Description

A system for monitoring within-state of batteries store racks by using combined fire detectors that is possible to expand sensors}

The present invention relates to a battery storage rack internal state monitoring system using a sensor expandable composite fire detector, and more particularly, to a plurality of battery storage racks in which a plurality of batteries are stored in a stacked structure for a battery charge / discharge test or aging test. The internal state is monitored, but the smoke detection method is used to basically detect whether a fire occurs inside the battery storage rack, and auxiliary sensors that can detect fire in a method other than the smoke detection method can be added or changed in an expandable form, A sensor that can accurately detect the occurrence of a fire by using the smoke detection information of the smoke detection sensor and the detection information of an auxiliary sensor that is added or changed in an expandable form Multiple batteries are stored in a stacked structure using an expandable composite fire detector It is a technology related to a system that monitors the internal state of storage racks.

In modern society, safety accidents due to various industrial accidents are increasing along with industrial development. Among them, fire accidents require special attention because they cause many human and property damages.

In particular, fire accidents that occur at industrial sites cause large-scale fire accidents due to raw materials and chemicals used in industrial sites if the initial response fails, causing many human casualties and property damage.

As one of the industrial sites, there is a battery storage room equipped with battery storage racks in which a number of produced batteries are stored in a stacked structure for charge/discharge tests or aging tests of produced batteries.

Batteries stored in storage racks placed inside the battery storage room undergo charge/discharge tests or aging tests before shipment.

Various tests (charge/discharge test, heat resistance test, etc.) on batteries stored in storage racks are conducted on a large scale, and fire accidents may occur due to battery explosion during various tests (charge/discharge test, heat resistance test, etc.) .

Therefore, a fire detector that detects the occurrence of fire is installed inside the storage rack to monitor the internal state of the battery storage rack.

In general, there are various types of fire detectors installed to detect whether a fire occurs inside a battery storage rack.

A smoke detector that detects smoke to determine the occurrence of a fire, a temperature detector that detects the temperature to determine the occurrence of a fire, a temperature detector that detects smoke and temperature to determine the occurrence of a fire, and a flame detector that detects a flame to determine the occurrence of a fire, etc. there is

However, in the case of a fuel temperature detector that determines the occurrence of a fire by detecting smoke and temperature, the temperature sensor installed in the fuel temperature detector is installed adjacent to the detector control circuit. It can even detect heat that is too low, which can lead to the possibility of inaccurate temperature sensing.

In addition, various types of fire detectors should be installed according to the fire detection characteristics of the storage rack, which is the installation site of the fire detector. Conventional fire detectors detect fire by detecting smoke, and fire by detecting temperature. It is specialized and produced as a temperature detector that detects fire by detecting smoke and temperature, a flame detector that detects fire by detecting flame, and a flame detector that detects fire by detecting smoke and temperature. ), there is a problem in that cost is incurred when all existing installed fire detectors are changed to fire detectors having different detection characteristics.

Therefore, it is necessary to install a temperature sensor that detects the occurrence of fire by detecting the temperature at a certain distance from the detector control circuit, and even if the characteristics of the fire detector installation site (including the battery storage room where the storage rack is placed) are changed, the existing installed fire detector can be replaced with another The need to change the fire detection characteristics of the existing installed fire detector to suit the changed site (including the battery storage room where the storage rack is placed) while maintaining the existing installed fire detector without the need to install a change to a fire detector with detection characteristics this is being raised.

For example, it should be possible to change from a smoke and temperature sensing feature to a smoke and flame sensing feature, or from a smoke and temperature sensing feature to a smoke and humidity sensing feature.

Therefore, the present invention monitors the internal state of a plurality of battery storage racks in which a plurality of batteries are stored in a stacked structure for a charge / discharge test or an aging test of a battery so as to cope with the conventional problem solving or necessity, but the battery storage It basically detects whether or not there is a fire inside the rack using the smoke detection method, and auxiliary sensors that can detect fire in a method other than the smoke detection method can be added or changed in an expandable manner, and the smoke detection information and A sensor that can accurately detect the occurrence of a fire by using the detection information of an auxiliary sensor that is added or changed in an expandable way to monitor the internal state of multiple battery storage racks where multiple batteries are stored in a stacked structure using an expandable composite fire detector. I would like to suggest a technique. The following are prior art related to this.

