Abstract

The present invention provides a smart wireless fire site notifying device, which comprises a plurality of fire sensors, a plurality of route indicators, and at least a remote control master. The fire sensor gives an alarm and outputs a wireless alarming signal to other fire sensors when detecting abnormal situations. The route indicator receives the wireless alarming signal, discriminates the signal, and determines and displays the fire site and the best escape route. The remote control master sets the address serial code of each fire sensor and mutual learning of digital codes of the fire sensors and the route indicators to let them receive the wireless alarming signal simultaneously. The present invention not only has learning and regular self testing functions, it can also inform the users of the fire site and situation and the best escape direction and route to exactly ensure their properties and safety.

Claims

1. A smart wireless fire site notifying device comprising:

a plurality of fire sensors each having an address serial code, said fire sensor being used to instantly give an alarm and output a wireless alarming signal to other fire sensors when detecting an abnormal situation;

a plurality of route indicators for receiving said wireless alarming signal, discriminating from which said fire sensor is said signal emitted, and determining and displaying the best escape route; and

at least a remote control master for setting address serial codes of said fire sensors in wireless way and setting mutual learning of digital codes of said fire sensors and said route indicators so that they can simultaneously receive said wireless alarming signal.

2. The device as claimed in claim 1, wherein said fire sensor comprises a central processor connected to a sensor, a wireless emitter, a wireless receiver, an address setter, a storing memory, and a voice device, said central processor being used to receive address serial codes inputted from said address setter and store them into said storing memory, said sensor being used to detect abnormal situations and then emit out a notifying signal to said central processor to let said wireless emitter emit out said wireless alarming signal and said voice device give an alarm, other said fire sensors using said wireless receivers thereof to receive said wireless alarming signal.

3. The device as claimed in claim 2, wherein said sensor can be a temperature sensor or a smoke sensor.

4. The device as claimed in claim 1 or 2, wherein said fire sensor further has an emergency illumination device.

5. The device as claimed in claim 4, wherein said emergency illumination device comprises a blackout detector, a battery, and a light bulb switch connected to said central processor of said fire sensor, said light bulb switch being connected to a light bulb, said emergency illumination device further having a rectifier connected to an AC power input terminal and said blackout detector, said central processor turning on said light bulb switch and said battery providing the required electricity to turn on said light bulb when said blackout detector detects there is a blackout.

6. The device as claimed in claim 1, wherein said route indicator comprises a central processor connected to a wireless emitter, a wireless receiver, an address setter, a storing memory, a display, and a voice device, said central processor being used to receive address serial codes of said fire sensors inputted from said address setter and store them into said storing memory, said wireless receiver being used to receive said wireless alarming signal, which is transferred to said central processor for discriminating from which said fire sensor is said wireless alarming signal emitted, determining the best escape route and displaying it on said display, and playing it out with said voice device.

7. The device as claimed in claim 1 or 6, wherein said route indicator further has an emergency illumination device.

8. The device as claimed in claim 7, wherein said emergency illumination device comprises a blackout detector, a battery, and a light bulb switch connected to said central processor of said fire sensor, said light bulb switch being connected to an illumination lamp, said emergency illumination device further having a rectifier connected to an AC power input terminal and said blackout detector, said central processor turning on said light bulb switch and said battery providing the required electricity to turn on said illumination lamp when said blackout detector detects there is a blackout.

9. The device as claimed in claim 1, wherein said remote control master comprises a central processor connected to a radio-frequency emitter, a radio-frequency receiver, a multifunction setter, a display, a timer, and a storing memory, said central processor being used to receive data and address serial codes inputted from said multifunction setter, display them on said display, and store them into said storing memory, said radio-frequency emitter and said radio-frequency receiver being used to set mutual learning of serial codes of said fire sensors and said router indicators, said central processor matching the function of said timer to send out a test signal regularly to ensure normal operation of each device, said remote control master also having a battery for providing the required electricity for each part.

10. The device as claimed in claim 9, wherein said remote control master further has a computer connection port connected to said central processor.

11. The device as claimed in claim 1 or 9, wherein said remote control master further has a charging bottom seat for charging said battery.

12. The device as claimed in claim 1 further comprising at least an emergency caller used for transferring an address and situation signal to said preset remote control master.

13. The device as claimed in claim 1 further comprising an automatic case reporter capable of automatically telephoning the police and reporting the case with voice when receiving said wireless alarming signal.
