Description

  The present invention relates to a fire extinguishing equipment control system, and more particularly, to a fire extinguishing equipment control system linked to the operation of a fire detector.

  Conventionally, a pre-acting sprinkler fire extinguishing system is connected to a pre-acting valve that opens in conjunction with a fire detector, a sprinkler head connected to the pre-acting valve secondary side pipe, and a pre-acting valve primary side pipe. When a fire detector fires, or when the fire detector fires and the sprinkler head that is normally closed is opened due to the heat of the fire Controls the open pre-actuating valve to be closed, and the fire-extinguishing pump controller that detects that the pressure of the pre-acting valve primary side pipe has changed due to water flow to the secondary pipe of the pre-acting valve is Fire water is sprinkled from the sprinkler head that is opened by the heat of the fire, which is connected to the secondary piping of the pre-actuated valve that is opened by pumping fire-extinguishing water from the fire-extinguishing water tank by starting the water-feeding device. I do.

  For this reason, as long as the fire detector does not generate a fire, even if an accident that damages the sprinkler head occurs, fire-extinguishing water is not unnecessarily discharged from the damaged sprinkler head.

  Such pre-actuated sprinkler fire extinguishing equipment divides the protection target into a plurality of adjacent protection sections when the protection target is a large area, etc. Side piping and fire detectors corresponding to the protective compartment may be provided. In such a case, the fire can be effectively extinguished if the fire zone where the fire detector has reported the fire matches the protective zone of the corresponding fire extinguishing equipment.

JP-A-56-152661

  However, depending on the location of the fire, the structure of the building, the fire properties, the detection principle of the fire detector, etc., the fire compartment where the fire detector fires may not match the protective compartment to be extinguished.

  For example, if the location of the fire is near the boundary of the protective compartment, both fire detectors in the adjacent compartment may fire. If the fire detector detects heat or smoke, the heat or smoke may flow to the fire detector in the farthest area from the location of the fire due to the direction of convection due to the heat of the fire or the airflow from the air conditioner. There is also a risk of fire.

  At this time, if control is performed so that only the pre-actuation valve of the section where the fire is reported is opened, even if the sprinkler head is opened by the heat of the fire, water will sprinkle from the far side of the fire and the fire will occur. There is a possibility that water cannot be sprayed to the place.

  As described above, when the location of the fire is near the boundary of the protection zone, the fire detectors in the adjacent zone may both fire simultaneously. At this time, if the pre-actuated valves of a plurality of adjacent protective zones are opened at the same time, depending on the water supply capacity of the pressurized water supply device, the pipe volume, etc. It takes time until fire-extinguishing water reaches the opened sprinkler head, or it takes time to reach the specified water discharge pressure, and it takes time to reach the specified fire-extinguishing action. There is a possibility that the start is delayed.

  Similarly, if the location of the fire is near the boundary of the protected area and the fire detector detects radiation from a fire source flame, such as infrared or ultraviolet light, in order to eliminate the blind spot of fire monitoring Because it is arranged so that the monitoring range of multiple adjacent fire detectors overlaps, the fire detector farther away from the location of the fire will fire first, or multiple fire detectors will fire simultaneously In addition, there may be cases where fire detectors in areas other than the place where the fire occurred are reported due to reflections from building walls, pillars, fixtures, and other installations. There is a risk that water will sprinkle from a distance, or it will take time to reach the specified fire extinguishing operation, and the effective start of water sprinkling to the place where the fire has occurred may be delayed.

  In view of the above circumstances, the present invention can be used even when it is difficult to specify a fire extinguishing area between a plurality of protective compartments, or when it is difficult to specify a fire extinguishing area such as when a fire has occurred near the boundary of a plurality of protective compartments. An object of the present invention is to obtain a control system and control method for a fire extinguishing facility that can extinguish a fire quickly or can perform effective fire extinguishing while preventing the spread of fire.

  According to the present invention, fire extinguishing means and fire detection means are arranged corresponding to each section, and control of fire extinguishing equipment that controls to activate the corresponding fire extinguishing means in conjunction with a fire signal from the fire detection means In the system, a fire signal receiving means for receiving the fire signal to identify a fire section, an interlock control means for determining a fire extinguishing section to be activated corresponding to the fire section, and a fire extinguishing based on the determination of the interlock control means An activation signal output means for outputting an activation signal to a fire extinguishing means for a section; an extinguishing signal receiving means for receiving an extinguishing signal output by the extinguishing means during extinguishing; and a specified fire extinguishing operation after the extinguishing means is started The waiting time setting means for registering and storing the time required for reaching the time as a waiting time required in advance or for each section, and counting the time when the fire extinguishing signal receiving means receives the fire extinguishing signal In comparison with the timing means for timing the fire extinguishing operation elapsed time, the reception results of the fire signal receiving means and the fire extinguishing signal receiving means, the waiting time required, and the fire extinguishing operation elapsed time, Control means for holding the determination of the interlock control means, and the control means, when there is a fire extinguishing section that has been extinguished in advance, when the fire signal receiving means specifies the subsequent fire section, the fire extinguishing Comparing the operation elapsed time and the standby time required, the determination of the interlock control means to the fire extinguishing zone corresponding to the subsequent fire zone is suspended when the fire extinguishing operation elapsed time is less than the standby time required. When the fire extinguishing operation elapsed time is equal to or longer than the waiting time required, permission is given.

  In this invention, zones belonging to independent fire extinguishing facilities or zones where spaces are not physically shielded are grouped to form a zone, and zones belonging to each zone are registered in advance. And a zone setting means for storing and a method for determining the order of fire extinguishing sections to be activated or the order of fire extinguishing sections to be activated when the fire signal receiving means identifies a fire compartment. A fire extinguishing order setting means for storing, and when the fire signal receiving means specifies a fire section, the interlock control means refers to the registered content of the fire extinguishing order setting means regarding the zone to which the fire section belongs. The order of fire extinguishing sections to be activated is determined.

  According to the present invention, the registration contents registered and stored in advance in the fire extinguishing order setting means are high evacuation difficulty, proximity from the evacuation exit, or the size of the pipe volume connected to the fire extinguishing means, Or the order of the section which starts the said fire extinguishing means artificially determined in any one or any combination of the quantity of the fire extinguishing means arranged, or the high economic value Or the rate at which the fire detection means detects a fire, the physical quantity detected by the fire detection means or the rate of increase of the physical quantity per unit time, or the quantity of the fire detection means detected by the fire or the quantity When the rate of increase per unit time, or the level of the fire section, or the fire extinguishing means is provided with a heat sensitive part and an operation signal output means for the heat sensitive part, the quantity of the fire extinguishing means operated by the heat sensitive part Any one of the rate of increase of the quantity per unit time, or a method for determining the order of the sections for activating the fire extinguishing means, which is automatically determined by any one of a plurality of combinations It is characterized by.

