JP2000081198A - Dummy indicator for gas meter emergency trip display - Google Patents

Abstract

PROBLEM TO BE SOLVED: To illustrate the emergency trip of a gas meter or the content of an alarm display so as to be easy for a user of gas to understand by controlling a dummy display lamp so as to be flashed in the same flashing pattern as the flashing part pattern of flashing the display lamp of an actual gas meter. SOLUTION: An optional emergency trip cause/alarm reason selection switch 2 is pressed, whereby a dummy display lamp 4 is flashed in a pattern corresponding to the operated switch 2. In case of a switch 21 having 'seismoscope, pressure reduction' printed nearby, when the emergency trip valve of the gas meter is cut because of the signal input from a seismoscope or pressure switch built in the gas meter or an externally provided gas leakage alarm, the dummy display lamp is flashed in the same pattern as the actual flashing of the display lamp of the actual gas meter. Accordingly, the emergency trip of the gas meter emergency trip valve or content of alarm display displayed by the flashing of the display lamp can be illustrated so as to easy for a user of gas to understand.

The blinking pattern displayed by the indicator lamp 40 of the gas meter B blinking is determined by the cause of the shut-off of the shut-off valve or the reason of the alarm. The first pattern that indicates the case where there is a signal input from a pressure switch or an externally provided gas leak alarm, the cause of the gas interruption is that the gas continues to flow for an abnormally long time without fluctuation in the gas flow rate. A second pattern indicating that the gas flow has occurred, indicating that the gas has been interrupted because the flow rate of the gas flowing through the gas meter has exceeded a predetermined capacity, or after returning the shutoff valve which has been shut off. A third pattern indicating that the gas flowed within a minute, not a shut-off, but a gas that was confirmed to be leaking for 2 minutes after returning the shut-off valve, or for which gas flow was observed for 30 consecutive days. There are fourth pattern four pattern showing a case where over data is moving even a little, therefore, also four blocking Cause and alarm reason selection switch 2 (21,22,23,2
4) Provided.

Is detected or stopped, and the information is sent to a blinking pattern generation circuit 53.
And to the timer circuit 52 as a signal. When the switch operation detection circuit 51 confirms the operation of the switch 2 for selecting the cause of interruption and the reason for alarm, the switch operation detection circuit 51 supplies power to the lamp 7 of the switch 2 to turn it on.

The timer circuit 52 reflects the time on a simulated lamp display because the actual gas meter B performs a leak confirmation operation for 2 minutes after the return button 30 is pressed. After switch 3 is operated, 2
After a minute, a stop signal is sent to the blinking pattern generation circuit 53. Note that the time until the stop signal is generated after the operation of the return switch 3 can be changed, and the time can be arbitrarily set to about 20 seconds in order to reduce the time required for explanation.

The blinking pattern generation circuit 53 stores blinking signals corresponding to the four patterns. When a selection signal of any one of the four patterns is input from the switch operation detecting circuit 51, the blinking pattern generation circuit 53 stores the signals in advance. The corresponding one of the four blinking signals is sent to the display control circuit 54.
When a stop signal is input from the timer circuit 52, the transmission of the blink signal to the display control circuit 54 is stopped.

The display control circuit 54 includes a blinking pattern generation circuit
On / off control of the power supply to the simulation display lamp 4 is performed based on the blink signal sent from 53, so that the simulation display lamp 4 blinks.

Therefore, according to this embodiment, when the switch 2 for selecting the cause of interruption / alarm is pressed, the simulated display lamp 4 blinks in a pattern corresponding to the operated switch 2. In other words, if the operated shut-off cause / alarm reason selection switch 2 is a switch 21 in which “SENSITIVE, PRESSURE DOWN” is printed and displayed in the vicinity thereof, the shut-off valve of the gas meter B is replaced with the built-in When the signal is shut off due to a signal input from a gas leak alarm device provided externally, a pressure switch, or an external gas leak alarm device, the display lamp 40 of the actual gas meter B blinks in the same pattern as the actual blinking. When the return switch 3 is pressed, the blinking stops after 2 minutes. FIG. 3 is a flowchart showing the operation of the simulation display device according to the present embodiment.