In order to form a space, as shown in FIG. 4, it is configured to include an upper housing body 111 and a lower housing body 112 coupled to each other.

The chamber exposure port 120 is configured to be formed in the center of the upper surface of the housing body 110 (the center of the upper housing body 111) so that the smoke sensing chamber 310 can be exposed to the outside, as shown in FIG. Likewise, the smoke detection chamber 310 of the smoke detection unit 300 is exposed to the outside through the chamber exposure opening 120 .

That is, when the smoke detection unit 300 is installed in the inner space of the housing body 110, the smoke detection chamber 310 of the smoke detection unit 300 is exposed to the outside through the chamber exposure opening 120, Smoke generated by a fire is introduced into the smoke detection chamber 310 exposed to the outside.

The indicator light exposure hole 130 is formed in plurality on one side of the upper surface of the housing body 110 (one side of the upper surface of the upper housing body 111) so that the status indicator light 220 can be exposed to the outside, and the sensor is extended. When the control unit 200 is installed in the inner space of the housing body 110, as shown in FIG. 6, a plurality of status indicator lights 220 are exposed to the outside through the indicator light exposure hole 130 to monitor the sensor state. display

Meanwhile, the fire detector 2 should be able to individually set a detector ID and a detector grade.

The detector ID is sensor identification information that enables a manager to identify which detector fire is detected when a fire detection signal is transmitted to the outside, and the detector grade is grade information about the smoke detection sensitivity of the detector.

For example, if the detector level is set to type 1, a fire detection signal is generated when 5% of smoke is detected, and if it is set to type 2, a fire detection signal is generated when 15% of smoke is detected. That is, the higher the grade, the more the fire detection signal is generated even with less smoke.

Components that allow the individual setting of the sensor ID and sensor level are the sensor ID setting unit 230 and the sensor level setting unit 240 of the sensor expansion control unit 200, which will be described later, and the user uses the sensor ID setting unit 230 and the sensor By manipulating the level setting unit 240, the sensor ID and sensor level can be individually set.

As shown in FIG. 4, an operation window on the lower surface of the housing body 110 (lower surface of the lower housing body 112) so that the user can operate the sensor ID setting unit 230 and the sensor level setting unit 240. A setting unit exposure port 180 that functions is formed.

The setting unit exposure port 180 may be formed of one or two as shown in FIG. 4, and when the sensor expansion control unit 200 is installed in the inner space of the housing body 110, FIG. 6 , the sensor ID setting unit 230 and the sensor level setting unit 240 are exposed and seen through the setting unit exposure opening 180, and the user sets the sensor ID through the setting unit exposure opening 180. By manipulating the unit 230 and the sensor level setting unit 240, the sensor ID and sensor level can be individually set.

The sensor expansion control unit 200 is installed inside the sensor housing 100, displays the status of the sensor, allows the ID and grade of the sensor to be set, enables the extension of a detachable external sensor, and provides monitoring information. This is a configuration for transmitting to the sub control repeater panel (3).

Therefore, the user can expand and install external sensors (temperature detection sensor, humidity detection sensor, flame detection sensor, etc.) suitable for the sensor installation site situation through the sensor expansion control unit 200 in a detachable manner.

Specifically, the sensor extension control unit 200, as shown in FIG. 5,

A control board 210 on which the control circuit 211 is designed;

A plurality of status indicator lamps 220 installed on the control board 210 to display sensor operation status, sensor communication status, and fire detection status through lighting;

A sensor ID setting unit 230 installed on the control board 210 so that a user can set a sensor ID;

A sensor level setting unit 240 installed on the control board 210 so that a user can set a sensor level;

A power/communication terminal 250 installed on the control board 210 so that the power/communication cable connector can be connected to the control board 210;

A sensor expansion terminal 260 installed on the control board 210 so that the external sensor can be detachably coupled to the control board 210 for the extension installation of an external sensor that detects a fire in a method other than the smoke detection method It is characterized in that it includes.

The control board 210 is a kind of board-type PCB board on which the control circuit 211 is designed, and as shown in FIG. 3, the smoke detector 300 is attached and installed to the control board 210, as shown in FIG. As described above, a plurality of status indicators 220, a sensor ID setting unit 230, a sensor level setting unit 240, a power/communication terminal 250, and a sensor expansion terminal 260 are installed. A detailed description of the function of the control circuit 211 designed on the control board 210 will be described later.

