Generally, a large number of fire detectors are installed on the ship, and fire detectors are connected to the fire detector main system. These fire detectors are separated from the (+) (-) (auxiliary) line and connected to the main system. It is necessary to check whether the fire detector is properly installed after installing the fire detector.

FIG. 1 is a photograph of a conventional fire detector cable inspection. As shown in FIG. 1, a fire detector cable inspection method includes a two-person inspection using an electric measuring instrument and two methods of visually checking a cable connection state Are mainly used.

As shown in FIG. 2, a visual inspection is performed as shown in FIG. 2 (a) Visually check the connection status of the wiring connected to the sensor base. Wrong wiring or cable short-circuit is checked using a tester.

In addition, as shown in FIG. 2 (b), there is a risk of complaints due to the local inspection personnel approaching the position directly to the fire detector installed in the ceiling or the high-altitude area and performing the inspection using a visual inspection and a tester.

Repetitive corrective action occurs due to errors occurring in visual inspection of the connection of the fire detector.

As a prior art for solving the above problems, Korean Patent Laid-Open Publication No. 2010-59147 (published on June 4, 2010) discloses a portable circuit checker for checking a fire detector, As a checker, two lines L1 (+) and L (-) drawn out from the main panel 10 are wired as a fire detector cable, and a fire detector 20 is connected to the two lines of cables, Supply battery power to the cable connected to the fire detector.

L (-), L2 (auxiliary)) installed in the base 21 of the fire detector 20 and connected to the cable connection terminals L1 (+), L (-) and L2 L1 (+), L (-), L2 (secondary)); A first lamp 13 connected to L1 (+) and L (-) of the three terminal blocks of the circuit checker lower cover 12; A second lamp 14 connected to L1 (+) and L2 (auxiliary) among the three terminal blocks of the circuit checker lower cover 12; A buzzer 15 connected to make a buzzer sound when current flows from L (-) to L1 (+) among the three terminal blocks of the circuit checker lower cover 12; The buzzer 15 is accommodated in the lower cover 11 and the first and second lamps 13 and 14 are exposed to the outside so that the buzzer 15 is installed on the upper part of the circuit checker lower cover 11 And a circuit checker top cover (12) coupled thereto.

Since the circuit inspecting apparatus is installed in place of the existing body of the fire detector at the position to check the circuit checker as described above, the fire detector installed at a high height necessarily requires a ladder or a lift, There is a danger of falling because the work is performed, and it takes a long time to perform the inspection because the fire detector must be moved to a place where the fire detector is installed and then moved up to a high place.

The detector main body 100 contacts a terminal provided on the sensor base in a state where a fire detector installed on the ceiling is detached so as to inspect the presence or absence of an abnormality of the fire detector line to detect an abnormality.

A controller 110 is installed inside the detector body 100 so as to inspect and wirelessly detect the state of voltage, disconnection, short-circuiting, and insulation by a single PCB in the detector body 100, A contact pin 120 is provided on the detector body 100 so as to be in contact with a terminal of the detector base fixed to the ceiling.

The display unit 130 is installed on the outer surface of the detector body 100 and connected to the controller 110 so as to check the status of voltage, disconnection, short-circuit and insulation so that the display unit 130 can be transmitted by voice. A speaker 140 electrically connected to the controller 110 is installed on the detector body 100 and the speaker 110 is connected to the controller 110 through the contact pins 120, A first battery 150 is installed inside the upper portion of the detector body 100.

In addition, the detector body 100 is further connected to the controller 110 so as to detect an insulation state of the fire sensing line.

A main rod 200 and an elongated rod 300 are coupled to the detector body 100 so that a length of the main rod 200 can be extended.

The controller 110 includes a microcomputer 111, a memory unit 112, a detection unit 113, a voice transmission unit 114, and a wireless reception unit 115.

The microcomputer 111 checks the state of the fire detection line, that is, the voltage, the disconnection, the short circuit and the insulation state, compares the inspected data with predetermined data and determines the abnormal state through the display unit 130 and the speaker 140 And informs the display unit 130 of the presence or absence of the user.

The memory unit 112 inspects the state of voltage, disconnection, short circuit, and insulation, displays the program on the display unit 130, stores a program necessary for voice transmission, reads the stored program from the microcomputer 111, Voltage, disconnection, short-circuit, and insulation.

The detection unit 113 is electrically connected to the microcomputer 111 and the contact pin 120 so as to check the presence or absence of an abnormality of the fire detector line in a state where the fire detector is disconnected.

The voice transmitting unit 114 compares the state of the fire sensing line with the predetermined data in the state where the abnormality of the fire sensing line is checked in the microcomputer 111 and controls the state of the voltage, And sends the sound to the speaker 140.

The wireless receiving unit 115 receives a signal applied through the wireless transmission unit 210 installed in the main bar 200 and applies the signal to the microcomputer 111 so as to check the state of voltage, disconnection, short circuit and insulation.

