Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disaster prevention system, and more particularly to switching of detection sensitivity in a disaster prevention system.
[0002]
[Prior art]
In conventional disaster prevention systems, it is known that the sensitivity of fire detectors and repeaters can be switched. For example, “normal sensitivity” and higher sensitivity “special sensitivity” can be switched in two stages, and “normal sensitivity” is triggered by a signal from outside the disaster prevention system, such as an air conditioning stop signal when unattended. There is a known type that switches from “special sensitivity”.
[0003]
[Problems to be solved by the invention]
However, since the above disaster prevention system is configured so that the sensitivity is switched by an external signal, the disaster prevention system mainly has a function of, for example, performing time management with a receiver and outputting a signal for switching the sensitivity. It wasn't. For this reason, it is highly dependent on an external device that outputs a trigger signal, and when there is no detailed setting function in the external device itself, detailed switching such as day of the week and date / time is difficult. Furthermore, information on the time when the sensitivity is switched could not be confirmed on the disaster prevention system side such as a receiver.
[0004]
On the other hand, for example, Japanese Laid-Open Patent Publication No. 6-20167 discloses that sensitivity can be set for each sensor by operating the display device connected to the disaster prevention monitoring panel, for example, in which the sensitivity is switched on the disaster prevention system side. Is described. However, in this publication, since the setting is made for each sensor, it becomes a serious work when the number of sensors is large. Furthermore, here, there is no function of switching the sensitivity in units of time only that the sensitivity can be changed.
[0005]
Japanese Patent Application Laid-Open No. 5-282777 discloses that sensitivity is switched according to an environment such as the presence or absence of a person for each group as a method for setting a sensitivity of a plurality of sensors collectively. Further, Japanese Patent Application Laid-Open No. 56-132690 describes that the sensitivity of the sensor 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 regarding a specific setting method in the operation unit or the like. Therefore, the operability such as how to set or how to check the setting contents is unknown, and it is applied practically. Hateful.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to enable sensitivity setting and confirmation in a disaster prevention system independently and with fine and simple operations.
[0007]
[Means for Solving the Problems]

For items that can be selected by touching, the frame is shaded and expressed in a three-dimensional manner. Is done. Then, by touching and selecting one function, it jumps to a lower level item connected to that function. The main screen 31a and the sub screen 31b are also provided with explanations of functions in each frame as necessary, so that the operator can operate without hesitation simply by looking at the screen.
However, even if the item is shaded, if it cannot be selected, the character color in the frame is displayed with a method that makes the impression weaker than usual (such as making the color lighter or white) To do.
In addition, in FIG. 3 and the like, there is a case where only a frame is shown for convenience without describing a function name. Further, in the following description, explanations of the functions and the like that are not particularly necessary in the present invention are omitted or simplified.
[0028]
When the power supply is turned on to the disaster prevention system 1 and the whole system starts up, and then the screen 31 of the display unit 30 is touched, first, FIG. 3A is displayed.
3A, 3B, and 4 are display screens of a “screen list”. This screen is composed of three pages. By operating the page changeover switches 32 and 32 provided on the upper right and lower sides of the main screen 31a, FIG. 3 (a) for the first page and FIG. 3 (b) for the second page. ) FIG. 4 on the third page can be sequentially switched.
[0029]
In the “screen list” screen, on the leftmost side of the main screen 31a, functions that are located on the top layer of the hierarchical structure and are independent of each other are shown. Of these, except for “Maintenance Settings”, “1 Alarm”, “2 Abnormal / Fault”, “3 Smoke Prevention Control”, “4 Link Stop”, “5 Training”, and “Screen List” Items can be selected with the tab buttons T1, T2, T3, T4, T5, and T6 of the tab display portion 31c. The selected tab button is displayed in a background color different from the others as in the tab button T6 in FIG.
