Description

Intelligent system for preventing fire using ICT and method for preventing the same}

The present invention is an intelligent fire prevention system and operation method using ICT, which not only detects the fire that has occurred, but also detects the occurrence of fire in advance, even if the fire is not in a state of occurrence, and prevents the fire in advance. It relates to a fire prevention system and operation method.

The Fire Detection System detects smoke, heat, and sparks caused by a fire and sounds an alarm, and is the most basic equipment in fire detection and fire fighting systems.

However, the recent market trend of the firefighting industry is changing to "fire prevention" rather than "fire detection". Rather than simply recognizing a fire through a fire alarm when a fire occurs, awareness is shifting toward preventing fire by predicting the occurrence of a fire situation.

Ships are also gradually reflecting this trend. As ships become larger, the number of cases in which initial response fails are increasing worldwide. In particular, an increase in seawater temperature due to global warming inevitably increases the frequency of fires, and interests of shipyards and shipowners are increasing in ways to prevent fires in order to prevent spontaneous ignition due to the increase in temperature.

In fact, most domestic shipping companies have suffered enormous losses from fires that are presumed to be spontaneous ignition of cargo due to an increase in the temperature inside the container, so the situation is taking very seriously about the fire caused by the increase in temperature.

As such, the invention is only defined by the scope of the claims. In addition, when it is determined that related well-known technologies or the like may obscure the subject matter of the present invention in describing the present invention, detailed descriptions thereof will be omitted.

A perspective view of an intelligent sensor according to an example, FIG. 4 is a binary current signal graph according to an embodiment of the present invention, and FIG. 5 is a temperature value transmitted through a 2-wire power line communication loop according to an embodiment of the present invention. It is a figure showing the state of output, and FIG. 6 is an exemplary illustration in which different fire prevention controls are performed according to temperature changes according to an embodiment of the present invention, and FIG. 7 is a different fire for each cargo area according to an embodiment of the present invention. This is an example illustration of performing preventive control.

The present invention is equipped with ICT (Intelligent Communication Technology) in the temperature sensor to monitor the temperature in real time in various areas including the cargo hold of the container ship, and when the temperature rises, spontaneous ignition is possible by lowering the temperature of the cargo area including the operation of a ventilation fan. Try not to get up.

Conventionally, as shown in FIG. 1, thermister, PT100 ohm, thermo couple, etc. are commonly used, and a transmitter is installed to output 4-20mA to the temperature sensor to display the temperature. The temperature sensor is equipped with a 3-wire cable to the transmitter, and at the rear of the transmitter, an output of 4-20mA displays the temperature value. In place of the transmitter, an I.O. module is also used. For example, if you install 100 temperature sensors, you will need 100 I/O cards or transmitters, and 300 3-wire cables will be required. This method is inevitably consumes a lot of cables, and requires a large amount of I/O cards, requires a lot of installation cost, and is not suitable for long distance use.

On the contrary, the present invention enables two wire loop power line communication using only two wires for hundreds of sensors, and can receive information about the location (Address) of the area and temperature in real time by using a module using ICT communication technology. Therefore, through monitoring, fire can be prevented in advance when the temperature rises. As an exception, when a lot of power from the sensor is required, it can be used by applying a separate power. Therefore, if a loop is configured as in the present invention, up to 127 temperature sensors can be installed using one loop card, and communication is possible up to a distance of 4km. Not only will the equipment cost be reduced, the construction time will be shortened, but the installation materials will be significantly reduced.

To this end, the intelligent fire prevention system using the ICT of the present invention may include a 2-wire power line communication loop 100, an intelligent sensor 200, and a main control panel 300, as shown in FIG. 2.

The 2-wire power line communication loop 100 includes a (+) line for transmitting an operating voltage and a current signal, and a (-) line that is arranged in parallel with the (+) line and becomes a reference voltage of the (+) line. do. That is, the communication loop consists of a loop line with a (+) line and a line with a (-) line. Therefore, the intelligent sensor 200 and the alarm (not shown) are connected to one communication loop.