  In the present invention, the interlock control means has a maintenance mode that can be set for each zone, and in the zone in which the maintenance mode is selected, the interlocking operation for determining a fire extinguishing section that is activated corresponding to a fire section is cut off. If the fire-off means belonging to the zone for which the maintenance mode is selected is provided with a heat-sensitive part and an operation signal output means for the heat-sensitive part, it depends on the fire signal from the fire detection means. And a single mode for controlling to activate the fire extinguishing means in response to the heat sensitive part operation signal.

  According to the present invention, fire extinguishing means and fire detection means are arranged corresponding to each section, and control of fire extinguishing equipment that controls to activate the corresponding fire extinguishing means in conjunction with a fire signal from the fire detection means A method for receiving a fire signal, identifying a fire zone, determining a fire extinguishing zone to be activated in response to the fire zone, and receiving a fire extinguishing signal output by the fire extinguishing means during fire extinguishing The time required from the start of the fire extinguishing means until reaching the specified fire extinguishing operation is registered and stored in advance as a waiting time required for each batch or section, and the fire extinguishing means is started. When the fire extinguishing operation elapsed time is counted, and when there is a fire extinguishing section that is extinguished in advance, the subsequent fire section is specified, the fire extinguishing operation elapsed time is compared with the waiting time required. Based on the decision Suspend the output of the start signal to the fire extinguishing means of the fire extinguishing section when the fire extinguishing operation elapsed time is less than the standby time required, and permit when the fire extinguishing operation elapsed time is equal to or longer than the standby time required. It is characterized by.

  The present invention groups zones that belong to independent fire extinguishing equipment or zones that are continuous without being physically shielded to form zones, and each zone belongs to each zone and fire. When a section is specified, the order of the fire extinguishing section to be activated or the method of determining the order of the fire extinguishing section to be activated is registered and stored in advance for each zone, and the fire section is identified.

[Embodiment 1]
<Technical thought>

  In FIG. 1, the protection section A (hereinafter referred to as section A) and the protection section (hereinafter referred to as section B) are not physically shielded, that is, are not separate spaces separated by walls, but are adjacent to each other. It shall be a continuous space. In the sections A and B, fire detectors 8a and 8b are disposed as fire detecting means. When a fire breaks out in such an installation situation, the section where the fire detector fires (hereinafter referred to as fire section) and the section where the fire source to be extinguished (hereinafter referred to as true fire section) are not necessarily the same. There are things that do not.

  For example, when the fire detectors 8a and 8b are smoke detectors, when a fire occurs in any of the sections A and B where there is air flow between each other, the fire detection that is far from the place where the fire occurred is caused by wind or airflow. Smoke will flow through the vessel, which may trigger a fire first. This is a phenomenon that can occur when the air conditioner is in operation, when wind is blowing from a window leading to the outside world, or when there is a temperature difference in the room. The fire detectors 8a and 8b are heat detectors. Even if it exists, it is the same even if it is a gas leak detector.

  In other words, when a fire breaks out, fire, heat, smoke and gas are carried from the fire source F1 in the zone A toward the zone B, and the fire detector is placed in the zone B far from the fire source F1. There is a risk that 8b may fire before the fire detector 8a (see FIG. 1).

  In addition, when the fire detectors 8a and 8b detect the radiation such as infrared rays and ultraviolet rays emitted from the fire source, it can be said that there is almost no influence by the airflow as described above. In general, the fire monitoring areas are arranged so that there are overlapping areas so that the blind spots disappear. In such a situation, if the fire source F2 exists near the boundary line between the sections A and B, it is no wonder which of the fire detectors 8a and 8b fires first, and these fires occur at the same time. There is also a risk of reporting.

  In addition, this type of fire detector that detects radiation from a fire source is also affected by reflections from structures such as walls, pillars, windows, etc., fixtures, etc. Although facility design and construction are performed with consideration, there is a possibility that the fire section may be different from the true fire section.

  In such a case, according to the conventional control method, one of the fire detectors 8a or 8b generates a fire, and the fire extinguishing system in the same section is started in conjunction with this. Another fire detector may trigger a fire and the other fire extinguishing system corresponding to this fire may be activated before the fire extinguishing system becomes the specified fire fighting operation.

  And these fire extinguishing systems are provided with a common pressurized water supply device 5 and a common primary pipe 6, and the water supply capacity is not doubled when the two fire extinguishing systems operate simultaneously. It will take time to reach the specified fire fighting operation. That is, an effective fire extinguishing operation is delayed.

  Therefore, the inventor of the present invention has defined the time required for the extinguishing means extinguishing in the section to reach the specified fire extinguishing operation as the waiting time required when there is a section extinguished in advance. .

  When the fire extinguisher is a wet sprinkler fire extinguisher, the secondary pipe is filled with water up to the sprinkler head.Therefore, during the waiting time, the pressurized water supply device is started and the water pressure for fire extinguishing is determined by the position of the sprinkler head. The time required to reach the pressure is sufficient, but in the case of the dry sprinkler fire extinguishing equipment, the secondary side pipe is not always filled with water, so it takes more time to fill it up. The Japanese Fire Service Act stipulates that the specified fire extinguishing operation be performed within 60 seconds. That is, in Japan, the sprinkler fire extinguishing equipment is designed so that the prescribed fire extinguishing operation is performed within 60 seconds, so the standby time required is 60 seconds at the longest. That is, the required waiting time may be set to 60 seconds or less.

  Then, the inventor intensively examined and followed the section (hereinafter referred to as the fire extinguishing section) that activates the fire extinguishing means until the time after the fire extinguishing means that had been extinguished before reaching the waiting time is reached. The process leading up to sending out the start signal is suspended, and the fire extinguishing operation time of the fire extinguishing section that has been extinguished in advance reaches the waiting time required to perform the specified fire extinguishing operation. When it is done, if the restriction to the subsequent fire extinguishing section is canceled, that is, the activation is permitted and the fire extinguishing operation is performed, the fire detector at a location different from the fire source position will fire first. Even if it did, I thought that it could extinguish effectively.