When the tab button T1 is operated, the screen is switched to an “alarm” screen. On this screen, terminal devices that are outputting various alarms such as a fire and a gas leak are displayed. When the tab button T2 is operated, the screen is switched to the “abnormal / failure” screen, and the abnormal or malfunctioning terminal device is displayed on this screen. When the tab button T3 is operated, the screen is switched to the “smoke prevention control” screen, and a menu screen for remotely controlling the smoke prevention terminal is displayed on this screen. When the tab button T4 is operated, the screen is switched to the “interlocking stop” screen, and a menu screen for stopping various types of interlocking is displayed. When the tab button T5 is operated, the screen is switched to a “training” screen, and a menu screen for receiver operation training and fire simulation is displayed on this screen. Since these “alarm” screen, “abnormality / failure” screen, “smoke prevention control” screen, “interlocking stop” screen, and “training” screen are not the gist of the present invention, description thereof will be omitted.
[0030]
On the sub-screen 31b of the “screen list” screen, a message to the operator is displayed, and a print stop switch A1 and a screen erasure switch A8 are provided.
[0031]
In the display unit 30, switching between normal sensitivity and special sensitivity set for each block as shown in Table 5 can be set for each day of the week on an hourly basis. Hereinafter, this switching setting operation will be described.
First, when the “block sensitivity setting” on the third page of the “screen list” screen shown in FIG. 4 is touched and operated, the display content of the sub screen 31b is changed as shown in FIG. 5, and the password input screen is displayed. Here, the number key B4 of 0 to 9 is operated to input a predetermined password, and when it is correctly input, the determination switch B1 is operated. Thus, by entering the password, it is possible to prevent the sensitivity from being changed carelessly or intentionally. If the clear switch B2 is operated, the entered password is cleared, and the password can be re-entered with the numeric key B4. If the window erase switch B3 is operated, the screen disappears. If you want to display it again, just touch the screen.
[0032]
When the enter switch B1 is operated after entering the password in FIG. 5, the sensitivity block selection screen in FIG. 6 (a) is displayed. 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, an instruction to the operator is displayed on the sub screen 31b.
Here, when the block whose sensitivity is to be changed, for example, the “block 01” button C1 is operated in accordance with the instruction on the sub-screen 31b, the display of the “block 01” button C1 is visually pressed as shown in FIG. 6B. The display is switched to a depressed state and the schedule display switch B5 is switched to an operable state. Next, the schedule display switch B5 is operated.
When the print stop switch B6 on the sub-screen 31b is operated, printing in the printing unit 17 is stopped, and when the return switch B7 is operated, the screen shown in FIG. 5 is returned.
[0033]
When the schedule display switch B5 is operated, the sensitivity switching schedule screen of 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 increments of 1 hour. In addition, instructions and messages to the operator 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, a fire is detected with normal sensitivity for 24 hours every day.
In FIG. 7A, the schedule setting switch B5 cannot be operated. When the screen copy button B8 is operated, the contents displayed on the screen are printed by the printing unit 17.
[0034]
To change the sensitivity setting, operate the day of the week button to be set. Here, for example, the day button D7 on Sunday is operated. As a result, as shown in FIG. 7B, the day of the week button D7 is visually pressed and displayed as being depressed, and the schedule setting switch B5 on the sub-screen 31b is switched to an operable display.
When the schedule setting switch B5 is operated, a sensitivity switching setting screen shown in FIG. 8 is displayed. On this screen, the setting time schedule S7 'for the day of the week (Sunday here) selected in FIG. 7B is displayed on the main screen 31a. The setting time schedule S7 'is displayed as a horizontal bar graph indicating four time zones from 0:00 to 6:00, from 6:00 to 12:00, from 12:00 to 18:00, and from 18:00 to 24:00.
Each horizontal bar graph is displayed in increments of one hour, and is one switching button every hour. For example, by touching the area P1 separated by “05:00” and “06:00” in the top graph, the normal sensitivity displayed in white and the special sensitivity in red are alternately switched on the screen. Can be done.
[0035]
Here, for example, when the range from 0 o'clock to 8 o'clock and 22:00 to 24 o'clock in the time schedule S7 ′ are touched, the range is red as shown in FIG. 8B (FIG. 8B). In the figure, it is changed to a hatched line. After the switch to red, the setting is confirmed by operating the decision switch B9.
