FIG. 2 is a perspective view of a personal air respirator having a safety warning function according to a preferred embodiment of the present invention, and FIG. 3 is a block diagram of a personal care management system using a personal air respirator having a safety warning function according to the present invention.

A personal air respirator having a safety warning function according to a preferred embodiment of the present invention includes a high pressure vessel 1, a blinker 2, a high pressure regulator 3, a positive pressure regulator 4, an air breathing valve 6, A shoulder strap 10, a first respiration sensor 21, a second respiration sensor 22, an air remaining amount sensing unit 30, an alarm device (mechanical whistle) 8, a bezel 9, A body temperature sensor 40, a light emitting unit 50, a control unit 60, a motion detection sensor 61, a radio transmitter 62, a display unit 63, a power supply unit 70, an emergency structure signal input unit 80, And a management device 100.

Here, the high pressure vessel 1, the blinker 2, the high pressure regulator 3, the positive pressure regulator 4, the air breathing valve 6, the analog pressure gauge 7, the alarm device (mechanical whistle) ), The shoulder strap 10 has the same function as that of the general personal air respirator shown in Fig. Therefore, for the sake of convenience of description, the same components as those in FIG. 1 will not be described in detail.

The first respiration sensor 21 and the second respiration sensor 22 sense respiration of the user of the air respirator. The reason for using two breathing sensors here is that one can use the user's breathing detection, but two for more accurate breathing detection.

It is preferable that the respiration sensor adopts a general sensor used for respiration detection in the related field such as an oxygen sensor, a lambda sensor and a capacitive breathing sensor. In particular, the electrostatic-type breathing sensor may comprise an insulator made of an elastic insulating material, a first electrode plate provided on the upper side of the insulator, and a second electrode plate provided on the lower side of the insulator, And outputs it as a breathing detection signal.

The remaining air amount sensing unit 30 measures the amount of air stored in the high-pressure vessel 1 of the air respirator. It is preferable that the remaining air amount sensing unit 30 is also used by adopting a remaining amount sensor attached to a normal oxygen tank, LPG tank, or the like to measure the remaining amount.

The motion detection sensor 61 senses the motion of the user. It is preferable that such a motion detection sensor uses a motion detection sensor. For example, when the user's motion is detected, a motion detection signal of "1" is generated, and when the user's motion is not detected, a motion detection signal of "0" is generated.

The body temperature sensor 40 detects the body temperature of the user and generates a body temperature sensing signal. It is preferable that the body temperature sensor 40 is installed at a portion contacting the face of the sheath 9 so as to be in contact with the face of the user.

The emergency rescue signal input unit 80 generates an emergency rescue signal according to the operation of the user. The emergency signal input unit 80 preferably uses a structure signal input device such as a switch, a button, or the like.

The power supply unit 70 supplies power for driving through a built-in battery, and the light emitting unit 50 emits light according to the control of the controller 60 to generate a position confirmation signal. It is preferable that the light emitting unit 50 uses a light emitting diode (LED), and it is preferably installed on the shoulder strap 10 of the air respirator.

The controller 60 determines the state of the user according to the breath sensing signal sensed by the breath sensing sensors 21 and 22 and controls the display of the remaining air amount according to the air remaining amount sensed by the air remaining amount sensing unit 30 And controls the transmission of the status signal of the user. The control unit 60 generates a user's state signal based on the motion detection signal detected by the motion detection sensor 61 and generates a user's state signal based on the body temperature sensing signal sensed by the body temperature sensor 40 And generates an emergency rescue signal when the emergency rescue signal is generated through the emergency rescue signal input unit 80.

Wherein the status signal of the user preferably includes a member identification signal for identifying the member.

The radio transmitter 62 transmits a status signal of a user as a radio signal under the control of the controller 60. The wireless transmitter 62 may include an RF communication module for long-distance wireless communication, a Bluetooth module for short-range wireless communication, or a Wi-Fi communication module or a Zigbee communication module.