As shown in FIG. 5, the status indicator light 220 is lit up to display the sensor operation status, the sensor communication status, and the fire detection status under the control of the control circuit 211, on the control board 210. As a configuration installed, when the sensor expansion control unit 200 is installed in the inner space of the detector housing 100, as shown in FIG. is exposed to indicate the state of the sensor. In particular, it is preferable to apply an LED lamp to the status indicator 220.

If a fire breaks out in an abnormal state of the detector, it can lead to a serious accident, so the manager can visually check whether the detector is powered on normally, communication with the outside is normal, and whether the fire has been detected. A plurality of status indicator lamps 220 are turned on to display the state of the detector so that it can be confirmed.

A plurality of status indicators 220 are at least a power status indicator that indicates whether or not power is normally supplied to the detector, a communication status indicator that indicates whether communication with the outside is normal, and a fire state that indicates whether or not a fire has been detected. Indicator lights may be included.

As shown in FIG. 5, the sensor ID setting unit 230 is installed on the control board 210 so that the user can set the sensor ID. When installed in the inner space, as shown in FIG. 6, it is exposed to the user through the setting unit exposure hole 180 formed in the detector housing 100, and the user can set the sensor ID through the setting unit exposure hole ( 180) to operate the sensor ID setting unit 230.

For example, a fire detector (2) installed on the 1st floor of a battery storage rack (1), which stores batteries and can perform various durability tests, has an ID of #01 and 2 of the battery storage rack (1). The fire detector (2) installed on the floor has the ID #02, and the fire detector (2) installed on the 3rd floor of the battery storage rack (1) has the ID #03, and the ID is #03 on the n floor of the battery storage rack (1). If the installed fire detector (2) needs to set the ID to #0n, the user manipulates the detector ID setting unit 230 of the fire detector (2) installed on the first floor of the battery storage rack (1) to Set the fire detector (2) to ID #01, and operate the detector ID setting part (230) of the fire detector (2) installed on the second floor of the battery storage rack (1) to set the fire detector (2) to ID # 02, set the corresponding fire detector (2) to ID #03 by manipulating the detector ID setting unit 230 of the fire detector (2) installed on the 3rd floor of the battery storage rack (1), and set the battery storage rack to ID #03. By manipulating the detector ID setting unit 230 of the fire detector 2 installed on the nth floor of (1), the corresponding detector is set to ID #0n.

At this time, the sensor ID setting unit 230 preferably applies a dip switch method as shown in FIG. 5 so that the sensor ID can be set using an on-off binary method.

The fire detector 2 should be able to initially set a detector ID and change the initially set detector ID as needed.

In particular, the reason why the initially set sensor ID can be changed as needed is that a sensor initially installed in a specific site can be installed in another site as needed. In this case, a situation may occur in which an ID, which is sensor identification information, needs to be changed according to a changed site.

The sensor level setting unit 240 is configured to be installed on the control board 210 so that the user can set the sensor level. When the sensor extension control unit 200 is installed in the inner space of the sensor housing 100, FIG. 6 As shown in, it is exposed to the user through the setting unit exposure hole 180 formed in the detector housing 100, and the user sets the sensor level through the setting unit exposure opening 180 to set the sensor level. 240 will be manipulated.

For example, a detector installed in a site requiring the installation of a first-class detector is rated as Class 1, a detector installed at a site requiring the installation of a Class 2 detector is classified as Class 2, and a detector installed at a site requiring the installation of a Class 3 detector is rated as Class 2. It is necessary to set the class of the detector to 3 types. The user operates the detector level setting unit 240 of the sensor installed in the field where the 1st type detector needs to be installed to set the level of the corresponding sensor to 1st type, and the 2nd type detector By manipulating the sensor level setting unit 240 of the sensor installed in the field requiring installation, the level of the corresponding sensor is set to 2 types, and the sensor level setting unit 240 of the sensor installed in the field requiring 3 type sensor installation By operating it, the grade of the corresponding sensor is set to 3 types.

At this time, it is preferable to apply the dip switch method as shown in FIG. 5 so that the sensor level setting unit 240 can also set the sensor level using the on-off binary method.