Thereafter, when the screen is returned to the sensitivity switching schedule screen by the return switch B7, as shown in FIG. 9, the time zone as set in FIG. 8B is displayed in red (hatched in FIG. 9) indicating the special sensitivity. With this setting, fire will be detected with special sensitivity every day from 0:00 to 8:00 and from 22:00 to 24:00 every day. You can open this screen to check your settings in the future.
As described above, the sensitivity switching screen of the present invention is composed of a sensitivity switching schedule screen and a sensitivity switching setting screen.
Similarly to the blocks 02 to 16 shown in FIG. 6, the sensitivity switching schedule can be set for each day of the week.
[0036]
If it sets as mentioned above, the disaster prevention receiver 10 will output the signal which instruct | indicates switching a sensitivity about the sensor which belongs to the block 01 according to the set schedule under control of CPU11. 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, or the sensor itself or the relay itself. For those who judge fire, the judgment threshold is switched.
When the “sensitivity change setting” item in FIG. 4 is selected, the normal sensitivity and special sensitivity can be changed for each sensor address.
[0037]
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, it is not affected by the level of the function of the external device, etc., and sensitivity can be switched mainly by the disaster prevention system 1 (disaster prevention receiver 10).
In addition, since the setting is switched by an operation on the screen 31, the setting work is simple. Specifically, the sensitivity switching schedule screen is displayed for each day of the week, and the day of week buttons D1 to D7 are operated to display the sensitivity switching setting screen for one day of the week. On the sensitivity switching setting screen, 24 hours are displayed as a horizontal bar graph, and can be switched and set in units of time. Therefore, the sensitivity can be switched for each day of the week and in units of time, and the sensitivity switching can be set finely.
[0038]
In addition, the ROM 13 stores sensitivity that can be set as in the sensitivity table of the table 5 in two stages (normal sensitivity and special sensitivity). The graph has one switching button in one-hour increments, and the normal sensitivity and special sensitivity can be easily switched alternately by simply touching one switching button based on the sensitivity data. Therefore, the normal sensitivity / special sensitivity switching operation is very simple, can be repeated any number of times, and the setting can be easily changed.
Further, 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, it is easy to visually understand both in the switching operation and the confirmation operation. On the sensitivity switching schedule screen, the sensitivity switching schedule for one week can be seen at a glance. Furthermore, the normal sensitivity is displayed in white, 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.
Further, since the sensor can be divided into predetermined blocks and set for each block, the switching setting work can be simplified in this respect.
As described above, in the disaster prevention system 1, in the disaster prevention receiver 10, the sensitivity switching setting of the detector can be switched significantly more easily and visually in comparison with the conventional one, and the confirmation is also very easy. Easy to understand.
In addition, in order to switch the sensitivity, as shown in FIG. 5, since it is necessary to input a password, it is not easily switched, and it is possible to prevent sensitivity switching by a third party other than the administrator.
[0039]
In addition, this invention is not limited to the said embodiment, It can change suitably.
The display and setting method of 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 / set as a calendar in units of one month, or may be displayed / set in units of several weeks or months.
Further, instead of the bar graph type, it may be displayed in a circular or arc shape. In short, it should be designed so that the breaks in the continuous time can be visually recognized.
Sensitivity switching is not limited to block units, and may be switchable for each individual sensor, or the sensitivity of all the sensors may be switched collectively. In this case, for example, a display such as “all terminals” may be added along with a plurality of block displays on the sensitivity block selection screen in FIG.
[0040]
Specific values of “normal sensitivity” and “special sensitivity” can be changed as appropriate, and the special sensitivity may be lower than the normal sensitivity. For example, when a certain room becomes non-smoking from smoking cessation 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, and may be three or more steps.
Furthermore, the fire sensor is not limited to a smoke sensor, and may be a heat sensor, a combined heat / smoke sensor, a flame sensor, or the like.
The table relating to the block sensitivity shown in FIG. 2 may be stored not only in the ROM but also in the RAM, other memory such as an EEPROM built in the disaster prevention receiver, or stored in an external storage medium such as a disk. It may be.
The display unit is not limited to the touch panel system, and may be operated by an input device such as a mouse or a keyboard.
[0041]