  That is, if the true fire zone coincides with the fire zone or fire extinguishing zone, the fire can be quickly extinguished. In addition, even if they do not match, the fire detector in the section where the fire source is located will generate a subsequent fire while suppressing the spread of fire to the section during the fire extinguishing operation. Fire extinguishing system that starts afterwards can be extinguished. The standby time required from the start of the fire extinguishing system that newly enters the fire extinguishing operation to the specified fire extinguishing operation is controlled so that the subsequent fire extinguishing system does not start. We learned that fire extinguishing can be performed.

The invention according to the present embodiment has been made based on the knowledge of the inventors as described above.
<Overall configuration>
Here, the configuration of the fire fighting equipment control system according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 and 2.

In addition, although the control system of the fire extinguishing equipment according to the first embodiment controls a plurality of sections, for the sake of simplicity, a single fire extinguishing system as two fire extinguishing means corresponding to two sections is provided. The pre-actuated sprinkler fire extinguishing equipment will be described.

  Fire detectors 8a and 8b are disposed in the two sections A and B, respectively, so that when the fire detector 8a or 8b detects a fire, a fire signal is sent to the fire receiver 9, respectively. It is electrically connected to the fire receiver 9.

  The fire receiver 9 identifies the section to which the fire detector that has fired belongs, that is, the fire section, by the fire signal from the fire detectors 8a and 8b, and sends a fire signal including the fire section information. It is electrically connected to the fire extinguishing system 10.

  Moreover, the fire extinguishing system control panel 10 sends a valve opening signal to the pre-actuating valve 1a or 1b as a start signal for a fire extinguishing system that protects the corresponding section, that is, a fire extinguishing section, according to the fire section of the received fire signal. Thus, the pre-actuating valves 1a and 1b are electrically connected. Further, the pre-actuating valves 1a and 1b are provided with a pressure switch (not shown) on the secondary side thereof, and the pre-acting valve 1a or 1b is opened so that fire-extinguishing water flows into the secondary-side piping 2a or 2b. When the pressure switch is activated, the pressure switch provided in the pre-actuating valves 1a and 1b and the fire extinguishing system control panel 10 are electrically connected so that the fire extinguishing signal is sent to the fire extinguishing system control board 10. Connected.

  Further, the primary piping 6 of the pre-actuating valves 1a and 1b is constantly pressurized and connected to the discharge port of the pressurized water supply device 5. The pressurized water supply device 5 is connected to a fire-fighting water tank (not shown) so as to pump up fire-fighting water. A pressure switch 7 is connected to the primary side pipe 6 to detect a pressure drop accompanying opening of the pre-actuating valve 1a or 1b, and to the fire pump control panel 11 so as to operate the pressurized water supply device 5. Connected to. The fire pump control panel 11 controls the operation of the pressurized water supply device 5 and is electrically connected to the pressurized water supply device 5.

Moreover, the secondary side of the pre-actuating valves 1a and 1b has two fire extinguishing systems divided for each of the sections A and B. The secondary end of the secondary side pipe 2a is connected to the secondary side of the pre-actuating valve 1a disposed in the section A, and the terminal end of the secondary side pipe 2a branches in the section, and a plurality of falling A plurality of sprinkler heads 3a that protect the section A are connected via the pipe 4a. Similarly, the secondary end of the secondary side pipe 2b is connected to the secondary side of the pre-actuating valve 1b disposed in the section B, and the terminal end of the secondary side pipe 2b branches in the section. A plurality of sprinkler heads 3b that protect the section B are connected to each other through the falling pipe 4b.
<Control system configuration>
Next, based on FIG. 2, the structure of the fire extinguishing system control board 10 as a control system in this invention is demonstrated.

  The fire extinguishing system control panel 10 receives the fire signal from the fire receiver 9 based on the fire signals from the fire detectors 8a and 8b, and identifies the fire signal receiving unit 10a as a fire signal receiving means for identifying the fire section, and the identification A control unit 10d as interlocking control means for determining a fire extinguishing zone to be activated in response to the fire zone, and a fire extinguishing system of the fire extinguishing zone is activated based on the determination of the control unit 10d, that is, the pre-actuating valve 1a Alternatively, as an activation signal output unit 10c serving as an activation signal output unit that outputs an activation signal that opens the valve 1b, and an in-extinguishing signal reception unit that receives an in-extinguishing signal sent from the opened pre-actuating valve 1a or 1b. When the fire extinguishing signal receiving unit 10b and the fire extinguishing signal receiving unit 10b receive the fire extinguishing signal, the elapsed time after the start of the fire fighting operation is started (hereinafter, fire extinguishing operation). Comprising a clock unit 10g as counting means for counting the elapsed time) for each extinguishing section, the.

 In addition, the said control part 10d is the said fire extinguishing which the reception result of the fire signal receiving part 10a and the fire extinguishing signal receiving part 10b, the said waiting time registered into the standby time setting part 10j, and the time measuring part 10g timed. In contrast to the operation elapsed time, the determination of the fire extinguishing section to be started in conjunction is suspended, and it also functions as a restricting means for controlling the start signal output unit 10c to temporarily stop outputting the start signal.

  The fire extinguishing system control panel 10 includes a display unit 10h serving as a display unit that displays the entire fire extinguishing equipment or the operation status and state of the fire extinguishing system control panel 10, contents set and registered in the fire extinguishing system control panel 10 described later, And an operation unit 10i as an operation means for performing manual operation and inspection operation of the fire extinguishing equipment and the fire extinguishing system control panel 10, setting registration operation of the fire extinguishing system control panel 10 which will be described later, and the like.

  In addition, the fire extinguishing system control panel 10 sets a standby time for registering and storing the required time required for reaching the specified fire extinguishing operation after the activated fire extinguishing system is started as a standby time required in a batch or for each section. A standby time setting unit 10j as means is provided.

In this embodiment, the zone setting unit 10e and the fire extinguishing order setting unit 10f illustrated in the fire extinguishing system control panel 10 are not used and can be omitted.
<Operation>
Next, with reference to FIG. 1 thru | or FIG. 3, operation | movement of the control system of the fire extinguishing equipment which concerns on embodiment of this invention is demonstrated.

