Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a disaster prevention system, and more particularly to switching of detection sensitivity in a disaster prevention system.

[0002]

2. Description of the Related Art There is known a conventional disaster prevention system in which the sensitivity of a fire detector or a repeater can be switched. For example, "normal sensitivity" and "special sensitivity" with higher sensitivity
There is known a type in which the signal is switched from "normal sensitivity" to "special sensitivity" by using a signal from outside the disaster prevention system such as an air-conditioning stop signal when the vehicle becomes unmanned as a trigger.

[0003]

However, since the above-described disaster prevention system is configured so that the sensitivity is switched by an external signal, the sensitivity is switched by performing time management by a disaster prevention system, for example, a receiver. It did not have a function of outputting a signal. Therefore, it largely depends on an external device that outputs a signal serving as a trigger, and when there is no detailed setting function in the external device itself, it is difficult to perform detailed switching such as a day of the week and a date and time. Furthermore, information on the time at which the sensitivity is switched cannot be confirmed on the disaster prevention system side such as a receiver.

On the other hand, as an example of switching the sensitivity on the disaster prevention system side, Japanese Patent Laid-Open No. 6-20167, for example, discloses that the sensitivity can be set for each sensor by operating the screen of a display device connected to the disaster prevention monitoring panel. Is described. However, in this publication, the setting is performed for each of the sensors, so that when the number of the sensors is large, it becomes a serious operation. Furthermore, here, only the sensitivity can be changed, but there is no function of switching the sensitivity in units of time.

As a method of setting the sensitivity of a plurality of sensors collectively, Japanese Patent Application Laid-Open No. 5-282577 describes that the sensitivity is switched for each group according to the environment such as the presence or absence of a human. Further, JP-A-56-1326
Japanese Patent Publication No. 90 describes that the sensitivity of the detector is switched by a timer signal for all or for each fire detection system such as for each floor. In these inventions, there is no description about a specific setting method in the operation unit or the like. Therefore, it is unclear how to make the setting or how to confirm the setting content. Hateful.

An object of the present invention is to provide a disaster prevention system,
It is an object of the present invention to enable setting and checking of sensitivity switching by a detailed and simple operation.

[0007]

Means for Solving the Problems To solve the above-mentioned problems, the invention according to claim 1 comprises a plurality of detectors (fire detectors 3a, 3a...) As shown in FIGS. Is connected, and a disaster prevention receiver (10) including a display unit (30) is provided. The disaster prevention receiver is configured to execute a predetermined function based on an operation on a screen (screen 31) of the display unit. In the disaster prevention system (1), a sensitivity switching screen (sensitivity switching schedule screen, sensitivity switching setting screen) for switching the sensitivity of the sensor by a predetermined operation is displayed on the screen.

According to the first aspect of the present invention, the sensitivity of the sensor can be switched by a predetermined operation on the sensitivity switching screen displayed on the display unit of the disaster prevention receiver constituting the disaster prevention system. Therefore, since the switching is not performed by the external input signal, the sensitivity can be independently switched on the disaster prevention system side without being affected by the function of the external device. In addition, since it switches by operation on the screen,
Setting work is easy. Here, the sensitivity switching screen may include not only one type of screen display but also a plurality of pages, or may have a multilayer structure, and may be configured to switch the sensitivity while switching the screen. .
Also, the predetermined operation on the screen for sensitivity switching is
For example, touching the screen, giving an instruction with a pointing device such as a mouse, or inputting using a keyboard can be cited. Further, "switching the sensitivity of the sensor" means that the disaster prevention receiver switches the internal sensitivity information when making a fire judgment based on the data returned from the analog sensor, or the sensor itself or the relay itself fires the fire. Switching of the threshold value for the judgment is given.

According to a second aspect of the present invention, in the disaster prevention system according to the first aspect, the disaster prevention receiver includes storage means (ROM 13) for storing settable sensitivities in multiple stages.
Switching of the sensitivity on the sensitivity switching screen is performed by switching from one sensitivity of the multi-stage sensitivity to another sensitivity. According to the second aspect of the present invention, since the sensitivity is changed by switching from one of the multi-stage sensitivities stored in the storage means to another, the specific numbers are individually input. It is easier to switch than the setting method of doing.

