Field of the Invention The present invention relates to a fire receiver, and more particularly, to a system and method for informing a manager in real time through wired or wireless communication when an abnormality occurs and a fire occurs by automatically checking a circuit abnormality in real time.

Buildings over a certain size are equipped with a fire protection system that can detect the fire and notify the person or manager in the building to minimize the damage caused by the fire.

Such a fire prevention system is installed in each part of the building, and a fire detector equipped with a sensor for detecting whether a fire has occurred is installed throughout the building, and a fire receiver that receives the signal of the fire monitor is installed in a management room. When a fire is detected, the manager alerts the fire and the location of the fire by alerting the alarm bell connected to the fire receiver and lighting the indicator on the display panel of the fire receiver itself to indicate the location of the fire. I can take it.

If such a fire protection system does not work, it is very important to check the failure of the fire protection system, because even if a fire occurs, immediate action may not be taken and serious damage may occur.

 In such a fire protection system, the fire receiver plays a pivotal role, such as supplying power to the fire alarm, alarm, and controlling alarm operation.

There may be many reasons for the failure of such a fire receiver, but one of them is the case of a disconnection or short circuit in the circuit constituting the fire receiver.

3 is a flow chart for explaining the method of the present invention.

The fire receiver circuit fault inspection system of the present invention is connected to the fire receiver and automatically checks whether the circuit of the fire receiver is short-circuited or disconnected in real time, and when it is determined that there is a fault, the circuit through a predetermined terminal such as a manager's terminal. It is characterized by the fact that an abnormality has occurred.

The fire receiver circuit abnormality inspection system of the present invention may be used in connection with an existing fire receiver in a state that is manufactured separately from the existing fire receiver, or may be included as an integral part in the manufacture of the fire receiver.

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

The fire receiver circuit fault inspection system of the present invention includes a voltage measuring unit 110, a control unit 120, a switch unit 130, a determination unit 140, an output unit 150, an information transmitting unit 160, and a command receiving unit ( 170).

The voltage measuring unit 110 measures the voltage at both ends to be measured.

The structure of the voltage measuring unit and the method of measuring the voltage are the same as those of the general voltage measuring device.

The switch unit 130 is configured to include a plurality of switches for controlling the connection between the point measuring voltage in the fire receiver and the voltage measuring unit 110.

One end of the switch provided in the switch unit 130 is connected to the point to measure the voltage in the circuit of the fire receiver, the other end is connected to the voltage measuring unit 110 when the switch is turned on the voltage of the connected circuit It is supposed to be measured.

As described above, the switch unit 130 includes a plurality of switches, and the voltage between the points connected to the two switches which are turned on is measured by the voltage measuring unit 110.

The point at which the switch of the switch unit 130 is connected to measure the voltage in the fire receiver may be arbitrarily designated by the system designer.

The main points to be measured will be the two wires connecting the fire receiver and the fire detector, the two wires connecting the fire receiver and the alarm, and the two points of the circuit in the fire receiver. It will also be possible to measure.

By dividing the circuit inside the fire receiver by module, the switch of the switch unit 130 and the circuit of the fire receiver may be connected so that the voltage is measured for each module.

The controller 120 controls on / off of each switch of the switch unit 130 periodically or by receiving a command of an administrator.

This makes it possible to measure the voltage at each point by varying the points to be measured, and it is possible to determine a circuit abnormality such as a short circuit or a disconnection using the measured voltage.

2 is a view for explaining a method of controlling each switch of the switch unit 130 in the control unit 120.

In FIG. 2, it is assumed that the left lines 201, 202, 203, and 204 are the lines to be checked on the circuit of the fire receiver.

Each line is connected to one end of the first switch 231, the second switch 232, the third switch 233, and the fourth switch 234, respectively.

The other end of each switch is connected to the voltage measuring unit 110.

