Description

The present invention relates to a drainage system and a server device.

The drainage system is roughly divided into a gravity type drainage system and a vacuum type drainage system. The gravity type drainage system is a system that drains sewage etc. by utilizing the natural flow due to gravity, and the vacuum type drainage system uses a vacuum pump to keep the inside of the pipe in a negative pressure state and the pressure inside the pipe. It is a system that forcibly drains sewage etc. by using the pressure difference between the pressure and the atmospheric pressure. Since the gravity type drainage system utilizes the natural flow due to gravity, it requires a downward slope that continues in the downstream direction, whereas the vacuum type drainage system requires the pressure in the pipe and the atmospheric pressure. Since the difference is used, a downward slope is not always required, and it is possible to drain water even with a reverse slope.

The following Patent Document 1 discloses an example of a conventional vacuum type drainage system. Specifically, in Patent Document 1 below, it is possible to stop the drainage of sewage in a state where the liquid level height of the sewage is higher than one end of the suction pipe, and the suction of gas such as air at the time of drainage is performed. A drainage system is disclosed in which noise and vibration of pipes are suppressed by avoiding and sucking and draining only a liquid.

By the way, one of the above-mentioned vacuum type drainage systems is equipped with a water collecting tank for collecting sucked sewage and a pressure pump for pumping sewage in the water collecting tank to the outside, and the water collecting tank is filled with water. There is a system that controls the pump to prevent it from becoming. In such a drainage system, for example, based on the detection result of a liquid level sensor (a sensor that detects the liquid level of sewage or the like) provided in the water collecting tank, a pump is pumped in advance before the water collecting tank becomes full. By pumping sewage to the outside, the water collection tank is prevented from becoming full.

However, even in such a drainage system, it is conceivable that the water collection tank may become full when a situation in which drainage is concentrated occurs. For example, in the case where the water is installed in a building such as an apartment, the drainage is concentrated at the commercial time of a popular event broadcast on TV, and the capacity of the pump cannot keep up with the water collection tank. It is possible that the water will be full.

In the past, by installing a water collection tank with a larger capacity or by installing a pressure pump with a higher capacity, the water collection tank was prevented from becoming full even if the above-mentioned drainage concentration situation occurred. .. Water collection tanks tend to be more expensive and require more installation space as their capacity increases. Pumping pumps also tend to be more expensive and require more installation space as their capacity increases.

Although the above-mentioned situation where drainage is concentrated is a rare situation, it is considered inefficient to install a large-capacity water collection tank and a high-performance pumping pump, which are expensive and require installation space. Be done. It should be noted that such a problem is not an inherent problem that occurs only in the vacuum type drainage system, but is a problem that occurs in a general drainage system including a water collecting tank and a pressure pump.

It is an open / close sensor that detects the open / close of the valve device provided between the sewage source and the water collecting portion.

Hereinafter, the drainage system and the server device according to the embodiment of the present invention will be described in detail with reference to the drawings.

<Drainage system>
FIG. 1 is a block diagram showing a main configuration of a drainage system according to an embodiment of the present invention. As shown in FIG. 1, the drainage system 1 of the present embodiment includes a sewage source 11, a water storage unit 12, a suction pipe 13, a valve device 14, a negative pressure drainage pipe 15, a water collection tank 16 (water collection unit), and a vacuum pump 17. , A vacuum pump 18, a valve opening / closing device 19, a flow sensor 20 (detection device), an edge server 21 (server device), and a terminal device 22.

It is assumed that the drainage system 1 of the present embodiment drains sewage generated in a building B such as a condominium or an apartment house to the outside (for example, a public drainage pipe). Therefore, among the above configurations forming the drainage system 1, the sewage source 11, the water storage unit 12, the suction pipe 13, the valve device 14, the negative pressure drainage pipe 15, and the flow rate sensor 20 are used for each room R of the building B (for example,). , It shall be provided for each exclusive part of the condominium).

