It is connected to the monitoring device 20 via a cable laid along the vacuum sewer pipe 6.

The monitoring device 20 monitors the normal / abnormal condition of the sewage water level, the open / closed state of the vacuum valve, the number of times of operation, etc., so that the abnormality / failure of the vacuum valve can be detected early.

In addition, in recent years, in rural areas, etc.,
The number of buildings and houses where the elderly living alone live is increasing. For example, grasp the pattern of life from the usage situation of the toilet,
When an abnormality is detected, it is known that even an elderly person living alone can lead a safe life by confirming his / her safety by using a life abnormality sensing device that notifies a security management company or the like (for example, Patent Document 2). reference.).

In such a life change sensing device, a temperature sensor for measuring body temperature is newly added to a toilet in a building house.
Various sensors such as a load sensor, a human body detection sensor, or a water flow sensor are provided, and a communication line must be separately laid or a telephone line must be laid between the security management company and the security management company. There was a problem that the cost would increase.

The updated and stored collation data is compared.

At this time, for example, like the case where the vacuum valve 4 was regularly opened and closed until yesterday, if the vacuum valve 4 is opened and closed, the comparison is in agreement, so the process returns to Step 2 and the detection data acquisition is continued. In addition, even if the vacuum valve 4 was regularly opened and closed until yesterday, but the opening and closing of the vacuum valve 4 suddenly stopped, it is possible to use the above water supply facility for a resident living alone. If it is determined that some other reason has occurred, the process proceeds to Step 6.

At Step 6, the safety judgment means 130 transmits the monitoring result indicating that the elderly living alone are in danger to the management department such as the sewerage department 133 via the interface 24 and the telephone line 132.

In the management department such as the sewerage department 133, this monitoring result is received via the interface 133a,
It is output and displayed on the screen of the personal computer 133b.

Further, this monitoring result is transmitted and output to the dirty water mass 2 through the interface 24 and the cable 23. In response to this monitoring result, the terminal controller 22 of the dirty water mass 2 turns on the red light emitting portion 17a provided in the vent pipe 17.

As described above, since the valve sensor 19 for detecting the opening / closing of the vacuum valve 4 which is performed several times a day by using water around the water, which is indispensable for daily life, the elderly living alone, etc. are selected depending on the frequency of opening / closing of the vacuum valve 4. You can check the safety of the residents of the building.

Further, since the vacuum valve 4 is opened and closed at the time when a predetermined amount of dirty water is accumulated in the dirty water mass 2, minute fluctuations on a daily basis are absorbed, and the risk of false notification can be reduced. .

The water level sensor 19 also detects the amount of accumulated sewage, and the fluctuation of the accumulated amount causes
You can check the safety of the residents of buildings such as the elderly living alone.

Therefore, it is not necessary to newly place various sensors in the building house 1 for confirming the safety, and
Since the detection data can be transmitted and received by using the existing line such as the existing cable 23 that connects the sewage mass 2 to the vacuum station 7, it is possible to suppress the increase of additional work and utilize the existing infrastructure. Can reduce the cost.

Since the safety judgment means 130 judges the safety of the resident of each building or house based on the detection data of the time zone, the structure of the resident of the building or house can be individually dealt with.

Further, since the verification data stored in the verification data storage unit 126 is sequentially updated by using the detection data, it is possible to always use the data according to the latest usage condition as the verification data. The monitoring accuracy can be improved.

The vacuum station 7 is controlled by a monitor terminal such as a personal computer 133b provided in a management department 133 such as a municipal office, a fire station, a police station, etc., including a sewer station located in a place separated from the vacuum station 7. The monitoring result of the safety by the monitoring device 120 can be monitored.

Therefore, it is not necessary to allocate personnel to each of the vacuum stations 7 and 7, and the plurality of vacuum stations 7 and 7 can be centrally managed by the management department 133.

Therefore, even when there are scattered building houses 1 ... Which need to be monitored, it is possible to monitor the safety of the home while suppressing the rise in personnel costs. Therefore, it can be used as a safety monitoring system for rural areas. Is suitable.
