As described above, in conventional sensors for monitoring infrared, visible, and infrared rays of flames generated during a fire, the basic angle of view of the lens is 45˚ in the case of the ultraviolet detector, 80˚ in the case of the infrared flame detector, and 110 in the case of the visible light detector. am.

However, the conventional sensor lenses described above do not have a large basic angle of view, so there is a problem in that a considerable number of sensors must be installed in order to monitor electrical equipment connection parts and other blind spots where the risk of fire is expected. There is a problem in that the cost required is also considerably high.

In addition, the conventional sensor lenses generally move only in the horizontal direction, so that the monitoring range is not wide, so there is a problem in that a plurality of sensors have to be installed as mentioned above.

In addition, among conventional fire detection sensors, since the infrared heat detection unit is exposed, dust or foreign substances are accumulated, and it is inconvenient to periodically remove the accumulated dust or foreign substances on the lens.

The left and right rotation detection module 110 includes an infrared flame detection unit 111 , an ultraviolet detection unit 112 , a visible light detection unit 113 , and a CO detection unit 114 formed in the front in a cylindrical column shape.

The infrared flame detection unit 111 measures the sensitivity to the infrared wavelength corresponding to 4.3um ~ 4.4um of the flame ignited inside the electrical equipment corresponding to the distribution board, the switchboard, the MCCB board, the solar connection board, and the ESS, and , preferably detects a flame by detecting a wavelength of 4.3um.

The infrared flame detection unit 111 generates carbon monoxide and carbon dioxide from a flame generated from hydrocarbons, and the infrared absorption wavelength band of carbon monoxide and carbon dioxide consists of a NBF (Narrow Band Filter) filter chip between 4.0 μm and 4.8 μm. detect carbon dioxide

On the other hand, the wavelength at which carbon dioxide generated during combustion is generated by combustion has resonance radiation in the infrared region of about 4.3 μm.

This is a characteristic spectral characteristic of carbon dioxide to be heated by the combustion heat of an object, and the infrared absorption wavelength range is between 4.0um and 4.8um.

In the infrared flame detection unit 111, an infrared band pass filter of 4.3 to 4.4 μm is used to detect the resonance radiation.

The left and right rotation detection module driving unit 120 includes a first starting point detection unit 121 and a first stepper motor 122 to drive the left and right rotation detection module 110 to rotate.

The first starting point detection unit 121 inserts a circular magnet into the rotating body because it is difficult for the first stepper motor 122 to simply calculate the starting point, and a magnetization sensor capable of recognizing the circular magnet is placed at the starting point to accurately calculate the starting point. To detect the starting point, the first stepper motor 122 rotates the left and right rotation detection module driving unit 120 to the starting point even after rotation to return it to its original position.

The first stepper motor 122 is connected to the left and right rotation detection module 110 and rotates the corresponding left and right rotation detection module 110, and is protected by the adsorption prevention cover 133 as shown in FIG. 3 .

On the other hand, the vertical rotation detection module 130 is integrally formed with the left and right rotation detection module 110 at the rear of the corresponding left and right rotation detection module 110 .

In particular, the vertical rotation detection module 130 includes a second non-contact temperature sensor 131 and an infrared heat detection unit 132 .

The second non-contact temperature sensor 131 detects a temperature change with a Negative Temperature Coefficient (NTC) having characteristics of a resistance value decreasing with a rise in temperature and a negative resistance temperature coefficient.

On the other hand, the outside of the negative temperature coefficient was insulated with epoxy to prevent component damage due to electrostatic discharge (ESD).

That is, the second non-contact temperature sensor 131 detects the ambient temperature by applying the negative temperature coefficient method of measuring the temperature change using the property that the electrical resistance rapidly drops when the voltage rises above a certain level.

At this time, the temperature value measured by the second non-contact temperature sensor 131 is compared with the temperature value measured by the infrared heat sensing unit 132 protected by the adsorption prevention cover 133 , and the corresponding infrared heat sensing unit It is preferable that it can be used as a reference value for determining whether there is a failure in (132).

In addition, at this time, when a failure occurs in the infrared heat sensing unit 132 , the fact of the failure sensor may be notified through the alarm 208 or the display unit 209 .

By detecting the fire, the

The infrared heat sensing unit 132 as described above enables non-contact measurement, can quickly and accurately check the surface temperature to diagnose deterioration, and can ensure the safety of workers because measurement is possible without direct contact with the measurement target. In addition, damage to the device itself can be minimized.

In particular, the infrared heat sensing unit 132 can safely measure a high-temperature measurement object, perform measurement without damaging or destroying the measurement object, and perform measurement without interfering with the process. Because measurements can be performed without shutting down the facility, unnecessary costs due to facility downtime can be avoided.

However, since the infrared heat sensing unit 132 cannot transmit transparent glass and acrylic, a lens such as transparent glass or acrylic cannot be formed on the front surface, so that the penetration probability of foreign substances is high, and left and right to minimize penetration of foreign substances It is positioned at the rear due to the rotation of the rotation detection module 110 and is protected by the dust absorption prevention cover 133 .