The display 63 serves to display the remaining amount of air under the control of the controller 60. [

The member management apparatus 100 receives and stores the status signal of the user sent from the wireless transmitter 62 of the air respirator, and displays the status of the user on the screen at the request of the administrator.

The member management apparatus 100 includes a member identification card recognizer 104 for recognizing a member identification card and generating a member identification signal, as shown in FIG. 4; A receiver (101) for receiving a status signal of a user wirelessly transmitted from the air respirator; A signal processor 102 for converting the status signal of the analog user received by the receiver 101 into a corresponding digital signal; Manages the activity time and personnel situation of the member on the basis of the member identification signal generated in the member identification card recognizer 104 and controls storage and display of the user's status signal generated in the signal processor 102, A control unit 105 for extracting and displaying a status signal for the user according to the user status display request input through the display unit 105; A storage unit 107 for storing the member identification signal and the user status signal under the control of the control unit 105; And an indicator 106 for displaying the status signal of the user, the activity time of the member, and the input status of the member on the screen.

The operation of the personal air respirator having the safety alarm function according to the present invention and the member management system using the same will be described in detail as follows.

First, although not shown in the drawings, a crew identification card is installed in each personal air respirator. Here, the member identification card stores information (workplace, name, unique number, etc.) for identifying the member. The information storage method may be various, such as a method using an RFID tag, a method using an IC chip, a method using a QR code, a method using a bar code, and the like, and it is assumed that an RFID tag is used in the present invention for convenience of explanation.

In addition, the control unit 60 installed in the personal air respirator also stores a member identification signal for identifying the member using the personal air respirator in the internal memory, adds the member identification signal to the status signal of the user when the data is transmitted, .

Therefore, by using such a member identification signal, it becomes possible to recognize which member is presently working in the field.

To use the personal air respirator in the field, the user first separates the member identification card from the personal air respirator. Here, the member ID card is installed and detachably attached to the ID card mounting portion. When the member ID card is detached from the ID card mounting portion, the controller 60 recognizes the start time of the member operation based on the ID card. Then, control is performed to wirelessly transmit the identified member activity time information to the member management apparatus 100. Then, the control unit 105 of the member management apparatus 100 stores the member identification signal and the member activity start time in the storage unit 107 and manages the same.

On the other hand, as another method for recognizing the member activity start time, when the member identification card is separated from the personal air respirator and submitted, the member identification card 104 of the member management apparatus 100 reads the member identification card, And stores the extracted signal in the control unit 105. The control unit 105 stores the member identification signal together with the time information in the storage unit 107 when the member identification signal is input. For example, activity time information of a specific member is stored and managed. When there are a large number of crew members on the scene, the activity time information of each crew member is stored in the same manner as described above, so that the activity time of each crew member can be known. At the same time, Command center, and command room) in real time.

The user who submitted the member identification card is equipped with a personal air respirator and is put into the field. At this time, it is preferable to operate the power switch (not shown in the drawing) immediately before starting work on the spot. When the power switch is operated, the power supply unit 70 supplies the driving power to a portion requiring power.

When power is supplied, the controller 60 initializes and then starts the control operation. Here, the light emitting portion 50 is driven as the start of the control operation. The light emitting unit 50 includes a light emitting diode (LED), and emits light under the control of the control unit 60. When the user turns on the light emitting unit 50, even if the user is unable to identify the user with smoke or the like in a state of being put into a fire scene (life rescue site) by carrying the personal air respirator, .

When the user turns on the power switch while wearing the personal air respirator and the sheath 9 is worn, the body temperature sensor 40 provided at a predetermined position of the sheath 9 detects the body temperature of the user, ). Here, since the body temperature sensor 40 is required to measure the body temperature in contact with the body of the user, it is preferable to install the body temperature sensor 40 at any position of the face body 9 which can be in direct contact with the face.

