Description

  The present invention relates to a fire receiver that monitors a plurality of detectors and causes a district acoustic device to ring when a fire occurs, and a disaster prevention system including the fire receiver.

  In order to facilitate the management of the system using the fire receiver as described above, it is required to grasp the cause of the false alarm and take effective measures. As an example of prior art for displaying the occurrence of such a false alarm, the following Patent Document 1 includes a journal in which the receiver stores the address and time of a sensor in which a real fire alarm and a non-fire alarm (false alarm) occurred. A configuration to display is disclosed.

Japanese Patent Laid-Open No. 11-096470

  However, in the configuration as in Patent Document 1, since there is no record regarding the cause of non-fire reports in the journal, it is difficult to take specific measures such as smoking cessation even if the journal is investigated. there were.

  Therefore, in order to solve the above problems, it is an object of the present invention to provide a fire receiver and a disaster prevention system having a novel configuration capable of grasping an operating factor of a sensor particularly in the case of a non-fire.

  The fire receiver according to the present invention includes an operation factor input unit that receives a selection of an operation factor and accumulates it in a storage unit as an operation history each time a connected sensor is activated, and statistical information based on the accumulated operation history. In the operation factor input unit, the operation factor is classified into fire / non-fire, and in the case of non-fire, one of the assumed operation factors is selected in advance. Yes.

  The statistical information display unit is preferably configured to display statistical information of an operating factor selected in the case of the non-fire.

  The disaster prevention system according to the present invention includes the fire receiver.

  According to the present invention, since the fire receiver displays statistical information based on the operation history of the sensor, the administrator grasps the operation factor of the sensor at the time of non-fire from the display and responds to the false alarm. Appropriate measures can be taken. Accordingly, if the number of operation of the sensor is reduced, the burden on the administrator is reduced, so that the management can be concentrated.

These are the basic block diagrams of the disaster prevention system which applied this invention to the GR type receiver. Is an example of an alarm screen displayed at the time of alarm operation. Is an example of a fire determination screen. Is an example of an operating factor input screen. Is an example of a display screen of statistical information.

  The receiver 1 shown in FIG. 1 is installed in a building such as an apartment or a general commercial building.

  Fire receivers are generally categorized as P type 1 class, P type 2 class, and R type. The GR type receiver is obtained by adding a function to monitor and control the gas detector to the R type fire receiver. In a system using an R-type or GR-type receiver, a unique address is assigned to each fire detector 2, and signal transmission with designated addresses is performed between the receiver 1 and the fire detector 2. . Specifically, it may be polling in which the receiver 1 transmits a command signal designating an address and the fire detector 2 at the address returns a response signal.

  Hereinafter, the present invention will be described with respect to a disaster prevention system using a GR type receiver. However, the present invention can be similarly applied to a system using a P type first grade, P type second grade, or R type fire receiver.

  The receiver 1 has, as a basic configuration, an operation unit 11, a liquid crystal display unit 12, a district display window 13, an audio unit 14, a line control unit 15 that controls the fire detector 2 and the gas sensor 5, , A transfer unit 16 for transferring an abnormality to the outside, a CPU substrate 17, and a storage unit 18. The fire detector 2 and the transmitter 3 are connected via the fire line 21, the district acoustic device 4 is connected via the acoustic line 41, the gas detector 5 is connected via the gas line 51, and the control line Various interlocking devices 6 are connected via 61. Examples of the interlocking device 6 include a fire door, a smoke prevention device, and a water spray device. Note that the receiver 1 may be further connected to a printer, a sub-display device, and the like (not shown).

  As a characteristic configuration of the present invention, the operation unit 11 of the receiver 1 includes an operation factor input unit 11 a that receives selection of an operation factor of the fire detector 2. In addition, the liquid crystal display unit 12 includes a statistical information display unit 12a that displays statistical information based on the operation history, but it is preferable that the functions of various switches are provided by a touch panel. The operation history is accumulated in the storage unit 18. The statistical processing of the operation history may be executed by software means on the CPU board 17.

  In a system using an R type or GR type receiver, in order to suppress false alarms, either the receiver 1 or the fire detector 2 accumulates the detection time, and the receiver 1 is careful based on the accumulation, Whether the alarm is issued or interlocked is detected. When an analog detector is used, the detector 2 outputs an analog fire detection signal, so that the receiver 1 determines the alert, alarm, and interlock based on the level.

  Since the present invention pays particular attention to the operating factor of the fire detector 2 at the time of non-fire, the operating factor input unit 11a prepares in advance selection factors for the operating factor at the time of non-fire and selects them appropriately from there. It is desirable to have a configuration that allows input. The operating factor may be input when the fire detector 2 is operated and then the receiver 1 is returned.

  On the other hand, the statistical information display unit 12a is preferably configured to call a statistical information display screen from the management screen of the receiver 1. As the statistical information, for example, for each fire detector 2, the number of operations for each factor, the number of operations for each time zone, and the variation tendency of the number of operations with a week or month as a totaling period can be considered. However, it is not limited to these, and any statistical information may be used. Further, the statistical information is not limited to the numerical display, and may be displayed in a graph.

  With such a configuration, the administrator can grasp the operating factors of the fire detector 2 at the time of non-fire and can take appropriate measures against false alarms. For example, if the number of operations due to cigarette smoke is large, the smoking is prohibited, or if the number of operations due to steam for cooking is large, a ventilation device is added. If the number of activations of the fire detector 2 decreases as a result of such measures, the burden on the administrator is reduced, so that the management can be concentrated.

