  In the gas control system of the present invention, the centralized monitoring center can centrally control the group of gas control devices grouped under specific conditions, so that safety in a specific area can be improved.

  The first invention comprises a centralized monitoring center and a gas control device comprising a communication means for communicating with the centralized monitoring center, and the centralized monitoring of the group of gas control devices grouped under a specific condition The center is the central control.

  According to this, even in the case of a wide area disaster covering the entire specific area, the entire specific area can be controlled simultaneously.

  In the second invention, particularly in the first invention, the centralized monitoring center can arbitrarily set the specific condition for grouping according to the contents to be centrally controlled.

  According to this, when the assumed wide-area disaster is an earthquake, it is divided into areas with loose ground and stable areas. In the case of flood, river basin and hilly area are separated. In the case of a tsunami, the coastal area is classified. Also, when piping work is assumed, it is divided into areas where piping connections are common. Centralized control according to the situation becomes possible.

The third invention is the first invention or the second invention, in the event of a disaster or gas piping work,
The group of gas control devices in a specific area that are grouped together are controlled to be shut off or opened at the same time.

  According to this, in the event of a disaster, the safety of a specific area is improved, and prompt recovery after a disaster becomes possible. Moreover, at the time of construction, the work of closing and opening can be quickly performed without manpower.

  4th invention manages the information of each said gas control apparatus by the said centralized monitoring center.

  According to this, the centralized monitoring center can cope with the necessity of simultaneous control of the group of gas control devices grouped under specific conditions.

  According to a fifth aspect of the present invention, when the central monitoring center recognizes predictive information such as a disaster, the central monitoring center centrally controls the gas control device group grouped under specific conditions as necessary. .

  According to this, the necessary response can be quickly made to the necessary area according to the accurate disaster information from the public organization, regardless of the information from the individual gas control devices.

  In the sixth aspect of the invention, a sensor for detecting information necessary for centralized control is not provided in each of the gas control devices, but is provided only in a specific gas control device at a location as required. .

  According to this, since the detection sensor can be provided only in a necessary place, the cost of each gas control device can be reduced.

  According to a seventh invention, in the first to sixth inventions, the communication between the centralized monitoring center and the previous gas control device is performed by wireless communication.

  According to this, since it is possible to perform emergency communication using dedicated wireless communication without using a public line such as a telephone, it is possible to avoid a disconnected state due to communication congestion at the time of a disaster. Safety can be improved without further congesting the public line.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiment.

(Embodiment 1)
FIG. 1 is a diagram showing a gas control system according to the present invention. This system includes a central monitoring center 1 and gas control devices 3 to 7 (representative examples).

  The centralized monitoring center 1 performs centralized control of the gas control devices 3 to 7 arranged in areas A to C where wireless communication from the communication base station 2 is possible.

  Here, in order to simplify the explanation, the number of gas control devices is limited to five as a representative example, but a system that can cover all households in a communicable range is actually assumed.

For example, area A is a ground where the ground is loose and damage is expected in the event of an earthquake, area B is a river basin where flood damage is expected in case of heavy rain, and area C is a coastal coastal area where a tsunami occurs If the area is assumed to be an area, the central monitoring center 1 is assumed to be an earthquake danger area and the gas control device 3
, 6, and 7 are registered as gas control devices 5, 6, and 7 as flood hazard areas, and the gas control devices 4 and 7 are registered as tsunami risk areas. The central monitoring center 1 constantly monitors disaster information from the public organization 8, and when earthquake information is obtained, the communication base station 2 informs the A area about the gas cutoff command and the earthquake cutoff. In addition, information necessary for consumers who have installed gas control devices such as the magnitude of earthquakes and earthquake source information is transmitted. When flood information and tsunami information are obtained, necessary information is transmitted to the B area and C area, respectively.

  In the case of this example, the gas control device 7 appropriately responds with the information from the centralized monitoring center 1 regardless of the information of earthquake, flood or tsunami. The gas control device that has received information from the central monitoring center 1 via the communication base station 2 displays information that needs to be shut off or notified in accordance with the information on the display terminal of the consumer. For example, in the case of an earthquake, if the centralized monitoring center 1 transmits information using P-wave information from the public institution 8, it is possible to carry out prompt disaster prevention.

  The centralized monitoring center 1 changes the settings of each region according to changes in surrounding conditions, for example, ground improvement and revetment construction, and appropriately changes and operates them as needed. In addition, when the gas piping connection is common between the A area and the B area, when performing gas work in the B area, the central monitoring center 1 through the communication base station 2 for both the AB areas. In advance, the prior information on the interruption by construction is displayed in advance on the display terminal of the customer who has installed the gas control device, thereby avoiding the confusion of sudden gas interruption due to the construction. According to this, it is possible to reduce the cost of prior contact by mail.

  In addition, when the central monitoring center 1 constantly monitors sensor information from each gas control device and analyzes the information from each gas control device and determines that it is involved in the entire specific region, An appropriate treatment instruction is transmitted via the communication base station 2. For example, if seismic information from an individual gas control device is received at a predetermined rate or more in a specific area, it is possible to respond by sending a gas shutoff command to that area all at once. It becomes. If the seismic information from the gas control device is specific to a certain consumer, it is determined that it will not spread to the entire area as single-shot impact information on the gas control device of a specific customer, and individual confirmation work is performed. It is possible to cope with it.

  Also, in general, if various sensors such as seismic devices equipped in all gas control devices are installed, and gas control devices with sensors are installed at appropriate locations in each region, the necessary regional information is centrally monitored. Since the center 1 can monitor, the cost of the whole gas control apparatus of the whole area can be reduced, without reducing safety.

  In addition, when information cannot be transmitted to a necessary area only by the communication base station 2, if the number of base stations is increased as necessary, such as the communication base station 9, the area where the information can be transmitted can be arbitrarily expanded.

  As described above, according to the present embodiment, even in the case of a wide-area disaster covering the entire specific area, the entire specific area can be controlled simultaneously, so that the safety of the entire specific area can be improved. it can.

  However, since the central monitoring center determines whether it affects the entire area or should be dealt with individually, it does not inadvertently shut off the gas in the entire specific area, so the impact on consumers is minimized. Can be suppressed.

Incidentally, in the embodiment, the communication between the centralized monitoring center 1 and each gas control device has been described by wireless communication via the communication base station 2, but there is no possibility of congestion or a special short-circuit. In the case of time communication, information may be transmitted by communication using a public line.

  In the embodiment, the disaster information from the public organization 8 is constantly monitored. However, the centralized monitoring center 1 can independently determine and analyze the disaster information from various weather information.

  Although various embodiments of the present invention have been described, the present invention is not limited to the matters shown in the above-described embodiments, and those skilled in the art may modify or apply the description based on the description of the specification and well-known techniques. The present invention is intended to be included in the scope for which protection is sought.

  According to the gas control system of the present invention, since the entire specific area can be controlled at the same time, the safety of the entire specific area can be improved.