[0010] The invention described in claim 3 is the second invention.
In the disaster prevention system described in 1 above, the time at which the sensitivity is switched is set on the sensitivity switching screen. According to the third aspect, since the time at which the sensitivity is switched is set, it is possible to set, for example, the sensitivity is switched at a predetermined time every day, which is practical.

And According to the invention described in claim 6, since the schedule is displayed based on the day of the week, the setting of the sensitivity switching can be performed for each day of the week. In the case of the day of the week, sensitivity switching can be set based on the situation of each day of the week throughout the year, regardless of the date, and the convenience is high. For example, in a disaster prevention system for a building in which a company whose tenants are a business day on a weekday and a weekend on a Monday to Friday is a business day, different settings may be made on weekdays and weekends.

According to a seventh aspect of the present invention, in the disaster prevention system according to any one of the fourth to sixth aspects, the schedule is displayed based on time, and switching of sensitivity can be set based on time. It is characterized by. According to the seventh aspect of the present invention, the schedule is displayed based on time, so that detailed settings can be made based on the situation for each time. For example, if a building has no people at night, increase the sensitivity at night compared to daytime. In particular, in the case of subordination of claim 6, since the switching of the sensitivity can be set based on the time for each day of the week, more detailed setting is possible. Here, “based on time” may be configured to be set at predetermined time intervals, or may be configured to switch the sensitivity at an arbitrary time.

According to an eighth aspect of the present invention, in the disaster prevention system according to the seventh aspect, the time is graphically displayed. According to the invention described in claim 8, the time is displayed by the graph, so that it is easy to understand visually.

According to a ninth aspect of the present invention, in the disaster prevention system according to the eighth aspect, the graph is divided into predetermined time units, and the sensitivity can be switched for each division. According to the ninth aspect of the present invention, the sensitivity can be switched for each section divided in a predetermined time unit, so that the switching operation is further facilitated. Here, the time width as one unit of the division is not limited at all, and may be set as appropriate.

The block names in the disaster prevention system 10 are displayed on the main screen 31a, and the display of each block name is a selection button. In addition, instructions to the worker are displayed on the sub screen 31b. Here, in accordance with the instruction on the sub-screen 31b, the block whose sensitivity is to be changed, for example, “Block 0”
When the "1" button C1 is operated, the display of the "block 01" button C1 is visually pressed and switched to a depressed display as shown in FIG. 6B, and the schedule display switch B5 is operable. Switch to state. Next, the schedule display switch B5 is operated.
When the print stop switch B6 on the sub screen 31b is operated, the printing in the printing unit 17 is stopped, and when the return switch B7 is operated, the screen returns to the screen of FIG.

When the schedule display switch B5 is operated, a sensitivity switching schedule screen shown in FIG. 7A is displayed. Day buttons D1 to D7 are provided on the left side of the main screen 31a, and time schedules S1 to S7 from 0:00 to 24:00 are displayed beside each button. The time schedules S1 to S7 are displayed as horizontal bar graphs in units of one hour. In addition, instructions and messages to the worker are displayed on the sub screen 31b. As shown in this message, the normal sensitivity is displayed in white, and the special sensitivity is displayed in red. The display in FIG. 7A is in an initial setting state, and all time schedules S1 to S7 are displayed in white from Monday to Sunday. That is, in block 01, it means that a fire is detected with normal sensitivity for 24 hours every day. FIG.
In (a), the schedule setting switch B5 cannot be operated. Screen copy button B
When the user operates the button 8, the content displayed on this screen is printed by the printing unit 17.

