Transfer management and monitoring device when networking line of fire detection device is disconnected {A TRANSFER MANAGEMENT AND MONITORING DEVICE WHEN THE NETWORKING LINE OF THE SYSTEM FIRE DETECTION DEVICE IS DISCONNECTED}

The present invention relates to a switch management and monitoring device when a networking line of a fire detection device is disconnected. Specifically, when a disconnection occurs in an area of a detection line linked to a plurality of fire detection devices located in a fire detection target space, By operating the switching device connected to the detection line, the fire detection device located after the point of disconnection continues to function, and at the same time, the fire detection device and switching device are monitored in real time, so that the monitoring results meet the preset notification conditions. When met, it relates to technology that provides information based on monitoring results that meet the notice conditions to a connected fire management company.

An automatic fire detection device is a device that detects the occurrence of a fire within a building or facility and notifies the people located within the building or facility so that they can evacuate. It is a device that automatically detects the heat and smoke generated by the fire when a fire occurs. . In general, fire detection devices are installed at regular intervals within the fire detection space that is the target for detecting fire, and are installed in parallel connection on a pair of detection lines, with a disconnection in one area of the detection line. When this occurs, the fire detection device installed after the point where the disconnection occurred cannot perform its function, so there is a problem of not being able to detect fire when a fire actually occurs within buildings and facilities. Accordingly, the industry is developing various technologies to solve the above-mentioned problems.

As an example, Korean Patent No. 10-2313595 (automatic fire detection system that operates even when the detection line is disconnected) includes a technology that operates a fire detector through a separate connection means when a disconnection on the detection line is detected through a disconnection detection means. It has been disclosed.

However, in the above-described prior art, only a technology for operating a fire detector by driving a separate connection means to simply respond to a disconnection occurring in the detection line is disclosed, and a plurality of fire detection devices located in the space subject to fire detection are provided. If a disconnection occurs in one area of the interlocked detection line, the switching device connected to the detection line is operated to ensure that the fire detection device located after the disconnection point continues to function, and at the same time, the fire detection device and the switching device are operated in real time. When monitoring results meet pre-set notification conditions, there is no technology disclosed that provides information based on the monitoring results that meet the notification conditions to a connected fire management company, so there is no technology available to solve this problem. The need for is emerging.

Accordingly, the present invention is an invention derived to solve the problems of the existing technologies described above. When a disconnection occurs in an area of a detection line linked to a plurality of fire detection devices located in a fire detection target space, the switch connected to the detection line is switched. By operating the device, the fire detection device located after the point of disconnection continues to function, and at the same time, the fire detection device and switching device are monitored in real time, and if the monitoring result meets the preset notification conditions, notification is notified. By providing information based on monitoring results that meet the conditions to connected fire management companies, it not only detects fires, but also allows fire companies to identify and manage the status of fire detection devices in real time, preventing equipment malfunctions. It can prevent human casualties.

It is a configuration that detects in real time the operating status of each device and whether a disconnection occurs in the detection line. When a disconnection occurs in one area of the detection line, the disconnection point occurs after the disconnection point among the plurality of fire detection devices. a device driving control unit that operates the located fire detection devices; And a device that monitors the performance of the function of the device driving control unit in real time, and when the monitoring result satisfies preset notification conditions, transmits the monitoring abnormality information generated based on the monitoring result to the connected fire management company. It is characterized by including a monitoring management unit.

When a disconnection occurs in one area of the sensing line, the device driving control unit is connected to one area of each start line of the pair of detection lines and one area of each of the pair of end lines located opposite to the start line area. A pair of first open/close switch modules that control simultaneous open/close functions; It is located between both ends of a termination resistor connecting each of the pair of termination lines at the end of the termination line and a region of each termination line, and connects the termination resistor and each of the termination lines, A pair of second open/close switch modules that control simultaneous open/close functions; And a configuration that detects in real time whether a disconnection occurs in the detection line and simultaneously controls the functions of the first opening/closing switch module and the second opening/closing switch module, wherein the first opening/closing switch module depends on whether the detection line is disconnected. and a switch module control unit that simultaneously controls the second opening/closing switch module.

The first on/off switch module is configured to operate simultaneously with the second on/off switch module, and is operated in an open state when no disconnection occurs in the sensing line, and is closed when a disconnection occurs in the sensing line. , It is possible to connect one area of each of the start lines to one area of each of a pair of termination lines located opposite to the start line area, so that the current flowing in the first direction before being disconnected is passed in the second direction. do.