The sewage source 11 is a place where sewage can be generated, for example, a sink in a toilet or a kitchen. The water storage unit 12 is installed in the vicinity of the sewage source 11, and is a portion for storing water supplied from the water supply, for example, a toilet tank or the like. The suction pipe 13 is a pipe for sucking sewage generated at the sewage source 11. One end of the suction pipe 13 is connected below the minimum water level of the water storage unit 12, and the other end is connected to the valve device 14.

The valve device 14 is a valve that is opened or closed based on an instruction from the valve opening / closing device 19. For example, when the sewage generated by the sewage source 11 is drained, the valve device 14 is opened based on the instruction from the valve opening / closing device 19, and the sewage generated by the sewage source 11 is discharged. When completed, the closed state is set based on the instruction from the valve opening / closing device 19. If no sewage is generated at the sewage source 11, the valve device 14 is closed.

The negative pressure drain pipe 15 is a pipe whose inside is kept in a negative pressure state by the vacuum pump 17, and one end is connected to the valve device 14 and the other end is connected to the water collection tank 16. As described above, since the valve device 14 is provided for each room R of the building B, one end of the negative pressure drain pipe 15 is connected to each of the valve devices 14 provided for each room R of the building B. Can be done. The water collection tank 16 is a tank for collecting sewage sucked by the negative pressure drain pipe 15.

The vacuum pump 17 is connected to the water collecting tank 16 via the negative pressure pipe P1 and is a pump for keeping the inside of the negative pressure drain pipe 15 in a negative pressure state via the water collecting tank 16. The vacuum pump 17 keeps the inside of the negative pressure drain pipe 15 in a negative pressure state, so that when the valve device 14 is opened, the pressure difference between the pressure in the negative pressure drain pipe 15 and the atmospheric pressure causes sewage. The sewage generated at the source 11 is collected in the water collection tank 16 via the suction pipe 13, the valve device 14, and the negative pressure drain pipe 15.

The pressure feeding pump 18 is a pump for pumping the sewage in the water collecting tank 16 to the outside. The pump 18 is connected to the network N and pumps the sewage in the water collection tank 16 to the outside under the control of the edge server 21. The connection form of the pump 18 to the network N may be arbitrary. For example, it may be a wired connection or a wireless connection. Further, it is desirable that the pump 18 is always connected to the network N.

The valve opening / closing device 19 is a device that gives an instruction to open or close the valve device 14. Examples of the valve opening / closing device 19 include a lever handle, a switch, a water level sensor and an arithmetic unit provided in the water storage unit 12, a timer, a water level sensor, an arithmetic unit, and the like. For example, the lever handle, switch, or water level sensor and arithmetic unit provided in the water storage unit 12 of the toilet can be used to give an instruction to open the valve device 14, and the timer or water level sensor and arithmetic unit can be used. , Can be used to give an instruction to close the valve device 14.

The flow rate sensor 20 is a sensor provided between the sewage source 11 and the water collection tank 16 to detect the flow rate of the sewage collected in the water collection tank 16. As described above, since the flow rate sensor 20 is provided for each room R of the building B, the flow rate sensor 20 generates water at the sewage source 11 for each room R of the building B and collects water in the water collection tank 16. It can be said that it is a sensor that detects the flow rate of sewage for each room R. The flow rate sensor 20 may be installed inside each room R or outside each room R.

The flow rate sensor 20 is connected to a network N such as the Internet, and transmits detection information indicating the detected flow rate of sewage to the network N toward the edge server 21. The connection form of the flow rate sensor 20 to the network N may be arbitrary. For example, it may be a wired connection or a wireless connection. Further, the flow rate sensor 30 does not necessarily have to be always connected to the network N, and may be connected to the network N only when the above detection information is transmitted to the network N.

The edge server 21 collects the detection information transmitted from each of the flow rate sensors 20 to the network N, performs a predetermined process, and controls the pump 18 based on the result of the process. Specifically, the edge server 21 performs statistical processing on the detection information of the flow rate sensor 20 collected via the network N to obtain a tendency of the water collection status of the water collection tank 16, and based on the tendency, the pumping pump 18 controls are performed.