The detector grade is grade information about the smoke detection sensitivity of the detector. For example, if the detector grade is set to type 1, a fire detection signal is generated when 5% of smoke is detected, and if set to type 2, smoke is detected. When 15% is detected, a fire detection signal is generated. That is, the higher the grade, the more the fire detection signal is generated even with less smoke.

The fire detector 2 should be able to initially set the detector level, and change the initially set detector level as needed.

In particular, the reason why the initially set sensor class can be changed as needed is that a sensor initially installed in a specific site can be installed in another site as needed.

For example, it may be a case of moving and installing a sensor installed in a site requiring installation of a first-class detector to a site requiring installation of a second or third-type detector.

In this case, a situation may occur in which the sensor level needs to be changed according to the changed site. To this end, the sensor level initially set through the sensor level setting unit 240 can be changed and set as necessary.

The power/communication terminal 250 is a kind of connecting terminal installed on the control board 210 so that the power/communication cable connector can be connected to the control board 210, as shown in FIG. 200) is installed in the inner space of the detector housing 100, as shown in FIG. 6, it is exposed to the outside through the first terminal exposure hole 140 formed in the detector housing 100, and the cable connector for power/communication allow it to connect.

Therefore, when the power/communication cable connector is connected to the power/communication terminal 250, operation power can be supplied from the outside or detector ID information, a fire detection signal, and detection information of an external sensor can be transmitted to the outside.

The sensor extension terminal 260 is as shown in FIG. 5 so that the external sensor can be detachably coupled to the control board 210 for the extension installation of an external sensor that detects a fire in a method other than the smoke detection method. Similarly, as a kind of connecting terminal installed on the control board 210, when the sensor extension control unit 200 is installed in the inner space of the sensor housing 100, as shown in FIG. 6, the first formed on the sensor housing 100 It is exposed to the outside through the two-terminal exposure hole 150 so that an external sensor can be detachably coupled.

The external sensor coupled to the sensor extension terminal 260 may be any one of a temperature detection sensor, a humidity detection sensor, and a flame detection sensor.

Various types of fire detectors are installed according to the fire detection characteristics of the storage rack (1), which is the installation site of the fire detector. Conventional fire detectors detect fire by detecting smoke and fire by detecting temperature. temperature detectors that detect fire by detecting smoke and temperature, flame detectors that detect fire by detecting flames, etc. There was a problem of incurring cost of changing and installing all of the fire detectors having different detection characteristics.

Therefore, even if the fire detection characteristics of the storage rack (1), which is the installation site of the fire detector, are changed, the existing installed fire detector is maintained in the storage rack (1) without the need to change the installed fire detector to a fire detector having a different detection characteristic. Sensor expandability is required to change the fire detection characteristics of the existing installed fire detector to match the fire detection characteristics of the changed storage rack 1 in the state, and the configuration for this is the sensor extension terminal 260.

For example, with a fuel temperature detector installed in storage rack (1) A, which is a fire detector installation site, to detect fire by detecting smoke and temperature, the characteristics of storage rack (1) A detect fire using smoke and flame. In the case of a change in the situation where it is necessary, conventionally, the inconvenience and additional cost of having to remove the previously installed fuel temperature detector from the storage rack (1) A and newly install new detectors, smoke detectors and flame detectors, in the storage rack (1) A there was.

However, in the case of the present invention, in order to detect smoke and temperature, the temperature sensor, which is an external sensor previously coupled to the sensor extension terminal 260, is separated, and then the flame detection sensor is coupled to the sensor extension terminal 260. In this way, it is possible to change the detection characteristics of existing fire detectors (fire detection by detecting smoke and temperature) to the detection characteristics (fire detection by detecting smoke and flame) suitable for the new situation without the need to replace with a new fire detector. .

That is, the sensor extension terminal 260 allows the fire detector of the present invention to have detection sensor expandability, so that even if the characteristics of the installation site where the fire detector is installed are changed, the detection characteristics of the fire detector can be changed to suit the newly changed characteristics of the installation site. there will be

Hereinafter, specific functions of the control circuit 211 designed on the control board 210 will be described.