The control unit 60 adds the body temperature information detected by the body temperature sensor 40 and the member identification signal stored in the internal memory to generate a user's state signal. If the detected body temperature information is larger or smaller than the reference body temperature, an alarm signal is generated to generate a status signal of the user. . If the user's body temperature is higher than the reference body temperature, there is a fear of exhaustion due to a sudden rise in body temperature. If the user's body temperature is lower than the reference body temperature, life threat due to the low temperature may occur. Accordingly, the body temperature detection information is transmitted to the member management apparatus 100 as a radio signal in real time using the radio transmitter 62 so that the body temperature state of each member can be confirmed in real time in the control room. In the situation room, the body temperature of each member is checked. If a body temperature or hypothermia occurs, follow-up measures are taken promptly to prevent the loss of the life of the valuable member due to a rise in body temperature or a drop in body temperature. Here, it is preferable to use a wireless communication device such as a Bluetooth communication module, a Wi-Fi communication module, and an RF communication module.

Meanwhile, when the personal air respirator is operated, the first respiration sensor 21 and / or the second respiration sensor 22 sense the respiration of the user and transmit the sensed breath to the controller 60.

The control unit 60 generates a user's status signal based on the sensed breathing detection signal of the user, adds the member identification signal stored in the internal memory, and transmits the sum to the wireless transmitter 62 as transmission data. The radio transmitter 62 converts the input user status signal into a radio signal conforming to a predetermined radio standard and transmits the radio signal to the member management apparatus 100 through the antenna. In other words, it detects real-time breathing detection signal of the crew, and transmits it as a radio signal in real time.

In this case, when the respiration detection signal of the member is detected in real time and it is transmitted as a radio signal in real time, the amount of data to be transmitted may increase, which may cause communication problems. Therefore, if there is a problem in breathing, , And may be transmitted in a regular cycle (for example, one minute, five minute, etc.) in a normal breathing state.

The receiver 101 of the member management apparatus 100 receives the user's status signal generated in the personal air respirator and performs signal processing in the signal processor 102 and transmits the processed digital data to the control unit 105 as digital data. The control unit 105 stores the delivered user state signal in the storage unit 107. At this time, if an alarm signal for a life threat is included as a result of analyzing the received data, it is displayed on the indicator 106 in real time and an alarm (not shown in the drawing) is generated. Be aware in real time.

In addition, the manager of the situation room inputs information of a specific member through the input unit 103 to check the status of a specific member. For example, you can enter a specific member's name, member identification information. The control unit 105 inputs a name through the input unit 103. When a search is requested, the control unit 105 extracts status information of the member stored in the storage unit 107 and displays the status information on the display unit 106. [ This allows the administrator to remotely check the status of the crew on the scene in real time.

In addition, when the personal air-conditioner operates, the air remaining amount sensing unit 30 measures the amount of air stored in the high-pressure vessel 1 and transmits the measured air amount to the controller 60. The control unit 60 displays the air remaining amount of the air respirator of the user detected on the display unit 63. Therefore, the user can recognize the amount of air stored in the air respirator in real time. It is desirable to take appropriate action according to the amount of air that is recognized. For example, conventional personal air respirators do not have the function of measuring the remaining amount of air, and thus there is a disadvantage that the user can not confirm the amount of remaining air in the high-pressure vessel before mounting the personal air respirator. These disadvantages can lead to serious problems that can threaten the lives of users due to lack of air during operation on site. In order to solve such a problem, the present invention detects and displays the remaining amount of air remaining in the high-pressure vessel in real time, so that it is possible to confirm the remaining amount of air in real time before the user is put into the field or put in the field, It is possible to prevent life threats in advance.

