Description

Technical Field

[0001] This utility model relates to the field of drainage monitoring system technology, and in particular to a real-time drainage monitoring system based on the Internet of Things. Background Technology

[0002] The existing integrated pumping station operates as follows: water from the city's drainage pipes enters the cylinder through the inlet pipe and first comes into contact with a shredder. The shredder cleans up larger impurities in the water, breaking them down into smaller fragments. These fragments are then pumped out by the lift pump and discharged through the outlet pipe, thus transporting sewage or rainwater from the city's drainage system. The existing integrated pumping station is also equipped with a level sensor to monitor the water level inside the station. When the level sensor detects that the water level inside the station has reached a set threshold, the controller activates the lift pump to achieve automated drainage. This intelligent and automatic drainage greatly improves efficiency and is more convenient than traditional manual control. However, when existing integrated pumping stations malfunction, they often require manual repair, and the repair time is uncertain, often depending on the worker's experience and ability. To facilitate real-time identification of fault points within the integrated pumping station, a real-time drainage monitoring system based on the Internet of Things (IoT) needs to be designed to address these issues. Utility Model Content

[0003] This invention provides a real-time drainage monitoring system based on the Internet of Things. The system processes the signals from various sensors in real time through a controller to identify the fault point when a fault occurs in the drainage process, thereby facilitating maintenance personnel to quickly know the location of the fault point.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

The system further includes a level sensor placed inside a cylinder to monitor the water level inside the cylinder, a speed sensor installed on multiple lift pumps inside the cylinder to monitor the rotor speed of the lift pumps, and at least one flow sensor installed on branch water pipes at the output ends of the multiple lift pumps. The output ends of the level sensor, speed sensor, and flow sensor are all connected to the input end of the controller. The controller monitors the drainage process in real time based on the signals from each sensor, and the external terminal determines the location of faults in the drainage process by receiving data sent by the controller.

[0006] Preferably, each branch water pipe has two flow sensors, including a branch pipe input flow sensor installed at the input end of the branch water pipe and a branch pipe output flow sensor installed at the output end of the branch water pipe.

[0009] Preferably, the controller also has a feedback module, which determines the location information of the fault point based on the signals fed back by each sensor.

[0010] Preferably, the controller's communication module is connected to an external terminal via a wireless network.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] To enable those skilled in the art to understand the innovative aspects of this utility model, the prior art of the integrated pump station involved in this utility model will first be described, with reference to... Figure 1 and Figure 2The existing integrated pumping station, viewed from the outside, includes a cylindrical body 1 with an inlet pipe 2 and a main outlet pipe 3, and a controller 4 (implemented via an internal communication module 401) that can communicate with an external terminal 13. The inlet pipe 2 extends from the outside of the cylindrical body 1 to the inside of the cylindrical body 1 and connects to a pulverizing grid 5 inside the cylindrical body 1. The pulverizing grid 5 is used to pulverize impurities in the water coming from the inlet pipe 2, causing the impurities to form small particles. Inside the cylindrical body 1, there are multiple lift pumps 6, usually three, and the output end of each lift pump 6 is connected to a branch water pipe 7. The ends of multiple branch water pipes 7 are connected to a main outlet pipe 3. A liquid level sensor 8 is also installed inside the cylinder 1 to monitor the liquid level inside the cylinder 1. During operation, when the liquid level sensor 8 inside the cylinder 1 detects that the water level inside the cylinder 1 has reached the set value, the liquid level sensor 8 transmits the signal to the controller 4. The controller 4 controls the lifting water pump 6 to work and drain the water inside the cylinder 1. During the drainage process, the water inside the cylinder 1 is discharged to the outside of the cylinder 1 through the lifting water pump 6, branch water pipes 7 and main outlet pipe 3. The above is a description of the prior art involved in this utility model.

[0024] During long-term operation, existing automated pumping stations inevitably experience some parts malfunctioning, leading to low operating efficiency or even complete failure. Furthermore, internal maintenance after a malfunction is a complex task. To address this issue, this invention proposes a real-time drainage monitoring system based on the Internet of Things (IoT) for use in integrated pumping stations. This system aims to promptly assist staff in identifying the location of the fault when a malfunction occurs within the integrated pumping station.

[0025] For details, please refer to Figure 3 and Figure 4The main innovation of this utility model lies in the monitoring of the drainage process of the integrated water pump by installing sensors inside the integrated pump station. Specifically, in addition to the liquid level sensor 8 already in the prior art, the installed sensors also include a speed sensor 9 installed on the lift pump 6 to monitor the rotation speed of the rotor end of the lift pump 6. The signal from the speed sensor 9 can determine whether the lift pump 6 is working normally. There is also a flow sensor installed at the output end of the lift pump 6 (on the branch water pipe 7). The flow sensor can determine whether there is water flow at the output end of the lift pump 6. The output ends of the liquid level sensor 8, speed sensor 9 and flow sensor are all connected to the input end of the controller 4. After receiving the signals from each sensor, the controller 4 transmits the signals to the external terminal 13. The external terminal 13 can determine whether there is a fault and the location of the fault point based on the signals from each sensor. Alternatively, a feedback module 402 can be set inside the controller 4 to determine whether there is a fault and to determine the location of the fault point after a fault occurs, so as to realize the location determination of the fault point and then send the fault point location signal to the external terminal 13 for direct viewing.

