DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for monitoring a vacuum valve unit (sewage masturbation) in a vacuum type sewer system, and more particularly to storing sewage discharged from a building in a vacuum valve unit and using the sewage as a vacuum sewer pipe. The present invention relates to a monitoring device for monitoring a vacuum valve unit in real time in a vacuum type sewerage system for transferring to a sewage treatment plant or the like.

[0002]

2. Description of the Related Art In a vacuum type sewer system, sewage discharged from a building such as a general household is stored in a vacuum valve unit (sewage masturbator), and the sewage is vacuum pressure (negative pressure) generated in a vacuum station (sewage treatment plant). This is a sewage system that suctions by pressure and transports it to a vacuum station.

[0003] In a vacuum valve unit of this type of vacuum type sewer system, when a sewage water level abnormality of a sewage tank occurs due to a vacuum valve failure or the like, it is necessary to quickly detect this and notify a manager. As such an abnormality detection system, as disclosed in Japanese Utility Model Laid-Open No. 4-92087, an alarm device is installed near a vacuum valve unit,
In some cases, when an abnormality occurs in the vacuum valve unit, the abnormality is notified by voice, light, display characters, or the like of the alarm device.

[0004]

In the above-described conventional abnormality detection system, an alarm device is installed for each vacuum valve unit. Therefore, when an abnormality occurs due to a certain vacuum valve unit, the abnormality is detected. Not only did it take time and effort to identify the vacuum valve unit that caused the problem, but there was a problem that it was necessary to support the residents to inform the administrator. Moreover, since the above-mentioned alarm device is independent for each vacuum valve unit, it is necessary to incorporate a battery as a power source for each alarm device, and it is necessary to replace the battery according to the battery life, which makes maintenance complicated. There was also a problem.

The present invention has been made in view of such a problem, and an object of the present invention is to make it possible to monitor each vacuum valve unit in real time by a management department, to eliminate the need for a battery as a power source, and to maintain To provide a monitoring device for a vacuum valve unit in a sewage system which facilitates the above.

[0006]

In order to achieve the above object,
A monitoring device for a vacuum valve unit in a sewer system according to the present invention stores sewage discharged from a building in a vacuum valve unit (sewage masturbator) and utilizes the stored sewage by utilizing a vacuum pressure generated in a vacuum station. In a sewer system that is transported to a vacuum station by an underground vacuum drain,
In the vacuum valve unit, a sensor that detects the state inside the vacuum valve unit and a terminal that transmits the detection information of the sensor are installed, the terminal is connected to the cable laid along the vacuum sewer pipe, and one end of the cable is evacuated. It is characterized in that it is connected to a monitoring system installed in the station, and that information is transmitted from the monitoring system to a management department via a telephone line.

As a specific embodiment of the monitoring device for the vacuum valve unit, the monitoring system installed in the vacuum station includes a personal computer, an interface unit of the personal computer, and a modem for connecting to a telephone line. The administration department has a modem and a personal computer connected to the telephone line. Further, the sensor detects the open / closed state of the vacuum valve of the vacuum valve unit, the number of times the vacuum valve is operated, and whether the water level in the vacuum valve unit is normal or abnormal. Sensors and terminals are powered by cables from the vacuum station.

In the monitoring apparatus for the vacuum valve unit in the sewage system according to the present invention configured as described above, information in the vacuum valve unit is constantly sent to the vacuum station via a sensor, a terminal, and a cable. . Therefore, the monitor of the personal computer in the vacuum station
The status of the vacuum valve unit (opening / closing status of the vacuum valve, number of times the vacuum valve is operated, normal / abnormal sewage water level, etc.) is displayed in real time.

If the water level rises abnormally at a certain vacuum valve unit, the state is transmitted in the order of sensor, terminal, cable, interface unit, and personal computer, and is displayed on the monitor of the personal computer. Further, the information of the vacuum valve unit is transmitted to the management section via a telephone line by a modem, and is displayed on a monitor of a personal computer in the management section. If you want to know the status of the vacuum sewer system, make a phone call from the personal computer of the administrative department and connect it to the personal computer of the vacuum station. The monitor of the personal computer of the administrative department will display exactly the same information as the personal computer monitor of the vacuum station. Thus, the state of the vacuum valve unit can be grasped in real time.

If a portable personal computer is used, not only from the management section 16 but also from the public telephone 1 as shown in FIG.
2. A mobile telephone 13 or a telephone at the manager's home can be connected to the personal computer 7 of the vacuum station 9 via the telephone line 10 so that the status of the vacuum sewer system can be known from anywhere. 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.

For example, when an abnormality occurs in the sewage water level or the opening / closing operation of the vacuum valve, it is also possible to issue an audio alarm together with the monitor display of the personal computers 7 and 15.

[0019]

As can be understood from the above description, the monitoring apparatus for the vacuum valve unit in the sewage system according to the present invention displays the status of all the vacuum valve units on the personal computer of the vacuum station and sends it to the management department via telephone line. Since the information is transmitted, the status of the sewer system can be grasped in real-time by the management department, and which vacuum valve unit has an abnormality can be immediately identified.In addition, the display contents include sewage water level abnormality, vacuum valve opening / closing abnormality, etc. Since the number of times of operation of the vacuum valve can be displayed collectively, a maintenance schedule can be easily set, and the vacuum valve unit can be efficiently managed.

Further, since the power to the sensor and the terminal of each vacuum valve unit is supplied from the vacuum station through a cable, each vacuum valve unit does not require a power source such as a battery and does not require maintenance such as battery replacement.