The second open/close switch module is configured to operate simultaneously with the first open/close switch module, and operates in a closed state when there is no disconnection in the detection line, and detects the sensor when a disconnection occurs in the detection line. By changing the state of the line to an open state and causing the switch module control unit to recognize that a disconnection has occurred in the sensing line, the switch module control unit closes the first open/close switch module to pass electricity in the first direction. It is possible to allow the current to pass in the second direction.

If the attribute value of the notification signal received from the device operation control unit satisfies the first notification condition among the preset notification conditions, the device monitoring management unit determines that a disconnection has occurred on the detection line and causes the device operation control unit to a first operation inspection confirmation unit that checks whether the plurality of fire detection devices are operating normally; In a state in which at least one first fire detection device that is not in operation among the plurality of fire detection devices is identified by performing the function of the first operation inspection confirmation unit, the first opening/closing switch module is performed by performing the function of the device driving control unit.

The disconnection point identification unit causes the first operation inspection confirmation unit to re-check whether the plurality of fire detection devices are operating normally, and when it is confirmed that all of the plurality of fire detection devices are operating normally, the plurality of fire detection devices are detected. There is a disconnection point on the detection line located between the second fire detection device installed before the at least one first fire detection device among the detection devices and the fire detection device corresponding to the first order of the at least one first fire detection device. It is possible to identify something as existing.

The device monitoring management unit temporarily resets the operating states of the first on/off switch module and the second on/off switch module operated by the disconnection occurring on the sensing line to the original state, and causes the termination voltage measurement unit to determine the termination voltage. And when the starting voltage measuring unit remeasures the voltage change and confirms that the remeasurement result satisfies a preset restoration value, the operating states of the first switching module and the second switching module are checked. It is possible to automatically complete the final reset by maintaining it continuously.

The inventor of the present invention uses a transfer management and monitoring device in the event of a disconnection of the networking line of the fire detection device to allow the fire detection device linked to the disconnected detection line to continuously perform the fire detection function, thereby preventing a fire that may occur in case of emergency. It can be detected.

Figure 1 is a diagram for explaining a switch management and monitoring device when a networking line of a fire detection device is disconnected according to an embodiment of the present invention.

Referring to FIG. 1, a switch management and monitoring device 100 (hereinafter, referred to as: (referred to as a fire detection device system) may include a plurality of fire detection devices (103a to 103h), a device operation control unit (107a, 107b, 111), and a device monitoring management unit (113).

According to one embodiment, the switching management and monitoring device 100 when the networking line of the fire detection device of the present invention is disconnected may have a plurality of fire detection devices 103a to 103h connected to the detection line 101 at specified intervals. there is. In relation to the above, the sensing line 101 may be connected to the device drive control unit 107a 107b, 111 and the termination resistor 109 through the terminal block 105.

In relation to the above, if a disconnection accident occurs in one area of the detection line 101, the fire detection device installed after the point where the disconnection occurred may not be supplied with electrical energy and may become inoperable. In particular, in the case of a P-type receiver, disconnection of the detection line 101 can be confirmed only by performing a continuity test when inspecting equipment for the plurality of fire detection devices (103a ~ 103h), etc., so disconnection occurs in the detection line 101. Until regular inspections of fire protection equipment are performed, equipment included in the fire detection system may operate abnormally, creating a very dangerous situation.

Accordingly, the fire detection system 100 of the present invention allows the fire detection system to operate normally even if the detection line 101 is disconnected, so that the equipment included in the fire detection system operates normally to detect the occurrence of a fire. In addition, we are launching a monitoring technology that allows fire management companies to check in real time whether a fire has occurred in the space subject to fire detection and whether there are any abnormalities in the fire detection system.

According to one embodiment, the plurality of fire detection devices 103a to 103h are located within a fire detection target space and can detect a fire that may occur within the fire detection target space.

According to one embodiment, the plurality of fire detection devices 103a to 103h may include smoke detectors and heat detectors, and may include fire detection devices of various driving types, such as constant temperature type or differential type.

According to one embodiment, the device driving control units 107a, 107b, and 111 are connected to a start line 101a, which is the start of a detection line connecting each of the plurality of fire detection devices 103a to 103h in parallel. , a configuration that detects in real time the operating status of each of the plurality of fire detection devices (103a ~ 103h) and whether a disconnection occurs in the detection line 101, and when a disconnection occurs in one area of the detection line 101, the Among the plurality of fire detection devices 103a to 103h, fire detection devices located after the disconnection point where the disconnection occurred can be operated.