[0026] Specifically, in determining the location of a fault, firstly, when the signal from the level sensor 8 is abnormal, such as no signal being transmitted to the controller 4, the controller 4 can determine that the level sensor 8 is faulty. When the speed sensor 9 does not detect a speed signal, the controller 4 assumes that the booster pump 6 is damaged. When the flow sensor does not detect a flow signal, the controller 4 determines that the output end of the booster pump 6 is damaged. These are all direct ways to determine the location of the fault. However, since the integrated pump station is used to treat sewage all year round, its working environment is relatively harsh, and there are many reasons why parts cannot maintain normal operation. There are many indirect ways to determine the location of the fault.

[0027] For example, when the level sensor 8 is damaged (e.g., its sensitivity drifts), it will continuously output a signal, indicating the presence of water inside the cylinder 1, even though there is actually no water in the cylinder 1. In this case, the controller 4 will continuously control the lifting pump 6 to operate, which is a common fault. However, this invention uses the speed sensor 9, flow sensor, and level sensor 8 in conjunction to monitor the system, making it easy to determine that the fault is caused by the level sensor 8. That is, when the level sensor 8 detects the presence of water inside the cylinder 1, the controller 4 controls the lifting pump 6 to operate. At this time, each speed sensor 9 will monitor... Once the booster pump 6 has started working, each flow sensor should be able to detect water flow through the branch pipe 7. If the level sensor 8 does not detect water flow through the branch pipe 7, it can be determined that the level sensor 8 inside the cylinder 1 is faulty. The cause of the fault may be excessive sensitivity drift, so that personnel can directly repair and replace the level sensor 8. This is an indirect way to determine if the level sensor 8 is damaged. Of course, the cause of the fault may also be a damage to the flow sensor, but there are many flow sensors and the probability of damage is low, so the level sensor 8 is more likely to be the cause.

[0028] Furthermore, since each booster pump 6 has a branch water pipe 7 at its output end, fault monitoring of the branch water pipe 7 is also essential. To determine whether there is a fault (such as a leak) in the branch water pipe 7, this can be achieved through the following methods: Figure 6 As shown, there are two flow sensors, including a branch pipe input flow sensor 10 installed at the input end of the branch pipe 7 and a branch pipe output flow sensor 11 installed at the output end of the branch pipe 7. By installing flow sensors at both the input and output ends of each branch pipe 7, the branch pipe 7 can be monitored to determine whether there is a leak. That is, when the flow sensor value at the branch pipe input end is less than that at the branch pipe output end, it is theoretically determined that there is a leak in the branch pipe 7. This allows maintenance personnel to quickly identify which branch pipe 7 has a leak or whether the flow sensor on the corresponding branch pipe 7 is damaged.

[0029] Furthermore, fault point monitoring of branch water pipe 7 can also be achieved through the following methods, such as... Figure 7 As shown, the flow sensor on branch water pipe 7 ( Figure 7The quantity (not marked in the text) is one. The above-mentioned flow sensor also includes a main outlet pipe flow sensor 12. The main outlet pipe flow sensor 12 is installed on the main outlet pipe 3, which is connected to the ends of multiple branch pipes 7. When the sum of the flow values ​​monitored by the flow sensors on the branch pipes is less than the flow value monitored by the flow sensors on the main outlet pipe 3, it can be determined that there is a leak in the branch pipe 7 or that a flow sensor at a certain point is damaged. This method of monitoring can also detect leaks in the branch pipes 7, but it cannot determine which specific branch pipe has a leak.

[0030] Furthermore, the monitoring of branch water pipes can also be achieved by combining the two monitoring methods mentioned above. That is, each branch water pipe 7 has two flow sensors. The two flow sensors include a branch pipe input flow sensor 10 installed at the input end of the branch water pipe 7 and a branch pipe output flow sensor 11 installed at the output end of the branch water pipe 7. The flow sensors also include a main outlet flow sensor 12, which is installed on the main outlet pipe 3 that is connected to the ends of multiple branch water pipes 7. By making comprehensive judgments, false alarms can be prevented.

[0031] It should be further explained that the external terminal 13 should be able to connect to the controllers 4 of multiple drainage monitoring systems, so that one external terminal 13 can simultaneously observe and monitor the operating parameters of multiple integrated pumping stations. The external terminal 13 preferably communicates with the controller 4 via a wireless network. It should also be explained that when the controller determines the location of the fault point based on the data from each sensor, it can send a fault code (usually one fault code represents one or more fault conditions) to the external terminal, so that maintenance personnel can quickly locate the fault point.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above-described embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
