DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an embodiment of an automatic fire alarm system to which the non-fire information processing system of the present invention is applied. In FIG. 1, a transmission line 12 is drawn out from the disaster prevention monitoring board 10 functioning as a receiver toward the caution area. A plurality of on / off type sensors 16 are connected to the transmission line 12 via a repeater 14. In addition, the transmission path 12 has an analog smoke sensor 18 and an analog heat sensor 20 having a relay function.
Is connected.

The relay 14, the analog smoke detector 18, and the analog heat detector 20 receive the polling based on the address designation from the disaster prevention monitoring board 10, and when the self address is determined, the fire detection detected at that time is detected. Information, that is, the relay 14 responds to the fire detection information (fire bit information) from the on / off type sensor 16, and the analog smoke sensor 18 and the analog heat sensor 20 respond to the smoke concentration at that time. And temperature analog data is returned.

Further, the analog smoke sensor 18 and the analog heat sensor 20 are provided with the same fire judging function as the on / off type sensor 16, and when the smoke concentration or the temperature exceeding the threshold value is detected, the fire bit is responded. That is, the analog smoke sensor 18 and the analog heat sensor 20 are multi-signal sensors capable of sending on / off fire bits simultaneously with analog data.

In this embodiment, a sub-receiver 22 having the same reception display and operation functions is connected to the disaster prevention monitoring board 10, and a CRT equipment 24 having a light pen 25 is also provided. Connected. From the top of the disaster prevention monitoring panel 10, a digital display unit 26, a type display unit 28, a liquid crystal display unit 30, an operation unit 32, and a Kanji printer 34 are provided. When the fire prevention monitoring panel 10 receives a fire report from a sensor installed in the warning area, it displays a representative fire on the digital display, and at the same time, displays the type of the reported sensor on the type display 28. Further, the issued sensor number, installation location, etc. are displayed on the liquid crystal display unit 30.

At the same time as the fire is received, a message "Please check the site" is displayed on the liquid crystal display section 30 in the management room. Upon receiving the message prompting confirmation of the site when the fire is received, the administrator visits the site and confirms the fire, and then performs a fire assertion operation on the operation unit 32. When the main unit rings, the district bell rings, emergency broadcast, etc. Fire assertion processing is performed.

On the other hand, when the site is confirmed to be non-fire, the operation input indicating the non-fire is performed, and then the restoration operation is performed to restore the normal monitoring state. In addition to this non-fire input operation, in the present invention, the cause of the non-fire determined by the site confirmation is input. The non-fire input may be performed by using the operation unit 32 of the disaster prevention monitoring panel 10 or by using the light pen 25 on the work screen of the CRT equipment 24.

For the disaster prevention monitoring board 10, a non-fire processing unit 36 is provided for the non-fire information processing of the present invention. The non-fire processing unit 36 includes an MPU 38, an interface 40 for the disaster prevention monitoring board 10, a database 42 storing data on non-fire, a CRT 44, a printer 46, a touch pen or a mouse, and the like. Such a non-fire treatment unit 36 can be realized by a personal computer level or workstation level computer device.

FIG. 2 illustrates the function of the non-fire treatment unit 36 of FIG. As the functions realized by the MPU 38,
A memory confirmation unit 2, a non-fire determination notification unit 6 and a countermeasure determination notification unit 7 are provided. The non-fire data input unit 1 inputs information about non-fire and data indicating the cause to the memory confirmation unit 2. In response to this input, the storage confirmation unit 2 creates the non-fire data table 3 on the database 42.

FIG. 3 is an example of the non-fire data table 3 created on the database 42 of FIG. In this non-fire data table, the type / type of sensor is taken as an example as the first classification item. For this classification item, in addition to the type / type of detector, create a non-fire data table for device information such as repeater distributed processing panel or area information such as detector address, area name, building name, room name, etc. You can also

The non-fire data table in which the types / types of sensors shown in FIG. 3 are used as classification items can be said to be the most basic table. Following the type / type that is the classification item, there are provided items of occurrence time, end time, cause, and site confirmer. Regarding the occurrence time and the end time, for example, time data can be automatically input from the fire reception and the recovery operation in the disaster prevention reception panel 10.

As for the cause, the cause of the non-fire alarm judged by the site confirmation when the fire is received is input. The following four input items are prepared for the cause of this non-fire alarm, for example. Tobacco Water vapor Dust Artificial unknown In this case, the cause of the non-fire alarm is "water vapor" for sensor A001. The sensor A100 is "cigarette". The last field confirmer item stores the name of the confirmer who confirmed the site for the non-fire alarm. The cause of this and the person who confirmed the site should be manually entered (bar code, magnetic card, voice recognition, etc.).

