Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a smoke sensor, a heat sensor,
Fire receiver that consists of multiple lines connected to fire detection devices such as transmitters and detects fire detection status of smoke detectors, heat detectors, transmitters, etc. and performs fire alarm processing Regarding

[0002]

2. Description of the Related Art In a conventional fire receiver, when an operation test of only the fire receiver itself is performed, after a line to be tested is selected by a line selection switch consisting of one pushbutton switch and a fire is reported, There is a method of operating the line selection switch to select the next line in order, and finally operating the recovery switch to restore all lines after the fire test from all lines is completed. In this case, when a fire alarm is issued, if the circuit of the fire receiver is normal, the district light (equipped with the fire receiver) corresponding to the line is turned on.

However, when the fire receiver itself is tested at the same time that the alarm equipment such as the area bell is operating normally (hereinafter, both are collectively referred to as "fire test"), If you did the test by the method, with the line that was fire-tested now being fired,
In order to move to the next fire circuit test, as the fire test progresses, not only the district lights continue to light up, but also the alarm equipment such as the area bell continues to operate at the same time, and which alarm equipment is currently operating. Since it is difficult to grasp, in this case, in general, select a line with the line selection switch, operate the test switch to report the fire, and then operate the recovery switch to recover the line After turning off the district lights, stopping the district bell, etc.), select the next line with the line selection switch and test the line one by one.

Many of the above-mentioned line selection switches are push-button switches, and each time the switch is pressed once, the line one level higher (in this specification, for example, the line higher than the line 1 is connected to the line 2). And the upper line of line 2 is line 3. Conversely, for example, the lower line of line 3 is line 2, line 2
The lower line of is called line 1. ) Is to be selected.

[0005]

In the above fire test, the line is not selected after the fire test is completed. Because the fire test activates the alarm equipment such as district lights and district bells that correspond to the line,
If you leave the line selected as it is after the fire test, if you perform another test or if a fire detection device actually detects a fire, an alarm such as the district light or district bell will be issued. This is because it is not possible to distinguish whether the equipment is operating by a fire test, another test, or an actual fire alarm.

However, in the conventional fire receiver, in order to prevent forgetting to return to the state where the line is not selected after the fire test, when the fire recovery switch is operated, the line selected state is released. , When conducting fire tests on a plurality of lines in sequence, for example, line 1
If you select 0, you have to press the line selection switch 10 times, so you have to press the line selection switch many times to select the next line. Indeed, the number of operations increases,
The problem is that it takes time to test multiple lines.

In order to solve the above problem, it is conceivable to use a line selection switch for inputting each of the second digit and the first digit of the line number, or to similarly set each digit with a plurality of rotary switches. However, there is a problem that it is necessary to provide a plurality of switches and a large installation space is required.

The present invention has been made in view of the above problems, and an object thereof is to make it possible to easily and quickly select a line in a fire test by using one line selection switch. is there.

Fire test means for performing an operation test of the line, one line selection switch, and control means for receiving a manipulation signal from the line selection switch and selecting a line to be put into a pseudo fire detection state are selected. In a fire receiver comprising at least display means for displaying a line, a test switch for operating the fire test means, and a restoration switch for restoring the line operated by the fire test means, the control means comprising: The operation of the restoration switch is detected, and the next line is automatically selected.

Further, the present invention according to claim 3 is the method according to any one of claims 1 and 2, wherein an operation signal is generated when the line selection switch is rotated one step in one direction, and It is characterized in that it is constituted by a rotary encoder capable of rotating one rotation or more in one direction, and the control means selects one upper or lower line when the operation signal is detected.

Further, according to the present invention as defined in claim 4, in any one of claims 1 and 2, the first operation signal is generated when the line selection switch is rotated one step in one direction. And if it rotates one step in the other direction, the second

[0014]

According to the present invention of claim 1 having the above-mentioned structure, the line selected at that time is retained even if the restoration switch is operated.

Further, according to the invention of claim 2, the next line is automatically selected when the fire is restored, so that the next line can be operated without operating the line selection switch.

Further, according to the present invention of claims 3 to 4, the next higher or lower line is selected each time the rotary encoder, which is a line selection switch, is rotated by one step. If the number of lines increases, the rotary encoder can be rotated one revolution or more in the same direction, and the upper or lower line can be selected, so the line can be selected with only one line selection switch regardless of the number of lines. For example, when the line selection switch is composed of a rotary switch, the line cannot be rotated more than one rotation, so that it is not possible to select a higher or lower line. Further, according to the present invention of claim 4, Rotate the rotary encoder in any direction so that you can quickly select the line and select the upper or lower line as appropriate. That.

Further, according to the present invention of claim 5, if the user forgets to return the line selection switch despite the completion of the fire test, the line is not automatically selected after a predetermined time.