In relation to the above, the device driving control units (107a, 107b, 111) include a start line (101a) where the detection line (101) that connects each of the plurality of fire detection devices (103a to 103h) in parallel begins. By being connected, the operating status of each of the plurality of fire detection devices 103a to 103h can be checked in real time.

In more detail, the device driving control unit (107a, 107b, 111) receives signals from the plurality of fire detection devices (103a ~ 103h) through two lines of the start line (101a), which starts of the detection line (101). It may have an L1 circuit capable of receiving signals from the plurality of fire detection devices 103a to 103h through two lines, an L1 circuit and a termination line 101b at the end of the detection line 101.

In relation to the above, the device driving control units 107a, 107b, 111 can check the fire signal detected by the fire detection device before the disconnection point through the L1 direction, and the fire signal detected by the fire detection device after the disconnection point (e.g., a fire signal detected after the first opening/closing switch module and the second opening/closing switch module are operated) through the L2 direction, and the plurality of fire detection devices through the fire signal detected by the fire detection device. You can check the operating status of (103a ~ 103h) in real time.

That is, the device driving control units 107a, 107b, and 111 receive separate normal signals in normal times when they do not receive the fire signal detected by the fire detection device, and through this, the plurality of fire detection devices 103a ~ 103h) operation status can be checked in real time.

According to one embodiment, the device operation control units 107a, 107b, and 111 are configured to detect in real time whether a disconnection occurs in the detection line 101, and when a disconnection occurs in one area of the detection line 101, , among the plurality of fire detection devices 103a to 103h, fire detection devices located after the disconnection point where the disconnection occurred can be operated.

In more detail, the device driving control units 107a, 107b, and 111 can detect and determine a change in voltage applied to the sensing line 101 when a disconnection occurs in one area of the sensing line 101, and the device It can be determined by measuring the voltage change or current change applied to both ends of the continuity test resistance connected in series inside the drive control unit 111.

In addition, the device drive control units 107a, 107b, and 111 can measure and determine the change in voltage at both ends of the start line 101a where the detection line 101 starts, and the voltage applied to both ends of the termination resistor 109 Whether the wire is disconnected can be determined through a change in voltage, a change in the potential difference between both ends of the termination resistor 109, or a change in the current flowing through the termination resistor 109.

In more detail, when the voltage measured at the start line 101a where the sensing line 101 starts increases beyond a certain range, the device driving control units 107a, 107b, and 111 determine the internal resistance of the sensing line 101 and The voltage applied to the sensing line 101 due to the termination resistance 109 is DC 24V, but due to the internal resistance of the device driving control units 107a, 107b, and 111 and the termination resistance 109, the sensing line 101 ), a constant current constantly flows, and this current causes a voltage drop due to the internal resistance of the device drive control units 107a, 107b, 111, and accordingly, the detection line 101 starts. A voltage of approximately 22V can be measured on line 101a.

At this time, when a disconnection occurs in the sensing line 101, the closed circuit formed by the termination resistor 109 is opened, so no current flows in the sensing line 101. In other words, since the voltage measured at the start line (101a) is measured at 24V because there is no voltage drop, it is possible to determine whether the detection line (101) is disconnected depending on whether the voltage value measured at the start line (101a) increases. there is.

According to another embodiment, the presence or absence of a disconnection can be determined by measuring the current flowing in the sensing line 101. This measures the current value flowing in the sensing line 101, and if there is no current value, it can be determined as a disconnection. . Additionally, disconnection can be measured by connecting a series resistance of a certain value to the sensing line 101 and measuring the voltage across the series resistance. If the voltage across the series resistor is 0V, no current flows, which is because a disconnection has occurred.

Accordingly, the device driving control unit (107a, 107b, 111) identifies whether the detection line 101 is disconnected through one of the above-described disconnection methods, and accordingly, the first open/close switch module 107a and the first 2 Control the open/close switch module (10b) to operate the plurality of fire detection devices (103a ~ 103h) connected to the detection circuit in which the disconnection occurred, so that the plurality of fire detection devices (103a ~ 103h) and the Each device driving control unit 111 can detect and confirm a fire that may occur within a fire detection target space.

According to one embodiment, the device monitoring management unit 113 is configured to monitor the performance of the functions of the device operation control units 107 and 111 in real time. If the monitoring result satisfies a preset known condition, the device monitoring management unit 113 Monitoring abnormality information generated based on this can be transmitted to an existing fire management company.

According to one embodiment, the linked fire management company may be a company that manages fires that may occur in the fire detection target space, and may include private fire management companies and public institutions.