Referring again to FIG. 2, the memory confirmation unit 2
In addition to storing the necessary non-fire data in the non-fire data table 3, when the non-fire data input section 1 receives a confirmation input of the non-fire data, the non-fire data table 3 is stored by the designated sensor number. It retrieves and reads the corresponding non-fire data and displays it on the display unit 8. The display unit 8 is shown in FIG.
0 may be the CRT 44 provided in the non-fire treatment unit 36, the display transferred to the liquid crystal display unit 30 of the disaster prevention monitoring panel 10, or the transfer display to the CRT equipment 24.

The non-fire judgment notifying section 6 is activated when new storage processing of non-fire data is performed by the storage confirming section 2, and in the non-fire data table 3, the non-fire determination notification section 6 which exceeds a predetermined threshold value is selected. The sensor having the number of fire reports is judged, and the judgment result is displayed on the display unit 8. As a result, it is possible to know the sensor that frequently generates non-fire alarms and take countermeasures to reduce the non-fire alarms.

For example, if the detector judged to have generated a large number of non-fire alarms is a photoelectric smoke detector, a false alarm due to dust adherence may occur, so cleaning and inspection of the detector should be performed. become. That is, the notification information from the non-fire determination notification unit 6 can be utilized as information for maintenance and inspection. Furthermore, the countermeasure determination notification unit 7 is a non-fire determination notification unit 6
With respect to the sensor for which the number of non-fire information exceeding the threshold value has been determined in step 1, a comparative determination for reducing the non-fire information is performed, and countermeasures are output to the display unit 8 to notify. To determine this countermeasure, the database 42 stores the building-specific data table 4
And the common reference data table 5 are stored in advance.

FIG. 4 is an example of the building-specific data table 4. The building-specific data table 4 is similar to the non-fire report data table of FIG.
By type, all the sensors installed in the building where the automatic fire equipment of Fig. 1 is installed are registered in the classification item. This example illustrates two sensors at addresses A001 and A100.

Subsequent to the classification item of type / classification, there are provided items such as room usage, ceiling height, fire load, usage and environmental condition. The purpose of the room is, for example, sensor A00
1 is a cooking room, and sensor A100 is a conference room. Ceiling height is one parameter that indicates the size of the sensor installation location. Therefore, in addition to the ceiling height, information indicating other sizes may be used.

The fire load indicates how much the combustible material is, for example, in terms of wood, and the larger the number, the greater the risk of a fire.
The following usages indicate, for example, that there is fire in the cooking room and that there is no fire in the conference room. The usage information also includes attribute information such as whether a person is in the room or not.

As the last environmental condition, the smoke density, which is a physical change subject to fire monitoring, the condition of temperature, and the conditions such as air flow and dew condensation related to fire detection are stored. In this example, the environmental condition of "smoke stays in the normal state" is stored for the cooking chamber of the detector A001, and the environmental condition of "smoking smoke is stagnant" is stored for the conference room of the sensor A100. .

This building-specific data table stores each item at the time of equipment start-up when the disaster prevention monitoring board 10 is installed in the building. However, if the purpose or usage of the room is changed after that, it is changed. Need to update the table with the contents of. FIG. 5 is an example of the common reference data table 5 provided in the database 42 of FIG. This common standard data table is created in accordance with the equipment standards defined by the Fire Service Law. In the case of FIG. 5, the use of the room is classified as a classification item, and information about the usage, the environmental condition, and an appropriate sensor according to the legal standard is registered. For example, the use of the room is stored as if there is fire in the cooking room,
Under normal environmental conditions, smoke is accumulated, and for such a situation, an appropriate sensor based on legal standards is a constant temperature type 1 or a constant temperature type special sensor. In addition, the usage of the room is that there is no fire in the meeting room, and the smoke of the smoking is accumulated in the environmental condition. In this case, there are two or three kinds of smoke detectors as appropriate detectors. .

FIG. 6 shows the types of adaptive sensors and some of the types for the installation locations of the Fire Defense Law regulations that are the basis for creating the common reference table of FIG. FIG. 7 is also the same as FIG.
Shows the type of adaptive sensor for the installation location of the Fire Defense Law regulations that is the basis for the creation of the common reference data table of.
Referring again to FIG. 2, the countermeasure decision notifying unit 7 uses the building-specific data table 4 and the common reference table 5 as shown in FIGS. 4 and 5, and the fire decision notifying unit 6 causes non-fire exceeding the threshold value. The non-fire data corresponding to the number of times the information has been sent is read from the non-fire data table 3 and compared and judged to determine whether the currently installed sensor is appropriate. If the installed sensor is unsuitable, the display unit 8 provides guidance for instructing the appropriate sensor type and sensitivity.
I will do it against.

FIG. 8 is an outline of fire monitoring processing in the disaster prevention monitoring board 10 of FIG. When a fire alarm is determined in step S1, the process proceeds to step S2 to check whether there is a fire or no fire. In this determination, when the administrator visits the site and confirms the fire, if the user inputs the fire assertion, the process proceeds to the fire assertion processing in step S3. On the other hand, in the case of non-fire, if non-fire input processing is performed, the process proceeds to non-fire handling processing in step S4, and non-fire handling processing shown in detail in FIG. 9 is performed.