When the first switch 231 and the second switch 232 are turned on by the control of the controller 120, and the third switch 233 and the fourth switch 234 are turned off, the voltage measuring unit 110 is used. ) Measures the voltage between the first line 201 and the second line 202.

In the same manner, when the second switch 232 and the third switch 233 are turned on by the control of the controller 120 and the first switch 231 and the fourth switch 234 are turned off, voltage measurement is performed. The unit 110 measures the voltage between the second line 202 and the third line 203.

In this way, the first line 201 and the third line 203, the first line 201 and the fourth line 204, the third line 203 and the fourth line 204, the second line ( Voltage between 202 and fourth line 204 may also be measured.

It is preferable that the part of the voltage to be measured and the order of the measurement are set in advance by the system designer or can be arbitrarily set by the administrator.

On the other hand, by turning off the commercial power, the control unit 120 may drive the fire receiver to the emergency power, and then measure the power at each point to be measured to measure whether the fire receiver operates normally even through the emergency power.

The control unit 120 may periodically inspect the circuit of the fire receiver or control the circuit to be inspected when an administrator or the like instructs the inspection of the fire receiver circuit. In both cases, it can be controlled to be inspected.

The determination unit 140 determines whether the circuit is abnormal using the voltage measured by the voltage measuring unit 110.

It is not necessary to receive information about where the current measured point is from the control unit when merely determining whether there is an abnormality in the entire circuit.However, in order to determine where the point is when the abnormality occurs, The information must be received.

When determining only the disconnection and the short circuit of the circuit connecting each point, even if the voltage range of the normal range at each point to be measured is not stored, only whether the voltage outside the measurement range of the voltage measuring unit 110 is measured. You can make a judgment.

However, when the voltage range of the normal range is stored and compared with this value to check whether there is an abnormality in the circuit, it is possible to make a more detailed judgment on the operation abnormality such as whether the actual supplied power is normally supplied. .

To this end, the determination unit 140 stores the voltage which is determined to be normal at each point to be measured. The controller 120 receives information regarding the current measurement point and compares it with the normal voltage of the measured point. Determine if the circuit is abnormal.

The voltage measured by the voltage measuring unit 110 may have a different required voltage level according to the measured point.

That is, the voltage at two points between the fire detector and the fire receiver, and the voltage at two points between the fire detector and the alarm bell may be judged based on the voltage provided by the fire detector to the fire detector and the alarm bell. The voltage between two points in the circuit inside the detector may vary depending on the resistance and location and capacity of other electrical components in the circuit.

For example, at two points between the fire detector and the fire receiver, if a voltage between 2 and 6 V is detected, it is determined to be normal, and if it is 0 V, it is determined as disconnection, and if the voltage is out of the measurement range, it can be determined as a short circuit. .

The output unit 150 outputs the result determined by the determination unit 140.

The output form may output a warning sound only when it is determined that an abnormality occurs, and when an abnormality occurs using a light emitting device such as an LED, a red light is emitted, and in a normal case, a green light is emitted. In addition, it may be possible to output the output, and a more precise report such as a measured point, a voltage of each measured point, and normality may be output using an LCD or the like.

In addition, the inspection details may be output using a connected printer or the like.

The place to be output through the output unit 150 will be a place where the administrator to determine the output content is located.

For example, in the case of output through a printer, the printer may be installed at a place where a fire receiver is installed, but if there is a separate management room that integrates and manages multiple buildings, it may be a printer installed in the management room.

When the determined result is output, it is preferable to output the abnormality for each point to be measured so that it is possible to know in which part the abnormality occurs when the abnormality occurs.

In this case, there is an advantage that the immediate response is possible because it can quickly and accurately know the site where the abnormality occurred.

The information transmission unit 160 transmits the result determined by the determination unit 140 to a terminal of a predetermined administrator.

At this time, it may be desirable to transmit a message to the terminal of the manager only when the determination unit 140 determines that there is an error.

The manager's terminal may be a manager's mobile phone or a landline phone, or may be a terminal dedicated to a radio or other system capable of wired or wireless communication.

