Intelligent fire notification device

The invention relates to the field of fire accident alarm systems, and more particularly to an intelligent fire site notification device that immediately informs predetermined users of the fire site and fire situation and the best escape direction and route by wireless transmission of signals so that they can quickly escape from the fire site or rush to fire fighting.

Along with the continuous improvement of safety awareness of modern people, the safety requirements of living and working environments have become higher and higher. However, there are still many events that cannot be controlled and a fire accident is an unpredictable danger. As a result of fire accidents, many people have lost their lives. In fact, some fire accidents are preventable, and when they are unavoidable, senseless casualties can be prevented if the sources of fire can be extinguished or if people can escape from the fire sites in time once a fire accident occurs.

In large buildings such as office buildings, restaurants and apartment buildings, fire sensors are usually installed on the ceilings of the building to ensure the safety of employees or residents. The function of a fire sensor is to detect a rapid or abnormal increase in temperature. If the ambient temperature increases rapidly or reaches the set maximum temperature, the fire sensor will issue a control command to trigger an alarm so that people can quickly escape from the fire scene.

However, when a fire accident occurs in some large buildings, people cannot see the exact location of the fire because there are so many rooms and there is no specific escape route. Therefore, the best escape route is easily lost. Especially in some office buildings,

In hotels or restaurants, because people are generally only temporary or short-term visitors or tenants, even if they know that there is a fire accident, they may not know the exact location of the fire and may not be able to escape from it in time because they are not familiar with the surrounding conditions, thus leading to more casualties. In addition, because every product has a lifespan, the effect of a fire sensor will decrease because it cannot be known whether the fire sensor is working normally. Therefore, people's safety cannot be precisely ensured.

Therefore, the invention proposes an intelligent wireless fire site notification device to solve the above problems.

It is therefore an object of the invention to provide an intelligent fire site notification device which informs predetermined users of the fire site and the fire situation as well as the best escape direction and the best escape route by wireless transmission of signals so that they can quickly escape from the fire site or rush to fire fighting, thereby reducing the danger to a minimum.

This object is achieved according to the invention by an intelligent fire location notification device according to claim 1. Further developments of the invention are specified in the dependent claims.

According to a feature of the invention, there is provided an intelligent wireless fire site notification device which has a learning function and can periodically perform a self-test to accurately ensure people's safety.

According to another feature of the invention, there is provided an intelligent wireless fire site notification device having an automatic fire accident dialer capable of automatically reporting a case to the police at the same time as an alarm is triggered to evacuate people when a fire accident occurs.

According to yet another feature of the invention, an intelligent

A wireless fire location notification device is provided which also has a help-seeking function for emergencies, in which at least one emergency call point arranged in remote locations of large buildings is utilized to perform the function.

According to the invention, a plurality of fire sensors are arranged in a large building, each fire sensor having a specific serial address code. A plurality of guide indicators are arranged on the walkways, while a plurality of emergency call points are arranged at remote locations in the building. A remote control master is used to wirelessly set the serial address code of each fire sensor. The mutual learning and memorization of the codes of all slaves such as the fire sensors, the guide indicators and the emergency call points are set so that the digital codes therein match. When a fire sensor detects an abnormal situation, a wireless alarm signal is sent to the remote control master and the other fire sensors and the guide indicators which have already learned the digital codes to activate them.

Further features and advantages of the invention will become clear from reading the following description of preferred embodiments, which refers to the drawings, in which:

According to the invention, an intelligent fire site notification device is arranged in a large building. The invention uses the device to immediately inform people of the fire site and the fire situation as well as the best escape direction and route by wireless transmission of signals, so that they can quickly escape from the fire site or rush to fire fighting, thereby reducing the danger to a minimum.

As shown in Fig. 1, in the invention, a fire sensor 10 is arranged in each room of a large building. Each fire sensor 10 has a specific serial address code. A plurality of guide indicators 20 are arranged on the walkways and public places. A plurality of radio emergency call points 30 are arranged in places remote from safety such as stairs and parking lots in the large building. A remote control master 40 is used to wirelessly set the serial address code of each fire sensor 10. The mutual learning and memorization of the codes of all the slaves such as the fire sensors 10, the guide indicators 20 and the emergency call points 30 are set so that the digital codes therein match. Therefore, when a fire sensor 10 detects that there is an abnormal situation, it immediately triggers an alarm, outputting a radio alarm signal to the remote control master 40 and to the other fire sensors 10 and the guidance indicators 20 that have already learned the digital codes so that all the fire sensors 10 simultaneously trigger voice alarms. The guidance indicators 20 discriminate from which fire sensor 10 the signal is sent according to the digital code when they receive the radio alarm signal, thereby determining the best escape route and simultaneously displaying the fire location and the escape route. This allows people to escape from the fire location or rush to fire fighting as quickly as possible according to the guidance of the guidance indicators 20.