To change the sensitivity setting, the user operates the day button of the day on which the setting is to be made. Here, for example, the day button D7 of Sunday is operated. As a result, as shown in FIG. 7B, the day of the week button D7 is visually pressed and displayed as if it is depressed, and the display is switched to a display in which the schedule setting switch B5 on the sub screen 31b can be operated.
When the schedule setting switch B5 is operated, a sensitivity switching setting screen shown in FIG. 8 is displayed. On this screen, a time schedule S7 'for setting the day of the week (here, Sunday) selected in FIG. 7B is displayed on the main screen 31a. The setting time schedule S7 'is from 0:00 to 6
Hours, 6:00 to 12:00, 12:00 to 18:00, and 18:00 to 24:00 are displayed as horizontal bar graphs. Each horizontal bar graph is displayed in units of one hour, and one switching button is provided every one hour. For example, the area P divided by “05:00” and “06:00” in the top graph
By touching 1, the normal sensitivity displayed in white on the screen and the special sensitivity displayed in red can be alternately switched.

Here, for example, the time schedule S7 '
When the user touches the range from 0:00 to 8:00 and from 22:00 to 24:00 in, the range changes to red (shown by oblique lines in FIG. 8B) as shown in FIG. 8B. . After the display is switched to red, the setting is confirmed by operating the enter switch B9. Thereafter, when the screen returns to the sensitivity switching schedule screen by the return switch B7, as shown in FIG.
The time zone as set in (b) shows a special sensitivity in red (FIG. 9
Is displayed with oblique lines). With this setting, a fire is detected with special sensitivity every day from 0:00 to 8:00 and from 22:00 to 24:00 every Sunday. To confirm the settings in the future, open this screen. As described above, the sensitivity switching screen of the present invention includes the sensitivity switching schedule screen and the sensitivity switching setting screen. Blocks 02 to 1 shown in FIG.
As for 6, the sensitivity switching schedule can be set for each day of the week in the same manner as described above.

When set as described above, the disaster prevention receiver 10
Outputs a signal instructing to switch the sensitivities of the sensors belonging to the block 01 according to the set schedule under the control of the CPU 11. Here, "switching the sensitivity of the sensor" means switching the internal sensitivity information when the disaster prevention receiver 10 itself makes a fire judgment based on the return data from the analog sensor, and also detects the sensor itself or the repeater itself. Is to switch the judgment threshold for those that judge a fire. When the item “sensitivity change setting” in FIG. 4 is selected, the normal sensitivity and the special sensitivity can be changed for each address of each sensor.

According to the disaster prevention system 1 described above, the sensitivity can be switched on the screen of the display unit 30 of the disaster prevention receiver 10. Therefore, the disaster prevention system 1 (disaster prevention receiver 1) is not affected by the degree of the function of the external device.
0) can be mainly used to switch the sensitivity. Further, the setting operation is simple because the switching is performed by the operation on the screen 31. Specifically, the sensitivity switching schedule screen is displayed as a schedule for each day of the week, and by operating the day of the week buttons D1 to D7, a sensitivity switching setting screen for one day of the week is displayed. Then, on the sensitivity switching setting screen, 24 hours are displayed as a horizontal bar graph, and switching can be set in units of time. Therefore, the sensitivity can be switched for each day of the week and for each hour, and the sensitivity switching can be finely set.

In addition, the ROM 13 has two levels of sensitivity that can be set as in the sensitivity table of Table 5 (normal sensitivity
(Special sensitivity). In the graph, one switching button is provided at intervals of one hour, and the normal sensitivity and the special sensitivity can be easily switched alternately simply by touching one switching button based on the sensitivity data. Therefore, the switching operation between the normal sensitivity and the special sensitivity is very easy, can be repeated any number of times, and the setting can be easily changed. In addition, since both the sensitivity switching schedule screen and the sensitivity switching setting screen are displayed as horizontal bar graphs for each hour with respect to time, both the switching work and the confirmation work are visually easy to understand. On the sensitivity switching schedule screen, the schedule of sensitivity switching on a weekly basis can be understood at a glance. Furthermore, the normal sensitivity is displayed in white and the special sensitivity is displayed in red, and it is clear which sensitivity is set for an arbitrary time on a certain day of the week, so that it can be easily confirmed. In addition, since the sensors can be divided into predetermined blocks and can be set collectively for each block, the switching setting work can be simplified also in that respect. As described above, in the disaster prevention system 1, in the disaster prevention receiver 10, the switching setting of the sensitivity of the detector can be significantly simplified and visually easily understood as compared with the related art, and the confirmation is also very easy. It is easy to understand. In addition, as shown in FIG. 5, in order to switch the sensitivity, it is necessary to input a password, so that the switching is not easily performed, and the switching of the sensitivity by a third party other than the administrator can be prevented.

