Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a household centralized monitoring device, and more particularly to a device for controlling the opening and closing of dangerous sources such as gas and electricity using a breaker when going out.

Conventionally, there are fire detectors, intrusion detectors,
Household centralized monitoring devices are used that are equipped with gas leak detectors and the like, and receive these signals on a monitoring panel installed at a predetermined location in the home and display an alarm.

This invention uses such a home centralized monitoring device to
It is possible to control the opening and closing of the supply of household gas such as city gas or electricity as necessary, and also prevents leakage of raw gas due to unforeseen circumstances such as power outages.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Fig. 1 is a block diagram showing the electrical system diagram of the household centralized monitoring device of the present invention. and an intercom, 6 a control circuit, 7 an alarm indicator consisting of an indicator light, a buzzer, etc., 8II'i handset,
9 represents a switch, and 10 represents an electromagnetic breaker for gas and electric alcohol, respectively.

FIG. 2 shows an external view of the central control and monitoring panel l shown in FIG. 1, and the same parts in both figures are represented by the same symbols.

When the sensors 2 to 4 detect an abnormality, an operation signal is sent to the alarm display 7 via the control circuit 6, which displays the alarm on the corresponding display and also sounds a buzzer or the like to notify the alarm of the abnormality.

When the intercom 5 is operated, a message to that effect is displayed and the intercom 5 is connected to the handset 8.

The switch 9 switches when each sensor 2 to 4 detects an abnormality.
Alarm stop switch (9-
i), ;b also shows a switch (9-3) that shuts off or restores the breaker 10 for gas, electricity, etc. by operating it when going out. In addition, if necessary, breaker IO
can also be controlled in conjunction with the operation signals of each sensor 2 to 4, and this breaker IO allows gas to pass through gas breakers and energizes electric breakers when electricity is turned on, and also to turn off power when the power is cut off due to power outages, etc. Sometimes closed circuits are used. However, this means that, for example, if there is a gas stove in use or a gas cooker with a pilot fire, and a short power outage occurs, the gas breaker 10 will temporarily cut off the gas, and then turn the gas on again. Since it was being restored, there was a drawback that raw gas would leak.

Because of this danger, conventionally, gas circuit breakers with a structure that mechanically locks when activated are sold, but these are expensive and are generally installed near the gas inlet outside. , it was inconvenient.

FIG. 3 is a diagram showing the main parts of a control circuit that solves these problems. In the figure, 9 indicates a non-lock switch for operating and disabling the breaker 1 [), and this switch 9 and a flip-flop 12 constitute a chattering prevention circuit, and each time the switch 9 is operated, a pulse is generated from the flip-flop 2 are sent out one by one. 13 is a D-type flip-flop, and each time a pulse is input to the clock terminal CK, the output terminal Q is inverted to H level and L level, and this output controls the transistor 15, which controls the relay A for controlling the circuit breaker IO. Control.

A capacitor 14 is connected between the reset terminal RK of the D-type 7 lip-flop 13 and ground, and this capacitor 14 is used to always set the output terminal Q to the L level when the power is disconnected and then turned on again. This D
The holding circuit 11 is composed of type flip-flops. Therefore, when the power is turned on to this device, the breaker 10, such as a gas breaker or an electric breaker (in this case, used mainly to cut off the power to an outlet), is forced into the cut-off state. There is. Therefore, switch 9
When operated, a pulse is applied to the clock terminal CK of the D-type flip-flop 13, the Q terminal thereof is set to H level, the transistor 15 is made conductive, and the relay A is driven.

As a result, the circuit breaker 10 is fully driven, and the lamp 7, which indicates that the circuit breaker 10 is in operation, lights up.

It should be noted that when the user wants to turn off the circuit breaker lO when going out, etc., it is preferable to operate the switch 9 again.

Furthermore, if the power supply is temporarily disconnected due to a power outage or the like, the circuit breaker 1O is kept in the disconnected state, and when the power is restored, the switch 9 can be operated again.

As described above, the home centralized monitoring device of the present invention has the advantage that it can easily control gas, electricity, etc. circuit breakers remotely, and there is no danger of temporary power cut-off due to power outages, etc. .
