Description

Fire detection device {Apparatus for Monitoring Fire}

The present invention relates to a complex sensor fire detection, and more particularly, to detect heat, smoke, flame, or combustion products generated in the event of a fire to induce safe and rapid evacuation in the event of a fire, and initiate firefighting activities for early suppression of a fire. It relates to a composite sensor fire detection device and method for notifying.

A fire detector is a device for early detection of a fire by using heat or smoke generated in the event of a fire. However, there are various types of fire, the installation environment for each place is different, and the choice of detectors is different. The domestic market for fire alarms is expected to grow from KRW 881.8 billion in 2016 to KRW 1.1255 trillion in 2021, with an average annual growth rate of 5.0%. , products equipped with complex sensing functions such as temperature, flame detection, and smoke are being released, and cutting-edge products that apply wireless and IoT technologies are being developed recently.

In addition, fire detectors were not installed in row houses or detached houses before the revision of the Fire Protection Act in August 2011, but independent alarm type fire detectors have been installed in newly built houses since then.

However, it is a problem that the interlocking alarm of the sensing period installed in each room inside the household is not performed, and the maintenance status of the battery cannot be checked. In addition, heat detectors were installed in apartments and officetels, but at the end of January 2015, the Fire Protection Act was revised, and smoke detectors must be installed in buildings designed from this year.

On the other hand, most buildings use low-cost fire detectors with an ON/OFF contact structure, so the occurrence rate of Unwanted Alarm is high. Accordingly, analog fire detectors capable of setting alarm levels according to temperature values or smoke concentrations are being produced, but are relatively expensive, so they are rarely used in general buildings except for high-rise buildings or five-star hotels.

In addition, efforts are being made to reduce such fire detection not only domestically but also globally. The world's fire detectors and detectors market reached $ 3 billion in 2016, and by 2021 it will grow at an average annual rate of 10.8% to $ 5.1 billion is expected to reach This market is divided into the parts market and the service market, and smoke detectors account for 52.8% of the parts market, and the service/maintenance sector accounts for 34.4% of the service market. In the case of Germany, the total fire alarm technology market including German fire alarms in 2013 was 1.36 billion euros, an increase of 4.6% compared to the previous year, and the growth trend has continued for the past three years. In Germany, although the price range is high, preference for wireless network type fire alarms that automatically send signals to some manufacturers in the event of a fire is also increasing.

And in the case of China, according to estimates by market researcher CVM after surveying major competitors in the flame detector industry, such as Forney, COEN, DURAG, Honeywell, and Wendong, the size of the Chinese flame detector market in 2013 was about for 2 billion yuan

and increased by 20% compared to the previous year.

On the other hand, as a company related to IoT fire detectors, most of the domestic companies are small except for some large companies such as Samsung Electronics in the case of the domestic sensor industry. Domestic companies rely on module production by post-processing, assembly, and packaging of products based on imported sensors. Chips and prototypes are being developed for some items, but the technology gap is also significant.

Due to the lack of basic technology, the domestic sensor industry is limited to importing sensor chips and supplying them in modules. Even if chips are developed directly, there are no production facilities or testing institutes that can test and evaluate them, and technology patents are below the global average in both quantity and quality. Image sensors for mobile phones did well and accounted for 1.7% of the global sensor market production, but there has been no new growth engine since.

On the other hand, as a trend of overseas companies, the WIFIRE project, in collaboration with the San Diego Supercomputer Center (SDSC), Qualcomm Research Center, and UCSD, supports data-based predictive modeling and analysis in real time for forest fires that are likely to spread rapidly.

It is a construction case that supports fire response and resource management by processing real-time remote sensor data such as satellite data and weather, and assists rapid ecological restoration by performing analysis for forest fire prevention and response as well as vegetation management.

Germany's University of Magdelburg-Stendal has developed 'OLE (Off-road Loescheinheit)', a self-driving firefighting and disaster prevention robot capable of finding and extinguishing forest fires on its own. Olu detects forest fires and extinguishes them in the early stages with various advanced sensors, GPS devices and fire extinguishing agents built in, and also informs the fact of fire and the exact location through a wireless communication system so that firefighting helicopters can be dispatched immediately. It is known that it is possible to detect fire up to 800m away by installing a high-performance biosensor that can detect fire even by smell.

there is.

1 is a breakdown of the number of fires in administrative districts nationwide, and FIG. 2 is a diagram showing the amount of fire damage nationwide. Looking at Figures 1 and 2 (Statistics Office (2016-2019 data)) showing the breakdown of the number of fires in administrative districts nationwide and the amount of nationwide fire damage, the average number of fires in the last three years was over 40,000, ranking second among accident type statistics (No. 1 traffic accident), and early fire detection is currently prioritizing human evacuation rather than suppression.

As such, various types of fire detectors are being developed in Korea and abroad, but as of now, the existing fire detectors in Korea are single-type modules using one sensor or fire detection through a composite detector (adoption of two or more sensors). However, in order to solve the problem of frequent malfunctions and installation of multiple demagnetizers, a complex sensor detector using flame, smoke, and temperature sensors most closely related to fire is developed, and inconvenient matters are secured and commercialized to replace imported detectors and existing It will be said that the development of a sensor corresponding to the sensor is urgent.