Accordingly, the device monitoring management unit 113 monitors the function performance of the device operation control units 107a, 107b, and 111 in real time and provides monitoring results based on the function performance of the device operation control units 107a, 107b, and 111. Confirmation is made, and when the confirmed monitoring result satisfies the preset notification conditions, device monitoring abnormality information can be transmitted to the fire management company based on the monitoring result.

In relation to the above, the monitoring abnormality information includes the presence or absence of disconnection of the detection line 101, the disconnection point, and the status of each of the plurality of fire detection devices 103a to 103h (e.g., function being performed, inspection result, presence of failure, etc.) It may be information that it contains.

Figure 2 is a diagram for explaining a disconnection situation in a switch management and monitoring device when a networking line of a fire detection device is disconnected according to an embodiment of the present invention.

Referring to FIG. 2, a switch management and monitoring device 200 (e.g., when a networking line is disconnected) of a fire detection device implemented as a computing device including one or more processors and one or more memories storing instructions executable by the processors. The switch management and monitoring device 100 (hereinafter referred to as the fire detection device system) when the networking line of the fire detection device of FIG. 1 is disconnected includes a plurality of fire detection devices 203a to 203h and device operation control units 207a and 207b. , 211) and a device monitoring management unit 213.

According to one embodiment, when a disconnection occurs at point A on the detection line 201 of the fire detection device system 200, the device driving control units 207a, 207b, and 211 are configured to respond to the disconnection. , the first open/close switch module 207a and the second open/close switch module 207b can be controlled.

More specifically, when a disconnection occurs at point A of the sensing line 201, the device driving control units 207a, 207b, and 211 detect a voltage change, a potential difference change, or a terminating resistance between both ends 209a of the terminating resistor 209. Changes in the current value flowing through can be detected.

In relation to the above, when the device driving control unit (207a, 207b, 211) confirms that a disconnection has occurred in the detection line 201, the first opening/closing switch module (207a) and the second opening/closing switch module (207b) You can control it.

According to one embodiment, when a disconnection occurs in one area of the detection line 201, the first opening/closing switch module 207a is connected to one area of each pair of start lines 201a of the detection line 201 and the It may be a pair of end lines (201b) located opposite to the start line (201a) area and connected to each area to control simultaneous opening and closing functions.

In relation to the above, the first on/off switch module 207a may be configured to change the circuit of the sensing line 201, which is in an open circuit state when a disconnection occurs in the closed circuit state, back to a closed circuit.

In more detail, the first open/close switch module 207a is configured to operate simultaneously with the second open/close switch module 207b, and is operated in an open state when no disconnection occurs in the detection line 201. , When a disconnection occurs in the detection line 203, it is closed, and in one area of each of the start line 201a and one area of each of a pair of end lines 201b located opposite to the start line 201a area. It may be connected so that the current flowing in the first direction before being disconnected passes in the second direction.

In relation to the above, the flow of electrical energy in the fire detection system 200 before a disconnection occurs may be in a first direction (eg, the L1 direction in FIG. 1). At this time, since the first switch module 207a is in an open state, the current flowing in the L1 direction is applied to the termination resistor 209 through the second switch module 207b in a closed state. You can have a flow. That is, the second on/off switch module 207b may be configured to maintain the sensing line 201 in a closed circuit so that current flows in the L1 direction.

According to one embodiment, the second opening/closing switch module 207b includes both ends 209a of a termination resistor 209 connecting each of the pair of termination lines 201b at the end of the termination line 201b, and the It is located between one area of each of the termination lines (201b) and connects the termination resistor (209) to each of the termination lines (201b). It may be a pair of configurations that control simultaneous opening and closing functions. .

According to one embodiment, the second open/close switch module 207b is configured to operate simultaneously with the first open/close switch module 207a, and is in a closed state when no disconnection occurs in the detection line 201. When a disconnection occurs in the detection line 201, the state of the detection line is changed to an open state to cause the device operation control unit 211 to recognize that a disconnection has occurred in the detection line 201, so that the device The drive control unit 211 may be configured to close the open first switch module so that the current flowing in the first direction is passed in the second direction.

In relation to the above, by identifying the occurrence of a disconnection in the detection line 201 and controlling the second open/close switch module 207b to change the closed circuit to an open circuit, the second open/close switch module 207a A method of controlling to form the open circuit into a closed circuit that allows current to flow in the second direction will be described in FIG. 3.

That is, the present invention controls the first on/off switch module 207a and the on/off switch module 207b when a disconnection occurs in the sensing line 201 to open the state of the circuit formed by the sensing line 201. By changing the state (open circuit state) and closed state (closed circuit state), the direction of electric energy, that is, current, is changed to control the operation of the fire detection device system 200 where the disconnection occurs to detect fire. You can.