For example, the edge server 21 performs statistical processing on the detection information of the flow rate sensor 20 to obtain information indicating the water collection status of the water collection tank 16 for each season, each day of the week, each time zone, and so on. Then, the edge server 21 controls the pressure feed pump 18 in consideration of the obtained information indicating the water collection status, so that the water collection tank 16 is not filled with water. For example, if the amount of water collected in the water collecting tank 16 tends to increase rapidly on Sunday night, the pressure pump 18 is operated from the afternoon of Sunday to the evening to reduce the amount of water collected in the water collecting tank 16 in advance. Take control. The timing of operating the pumping pump 18 is merely an example, and the pumping pump 18 may be operated at a time before a predetermined time from the time when the amount of water collected in the water collecting tank 16 is expected to increase rapidly. ..

Further, the edge server 21 performs a process of obtaining the optimum capacity of the water collecting tank 16 and the capacity of the pump 18 for the drainage system 1, and outputs information indicating the result of the process. Specifically, the edge server 21 changes the combination of the capacity of the water collecting tank 16 and the capacity of the pump 18 based on the information indicating the water collecting status of the water collecting tank 16 obtained by the above-mentioned statistical processing. A combination that does not fill the water collection tank 16 is obtained, and further, considering the cost and installation space for each combination, the optimum capacity of the water collection tank 16 and the capacity of the pump 18 are obtained for the drainage system 1.

The terminal device 22 is a terminal device connected to the network N and used to obtain various information from the edge server 21. The terminal device 22 is realized by, for example, a desktop type, a notebook type, or a tablet type personal computer. The terminal device 22 is operated by, for example, the designer of the drainage system 1, and is used to obtain the optimum capacity of the water collecting tank 16 and the capacity of the pump 18 for the drainage system 1 described above from the edge server 21.

<Server device>
FIG. 2 is a block diagram showing a main configuration of a server device according to an embodiment of the present invention. As shown in FIG. 2, the edge server 21 as the server device of the present embodiment includes a communication unit 31, a storage unit 32, a timekeeping unit 33, and a processing unit 34. The communication unit 31 is connected to the network N and performs communication via the network N under the control of the processing unit 34. The connection form of the communication unit 31 to the network N may be arbitrary. For example, it may be a wired connection or a wireless connection.

The storage unit 32 includes a primary storage device such as a volatile or non-volatile semiconductor memory, or a secondary storage device such as an HDD (hard disk drive) or SSD (solid state drive), and is used in the edge server 21. Memorize information. For example, information indicating the result of the above-mentioned statistical processing (seasonal, day of the week, time zone, and other information indicating the water collection status of the water collection tank 16) is stored. The timekeeping unit 33 has a timekeeping function such as a pulse counter, and measures the time.

The processing unit 34 includes a sensor data collecting unit 34a, a sensor data processing unit 34b, and a pump pump control unit 34c, and performs various processes and controls described above. The sensor data collection unit 34a collects the detection information transmitted from each of the flow rate sensors 20 to the network N. The sensor data processing unit 34b performs the above-mentioned statistical processing on the detection information collected by the sensor data collection unit 34a to obtain a tendency of the water collection status of the water collection tank 16. Further, the sensor data processing unit 34b also performs a process of obtaining the optimum capacity of the water collecting tank 16 and the capacity of the pump 18 in response to the request from the terminal device 22 via the network N, for example. .. The pumping pump control unit 34c controls the pumping pump 18 based on the result of the processing performed by the sensor data processing unit 34b.

<Operation of drainage system>
Next, the operation of the drainage system 1 in the above configuration will be described. First, it is assumed that the valve device 14 is closed in the room R where the building B is located. Further, it is assumed that the inside of the negative pressure drain pipe 15 is maintained in a negative pressure state by the vacuum pump 17. In this state, it is assumed that in the room R where the building B is located, the valve opening / closing device 19 gives an instruction to the valve device 14 to open the valve device 14.

