Description

[Detailed description of the invention] (a) Industrial application field This invention notifies abnormalities detected by an intrusion sensor attached to a window or other abnormality detecting sensor with sound (including voice). The present invention relates to an alarm system, and particularly to an alarm system characterized by using sound for signal transmission.

(B) Conventional technology Conventionally, as shown in Figs. 7 and 8, an alarm system consists of a handset port connected to and provided near a detection means (sensor) for detecting an abnormality, and a handset (transmission 1! which is installed away from the lN27) and notifies abnormalities by sound, etc. It is possible to connect the sensor (e) and the main unit (to) electrically using radio waves (Fig. 7), or directly connect the sensor (e) and the main unit (to) using an electric wire (signal line). A well-known example is the one that connects to the (Fig. 8).

In devices that use radio waves (hereinafter referred to as radio wave method), abnormalities detected by the sensor are transmitted from the slave unit to the base unit by radio waves.
There is something that transmits a signal to □. Upon receiving the signal, the base unit issues, for example, an alarm sound to notify the user that an abnormality has occurred.

In those that use electric wires (hereinafter referred to as the electric wire method), signals from the sensor (g) are transmitted through the electric wires.

(c) Problems to be solved by the invention However, in the radio wave system, +a) Since radio waves are used, if there is a stronger radio wave in the same frequency band, the signal radio wave is masked,
There is a possibility that the signal will not be transmitted. +b+ Also, if you are using a large number of slave units, there is a possibility that the signal will not be transmitted if the signals sent from multiple slave units are sent at the same time. (C) Radio waves do not pass through metal, so it is necessary to carefully check reception at the time of installation, and if radio waves cannot be received, it is necessary to add an extension antenna, amplifier, etc. <cb In addition, since the radio waves themselves cannot be seen, checking to see if the radio waves are reaching requires a special measuring device and a certain level of skill, which is not something that anyone can do easily. (e) (Related to Section C1) However, since radio waves do not pass through metal objects, even if it is usable at the time of installation, if a metal locker or large refrigerator is installed between the slave unit and the base unit after installation, it will not work. , there was a problem that there was a possibility that signals that could be received up to now could no longer be received.

In addition, in the electric wire method, all +I'+ wire (c) wiring is concentrated at the main unit (to), so if installed in an existing building, the wiring will be exposed and will be very unsightly, so it is practically impossible to install it in a new building. It cannot be installed in 1(]) If! ! It was necessary to wire all the cables from the sensor (c) to the sensor (c), and the wiring and connections required specialized knowledge, and the construction period was relatively long and the construction cost was high.

This invention was made in view of the above circumstances, and uses sound or synthesized voice to transmit signals, allowing anyone to easily install and confirm the installation, and also allows the user to easily understand the alarm sound itself. fF1 uses synthesized speech that can be understood by
151.

(d) Means for Solving Problems The present invention has a configuration that includes a detection means for detecting an abnormality, a signal sound generation means for outputting a signal sound to notify the abnormality, and a sound collection means for collecting external sounds. , name recognition means for determining whether or not the collected sound is the same as a preset signal sound; and an output signal from the detection means to actuate the signal sound generation means and from the sound recognition means. ll, 111 for activating the signal tone generating means by the output signal of
A subordinate consisting of 11 means? an alarm device, a signal sound generation means for outputting a plurality of types of signal sounds, a sound collection means for collecting the signal sounds from the slave alarm device, and a signal sound that is collected is the same as a preset signal sound. a sound recognition means for determining whether or not the alarm is present; a switch means for selecting the operating state of the sub-alarm device; and controlling the operation of the signal sound generating means by a signal from the switch means and an output signal from the sound recognition means. , II 11 means.

(e) When the action detection means detects an abnormality, the control means of the slave alarm device activates the signal sound generation means to output a signal sound made of synthesized audio. The main alarm device collects the signal sound emitted from the slave alarm device using the sound collection means, and uses the sound W1 recognition means to determine whether it is the same as the signal sound predetermined by i, and if it is the same, The control means operates the signal sound generating means to output the same signal sound as the signal sound output by the slave alarm device, so that the user can easily confirm the abnormality.

(F) EXAMPLES Hereinafter, examples of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to the following examples.

In Fig. 1, (1) is the detection means (sensor), and as in the past, the signal line (2) is the slave alarm device (W hat m).
Connected to +31. The detection means (1) is an intrusion sensor, a smoke sensor, a humidity sensor, etc. that is installed in a window or the like to detect intrusion from the outside. (4) is the main alarm device (alarm f
Fi base unit), the sound stop key (5) is the switch means.
, and a ¥I precept/cancellation switch key (6) are provided on its surface. This υ alarm system (in the sword, the detection means (
1) and the secondary alarm device (3) are installed relatively close to each other, and the main alarm device (4) receives the signal from the secondary alarm device (3). i
(It is installed in the range that 81 can reach.

What is shown in FIG. 2 is a block diagram of the main alarm device (4).

(9) is a sound collection means that converts the signal sound (8) output from the slave alarm device (3) into an electrical signal using a dynamic microphone, etc., and then converts it into a digital signal etc. and sends it to the sound recognition means (101). Output. Sound recognition means (
101 contains an RO in which the same sound as Shin@sound (8) is stored.
M (read-only memory)' (10a) is built-in. (11) is a control means which controls the main alarm device (
4), and is preferably a microcomputer, for example. [F] is a signal sound generating means,
a speech synthesis circuit 03) connected to the control means (11);
It consists of a filter amplifier (14) that amplifies the synthesized voice signal and alarm signal of the voice synthesis circuit OJ, and a speaker (151) connected to the filter amplifier.