In particular, since a fire can cause damage to life and property depending on whether or not it is extinguished within the first 3 minutes, it is necessary to create a foundation for early detection and recognition in the event of a fire, and to improve the functions of various fire detectors currently being released in the market. It is necessary to develop a comprehensive digital fire detector by integrating it, and at this time, the functions of flame and smoke detection and temperature sensor must be implemented as a single module, but fire-related flame, smoke, and temperature data are analyzed according to the site where the sensor is installed. By adjusting the sensitivity, malfunctions are minimized depending on the usage environment (for example, halogen lights are used a lot in traditional markets, malfunctions are judged as flames, and malfunctions caused by burners used in food kitchens and the resulting smoke are minimized). It is necessary to develop products that can do this.

In addition, it is equipped with wired and wireless functions to maximize the convenience of installation by easily installing it in traditional markets where installation is difficult and in environments where wired construction is difficult. It is necessary, and it is necessary to establish a fire monitoring system suitable for large buildings using sensor repeaters in case of independent installation or joint installation.

Therefore, the present invention is to solve the various disadvantages and problems of the prior art as described above, and detects heat, smoke, flame or combustion products generated in the event of a fire through a single complex sensor fire detector to safely and quickly detect a fire in the event of a fire.

4 is a view for explaining an embodiment of the ultraviolet sensor in the complex sensor fire detection device according to the present invention.

An embodiment of the ultraviolet sensor in the composite sensor fire detection device according to the present invention is as shown in FIG. 4, and the ultraviolet sensor is applied with a voltage of about VDC 350V to the electrode and discharged from the cathode by the incident ultraviolet light. It is composed of a cold cathode tube that multiplies by , and the tube of the sensor uses a metal such as NI, Mo, Ag, etc. as a quartz glass or UV-transmitting glass with good transmission of ultraviolet rays.

At this time, in the present invention, the output waveform is found at the distance where the flame is actually detected, and since noise is generated at the time when the first flame is detected, this data is filtered, and data is further acquired for 5 seconds after filtering to obtain the actual flame In order to increase the sensitivity and increase the maximum usage time, the UV TRON sensor is used with high voltage, so real-time data is not collected, and data is acquired for 5 seconds after checking for 15 seconds at the time when the flame is generated to filter the data.

6 is a view for explaining constant temperature and differential detection using a temperature sensor in the composite sensor fire detection device according to the present invention.

In the composite sensor fire detection device according to the present invention, the constant temperature and differential detection using the temperature sensor selects a sensor that is inexpensive compared to the sensor price and is safe at high temperature, and the optimal value is determined by software for the constant temperature and differential type restrictions according to the installation environment. For complex control processing, for example, the thermistor (NTC) is mainly made of polymer or ceramic material, and can measure temperature with high accuracy between -90 and 130 degrees Celsius.

A mister is different from a resistance thermometer that uses pure metal and measures high temperature. At this time, the thermistor displays a reference resistance value based on the standard 25 degrees, and a lot of difference occurs depending on the symbol. In other words, since the electrical resistance continuously decreases as the temperature rises, it is possible to acquire data using 25 degrees as the reference value, so the rate of change is non-linear, so it has the advantage of being able to prevent instantaneously changing data in the event of a fire. there is.

At this time, the data is filtered so that the temperature value does not change rapidly, and based on the currently acquired temperature, the data from 1 minute ago and the data after 1 minute are averaged to determine whether a fire has occurred. .

At this time, a communication module (for example, a LoRA module), a complex sensor such as heat, smoke, temperature, and flame, a power analyzer, and a distribution panel are configured for each store. For reference, the fire monitoring server performs management of the nationwide fire detection system including cities, counties and districts. Through this, the safety manager's smartphone information can be a store manager, building manager, market manager, etc., and depending on the company, it can be a manager of a government office. On the other hand, the fire monitoring server 200 needs to install and maintain the composite sensor fire detection device 100. In the case of a company that installs the composite sensor fire detection device 100, the installation cost is paid in installments to reduce the initial burden. Maybe. In addition, the management cost also receives a certain amount every month, but since the fire detection device parts that enter depending on the size of the complex sensor fire detection device 100 installation company are different, you will be able to receive different management costs depending on the number of installed parts. In addition, in order to accurately process such costs, that is, financial costs, it is preferable that the fire monitoring server 200 is processed in association with the financial company (card company, bank company, etc.) server 300. In the case of processing through such a financial company server 300, it is possible to process with high reliability while minimizing the cost problem between the operator of the fire monitoring server 200 and the installation company of the composite sensor fire detection device 100. In addition, for example, in the case of processing through a card company, the initial cost of installing the complex sensor fire detection device 100 can be divided into installments to minimize the financial cost of the company installing the complex sensor fire detection device 100, and the bank or card company Since it is an expenditure through the process, the details of the expenditure are accurately processed, and tax benefits will be available later.