The intelligent wireless fire location notification device also includes an automatic case reporting device 50 which receives the digital codes of the other fire sensors 10 and the emergency call points 30 through the remote

control master 40 learns. When the automatic case reporting device 50 receives a radio alarm signal from a fire sensor 10, it will automatically call the police and report the case by voice.

In addition, when an emergency occurs, a person only has to press an emergency call point 30, which is immediately activated to encode the address and the situation of the emergency call point 30 and transmit it to the remote control master 40 or the other receiving slaves that have already learned the codes of the situation.

The effects of the invention will be illustrated below by describing the structure of each part in detail.

As shown in Fig. 2, each fire sensor 10 includes a central processing unit 102, a temperature and/or smoke sensor 104, a radio transmitter 106, a radio receiver 108, an address setter 110, a memory 112, and a voice device 114. The central processing unit 102 is connected to the temperature and/or smoke sensor 104, the radio transmitter 106, the radio receiver 108, the address setter 110, the memory 112, and the voice device 114. The central processing unit 102 receives the serial address codes input from the address setter 110 and stores them in the memory 112, which is generally an electrically erasable programmable read only memory (EEPROM), and receives and learns the other various digital codes sent from the remote control master 40. The sensor 104 is used to detect abnormal situations such as rapid and abnormal increase in temperature or smoke and to send a notification signal to the central unit 102. A radio alarm signal is sent from the radio transmitter 106 to inform the fire sensors of the other predetermined addresses, and the voice device 114 triggers an alarm. The other fire sensors 10 use their radio receivers 108 to receive the radio alarm signal, transmitting it to their central unit 102 to distinguish the address code of the signal and judge the fire location and situations and the most suitable escape direction, triggering alarm using their voice devices 114 and attracting some attention to inform people.

In addition, to avoid the blackout situation, each fire sensor 10 has an emergency lighting device 116 which includes a blackout detector 118, a battery 120, a bulb switch 122, a bulb 124 and a rectifier 126. The blackout detector 118, the battery 120 and the bulb switch 122 are connected to the central unit 102. The bulb 124 is connected to the bulb switch 122. The rectifier 126 is connected to an AC power input terminal 128, the blackout detector 118 and the battery 120. Normally, the electricity from the AC power input terminal 128 is transferred through the rectifier 126 and stored in the battery 120. When the obscuration detector 118 detects that an obscuration is occurring, the bulb switch is turned on by the central processing unit 102. The battery 120 provides the electricity for the bulb 124, which is used as an emergency light.

As shown in Fig. 3, the guidance display 20, which is arranged in a public place to guide people, comprises a central unit 202, a radio transmitter 204, a radio receiver 206, an address setting device 208, a memory 210, a display 212, a voice device 214, an emergency lighting device 216 and a decoder 218. The central unit 202 is connected to the radio transmitter 204, the radio receiver 206, the address setting device 208, the memory 210, the display 212, the voice device 214 and the emergency lighting device 216. The central processing unit 202 receives the serial address codes of the fire sensors 10 inputted from the address setting device 208 and stores them in the memory 210. When the radio receiver 206 receives a radio alarm signal from a fire sensor 10, the fire sensor from which the signal was sent and the best escape route are determined by processing the internal program of the central processing unit 202. The decoder 218 is used to make the display 212 display the fire location and the escape route. The voice device 214 outputs the voice previously recorded in it to inform the people in the vicinity of the escape direction or the direction for fire fighting. The structure and action of the emergency lighting device 216 are the same.

such as those of the device 116 for the emergency lighting of the fire sensor 10, and are therefore not described further.