  When fire F1 occurs in section A (see FIG. 1), when fire detector 8a fires, a fire signal from fire detector 8a is sent to fire receiver 9, and the fire is received. The receiver 9 issues a fire alarm and sends a fire signal including fire zone information to the fire extinguishing system control panel 10.

  The fire extinguishing system control panel 10 that has received the fire signal at the fire signal receiving unit 10a sends an activation signal for opening the pre-actuating valve 1a from the activation signal output unit 10c so that the control unit 10d extinguishes the section A. To do.

  The pre-actuating valve 1a that has received the activation signal is opened, and fire-extinguishing water is fed into the secondary pipe 2a. And the pressure of the secondary side piping 2a and the primary side piping 6 which were connected by valve opening of the pre-actuating valve 1a falls, the pressure switch 7 which detected this pressure drop sends out a signal to the fire pump control panel 11, The fire extinguishing pump control panel 11 that has received the message starts the operation of the pressurized water supply apparatus 5. And the water for fire extinguishing pumped from this pressurized water supply apparatus 5 which started operation fills the secondary side pipe 2a through the primary side pipe 6 and the pre-actuated valve 1a opened. After the waiting time determined by these pipe volumes and the water supply capacity of the pressurized water supply device 5 has passed, the fire-extinguishing water that has reached the sprinkler head 3a reaches a specified pressure, and the sprinkler connected to the secondary pipe 2a. When any of the heads 3a is opened by the heat of a fire, the opened sprinkler head 3a performs a specified fire extinguishing operation to extinguish the fire source F1.

  During this time, a pressure switch (not shown) provided on the secondary side of the pre-actuating valve 1a is operated, and a fire extinguishing signal indicating that the fire extinguishing operation of the system in the section A is performed is performed. It is sent to the middle signal receiving unit 10b.

  The timing unit 10g of the fire extinguishing system control panel 10 that has received the fire extinguishing signal starts timing, and counts the fire extinguishing operation elapsed time after the fire extinguishing of the section A is started.

  The control unit 10d of the fire fighting system control panel 10 compares the required standby time registered and stored in the standby time setting unit 10j with the fire extinguishing operation elapsed time, and the fire extinguishing operation elapsed time becomes the required standby time. If not, even if a new fire signal is received by the fire signal receiving unit 10a and a new fire zone is recognized, the decision to hold and pause the decision to send the start signal to the corresponding fire extinguishing system And control so as not to output a new activation signal from the activation signal output unit 10c.

  That is, even when fire extinguishing operation is performed in the section A, even if the fire detector 8b fires and the fire signal of the section B is received by the fire signal receiving unit 10a via the fire receiver 9, the section Until the fire extinguishing operation in A reaches the specified fire extinguishing operation, the start signal for opening the pre-actuating valve 1b is not output from the start signal output unit 10c, and the fire extinguishing operation elapsed time in the section A reaches the required standby time. The start signal for opening the pre-actuating valve 1b is controlled to be output from the start signal output unit 10c.

  At this time, if the fire source F1 goes to extinguishment due to the fire extinguishing operation of the section A or the fire power is decreasing, the pre-actuating valve 1b of the section B is opened, and the secondary pipe 2b is filled with fire-extinguishing water. Even if the water is sprinkled, if the sprinkler head 3b on the section B side is not opened by the heat of the fire, the section B will not discharge water. On the contrary, when the fire power of the fire source 1 in the section A spreads without decreasing, the sprinkler head 3b is opened by the heat of the fire and the fire extinguishing operation is performed on the section B.

  The operation when a fire occurs at a position (not shown) located in the section B conforms to the above description although there is a difference in the section.

  Consider cases that differ from the above explanation. When a fire has occurred at the fire source F1 located in the section A, and the fire detector 8b in the section B far from the fire source F1 has fired first, a fire signal from the fire sensor 8b is generated. The fire receiver 9 that is sent to the fire receiver 9 receives the fire alarm and issues a fire alarm, and sends a fire signal including fire section information to the fire extinguishing system control panel 10.

  The fire extinguishing system control panel 10 that has received the fire signal at the fire signal receiving unit 10a sends an activation signal for opening the pre-actuating valve 1b from the activation signal output unit 10c so that the control unit 10d extinguishes the section B. To do.

  The pre-actuating valve 1b that has received the activation signal is opened, and fire-extinguishing water is fed into the secondary side pipe 2b. When any of the sprinkler heads 3b connected to the secondary side pipe 2b is opened by the heat of the fire, the pressure in the secondary side pipe 2b and the primary side pipe 6 communicated by opening the pre-actuating valve 1b decreases. The pressure switch 7 that has detected this pressure drop sends a signal to the fire pump control panel 11, and the fire pump control panel 11 that has received the signal starts operating the pressurized water supply device 5. The fire-extinguishing water pumped from the pressurized water supply device 5 that has started operation goes to the sprinkler head 3b that has been opened through the primary side pipe 6, the pre-actuated valve 1b that has been opened, and the secondary side pipe 2b. The sprinkler head 3b performs a fire extinguishing operation in the specified section B after the waiting time determined by these pipe volumes and the water supply capacity of the pressurized water supply device 5 elapses. Since the fire source F1 is located in the section A, there is a high possibility that this fire extinguishing operation will not be effective water discharge for fire extinguishing, but the spread of fire from the fire source F1 in the section A to the section B can be suppressed.

  Then, since the fire detector 8a in the section A, which is a fire section, issues a fire, the pre-actuation valve 1a in the section A is opened while preventing the spread of fire to the section B, and the secondary pipe 2a is opened. Since the water for fire extinguishing is pumped and the sprinkler head 3a that is opened by the heat of the fire performs a fire extinguishing operation, the fire source F1 is extinguished.

  Even if the pre-actuating valve 1b in the section B is opened as described above, the water is not discharged in the section B unless the sprinkler head 3b is opened by the heat of fire. Since the fire extinguishing signal is not sent from the section B, the above-described regulation does not occur. Therefore, when the fire detector 8a in the section A fires, the fire extinguishing system of the corresponding section A can be started immediately. . Then, when the sprinkler head 3a in the section A is opened by heat from the fire, the fire extinguishing operation in the section A is started, so that the fire source F1 can be quickly extinguished.

