Description

Laser smoke detector

This creation is about a laser smoke detector, which can use the principle of laser to monitor and accurately detect the smoke generated by a fire, and immediately issue an alarm to remind people to evacuate quickly, and can quickly guide people to identify the direction of escape in dense smoke, and Equipped with an automatic alarm to notify the firefighters and the homeowner about the fire.

At present, the traditional smoke detectors for detecting smoke produced during a fire mainly include photoelectric smoke detectors and ionizing smoke detectors. Photoelectric smoke detectors can change the light propagation characteristics by using the smoke generated during a fire. The principle is to use smoke to absorb and scatter light, so that the light-receiving part of the smoke detector reduces the amount of light to determine the occurrence of a fire. The ionic smoke detector uses the smoke generated during a fire to enter the smoke detector, and the smoke particles cause the ion current generated by the smoke detector to decrease, so that the smoke detector can judge the fire. Both of its smoke detectors have been widely used in indoor monitoring and detection of fires.

Of course, the smoke detectors that are traditionally used to detect smoke when a fire occurs, whether they are photoelectric smoke detectors or ionized smoke detectors, have their sensing devices located in the smoke detector body and cannot be used in a wide range. Detection, all have the shortcomings of too small detection range, for the detection of smoke in the fire and the response time is poor, especially when the indoor space is large, such as the location of the smoke detector body far from the fire point, it is convenient It is impossible to detect the occurrence of fire quickly and remind people to evacuate quickly to protect people's life safety. For example, the smoke detector can be installed to increase the detection range of the smoke detector. This will increase the cost of installing the smoke detector. cost.

In addition, because the escape exit indicator lights are mostly installed above the escape exits, but the smoke has the characteristics of rapid upward rise, so when the fire occurs, the smoke will continue to rise and block the sight of the escaped personnel. The escape personnel cannot see the exit indicator lights. Therefore, the light of the exit indicator light alone may not be able to effectively guide the personnel to quickly identify the location of the escape exit when a fire occurs, and escape the scene of the fire in time.

In view of the shortcomings caused by the above-mentioned conventional technology, this creation has developed a laser smoke detector based on the shortcomings of the conventional technology. Its main purpose is to effectively avoid the shortcomings of the above-mentioned conventional conventional smoke detectors and has deep practicality. Using the laser principle, it can monitor and accurately detect the smoke produced by the fire in a large area, and immediately send out a fire alarm to remind people to escape quickly.

This creation of a laser smoke detector, the other purpose of which is to combine with the multiple escape direction indicator lights so that the escape personnel can still clearly distinguish the escape direction when a fire occurs, so as to quickly escape from the fire scene to a safe area, and have the ability to In the event of a fire, it will automatically notify firefighters and homeowners of the fire by phone and many other functions.

In order to achieve the above and other purposes, this invention creates a laser smoke detector, which is suitable for indoor prevention and monitoring of fires, especially a smoke detector that can detect a large area and can accurately measure the smoke generated by a fire in real time. The smoke detector is provided with a laser transmitter above the room, which can emit a laser beam, which can be invisible light. In addition, a plurality of mirrors are installed around the upper part of the room to emit the laser beam. The laser beam emitted by the device can be continuously reflected around the top of the room by the plurality of mirrors, and finally form a space full of laser beams above the room, and the final point of the laser beam on the wall of the room A photoresistor is arranged at the place, and the photoresistor can receive the laser beam and transmit a signal whether the laser beam is received or not to the system controller. Since the laser beam is absorbed and scattered when encountering smoke, it is unable to concentrate the beam. Therefore, when a fire occurs, the photoresistor will be blocked by the smoke generated by the fire and cannot receive the laser beam. When the photoresistor cannot receive When the laser beam is used, it transmits a signal to the system controller, so that the system controller can use the signal to determine that a large amount of smoke is generated in the room due to a fire.

The system controller is connected to the photoresistor, the sound and light alarm and the escape direction indicator. When the system controller receives the transmission signal of the laser beam that the photoresistor cannot receive, it can be used to distinguish the indoor fire caused by fire. If a large amount of smoke is generated, it will immediately transmit a signal to the sound and light alarm and the escape direction indicator.

When the audible and visual alarm receives the signal transmitted by the system controller, it will emit flashing lights, sound effects, and voice warnings that people need to quickly escape the scene when a fire has occurred, and use automatic telephone voice methods to alert the fire brigade to the detailed address of the fire. Mobile phone text messages and automatic voice calls to notify the owner of a fire.

The escape direction indicator can be plural and set at the foot of the wall below the room. Because the smoke has the characteristics of rapid upward rise, the dense smoke will continue to rise when a fire occurs, making it impossible to see the indicator light above the escape exit when people escape. When the escape direction indicator light receives the signal transmitted by the system controller, it will emit a light source, so that people can still see the escape direction indicator in the dense smoke generated by the fire and move quickly to the escape exit in the indicated direction to escape the fire scene .

