Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an alarm sound generating device suitable for use as a housing information word for centrally processing and announcing various types of information in a residence.

(b) Conventional technology A housing information panel using this building alarm sound generating device provides various information inside the house, such as detecting gas leaks and fire outbreaks using gas sensors and smoke sensors, as well as detecting visitors using visitor sensors. It uses a temperature sensor and humidity sensor to notify you of the temperature and humidity, and to alert you to hemorrhoids in case of an emergency.

Figure 1 is a circuit diagram of a conventional example, where (1) is a gas sensor (2).

(5) is a sensor section consisting of a microcomputer that receives sensor signals from this sensor section (Skara) and outputs corresponding output signals; (6) is an itch control section that outputs corresponding output signals; A voice synthesis section that synthesizes appropriate words in response to give an alarm; +71 is an amplification section; (8) is composed of first to fourth resistors (9), (10), (11), and (12) and a switch (13). The volume controller (14) is a speaker for generating an alarm sound in appropriate words.For example, if the gas sensor (2) detects a gas leak, the gas sensor (2) outputs a gas sensor signal. , is input to the itching section 151. Since the itching section (5) always monitors the presence or absence of the sensor signal from the sensor section (1), it immediately detects that the human signal is from the gas sensor (2). is detected, and outputs a gas warning signal to the voice synthesis section (6).The voice synthesis section (6) includes a memory circuit for storing office voice data corresponding to each of the sensor signals. and a synthesizing circuit for synthesizing them, and generates a kidney notification audio signal such as "pee pow, peep, gas is out" according to the gas detection signal.Then, the route sound signal is The amplitude is amplified by the amplifying section (7), and by the user switching the switch (13) of the volume controller (8), the resistance-divided amplitude or the second and fourth resistors (9) and (11) are amplified. The signal is switched to three levels: resistance-divided amplitude using resistors (10) and (12), or the amplitude as it is, and then sent to the speaker (14), so that the user can hear the signal at a volume that is easy to hear.

However, according to this conventional example, both normal state notifications such as visitor notifications and emergency state notifications such as gas leaks or fires are made at the same volume, so there is a drawback that emergency state alarms cannot be adequately issued. There is.

(C) Purpose of the Invention The present invention provides notifications for normal conditions such as visitor notifications at an appropriate volume set by the user, while notifications for emergency conditions such as gas leaks and fires are made using appropriate sounds related to (1). (This is done at maximum volume to give a sufficient warning of an emergency situation.)

(d) Description of the invention The alarm generating device of the present invention generates alarm sounds corresponding to each sensor signal from a plurality of sensors such as a gas sensor, a smoke sensor, and a visitor sensor. It is characterized in that it not only makes a sound at an appropriate volume using a regulator, but also has a means for short-circuiting the volume regulator when a specific sensor signal is input manually, so that the alarm is made at maximum volume when the specific sensor signal is input manually. When a specific sensor signal is input, the notification is made at maximum volume regardless of the adjustment of the volume controller.

(e) Embodiment FIG. 2 is a circuit diagram of an embodiment of the present invention, and parts that are the same as those in the conventional example are given the same numbers and their explanations are omitted.

(15) is a calculation unit consisting of a microcomputer, and in addition to the output terminal fAl for the output signal to the voice synthesis unit (6), the sensor signal is output from a sensor in an emergency state such as a waste sensor signal or a smoke sensor signal. It is provided with a control output terminal (B) which outputs a high-level activation signal when the signal is received, and a low-level stop signal when the sensor signal is in a normal state such as a visitor sensor signal. (16
) is a short-circuit circuit that short-circuits the volume controller (8), and includes a control transistor (17) whose base end is connected to the control output terminal (B) via a base resistor (17), and this transistor (18). ) to the collector terminal of the relay coil (
19a) is connected to the control relay (19), and a constant relay switch (19b) of the control relay (19) is connected in parallel to both ends of the volume controller (8). There is.

Then, the sensor signal in the normal state is transmitted to the arithmetic unit (15).
), the corresponding output signal or silent a component (6)
and the control output terminal (Bl outputs stop No. 18, so the short circuit 6) is not activated, so the sound is synthesized in the voice acid section (6) and amplified in the amplification section (7). The user inputs the breaking news audio signal to the speaker (14) at an appropriate amplitude adjusted by the switch (13), and the speaker (14)
4) An appropriate sound will be used to notify you.

On the other hand, the sensor signal of the emergency state is detected by the arithmetic unit (15).
), the corresponding output signal or speech synthesizer ((5)
and the control output terminal (13) outputs an activation signal, so the short circuit (16) is activated, and the volume controller (8 parts) is connected, so the corresponding alarm audio signal reaches its maximum amplitude. to input to the speaker (14), and
4) is to issue the alarm at maximum volume to ensure that the alarm is sent far away.

Incidentally, FIG. 3 shows a flowchart of a part of the processing procedure stored in the microcomputer of the presentation section (15) in order to carry out such an operation.

(f) Effects of the Invention Therefore, according to the present invention, the notification in the normal state is made at an appropriate volume set by the user, so the notification can be opened comfortably without being noisy, while the specific sensor signal in the egg weight state is When inputting, it is performed at the maximum volume regardless of the appropriate volume set for the line used, so it can be reliably notified even far away.
It is possible to clearly communicate that there is an emergency situation.
