Description

The utility model relates to the field of instrumentation, designed to alert and control the flow of people when evacuating from a building in the event of an emergency.

Smoke detectors are widely known, for example, operating on the principle of recording scattered radiation. Smoke detector according to A.S. USSR No. 575672, G08B 17/10; smoke detector USSR No. 1265821, G08B 17/10; scheme for detecting a decrease in the sensitivity of the photoelectric smoke detector, Japanese application No. 4-60276, No. 4-60277, G08B 17/107.

These detectors use a built-in emitting LED and a recording photodiode located at an obtuse angle to the LED. Under clean air conditions, the photodiode does not detect the emission of the LED. If smoke enters the camera, the scattered light begins to be detected by the photodiode. The analog signal from the photodiode is converted to digital and transmitted to the resolver. Upon reaching a certain threshold level of the signal, the detector generates an alarm signal.

Known light and sound sirens, for example, a device for alarm light and sound according to the patent for the invention of the Russian Federation No. 2311688, G08B 21/00.

Piezoelectric elements or dynamic loudspeakers are mainly used as sound emitters. When activated, they emit a sound of one or more frequencies, informing people about the danger. Recently, high-power LED lamps have often been used as light emitters. When activated, they perform short-term flashes, attracting the attention of people and informing them of the danger.

However, the devices described above are usually implemented as separate devices and operate within separate systems.

The closest to the proposed integrated fire detector combined with a siren, in terms of technical nature and the achieved result, is the Esser 02T / FSp IQ8Quad detector, which we took as a prototype. [Http://www.esserbyhoneywell.ru/products/802385/] . The detector contains an emitting LED that detects a photodiode, i.e. an optical pair placed in a sensitive chamber for smoke detection. In addition to the optical smoke detection function, the detector has a built-in siren to alert people about a fire.

The disadvantage of this detector, combined with a siren, is that the warning signals report only the fact of fire, but do not allow you to determine the direction to the safest escape route. Using additional sirens:

light above evacuation exits, sound and speech in rooms and along evacuation exits, also does not allow to effectively manage evacuation in conditions of smoke and panic. Particular difficulties arise when people who first enter the building (do not know the “Evacuation Plan”) or who are left without an escort (children, elderly people) are evacuated to a safe area.

Closest to the proposed warning system and dynamic evacuation control is a comprehensive emergency notification system, lighting of evacuation routes and fire-fighting equipment, as well as the organization and distribution of people flows during evacuation according to the patent for utility model of the Russian Federation No. 63092, G08B 25/08 . The system contains detectors included in the fire alarm system and light annunciators mounted on the ceiling of the room, in which LEDs are used as a light source. Additional sound and voice annunciators may be used.

The disadvantage of this system is that with smoke, the light flux from devices located on the ceiling will be blocked and the system will be unreliable. Also, it will be unreliable in bright lighting - the light from the devices will not be different in bright background lighting. It should be noted that the system is not suitable for organizing the evacuation of visually impaired people. Another problem is that when organizing an integrated system - a fire alarm, combined with a light, sound and voice warning system, you will need to install a large number of devices, which also reduces reliability.

The technical problem to which this invention is directed, is the expansion of functionality while increasing reliability and efficiency.

This problem is solved in that in an integrated fire alarm / detector containing a light emitter, a sound emitter and a smoke-sensitive element, the sound emitter is made sound-speech, providing reproduction of a multi-frequency sound signal with a ratio of the minimum and maximum frequencies of the spectrum of at least 5, and is associated as well as a light emitter with a control unit, which is connected with the information processing unit, which is connected with the information reception and transmission unit and with the smoke sensitive element.

In accordance with paragraph 2 of the formula, the integrated siren / detector is made in one housing.

In accordance with claim 3 of the formula, the information receiving unit is a radio modem.

The problem is solved in that the dynamic evacuation control system contains at least 2 complex fire alarms / detectors associated with a receiving and control device equipped with a processor that provides activation and deactivation when the sensitive element of the siren / emitter is triggered, i.e. switching on and off the light and sound emitters of the integrated fire annunciator / detector, forming a moving light path and a multi-frequency sound wave in the direction of the safe zone.

The invention is illustrated in the drawing, where:

Figure 1 - shows a block diagram of an integrated siren / detector;

Figure 2 is a block diagram of a dynamic notification system.

Figure 3-activation of sirens during system operation. The complex annunciator / detector 1, (Fig. 1) contains a light emitter 2, which is connected to a sound-voice detector 3, which is connected to a control unit 4, connected to the information processing unit 5, connected to the information reception and transmission unit bis sensitive to smoke element 7.

Thus, the light emitter 2, the control unit 4, the information processing unit 5, and the information reception and transmission unit 6 with the indicated connections represent the light annunciator; the speech and sound emitter 3 in connection with the control unit 4, the information processing unit 5, and the information reception and transmission unit 6, represent a sound annunciator, and the sensing element in connection with the information processing unit 5 and the information reception and transmission unit 6 represent a smoke detector. The annunciator / emitter is made on a modern element base.

The dynamic control system (Fig. 2) contains complex sirens 1 (from 1.1 to 1.N), the number of which is determined by the length of the evacuation zone, connected through the information reception and transmission unit 6 (Fig. 1) to the control and reception device 8 (Fig. 2).

The system operates as follows.

The sensing element 7 analyzes the smoke content in the air and transmits the information to the information processing unit 5. The information processing unit 5 is also connected to the information reception and transmission unit 6. The information on the smoke content is transmitted through the information reception and transmission unit 6 to the control panel 8. management commands are also accepted. When the command to start the notification, the information processing unit 5 generates commands to the control unit 4, which directly activates the light emitter 2 and the voice and sound detector 3.

Integrated sirens / emitters 1 are connected into a single information network with a control panel 8. made through either wired or wireless communication lines. Annunciators / detectors 1 analyze the smoke content in the air and send this information to the control panel 8.

If it becomes necessary to evacuate and notify people, for example, in an emergency or fire, the control panel 8 activates in the complex signaling devices / detectors 1 sound emitters 3 supply of multi-frequency sound and speech signals, and in light emitters 2 - their inclusion. The activation sequence is illustrated in (Figure 3): first activates the emitters in the siren / detector 1.1, then deactivates them, then activates the emitters in the complex siren / detector 1.2, then deactivates them and the emitters in the complex siren / detector 1.2 and so on to 1. N. In this case, a “running” light path and a sound wave are formed from multi-frequency sound signals in the direction of evacuation to a safe zone. Along with this, a voice alert about an emergency is formed. When the situation at the facility changes and it is necessary to redirect the flow to the desired direction, the processor of the control panel switches control of the combined siren / detector 1.

Thus, it is shown that due to the integrated implementation of the siren / detector, reliable operation with advanced functions is ensured, by providing an indication of the direction of movement of the multi-frequency sound, creating a moving light track, activation of voice messages, reliable evacuation control is provided.

As a result, the technical problem was solved by technical means and a technical result was obtained.