The intelligent sensor 200 is a plurality of sensors connected to the (+) line and the (-) line of the 2-wire power line communication loop 100. The intelligent sensor 200 converts a sensor output value including a sensing value, a sensor address value, and a malfunction alarm signal into a current signal and transmits it to the loop card 310 through the 2-wire power line communication loop 100.

The intelligent sensor 200 may include a detection sensor module 210, an ICT module 220, an isolator module 230, and an internal temperature sensor module 240 as shown in FIG. 3.

The detection sensor module 210 is a module that detects a sensing value. The detection sensor module 210 may be implemented as a temperature sensor module that measures temperature. Preferably, it may be implemented as an NTC thermistor, a PTC thermistor, PT100, PT1000, or a thermocouple that measures temperature. NTC thermistors, PTC thermistors, and thermocouples have a temperature coefficient and are based on continuously changing electrical resistance and have a correlation coefficient inversely proportional to temperature.Because they consume less power, more sensors can be connected to the loop than other sensors. It is economical, and it is possible to implement various functions such as temperature correction, disconnection, and emergency recovery function in case of short circuit by using ICT (Intelligent Communication Technology) module. PT100 and PT1000 are the same as other temperature sensors, but because they require a lot of consumed power, they can be implemented by supplying separate power.

The ICT module 220 (Intelligent Communication Technology module) is connected to the (+) line and the (-) line of the 2-wire power line communication loop 100, and can give its own address and output sensing output. When transmitting, data including its own address is transmitted, and a signal can be sent even if an abnormality occurs through a self-diagnosis function. Therefore, it is possible to manage the history of the exact location of an accident in the event of a specific matter (fire, error, etc.) by memorizing its own address.

In addition, the ICT module 220 converts the sensor output value in a decimal form including the sensing value measured by the detection sensor module 210 into a binary current signal, and the main control panel 300 through the ICT module 220 It includes a CPU (221) to transmit to the loop card (310). For reference, a binary current signal graph is shown in 5, and the self address, current status, and measured temperature value can be converted to binary and transmitted.

The isolator module 230 performs switching to maintain the line when the 2-wire power line communication loop 100 is disconnected or shorted. The isolator module 230 may be implemented as a PCB that is embedded and inserted into the lower part of the sensor because it must perform a role of emergency recovery of the line in case of disconnection or short circuit of the 2-Wire line.

The internal temperature sensor module 240 measures the internal temperature of the intelligent sensor 200 to detect whether the intelligent sensor 200 is abnormal. Accordingly, the ICT module 220 may determine whether the intelligent sensor 200 is abnormal through self-diagnosis through the internal temperature sensor module 240.

On the other hand, the main control panel 300 displays the sensor output value received from the intelligent sensor 200, and the intelligent sensor 200 converts the sensor output value in decimal into a binary current signal to the loop card 310. Upon transmission, the main controller panel restores and outputs a binary current signal to a decimal sensor output value.

To this end, the main control panel 300 includes a loop card 310, a display panel 320, and an MCU (not shown).

The loop card 310 is a (+) terminal to which the (+) line of the 2-wire power line communication loop 100 is connected and a (-) terminal to which the (-) line of the 2-wire power line communication loop 100 is connected. Is prepared. Up to 255 detectors and ICT modules connected to the loop card 310 are possible.

The display panel 320 is a display means for displaying a sensing value of each intelligent sensor 200.

The MCU (not shown) performs a function of restoring a current signal received from each intelligent sensor 200 through a loop card to a sensor output value. For example, when the detection sensor module 210 is implemented as a temperature sensor module, a temperature value is transmitted to the main control panel 300 through the 2-wire power line communication loop 100 as shown in FIG. 5 and displayed. The temperature value can be displayed through the panel 320. Therefore, the temperature value and self address data measured through various temperature sensing sensors such as NTC thermistor, PTC thermistor, PT100, PT1000, thermocouple, etc. are converted from decimal to binary through the CPU and converted into analog data through power line communication. It is transmitted through digital communication, and the transmitted analog value is received by a loop card 310. The received binary analog data is converted back to decimal in the main control panel 300, and the position information and temperature of the temperature sensor module are displayed on the display panel 320.

