determined based on the time determined in step S402 are stored so as not to be automatically deleted together.

The data stored in this step is not only the data detected in step S401, but also an image captured by the camera 134, a sound output through the speaker 135, a sound input through the microphone 136, and a communication device ( Data about a signal communicating with the outside through 138 may be included. That is, of course, all data generated through the helmet 100 of the present invention can be stored.

4. Storage space determination step <S413>

If it is determined in step S402 that the data does not change more than a certain amount, it is determined whether the memory 137 runs out of storage space in which the data sensed in step S401 can be stored.

5. Second storage step <S414>

If it is determined in step S413 that the storage space of the data is not insufficient, the data detected in step S401 is sequentially stored in the order of time. At this time, the interval in which the data is stored may be stored at regular time intervals, or may be stored only at the moment when the value of the first detected data changes.

The data stored in this step is input through the microphone 136, as well as the data detected in step S401, as well as the image captured by the camera 134, the sound output through the speaker 135, as in step S403 A sound, data about a signal communicating with the outside through the communication device 138 may be included. That is, of course, all data generated through the helmet 100 of the present invention can be stored.

6. Delete and save step <S424>

However, if it is determined in step S413 that the data storage space is insufficient, since the data sensed in step S401 can no longer be stored in the memory 137 or the like, the data is no longer stored, but first in the order of time. The stored data is deleted to secure a space for storing data in the memory 137, and then the data sensed in step S401 is subsequently stored. Therefore, it is possible to continuously store the data sensed in step S401 without the user's special operation.

At this time, the data stored in step S403 is not automatically deleted in this step. In other words, the data stored in step S403 are classified as data stored for a specific situation and are not deleted due to lack of storage space in this step, and only the data stored in step S414 is automatically deleted and only the newly input data is stored.