[0018]

The present invention will be described below based on an embodiment thereof. 1 to FIG. 8 relate to the first and second embodiments of the present invention,
FIG. 3 relates particularly to the first embodiment, and FIGS.
Particularly relates to the second embodiment.

First, a first embodiment according to the present invention will be described. Fig. 2 shows the fire receiver 1 and the x number of fire detectors connected to the fire receiver 1 (x is the total number of lines)
3 is a functional block diagram showing an embodiment of a fire monitoring system configured by connecting lines L1 to Lx of FIG. FIG. 3 is an external view showing the operation panel section of the fire receiver.

The fire detecting device includes, for example, a smoke detector 10, a heat detector 11, a transmitter 12, a flame detector 13, and a separate smoke detector 14 (14b is a light emitting portion and 14a is a light receiving portion).
and so on.

In the fire receiver 1 of this embodiment, the line Ln (n is an arbitrary number; hereinafter simply referred to as "line Ln") selected in the fire test is artificially set to the fire detection state and the operation of the line is performed. A plurality of fire test circuits 5 for testing, a plurality of fire detection circuits 6 for detecting a fire detection state of the line Ln, a line Ln
A plurality of wire breakage detection circuits 7 for detecting wire breakage abnormality are provided for each of the lines L1 to Lx. The fire test circuit 5 creates a pseudo fire state of the line Ln by short-circuiting the contacts of the connected line Ln.

The fire receiver 1 further includes a line selection switch SW1 which is a push button switch for selecting any of the lines L1 to Lx to be tested by the fire test circuit 5, and a storage means 3 such as a volatile memory (RAM). And a display means 4 such as a liquid crystal panel for displaying characters such as "line selection n" to indicate the currently selected line Ln, and a test switch SW2 for operating the fire test circuit 5 of the selected line Ln. And the line L operated by the fire test circuit 5
Recovery switch SW3 for recovering n and C for controlling each part
And a control means 2 such as a PU (central processing unit). The line selection switch SW1 is used to select a line to be tested when performing a fire test, or to select a line to be operated when operating a smoke proof / exhaust device.

The control means 2 outputs the information of the selected line Ln to the display means 4, and the display means 4 displays the information on a part of the 7-segment portion 4a shown in FIG. . FIG. 4 is a diagram showing the contents displayed on the 7-segment portion 4a of the display means 4 each time the line selection switch SW1 is operated. The 7-segment portion 4a is displayed every time the line selection switch SW1 is operated. Changes as shown in FIG.

The display means 4 is not limited to a character display such as a liquid crystal panel, but may be a 7-segment LED, an LED or a district light of the corresponding line that blinks or lights, or a combination thereof. It may be displayed by. (In the embodiment, description will be made by taking a case of displaying characters such as a liquid crystal panel as an example.) The fire test circuit 5 is one, and is connected to each of the lines L1 to Lx by the line selection switch SW1. You may do it.

FIG. 1 is a flow chart showing the operation of the fire receiver. Here, the operation of the fire receiver will be described with reference to FIG. (S1) Normally, n = 0 and the line is not selected. Nothing is displayed on the 7-segment portion 4a of the display means 4. Because no line is selected, the district lights (not shown) will not light or blink, and the district bell (not shown) will not work. (S2 to S4) When the line selection switch SW1 is operated, the control means 2 causes n to be the next higher number (n = n +).
Update to 1), and accordingly, the fire test circuit 5 of the line Ln one level above is selected and put into the operation standby state. Storage means 3
Also, n stored in is updated, and the line means L is displayed on the display unit 4.
The letter "n" is displayed. For example, when the line selection switch SW1 is operated once while the line L1 (n = 1) is selected, the line L2 (n = 2) one level higher than the line L1 (n = 1) is selected and the "line selection L2" is displayed on the display means 4. Is displayed and the district light (not shown) of the corresponding line is blinked. (S5 to S9) When the test switch SW2 is operated, the control means 2 activates the fire test circuit 5 of the line Ln that was in the operation standby state, short-circuits the line Ln, and artificially detects the line Ln in a fire detection state. To If there is no abnormality in the circuits connected to the line Ln, the fire detection circuit 6 detects a contact short circuit of the line Ln and turns on a district lamp (not shown) corresponding to the line Ln, and the line Ln Activate alarm equipment such as the corresponding district bell (not shown). (S10 to S11) When the recovery switch SW3 is operated, the control means 2 further increases n by one higher number (n = n +).
It is automatically updated to 1), and the control means 2 puts the fire test circuit 5 of the line Ln, which is one higher level, into the operation standby state accordingly. The n stored in the storage means 3 is also updated, and the display means 4 displays the characters "line selection Ln". That is, for example, when the fire test of the line L9 is performed, the line L10, which is one level higher than the line L10, is automatically selected after operating the recovery switch SW3. (S12) When the number n becomes equal to the total number x of lines, the control means 2 sets n = 0 so that no line is selected and the line can be selected again. If n does not reach the total number x of lines, the currently selected line Ln is held and another line can be selected by the line selection switch SW1.

