Description

Recording system recording a fire detection line detection system, a detection method and a program for executing the detection method {A Detecting System of a Fire Sensing Railroad and Detecting Method}

The present invention relates to a fire detection line detection system and a recording medium in which a detection method and a program for executing the detection method are recorded. In particular, the power supply between each generation and the repeater is detected so that the flow of power between the repeater and the fire detector is properly performed. By executing the fire detection line detection system, detection method and the detection method characterized in that it is possible to easily determine whether the fire detection line abnormality by the non-expert by displaying the LED and the display of the LED disconnection or not. The present invention relates to a recording medium having recorded thereon a program.

In general, an automated fire facility refers to a facility designed to notify humans of a fire occurrence such as a fire alarm, a fire extinguishing facility and a smoke removal facility by automatically operating a fire detection sensor when a fire occurs.

In this case, the sensor is usually installed on the ceiling of a residential area or the ceiling of a building, and it is stable without change in normal times, but when smoke or heat is generated due to a fire, a minute current change is generated in the circuit of the sensor so that a fire occurs by conducting a line. Be aware of this.

Fire management system can be divided into P (Proprietary) type system and R (Recode) type system according to the form of signal transmission between detector and receiver. The P-type system wires between the receiver and the detector for each line, and the R-type system uses a transmission technique such as a time division method to transmit signals of multiple lines to the same signal line. R-type system is economical because there are fewer lines than P-type system, it is possible to lengthen the length of the line, it is easy to expand or relocate, display the fire generating mechanism numerically, and transmit signal clearly. . Such an R-type system has a configuration in which a detector and a receiver are connected to each other through a repeater.

On the other hand, the repeater transmits the detection signal transmitted from the various detectors to the receiver and not only controls the various fire-fighting facilities according to the command of the receiver, but also has a function to check the self abnormality or disconnection of the detector and recall the abnormal signal. It also plays a role of sending to the receiver.

However, there has been a problem that it is difficult to check whether the repeater operates correctly in the state of connecting various sensors through the terminal.

A first switching transistor Q1 having a common terminal coupled thereto, a waveform shaping unit U1A connected to an output terminal of the first switching transistor Q1 to shape a waveform, and an output of the waveform shaping unit U1A. A second switching transistor Q2 for switching the output by connecting to the base terminal and a relay K1 for switching a 22V power supply according to the output of the second switching transistor Q2.

Looking at the operation of the normal operation check circuit 210 below, first adjusts 22V voltage to pass only the 16V while passing through the zener diode (ZD1), in which the current flows in the reverse direction by the reverse voltage prevention diode (D1) Is prevented. The voltage of 16V passes through the first switching transistor Q1, the waveform shaping unit U1A, and the second switching transistor Q2 to the output port UA1 and to the controller 400 through the output port UA1. When approved, it determines whether it works normally. At this time, if the flow of power is maintained below 16V, the flow of power does not occur in the zener diode ZD1, and thus the power generated through the output port UA1 does not exist. Accordingly, the control unit 400 repeats the repeater 20. It can be seen that does not operate normally. In addition, the non-operation state is output to the outside through the LED display means 500. On the other hand, if the flow of power over 16V is maintained, normal power flow is induced through the zener diode ZD1, and when applied to the control unit 400 through the output port UA1, the control unit 400 normally powers the repeater 20. Confirm that this is induced and outputs it to the outside through the LED display means (500).

A fourth switching transistor Q4 for switching the output by connecting the output to the base end and a relay K2 for switching the power of 16V according to the output of the fourth switching transistor Q4.

Referring to the operation of the low voltage detection circuit unit 220 below, the low voltage detection circuit unit 220 is applied to the control unit 400 through the output port UA2 when a power of 12V or more is applied to check this. As a result, only a voltage of 12 V is induced while passing through the zener diode ZD2. At this time, when the power is induced below 12V, there is no voltage value output through the zener diode ZD2, and there is no power output to the controller 400 through the fourth switching transistor Q4. It can be seen that the power is induced in the low voltage state.

The detector operation detection circuit 230,

Referring to the operation of the detector operation detection circuit unit 230 below, the detector operation detection circuit unit 230 is designed to be powered through the zener diode (ZD3) when more than 5V of power is induced, if the input power is If the voltage is less than 5V, the power output through the zener diode ZD3 and the fifth switching transistor Q5 does not exist, so that the control unit 400 knows that there is no power provided to the repeater 20, and the LED display means Output to the outside through 500.

It includes an output port (RA3) for outputting whether is applied to the outside.

The positive line short circuit detector 240 detects whether the positive line of the circuit is shorted. If the circuit is shorted, the photo coupler U2 is operated to output a signal to the controller 400 through the output port RA3. Is applied, and accordingly, the controller 400 may recognize that the plus line is short-circuited, and outputs the result to the outside through the LED display means 500.

The negative line line short circuit detection unit 250,

5V inductive resistor (R19), photo coupler (U3), the negative short-circuit detection sensor (JP1) electrically connected to the lower end of the photo coupler (U3), and the output terminal of the photo coupler (U3) is installed in the circuit It includes an output port (SUB) for outputting whether 5V is applied to the outside.

The negative line short circuit detector 250 detects whether a negative line of the circuit is shorted. When a short circuit is detected by the negative short sensor JP1, a signal is transmitted to the controller 400 through the photo coupler U3. The controller 400 recognizes that the negative line is short-circuited, and thus notifies the negative line that the negative line is short-circuited through the LED display means 500.

For example, when the green lamp GR of the LED lamp sets LD1 and LD2 is normal, In case of low voltage, the red lamp RD of LED lamp No.2 LD3 and LD4 is turned on, and the red lamp RD of LED lamp No.1 LD1 and LF2 is turned on during detector operation.
