Description

Ceiling sensor case with integrated sensor board {CEILING TYPE SENSOR CASE HAVING SENSOR INTERGRATION BOARD}

The present invention relates to a ceiling type sensor case with a built-in sensor integrated board, more specifically, a sensor integrated board that collects information collected from sensors for detecting a fire occurrence to provide information related to the fire to the outside. It relates to a ceiling type sensor case.

In general, a fire detector is a device that notifies the outside that a fire has occurred by detecting heat, smoke, flame, etc. generated in a fire. It is classified into thermal detector, smoke detector, flame detector and so on.

More specifically, the heat detector is a fire detector that detects heat or temperature by using a thermal sensor such as a thermistor or a thermocouple to notify the occurrence of a fire. That is, when the measured value from the heat sensor installed inside the heat detector exceeds the set value, the fire is recognized and a fire occurrence alarm is generated to the outside.

In addition, the smoke detector is a fire detector that detects smoke generated in a fire by using a correlation between the smoke concentration and an optical phenomenon such as light absorption or scattering generated when light passes through the gas containing the smoke particles. . That is, when the signal from the smoke detection sensor installed inside the smoke detector exceeds the set value, it is recognized that a fire has occurred and generates a fire occurrence alarm to the outside.

In addition, the flame detector is a fire detector for detecting infrared rays or ultraviolet rays contained in the light emitted from the flame generated by the fire. That is, when the signal from the flame detection sensor installed inside the flame detector exceeds the set value, the fire is recognized and a fire occurrence alarm is generated to the outside.

In addition to the above measurement principle, a fire detector was developed using various measurement principles and is also being developed.

Figure 1 is a schematic diagram for explaining the smoke detector measurement principle which is a kind of fire detector. Inside the smoke detector, a smoke detector light emitting element 5 serving as a light source and a smoke detector receiving sensor 4 serving as an optical sensor are installed. When air enters from the outside through a small hole or groove in the case of the smoke detector, the smoke particles 2 contained in the air scatter light emitted from the smoke detector light emitting element 5. When the scattered light is incident on the smoke detector light receiving sensor 4, the light receiving sensor generates a signal in proportion to the amount of incident light. That is, the output signal generated from the light receiving sensor has a relationship proportional to the concentration of the smoke particles.

2 shows a conventional smoke detector structure in which the smoke detector principle of FIG. 1 is specifically realized. These smoke detector outer casings 6, 8, 15 provide the function of protecting the internal components. When a fire occurs, air and smoke particles are introduced together through the air passages 7, 9, and 14 of the smoke detector outer case. At this time, the smoke particles passing through the air passage (7, 9, 14) is introduced into the measurement chamber through the dark room partitions (12, 18) inside the smoke detector.

In addition, the dark compartment partition wall is installed because strong light rays are not distinguished from the amount of light emitted from the light emitting device. At this time, when the smoke particles enter the measurement chamber through the dark room partition wall, the light emitted from the smoke detectors (10, 16) causes the scattering phenomenon by the smoke particles, the scattered scattered light smoke detectors (11, 17) Incident). Therefore, the output signal of the light receiving sensor is generated in proportion to the concentration of the smoke particles introduced into the smoke detector.

In addition, the microcontroller 13 supplies stable power to the smoke detector light emitting elements 10 and 16, amplifies the electrical signals from the light receiving sensors 11 and 17, and converts them into smoke concentrations. For example, when a fire occurs, the microcontroller detects the concentration of smoke particles and transmits a fire warning signal to the outside.

As such, smoke detectors are traditional and representative fire detectors for responding to fires that generally develop slowly due to spontaneous ignition.

3 shows a conventional flame detector structure. In FIG. 3, the protective outer case 19 provides a function of protecting an internal component. When light by the flame enters through the flame detection window 22, the flame detection sensor 21 detects infrared rays or ultraviolet rays included in the incident light and generates a change in the electrical signal. The microcontroller 23 detects an electrical signal change of the flame detection sensor 21 to determine that a fire has occurred, and transmits a fire occurrence alarm signal to the outside.

Generally, the flame detector of FIG. 3 is used to counteract an artificial fire such as arson or terrorism. Arson and terror fires are not slowly developing fires but are rapidly developing by fast burns or ultra fast burns. Fires caused by arson or terrorism generate the flames first, so the flame detector can detect fires most quickly.

However, since the outer periphery of the smoke detector is formed in a circle, it is not easy to check whether the outer periphery of the circle is slippery and completely rotated, especially when it is attached to the ceiling. There is a problem such as incompletely coupled or not. In particular, when the rotation coupling is incomplete, even if the fire detection sensor is operated, the electrical signal is not transmitted to the center, so it is not possible to know whether or not the fire occurred, so that the fire cannot be suppressed.

When the unnecessary monitoring window 230 is provided in the second housing 200, the sensor integrated board 500 installed in the second housing 200 through the monitoring window 230 is exposed to the view of the person in the building.
