Abstract

An automatic fire alarm and extinguishing device comprising fire sensitive unit (4), control unit (3), alarm device (2) and fire extinguishing device (5) is disclosed. The fire sensitive unit (4) comprises a thermometer measuring the temperature at the monitored location, a video camera taking images when temperature changes are measured by the thermometer, and a circuit transmitting the captured image to the control unit (3). In the control unit (3), the signals received from the fire sensing unit (4) are transformed into digital values, which are compared to a reference value. Upon changes of the values the control unit (3) causes the video camera to take images which are sent back to the control unit (3), where the nature of a fire is judged and messages are sent to the alarm device (2) and the extinguishing device (5).

Description

Automatic earlier alarm and extinguishing fire device

The previous art:

The common used devices of alarms and manual fire extinguishing act their own function via fire detector that, in turn, operates the extinguisher upon the alarm rising There are alarm sets operating by cutting the radiation of INFREA red giving audio signal to the computer set transmitting the indoor incidences

The problem or deficiency of the previous art:

- Manual devices have various defects and not practical

- Automatic devices are highly cost and their auto parts are not available.

The new in the invention:

Combined device of early alarm and automatic extinguisher being both linked by simple electronic circuit. The latter receives signals emerging from fire sensor. That device comprises of a thermometer measuring the temperatures of the room and connected with fixed camera indicating the temperature changes top be sent to control circuit in order to activate a mobile camera to capture what is going on inside the place.

The detailed description of the invention:

The relevant device comprises of the following:

- A thermometer

- Couple of video -camera

- Simple control circuit

- Battery

- Cylinder of kilo i - Extinguishing set

- Converter

- A set of distributing electro current to the other sets

- Ampere for measuring air pressure

- Audio-alarm

- Photo alarm

- Velvet accessing the air into the cylinder without out letting it

- External structure made of metal

1- Fire- sensing unit: comprises of a thermometer measuring the temperature of the place where the device is installed, video-camera taking the images of temperature changes measured by the thermometer, and a circuit transmitting the captured image into the control unit.

2- control unit: consists of electronic circuit receiving the signals of sensing unit to be transformed into digital values. These resulting values are to be compared to the original value that existed and registered inside the unit. Upon occurring change in the value, that is, indicating some kind of disorder, so the control unit sends an order to a mobile video camera to exit out of its small hole to photo some shots which to be sent into control unit, which, in turn, defines the nature of the fire, consequently, send message to the alarm and extinguishing sets

3- photo and audio alarming unit

4- extinguishing unit.

Then control device instruction to movable video camera in the place to take some picture of the place. These photos determine the action and what happen inside the place. These photos retransmitted to control unit which convert these picture to suitable form of signal (digital form). According to the digital form, control unit compare the values with the reference values stored in it, to determine if there is a fire or not. If there is a fire, signal will be transmitted to alarm device. Alarm device warn people of the fire. So every one can take care and leave the place. Also the fire signal is transmitted to automatic extinguishing device. Automatic extinguishing device

α consist of cylindrical air which is controlled by switch to allow air enter the cylindrical not return (air go in one direction toward the cylinder). Also, the distributor is to distribute the cylinder output to cover large area. Also, there is a pressure measurement device to control cylinder pressure. All these devices to rapidly control and extinguish the fire from more than 157 m with rotation angle about 360 degree. Alarm device can detect the fire from a distance 45 m. on the other hand, when control unit temperature reading is less than the reference value, this indicate to a safe place with any trouble (fire) in. so the alarm device is still closed, so there is no trouble happen between people in the place.

The device is used in company, hotel in the roof. So, at a fire the temperature of the thermometer is increase. Temperature sensitive device detect the changes of temperature and send these changes to control unit which transmit instruction to video camera to take some photos. These photos are retransmitted to control unit. The alarm device operates according to the control signal from control unit. Also, there is a switch used to control the electric current, which cut electric current from the device and allow it works by charged battery.

Description of the Drawing:

As in figure one the number (1) refer to automatic earlier alarm and extinguishing fire device which comprises: fire sensitive unit (4), control unit (3), alarm device (2), and extinguishing fire device (5).

Claims

Claims
1 - Automatic earlier alarm and extinguishing fire device depend on the control unit which is connected between the alarm and extinguishing device. % X- According to claim 1 , automatic earlier alarm and extinguishing fire device comprises: fire sensitive unit , control unit, alarm device, and extinguishing f^ fire device.
3 ft According to the above claims, automatic earlier alarm and extinguishing fire device comprise fire sensitive unit comprise: thermometer to measure the changes of temperature, stationary camera to , follow the changes of temperature, and transmission circuit to transmit changes of temperature to
-, control unit. f )έ According to the above claims, automatic earlier alarm and extinguishing fire device comprise control unit consist of transmitter, receiver, and modem circuit to be able to interface and control other devices. It transmits and receive control signal to other devices and compare the changes of temperature with the storage reference values. These resulting values are to be compared to the original value that existed and registered inside the unit. Upon occurring change in the value, that is, indicating some kind of disorder, so the control unit sends an order to a mobile video camera to exit out of its small hole to photo some shots which to be sent into control unit, which, in turn, defines the nature of the fire, consequently, send message to the alarm and extinguishing sets.
5- According to previous mentioned elements, the extinguishing unit consists of cylinder of kilo weight, a distributor, converter, a set of distributing the electric current to other devices, ampere instnunent, velvet for pumping and controlling the air inside the cylinder, external structure enclosing the existing devices. - the relevant device is composed as follows;
- A thermometer
- Couple of video -camera
- Simple control circuit
- Battery
- Cylinder of kilo
- Extinguishing set
- Converter
- A set of distributing electro current to the other sets
- Ampere for measuring air pressure
- Audio-alarm
- Photo alarm
- Velvet accessing the air into the cylinder without out letting it
- External structure made of metal