As shown in Fig. 4, the radio emergency call station 30 includes a central unit 302, a radio transmitter 304, a radio receiver 306, a memory 308, a potential detector 310, a light emitting diode (LED) 312, a call button 314, and a battery 316. The central unit 302 is connected to the radio transmitter 304, the radio receiver 306, the memory 308, the potential detector 310, the LED 312, and the call button 314. The battery 316 provides the required electricity. The radio receiver 306 is used to receive the single serial address code of the remote control master 40 to learn the other predetermined digital codes and store them in the memory 308. The potential detector 310 is used to detect whether there is sufficient electricity in the battery 316. When an emergency occurs, a person only needs to press the call button 314. The central unit 302 in the emergency call center 30 is immediately activated to encode the address and situation of the emergency call center 30 and send them to the remote control master 40 or the other slaves that have already learned the codes of the situation, thereby calling other people to come and help. At this time, the LED 312 may be on at the same time.

As shown in Fig. 5, the automatic incident reporting device 50 includes a central unit 502, a radio transmitter 504, a radio receiver 506, a liquid crystal display (LCD), a storage device 510, a function and address setting device 512, a rechargeable battery 514, an automatic dialer 516 for fire accidents, a voice device 520 and a timer 518. When a fire accident occurs, a radio alarm signal received by the radio receiver 506 is transmitted to the central unit 502, the automatic dialer 516 is controlled by the central unit 502 to automatically call the police, and the voice device 520 will automatically report the incident with voice. In addition, when the whole intelligent wireless fire site reporting device regularly performs the self-test, the fire sensors 10 are automatically activated by test signals. The timer 518 in the automatic fall reporting device 50 is used to determine the time

for recording the time of occurrence of a fire accident when the voice device 520 reports the case to the police with voice.

All of the above slaves use the remote control master 40 to learn the settings of each other. As shown in Fig. 6, the remote control master 40 includes a central unit 402, a radio frequency (RF) transmitter 404, an RF receiver 406, a multi-function setting device 408, a display 410, a timer 412, a memory 414, a rechargeable battery 416, a potential detector 418, a lower receptacle 420 for charging, and a connection terminal 422. The central unit 402 is connected to the RF transmitter 404, the RF receiver 406, the multi-function setting device 408, the display 410, the timer 412, the memory 414, the potential detector 418, and the connection terminal 422. The central unit 402 receives the data and serial address codes input from the multi-function setting device 408, displays them on the display 410, and stores them in the memory 414. The central unit 402 also uses the RF transmitter 404 and the RF receiver 406 to set the mutual learning of the serial codes of all the slaves, such as the fire sensors 10, the routing indicators 20, the emergency call stations 30, and the automatic case reporting devices 50, so that the radio alarm signal or the digital code of the situation sent from a fire sensor 10 or an emergency call station 30 can call any slave that has learned the digital code. This enables the intelligent wireless fire site notification device to operate quickly. In addition, a cancel button is provided on the multi-function setting device 408. If the alarm is to be cancelled, it is only necessary to press the cancel button on the multi-function setting device 408 so that the central unit 402 sends a cancel signal to all slaves, such as the fire sensors 10, the routing indicators 20, the emergency call points 30 or the automatic fall reporting device 50, in order to deactivate them.

The multi-function setting device 408 of the remote control master 40 is used to set the addresses of the fire sensors 10 or the emergency call points 30. The central unit 402 adjusts the function of the timer 412 to regularly send test signals for the whole system to ensure the normal operation of each slave. The regular test signals combine

the address of each slave for testing. When the set testing time is reached each day, the remote control master 40 will send a testing signal. When the slaves, such as the fire sensors 10 and the emergency call points 30, receive the signal, they will respond using their central units. When the testing is completed, the central unit in each slave will combine the testing result and the testing status to send a complete response signal back to the remote control master 40, which records the results in the system. The rechargeable battery 416 is used to provide the required electricity for each part. The potential detector 418 is connected between the rechargeable battery 416 and the central unit 402 to detect whether there is sufficient electricity in the rechargeable battery 416. To increase the convenience of the remote control master 40, the lower charging receptacle 420 is provided for charging the rechargeable battery 416.

The connection port 422 is also provided, being connected between the remote control master 40 and a computer for real-time monitoring.

To sum up, the intelligent fire site notification device of the invention not only has learning functions and regular self-test functions, but also can inform people of the fire site and fire situation as well as the best escape direction and escape route to accurately secure their property and safety.