In addition, the controller 60 generates a user's status signal based on the remaining-amount-of-air detection signal, if necessary, adds the member identification signal stored in the internal memory, and transmits the sum to the radio transmitter 62 as transmission data. If the detected air remaining amount is smaller than a predetermined reference, it may cause a threat to life. Therefore, it is preferable to generate the user's state signal including the alarm signal. The radio transmitter 62 converts the transmitted user state signal into a radio signal conforming to a predetermined radio standard and transmits the radio signal to the member management apparatus 100 via the antenna.

The receiver 101 of the member management apparatus 100 receives the user's status signal generated in the personal air respirator and performs signal processing in the signal processor 102 and transmits the processed digital data to the control unit 105 as digital data. The control unit 105 stores the delivered user state signal in the storage unit 107. At this time, if an alarm signal for a life threat is included as a result of analyzing the received data, it is displayed on the indicator 106 in real time and an alarm (not shown in the drawing) is generated. Be aware in real time.

Meanwhile, another feature of the present invention is that the user can detect the operation (collapse). For example, the motion detection sensor 61 senses the motion of the user and transmits the motion detection signal to the control unit 60. Here, it is preferable that the motion detection sensor 61 uses a sensor capable of detecting a fall, such as a motion detection sensor and a gyro sensor. For example, when the user's motion is detected, a motion detection signal of "1" is generated, and when the user's motion is not detected, a motion detection signal of "0" is generated.

The controller 60 accumulates an operation detection signal in the internal memory. If the motion of the user is not detected for a predetermined period of time (e.g., when only the data "0" is input for a certain period of time after the user collapses) by analyzing the motion detection signal, Generates a signal (collapsed state signal), adds the member identification signal stored in the internal memory, and transmits the combined signal to the wireless transmitter 62 as transmission data. Here, it is preferable that the motion detection signal includes an alarm signal. The radio transmitter 62 converts the transmitted user state signal into a radio signal conforming to a predetermined radio standard and transmits the radio signal to the member management apparatus 100 via the antenna.

The receiver 101 of the member management apparatus 100 receives the user's status signal generated in the personal air respirator and performs signal processing in the signal processor 102 and transmits the processed digital data to the control unit 105 as digital data. The control unit 105 stores the delivered user state signal in the storage unit 107. At this time, if an alarm signal for a life threat is included as a result of analyzing the received data, it is displayed on the indicator 106 in real time and an alarm (not shown in the drawing) is generated. Be aware in real time. By taking quick action afterwards, it is possible to prevent a crew who is on the scene from losing his life even if he falls down during the work.

Meanwhile, another feature of the present invention is that a user put in the field can generate an emergency rescue signal. For example, a user who wears a personal air respirator and is put into the field and performs a task operates the emergency structure signal input unit 80 when it is determined that an emergency structure is necessary. If an emergency rescue signal is needed here, there may be various situations, such as when one's life is threatened or another person's life is dangerous.

When the emergency rescue signal input unit 80 is operated, an emergency rescue signal is generated and input to the control unit 60. [ When the emergency rescue signal is generated, the control unit 60 generates a user's state signal based on the generated emergency rescue signal, adds the member ID signal stored in the internal memory, and transmits the combined signal to the wireless transmitter 62 as transmission data. Since the emergency rescue signal generated here may pose a life threat, it is desirable to generate a user's state signal including an alarm signal. The radio transmitter 62 converts the transmitted user state signal into a radio signal conforming to a predetermined radio standard and transmits the radio signal to the member management apparatus 100 via the antenna.

The receiver 101 of the member management apparatus 100 receives the user's status signal generated in the personal air respirator and performs signal processing in the signal processor 102 and transmits the processed digital data to the control unit 105 as digital data. The control unit 105 stores the delivered user state signal in the storage unit 107. At this time, if an alarm signal for a life threat is included as a result of analyzing the received data, it is displayed on the indicator 106 in real time and an alarm (not shown in the drawing) is generated. Be aware in real time.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention is effectively applied to a technique for mounting a personal air respirator, recognizing the state of the user remotely, and easily confirming the user's position when the user is put into the worksite.
