Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to an abnormality display device for a home security system.

<Prior art> Recently, devices have been installed in each house to monitor disaster prevention and crime prevention within the house and issue emergency warnings in the event of an abnormality.
Comprehensive home security systems are being developed that can immediately detect and issue an alarm when an abnormality occurs. Conventionally, in such a system, after dealing with an abnormality and removing its cause, when an operation is performed to stop the alarm lamp or alarm sound, the lamp is immediately extinguished and the alarm is stopped. However, with this method, only the person who dealt with the abnormality will know about the abnormality occurrence, and other people may remain unaware of the abnormality occurrence, and there may be cases where there is a high possibility that the abnormality will occur again or if no measures are taken. In some cases, insufficient communication could lead to serious disasters.

<Purpose of the Invention> The present invention solves the above-mentioned problems of the prior art, and in the case of an abnormality that causes a serious disaster, it is possible to notify people other than the person responding to the abnormality even after the abnormality has been resolved. The purpose is to prevent disasters from occurring again.

<Structure of the Invention> The abnormality display device of the in-house security system of the present invention includes a detection means for detecting multiple types of abnormalities that occur inside a home, such as fire, intrusion, and gas leaks, and a detection means for detecting a plurality of types of abnormalities that occur inside a home, such as fire, intrusion, and gas leak. A transmitting means transmits a code signal according to the type, and an abnormality display is performed based on the transmitted signal, and if the detected abnormality is a specific type of abnormality set in advance, the abnormality display is reset continuously from the abnormality display reset operation. The apparatus is characterized by comprising an abnormality display means that continues a display state for a certain period of time.

<Example> FIG. 1 is a block diagram showing an example of the present invention.
Figure 2 is a front view of the operation panel of the central controller;
The figure is a time chart showing the operation of the embodiment.

For example, a fire transmitter E that outputs a signal indicating a fire, an intrusion transmitter F that outputs a signal indicating an intrusion, a gas leak transmitter G that outputs a signal indicating a gas leak, and a water level in the bath at various places in the house. Alternatively, a bath transmitter H that transmits an abnormality in water temperature, a water leak transmitter I that detects a water leak, and transmits a signal, etc. are installed. Each transmitter E, F, G, H, I has a sensor,
When an abnormality is detected, a weak radio wave is sent to the central controller A along with the code assigned to each transmitter. Central controller A has CPU and ROM,
A microprocessor consisting of RAM memory, an interface for input/output equipment, a receiver that amplifies and detects the radio waves received by the antenna J, and inputs the signals, an abnormality indicator lamp K that displays the abnormal state and type of abnormality, and a family member. Alarm device L that emits an alarm sound such as a buzzer,
It is equipped with a stop switch M that turns off the abnormality indicator lamp K and stops the alarm sound, and receives radio waves from the transmitter with an antenna J, converts them to logic level in the receiver, and then decodes the signal with a microprocessor. , the display lamp K corresponding to the signal is turned on, and an alarm is sounded. In addition, the central controller A outputs a signal to the power line, and the sub-controller B receives the signal and sounds the same type of alarm sound as the central controller A. Further, if necessary, the central controller A drives an outdoor bell C or a doorbell D to sound an alarm outdoors to notify neighbors and passersby of the occurrence of an abnormality. When the abnormality transmission lamp K is turned off and the alarm sound is to be stopped after the troubleshooting has been completed, pressing the stop switch M once will stop the alarm sound, and pressing the stop switch M a second time will cause the abnormality display lamp K to stop. is turned off. In this case, when the abnormality indicator lamp K is turned off by the second push operation of the switch M, the indicator lamps K ₁ and K ₂ corresponding to each abnormality are turned off.
…Among _K5 , the indicator lamp _K1 corresponding to a specific type of abnormality selected in advance, such as fire, continues to be displayed for a certain period of time even after the light is turned off, and then turns off automatically, and other abnormality indicators This is different from the case where lamps K ₂ , K _{3 ,} etc. are turned off at the same time when the lights are turned off. As a means to continue displaying for a certain period of time even after turning off the indicator lamp _K1 , for example, a switching circuit with a timer is installed in the circuit from the power supply to the indicator lamp _K1 , and the timer is activated by the signal from the switch M to keep the display constant. It can be configured to switch off after a period of time. The retention period of the lighting state can be set appropriately, such as one day or several days.

To further explain using the time chart in Figure 3,
When an abnormality occurs at time _T1 , an alarm sounds and an abnormality indicator lamp lights up. The troubleshooting for the abnormality is completed at time _T2 , and when the stop switch M is pressed at time _T3 , the alarm sound stops. When the switch M is operated for the second time at time T ₄ , if the above-mentioned abnormality is of a type that has not been selected in advance, such as a water leakage abnormality, the abnormality display lamp K ₃ will immediately turn off at time T ₄ . . On the other hand, if the anomaly is a pre-selected anomaly,
For example, in the case of a fire, the abnormality indicator lamp K ₁
does not turn off at time _T4 , but turns off only after a certain period of time has elapsed at time _T5 .

<Effects> The present invention has the above-described configuration, and in response to an abnormality caused by a preselected serious disaster, the abnormality indicator lamp maintains the display state for a certain period of time even after the operation to turn off the lamp, so that the abnormality can be prevented even when the abnormality occurs. It is possible to continue to display the information even after the abnormality has been dealt with, so that even those who were unaware of the abnormality can be informed, and those who have dealt with the abnormality can continue to be careful, so that the abnormal situation can be continuously displayed. It is highly effective in preventing recurrence.