It should be noted that the present invention is not limited to the above embodiment, but can be changed as appropriate. The method of displaying and setting the time schedule is not limited to displaying one week as a day of the week shown in FIGS. For example, the date may be specified and displayed and set like a calendar in units of one month, or may be displayed and set in units of weeks or months. Further, instead of the bar graph type, it may be displayed in a circular or arc shape. In short, it is only necessary that the design be made so that the breaks in the continuous time can be visually recognized. The sensitivity switching is not limited to a block unit, and may be switchable for each individual sensor, or may be such that the sensitivities of all the sensors are switched collectively. In this case, for example, a display such as “all terminals” may be added along with the plurality of block displays on the sensitivity block selection screen in FIG. 6A.

The specific values of "normal sensitivity" and "special sensitivity" can be changed as appropriate, and the sensitivity of the special sensitivity may be lower than the normal sensitivity. For example, when a certain room is allowed to smoke from non-smoking due to a time limit, the sensitivity may be specifically reduced only during the smoking time. In addition, the sensitivity switching is not limited to two steps but may be three or more steps. Furthermore, fire detectors are not limited to smoke detectors.
It may be a combined smoke detector, a flame detector, or the like. The table regarding the block sensitivity shown in FIG. 2 may be stored not only in the ROM but also in the RAM, may be stored in a memory such as an EEPROM built in the disaster prevention receiver, or may be stored in an external storage medium such as a disk. May be. The display unit is not limited to the touch panel type, and may be operated by an input device such as a mouse or a keyboard.

According to the first aspect of the present invention, the sensitivity of the sensor can be switched by a predetermined operation on the sensitivity switching screen displayed on the display unit of the disaster prevention receiver constituting the disaster prevention system. Therefore, since the switching is not performed by the external input signal, the sensitivity can be independently switched on the disaster prevention system side without being affected by the function of the external device. Further, since the switching is performed by the operation on the screen, the setting operation is easy.

According to the second aspect of the present invention, the sensitivity is:
Since this is performed by switching from one sensitivity among the multi-stage sensitivities stored in the storage means to another sensitivity, the switching can be performed more easily than the setting method of inputting specific numbers individually. According to the third aspect, since the time at which the sensitivity is switched is set, it is possible to set, for example, the sensitivity is switched at a predetermined time every day, which is practical.

According to the fourth aspect of the present invention, since the sensitivity can be switched based on the schedule, setting for a plurality of days can be performed at once, which is convenient. Claim 5
According to the invention described in (1), a list of schedules is displayed on the sensitivity switching screen, so that it is easy to confirm the schedule setting status. According to the invention described in claim 6, since the schedule is displayed based on the day of the week, the setting of the sensitivity switching can be performed for each day of the week. In the case of the day of the week, sensitivity switching can be set based on the situation of each day of the week throughout the year, regardless of the date, and the convenience is high.

According to the seventh aspect of the present invention, since the schedule is displayed based on time, it is possible to make detailed settings based on the situation at each time. For example, if a building has no people at night, increase the sensitivity at night compared to daytime. In particular, in the case of subordination of claim 6, since the switching of the sensitivity can be set based on the time for each day of the week, more detailed setting is possible. According to the invention described in claim 8, the time is displayed by the graph, so that it is easy to understand visually.

According to the ninth aspect of the present invention, the sensitivity can be switched for each section divided in a predetermined time unit, so that the switching operation is further facilitated.

According to the tenth and eleventh aspects of the present invention, since the objects whose sensitivities have been switched are displayed differently from those before the switching, it can be seen at a glance that the sensitivities have been switched.

According to the twelfth aspect of the present invention, it is necessary to input a password in order to switch the sensitivity. Therefore, the switching cannot be easily performed, and the switching of the sensitivity by a third party other than the administrator can be prevented. it can. According to the thirteenth aspect, since the sensitivity can be switched in units of blocks, the sensitivity can be switched collectively for a plurality of sensors belonging to one block, and the setting operation is further facilitated.