The vertical rotation detection module driving unit 140 includes a second starting point detection unit 141 and a second stepper motor 142 to drive the vertical rotation detection module 130 to rotate up and down.

The second starting point detection unit 141 inserts a circular magnet into the rotating body because it is difficult for the second stepper motor 142 to simply calculate the starting point, and a magnetization sensor capable of recognizing the circular magnet is placed at the starting point to accurately calculate the starting point. To detect the starting point, even after the second stepper motor 142 is rotated, the vertical rotation detection module driving unit 140 is rotated to the starting point to return to the original position.

The second stepper motor 142 is connected to the vertical rotation detection module 130 to rotate the vertical rotation detection module 130 so as to move up and down.

By amplifying it, it improves the detection ability to generate an ideal value without abnormal oscillation and ripple induced by external frequency.

It is possible to control the left and right rotation detection module 110 and vertical rotation detection module 130 to determine the occurrence of a fire with different reference thresholds according to temperature values, and then notify the internal situation with different messages, sounds, and lights.

The main control unit 201 converts information in which the signals sensed by the sensors of the left and right rotation detection module 110 are analog information into digital signals through analysis, ie, digitally processes the signals.

If the inspection request indicator 202 is an absurd value as a result of receiving and analyzing the value detected by the sensing units of the left and right rotation detection module 110, the main control unit 201 determines that it is a failure or inspection, Inspection requests are indicated by a color or a different blinking pattern.

The aerosol driving unit 203 may be used as an output unit that outputs DC 12V 100mA when determining an electric fire or as a contact unit of AUX.

The contact-type temperature sensor 204 measures the temperature of one or more busbars in the electrical equipment in a contact-type manner, and when the temperature above a threshold value is measured, the deterioration of the corresponding busbar is detected by the alarm 208 or the display unit 209 to prevent deterioration by generating an early notification through

For example, when the N-phase bus bar connection temperature is 50°C, the temperature rise limit is 25°C, and the ambient temperature is 40°C, the maximum allowable temperature = temperature rise limit (25°C) + ambient temperature (40°C)=25+40=65°C am.

The contact-type temperature sensor 160 determines whether the internal temperature is appropriate through (N-phase bus bar temperature-ambient temperature) × coefficient (1.1 to 1.25) < temperature rise limit (25° C.), and 12.5° C. through the calculation formula Since it is <25℃, it is judged that the internal temperature is suitable.

That is, the contact temperature sensor 160 compares the temperature (N phase bus duct temperature - ambient temperature) X coefficient (1.1 ~ 1.25) < temperature rise limit (25 degrees) 5 than the ideal temperature standard 65 degrees through the calculation formula Also, the risk of deterioration of bus duct is detected early by managing it low.

The communication unit 205 is equipped with one or several communication modules among IC2C, RS485, MOD-BUS, Wife, Can, and Bluetoots, and an electric fire detection system to which an optical sensor and a gas sensor using a plurality of radar receiving lenses according to the present invention are applied. The detection information detected by the left-right rotation detection module 110 or the vertical rotation detection module 130 while communicating with an external server or a smart terminal of an administrator who manages the electrical equipment (2) transmits to the external server to notify the internal condition of the electrical equipment (2).

The electric shock voltage detection unit 206 measures the voltage between the N-phase and the enclosure of the MCCB to check the electric shock voltage of the human body in real time.

In particular, the electric shock voltage detection unit 206 detects less than 10V as normal, pays attention to 10V or more and less than 20V, checks for 20V or more and less than 30V, and urgently detects and displays 30V or more, or informs it through the communication unit 205. .

The limits of the human body's reaction and death due to electric shock are difficult to determine because of their nature, and it is difficult to verify the results of any experiments, and it is difficult to determine uniformly for reasons such as human diversity and situational variables at the time of the disaster. In case of electric shock, the level of risk is largely determined by the size of the current, the duration of the current, the route, and the type of power source.

The effects of electric shock on the human body can be broadly divided into two categories. First, electrical signals stimulate nerves and muscles, impairing normal function, and causing respiratory arrest or ventricular fibrillation. Second, electrical energy destroys living tissue. , structural damage, etc.

The emergency power unit 207 is normally charged with a lithium polymer battery, and is used as a power source for an electric fire detection device using a light-receiving lens when power is cut off when an electric fire occurs.

The alarm 208 outputs a value detected by the sensing units included in the left/right rotation detection module 210 or the vertical rotation detection module 130 as a sound, or outputs a warning message or a warning sound in case of a dangerous situation.

The display unit 209 displays the values detected by the infrared flame detection unit 111 , the ultraviolet detection unit 112 , the visible light detection unit 113 , the CO detection unit 114 , and the infrared heat detection unit 132 . Also, if the risk of fire is expected based on the sensed value, it may be displayed.

