No. 2 vacuum valve unit 1 in which an abnormality occurred
After the pressure has been restored and the vacuum pressure has recovered within the specified range, the operation returns to the normal operation. That is, when the sewage water level rises above the specified value, it is displayed on the monitor 7a of the personal computer 7 of the vacuum station 9 and notified to the management section 16 through the telephone line 10, and is displayed on the monitor 15a of the personal computer 15 of the management section 16 as " No. ・ ・ The wastewater level is abnormal with the vacuum valve unit. ”

Whether the vacuum valve unit in which the abnormality has occurred has been restored is determined in the following state. In other words, if the vacuum valve of the vacuum valve unit was open before restoration, it is determined whether or not it was closed.If the abnormality before restoration was the sewage water level abnormality, whether the sewage water level dropped to the specified value Judge by whether or not. As mentioned above, although one Embodiment of this invention was described in full detail, this invention is not limited to the said Embodiment, It deviates from the spirit of this invention described in the claim in design. Various changes can be made without.