The control circuit 211 determines the power state, communication state, and fire detection state of the detector, and turns on a plurality of status indicators 220 to display the detected power state, communication state, and fire detection state of the detector, The detector ID information and grade information set through the detector ID setting unit 230 and the detector level setting unit 240 are stored and managed, and the received light amount information provided as smoke detection result information by the smoke detector 300 is the currently set detector level. If the amount of light received is greater than or equal to , the sensor ID information, the fire detection signal, and the detection information of the external sensor are transmitted as monitoring information to the sub control repeater panel 3, and the amount of light received provided by the smoke detector 300 as smoke detection result information When the information is less than the received light amount corresponding to the currently set sensor class, the sensor ID information and the detection information of the external sensor are transmitted to the sub control repeater panel 3 as monitoring information.

In particular, the detection information of the external sensor is temperature information when the external sensor coupled to the sensor extension terminal 260 is a temperature detection sensor, and the external sensor coupled to the sensor extension terminal 260 is a humidity detection sensor. In this case, it is characterized in that it is humidity information.

Specifically, the control circuit 211 determines the power state, communication state, and fire detection state of the detector, and displays a plurality of status indicators 220 to display the identified power state, communication state, and fire detection state of the detector. light up

That is, the control circuit 211 determines whether the power is normally supplied to the detector, and if the power is normally supplied, the power status indicator among the plurality of status indicators 220 is turned on (eg green), If the power is not normally turned on, do not turn on the power status indicator.

In addition, the detector determines whether or not communication with the outside is normally connected, and if the communication is normally connected, a communication failure state in which communication is not normally connected without turning on the communication status indicator among the plurality of status indicators 220. If not, turn on the communication status indicator (e.g. yellow).

In addition, when it is determined that a fire has occurred using the received light amount information provided by the smoke detection unit 300 as the smoke detection result information and the detection information of the external sensor, the fire status indicator light among the plurality of status indicator lamps 220 is turned on (eg : red), and if it is judged that there is no fire, the fire status indicator is not turned on.

In particular, when the control circuit 211 determines that a fire has occurred in a state in which the communication state is poor, the communication state indicator lamp and the fire state indicator light are repeatedly turned on, so that the fire detection signal is generated due to the communication failure despite the occurrence of a fire. An emergency situation that is not being transmitted to the outside informs the surroundings of a lighting alarm.

That is, when the fire detector detects that a fire has occurred, it must transmit a fire detection signal to the outside. Despite the fire, if the fire detection signal is not transmitted to the outside due to poor communication, the external In this case, the control circuit 211 repeatedly turns on the communication status indicator light and the fire status indicator light, so that the fire detection signal is not being transmitted to the outside due to poor communication despite the occurrence of a fire. The emergency situation is notified to the surroundings through repeated lighting alarms of the communication status indicator and fire status indicator.

In addition, the control circuit 211 stores and manages sensor ID information and level information set through the sensor ID setting unit 230 and the sensor level setting unit 240 .

As described above, the user sets the sensor ID and the sensor level through the sensor ID setting unit 230 and the sensor level setting unit 240. When the user sets the sensor ID and level, the control circuit 211 Stores and manages set detector ID information and grade information.

For example, when the user sets the sensor ID to #01 through the sensor ID setting unit 230 and the sensor level to 1 type through the sensor level setting unit 240, the control circuit 211 controls the set sensor ID information. and to store and manage grade information.

If the detector grade is set to 1 type, when the smoke detection unit 300 generates a fire detection signal using the received light amount information provided as smoke detection result information, a fire detection signal is generated when smoke is detected by 5%, If the detector level is set to 2, a fire detection signal is generated when 15% of smoke is detected.

In addition, the control circuit 211 controls the detector ID information, the fire detection signal, and the detection information of the external sensor when the light reception amount information provided by the smoke detection unit 300 as the smoke detection result information is greater than or equal to the light reception amount corresponding to the currently set detector class. is transmitted to the outside, and when the light received amount information provided as the smoke detection result information by the smoke detector 300 is less than the light received amount corresponding to the currently set detector class, the sensor ID information and the detection information of the external sensor are transmitted to the outside.

The smoke detector 300, which will be described later, detects smoke by a scattered light detection method, and provides light-received amount information to the control circuit 211 as smoke detection result information.

Therefore, the control circuit 211 determines that a fire has occurred if the received light amount according to the received light amount information provided by the smoke detection unit 300 as the smoke detection result information is greater than or equal to the light received amount corresponding to the currently set sensor class.

The control circuit 211 stores sensor class information set by the user and information matching the sensor class and received light amount, so that the light received amount by the light received amount information provided by the smoke detector 300 corresponds to the currently set sensor class. If it is above, it is determined that a fire has occurred, and if it is less than the received light amount corresponding to the currently set sensor level, it is determined that there is no fire.

