Description

Smart building disaster prevention system

The invention relates to a smart building disaster prevention system, in particular to a smart building disaster prevention system with two wireless modules of GSM and Zigbee, which can issue early warning voices and fire warning voices, so that the residents can evacuate early to reduce The advantages of casualties.

According to the fire, the terrible place of the fire often occurs in the middle of the night or in the middle of nowhere. If the fire of the stars is not found early, it will often become a fire and cause serious casualties. At the beginning of the fire, the fire broke out due to inadvertent operation of the fire extinguishing device or an irreparable fire occurred in an uninhabited place. In fact, these can use the power of science and technology to reduce and avoid disasters, such as the safety of Haishan Coal Mine in the early years. When the fire was found, the fire extinguisher was thrown into the fire because the fire extinguisher would not be operated, resulting in irreparable major casualties. Recently, the Tainan ALA nightclub did not find a fire extinguisher and did not know how to use a fire extinguisher when a fire broke out. It also caused several deaths and many people were injured. Therefore, the fire-fighting guidelines proclaimed at the MRT stations of the Taipei MRT Corporation are fire fighting and notification of escape. Fire fighting is a top priority.

At present, fire extinguishers on the market are decorated like vases on the wall. When a fire breaks out, they cannot find a fire extinguisher to extinguish the fire, or they find it but do not operate so that the golden time of the fire is missed. Generally speaking, fire extinguishers are items that people don't often touch. They are often placed in the corner for several months, and nobody knows them. Even if they expire, no one knows. In the event of a fire, it will lead to serious casualties. It is a flaw in the United States.

One object of the present invention is to provide a smart building disaster prevention system, which has two wireless modules, GSM and Zigbee, which can issue early warning voices and fire warning voices, so that the residents can evacuate early to reduce the casualties.

In practice, the housing 30 can be held on one side of the fire extinguisher 21, which is a conventional technique. It is not the focus of this case, so I will not repeat it here.

The operation principle of the smart building disaster prevention system of the present case is as follows: when a fire occurs on a certain floor of the building, the second flame detecting module 25 of the fire extinguisher subsystem 20 detects a flame or a second smoke detecting. The module 26 detects smoke generation, that is, transmits the detected signal to the second microcontroller 22, and the second microcontroller 22 drives the second alarm device 27 to issue a fire voice warning and drive the The high brightness LED 26 indicates the location of the fire extinguisher 21 and is also available for escape lighting purposes.

In addition, the smart building disaster prevention system of this case also provides earthquake warning function. Usually, seismic waves can be divided into two types, the initial shaking of the P wave (Primary Wave, compression wave or longitudinal wave), and the strong shaking of the S wave (Secondary Wave, shear wave or shear wave). The emergency earthquake quick report is based on the principle that the P wave is faster than the S wave. When an earthquake occurs, the P wave detected by the seismograph close to the source is used to resolve the upcoming S wave, and the estimated source position and earthquake are immediately determined. The scale (芮氏级), based on which to predict the arrival time and earthquake of the main shocks around the country, use any feasible method to quickly release earthquake predictions and warnings. In order to be able to quickly issue an emergency earthquake report, the first observation station that monitored the earthquake near the source began to estimate the source and the size of the earthquake, the predicted arrival time and the earthquake based on the seismic wave. The Emergency Earthquake Express Report No. 1 can be issued if the number of grades in the range or the maximum magnitude may be higher than the preset reference value. After that, as time passes, the second observatory, the third observatory, and the observatory that monitors the seismic wave are gradually increasing, the available data is also increased, and all the data are combined and calculated repeatedly to improve the accuracy. Therefore, the emergency earthquake report not only maintains the speed of the first report, but also increases the accuracy with time, and repeats it several times.

When an earthquake occurs, the Seismic Sensor of the Central Meteorological Administration will transmit earthquake-related information to the telecom operators (such as Chunghwa Telecom, Taiwan Big Brother and Far EasTone, etc.), and the telecommunications operator will send a seismic newsletter to notify all mobile phone users. The second wireless module 14 of the present case can receive the earthquake newsletter from the carrier and transmit the earthquake message to the first microcontroller 12. The first microcontroller 12 will immediately drive the first alarm device 17 to issue The earthquake warning message transmits the earthquake message to the third wireless module 23 via the first wireless module 13, and the second alarm device 27 also sends an earthquake warning message to make the affected area The user provides a 10 second to 1 minute warning to allow the user to take appropriate action in time to prevent accidents.

Therefore, the smart building disaster prevention system of the present invention has two wireless modules, GSM and Zigbee, which can issue early warning voices and fire warning voices, so that the residents can evacuate early to reduce the casualties. Therefore, the smart building disaster prevention system of the present invention is indeed more advanced than the conventional technology.

The disclosure of the present invention is a preferred embodiment.
