Description

  The present invention relates to a gas shut-off device, and more particularly to event occurrence date and time recording.

As for the thing which records the event at the time of interception with this kind of conventional gas interception device, what was shown in patent documents 1 was common. These can set time and the like by two-way communication, and can record the time when an event occurs by providing a calendar function or the like inside.

Even in an inexpensive gas shut-off device, as shown in Patent Document 2, the date and time of an event is recorded by a method in which a counter is provided and counted from the occurrence of the event.
Japanese Patent No. 1923508 Japanese Patent No. 3642663

  However, many inexpensive gas shut-off devices do not have information communication means with a large amount of information, and it is difficult to set the time at the assembly stage in the factory. Even when the internal time is set by the communication means, there is a problem such as maintenance that periodically corrects the time because the internal clock has an error.

  In order to solve the above problems, the present invention provides a radio wave receiving unit for receiving radio waves in the gas cutoff device, periodically receives standard radio waves or GPS signals, and performs time setting and correction.

  According to the above invention, it is possible to record an accurate time when an event occurs, and it is easy to assemble and maintain because there is no need for setting and correction from the communication means or the like.

  As described above, according to the gas cutoff device of the present invention, there is an effect of accurately recording the time when the event occurs by receiving the radio wave. In addition, by receiving GPS radio waves, it is possible to record the position data of the gas shut-off device, and to analyze the distribution of local shaking and the temperature situation such as when an earthquake occurs.

According to a first aspect of the present invention, there is provided a radio wave receiving unit that receives a GPS signal, a recording unit that records data including position data received by the radio wave receiving unit, a valve, a flow rate input unit, a control unit, and a notification unit. having a communication unit, a timer unit that counts elapsed time from reception by the radio receiver,
Wherein, when the event has occurred, and recording the count value counted by both the timer unit and data received last time recorded the radio receiver in the recording unit in the recording unit It is a gas shut-off device, and it is possible to accurately record the time when the event occurred.

The second invention is the first invention, vibration detection unit has a of both the timer unit to the data including the position data received in the data recording unit previously received by the radio receiver if the events by vibration occurs A gas shut-off device that records the count value. When an earthquake occurs, it records the position data of the gas shut-off device using GPS signals, and is used for analysis of shaking and damage status at the time of the earthquake. It becomes possible to do.

(Embodiment 1)
FIG. 1 is a block diagram of a gas cutoff device according to Embodiment 1 of the present invention.

  With reference to FIG. A flow rate is detected from the flow rate input unit 1 and a flow rate signal N1 is output to the control unit 2.

  When the control unit 2 receives the flow rate signal N1, it determines whether the flow rate is an arbitrarily set flow rate, and outputs a valve closing output signal N2 to the valve 3 if it exceeds the set flow rate.

  When the valve 3 receives the valve closing output signal N2, the valve is closed.

  The control unit 2 outputs a signal to the valve 3 and receives from the timer unit 5 a data signal N3 previously received from the radio wave receiving unit 4 and a count value N5 counted from the time when the signal is received from the radio wave receiving unit 4. The event data is recorded in the recording unit 6. It is assumed that the data of the recording unit 6 can be communicated to the outside by the communication means 7. Further, the control unit 2 receives the vibration detection signal N10 from the vibration detection unit, and the control unit 2 counts the event from the data signal N3 received from the radio wave reception unit 4 and the timer unit 5 as an event. The value N5 is received and recorded in the recording unit 6. When the control unit 2 transmits the temperature measurement signal N12 to the temperature measurement unit 10, the control unit 2 receives the temperature measurement result signal N12 from the temperature measurement unit 10, and the control unit 2 receives the recording unit 6 from the radio wave reception unit 4. The received data signal N3 and the count value N5 from the timer unit 5 are received and recorded in the recording unit 6. When an event occurs, the control unit 2 outputs a notification signal N11 to the notification means 9 to notify the outside. The radio wave received by the radio wave receiver is a standard radio wave or a GPS signal.

  As described above, the gas shut-off device according to the present invention can record the time by using a standard radio wave or a GPS signal. It can also be applied to uses such as recording time.