According to one embodiment, when a disconnection accident occurs in the detection line 201, the first open/close switch module 207a and the second open/close switch module 207b are shown in an operating state. The detection line 201 If a disconnection accident occurs at point A of ), the device driving control unit 211 ( can detect a situation in which the two lines of the detection line 201 have changed from a closed state to an open state, that is, a disconnection accident has occurred. there is,

According to one embodiment, when the device driving control unit 211 determines that the two lines of the sensing line 201 are in an open state, the device driving control unit 211 controls the operation of the first opening/closing switch module 207a to open the first opening/closing switch module 207a. 1 The open/close switch module (207a) can be closed. At this time, when the first on/off switch module 207a is closed, each of the start lines 201a and the end lines 201b of the detection line 201 are connected.

Accordingly, since the L2 direction in which power is applied from the device drive control unit 211 is formed in the direction of the terminal line 201b of the detection line 201, the fire detection devices 203a and 203b before point A where the disconnection occurs ) is detected by the device operation control unit 211 through the start line 201a where the detection line 201 starts, and is detected by the fire detection devices 203c to 203h after point A. Since one fire signal is detected by the device driving control units 207a, 207b, and 211 through the termination line 201b of the detection line 201 connected to the start line 201a of the detection line 201, the plurality of Fire signals detected by the fire detection devices 203a to 203h can be detected by the device driving control units 207a, 207b, and 211.

In addition, when a disconnection accident occurs on the detection line 201, the device driving control unit (207a, 207b, 211) operates the first opening/closing switch module (207a) and simultaneously operates the second opening/closing switch module (207b). It is desirable to operate the second open/close switch module 207b, which is normally closed, in an open state.

In relation to the above, when the circuit is in an open state as the second on/off switch module 207b is operated, the terminating resistor 209 is separated from the sensing line 201 and is in an open state without forming a closed circuit. , the sensing line 201 is still in an open state without being closed, just as it was right before the first switch module 207a and the second switch module 207b were activated. Accordingly, the device drive control units 207a, 207b, and 211 may determine that a disconnection has occurred in the detection line 201.

Figure 3 is a block diagram illustrating a device operation control unit of a switch management and monitoring device when a networking line of a fire detection device is disconnected according to an embodiment of the present invention.

Referring to FIG. 3, a switch management and monitoring device (e.g., in FIG. 1) when a networking line is disconnected of a fire detection device implemented as a computing device including one or more processors and one or more memories storing instructions executable by the processor. The switch management and monitoring device 100 (hereinafter referred to as the fire detection device system) when the networking line of the fire detection device is disconnected may include a device operation control unit 300.

According to one embodiment, the device operation control unit 300 is connected to a start line where a detection line that connects each of the plurality of fire detection devices in parallel begins, and detects and operates the operating status of each of the plurality of fire detection devices. It is configured to detect in real time whether a disconnection occurs in the line, so that when a disconnection occurs in one area of the detection line, fire detection devices located after the disconnection point where the disconnection occurred among the plurality of fire detection devices are operated. can do.

According to one embodiment, the device driving control unit 300 is a detailed configuration for performing the above-described functions, and includes a first opening/closing switch module 301, a second opening/closing switch module 303, and a switch module control unit 305. It can be included.

According to one embodiment, when a disconnection occurs in one region of the sensing line, the first opening/closing switch module 301 is configured to connect one region of each start line of the pair of sensing lines and the pair of sensing lines located opposite to the start line region. It may be a pair of terminal lines connected to each area to control simultaneous opening and closing functions.

In more detail, the first opening/closing switch module 301 is configured to operate simultaneously with the second opening/closing switch module 303, and is operated in an open state when there is no disconnection in the sensing line, and the sensing line is operated in an open state. When a break occurs in the line, it is closed and connected to one area of each of the start lines and one area of each of a pair of termination lines located opposite to the start line area to prevent current flowing in the first direction before the break. It may be configured to conduct electricity in two directions.

That is, when a disconnection occurs in the sensing line, the first on/off switch module 301 changes the direction of the current to the existing first direction (L1) in order to drive the fire detection device installed after the point where the disconnection occurred. direction) may be configured to change from the second direction (L2 direction).

According to one embodiment, the second on/off switch module 303 is located between both ends of a termination resistor connecting each of a pair of termination lines at the end of the termination line of the sensing line and one area of each of the termination lines. , It is a configuration that connects the termination resistor and each of the termination lines, and may be a pair of configurations that control simultaneous opening and closing functions.