By controlling as described above, as described above, there is a possibility that the section far from the fire source may perform the fire extinguishing operation first, but anyway, the fire extinguishing system that started the fire extinguishing operation first is quickly specified. The fire extinguishing action was reached. This allows for quick fire extinguishing if the fire compartment matches the true fire compartment. In addition, even if these do not match, the fire detector in the true fire compartment will fire afterwards while suppressing the spread of fire to the fire extinguishing operation, Subsequent fire extinguishing systems can be extinguished. And for a fire extinguishing system that has newly entered a fire extinguishing operation, the standby time required from the start until the specified fire extinguishing operation is further controlled so that the subsequent fire extinguishing system does not start. Can be extinguished quickly.
<Other configurations>

  In addition, between the fire detectors 8a and 8b and the fire receiver 9, between the fire receiver 9 and the fire extinguishing system control panel 10, and between the fire extinguishing system control panel 10 and the pre-actuating valves 1a and 1b, Although FIG. 1 shows that each is electrically connected by an individual electric wire, these may be electrically connected by a common electric wire so that multiplex transmission is performed.

When such multiplex transmission is performed, if the terminal device such as the fire detectors 8a and 8b and the pre-actuating valves 1a and 1b transmits or receives individual electrical signals, the fire receiver 9 or the fire extinguishing system control panel 10 is electrically connected with a common wire between the terminals 10 to perform multiplex transmission, and is electrically connected to the terminal device with individual wires to be transmitted or received with individual signals. A repeater (not shown) that performs the above may be provided so as to be interposed between the terminal device and the fire receiver 9 or the fire extinguishing system control panel 10.
[Embodiment 2]
<Technical thought>
A fire fighting equipment control system according to Embodiment 2 of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected about the location with the same structure as Embodiment 1, and the description is abbreviate | omitted.

  As in the first embodiment, in FIG. 1, the section A and the section B are not confined physically, that is, are not separate spaces separated by walls, but are adjacent and continuous spaces. Shall. In such a case, the fire section when the fire detector 8a or 8b fires may not necessarily match the true fire section where the fire source to be extinguished is located. As explained in. That is, when a fire occurs, there is a risk that the fire detector 8b disposed in the section B far from the fire source F1 may fire before the fire detector 8a (see FIG. 1).

  Here, the inventor faced a new challenge. That is, when the fire source F2 is generated near the boundary between the sections A and B (see FIG. 1), there is a possibility that the fire detectors 8a and 8b may issue a fire almost simultaneously.

  In such a case, there is a problem that the fire extinguishing systems in the sections A and B may be controlled so as to be activated almost simultaneously. That is, even if one fire extinguishing system is activated, if the fire extinguishing system that has been activated first has not yet started extinguishing, the pressure switch provided on the secondary side of the pre-actuating valve 1a or 1b does not send out a fire extinguishing signal. The restriction by the waiting time required cannot be applied, and there is a possibility that both fire extinguishing systems in sections A and B may be activated.

  If the fire extinguishing means arranged in each of the sections A and B are different fire extinguishing equipments that operate independently, there is no problem, but the pre-acting sprinkler fire extinguishing equipment shown in FIG. In the case of fire extinguishing equipment such as divided, the pressurized water feeding device 5, the primary side pipe 6 and a fire fighting water tank (not shown) are shared, and the water feeding capacity doubles when two fire extinguishing systems operate simultaneously. Therefore, it takes time until the fire extinguishing system that has been started reaches the specified fire extinguishing operation. That is, an effective fire extinguishing operation is delayed.

  Therefore, the inventor diligently studied and introduced the concept of a zone in which a plurality of sections are grouped. That is, the zones belonging to independent fire extinguishing equipment and the zones where the spaces are not physically shielded are grouped to form a zone, and the zone belonging to each zone is registered and stored in advance. I thought about extinguishing each zone as a unit.

  And it belongs to the zone where fire broke out using the control method disclosed in the first embodiment, in which the fire extinguishing system that was previously extinguished reaches the specified fire extinguishing operation and then starts the next fire extinguishing system. The knowledge that this problem can be solved by sequentially starting the fire extinguishing system of the compartments according to a predetermined order or rule was obtained.

The invention according to the present embodiment has been made based on the knowledge of the inventors as described above.
<Configuration>
First, the configuration of the invention according to Embodiment 2 will be described with reference to FIG.

  The difference in configuration from the first embodiment is that, in the fire extinguishing system control panel 10 as a fire extinguishing equipment control system, a zone setting unit 10e as zone setting means for registering and storing sections belonging to each zone in advance, For each zone, a fire extinguishing order setting unit 10f is provided as a fire extinguishing order setting means for registering and storing in advance a method for determining the order of fire extinguishing sections to be activated or the order of fire extinguishing sections to be activated.

  The zone setting unit 10e forms a zone by grouping together sections belonging to independent fire extinguishing equipment or sections where the space is not physically shielded, and sets the sections belonging to each zone. It is registered and stored in advance.

  In the case shown in FIG. 1, there is no independent fire extinguishing equipment other than the dry pre-actuated sprinkler fire extinguishing equipment shown in the figure, but an independent fire extinguishing equipment not shown, for example, a foam fire extinguishing equipment, a wet pre-acting sprinkler fire extinguishing equipment If there are equipment, non-pre-acting wet or dry sprinkler fire extinguishing equipment, gas fire extinguishing equipment, water spraying equipment, etc., and these are controlled by the same fire extinguishing system control panel 10, these are set in different zones, It is better to be able to fire extinguish independently.

  Here, it is assumed that the spaces in the sections A and B are set in the same zone as the sections that are continuous without being physically shielded. That is, in the zone setting unit 10e, for example, section A and section B are registered and stored in the first zone.

  In addition, when the space of three or more divisions is continuing without being physically shielded, it is usually sufficient to form a zone by grouping adjacent divisions. That is, in a plurality of sections arranged in a straight line, it is impossible to imagine a case in which a fire is reported at both ends by skipping a space in the middle. However, there are exceptional cases where all three sections are adjacent to each other, in which case they should all be considered the same zone. In addition, if the fire detection means detects infrared or ultraviolet radiation from a fire source, it is possible that a fire farther away may be detected by jumping over a section in the middle. The characteristics of the fire detector need to be considered. In other words, the sections that are grouped to form the zones are appropriately set in consideration of the layout of the sections, the building structure therebetween, and the characteristics of the fire detection means.

  In addition, the fire extinguishing order setting unit 10f pre-registers, for each zone, a method for determining the order of the fire extinguishing zone to be activated or the order of the fire extinguishing zone to be activated when the fire signal receiving unit 10a identifies the fire zone. And memorize it.

