Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a centralized safety shutoff and alarm device for detecting and shutting off abnormal gas outflows to maintain gas safety and providing an external display.

The configuration of a conventional example and its problems A conventional gas safety shutoff notification system is shown in FIG. The main body of the 1-kehono security system J has an interfon 2 and a slave unit 3.41 for the interfon terminal. In addition, security alarm notification display group 6 (display a
,b,...e) and alarm buzzer 6? Fire alarm 7
, input the outputs from the intrusion detector 8, gas leak alarm group 9, 10.
5 to display each input status and operate the alarm ZOZA-6. Gas leak alarm 9.10.11 has external outputs 12, 13,
14 (dimensions used, ink-fe-s 15, 16
．． 17, one is connected to a shutoff controller 18 installed outdoors, and a shutoff valve 19 is used to control the gas flow path. is closed. The shutoff controller 18 has a shutoff display 1.
It has 8a. Also, gas leakage, alarm 9, 10.11
includes light emitting elements 20, 21° 22 and alarm buzzers 23, 2.
4 and 25 are each equipped.

The disadvantage of the conventional example is that the use of a gas leak alarm to connect the security system increases the number of indoor wiring and complicates the construction work. In addition, since it is necessary to use an external output of 1:1 as the gas leak alarm DG, when introducing a home security system into a home that already has a gas leak alarm installed (compatible with the existing installation). , it is also necessary to replace the external output with 1 alarm k.

Next, as a second conventional example of an IC, if a microcomputer is incorporated into a gas meter and an abnormal gas flow rate occurs, the gas flow path is completely closed using a shutoff valve installed inside the gas meter.
There is a microcomputer meter system that emits light externally such as D. Figure 2 ((An example of this system is illustrated. This system displays the shutoff inside the gas valve (gas meter), but the reason for the shutoff cannot be known unless you go to the gas meter. In Figure 2, 26 is the gas meter main body, which includes a shutoff valve 27, a battery 28, a microcomputer 29, a usage flow rate display 30, an LED display section 31 indicating the reason for shutoff, and an external sensor terminal lead wire 3.
2. The external mounting is configured to be equipped with a sensor group such as a vibration sensor 33 as a sensor. In addition, 34 is a gas supply pipe, 35 is a gas pipe supplied to each appliance, 36 is a gas staple stove, 37 is a water heater, and 38 is a bath kettle. With the conventional example shown in Figure 2, the flow rate determination allows the microcomputer 29 attached to the gas meter to determine the usage status of each individual appliance without having to equip each individual appliance or room with a group of gas leak alarms. The logic can be memorized and identified, but the biggest drawback is that the cause of the cut-off cannot be understood unless it is in the meter section.

OBJECTS OF THE INVENTION The present invention provides a system that centrally displays shutoff safety operation information as an alarm for home security in a system with high operational reliability.

Structure of the Invention The present invention detects shutoff information or gas leak information L1
11, in addition to receiving the light with a photo sensor and electrically isolating it, it is also possible to upgrade the safety system after installation or replace each existing safety alarm means even if it is combined with home security. The purpose is to configure a light-receiving element unit with a built-in photosensor so that it can be used even without a photo sensor.

DESCRIPTION OF THE EMBODIMENTS FIG. 3 is one of the embodiments corresponding to the conventional example shown in FIG. 1, and the same functional parts as in the conventional example are designated by the same numbers f-=t. The special envoy in Figure 3 receives the lighting of display LED 20.21.22 marked n1 from outside the box of the gas leak alarm at display LED 20.21.22 of each gas leak alarm 9.10.11. ] 1st: Light receiving element unit 1 containing a built-in sensor
-39.40.41 1j, each lead wire 4
At 2.43.44, the input and output lead wires 45, 46, and 47 to the shutoff controller 18 are connected to the home security to activate the alarm and notification display group 571i.

FIG. 4 shows another embodiment, and the difference from FIG. 3 is that the shut-off display is connected to the home security main body 1, and the shut-off display LED 9a is connected from the outside of the box of the shut-off controller 18.
In this example, the light receiving element unit 48ff is connected to the home security main body 11/l by the lead wire 491 to receive the lighting of the light receiving element unit 48ff.

FIG. 5 shows an embodiment corresponding to FIG. 2 of the conventional example. The light receiving element Konnit 50 receives the light emitted from the cut-off display LED 31 by the microcomputer 29 installed in the customer meter 26,
Connect to the home security main body 1 with a lead wire 51.

Light receiving element unit) This is a unit that is installed from outside the box of the 50U ma/rcon meter.

Effect of the invention As described below, according to the present invention, the following effects can be obtained.

(1) Call function and alarm display function? In order to connect various gas shut-off safety devices to the home security system that has a gas shut-off safety device, it requires less wiring than the conventional method of electrically connecting by receiving all the output light from the shut-off display section of the gas shut-off safety device. The optical coupling section insulates and isolates the effects of component failures caused by cable routing noise and lightning surges, which can harm the entire system, ensuring operational stability.

(2) Photodetector unit? Since the gas cutoff safety device will be removed from the outside in 11 days, it will be necessary to change to a microcomputer meter circuit breaker that is integrated with the already installed gas leak alarm, gas make, etc., or to replace it. First, it becomes possible to combine that talent with home security.

(3) As home security that receives the output of the light receiving element unit, when shutting off, light emitting state, flashing state, audio notification,
Since alarm buzzers, etc. can be added to [4], it is convenient to be able to identify the reason for shutting off at a concentrated point.
