Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a notifying device, and more particularly to a notifying device capable of promptly notifying. 2. Description of the Related Art Notification devices for notifying emergency situations such as fire or accident by pressing a push button are widely used not only in offices and department stores in buildings but also in ordinary households. In this type of notification device, sometimes the push button is erroneously pressed. In this case, if the report is not canceled promptly, a large-scale emergency response will be started, and a great deal of human and facility loss will occur. Therefore, the conventional notification device is configured so that a notification is sent to the monitoring center only after a certain period of time has elapsed since the push button was pressed in order to release the notification due to an erroneous operation. [0003] Such a conventional notification device is configured, for example, as shown in FIG. FIG. 4 shows a timing chart of the signals of the respective units in FIG. The operation of the notification device shown in FIG. 3 will be described with reference to FIG. When the push button is pressed, the push button detection unit 1 detects the press information and outputs a press pulse signal A to the timer 2.
The timer 2 responds to the press signal, that is, a predetermined time T1 in response to the fall of the press pulse signal A.
The pulse signal B having the width is transmitted to the timer 3. Timer 3
The pulse signal D is output to the notification generation circuit 4 in response to the fall of the pulse signal B. The notification generation circuit 4 includes a timer 3
The notification signal is sent to the monitoring center via the telephone line only after receiving the output pulse signal D from. That is, the falling of the pulse signal D having the pulse time width T2 is detected, and the notification signal is transmitted from the notification generation circuit 4 to the monitoring center side. In the above configuration, even if the push button is erroneously pressed, the notification signal is actually transmitted via the telephone line after the delay time set in the timers 2 and 3 has elapsed. If the canceling operation is performed before the delay time elapses, the sending of an erroneous message to the monitoring center is prevented. [0004] As described above, in the conventional notification device, a specific delay time is given between the time when the push button is pressed and the time when the notification signal is actually transmitted, so that the notification signal due to malfunction is given. Sending was prevented. However, although such a conventional notification device can prevent the generation of a notification signal due to a malfunction of the push button, the notification signal is not transmitted until the above-described delay time elapses from the pressing of the push button, so that the notification is delayed, and the time is reduced. There is a problem that it is not possible to immediately respond to an emergency situation. SUMMARY OF THE INVENTION It is an object of the present invention to provide a reporting device that prevents the transmission of a reporting signal due to a malfunction and enables the prompt transmission of the reporting signal. [0006] In order to solve the above-mentioned problems, a notification device according to the present invention detects a notification operation from an operation unit for making a notification and outputs a first signal. Means for outputting a second signal after a predetermined first time in response to the first signal;
AND logic means having a reset function of inputting the second signal and the second signal, sending an output signal thereof to the timer means, and interrupting the generation and output of the second signal at the timing of the output signal; And notification signal generating means for outputting a notification signal in response to the second signal. According to the present invention, when a notification signal is generated after a predetermined delay time has elapsed after a predetermined operation for notification, when the predetermined operation is performed again, the delay time is reset. Since the notification is made before the elapse of the predetermined delay time, not only the notification can be canceled due to an erroneous operation, but also a notification can be promptly made when a truly emergency occurs. Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an embodiment of a notification device according to the present invention, and FIG. 2 is a signal timing chart of each part of the configuration of FIG. 1 and 2, components denoted by the same reference numerals in FIGS. 3 and 4 indicate components having the same functions. When the push button is pressed, the pressed state is detected by the push button detector 1 and the pulse signal A is output. This pulse signal A is supplied to the timer 2 and one input terminal of the AND gate 5. The timer 2 sends a pulse signal B having a pulse (time) width T1 to the other input terminals of the timer 3 and the AND gate, similarly to the operation of FIG. Timer 3
Sends a pulse signal D having a time width T2 to the notification generation circuit 4 at the fall of the output pulse B from the timer 2, and sends the notification signal to the monitoring center side via a telephone line. When the push button is first pressed, the push button detecting section 1 outputs a pulse signal A and the timer 2 outputs a pulse signal B having a time width T1. In the case where the push button is not pressed but is pressed due to an emergency, a second press is performed following the first press. That is, the pulse signal B
Is pressed for the second time within the generation time width (within the delay time T1), the pulse signal A 'is supplied to the AND gate 5, and the AND output pulse signal C of the pulse signals A' and B is supplied to the timer 2. Will be output. When receiving the pulse signal C, the timer 2 interrupts the generation of the pulse signal B at that time (the timer 2 is reset), makes the pulse fall (B '), and outputs the pulse signal D' from the timer 3. Output. As a result, the normal notification delay is canceled by the second press of the push button, and the notification signal is immediately transmitted to the emergency center side, so that prompt notification is possible. Therefore, the conventional report delay time T1 is reduced to T3. In the above description, an example in which notification is performed by operating a push button has been described. However, it is a matter of course that the present invention can use switching means other than the push button. As described above, the notification device according to the present invention has a configuration in which a notification signal is generated after a predetermined delay time has elapsed after a predetermined operation for notification.
Since the delay time is reset by the predetermined operation again, and the notification before the elapse of the certain delay time is performed, the notification due to the erroneous operation can be canceled, and the notification in the event of a truly emergency can be promptly performed.
