Description

DISASTER CONTROL COMMUNICATION SYSTEM < RTI ID = 0.0 >

The present invention relates to an escape communication telecommunication technique for automatically detecting a disaster and informing evacuation routes to people in a disaster area, and more particularly, to a disaster communication system for detecting a disaster through a duplicated line between a fire receiver and a fire detector, The present invention relates to an automatic detection of a disaster and an evacuation control communication system that can prevent false alarms by analyzing communication traffic on the site and guide evacuation routes quickly.

In general, the term "fire-fighting equipment" refers to fire-extinguishing equipment, alarm equipment, evacuation equipment, fire-fighting water equipment, and fire-fighting equipment that operate in the event of fire in buildings. All fire- Are strictly regulated.

Recently, apartment buildings have been upgraded to high-rise buildings, and each consulate's guard room has been operated as an integrated guard room. As a result, new facilities such as R-type receiver board, smoke extraction facility, sprinkler facility, Strict management of disaster prevention systems is being implemented.

Several types of fire detectors currently in use have been developed and used depending on their functions. In particular, the detector adopted in the R type receiver has the function of address recognition in conjunction with the repeater, uses a 4-core shield cable as a 4-port type, and is used in a P-type receiver Since the detector does not have an addressable function, it is difficult to accurately grasp the location of the fire.

In the case of the conventional disaster warning system, the possibility of disaster risk is confused because it is an extremely subjective judgment judged separately by the central government or the local government's disaster prevention department. In addition, the conventional fire fighting equipment often has a malfunction. For this reason, the building manager usually turns off the power of the indicator light of the receiver and turns it on only at the time of checking. If a fire occurs, it can not be detected in advance, which can lead to a large fire.

The audio signal processing unit 147 outputs an alarm sound corresponding to the alarm condition and a voice or automatic voice signal inputted through the microphone to a broadcasting facility. The alarm driving unit 148 outputs an alarm device such as a buzzer or a beacon And the image processing unit 149 displays the operation state on a monitor connected via a cable.

The fire position detection unit 1400 normally transmits a pulse wave of a natural waveform (triangular waveform) to the common line among the sensor lines installed in the waveform generator 1401 and receives a signal via the terminal resistance Rt as a default When a fire occurs, it detects the changed signal that returns to the individual line through the sensor and analyzes the fire position. In addition, fine DC voltage is sent through the common line, and when it returns to each circuit, the temperature / humidity correction is processed to minimize and optimize the change of the pure resistance due to temperature / humidity and then divided into 5 to 10 bits The pure resistance value of the interlocking per distance is accurately detected by one bridge method. The MCU 141 repeats this resistance value detection process three times to reduce the error. If the same situation continues, the MCU 141 transmits the accident information such as the location and time of the accident to the voice and character processing device through the digital encoding process.

The accident information is displayed on the front panel display portion 146 of the monitoring control panel, and is displayed on the monitor through the image signal outlet at the lower end portion of the outer wall of the enclosure, and the alarm light is turned on and alarm or alarm is sounded through the speaker installed in the inside view.