Then, the valve device 14 is opened, and the sewage generated at the sewage source 11 due to the pressure difference between the pressure in the negative pressure drain pipe 15 and the atmospheric pressure is discharged from the suction pipe 13, the valve device 14, and the negative pressure drain pipe 15. Water is collected in the water collecting tank 16 via the water collecting tank 16. At this time, the flow rate of the sewage flowing through the negative pressure drain pipe 15 is detected by the flow rate sensor 20, and the detection information indicating the flow rate of the sewage is transmitted to the network N toward the edge server 21.

The detection information transmitted to the network N toward the edge server 21 is collected by the sensor data collection unit 34a of the processing unit 34 after being received by the communication unit 31 of the edge server 21. The detection information collected by the sensor data collection unit 34a is stored in the storage unit 32. The edge server 21 performs the above processing every time the detection information is transmitted from the flow rate sensor 20.

When the above processing is repeated and a certain amount or more of detection information is obtained, the detection information stored in the storage unit 32 is read out by the sensor data processing unit 34b, and the above-mentioned statistical processing is performed. The timing at which the statistical processing is performed by the sensor data processing unit 34b may be any timing, and may be performed, for example, every season, every day of the week, or every time zone. Information indicating the result of statistical processing performed by the sensor data processing unit 34b (seasonal, day of the week, time zone, and other information indicating the water collection status of the water collection tank 16) is stored in the storage unit 32. ..

When the above statistical processing is performed, the pumping pump control unit 34c controls the pumping pump 18 based on the processing result of the sensor data processing unit 34b. For example, when the time measured by the time measuring unit 33 becomes a time predetermined time before the time when the amount of water collected in the water collecting tank 16 is predicted to increase rapidly, the pumping pump control unit 34c performs the pumping pump. Control to operate 18. By performing such control, even if the drainage is concentrated, it is possible to prevent the water collecting tank 16 from becoming full.

Further, for example, when the terminal device 22 is operated by the designer of the drainage system 1 and a request for transmission of the optimum information of the drainage system 1 is made, the transmission request is transmitted to the edge server 21 via the network N. Then, the sensor data processing unit 34b of the edge server 21 performs a process of obtaining the optimum capacity of the water collecting tank 16 and the capacity of the pump 18 for the drainage system 1.

This processing result is transmitted from the edge server 21 to the terminal device 22 via the network N, and is displayed on the terminal device 22. By displaying such a display on the terminal device 22, for example, the designer of the drainage system 1 can refer to the determination as to whether or not the water collection tank 16 and the pressure feed pump 18 need to be replaced. Further, the designer of the drainage system 1 or the like can refer to the selection of the water collection tank 16 and the pump 18 used for the drainage system 1 to be introduced in a new building having the same degree as the building B, for example.

As described above, according to the present embodiment, the amount of sewage collected from the sewage source 11 to the water collection tank 16 is detected by the flow rate sensor 20, the detection information of the flow rate sensor 20 is transmitted to the network N, and the network. The edge server 21 collects and processes the detection information of the flow rate sensor 20 transmitted to N, and the edge server 21 controls the pump 18 based on the result of the processing. Therefore, efficient operation is possible.

Although the drainage system and the server device according to the embodiment of the present invention have been described in detail above, the present invention is not limited to the above-described embodiment and can be freely changed within the scope of the present invention. For example, in the above embodiment, a flow rate sensor 20 is provided for each room R of the building B to measure the flow rate of sewage (sewage generated at the sewage source 11 for each room R and collected in the water collection tank 16). Although the example of detecting for each R has been described, the amount of sewage may be detected by another method. For example, an open / close sensor for directly or indirectly detecting the opening / closing of the valve device 14 may be provided, and the amount of sewage may be detected from the detection result.

Further, in the above-described embodiment, the vacuum type drainage system 1 has been described as an example, but the present invention can be applied to a drainage system other than the vacuum type drainage system 1. Specifically, it can be generally applied to a drainage system including the same as the water collecting tank 16 and the pressure pump 18.
