Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the embodiments of the present invention, the same components in the drawings are described with the same reference numerals as much as possible, and specific descriptions of related well-known configurations or functions are omitted so as not to obscure the subject matter of the present invention. In addition, the accompanying drawings Matters expressed in may be different from the form actually implemented in the drawings schematically for easily explaining the embodiments of the present invention.

1 is a configuration diagram of a fire monitoring and extinguishing system 1 shown as an example of the present invention, a control unit 4 composed of a central processing unit (CPU), a microcomputer, a micro controller unit (MCU), and the like, and a control unit 4 A thermal imaging camera (5) connected to and detecting a fire in the air measurement and analysis equipment (3) and a control unit (4) connected to the indoor or air measurement and analysis equipment (3) of the unmanned environment monitoring station (2) are installed A temperature sensor 6 for detecting the ambient temperature, a current sensor 7 connected to the control unit 4 and sensing the current supplied to the atmospheric measurement and analysis equipment 3, and a current sensor 7 connected to the control unit 4 and measuring the atmosphere and a gas leak detection sensor (9) for detecting gas leaks in the high-pressure gas container (8) installed in the analysis equipment (3), connected to the control unit (4), and composed of a plurality of keypads or touch screens, environment settings, operation The setting unit 10 for inputting or setting modes and reference data, the memory unit 11 connected to the control unit 4 and storing operating programs, application programs and various data, the input/output interface, and the control unit 4 A display unit 12 that is connected and displays current data, setting data, operation status, etc., a solenoid valve or solenoid valve 15 that is connected to the control unit 4 and opens the outlet of the carbon dioxide fire extinguisher 14, and the control unit 4 A magnetic contactor 16 connected to and turning on/off the power supplied to the atmospheric measurement and analysis equipment 3, and a fire of the atmospheric measurement and analysis equipment 3 connected to the control unit 4 includes an alarm unit 17 that issues an alarm when there is concern or a fire occurs.

The present invention is connected to a wired/wireless communication module 21 that is connected to the control unit 4 and communicates with the management server 19 and/or the mobile terminal 20 through the wired/wireless communication network 18, and the wired/wireless communication module 21, It further includes a surveillance camera 22 that transmits data to the management server 19 and/or the mobile terminal 20 so that the site where the air measurement and analysis equipment 3 is installed can be monitored in real time.

The management server 19 further includes a computer 23 having input/output means and storage means.

The ejection pipe 13 of the carbon dioxide fire extinguisher 14 is oriented and installed toward the air measurement and analysis equipment 3 with a high fire risk, so that it can be extinguished at an early stage.

The thermal imaging camera 5 uses an infrared camera or an infrared image sensor to measure a temperature of up to 200° C. in a matter of seconds in a non-contact (indirect) way from a distance without contacting the air measurement and analysis equipment 3 or a heat source. By detecting or measuring a thermal image and inputting it to the control unit 4, it is possible to monitor and determine the occurrence of a fire.

On the other hand, when a fire occurs, smoke in the smoke shortens the visible distance and makes it difficult to find an evacuation route, but the thermal imaging camera 5 of the present invention detects heat through the smoke using an infrared method. Therefore, even if smoke is generated along with a fire, there is an advantage in that thermal images can be taken without errors because heat is sensed and imaged using infrared rays without interference.

Since the thermal imaging camera 5 detects or measures the air measurement and analysis equipment 3 or the heat source in a non-contact manner, it is possible to prevent damage or failure due to high heat or fire, thereby preventing a shortening of life.

The temperature sensor 6 detects the ambient temperature of the air measurement and analysis equipment 3, inputs the temperature to the control unit 4, and compares it with the reference temperature value previously set by the setting unit 10 and stored in the memory unit 11. If it exceeds the reference temperature value, it is judged as temperature abnormality or overheating, an alarm unit 17 gives an alarm, and the management server 19 and/or the mobile terminal 20 through the wired/wireless communication module 21 and the wired/wireless communication network 18 configured to transmit.

The temperature sensor 6 measures the air measurement and analysis equipment 3 and its surrounding temperature, but the thermal imaging camera 5 does not measure temperature, but emits (radiates) from the air measurement and analysis equipment 3. Non-contact thermal image measurement is possible by measuring the amount of infrared radiation and outputting it as an image. In other words, since measurement is possible without direct contact with the air measurement and analysis equipment (3), which is the temperature measurement target, it is possible to safely measure the high temperature measurement target due to the occurrence of fire, as well as to prevent the operation of the air measurement and analysis equipment (3). Measurements can be made without interruption.

