Description

【０００１】
【発明の属する技術分野】
本発明は、ガスの検針を行うガス計量遮断装置に関するものである。
【０００２】
【従来の技術】
従来のこの種のガス計量遮断装置を、図１４の機能ブロック図を用いて説明する。なお、その構成については図４を参照するものとして説明する。図においてガス流量検出部１が検出したガス流量をガス計量部２が積算してガス使用量を指針値として保持し、制御部３が検針日時保持部４が保持している検針日時とタイマー部５が計測している現在日時の比較を行い、一致した時に指針値を通信部６を介して集中管理センター７などの外部へ送信し、遮断日時保持部８が保持している遮断日時とタイマー部５が計測している現在日時の比較を行い、一致した時にガス遮断弁９を閉栓し、開栓禁止状態保持部１０の前記開栓禁止状態に開栓禁止をセットすることにより開栓入力部１１あるいは通信部６を介して集中管理センター７などの外部から入るガス遮断弁８の開栓命令を実行しないようにしていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、従来のガス計量遮断装置では、ガスの利用者が引越しなどのために契約を解除する際に、通信部６を通して契約解除日時を検針日時保持部４の検針日時と遮断日時保持部８の遮断日時の両方に重複して設定しなければならないため、集中管理センター９からガス計量遮断装置への設定のための通信時間が長くなるという第一の課題を有していた。
【０００４】
また、検針日時保持部４の検針日時を遮断日時保持部８の遮断日時より前の日時に設定し電話回線が使用可能な内に通信部６を通して集中管理センター７に指針値を送信して、利用者が引越しをしてガスを使用する可能性がなくなった後にガス遮断弁９を閉栓しガスを遮断するようにしていた場合、指針値送信からガス遮断弁９の閉栓までにガスを無制限に使用できるため、指針値送信後の追加のガス使用量の請求ができないという第二の課題を有していた。
【０００５】
また、遮断日時保持部８の遮断日時を検針日時保持部４の検針日時より前の日時に設定し、ガス遮断弁９の閉栓によりガスが利用できないようにして指針値が変化しないようにしてから指針値を通信部６を通して集中管理センター９へ送信しようとした場合、引越しに伴いガス計量遮断装置と集中管理センター９を結ぶ電話回線が不通になれば指針値を送信できなくなるという第三の課題を有していた。
【０００６】
また、遮断日時保持部８の遮断日時を検針日時保持部４の検針日時より前の日時に設定してガス遮断弁９の閉栓後に利用者が緊急でガスを使用したいという場合、引越しに伴いガス計量遮断装置と集中管理センター９を結ぶ電話回線が不通になっていれば、集中管理センター９からの遠隔操作によるガス遮断弁９の開栓が行えないため、作業員を派遣してガス遮断弁９を開栓しなければならなくなるという第四の課題を有していた。
【０００７】
【課題を解決するための手段】
本発明は上記の第一の課題を解決するために、ガス計量部がガス流量検出部で検出したガス流量を積算して指針値を保持し、制御部がタイマー部で計測している現在日時と検針日時保持部で保持している検針日時を比較し一致した時に遮断検針命令を発生し、遮断検針命令によりガス遮断弁を閉栓し、ガス遮断弁の開栓を禁止し、ガス計量部で保持している指針値を通信部を用いて送信するものである。
【０００８】
上記発明によれば、検針日時を一つだけ設定すれば契約解除に伴うガス遮断弁の閉栓と指針値の送信を行うことができ、集中管理センターからガス計量遮断装置への検針日時の通信による設定時間を短くできる。
【０００９】
【発明の実施の形態】

【００１０】
そして、検針日時保持部に保持した検針日時だけでガス遮断弁の閉栓と指針値の送信を行うため、集中管理センターからガス計量遮断装置の検針日時保持部にに設定する検針日時だけを送信すればよいため設定時間を短くすることができる。
【００１１】

【００１５】

BACKGROUND OF THE INVENTION
The present invention relates to a gas metering cutoff device that performs gas meter reading.
[0002]
[Prior art]
A conventional gas metering cutoff device of this type will be described with reference to the functional block diagram of FIG. Note that the configuration will be described with reference to FIG. In the figure, the gas flow rate detected by the gas flow rate detection unit 1 is integrated by the gas metering unit 2 and the gas usage is held as a guide value, and the control unit 3 holds the meter reading date and time and the timer unit. 5 compares the current date and time measured, and transmits a guideline value to the outside such as the central management center 7 via the communication unit 6 when they match, and the cutoff date and time held by the cutoff date holding unit 8 and the timer Comparing the current date and time measured by the unit 5, the gas shut-off valve 9 is closed when they match, and the opening is prohibited by setting the opening prohibited state to the opening prohibited state of the opening prohibited state holding unit 10. The opening command of the gas shut-off valve 8 entering from the outside such as the central control center 7 through the unit 11 or the communication unit 6 is not executed.
[0003]
[Problems to be solved by the invention]
However, in the conventional gas metering shut-off device, when the gas user cancels the contract for moving or the like, the contract cancellation date and time are set to the meter reading date and time of the meter reading date and time holding unit 4 and the shut-off date and time holding unit 8 through the communication unit 6. Since it has to be set to both the shut-off date and time, there is a first problem that the communication time for setting from the central control center 9 to the gas metering shut-off device becomes long.
[0004]
In addition, the meter reading date and time of the meter reading date and time holding unit 4 is set to a date and time before the shutting date and time of the blocking date and time holding unit 8, and the pointer value is transmitted to the central control center 7 through the communication unit 6 while the telephone line is usable. If the gas shutoff valve 9 is closed and the gas is shut off after the user has moved and no longer has the possibility to use the gas, the gas is unlimited from the transmission of the guideline value to the closing of the gas shutoff valve 9 Since it can be used, there was a second problem that it was not possible to request an additional gas usage after the guideline value was transmitted.
[0005]
Also, after setting the shut-off date / time of the shut-off date / time holding unit 8 to a date / time before the meter-reading date / time of the meter-reading date / time holding unit 4, the gas shut-off valve 9 is closed so that the gas cannot be used and the pointer value does not change. The third problem is that when an attempt is made to transmit the guideline value to the central control center 9 through the communication unit 6, the guideline value cannot be transmitted if the telephone line connecting the gas metering cutoff device and the central control center 9 is disconnected due to moving. Had.
[0006]
If the user wants to use gas urgently after closing the gas shut-off valve 9 by setting the shut-off date / time of the shut-off date / time holding unit 8 to a date / time before the meter reading date / time of the meter-reading date / time holding unit 4, If the telephone line connecting the metering shut-off device and the central control center 9 is disconnected, the gas shut-off valve 9 cannot be opened by remote control from the central control center 9, so a worker is dispatched to send the gas shut-off valve. The fourth problem was that 9 had to be opened.
[0007]
[Means for Solving the Problems]
In order to solve the above first problem, the present invention integrates the gas flow rate detected by the gas flow rate detection unit, holds the pointer value, and the control unit measures the current date and time. And the meter reading date and time held in the meter reading date and time holding part, the shut-off metering command is generated when they match, the shut-off metering command is used to close the gas shut-off valve, prohibit the gas shut-off valve from being opened, and the gas metering part The stored pointer value is transmitted using the communication unit.
[0008]
According to the above invention, if only one meter reading date and time is set, the gas shut-off valve can be closed and the guideline value can be transmitted when the contract is canceled, and the meter reading date and time can be communicated from the central control center to the gas metering shut-off device. Setting time can be shortened.
[0009]
