Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electronic fire detector and a receiving system using a Bluetooth i-

The present invention relates to an electronic fire detector and a receiving system using a Bluetooth i-beacon, and an electronic temperature sensor is provided as a means other than a conventional mechanical fire detector, and an alarm signal for current temperature is simultaneously output by wire and wireless An operation and an output method of an electronic fire detector for transmitting identification information (ID) of each detector and a current temperature and an alarm signal in a wireless signal, and a reception system and operation of a central control monitoring system operating by receiving the signal wirelessly ≪ / RTI >

In the case of a differential type detector, since the internal expansion pressure due to the external heat is utilized in the sealed device, when the actual fire occurs, the conventional bimetal type fire detector, There is a disadvantage in that the detection time is delayed due to the slow reaction rate,

In addition, due to the change of physical aging or chemical change due to the material and mechanical characteristics of the sensing part, the operating temperature at the time of manufacture can not be maintained accurately, and a malfunctioning detector causes a fire alarm to be issued at any time, There is also a risk of being removed. In order to prevent this, it is necessary to detect and replace only the corresponding detectors having aging, but there is a problem in that it is technically not easy to distinguish which sensor has caused aging.

In addition, existing fire detectors output alarm signals through wired terminals through the terminals attached to the detector itself, so they must be connected to each other from the detectors to the fire extinguishing system, so that the material cost of wires and wires, Labor costs for laying the wiring in the piping in the building are burdensome.

 In addition, most of the detectors are located on the ceiling, which is the highest part of the building. In order to check whether the detectors are operated during the regular inspection, The person must climb up the ladder directly to the lighter and place it on the bottom of the detector to check if the bimetal is working,

 If an abnormal fire alarm is triggered even though it is not a real fire, the suspected detectors must be manually disconnected from the circuit one by one in order to detect the fault detector. Therefore, the safety of the operator who has to ascend to the high place through inspection time and ladder There is a problem.

In order to solve this problem, an electronic temperature sensing circuit and an output circuit using a semiconductor whose measurement sensitivity does not change even in chemical or physical changes are constituted,

 In case of fire, the same output method as the conventional warm-up type and differential type detector is used to output a real alarm signal through a terminal provided in the sensor itself and at the same time, it is possible to perform individual identification for each transceiver A technique is required to transmit digital data by ID to visually confirm the current temperature or gas concentration or smoke density and alarm status around the sensors in the monitoring system of the smartphone or the central control room.

 In order to solve such a problem, the present invention sets a temperature equal to the operation temperature of the warm temperature sensor, generates an alarm signal when the temperature exceeds the set temperature, and increases the rising temperature around the sensor When the temperature rise time is detected to be faster than the prescribed time by calculating the change rate with respect to time, it is outputted as an alarm signal, which is suitable for the operation of the existing wired fire fighting system facility through the same wired output terminal as the existing differential type detector Output,

 At the same time, the Bluetooth i-beacon transmitter that is installed at the same time wirelessly sends the current sensor ambient temperature or gas concentration or smoke concentration and alarm status to the manager's smart phone and the central monitoring monitoring system, And it is aimed to be operated as a radio transmission / reception central monitoring system which does not need the wired wiring of the wireless transmission / reception.