In the carbon dioxide extinguisher 14, when the electromagnetic valve 15 is opened, carbon dioxide (CO ₂ ) charged in a liquefied state is discharged and vaporized from a bomb, covering the fire area with carbon dioxide to block the supply of air. On the other hand, as a gas fire extinguisher that extinguishes fire by cooling the surroundings, it has excellent extinguishing power as it uses carbon dioxide as an extinguishing agent and does not leave any residue after extinguishing, so it is suitable for fire extinguishing of expensive atmospheric measurement and analysis equipment (3). .

The carbon dioxide fire extinguisher 14 is rechargeable, and similar nitrogen-based fire extinguishers may be applied.

The magnetic contactor (16) blocks (OFF) the power of the air measurement and analysis equipment (3) or the entire air measurement and analysis equipment (3) in the event of overheating or fire in the air measurement and analysis equipment (3) to prevent fire. enlargement is prevented.

FIG. 4 is a fire extinguishing flow chart illustrating an example of the present invention. In a state in which a fire monitoring and extinguishing program is executed through the control unit 4, a thermal imaging camera 5 captures a thermal image of the air measurement and analysis equipment 3. The temperature sensor 6 detects the indoor temperature of the unmanned environmental monitoring station 2 or the ambient temperature of the air measurement and analysis equipment 3 and inputs it to the control unit 4 (step a), and the control unit 4 detects the temperature The thermal image input from the image camera 5 is compared with the reference value (step b), and when the thermal image is determined to be a fire, the control unit 4 uses the electromagnetic valve 15 installed at the outlet of the carbon dioxide fire extinguisher 14.

In general, only the ignition point burns 1 minute after a fire occurs, and toxic gas expands 3 minutes after a fire occurs, resulting in human casualties. It is very important to extinguish fires in the early stages (golden time), and through this, property and human damage can be protected and minimized. In addition, existing fire extinguishers and fire-related systems are configured to make it impossible to determine whether they operate normally, and in the case of automatic fire extinguishing, in the case of a place where manpower does not reside, there were various problems such as difficulty in extinguishing within the golden time, but the present invention is an early evolution By securing the golden time for fire extinguishing, it is possible to prevent initial fire extinguishing and burnout of atmospheric measurement and analysis equipment (3), and to prepare for all fire scenarios by monitoring the on-site situation and fire extinguisher operation status. It is possible to protect property by warning through the alarm unit 17 and promptly notifying the manager by pop-up through the app of the mobile terminal 20 and the web of the management server 19, and there are many fire blind spots or resident personnel. Fire can be extinguished at an early stage even in unsafe places.

The present invention provides a simple internal plan view of the unmanned environment monitoring station 2 through the app of the mobile terminal 20 or the management server 19 and/or the web of the mobile terminal 20, thereby providing indoor configuration or atmospheric measurement and analysis equipment. (3), the location of the carbon dioxide fire extinguisher 14, the thermal imaging camera 5, and the monitoring camera 22 can be easily checked.

The thermal imaging camera 5 measures the surface temperature of the atmospheric measurement and analysis equipment 3 using infrared rays, and displays white and red colors when the temperature is high, and purple and black colors when the temperature is low. The higher the value, the smaller the temperature detection error. In addition, it is useful for non-face-to-face temperature measurement because it is non-contact and has less distance restrictions.

In addition, the thermal imaging camera 5 visualizes infrared rays (heat rays) emitted by the atmospheric measurement and analysis equipment 3, which is a subject, to form an image. While the human eye or a general camera detects visible light, the thermal imaging camera (5) detects the radiant heat emitted by a heated object and displays it on the screen, so it is an atmospheric measurement and analysis equipment (3 ) can be seen, and the long-wavelength infrared rays used by the thermal imaging camera 5 pass through smoke and the like well unlike visible light, so objects behind various obstacles that cannot be seen with the naked eye can be identified, which is useful as a fire monitoring and fire extinguishing system of the present invention. do.

Reference numeral 3a is a display part of the air measurement and analysis equipment 3.

Although the present invention has been set as an example of fire monitoring and fire extinguishing of air measurement and analysis equipment (3) installed in an unmanned environmental monitoring station (2), distribution boards, distribution boards, circuit breakers, wire terminals, temperature monitoring systems, communication devices, Of course, it can be applied to objects that need to avoid secondary damage or that are difficult to maintain or repair after use, such as computer facilities, energy storage devices, data sensors, thermal imaging overheating prevention systems, industrial temperature measuring devices, and electronic PCBs.

The present invention described above is not limited to the present embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical idea of the present invention, which is in the technical field to which the present invention belongs. It is self-evident to those skilled in the art.
