Abstract

PURPOSE:To reduce cost and to quickly inform the external part of the alarm output by performing the disaster prevention and crime prevention monitoring with a television receiver for home. CONSTITUTION:A sensing signal from a sensor 1a for disaster prevention and a sensor 1b for crime prevention is converted to a pulse code by receiving parts 2a and 2b of an adapter panel 10 and synthesized to a pulse code colum at a signal synthesizing part 3. A signal processing part 4 performs the checking of the number of bits, and when an abnormal code is decided, a signal is transmitted to an image synthesizing part 7. The image information inputted beforehand from a data input part 6 is once stored into an image storing part 5, and when the abnormal code occurs, the signal processing part 4 reads and outputted to the image synthesizing part 7, and displayed at a television receiver 12 by the flickering, etc., of the displaying of the alarm generating source of a screen. An alarm signal is outputted through the image synthesizing part 7, and an alarm output part 8 to an external terminal 9.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster prevention/crime prevention monitoring system, and more particularly to a disaster prevention/crime prevention monitoring system for ordinary households.

0002

2. Description of the Related Art Conventional home disaster prevention devices have mainly been used to notify alarms by sounding alarm buzzers using sensing signals from various sensors. Additionally, as a security device, monitoring was carried out by displaying images from a video camera on a dedicated receiver.

0003

The above-mentioned conventional home disaster prevention devices mainly use buzzer alarms using various sensors, and security devices mainly use a video camera and a dedicated receiver. Therefore, if you use both,
The drawback is that it is difficult to spread to general households because of its high cost.

[Means for Solving the Problems] The disaster prevention/crime prevention monitoring system of the present invention uses disaster prevention/crime prevention sensors installed at key points in the home and signals sensed by any of these disaster prevention/crime prevention sensors. The present invention is characterized by comprising an alarm means for displaying an image of the location and cause of the source on a home television receiver.

[0005] The alarm means includes a signal synthesizing section that synthesizes sensing signals from the disaster prevention/crime prevention sensor into a pulse code train, and image information of the placement location of the disaster prevention/crime prevention sensor in the home in advance. an image storage unit that reads the image information from the image storage unit according to the pulse code from the signal synthesis unit and outputs the image information to the image synthesis unit; and the image synthesizing section that displays on the home television receiver and drives an alarm output section, and further, when the alarm output section is driven, turns on the power of the home television receiver, A power control means may be provided that detects the off state and automatically turns on the off state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the disaster prevention/crime prevention monitoring system of the present invention, and FIG. 2 is a diagram showing an example of the screen display of the television receiver in FIG. 1.

In FIG. 1, sensing signals from disaster prevention sensors 1a such as gas detectors and smoke detectors and crime prevention sensors 1b such as door and window open detectors are converted into pulse codes by receiving sections 2a and 2b of an adapter panel 10. The signal synthesizer 3 synthesizes this into a pulse code string. Signal processing section 4
checks the number of bits, and when an abnormal code is determined, transmits a signal to the image synthesis section 7. Further, the image information input in advance from the data input section 6 is temporarily stored in the image storage section 5, and when an abnormal code occurs, the signal processing section 4 reads it out and outputs it to the image composition section 7, as shown in FIG.
This is displayed on the television receiver 12 by blinking the alarm source display on the screen shown in FIG. Further, the alarm signal is transmitted to the alarm output section 8 via the image composition section 7, and is transmitted to the external terminal 9.
A notification is made by sounding a buzzer, emergency bell, etc. Further, at the same time as this notification, the alarm output section 8 checks whether the power of the television receiver 12 is turned on or off, and if it is off, the power control section (not shown) automatically turns it on.
have. Therefore, even if the viewer is sleeping, after hearing the alarm sound, the viewer can know the location and cause of the alarm source on the television screen.

[0008]

Effects of the Invention As explained above, the present invention utilizes a commercially available home television receiver to carry out disaster prevention and crime prevention monitoring, which not only reduces costs but also provides alarm output. This also has the effect of making it possible to promptly notify the outside world.