The main rods 200 are connected to the detector body 100 so as to check the presence or absence of an abnormality in a fire detection line installed on the ceiling, and adjust the length and extension of the main rods 200.

The main rods 200 are formed with threaded fastening holes 201 so that the main rods 200 can be coupled with the fastening rods 103 or the connecting rods 320 to extend the length thereof.

The main rod 200 is provided with a wireless transmitter 210 for applying a signal to the controller 110 wirelessly to inspect a state of voltage, disconnection, short-circuit and insulation, And a second battery unit 230 for supplying necessary power from the wireless transmission unit 210 and the operation button 220 are installed.

The connection rod 300 is formed with a coupling hole 310 having a screw at one side so as to extend a length between the detector body 100 and the main rod 200 and a coupling protrusion 320 having a screw at the other side, .

A process for checking whether or not a fire detection line is abnormal using the fire detection line abnormality detection apparatus according to the present invention will be described.

The fire detector is detached from the detector base by using a fire detector detacher to check the presence or absence of the fire detection line. It is preferable to separate the fire detector by using a commercially available fire detector detacher (not shown) rather than using a ladder or a lift to separate the fire detector.

In a state where the fire detector is detached from the detector base, the operator screws the main rod 200 to the connecting rod 103 formed in the downward direction of the detector body 100. At this time, when the length of the main rod 200 is short, the connection rod 300 is further connected between the detector main body 100 and the main rod 200 to extend the length.

If the height of the ceiling provided with the fire detector is high, the number of the connecting rods 300 is increased so that the length can be further extended.

As described above, the detector body 100 is closely attached to the detector base separated from the fire detector in a state where the connecting rod 200 and the main rod 300 are connected to the detector body 100.

When the detector body 100 is brought into close contact with the detector base, the contact pins 120 formed on the detector body 100 are closely contacted with terminals provided on the detector base.

The operator checks the state of voltage, disconnection, short-circuit, and insulation by pressing the operation button 220 formed on the connecting rod 300 in a state where the contact pin 120 is in close contact with the terminal of the sensor base.

As shown in FIG. 4, the voltage is checked once, the double line is checked for a broken line, the triple is checked for a short circuit, and the fourth is checked for insulation, as shown in FIG.

When the operator presses the operation button 220, the wireless transmission unit 210 installed in the main bar 200 transmits a signal corresponding to the number of operations of the operation button 220 to the wireless transmission unit 210 of the detector body 100, .

The wireless receiving unit 115 receives a signal from the wireless transmitting unit 210 according to the number of operations of the operation button 220 in step S20 and applies the signal to the microcomputer 111 in step S20.

The microcomputer 111 applies a signal to the detection unit 113 to check whether there is an abnormality in the fire detection line according to the signal so as to check the state of voltage, (S30)

The detector 113 checks the voltage applied from the sensor base installed on the ceiling through the contact pin 120 and checks whether the voltage is short-circuited. The checked data is applied to the microcomputer 111, (S40). ≪ tb > < TABLE >

The voltage applied to the microcomputer 111 through the detection unit 113 indicates the degree of the voltage through the display unit 130 (S41). At this time, the current voltage is displayed as a number, and when the voltage is out of a certain range, the sound is transmitted to the speaker 140 so that the operator can confirm it.

The microcomputer 111 determines whether the short-circuit state is normal or abnormal, and displays it on the display unit 130 (S42). If the short-circuit state is a short-circuited state, the resistance becomes '0' 0 ', so that the detection unit 113 can apply a signal to the microcomputer 111 so that the microcomputer 111 can judge the signal. At the same time, the signal is displayed on the display unit 130 and the sound is transmitted through the speaker 140.

If the microcomputer 111 judges the signal applied through the detection unit 113 and the short-circuit condition is normal or abnormal, it is displayed on the display unit 130 in English (S51).

The insulated state and the shorted state are determined through a signal applied through the detection unit 113 and a normal or abnormal state of the insulation state is displayed on the display unit 130 by a signal applied from the microcomputer 111.

To inspect the insulation state, the insulation sensing line 160 provided on the detector body 100 is connected to a conductor provided on the ceiling, and the contact pin 120 installed on the detector body 100 is connected to a terminal And the ratio of the voltage and the current is determined to obtain the insulation resistance value, and the current insulation state is displayed through the display unit 130 (S52).

The microcomputer 111 displays the result on the display unit 130 and the speaker 140 detects that the microcomputer 111 is not in an abnormal state, ) So that the operator can check the insulation state of the fire detection line.

The data obtained through the detector main body 100 is stored in the memory 112 (S60), and based on the stored data, the data stored first when checking the voltage, disconnection, short-circuit, There is an advantage that the state of the current fire detection line can be accurately checked.

As described above, since the operator does not use a ladder or the like and grasps the abnormality of the fire detection line, there is an advantage that a worker can stably work, and the display unit 130 and the speaker 140 are provided on the detector body 100 It is advantageous in that the operator can visually confirm it and quickly take measures according to the relevant matters.