Then, the control unit 10d receives the fire signal reception unit 10a, the fire extinguishing signal reception unit 10b, the standby time registered in the standby time setting unit 10j, and the fire extinguishing timed by the time measuring unit 10g. In contrast to the operation elapsed time, the determination of the fire extinguishing section to be started in conjunction is suspended, and the start signal output unit 10c functions as a control unit that controls to temporarily stop outputting the start signal, and fire When the signal receiving unit 10a identifies a fire zone, a function of controlling to determine the order of fire extinguishing zones to be activated is added with reference to the registered content of the fire extinguishing order setting unit 10f regarding the zone to which the fire zone belongs.
<Operation>
Next, the operation of the second embodiment will be described with reference to FIG. Refer to FIG. 1 and FIG. 2 for the configuration of each part in the explanatory note.

  When the fire signal receiving unit 10a as the fire signal receiving means receives the fire signal from the fire receiver (S001) and identifies the fire section (S002), the control section 10d as the interlock control means belongs to the fire section. The zone is identified by referring to the zone setting unit 10e as the zone setting means, and the zone to which the fire section belongs is identified (S003), and the registered contents of the fire extinguishing order setting unit 10f as the fire extinguishing order setting means are applicable. A method for determining the order of fire extinguishing sections to be activated or the order of fire extinguishing sections to be activated is read out and the order of fire extinguishing sections to be activated is determined (S004).

  Here, the control unit 10d confirms the reception result of the extinguishing signal reception unit 10b, and confirms whether or not there is a extinguishing fire extinguishing section preceding the zone to which the fire section belongs (S005). If there is a fire extinguishing section that is extinguished in advance in the same zone, check whether the fire extinguishing operation duration of the fire extinguishing section is equal to or longer than the required waiting time (S006). , Wait until the fire extinguishing operation duration exceeds the required standby time, if the fire extinguishing operation duration is longer than the required standby time, or if there is no fire extinguishing section in the same zone prior to fire extinguishing, Based on the determination, the control unit 10d outputs an activation signal to the fire extinguishing section to be activated via the activation signal output unit 10c (S007).

  When the fire extinguishing equipment to be controlled is the pre-actuated sprinkler fire extinguishing equipment shown in FIG. 1, the pre-actuating valve 1a or 1b corresponding to the fire extinguishing section is opened (see FIG. 1). Then, the control unit 10d is activated and a fire extinguishing signal is sent from a pressure switch (not shown) provided on the secondary side of the pre-actuating valve 1a or 1b in the section where the fire is started, and this is used as a fire extinguishing signal receiving means. Received by the fire-extinguishing signal receiver 10b.

  The control unit 10d waits until a fire extinguishing signal is received from the fire extinguishing section activated by the fire extinguishing signal receiving unit 10b. When the fire extinguishing signal is received, the time measuring unit 10g as a time measuring unit counts the fire extinguishing operation elapsed time. The process starts and proceeds to the next step (S008).

Then, the control unit 10d refers to the standby time setting unit 10j in which the required standby time is registered for each batch or section, reads the required standby time corresponding to the fire extinguishing section, and compares this with the fire extinguishing operation elapsed time. (S006).
And, when the fire extinguishing operation elapsed time is less than the required standby time, it waits until the fire extinguishing operation elapsed time is equal to or longer than the required standby time, and when the fire extinguishing operation elapsed time is equal to or longer than the required standby time, it is determined first. In accordance with the fire extinguishing zone order, an activation signal is sent to the subsequent fire extinguishing zone (S007).

  Thereafter, this operation is repeated until all the fire extinguishing sections are activated in accordance with the fire extinguishing section order determined previously (S001 to S008).

  In the situation where the fire receiver 9 is restored and the fire signal is not input to the fire signal receiving unit 10a, when the restoration operation is performed on the fire extinguishing system control panel (S009), the fire extinguishing signal receiving unit 10b is in the fire extinguishing signal. Is received (S010), this is recovered (S011), and when the fire extinguishing signal is not received, the fire signal reception unit 10a waits in a normal state until receiving the fire signal (S009).

  When the secondary side pipe 2a or 2b in which the pre-actuating valve 1a or 1b is opened is filled with fire extinguishing water, the sprinkler head 3a or 3b connected to the secondary side pipe 2a or 2b is opened by the heat of the fire. Water discharge starts from the sprinkler head 3a or 3b that has been opened. By opening the pre-actuating valve 1a or 1b and opening the sprinkler head 3a or 3b, the internal pressure of the primary side pipe 6 communicating with these drops, and this is detected by the pressure switch 7 connected to the primary side pipe. The fire extinguishing pump control panel 11 sends a signal, and the fire extinguishing system control panel 11 that has received the signal starts the pressurized water supply device 5. 6. A specified fire extinguishing operation is performed from the opened sprinkler head 3a or 3b via the opened pre-actuating valve 1a or 1b and the secondary side pipe 2a or 2b (see FIGS. 1 and 2).

  The above describes the operation of grouping consecutive sections without being physically shielded to form a zone and integrally extinguishing the fire for this one zone. When a zone is formed by grouping consecutive sections that are not shielded, the same control may be performed for each zone.

  And, in principle, the linkage control of the fire extinguishing operation is not performed between these zones. However, if there is a possibility that the fire water tank is shared and the water source is depleted, the control unit 10d adds up the number of zones or compartments that perform fire fighting operations or the total amount of water consumed by each zone or compartment. You may control to add a restriction | limiting.

  Moreover, when forming a zone with an independent fire extinguishing facility, the same control as described above may be performed when grouping continuous sections without being physically shielded as described above.

In addition, when the above-described integrated fire extinguishing control is not performed in an independent fire extinguishing facility, the zones belonging to each zone are registered in the zone setting unit 10e and the fire extinguishing order is set for each zone organized for each independent fire extinguishing facility. For example, when the fire signal receiving unit 10a receives a fire signal, the setting unit 10f does not control the fire extinguishing order, for example, defines a code that does not perform the fire extinguishing order control and registers the code. The control unit 10d reading the code registered in the fire extinguishing order setting unit 10f may be configured not to control the fire extinguishing order for the zone to which the fire section belongs.
<Order of fire-fighting section>

  Here, consider the order of fire extinguishing sections to be registered or registered in the fire extinguishing order setting unit 10f, or a method for determining the order.