In more detail, the first opening/closing switch module 303 is configured to operate simultaneously with the first opening/closing switch module 301, and operates in a closed state when no disconnection occurs in the sensing line, and the sensing line is operated in a closed state. When a disconnection occurs in the line, the state of the detection line is changed to an open state to cause the switch module control unit to recognize that a disconnection has occurred in the detection line, so that the switch module control unit closes the first open/close switch module. It may be configured so that the current flowing in the first direction is passed in the second direction.

In relation to the above, the flow of electrical energy in the fire detection device system before the disconnection occurs may be in a first direction (eg, direction L1 in FIG. 1). At this time, since the first switch module 301 is in an open state, the current flowing in the L1 direction has a flow applied to the termination resistor through the second switch module 303 in a closed state. You can.

That is, the second on/off switch module 303 may be configured to maintain the sensing line in a closed circuit so that current flows in the L1 direction before a disconnection occurs.

Accordingly, the second on/off switch module 303 is used to allow the current flowing in the L1 direction to flow in the L2 direction through the closed circuit formed by the first on/off switch module 301 when a disconnection occurs in the sensing line. It can be open.

According to one embodiment, the switch module control unit 305 detects in real time whether a disconnection occurs on the detection line and simultaneously controls the functions of the first open/close switch module 301 and the second open/close switch module 303. With a configuration that controls, the first open/close switch module and the second open/close switch module can be controlled simultaneously depending on whether the sensing line is disconnected.

In relation to the above, when a disconnection occurs in one area of the sensing line, the switch module control unit 305 controls the function of the first open/close switch module 301 to open the first open/close switch module 301. By controlling the function of the second switch module 303 and opening the closed second switch module 303, the electrical energy flowing in the L1 direction can be allowed to flow in the L2 direction.

Accordingly, the fire detection device installed after the point where the disconnection occurred is driven by electrical energy flowing in the L2 direction, so that the fire detection device system where the disconnection occurred can also perform a fire detection function.

Figure 4 is a block diagram illustrating a switch module control unit of a switch management and monitoring device when a networking line of a fire detection device is disconnected according to an embodiment of the present invention.

Referring to FIG. 4, a switch management and monitoring device (e.g., in FIG. 1) when a networking line is disconnected of a fire detection device implemented as a computing device including one or more processors and one or more memories storing instructions executable by the processor. The switch management and monitoring device 100 when the networking line of the fire detection device is disconnected (hereinafter referred to as the fire detection device system) may include a switch module control unit 400.

According to one embodiment, the switch module control unit 400 (e.g., the switch module control unit 305 in FIG. 3) detects in real time whether a disconnection occurs in the detection line and simultaneously operates the first open/close switch module and the second open/close switch module. It is a configuration that controls the functions of two open/close switch modules, and the first open/close switch module and the second open/close switch module can be controlled simultaneously depending on whether the sensing line is disconnected.

According to one embodiment, the switch module control unit 400 may include a termination voltage measurement unit 401 and a starting voltage measurement unit 403 as a detailed configuration for performing the above-described functions.

According to one embodiment, the termination voltage measuring unit 401 measures the termination voltage 401a applied to both ends (e.g., both ends 109a of FIG. 1) of the termination resistor (e.g., the termination resistor 109 of FIG. 1). is measured in real time, and when the measured terminal voltage 401a is less than or equal to a preset voltage value, it is determined that the sensing line is in a disconnected state without forming a closed circuit, and the first switching module and the second switching switch module can operate.

According to one embodiment, the termination voltage measuring unit 401 may measure the termination voltage 401a applied to both ends of the termination resistor. In relation to the above, the termination voltage measurement unit 401 may determine that a disconnection has occurred in the sensing line when the termination voltage is less than or equal to the preset voltage value.

This is because when the sensing line is disconnected, current does not pass through the terminating resistor, so the voltage applied to both ends of the terminating resistor is 0V. However, since an insignificant voltage may be measured at both ends of the termination resistor due to induced voltage and leakage current, in the present invention, when the termination voltage is measured below the preset voltage value, it is determined that a disconnection has occurred in the detection line. Let's do it.

Accordingly, the termination voltage measuring unit 401 can control the first opening/closing switch module to close the first opening/closing switch module, which was in an open state, and control the second opening/closing switch module to close the first opening/closing switch module, which was in a closed state. By opening the second on/off switch module, the current flowing in the first direction before disconnection can be allowed to conduct in the second direction after disconnection.

