INDUSTRIAL APPLICATION FIELD The present invention relates to a gas cutoff device for preventing gas accidents. BACKGROUND ART In recent years, gas has been widely used in homes, but one mistake can lead to a gas accident, so devices that ensure the safety of gas supply are becoming more important. An example of a conventional gas cutoff device will be described below with reference to FIG. In FIG. 3, 1 is a gas cutoff device, 2 is a gas meter, 3 is a flow rate sensor attached to the gas meter 2, 4 is an abnormality determination means, and 5, 6, and 7 are signals received from the flow rate sensor 3, respectively. This is the part that determines whether the abnormality is a large flow rate, a consumption pattern abnormality, or an alarm level abnormality based on the signal, and outputs a shut-off signal and a display information signal. Reference numeral 8 denotes a part that receives a signal from the external sensor 13 and outputs a cutoff signal and a display alarm signal when it determines that there is an abnormality. 9
1 is a shutoff valve that shuts off gas flowing as shown by the arrow based on a shutoff signal from the abnormality determination means 4;
0 is a display sorting means for dividing the plurality of display information signals from the abnormality determining means 4 into certain groups into distinguishable display categories; 11 is a display sorting means for lighting three LEDs 12 in response to a signal from the display sorting means 10; This is the display generation part to be performed. This display generating section 11 confirms the reason for shutting off the shutoff valve 9, alarm display, etc. An example is shown in the table below.

This increases the cost and power consumption of the LED itself and its drive circuit. In addition, when attempting to centrally manage this display, a device is required to collect the signals of all three LEDs, making it difficult to expand to central control. Means for Solving the Problems In view of the above problems, display classification means receives a plurality of display information signals outputted by the abnormality determination means as shutoff reasons and alarm indications, and divides the signals into distinguishable display categories different from conventional examples; Based on the display classification means, 1
The display device is provided with a display pattern generating means for performing a blinking dot display using each display element, and each category is distinguished by a time-series blinking dot pattern. Operation By setting a plurality of types of dot blinking patterns using the above means, it is possible to display a plurality of states with one display element. Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 and 2. Note that in FIG. 1, the same reference numerals as in FIG. 3 of the conventional example indicate the same components, and a detailed explanation will be omitted, and the explanation will focus on the different parts. Reference numeral 10' denotes a display sorting means for dividing a plurality of information signals from the abnormality determination means 4 into certain groups into distinguishable display categories, and 11' denotes a display sorting means 1.
One display element receiving the signal from 0'
Generates a dot blinking display pattern for LED12'.
This is display pattern generating means for blinking the LED 12'. FIG. 2 shows patterns A, B, C, and D grouped by the display dividing means 10' and the corresponding blinking dot display patterns A, B, and the LED 12'.
C and D are shown. Among these, a display pattern with the shortest flashing cycle is assigned to the indoor pipe leak in the alarm display.
In addition, as shown in Figure 2, by lighting (on) only at time T 1 and turning off at time T 2 and T 3 ,
The current consumption of the LED 12' of the gas cutoff device 1 is reduced.
Also, when the shutoff valve 9 is reset after the gas has been shut off, 2
A display pattern D for confirming a return leak, which indicates whether the gas appliance is open or closed, is set to pattern D, which has the shortest blinking cycle. Therefore, the end of the confirmation state after the shutoff valve has been reset can be notified earlier than other display patterns, and even if the gas shutoff device is installed in a location with poor visibility, the display can be overlooked. The possibility of misinterpretation can be reduced. Effects of the Invention The present invention with the above configuration has the following effects. (1) Since a plurality of blinking dot display patterns are performed using one display element, the cost and power consumption of LEDs, drive circuits, etc. can be reduced compared to the conventional configuration using three LEDs. (2) Since it is a single display element, it is easy to expand when centrally managed. (3) The intermittent time-series dot blinking display pattern reduces the power consumption of the gas cutoff device.