  First, the inventor considered a method for automatically determining the order of fire extinguishing sections to be activated in the order estimated to be close to the fire source. That is, the fire extinguishing section is automatically determined by a method for determining a predetermined order. If the fire is extinguished from the fire extinguisher that is closest to the fire source, it can be extinguished quickly before the fire source grows. It is one of the effective means.

  Therefore, it was considered to introduce an analog system as described in the first embodiment. When such an analog system is adopted, a physical quantity detected by the fire sensor, for example, temperature information, a method for determining the order of the fire extinguishing section to be activated, which is previously registered and stored in the fire extinguishing order setting unit 10f, is stored. The order of increasing numerical values such as smoke concentration and gas concentration, or the order of increasing rate of increase per unit time can be used.

  In this way, by introducing an analog system, it is possible to estimate the fire detector closest to the fire section from the magnitude of the physical quantity detected by the fire detector 8a or 8b and the magnitude of its increase rate. At least, the section identified as the fire section has the effect of increasing the probability of being closest to the fire occurrence place.

  In addition, even if an analog system is not used, it is close to the fire source, just like when an analog system is installed using a classic fire detector that sends a fire signal after making a fire judgment. There is also a way to estimate the fire compartment.

  For example, it is the speed at which the fire detector issues a fire, that is, the order of the fire sections that have issued the fire signal received by the fire signal receiving unit 10a. Fire detectors near fire sources are more likely to fire early.

  In addition, for example, the order of the fire detectors having a large number of fire detectors or the order of increasing the number of units per unit time is large. The closer to the fire source, the greater the expansion, so the more fire detectors that have reported fires, or the greater the rate of increase in the number of fire detectors, the more likely the area is closer to the fire source. . However, it is necessary to keep in mind that during this estimation, the fire may spread somewhat, and a considerable number of fire detectors must be installed in each section.

  Also, for example, when the fire extinguishing means is provided with a heat sensitive part and an operation signal output means for the heat sensitive part, the order of the number of the fire extinguishing means in which the heat sensitive part is activated, or the rate of increase in the number per unit time Is a big order. For example, as disclosed in Japanese Patent Application Laid-Open No. 2003-275337, the use of a sprinkler head provided with a cover that falls by detecting the heat of a fire and a switch that detects the fall, the fire is detected. Since the operation of the sprinkler head can be detected, the number can be counted. In that respect, it is the same principle as the above-mentioned method, in which the order of fire extinguishing sections is determined by the number of fire detectors that have fired or the rate of increase.

  Further, for example, fire extinguishing sections may be determined in the order of the fire section hierarchy. In a normal building structure, if the hierarchy is different, it becomes a different zone, but in the case of a colonnade space or a section that is connected to it, the order of the fire extinguishing section is determined from the lower floor estimated to be the source of the fire There are cases where this happens.

  While determining any one or any combination of the methods of determining the order of fire extinguishing sections to be activated listed above, while confirming the registered content on the display unit 10h of the fire extinguishing system control panel 10, It is registered and stored in the fire extinguishing order setting unit 10f from the operation unit 10i.

  Although the method listed above can estimate the section close to the fire source and automatically determine the order of the fire-extinguishing section, it may determine the fire-extinguishing operation from the fire-extinguishing section far from the location of the fire. Therefore, it is dangerous to determine the fire extinguishing section in one place, and it is emphasized that this is a method for determining the priority order of sequentially starting the fire extinguishing sections in the zone.

  Here, the inventor further examines, regardless of where the fire belongs in the zone belonging to the zone formed by grouping as described above, for example, even if the fire detector 8a in the zone A fires, Even if the fire detector 8b in the section B issues a fire, by recognizing that a fire has occurred somewhere in the zone to which these sections A and B belong, and by determining a predetermined order or order, It was also considered to determine the fire extinguishing section.

  That is, when a fire occurs in the same zone, unless the place where the fire occurs can be specified, the section where the fire is extinguished is not always close to the fire occurrence place. Therefore, we changed the way of thinking from the idea of activating a fire extinguishing section that is likely to be as close as possible to the location of the fire and extinguishing it as soon as possible, so we thought about reducing human damage and economic damage as much as possible is there.

  That is, for the purpose of minimizing human damage, this is a method of determining the order of fire extinguishing sections in order from the section with the highest evacuation difficulty and registering it in advance by manual operation. Similarly, the order of fire extinguishing sections may be determined in the order from the evacuation exit to secure an evacuation route.

  Moreover, you may determine a fire extinguishing order with the magnitude | size of the piping volume connected to the fire extinguishing means. In the zone to which the fire section belongs, if it is desired to start the prescribed fire extinguishing operation as soon as possible, the fire extinguishing section order may be determined in ascending order of pipe volume. Conversely, when the fire extinguishing from the fire extinguishing means that takes the most time to reach the specified fire extinguishing operation is urgently performed, the order of the fire extinguishing sections may be determined in descending order of the pipe volume. Which one to select is appropriately determined in view of the facility usage situation and the fire fighting equipment arrangement situation.

  Moreover, you may determine a fire extinguishing division in order of the quantity of the fire extinguishing means arrange | positioned in the fire extinguishing division. That is, if the number of connected sprinkler heads and the like is determined in descending order, the fire extinguishing operation over a wider range is performed first.

  There is also a method of determining fire extinguishing zones in order of economic value. In other words, server rooms, vaults, department store precious metal departments, etc. should never be given priority over human damage, but it is worth considering when the assumption of human damage is low.

  From the operation unit 10i while determining any one or any combination of the fire extinguishing sections to be activated listed above and confirming the registered contents on the display unit 10h of the fire extinguishing system control panel 10. It is registered and stored in the fire extinguishing order setting unit 10f.

In addition, a method of randomly determining the order of the sections to be extinguished in the zone is also conceivable. Although it is a last resort when a fire can not be assumed, as mentioned above, it has priority over extinguishing the fire as soon as possible, saving as many human lives as possible, reducing the economic loss as much as possible, etc. This is not a desirable method.
[Embodiment 3]

  The inventor has realized that the zone can also be used for other applications by its definition. In other words, a zone is a grouping of sections belonging to independent fire extinguishing equipment, or sections where the space is not physically shielded, but this is used for inspection and repair work. I thought it could be used for

  A maintenance mode can be set for each zone (or in a batch), and the zone that is set to this maintenance mode is controlled to block the interlocking operation that determines the fire extinguishing zone that is activated in response to the fire zone. We obtained knowledge that the shut-off mode and the single mode that enables fire extinguishing means independently to be extinguished without depending on the fire signal from the fire detection means can be set and controlled for each zone.