On the other hand, the smoke detection system (Smoke Sampling System) is typically used as a fire detection equipment for cargo carriers including container ships. A pipe for smoke intake (diameter 15-20mm) is installed in the cargo area and exhaust fan (Exhaust Fan Unit) is operated to detect fire smoke by continuously inhaling air from the pipe.

The smoke detection system is the principle that when smoke occurs in the event of a fire, the smoke enters a smoke sampling panel along the suction pipe, and an internal smoke detector detects the smoke and sends a fire signal. . With such a relatively simple principle, it has been continuously installed on many container ships and cargo ships so far.

However, in recent years, due to the enlargement of ships, super-large ships with a hull length exceeding 400m have been built, and the number of cargo holds has increased from 4-6 to 12 or more, and the length of the suction pipe is also There was a situation in which it was extended to more than 400m.

Existing fire detection allowable time is within 300 seconds according to the law (FSS code Ch.10-2.4.2), but sometimes it exceeds 300 seconds in the case of a cargo hold located at the bow. In fact, if the fire reaction time is 300 seconds, the fire has progressed so that it is impossible to extinguish it, so initial extinguishing is not possible.

To improve this, the MCU of the main control panel 300 of the present invention is implemented to perform different fire prevention control for each area according to the received sensor output value. For example, if the sensing value is a temperature, different fire prevention controls are performed for each temperature as shown in FIG. 6.

To this end, the MCU of the main control panel 300 calculates a zone environment value for each zone in the space by using the sensor output value detected in the zone where the intelligent sensor 200 is installed, and for each zone according to the calculated zone environment value. It determines whether the sensor is in a malfunctioning state, a possible ignition state, or a fire state, and performs different fire prevention control according to the state identified for each area.

Here, the zone environment value may correspond to the temperature value of each zone, and according to the temperature value of the zone, it is necessary to determine whether a sensor is in a malfunctioning state, a possible ignition state, or a fire occurrence state, and perform a fire prevention response accordingly.

For example, a cooling fan is operated in an area where the temperature is high and there is a possibility of ignition, and a fire alarm is generated in case of a fire. Furthermore, when the cooling fan is operated, the intensity of the cooling fan is controlled differently according to the ignition possibility level. For example, as shown in Fig. 7, in the case of the A zone where the ignition possibility is the first level, the cooling fan of the first century In the case of Zone B, which is a second level with a higher probability of ignition than the first level, it is driven by a cooling fan of the second century, which is stronger than the first level, and the third level, which has a higher ignition probability than the second level, is the C zone. In the case of, it is driven by a cooling fan of the third century, which is stronger than that of the second century, so that customized fire prevention control for each zone is achieved. If a fire occurs in area D, a fire alarm is generated within the entire ship.

Accordingly, the present invention can compensate for the disadvantages of the smoke sampling system, which is a fire detection system currently used, and thus can significantly reduce human and property damage.

On the other hand, calculating the area environment value for each area calculates the area environment value by comprehensively considering the gas amount, smoke amount, heat, flame, pressure, and water level as well as temperature.

To this end, the detection sensor module 210 includes a gas sensor module that detects the amount of gas in addition to the temperature sensor module, a smoke sensor module that detects the amount of smoke, a thermal sensor module that detects heat, and a flame sensor module that detects a flame. , At least one pressure sensor module that senses pressure, and a water level sensor module capable of measuring a water level by detecting water may be further included.

Therefore, by applying the temperature, gas amount, smoke amount, heat, flame, pressure, and water level sensed in the area where the intelligent sensor 200 is installed to a preset algorithm, it is possible to calculate the area environment value for each area.

For example, a temperature score according to a temperature measured in an area, a gas score according to an amount of gas measured in an area, a smoke amount score according to an amount of smoke measured in an area, a flame score according to a flame measured in an area; The average value obtained by summing up the pressure score according to the pressure measured in the area and the water level score according to the water level measuring the location of water in the area is calculated as the area environment value. Determine whether it is in a state of occurrence and take appropriate fire prevention response.