For example, if the currently set detector class is set to type 1 and the light received amount according to the light received amount information provided by the smoke detector 300 is greater than the light received amount corresponding to the first type (the light received amount when 5% smoke is detected) It is determined that a fire has occurred, and if the light reception amount corresponding to the first type (the light reception amount when 5% smoke is detected) is less than that, it is determined that no fire has occurred.

In addition, if the currently set detector class is set to 2 types and the light reception amount according to the light reception amount information provided by the smoke detector 300 is greater than the light reception amount corresponding to 2 types (the light reception amount when 15% smoke is detected), a fire may occur. It is determined that a fire has occurred, and if the light reception amount corresponding to the second type (the light reception amount when 15% smoke is detected) is less than that, it is determined that no fire has occurred.

When it is determined that a fire has occurred, the control circuit 211 transmits the detector ID information, the fire detection signal, and the detection information of the external sensor as monitoring information to the sub control repeater panel 3, and when it is determined that there is no fire Detector ID information and external sensor detection information are transmitted to the sub control repeater panel (3) as monitoring information.

The detection information of the external sensor that the control circuit 211 transmits to the sub control repeater panel 3 as monitoring information is temperature information when the external sensor coupled to the sensor extension terminal 260 is a temperature sensor, and the sensor When the external sensor coupled to the expansion terminal 260 is a humidity sensor, it is characterized in that it is humidity information.

That is, when it is determined that there is no fire, the sensor ID information and the detection information (temperature or humidity information) of the external sensor are transmitted as monitoring information to the sub control repeater panel (3), and the temperature of the place where the fire detector is installed is transmitted. Alternatively, the manager can monitor the humidity, and if it is determined that a fire has occurred, the sub control repeater panel (3) uses the detector ID information, fire detection signal, and detection information (temperature or humidity information) of the external sensor as monitoring information. , so that the manager can monitor the temperature or humidity of the place where the fire detector is installed and at the same time recognize that a fire has occurred.

On the other hand, the control circuit 211 basically determines the occurrence of a fire using the information on the amount of light received provided by the smoke detector 300, but also by using the detection information provided by an external sensor coupled to the sensor extension terminal 260. Determine whether a fire has occurred.

That is, the control circuit 211 complexly determines whether or not a fire has occurred by using the light reception amount information provided by the smoke detection unit 300 and the detection information provided by the external sensor, and the light reception amount information provided by the smoke detection unit 300 If at least one of the detected information provided by the external sensor is information indicating the occurrence of a fire, it is determined that a fire has occurred.

Specifically, when the external sensor coupled to the sensor extension terminal 260 is a temperature sensor, the control circuit 211 controls the temperature information provided by the temperature sensor, which is an external sensor, to a preset temperature (e.g., 80 ° C) or higher, it is determined that a fire has occurred regardless of the light reception information provided by the smoke detector 300, and the detector ID information, the fire detection signal, and the temperature information, which is the detection information of the external sensor, are used as monitoring information for the sub control repeater panel Send to (3).

In addition, when the external sensor coupled to the sensor extension terminal 260 is a flame detection sensor, the control circuit 211 provides the smoke detection unit 300 when the flame detection sensor, which is an external sensor, provides flame detection information. Regardless of the amount of received light information, it is determined that a fire has occurred and the detector ID information and fire detection signal are transmitted to the sub control repeater panel 3 as monitoring information.

The smoke detection unit 300 is installed inside the detector housing 100, detects smoke in a scattered light method, and provides smoke detection result information to the sensor expansion control unit 200, as shown in FIG. , Attached to the control board 210 of the sensor extension control unit 200.

Specifically, the smoke detector 300, as shown in FIG. 7,

The smoke detector 300,

A smoke detection chamber 310 having an openable lid 311 formed on the upper side and a plurality of lattice-shaped partition walls 312 formed on the side to form a smoke inflow passage, through which smoke flows;

A light emitting element 320 installed inside the smoke detection chamber 310 and emitting light;

a light receiving sensor 330 installed inside the smoke detection chamber 310 to receive light and to provide the sensor expansion control unit 200 with an amount of light received as smoke detection result information;

A mesh filter 340 installed around the side of the smoke detection chamber 310 to prevent foreign substances other than smoke from entering through the smoke inflow passage formed on the side of the smoke detection chamber 310;

It is characterized in that it includes a light blocking wall 350 that blocks light generated from the light emitting element 320 from being directly directed to the light receiving sensor 330 .