In the non-fire handling process of FIG. 9, first, step S
In 1, enter the cause of non-fire. This input can be made by clicking on any one of the five causes: cigarette, water vapor, dust, artificial, and unknown, as shown in the work screen 46 on the right side. Of course, other sensor numbers,
The occurrence time and end time are automatically input and transferred when the cause of non-fire is entered.

Next, in step S2, the name of the site confirmer is input as shown on the work screen 48 on the left side. When the name of the site confirmer is input, in step S3, the non-fire data accumulation process for the database is performed, for example, as shown in the non-fire data table of FIG. Next, in step S4, the number of non-fires is calculated by searching for the sensor number that has become the current non-fire information in the non-fire data table 3, and it is determined whether the number of non-fires has exceeded a predetermined threshold value. If the threshold is not exceeded, the process returns to the main routine of FIG.

If the number of non-fires exceeds the threshold,
In step S5, the non-fire accumulated data is notified.
This notification of the non-fire accumulated data is, as shown in the notification screen 50a, as the data by sensor, the date and time of occurrence, the number of occurrences,
The cause of occurrence may be displayed, or the number of occurrences, the sensor address, and the date and time of occurrence may be displayed as the cause-specific data as in the display screen 50b.

Next, in step S6, the non-fire accumulated data and the table data of the prestored building-specific data and the reference common data are compared and analyzed, and the non-fire count of the sensor whose detector exceeds the threshold value is detected. The countermeasure for reducing the fire alarm is determined, and the countermeasure is announced in step S7. As shown in the display screen 52 on the left side, this notification indicates that, for example, when an appropriate sensor is not installed even though the purpose of the room is a cooking room, the constant temperature type 1 which is an appropriate sensor is used. Guidance is displayed to encourage changes to the species.

FIG. 10 shows details of the countermeasure determining process in step S6 of FIG. First, in step S1, the cause of non-fire is compared with the environmental condition of the common reference data. For example, the cause of the non-fire alarm of the detector A001 of FIG. 3 is water vapor, and the environmental state of “smoke stays in normal condition” is recognized by comparison with the environmental state of the common reference data table of FIG. Next, in step S2, referring to the building-specific data table of FIG. 4, it is recognized that the room of the sensor A001 is "cooking room", and the room of the common reference data of FIG. Compare with "room". Next, the usage "with fire" of the sensor A001 in the sensor-specific data table of FIG. 4 will be compared with the usage of the common reference data table of FIG.

By comparing the data tables with each other as described above, the type and sensitivity of the sensor A001 which is a non-fire alarm and is suitable for the installation location, usage and environmental conditions are specified, and Installed sensor A001
If there is a mismatch in the type and sensitivity of the sensor determined to be appropriate, guidance is displayed in step S4 regarding the type and sensitivity of the appropriate sensor.

In the typical example of the countermeasure determination process of FIG. 10, the purpose of the room is changed from the conference room to the cooking room after the building is completed, and the building-specific data table of FIG. 4 is rewritten. However, this is the case when the detector itself has been installed from the beginning. In such a case, non-fire information frequently occurs when changing from the conference room to the cooking room, and the usage of the room may be changed through the judgment process of the countermeasure when the number of non-fire information exceeds the threshold. Regardless, the appropriate sensor is not installed, and the guidance display will be displayed to the effect that the appropriate sensor will be installed according to the changed application.

In addition, by comparing the building-specific data with the common reference data before and after the building is completed, if the terminal installation is inappropriate, the terminal data is displayed and the optimum terminal is announced. You may display the guidance that the optimal terminal should be installed. In the embodiment shown in FIG. 1, the non-fire alarm processing unit 36 is provided as an external device of the disaster prevention monitoring board 10, but the function of the non-fire processing unit 36 may be incorporated in the disaster prevention monitoring board 10 itself. Good. When provided as an external device, the non-fire treatment unit 36 may not be a dedicated device but may utilize the function of the host computer system or the server client system already installed in the building. Furthermore, the contents of the database 42 of the non-fire processing unit 36 may be centrally collected and managed using a communication line.

[0039]

As described above, according to the present invention, when there is a non-fire alarm, if the cause of the non-fire alarm is input to the receiver, the non-fire alarm occurrence time for the sensor command and The cause, the number of times, etc. are automatically stored in the database, and the information regarding the non-fire alarm can be read and confirmed at any time as needed.

Further, when the number of non-fire alarms in one sensor exceeds a certain number, appropriate maintenance measures can be taken by issuing a display or alarm to that effect. Furthermore, as a common standard data based on the building-specific data and legal standards for fire monitoring, the cause of accumulated non-fire alarms is compared and analyzed, and countermeasures such as guidance of the optimum sensor to reduce non-fire alarms are announced. The non-fire alarm can be effectively reduced.
