Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to an online monitoring system for the operating status of a micro pump station based on the Internet of Things. Background Art

[0002] With the acceleration of urbanization, the demand for sewage treatment is rapidly increasing. As critical infrastructure, the operating status of pump stations is directly related to sewage treatment efficiency and environmental safety. Currently, common real-time monitoring technologies for sewage pump operating status typically rely on the collection and analysis of relevant pump operating parameters. These parameters are acquired by installing various sensors on the pumps and then transmitted to the terminal for processing and analysis.

[0003] However, due to differences in structure and function between different types of water pumps, each type of water pump needs to be equipped with a specific type of sensor. Each additional water pump requires specialized development and debugging of the monitoring system, resulting in poor adaptability and replicability. Existing monitoring technologies often focus on the operation of the water pump itself, while ignoring the overall operation of the pump well. For example, important factors such as water level changes in the pump well are not effectively monitored and analyzed. This localized monitoring perspective cannot fully reflect the operating status of the pump station, which may cause some potential problems to be overlooked, thereby affecting the normal operation of the pump station and the sewage treatment effect. Summary of the Invention

[0004] In response to the above problems, this application provides an online monitoring system for the operating status of a micro pump station based on the Internet of Things. It uses water pump operating auxiliary parameters, water level changes at key points in the pump pool, etc. as factors, and collects, uploads, and analyzes them through the industrial Internet of Things system to obtain the overall operating status of the pump well.

Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features indicated. Thus, features specified as "first" or "second" may explicitly or implicitly include one or more of such features; and in the description of this application, unless otherwise specified, "plurality" means two or more.

[0028] Example 1

[0029] See Figure 1 , Figure 1 This is a flow chart of an online monitoring system for the operation status of a micro pump station based on the Internet of Things. The embodiment of the present application provides an online monitoring system for the operation status of a micro pump station based on the Internet of Things, comprising: a water pump, a signal collection module, a data upload module, a pump well operation monitoring platform, and a terminal device.

[0030] The signal collection module includes a pressure sensor, a water level sensor, and a current sensor, which are used to monitor and collect auxiliary parameters of the water pump operation in real time;

[0031] The pressure sensor is arranged on the water outlet pipe of the water pump to monitor the change of water pressure in the water outlet pipe and judge whether the water pump is started or stopped and whether the water outlet is supported.

[0032] Specifically, after the sewage flows through the water pump, the pressure when it passes through the water outlet pipe of the water pump can reflect the output capacity of the water pump and the system resistance, and can represent the pressure condition at the output end of the water pump; the head of different water pumps is usually within more than 20 meters, and the pressure that needs to be monitored is not large. Therefore, setting the pressure sensor here can adapt to different water pump and system configurations without the need to customize it for each specific model.

[0033] Furthermore, the pump well monitoring platform has preset alarm thresholds, and the pressure sensor monitors changes in the outlet pipe water pressure in real time. If the water pressure falls below the lower limit set by the monitoring platform, the pump may not be fully operating or the pipe may be leaking. If the water pressure rises abnormally, it may be due to a blockage in the downstream pipe or an improperly closed valve. Abnormally high pressure at the outlet may also cause jacking. Based on the real-time monitoring results, personnel need to take measures, such as shutting down the pump, increasing the pump's output power, or identifying and clearing the blockage, to ensure the normal operation and efficiency of the pump station.

[0034] In a possible implementation, the water level sensor is disposed below the overflow port to monitor water level changes and control the start and stop of the water pump accordingly.

[0035] Specifically, when the water level sensor detects that the water level has reached the pre-set starting water level of the pump well monitoring platform (usually slightly lower than the overflow port to ensure that there is enough water for the pump to pump), the water level sensor sends a signal, and the personnel starts the water pump to begin pumping operations; as the water pump runs, the water level gradually drops. When the water level drops to another pre-set stop water level (lower than the starting water level to avoid frequent starts and stops), the water level sensor will send a signal again, and the personnel will stop the water pump to avoid the pump running dry or wasting energy. By monitoring the water level and starting the water pump when the water level is close to the overflow port, water overflow can be effectively prevented, avoiding water damage and possible structural damage; stopping the water pump when the water level is too low can prevent the water pump from running in a waterless state, avoid overheating or damage to the water pump, and also prevent the waste of water resources.

[0036] Optionally, the water level sensor is a float-type water level sensor, which detects and measures the water level by utilizing the principle that a float rises and falls with changes in the liquid level. When the water level rises, the float rises accordingly; when the water level falls, the float falls accordingly. The float transmits its position change through a mechanical or magnetic connection, which in turn triggers a switch or sensor, generating an electrical signal to indicate the water level.

[0037] In a possible implementation, the current sensor is electrically connected to the water pump motor and is used to detect the water pump wiring current.