The smoke sensing chamber 310 has an openable lid 311 formed on the upper side and a plurality of lattice-shaped partition walls 312 formed on the side to form a smoke inflow passage through which smoke flows.

A light emitting element 320, a light receiving sensor 330, and a light blocking wall 350 are installed inside the smoke sensing chamber 310 configured to include an openable lid 311 and a plurality of lattice partition walls 312.

As shown in FIGS. 7 and 8 , each of the plurality of lattice-shaped barrier ribs 312 is formed in an “L” shape to guide smoke to flow into the interior space of the smoke sensing chamber 310 .

The light receiving sensor 330 is installed inside the smoke detection chamber 310 to receive light and provide the amount of light received as smoke detection result information to the sensor expansion control unit 200. In a non-occurring state (a state in which smoke is not introduced into the smoke sensing chamber 310), the light emitted from the light emitting element 320 is not received by the light blocking wall 350 as shown in FIG. In a fire state (a state in which smoke is introduced into the smoke sensing chamber 310), as shown in B of FIG. 8, light scattered by the introduced smoke is received.

Therefore, when light is received, the light receiving sensor 330 provides the received light amount, which is the amount of light received, to the control circuit 211 of the sensor extension control unit 200 as smoke detection result information.

The mesh filter 340 is configured to be installed around the side of the smoke sensing chamber 310 so that foreign substances other than smoke are not introduced through the smoke inflow passage formed on the side of the smoke sensing chamber 310 .

Foreign substances other than smoke may flow into the smoke detection chamber 310 in a state where no fire occurs, and when light is scattered by the introduced foreign substances, the light receiving sensor 330 transmits light received amount information to the control circuit 211 It can be misunderstood that a fire has occurred by providing a mesh filter 340 on the side of the smoke detection chamber 310 to prevent this.

The light blocking wall 350 blocks light generated from the light emitting element 320 from being directly directed to the light receiving sensor 330 .

In a state in which a fire does not occur, the light emitted from the light emitting element 320 should not be received by the light receiving sensor 330. 330) provides information on the amount of light reception to the control circuit 211 so that it may be misunderstood as a fire. The blocking wall 350 is installed as shown in FIG. 8 .

On the other hand, in order to install the sensor expandable composite fire detector 2 in the battery storage rack 1, a separate installation means is required.

The sensor expandable composite fire detector (2) can be attached and installed.

In particular, the shape of the magnet 410, as shown in FIG. 9, is generally circular but has a slit groove formed on one side. The reason for forming the slit groove is that the bottom surface of the housing body 110 ( This is to prevent the setting unit exposure port 180 formed on the outer side of the lower surface of the housing body 112 from being covered by the magnet 410.

In addition, as shown in FIG. 10, the installation means 400 may be a pair of coupling protrusions 420 for attaching and installing the sensor expandable composite fire detector 2 to the battery storage rack 1. .

As shown in FIG. 10, the pair of coupling protrusions 420 protrude outside the lower surface of the housing body 110 (bottom surface of the lower housing body 112) of the detector housing 100 to store the battery. After being inserted into the installation groove formed in the rack (1), it is rotated at a certain angle so that the sensor expandable composite fire detector (2) can be attached and installed in the battery storage rack (1).

As shown in FIG. 1, the sub control repeater panel 3 collects monitoring information transmitted from the sensor expandable complex fire detectors 2 assigned to it and transmits the collected monitoring information to the integrated control repeater panel 4 that manages itself. Likewise, it is a configuration in which one or more are installed for each battery storage rack (1).

A battery production plant has a battery storage room, and a plurality of battery storage racks 1 in which batteries are stored are disposed in the battery storage room for performance tests (charge/discharge tests or aging tests, etc.) of produced batteries.

A plurality of sensor expandable composite fire detectors 2 having the above-described characteristics are installed inside the storage rack 1 so as to monitor the internal state of the storage rack disposed in the battery storage room.

At this time, the number of sensor expandable composite fire detectors 2 that can be managed by one sub control repeater panel 3 is limited. For this reason, the number of sub control repeater panels (3) to be installed inside one storage rack (1) is determined according to the number of sensor expandable complex fire detectors (2) stored inside one storage rack (1).