What is shown in FIG. 3 is a block diagram of the slave alarm device (3).

(16) is a sound collecting means, for example, when a plurality of slave alarm devices are used, a signal sound (8) output from another slave alarm device (not shown) is converted into an electrical signal using a dynamic microphone or the like. After that, it is further converted into a digital signal and outputted to the sound recognition means 07). The sound recognition means +17) has a built-in ROM CFA memory (17a) in which the same sound as the signal sound (8) is stored. (Incorporated) is a control means which operates the signal sound generation means by the output signal of the detection means (1) or the output signal of the sound recognition means (17). The signal sound generating means includes a voice synthesis circuit connected to the control means (incorporated), a filter amplifier (21), etc. that amplifies the synthesized voice signal of the voice synthesis circuit ■ and the alarm signal.
1) and a speaker G connected to the speaker G.

Next, the operation of this embodiment will be explained with reference to FIGS. 4 to 6.

Normally, the main alarm system (
It is necessary to switch the mode (state) of 4) using the alarm/cancellation switch key (6) to a mode in which the alarm does not sound even if the window is opened, or a mode in which the alarm does sound. Of course, even if the alarm/cancellation switch key (6) is switched, the intrusion mode is simply switched, and fire monitoring remains constant.

Step 1oo) When the alarm/cancellation switch key (6) of the main alarm device (4) is switched to alarm, the control means (1
1J synthesizes a warning sound (C) into a voice in a voice synthesis circuit (131) in order to send a signal indicating a warning state to a sub-alarm device (3), and the synthesized voice signal is sent to a filter amplifier (
After being amplified by I4), a warning sound (
(to) is output (step 101). Of course, this warning sound can also be used as a confirmation sound for the operator, and as shown in Figure 6, it uses a sound with a higher frequency (B) than the audio frequency band (A). It may be a sound with a lower frequency than the band (A>).

The secondary alarm device (3) collects the above-mentioned alarm sound as a sound signal using the sound collecting means (step 200), and compares the sound recognition means with the data in the built-in ROM (17a) to determine that the alarm sound is a sound signal (step 200). If it is determined, the control means (goods) sets the alarm mode (step 201).

When the main alarm device (4) is set to release mode using the warning/wI cancellation key (6) (step 102), a release sound is output in the same way as in the warning mode.Step 103), the secondary alarm device (3) (may be more than one) are set to release mode (step 202). When the slave alarm device (3) in the alarm mode receives an intrusion abnormality signal (for example, heard at the window) from the detection means (1) to the control means (18) (step 203), g Intrusion abnormal synthesized voice (
For example, a thief...thief...) is made, and after being amplified by a filter amplifier (21), it is output as sound from a speaker (step 204).

The intrusion abnormality synthesized voice output from the secondary alarm device (3) is
When the sound is received by the sound collection means (9) of the main alarm device (4) (or other sub-V alarm devices if there are multiple sub-alarm devices), the built-in ROM (10a) is detected by the sound recognition means (g)).
In step 104), the signal is output as an intrusion abnormality signal from the control means (11) to the speech synthesis circuit 03), and after being amplified by the filter amplifier (14), it is output again from the speaker 05) (step 105).

Similarly, when the detection means (1) detects a fire (step 205), the slave alarm device (3) makes a signal sound to notify the occurrence of a fire, regardless of the mode of the alarm/cancellation switch key (6). For example, "There is a fire" is output repeatedly and continuously (step 206). Then, the main alarm device (4) collects this signal sound and recognizes that it is a signal sound (step 10G). - Similar to the S alarm device (3), it outputs a synthesized voice signal &"It's a fire" (step 107) to notify the user that a fire has occurred.

If the user wants to take measures to deal with the abnormal condition and stop the signal sound while notifying the above abnormality, the main alarm device (4)
When the sound stop key (5) is pressed (step 108), the stop sound 34) shown in FIG. 6 is output (step 100).
), the sound is collected by the sound collecting means 06), and the sound is collected by the wide sound recognition means (1).
At step 7), the voice is recognized, and the control means 08) stops the signal sound notifying the abnormality. In other words, the output of all signal sounds from the main alarm device (4) and the slave alarm device (3) that have been sounding until now is stopped.

In addition, when a plurality of slave alarm devices and detection means are installed, when one pair of them reports an abnormality, the remaining slave alarm device acts as a relay station, that is, it recognizes the signal sound and collects the sound. By outputting the same signal sound, the occurrence of an abnormality can be transmitted to a main alarm device installed at a long distance.

(g) Effects of the invention - According to the present invention, an alarm system can be obtained that exhibits the extremely beneficial effects described below.

In other words, (I) Synthesized voices are used to transmit signals to notify abnormalities, so people within the range can easily understand the meaning of the abnormal state, even children. (IF) Multiple When using a secondary alarm device, the relay is performed using voice synthesis, so it is easy to determine whether the signal sound will reach you even during installation, and anyone can carry out the construction work reliably. Since there is no need for wired wiring in between, the construction is easy and the installation time is short. It is easy to add secondary alarm devices, and since the secondary alarm devices are scattered, it has a particularly strong threatening effect against intruders. This has the advantage that it can be made at a much lower cost than devices that recognize speech from unspecified speakers.