If the terminal is a mobile phone, it may be able to communicate the abnormality of the circuit by text message or voice message transmission through ARS. In the case of a wired telephone or a walkie-talkie, the abnormality of the circuit may be determined by the voice message transmission using ARS. Will be able to deliver.

In addition, when a dedicated terminal is provided, information on a circuit of a fire receiver may be transmitted according to various methods such as a warning sound, a message, and a voice according to the function of the dedicated terminal.

On the other hand, the information transmission unit 160 preferably transmits information to the administrator even in the event of a fire so that the manager can quickly return to respond in the event of a fire in the absence of the administrator.

The command receiving unit 170 receives a command including an execution time for checking a circuit error of the fire receiver from an administrator or the like.

The command receiving unit 170 may be provided with a test start button or the like outside the fire receiver circuit abnormality inspection system of the present invention to directly input a manager or the like, or to instruct an inspection from a remote controller provided by the manager or the like. A wireless signal may be received, and a signal indicating an inspection may be received from a computer of an administrator connected to a system of the present invention and a wired or wireless network.

The information received through the command receiving unit 170 may be a command signal indicating an inspection immediately, or may be a command signal indicating an inspection time, an inspection period, or the like.

The administrator may instruct the inspection time, the inspection cycle, etc. so that the inspection may be executed at a predetermined time or cycle, or when necessary, the inspection may be instructed to be executed by directly or through a connection through a network.

When an inspection time, an inspection period, and the like are input through the command receiving unit 170, the information is stored in the control unit 120, and the control unit 120 determines whether a circuit of the fire receiver is abnormal at a predetermined cycle or time according to the information. It is preferable that the inspection and the inspection record are stored so that the inspection history can be confirmed later by the administrator.

3 is a flow chart illustrating a method of the present invention.

The control unit 120 determines whether or not to check the circuit abnormality of the fire receiver (301).

The inspection of the circuit abnormality of the fire receiver is performed when the preset period is reached, when the preset time is reached, or when the administrator immediately inputs the inspection command through the command receiving unit 170, so that the controller 120 Whether the test is started depends on whether or not

When it is determined that a circuit abnormality of the fire receiver should be checked, the control unit 120 controls the switch unit 130 to sequentially switch a pair of switches among the plurality of switches included in the switch unit 130 according to a set order. By turning on and off, the voltage across the point where the pair of switches are turned on is measured by the voltage measuring unit 110 (302).

If the test is to determine whether the operation using the emergency power, the control unit 120 is to turn off the commercial power and then control the switch unit 130 to be measured in the set order as described above.

The voltage measured by the voltage measuring unit 110 is transmitted to the determination unit 140 (303).

The determination unit 140 determines whether the circuit is abnormal using the voltage value measured at each point (304).

When determining only the disconnection and the short circuit of the circuit connecting each point, even if the voltage range of the normal range at each point to be measured is not stored, only whether the voltage outside the measurement range of the voltage measuring unit 110 is measured. Since it may be possible to make a judgment, information on the normal voltage range is not necessary separately, but for a more accurate judgment, a voltage that is determined to be normal at each point measured by the determination unit 140 is stored, and the stored voltage and the measured voltage It can be determined whether the circuit abnormality by comparing the as described above.

The result determined by the determination unit 140 is output by the output unit 150 (305).

The output method may be performed through a warning sound, a screen, a lighting, and the like, and the result may be output through a connected printer.

In addition, as described above, when the result of the abnormality is output, the point where the abnormality is generated may be displayed and output.

On the other hand, the information transmission unit 160 transmits the result determined by the determination unit 140 to a terminal of a predetermined administrator (306).

In this case, as described above, the message may be transmitted to the terminal of the manager only when the determination unit 140 determines that there is an error.

In addition, as described above, the terminal of the manager may be a mobile phone or a wired telephone of the manager, or a terminal dedicated to a system capable of a radio or other wired or wireless communication.