According to one embodiment, the starting voltage measurement unit 403 measures the voltage change of the starting line where the sensing line starts in real time, and when the measured voltage change is greater than a preset voltage change value, the sensing line starts. It is determined that the wire is in a disconnected state, and the first open/close switch module and the second open/close switch module can be operated.

According to one embodiment, the starting voltage measuring unit 403 may measure a voltage change 403a in the voltage applied to the starting line. In relation to the above, the start voltage measurement unit 403 may determine that a disconnection has occurred in the detection line when the voltage change in the voltage applied to the start line is greater than or equal to the preset voltage change value. In relation to the above, the voltage applied to the start line is normally measured at a constant voltage, but if a disconnection occurs in the sensing line, the voltage may increase.

In relation to the above, the start voltage measurement unit 403 may determine that a disconnection has occurred in the detection line when the voltage change in the voltage applied to the start line is measured to be more than a preset voltage change value.

Accordingly, the starting voltage measuring unit 403 can control the first opening/closing switch module to close the first opening/closing switch module, which was in an open state, and control the second opening/closing switch module to close the first opening/closing switch module, which was in a closed state. By opening the second on/off switch module, the current flowing in the first direction before disconnection can be allowed to conduct in the second direction after disconnection.

FIG. 5 is a block diagram illustrating a device monitoring management unit of a switch management and monitoring device when a networking line of a fire detection device is disconnected according to an embodiment of the present invention.

Referring to FIG. 5, a switch management and monitoring device (e.g., in FIG. 1) when a networking line is disconnected of a fire detection device implemented as a computing device including one or more processors and one or more memories storing instructions executable by the processor.

In relation to the above, the preset notification condition may be condition information preset to notify the linked fire management company of the status of the space subject to fire detection. In relation to the above, the first notification condition may be a standard notification condition corresponding to a state in which it is identified that a disconnection has occurred in the sensing line before the first switching module and the second switching module control the functions.

Accordingly, when the attribute value of the notice signal 501a satisfies the first notice condition 501b, the first operation inspection confirmation unit 501 determines that a disconnection has occurred in the detection line, and the device driving control unit may be requested to conduct an inspection of the plurality of fire detection devices.

In relation to the above, the device driving control unit may supply current in a first direction (L1 direction) to identify an operating fire detection device among the plurality of fire detection devices and to identify a non-operating fire detection device.

According to one embodiment, the disconnection point identification unit 503 identifies at least one first fire detection device that is not in operation among the plurality of fire detection devices by performing the function of the first operation inspection confirmation unit 501. In one state, when the first opening/closing switch module and the second opening/closing switch module are operated by performing the function of the device driving control unit, the first operation inspection confirmation unit 501 causes the plurality of fire detection devices to operate. By re-checking whether it is operating normally, the disconnection point can be identified based on the re-checking results.

According to one embodiment, the disconnection point identification unit 503 supplies current in the first direction by performing the function of the first operation inspection confirmation unit 501, thereby operating a fire detection device among a plurality of fire detection devices. In a state in which a non-operated fire detection device (e.g., at least one first fire detection device) is identified, it is confirmed that the first opening/closing switch module and the second opening/closing switch module are operated due to the performance of the function of the device driving control unit. You can.

In relation to the above, when the first on/off switch module and the second on/off switch module are operated by performing the function of the device driving control unit, when current is applied to the sensing line, the current flows in the first direction (L1 direction) ) can be energized in the second direction (L2 direction) instead of the current direction (L2 direction).

Accordingly, the disconnection point identification unit 503 may request the first operation inspection confirmation unit 501 to apply current to the detection line. At this time, the applied current is conducted in the second direction, It may be supplied to the at least one first fire detection device.

Therefore, the disconnection point identification unit 503 identifies the fire detection device that was operated when current was applied in the first direction and the fire detection device that was operated when current was applied in the second direction, and the identified fire detection device Based on the sequence, the point of disconnection occurring in the sensing line can be identified.

In more detail, the disconnection point identification unit 503 causes the first operation inspection confirmation unit 501 to re-check whether the plurality of fire detection devices are operating normally, so that all of the plurality of fire detection devices are operating normally. When operation is confirmed, a second fire detection device installed before the at least one first fire detection device among the plurality of fire detection devices (e.g., a fire detection device operated through a current applied in the L1 direction) and the at least It can be identified that a point of disconnection exists on the detection line located between the fire detection devices corresponding to the first order of one of the first fire detection devices.