For example, the maximum number of sensor expandable composite fire detectors (2) that can be managed by one sub-control repeater panel (3) is 128, and the sensor expandable composite fire detectors stored inside one storage rack (1) ( If 2) is 200, two sub-control repeater panels (3) are installed inside one storage rack (1), and one sub-control repeater panel (3) is a sensor expandable composite fire detector that can be managed at maximum If the number of (2) is 256 and there are 200 sensor expandable composite fire detectors (2) stored inside one storage rack (1), then one sub-control repeater panel (3) inside one storage rack (1) is installed

Each sub-control repeater panel (3), installed one or more per battery storage rack (1), is an integrated control repeater panel ( 4) sent to

The integrated control repeater panel 4 collects monitoring information transmitted by the sub control repeater panels 3 assigned to it and transmits the collected monitoring information to the monitoring terminal 5.

At this time, the number of sub control repeater panels 3 that can be managed by one integrated control repeater panel 4 is limited. For this reason, the number of integrated control repeater panels 4 is determined according to the number of sub control repeater panels 3 installed in the storage racks 1 .

For example, the maximum number of sub control repeater panels 3 that can be managed by one integrated control repeater panel 4 is 20, and the number of sub control repeater panels 3 installed in storage racks 1 is 100. If so, five integrated control repeater panels (4) are installed.

Referring to FIG. 1 as an example, if the sub control repeater panels 3 assigned to the #1 integrated control repeater panel 4 are 20 #1-01 to #1-20 sub control repeater panels 3, # 1 The integrated control repeater panel (4) collects monitoring information transmitted by #1-01 to #1-20 sub control repeater panels (3) assigned to it and transmits it to the monitoring terminal (5).

The monitoring terminal 5 is configured to display information about the internal state of the battery storage rack 1 using monitoring information transmitted by a plurality of integrated control repeaty panels 4, and the internal state of the battery storage rack 1 Through the display of related information, the manager can quickly respond to a fire that occurred inside the storage rack (1).

Specifically, in the monitoring terminal 5, sensor installation location information is pre-stored, and the monitoring information transmitted by a plurality of integrated control repeaty panels 4 and the pre-stored sensor installation location information are used in the battery storage rack 1. Status information is displayed on the screen as shown in FIG. 11 .

In particular, the information on the internal state of the storage rack (1) displayed on the screen is temperature information for each location inside the battery storage rack (1) when the external sensor extended to the sensor expandable composite fire detector (2) is a temperature sensor. and information on whether or not a fire has occurred, and if the external sensor extended to the sensor expandable composite fire detector (2) is a humidity sensor, it includes humidity information for each location inside the battery storage rack (1) and whether or not a fire has occurred, When the external sensor extended and installed in the sensor expandable composite fire detector 2 is a flame detection sensor, it is characterized in that it includes information on whether or not a fire occurs for each location inside the battery storage rack 1.

Sensor installation location information pre-stored in the monitoring terminal 5 is information on installation locations where the sensor expandable composite fire detectors 2 are installed.

For example, the sensor installation location information is that #1-01 sensor expandable composite fire detector (2) is a fire detector stored in #1 storage rack (1) 3rd floor 1 room, and #1-05 sensor expandable composite fire detector ( 2) is a smoke detector stored in #1 storage rack (1), room 2 on the 2nd floor, and #2-03 sensor expandable composite fire detector (2) is a smoke detector stored in room 3 on the 3rd floor, #2 storage rack (1) It may be information indicating that

Therefore, the monitoring information transmitted to the monitoring terminal 5 by the plurality of integrated control repeaty panels 4 includes detector ID information, fire detection signal, and detection information of external sensors, so that the monitoring information and detector installation location information are used. When the storage rack 1, information on the internal state (whether or not a fire occurs, temperature / humidity, etc.) can be grasped. In particular, whether or not a fire has occurred can be determined intuitively by a manager using a color such as red or blue.

If the external sensor extended to the sensor expandable composite fire detector 2 is a flame detection sensor, the flame detection sensor only detects whether or not a fire occurs together with the smoke detection unit 300, but does not detect temperature/humidity, resulting in a fire. Only whether or not is displayed on the screen of the monitoring terminal (5).
