FIELD OF THE INVENTION [0001] The present invention relates to a fire alarm system,

The present invention relates to a disaster prevention system capable of linking with existing fire receivers, and is designed to detect faults such as crime prevention disaster prevention at an early stage or in advance to promptly inform the situation and protect them from disasters. It is easy to install and use, so it is convenient to individually manage and protect buildings or areas,

In case of fire, it is used as an input of the receiver in case of fire in consideration of the connection with the receiver, and by specifying temperature, smoke, fire, intrusion and sensors in the same area, The present invention relates to a disaster prevention system capable of being connected to a fire receiver for preventing disruption in advance by detecting a disconnection or a short circuit,

In the conventional wired and wireless real-time monitoring system, the server collects status data (temperature, smoke, humidity, flame occurrence, etc.) from the monitoring nodes, analyzes the status, determines the appropriate information level from the analyzed result, It is a server-oriented bi-directional redundant monitoring system.

There are wireless network based method and wired network based method to monitor security situation of wireless network. A method for monitoring the security situation based on a wireless network includes a method of displaying only the result of an attack detected from the security equipment of the wireless network and a method of collecting traffic information from the equipment constituting the wireless network to express statistical information.

Conventional server-oriented bi-directional surveillance system causes excessive communication amount in the surveillance network network and can easily cause a communication bottleneck. In addition, there is a possibility that the network network is easily paralyzed if the raw sensor data is simultaneously transmitted from many nodes. In addition, excessive power consumption and bandwidth increase due to excessive traffic for periodic or aperiodic unprocessed data transmission leads to an increase in the cost of constructing an unnecessary surveillance system, and therefore, there is a demand for a high-cost / high-cost design. In addition, there is a risk that the whole monitoring network will be paralyzed when an error occurs in the server due to the information processing system concentrated on the server.

Conventional fire alarm systems (fire receivers) have a problem in that it is difficult to track the location of a source by informing the whole area of an alarm occurrence.

Ubiquitous Sensor Network (USN) is a network in which a large number of nodes operate cooperatively, and the influence of a specific node on overall network performance is minimized. However, in the conventional server-oriented surveillance network, instability of the server node has a great influence on the entire network, and thus it is difficult to reflect the USN characteristic, and it is also difficult to implement USN-based application field.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a method and apparatus for detecting a fire such as crime prevention and disaster prevention in an early stage or in advance, The purpose is to manage and protect the buildings or cultural properties managed by the city, and to detect the theft and illegal movement of major objects in the area.

FIG. 3 is a block diagram of an internal configuration and an external configuration of a disaster prevention system capable of being linked to a fire receiver of the present invention

The embodiments of the present invention may be modified in various ways, and the scope of the present invention should not be interpreted as being limited by the embodiments described below.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 is a developed view showing an internal current output circuit of a disaster prevention system and a power operation of a receiver that can be connected to a fire receiver of the present invention,

In order to output a constant current from the inside of the fire alarm system, the fire alarm system generates a pulse from PWM (Pulse Width Modulation) in the internal control circuit 10, outputs the pulse, converts the pulse into light, The PWM is transmitted through the coupler 20,

A constant current output 40 is applied to the receiver 50 via the PWM smoothing circuit 30 and the feedback control of the OP AMP to convert the pulse to voltage (data).

The power of the PWM smoothing circuit 30 and the power of the constant current output 40 are obtained from the power source of the receiver 50, that is, the input terminal of the receiver,

The photo coupler 20 is a part for transmitting data by light. The transmitting part is divided into a light emitting part (LED) for receiving light and a TR (TRANSISTOR) part for receiving light to transmit electricity. Thus, the transmitter and the receiver are components that can perform the function by separating the power (isolation) by using completely separate power source.

FIG. 2 is a block diagram of an internal sensor of a fire-fighting system in connection with a fire receiver according to the present invention.

The diodes 60 are used to connect the sensors in a two-wire parallel manner that can be operated by connecting only the notifier and two wires, irrespective of the polarity of the DC power source,

In order to connect the power source, it is applied to eliminate the distinction between + and - lines,

(ID) can be set according to the site by incorporating a function of setting the current, and the position (ID) of each sensor can be set to a constant current A constant current generation circuit 80 is formed which is a constant current circuit for each type and a current consumed internally for consumption by itself.

In other words, if there is polarity, there is a time and economic loss in the process of the work because the polarity is individually checked during the installation of the sensor (detector) and there is a mistake.

The detection information of the sensors (detectors) can be confirmed by parallel connection using two strands without using a separate power source. The number of the individual sensors (detectors) is obtained by combining the CPU and the switch (SW) Can be assigned. This has the advantage that the position of the sensor (sensor) of the sensor (detector) can be grasped.

In order to realize this, the standby power of the circuit is kept constant and the current is consumed and operated.

Also, according to the number of the individual sensors (detectors, 70) by combining the switches (SW), the current consumption can be specified according to the number during sensing, and the current can be consumed constantly. Confirmation measures can save you the most time and economic loss.

In order to achieve this, in the present invention, a constant current generating circuit 80 is provided,

In the conventional case, the current consumption method of the resistance method is operated in the field.

This is due to the fact that the data of the current changes due to the fluctuation of the voltage, so that the current data fluctuation occurs due to variation of the line resistance according to the wire standard. In order to solve problems such as occurrence of current data fluctuation and inaccuracy of position confirmation due to change of resistance value due to ambient temperature, the constant current method and the standby power are kept constant.

FIG. 3 shows an internal configuration and an external configuration of a disaster prevention system that can be connected to a fire receiver according to the present invention, using the receiver shown in FIG. 1 and the two-wire type sensor shown in FIG.

Each of the two-wire type sensors 100 can be connected and identified by type and number.

3, the inside of the disaster prevention system 90 can be connected to the external receiver 110 and the two-wire type sensor 100. As shown in FIG.

In addition, by using the position sensor and the noise sensor, it is possible to prevent the intruder's movement route and the deviation of fixed objects.

Since it is operated by using a power source of the receiver because a constant current output 40 is isolated from the power source in order to associate with the receiver 50 among the functions of the disaster prevention system capable of being connected to the fire receiver of the present invention, , It can not cause problems with the receiver at a constant current output associated with the receiver.

In addition, a diode 60 is attached to the sensor so as not to distinguish the polarity of the power source, thereby realizing the convenience of construction. The constant current generation circuit 80, which is a constant current output built in the sensor, The type of sensor can be distinguished so that the position of fire and accident can be grasped.