According to one embodiment, when the function of the disconnection point identification unit 503 is completed, the identification information transmission unit 505 generates disconnection identification information 505a based on the identified disconnection point and connects the device to the device. It can be transmitted to a fire management company (505b).

In relation to the above, disconnection identification information 505a is information indicating a disconnection point occurring in a detection line, for example, a detection connection between a third fire detection device and a fourth fire detection device among a plurality of fire detection devices. This may be information notifying that a disconnection has occurred in one area of the line.

Accordingly, the identification information transmitting unit 505 generates the disconnection identification information 505a as described above and transmits it to the previously linked fire management company 505b, thereby sending it to the previously linked fire management company 505b. It is possible to repair the disconnection point based on the disconnection identification information 505a. That is, the disconnection identification information 505a may be one of the information included in the monitoring abnormality information. Fire detection device system According to another embodiment, the device monitoring management unit 500 has a detailed configuration for performing the above-described functions. It may include a second operation inspection confirmation unit (not shown) and a failure information provision unit (not shown).

According to another embodiment, when the attribute value of the notice signal received from the device driving control unit satisfies the second notice condition among the preset notice conditions, the second operation check confirmation unit causes a disconnection on the detection line to It is determined that the first opening/closing switch module and the second opening/closing switch module are operating, and the device driving control unit can be configured to check whether the plurality of fire detection devices are operating normally.

In relation to the above, the second known condition may be a standard known condition corresponding to a state in which the first on/off switch module and the second on/off switch module are operated due to a disconnection in the sensing line.

According to another embodiment, when the second known condition is met, the second operation check confirmation unit requests the device driving control unit to apply current in the second direction to determine whether at least one re-first fire detection device is operating. You can have it checked.

When this occurs, it is determined to have failed, and failure identification information for at least one fire detection device judged to have failed may be generated and the generated failure identification information may be transmitted to the linked fire management company.

In relation to the above, the failure information provider may confirm that at least one of the at least one first fire detection device is not operating by performing the function of the second operation inspection confirmation unit.

Accordingly, the failure information provider determines that the fire detection device that is not in operation among the at least one first fire detection device fails the inspection due to a failure, and detects a failure of the at least one fire detection device determined to have failed. Identification information can be generated.

At this time, the failure information provider is a fire detection device that was operated by a current applied in the first direction by performing the function of the first operation inspection confirmation unit 501 before performing the function of the second operation inspection confirmation unit and the second direction. In a state in which the fire detection device that was operated by the applied current is identified, the fire detection device that is not in operation can be confirmed by performing the function of the second operation inspection confirmation unit.

According to another embodiment, the failure information provider may include a fire detection device that was operated by a current applied in an identified first direction and a fire detection device that was operated by a current applied in a second direction among the plurality of fire detection devices. Can be excluded.

In relation to the above, the failure information provider excludes the fire detection device that was operated by the current applied in the identified first direction and the fire detection device that was operated by the current applied in the second direction among the plurality of fire detection devices. It is possible to confirm whether the remaining fire detection device is the same as the fire detection device that is not in operation by performing the function of the second operation check confirmation unit.

Accordingly, if the remaining fire detection device and the fire detection device that did not operate by performing the function of the second operation inspection confirmation unit are the same, the failure information provider classifies the same fire detection device as a faulty fire detection device. It can be judged as an inspection failure.

According to one embodiment, the failure information provider may generate failure identification information for the fire detection device determined to be failed. In relation to the above, the fault identification information includes the unique product number, code number (e.g., a code number that identifies the order in which it was installed on the detection line), installation location, and Information may include a unique product number and code number.

The first operation inspection confirmation unit re-checks whether the plurality of fire detection devices are operating normally, and when it is confirmed that all of the plurality of fire detection devices are operating normally, at least one of the plurality of fire detection devices Identifying that a point of disconnection exists on a detection line located between a second fire detection device installed prior to the first fire detection device and a fire detection device corresponding to the first order of the at least one first fire detection device. A switching management and monitoring device when the networking line of a fire detection device is disconnected.
In clause 7,
The device monitoring management unit,
Temporarily reset the operating states of the first on/off switch module and the second on/off switch module operated by the disconnection occurring on the sensing line to their original states, allowing the termination voltage measurement unit to measure the termination voltage and the start voltage measurement unit. When the voltage change is re-measured and it is confirmed that the re-measurement result satisfies the preset restoration value, the operation status of the first switch module and the second switch module is continuously maintained to perform a final reset. A switch management and monitoring device when a networking line of a fire detection device is disconnected, characterized in that it is automatically completed.