The invention according to the present embodiment has been made based on the knowledge of the inventors as described above.
<Configuration>

The configuration as the control system is not different from that of the second embodiment. However, an operation means for setting the maintenance mode, an operation means for setting the interlocking cutoff mode, and an operation means for setting the single mode are added to the operation unit 10i for each zone or collectively. When these are set, display means for displaying the fact is added to the display unit 10h (see FIG. 2).
<Operation>

When the maintenance mode is set by the operation unit 10i, the control unit 10d identifies a partition belonging to the zone requested to enter the maintenance mode (hereinafter referred to as maintenance mode zone) by referring to the registration information of the zone setting unit 10e. These partitions are recognized as partitions set in the maintenance mode (hereinafter referred to as maintenance mode partitions).
(Linked cutoff mode)
First, the operation of the zone in which the interlocking cutoff mode is set by the operation unit 10i will be described.

  When the maintenance mode is not set, even if the interlocking cut-off mode is set by the operation unit 10i, the control unit 10d rejects this. This functions as a foolproof to prevent operation mistakes and forgetting operations. When the maintenance mode is set and the zone to be set to the interlocking cutoff mode is set by the operation unit 10i, the control unit 10d registers the section belonging to the zone to be set to the interlocking cutoff mode in the registration information of the zone setting unit 10e. And identify the identified section as an interlocking block section.

  When the fire signal receiving unit 10a receives the fire signal, the control unit 10d identifies the fire zone, identifies the zone to which the fire zone belongs by referring to the registration information of the zone setting unit 10e, and is further identified. If the zone belonging to the fire zone is further identified with reference to the registration information of the zone setting unit 10e, and these zones are the interlocking cutoff zone, the interlocking operation is not performed on the zone, and the start signal output unit Control is performed so that the start signal is not output from 10c.

  If it does in this way, even if the fire signal receiving part 10a receives a fire signal, the pre-acting valve 1a or 1b of the division which belongs to the zone set to the interlocking | blocking interruption | blocking mode will not open in response.

  Therefore, even if an automatic fire alarm facility including the fire detector 8a or 8b and the fire receiver 9 is being inspected or refurbished, the pre-actuating valve 1a or 1b malfunctions even if a fire signal is accidentally generated. This prevents the secondary side pipe 2a or 2b from being unnecessarily filled with water, and does not cause a water loss accident.

Further, even if a fire signal is generated for some reason during inspection or refurbishment of the fire extinguishing means, it is possible to prevent the pre-actuating valve 1a or 1b from malfunctioning. Or 2b is not filled with water and it is not necessary to cause a water loss accident. In addition, the fire extinguishing equipment that has been operated unexpectedly can prevent an accident in which a worker who is inspecting or repairing the equipment is injured.
(Single mode)
Next, the operation of the zone in which the single mode is set by the operation unit 10i will be described.

  When the maintenance mode is not set, even if the single mode is set by the operation unit 10i, the control unit 10d rejects this. This functions as a foolproof to prevent operation mistakes and forgetting operations. When the maintenance mode is set and the zone to be set to the single mode is set by the operation unit 10i, the control unit 10d refers to the registration information of the zone setting unit 10e for the section belonging to the zone to be set to the single mode. The identified section is recognized as a single section.

  Here, the single mode means that the fire extinguishing operation can be performed by the fire extinguishing equipment alone, and the operation linked to the fire alarm of the fire detector is unnecessary. For example, when an automatic fire alarm facility including the fire detectors 8a and 8b and the fire receiver 9 is being inspected, or when the automatic fire alarm facility is being repaired, a fire signal cannot be received. Even in the situation, it is possible to prevent a situation where the fire extinguishing equipment cannot automatically extinguish.

  Therefore, the fire extinguishing equipment that can be set to the single mode is limited to those that can perform an automatic fire extinguishing operation with the fire extinguishing equipment alone, and the fire extinguishing means includes a heat sensitive part and an operation signal output means for the heat sensitive part.

  For example, the pre-actuated sprinkler fire extinguishing equipment shown in FIG. 1 has been described as the pre-actuating valve 1a or 1b being opened in conjunction with the fire alarm of the fire detector 8a or 8b. The operation of is impossible.

  Here, the inside of the secondary side pipes 2a and 2b is set to pressurized gas or negative pressure, and further connected to the secondary side pipes 2a and 2b, and a head operation detecting means 12a (not shown) for detecting a pressure change inside the secondary side pipes 2a and 2b. 12b is provided.

  For example, normally, both the operation signal of the head operation detection means 12a or 12b as the operation signal output means of the heat sensitive part and the fire signal by the fire alarm of the fire detector 8a or 8b are in the same section. The control unit 10d controls the pre-actuating valve 1a or 1b to open when received by the fire extinguishing system control panel 10. That is, an AND operation is performed.

  In this way, the fire alarm of the fire detector 8a or 8b and the opening of the closed sprinkler head 3a or 3b having a heat sensitive part are aligned in the same section, thereby opening the pre-actuating valve 1a or 1b. It is possible to form a pre-actuated sprinkler fire extinguishing equipment called a so-called double action type that can fill the secondary pipe.

And about such a double action type pre-acting sprinkler fire extinguishing equipment, when the single mode is set, so that the pre-acting valve 1a or 1b can be opened only by the operation of the head operation detecting means 12a or 12b. What is necessary is just to make it control by the control part 10d.
(Zone formation in maintenance)

  The above is to explain that the zone for fire extinguishing interlock control as shown in the second embodiment can be used for maintenance or the like. good.

  For example, the fire fighting interlock control zones as shown in the second embodiment may be further grouped to form a higher maintenance zone. In this case, it can be realized by hierarchizing information to be registered in the zone setting unit 10e.

  In addition, a maintenance-dedicated zone may be formed separately from the fire-extinguishing interlocking control zone as shown in the second embodiment. In this case, a maintenance zone setting unit separate from the zone setting unit 10e may be newly provided, or the address in the nonvolatile memory formed by the zone setting unit 10e is divided into two, which are described in the second embodiment. Such a fire extinguishing interlocking control zone and a maintenance zone may be managed separately.

  In addition, the description content of the patent document described as a prior art can be introduce | transduced or used by reference as description of the technical element described in this specification.