Therefore, the present invention makes it possible to easily install a temperature sensor module, a gas sensor module, a smoke sensor module, a heat sensor module, a flame sensor module, a pressure sensor module, a water level sensor module, etc. in an area through the 2-wire power line communication loop 100. Thus, it is possible to perform the most appropriate fire prevention control by calculating an optimized area environment value through the plurality of sensor modules.

8 is a flowchart of an intelligent fire prevention method using a 2-wire power line communication loop according to an embodiment of the present invention.

A two-wire power line communication loop 100, a plurality of intelligent sensors 200 that convert the sensor output value into a current signal and transmit it to the loop card 310 through the 2-wire power line communication loop 100, and each intelligent The intelligent fire prevention system using the ICT of the present invention with the main control panel 300 including the MCU that restores the current signal received from the sensor 200 to the sensor output value and displays it on the display panel 320 prevents fire. As shown in FIG. 8, the intelligent fire prevention method includes a process of collecting environment value data for each area (S810) for collecting environment value data for each area through each intelligent sensor 200, and calculating the area environment value for each area. The process of calculating the area environment value (S820), the process of determining whether a sensor is in a malfunctioning state, a possible ignition state, or a fire state for each area according to the area environment value (S830), and the state identified for each area. Therefore, a fire prevention control process (S840) for performing different fire prevention control may be included.

In detail, the process of collecting environment value data for each area (S810) is a process of collecting environment value data for each area through each intelligent sensor 200. For example, in the case of a ship, environment value data is collected for each cabin area within the ship, and this environment value data is used for temperature, gas volume, and temperature in the area through the intelligent sensor 200 connected to the 2-wire power line communication loop 100. Environmental data such as smoke amount, heat, flame, pressure, and water level can be collected.

In collecting environmental value data, the sensor output value in decimal number of each intelligent sensor 200 is converted into a current signal in binary number and transmitted, and the main controller panel restores the current signal in binary number to sensor output value in decimal number. To collect.

The process of calculating the area environment value (S820) is a process of calculating the area environment value for each area by calculating the environment value data.

Here, the zone environment value may correspond to the temperature value of each zone. Furthermore, the zone environment value can be calculated by comprehensively considering gas amount, smoke amount, heat, flame, pressure, and water level as well as temperature.

To this end, the process of calculating the area environment value (S820) applies the temperature, gas amount, smoke amount, heat, flame, pressure, and water level detected in the space in which the intelligent sensor 200 is installed to a preset algorithm, Can be calculated. For example, a temperature score according to a temperature measured in an area, a gas score according to an amount of gas measured in an area, a smoke amount score according to an amount of smoke measured in an area, a flame score according to a flame measured in an area; The average value can be calculated as the area environment value by summing all the pressure score according to the pressure measured in the area and the water level score according to the water level measuring the location of water in the area.

The state grasping process (S830) is a process of determining whether a sensor is in a malfunctioning state, a possible ignition state, or a fire occurrence state for each area according to the area environment value. For example, if the zone environment value is out of the preset allowable range, it is judged as a sensor malfunction, and if the temperature of the zone environment value is within the first range, it is judged as a possible ignition state, and the temperature of the zone environment value is outside the first range. If it is, it is determined as a fire condition.

In the fire prevention control process (S840), different fire prevention controls are performed according to the state identified for each zone.

In other words, in case of sensor malfunction, a sensor error is displayed. In case of possible ignition, the cooling fan provided in the area is operated, in case of fire, a fire alarm is generated, and when the cooling fan is operated, depending on the level of ignition possibility. Differently controls the strength of the cooling fan.

For example, a cooling fan is operated in an area where the temperature is high and there is a possibility of ignition, and a fire alarm is generated in case of a fire. When the cooling fan is operated, the intensity of the cooling fan is controlled differently according to the ignition potential level.For example, as shown in Fig. 7, in the case of the area A where the ignition potential is the first level, the cooling fan of the first century is driven. In the case of Zone B, which is the second level with higher ignition potential than the first level, the cooling fan of the second century, which is stronger than the first century, is operated, and in the case of the third level C zone, where the possibility of ignition is higher than the second level. It is driven by a cooling fan of the third century, which is stronger than that of the second century, so that customized fire prevention control for each zone is achieved.