Therefore, this invention creates a laser smoke detector. With the principle of laser, it can detect the smoke from a fire in a wide range and accurately, and immediately send out an alarm to remind people to escape quickly when the fire occurs, and use automatic telephone voice method to alarm and notify The detailed address of the fire brigade and the notification to the owner of the fire by means of SMS and automatic telephone voice. In addition, people can still see the escape direction indicator in the smoke generated by the fire and quickly escape the fire scene in the indicated direction. It does have a large-scale and accurate detection and monitoring of whether a fire occurs, and immediately warns and instructs to escape when a fire occurs. Routes, automatic alarms to notify the fire brigade, and homeowners’ fire occurrence messages. In addition, in larger indoor spaces, there is no need to add a smoke detector to expand the detection range, which can reduce the installation cost of the smoke detector, thus becoming this creation The effective creator.

The following is a specific example to illustrate the implementation of this creation. Those who are familiar with this technique can easily understand the other advantages and effects of this creation from the content disclosed in this manual. This creation can also be implemented or applied by other different specific examples, and the details in this specification can also be based on different viewpoints and applications, and various modifications and changes can be made without departing from the spirit of this creation.

First of all, please refer to the first, second, and third diagrams for your reviewers. This is a laser smoke detector that you created, including:

The laser transmitter 1 is arranged above the room and can emit a laser beam 10, which can be invisible light.

A plurality of reflectors 2 are arranged around the upper part of the room. The laser beam 10 emitted by the laser transmitter 1 can be continuously reflected around the upper part of the room by the plural reflectors 2, and finally form a cloth above the room The space of the laser beam 10 is full; and the mirror 2 can also be a beam splitter, because the beam splitter can split more beams, which can achieve a more dense and accurate detection effect.

The photoresistor 3 is set at the place where the laser beam 10 is continuously reflected by a plurality of mirrors 2 and finally falls on the wall of the room. It is connected to the system controller 4, and the photoresistor 3 can transmit or receive The signal to the laser beam 10 is sent to the system controller 4. Since the laser beam 10 is absorbed and scattered when encountering smoke, it cannot concentrate the beam. Therefore, when a fire occurs, the photoresistor 3 is blocked by the smoke generated by the fire and cannot receive the laser beam 10. When the photoresistor 3 When the laser beam 10 cannot be received, a signal that the laser beam 10 cannot be received is transmitted to the system controller 4.

The system controller 4 is connected to the photoresistor 3, the sound and light alarm 5 and the escape direction indicator 6. When the system controller 4 receives the photoresistor 3 cannot receive the transmission signal of the laser beam 10, it can It is determined that a large amount of smoke is generated in the room due to a fire, and a signal is immediately transmitted to the sound and light alarm 5 and the escape direction indicator 6.

The audible and visual alarm 5 is connected to the system controller 4. When the audible and visual alarm 5 receives the transmission signal from the system controller 4, it will immediately emit a flashing light, sound effects and voice to warn people that a fire has occurred and they need to quickly escape the fire scene , And notify the fire brigade of the location of the fire by means of automatic telephone voice, and notify the homeowner of the fire by means of mobile phone text messages and automatic telephone voice.

The multiple escape direction indicator lights 6, which are connected to the system controller 4, are set at the foot of the wall below the room. Because the smoke has the characteristics of rapid upward rise, the dense smoke will continue to rise up during a fire, making people escape The escape exit indicator light 70 above escape exit 7 cannot be seen at that time. When the plurality of escape direction indicator lights 6 receive the transmission signal from the system controller 4, a light source will be emitted so that personnel can still see the escape direction indicator light 6 in the dense smoke generated by the fire and move quickly to escape in the indicated direction Exit 7 to escape the fire scene.

With the combination of the above components, this laser smoke detector can not only monitor and accurately detect the smoke generated during a fire in a large area, but also send out an alarm to remind people to escape quickly when the fire occurs. It can also use an automatic telephone Voice alarm to notify the fire brigade of the detailed address of the fire, and to notify the homeowner of the fire by SMS and automatic telephone voice. In addition, it also allows personnel to see the escape direction indicator light 6 in the thick smoke generated by the fire and quickly escape the fire scene by following the escape direction indicated by it. It does have a large-scale and accurate detection and monitoring of whether a fire occurs, and it is instantaneous when a fire occurs. There are multiple effects such as issuing warnings and indicating escape routes, automatic alarms and notifying homeowners of fire occurrence messages. In addition, if it is a larger indoor space, there is no need to add a smoke detector to expand the detection range, which can reduce the installation cost of the smoke detector. So as to become an effective creator of this creation.