When the fire test is completed, the line selection switch SW1 is operated to return to the "state in which no line is selected".

Further, a timer circuit (not shown) is built in the control means 2, and when the line selection switch SW1 is in the non-operated state, the time counting is started and the time is delayed after a predetermined time (for example, 3 minutes). It is a circuit like this. The control means 2
Is a line selector switch SW1, a test switch SW2, a recovery switch SW3 of the fire receiver 1, and other switches (not shown) such as a sound stop switch, a battery test switch, and a fire hydrant interlock switch. The operation signals from all the switches provided are monitored, and if the operation signal from any switch is not detected by the time limit of the timer circuit, the line selection status is automatically changed. To release. That is, the state shifts to "state in which no line is selected".

In the present invention, the process of S10 in FIG. 1 may be omitted. In this case, the recovery switch SW
Even after the operation of 3, the line Ln for which the fire test is currently performed is retained as it is. Normally, the line to be selected next has a number close to it, so the next line can be selected from the held lines, so that the next line can be selected without operating the line selection switch SW1 many times. Can be selected. That is, for example, when the fire test of the line L10 is performed, after operating the recovery switch SW3, the selected state of the line L10 is maintained as it is, and then, for example, the line 1
When selecting 2, the line selection switch SW2 may be operated only twice. (In the case of the above conventional example, the line selection switch must be operated 12 times at this time.) In this embodiment, the 7-segment portion 4 of the display means 4
Each time the line selection switch SW1 is operated, the number n incremented by 1 is displayed in a.
The upper one line (for example, the line one higher than the line 3 is the line 4) is selected, but in the present invention, for example, one line below the one line (for example, the line selection switch SW1 is operated). The line one lower than line 3 is line 2)
May be selected.

Next, a second embodiment according to the present invention will be described.
FIG. 5 shows the line selection switch SW1 in the second embodiment.
FIG. 8 is a front view (a) and a side view (b) showing (hereinafter, also referred to as a rotary encoder SW1), and FIG. 8 is a waveform diagram showing an output signal of the rotary encoder SW1. In the second embodiment, the line selection switch SW1 of the first embodiment is constructed by a rotary encoder as shown in FIG. 5, and the other constructions are the same as those of the first embodiment. Omit it.

The rotary encoder SW1 has a manual rotating shaft SWa, a signal terminal A, a signal terminal B, and a common terminal C. Each time the rotating shaft SWa is rotated rightward by one step. As shown in FIG. 8, operation signals having different phases (output timings) and pulse widths are output from the signal terminals A and B, respectively. The control means 2 is adapted to detect only the operation signal with the earlier output timing among the signal terminals A and B, and when the rotation shaft SWa is rotated rightward by one step. Since the output signal from the signal terminal A has a faster output timing than the output signal from the signal terminal B, only the operation signal from the signal terminal A (hereinafter, referred to as “first operation signal”) is detected. Also, the rotation axis SWa
Is rotated one step to the left, the output pulse from the signal terminal B has an earlier output timing than the output pulse from the signal terminal A. Therefore, the operation signal from the signal terminal B (hereinafter, referred to as “second Only the "operation signal") is detected.

FIG. 6 is a diagram showing a part of the functional blocks of the fire receiver in the case where the line selection switch SW1 is composed of a rotary encoder, and FIG. 7 is the display when the rotary encoder SW1 is rotated. Means 4
It is a figure which shows the display content.

The line selection switch S as in the second embodiment.
When W1 is composed of a rotary encoder, the functional block of FIG. 6 is added to the functional block diagram of FIG. 1 showing the first embodiment. The control means 2, the display means 4, and the storage means 3 shown in the first embodiment are the same as those shown in FIG.

In FIG. 6, reference numeral 8 is a non-volatile memory (ROM) for programs. The program is also stored in a partial area of the volatile storage unit 3.

Numeral 9 is a timer circuit similar to that of the first embodiment, which starts counting when the line selection switch SW1 is in a non-operated state and starts a predetermined time (for example, 3 minutes).
It is stored in the non-volatile memory 8. ) It is a circuit that will be timed later. The control means 2 automatically cancels the line selection state when the operation signal from any of the switches is not detected by the time limit of the timer circuit 9.
That is, the state shifts to "state in which no line is selected". still,
The timer circuit 9 may be installed externally or may be a clock generated by the central processing unit (CPU) which is the control means 2.

