And both can be selected appropriately according to the installation location. Note that the alarm device 1 can be easily attached to an installation location by an attachment (not shown) such as a magnet rubber or a belt.

The sensor 4 can be, for example, an infrared sensor such as a pyroelectric sensor, and is mounted so that the detection unit is exposed on the front side of the case 2. This sensor 4
Outputs a sensor signal when detecting the approach of a person. The sensor signal is amplified by the sensor signal amplification output circuit 20, and then output to the changeover switch 8. Note that the amplification degree of the sensor signal can be adjusted by the sensitivity adjustment volume 22.

The timer 6 outputs a timer signal at predetermined time intervals.
Output to.

The changeover switch 8 has an operation section provided on the front side of the case 2 and functions as signal selection means for selecting either a sensor signal from the sensor 4 or a timer signal from the timer 6. I do. This changeover switch 8
, It is determined whether the sensor 4 or the timer 6 is activated when the power switch 32 is turned on, and the generated sensor signal or timer signal is transmitted to the alarm sound generating means 10 as an activation signal. .

The alarm sound generation means 10 includes a sound recording / reproducing IC 12 having a memory unit and a control unit (not shown), and a case 2 as a sound signal inputting unit to the sound recording / reproducing IC 12.
Recording terminal 14 provided on the side of

The recording level of the audio signal input from the recording terminal 14 and the reproduction level of the audio message output from the speaker can be adjusted by the input volume 24 and the output volume 26, respectively.

When the operation signal from the changeover switch 8 is input, the control section of the voice recording / reproducing IC 12 outputs a voice output signal based on the voice data recorded in the memory section to the voice output sections 16 and 18. I do.

The alarm light generating means (not shown) is
And a plurality of orange or yellow LEDs 44 provided around a display plate 42 attached to the front of the LED 44, and an LED switching blinking circuit (not shown) connected to the LEDs 44. The LED switching blinking circuit is configured such that when the power switch 32 is turned on, the LED 44 always blinks and emits light. The display plate 42 is provided with a display that alerts a pedestrian to visual attention, such as "under inspection" or "under work", and is provided detachably with screws or the like.

Next, the operation of the alarm device 1 will be described. First, the switch 8 is operated to select whether the voice message is output by the sensor 4 or the timer 6. In general, the sensor 4 should be selected when there are few traffics at the installation location, and the timer 6 should be selected when the traffics are heavy. When the sensor 4 is selected, it is desirable to adjust the sensitivity adjustment volume 22 so that a sensor signal is input to the voice recording / reproducing IC 12 when a person approaches to about 5 m.

Then, it is attached to an appropriate installation place at the work site via a fixture (not shown). For example, in the case of an elevator inspection, as shown in FIG. 3A, the alarm device 1 can be attached to a metal part around the door that is easily visible via a magnet rubber. As shown in FIG. 3B, it can be attached via a belt to a cone placed in the passage.

After the installation preparation is completed, the power switch 32 is turned on, and the alarm device 1 is operated. When the sensor 4 is selected by the changeover switch 8,
When a person approaches a predetermined distance, the voice recording / reproducing IC 12
Is supplied with a sensor signal. Thereby, based on the voice data recorded in the memory, for example, a voice message such as “We are currently carrying out an inspection of the elevator facilities.” Flows from the speaker 18, and the pedestrian hears the voice message. You can call attention. Also,
Since the LED 44 constantly blinks and emits light, it is possible to visually alert a passerby.

On the other hand, when the timer 6 is selected by the changeover switch 8, the timer signal is periodically input to the voice recording / reproducing IC 12, so that the output of the voice message is periodically performed regardless of the approach of a person. Done in As a result,
Even when traffic is intense, it is possible to avoid a situation in which sound is continuously output, so that sufficient attention can be urged through hearing without giving discomfort to passers-by. Further, also in this case, the LED 44 constantly flashes and emits light, so that it is possible to prompt a pedestrian to pay attention visually.

When the content of the voice message is changed at the site where the alarm device 1 is installed, a magnetic tape or M
The audio output line of the reproducing device of the recording medium such as D or the audio output line of the microphone is connected to the recording terminal 14 and the audio signal is input to the audio recording / reproducing IC 12 so that the audio data recorded in the memory unit is Can be changed as desired. As a result, it is possible to output a more accurate voice message corresponding to the situation of the site in a flexible manner, and it is troublesome to arrange them when there are a large number of replacement memory units as in the conventional case. The problem is solved. When it is intended to change the voice message of each alarm device 1 used at a plurality of work sites to the same content, one recording medium in which desired voice data is recorded in advance is prepared. Just put
Using this recording medium, the voice message of the alarm device at each work site can be easily changed.

As described above, one embodiment of the present invention has been described in detail, but the present invention is not necessarily limited to the above embodiment. For example, the number of messages recorded in the memory unit of the voice recording / reproducing IC 12 is not limited to one, and a memory block is divided into a plurality of pieces, and voice data having different contents are recorded in each of them. It is possible to configure so as to be able to select and output.

In addition to the rewritable memory described above, a memory such as a mask ROM in which audio data is recorded in advance and whose contents cannot be changed may be provided in the memory unit. May be configured so that a desired message can be selected from among the standard messages pre-recorded in the ROM.

This alarm device 1 can be used at work sites such as inspection of elevators and escalators, ceiling work, toilet cleaning, etc., at locations where rain leaks, and the like, and has various uses.