  Next, the basic operation of the system to which the present invention is applied will be described.

  When the fire detector 2 starts accumulating, the receiver 1 turns on the accumulating lamp. However, when the accumulation of the fire detector 2 continues for a predetermined time or longer, the receiver 1 issues a fire alarm. When the fire detector 2 is restored during accumulation, the receiver 1 turns off the accumulation lamp and returns to the monitoring state.

  When the receiver 1 is in a fire alarm state, the main sound is emitted from the voice unit 14 and “site confirmation”, “fire”, “building, floor, district”, etc. of the occurrence location are displayed on the district display window 13. . At this time, a detailed alarm screen may be displayed on the liquid crystal display unit 12, and the alarm content may be printed out.

  The main sound is, for example, a message such as “Peep, fire detector activated. Please check the scene”. The fire detector 2 that has been restored may re-activate within a predetermined time, but after the second time, even if the message is different, such as “Peep, fire, fire. Please check the scene.” Good.

  Further, the receiver 1 sounds the district sound device 4 according to the preset interlocking registration and operates the interlocking device 6 such as a fire door, a smoke prevention device, and a watering device. Conditions such as which interlocking device 6 is activated may be set individually for each level of attention, alerting, and interlocking. For example, at the attention level, only the district sound device 4 near the generation site is sounded. Moreover, it is good also as a structure which increases the interlocking | linkage level in steps according to elapsed time, ie, increases the interlocking device 6 to operate.

  In response to such a notification operation, the administrator operates the “acoustic stop” switch to temporarily stop the interlocking of the district acoustic device 4 and the like to check the site. To restart the interlocking of the district sound device 4 and the like. The interlocking device 6 can also be manually controlled by a “control operation” switch. After the fire is extinguished, the receiver 1 is returned to the monitoring state by the “recovery” switch. On the other hand, if it is not a fire, measures such as removing the operating factor of the fire detector 2 are taken, and then the recovery switch is operated to return the receiver 1 to the monitoring state.

  FIG. 2 is an example of an alarm screen that is automatically displayed during a notification operation. At the top of the screen, the status message “Sensor has been activated” is displayed. Below that, detailed information on the activated fire sensor 2, ie “building, floor, district”, type, etc. A list is displayed for each sensor 2. And on the right side, the main sound of the receiver 1, the “acoustic stop” switch to stop the sounding of the district acoustic device 4, and the “yes” and “no” switches to select whether or not the fire has occurred after checking the site The switches for calling up the secondary display are arranged.

  FIG. 3 is an example of a fire determination screen, and such a screen is displayed when a fire is selected by selecting whether or not it is a fire. A status message “A sensor has been activated” is displayed at the top of the screen, and detailed information of the activated fire sensor 2 is listed below it. On the right side, a “fire determination” switch for determining a fire, an “individual operation” switch for manually controlling the district sound device 4 and the interlocking device 6 and the like are arranged. When the “fire determination” switch is operated here, not only the sounding stop of the district sound device 4 but also the interlocking stop of all the interlocking devices 6 is released.

  When the receiver 1 is returned to the monitoring state, as a characteristic function of the present invention, an operation factor of the fire detector 2 can be input and accumulated as an operation history. The operating factors are classified into fire / non-fire, and in the case of a fire, “fire” is automatically selected. On the other hand, in the case of a non-fire, it is preferable to select one of the factors assumed in advance. For example, a plurality of options such as “cigarette”, “water vapor”, “mischief”, “air conditioning, etc.”, “construction / test”, etc. may be prepared. Note that the input of the operating factor is not limited to this point, and may be configured as appropriate from the administrator screen. Moreover, you may enable it to input an arbitrary operation factor.

  FIG. 4 shows an example of an operation factor input screen. This screen is displayed when non-fire is selected in the above-described selection of whether or not a fire occurs. A status message “Normally monitoring” is displayed at the top of the screen, and detailed information of the fire detector 2 that has been activated is listed below the status message. And on the right side, “Statistical analysis” switch for statistical analysis of operating factors, “Exit” switch for ending this screen, “Cigarette” to “Construction test” factor selection switch, these processes are executed An “execute” switch or the like is arranged. In this example, since the operation factor of the fire detector 2 is selected by a switch operation, intuitive factor selection is possible.

  Statistical information regarding the operating factor of the fire detector 2 can be displayed at any time by a predetermined operation if the receiver 1 is in a monitoring state. A printout is possible as well. Based on the displayed statistical information, the manager may take appropriate measures to reduce the number of times the fire detector 2 is activated during non-fire.

  FIG. 5 shows an example of a display screen of statistical information, which is displayed when the “statistical analysis” switch on the operation factor input screen is operated or when a predetermined operation is performed on the management screen. . A status message “Normally monitoring” is displayed at the top of the screen, and an operation history for each fire detector 2 and statistical information about the fire detector 2 are displayed below it. This statistical information is the number of operations for each operating factor, but can be switched to other statistical information. On the right side, the “screen print” switch for printing out the screen, the “data erase” switch for deleting one operation history, and the entire operation history for one fire detector 2 are deleted. An “all data erasure” switch for executing the processing, an “execution” switch for executing these processes, and the like are arranged.

  In addition, although the input of the operation factor of the fire detector 2 and the display of the statistical information have been described above, the gas detector 5 can be configured in the same manner and has the same effect. The present invention can also be applied to the receiver 1 to which a sensor other than the fire sensor 1 or the gas sensor 5 is connected.