The operation of the second embodiment will be described. First,
Assuming that the rotary shaft SWa of the rotary encoder SW1 is rotated rightward by one step, the control means 2
Of the two signals output from the rotary encoder SW1, only the first operation signal with an early output timing is detected, and the line Ln one higher than that is selected accordingly, and the fire test circuit 5 connected to the line Ln is selected. Put in operation standby. As shown in FIG. 7, for example, when the line is not selected (S20), the rotary shaft SWa is moved rightward by one.
When the step rotation is performed, the line L1 is selected as in S21, and when the rotation axis SWa is further rotated rightward by one step, the line L2 is selected as in S22, ... (Omitted) ... When the rotary shaft SWa is rotated rightward by one step, the line Ln is selected as Sn, and when the rotary shaft SWa is further rotated rightward by one step, the line is returned to the non-selected state as S20. It is in good condition.

Next, assuming that the rotary shaft SWa of the rotary encoder SW1 is rotated one step to the left,
Of the two signals output from the rotary encoder SW1, the control means 2 detects only the second operation signal with the earlier output timing, and accordingly, the control means 2 selects the one lower line Ln, The fire test circuit 5 connected to Ln is put into an operation standby state. As shown in FIG.
For example, in the state where no line is selected (S20),
When the rotating shaft SWa is rotated leftward by one step, S
When the line Ln is selected like n, and the turning axis SWa is further turned leftward by one step, the line L7 is turned like S27.
Is selected (... omitted in the middle), and the rotation axis S
When Wa is rotated leftward by one step, the line L1 is selected as in S21, and when the rotation axis SWa is further rotated rightward by one step, the line is not selected as in S20. .

In the above-described structure, for example, it may be rotated to the right by several steps to rotate from the middle to the left, or conversely, may be rotated to the left from several steps to rotate to the right from the middle. It is possible to freely select the upper or lower line.

In the second embodiment, if the rotary encoder SW1 is rotated rightward by one step, the upper lines are selected one by one, and if it is rotated leftward by one step, the lower lines are selected one by one. The line is selected. For example, when the line 10 is selected, the rotary encoder rotates exactly once. For example, when the line selection switch is composed of a rotary switch, the line cannot be rotated more than once. Therefore, it is not possible to select lines 11 or more, but by configuring with the rotary encoder SW1 as in this embodiment, in order to select lines 11 or more, for example, line 15, an extra 5 steps in the same direction is required. You can select it by rotating it. That is, in this embodiment, if the number of lines increases, the rotary encoder SW
By rotating 1 in the same direction more than once, it is possible to select the upper or lower line, so even if the system is expanded by adding more lines later, one rotary encoder SW1 can be used. There is no need to provide a switch for line selection in. The number of rotations of the rotary shaft SWa of the rotary encoder SW1 may be several, taking into consideration the maximum number of lines that can be added, or may be one or both without limitation.

Contrary to the above, when it is detected that the rotary shaft SWa has been rotated one step to the right, the control means 2 selects one lower line Ln accordingly, and the rotary shaft SWa is rotated. When it is detected that the SWa is rotated one step to the left, the control means 2 may select the line Ln one higher than the switch Ln.

When the fire test is completed, the line selection switch SW1 is operated to return to the "state in which no line is selected".

The operation of the second embodiment is substantially the same as that of the first embodiment shown in FIG. 1. For example, after the recovery switch SW1 is operated to recover, the next upper line is automatically operated as in the process of S10. Is selected, the process of S10 may be omitted in this case as well. In this case, the line Ln currently subjected to the fire test is retained as it is, even after the recovery switch SW3 is operated. That is, for example, when a fire test of the line L3 is performed, the selected state of the line L3 is maintained as it is after operating the recovery switch SW3.

The specifications of the rotary encoder SW1 are not limited to those of the two-signal type as described above, but may be of any type as long as the specifications allow distinguishing the rotating direction of the rotating shaft SWa. .

Further, the rotary encoder SW1 may be rotated only rightward or leftward.

Each time the control means 2 detects an operation signal generated by the rotary encoder SW1, n is updated by one to the upper (n = n + 1) or lower (n = n-1), and the storage means 3 is updated. The "n" stored in is updated and is displayed on the display means 4 as "line selection Ln".

In the second embodiment, S20 of FIG.
There is no need to perform the process of step S21, that is, the process of changing to the "state not selected", so that the process of S21 (selecting line L1) is directly transferred to the process of Sn (selecting line Ln) and the process of Sn. It is also possible to directly shift from (select line Ln) to the process of S21 (select line L1).

Also in the case of the first embodiment described above, similarly, the processing of "state in which no line is selected" may be omitted.

In the first and second embodiments, a clock is provided and a unique time (for example, 13:30) is set.
It is also possible to automatically shift to the state where the line is not connected.

[0048]

According to the present invention of claim 1 configured as described above, since the number of times of operation of the line selection switch is small before reaching the line of the next object on the basis of the line, it is possible to perform the fire test. Easy and quick line selection.
Further, since the line selection switch can be configured by one switch, the space for disposing the switch can be reduced.