Like the second non-contact temperature sensor 131 , the first non-contact temperature sensor 210 detects the internal temperature of an electrical installation such as a switchboard by a mechanism in which a resistance value decreases with a rise in temperature.

In addition, the infrared heat sensing unit 132 formed in the rear of the left and right rotation detection module 110 has a maximum angle of view of 120° of the light-receiving lens 101 itself and a maximum rotation angle of 120° in the horizontal direction as shown in FIG. 9B . Measurement range The maximum measurement range has an angle of view of 120° to 180°.

In addition, as shown in FIG. 9c , the infrared heat sensing unit 132 preferably has a maximum angle of view of 113° to 172° in the vertical direction with a maximum vertical rotation angle of 113°.

An electric fire detection method to which an optical sensor using a plurality of radar light-receiving lenses and a gas sensor by the system according to the present invention having the above-described configuration will be described in more detail with reference to FIG. 10 .

First, the main body 200 performs a step of receiving the value detected by the sensing units included in the left and right rotation detection module 110 and the vertical rotation detection module 130 of the electric fire detection unit 100 (S100) ).

That is, the main body 200 is measured by the infrared flame detection unit 111 , the ultraviolet detection unit 112 , the visible light detection unit 113 , and the CO detection unit 114 of the left and right rotation detection module 110 . It receives infrared, ultraviolet, visible, and CO.

Thereafter, the main controller 201 compares the value received in step S100 with the threshold value of each parameter stored in the database unit (S200).

First, the main controller 201 compares the ultraviolet light sensed by the ultraviolet light sensor 112 with a threshold (S210).

In addition, the main control unit 201 performs the step of comparing the flame value and the threshold value using the infrared wavelength sensed by the infrared flame detection unit 111 as the flame value (S220).

Also, the main controller 201 compares whether the value of the visible ray detected by the visible ray detector 113 is greater than a threshold value (S230).

The main control unit 201 receives the value detected from the sensing units included in the left/right rotation detection module 200 when the measured value is not greater than the threshold value in any one of the steps S210 to S230. Repeat the steps.

On the other hand, when the detected value of the main control unit 201 is greater than the threshold value in any one of steps S210 to S230, the main control unit 201 directly controls the CO sensed by the CO sensing unit 114 and the threshold value. performing a step of comparing them (S300).

If the CO value is not greater than the threshold value in step S300, the step S100 is repeated, and when the CO value is greater than the threshold value, the main control unit 201 performs an Electric Fire Risk Index (EFRI) A step of calculating is performed (S400).

The main control unit 201 compares the electric fire risk index (EFRI) calculated in step S400 with a reference threshold value, and displays a warning in a different form according to the comparison result (S500).

That is, the main control unit 201 outputs a warning message, a warning light, and a warning sound in different forms through the inspection request indicator 202 , the display unit 209 , or the alarm 208 according to the comparison result in step S500 . to do it

The step S500 will be described in more detail with reference to FIG. 10 .

The main controller 201 performs a step of determining whether the Electric Fire Risk Index (EFRI) is greater than or equal to a reference threshold value of 70 (S511).

In the step S511, when the electric fire risk index exceeds the reference threshold value of 70, the main control unit 201 rotates the left and right rotation detection module 110 so that the infrared heat detection unit 132 at the rear can be arranged in the front. A step of controlling the left and right rotation detection module driving unit 120 is performed (S512).

The left and right rotation detection module 200 rotates and the infrared heat sensing unit 132 disposed forward decreases the resistance value as the temperature rises. A step of receiving a value is performed (S513).

The main controller 201 compares the infrared temperature value received in step S513 with a temperature threshold value (S514).

If the infrared temperature value is greater than the temperature threshold in step S514, the main control unit 201 determines that a fire has occurred in electrical equipment such as a circuit breaker, a distribution board, a switchboard, etc., and the power supply of the power cable connected to the electrical equipment is A step of displaying a fire occurrence message and a red light together with a trip signal is performed so that it can be tripped (S515).

On the other hand, when the infrared temperature value is not greater than the temperature value threshold in step S514, the main controller 201 repeats step S100.

If the electric fire risk index does not exceed the reference threshold value of 70 in step S511, the main control unit 201 determines that the electric fire risk index (EFRI) is a different reference threshold value, that is, a reference threshold value 35 A step of determining whether it is greater than or less than 70 is performed (S521).

In step S521, when the electric fire risk index exceeds the reference threshold value of 35 and is less than 70, a fire warning message is output and a yellow light is displayed as a warning light (S522).

In the step S521, when the electric fire risk index exceeds the reference threshold value of 35 and is not included in the range of less than 70, a step of determining whether another reference threshold value is less than the reference threshold value 35 is performed (S531).

If the electric fire risk index is less than the reference threshold value of 35 in step S531, the main control unit 201 displays the fire safety message on the display unit 209 (S532).

If the electric fire risk index in step S531 is less than the reference threshold value of 35, the step S100 is repeatedly performed.