[0038] Specifically, the current sensor can determine the operating status of the water pump and whether there is electricity theft. Under normal operating conditions, the current level should be stable within a certain range. If the current is abnormal, such as a sudden increase or fluctuation, this indicates that the water pump is overloaded, blocked, bearing worn, or has an electrical fault, allowing maintenance personnel to respond quickly. When an additional load is connected to the power grid without authorization, the current sensor will detect an abnormal increase or pattern change in current. By setting an alarm threshold on the pump well monitoring platform, when an abnormal current is detected, an alarm is triggered, thereby alerting management personnel to the possible existence of electricity theft so that necessary legal or safety measures can be taken.

[0039] Optionally, the water pump motor is a three-phase asynchronous motor, and the current sensor is responsible for the three-phase current testing and protection. Phase loss causes the remaining phase current to be too high, causing the motor to overheat and damage; phase sequence error causes the motor to reverse or run unstably. The current sensor continuously detects the three-phase current. Once an error is found, the protection mechanism is triggered, cutting off the power supply or issuing an alarm to prevent motor damage or system failure.

[0040] In a possible implementation manner, the data uploading module is used to receive the real-time auxiliary parameters of the water pump operation collected by the signal collecting module and send them to a designated server;

[0041] The server is used to receive and process the water pump operation auxiliary parameters sent by the data upload module and forward them to the pump well operation monitoring platform;

[0042] Specifically, the server will perform preliminary processing on the data, including data cleaning, data conversion, and data storage.

[0043] Optionally, the server is a cloud server or a local server.

[0044] In a possible implementation, the pump well operation monitoring platform is used to receive and display the water pump operation auxiliary parameters in real time;

[0045] In a possible implementation manner, the terminal device is communicatively connected to the pump well operation monitoring platform, and is configured to receive the water pump operation auxiliary parameters and pump station operation status sent by the pump well operation monitoring platform.

[0046] In a possible implementation, the signal collection module further includes: a water immersion detector and a mains power failure alarm.

[0047] The water immersion detector is used to send out an alarm signal when the water level exceeds the warning level and is about to overflow.

[0048] Specifically, if the water level rises rapidly due to excessive rainfall, pipe rupture or other reasons, the flood detector can detect this change in time and send an alarm signal before the water level reaches a level that may cause overflow.

[0049] Wherein, the mains power failure alarm is used to send out an alarm signal when a mains power failure occurs.

[0050] Specifically, the mains power outage alarm monitors the status of the power line in real time. Once a mains power outage is detected, an alarm signal is immediately issued and the backup power supply is switched to keep the basic functions of the pump station running continuously.

[0051] Optionally, the power failure alarm is usually powered by a battery to ensure that it can still work normally when the main power fails.

[0052] In one possible embodiment, the pump well operation monitoring platform further includes a data analysis module for automatically identifying and locating the source of the fault in the pump station and issuing an alarm signal based on the real-time collected auxiliary parameters of the water pump operation combined with a preset fault diagnosis rule library.

[0053] In a possible implementation, the fault diagnosis rule base includes a first diagnostic unit for analyzing the operating status of the water pump, including at least one of the following conditions: water pump failure, severe water pump blockage, abnormal water pump current, and frequent start and stop of the water pump. Specifically,

[0054] (1) Water pump failure: the judgment is based on the fact that both the high and low float switches indicate water level signals, and the operating current of the water pump and the water pressure of the outlet pipe are at the lowest value.

[0055] (2) The water pump is seriously clogged. The basis for judgment is that the operating current of the water pump is abnormally large and the water pressure of the outlet pipe is abnormally low.

[0056] (3) The water pump current is abnormal. The basis for judgment is that the difference in the three-phase current of the same water pump exceeds 10% of the normal value range.

[0057] (4) The water pump starts and stops frequently. The judgment is based on 6 or more repeated starts and stops within an hour (for some pump pits, the size of the pool and the changes in water inflow must also be considered).

[0058] In a possible implementation, the fault diagnosis rule base further includes a second diagnosis unit for analyzing the operating state of the water level, including at least one of the following situations: top support, overflow, specifically,

[0059] (1) Jacking: The basis for judgment is that the current of the water pump is normal and the water pressure of the outlet pipe is abnormally high.

[0060] (2) Overflow alarm: the judgment is based on the signal sent by the water detector.

[0061] Specifically, after receiving the water pump operation auxiliary parameters from the server, the data analysis module forwards the parameters collected by the pressure sensor and the current sensor to the first diagnostic unit, and forwards the parameters collected by the water level sensor to the second diagnostic unit.

[0062] In a possible implementation, the pump well operation monitoring platform further includes an alarm module for performing monitoring and alarming according to the alarm signal sent by the data analysis module.

[0063] Optionally, the pump well operation monitoring platform presets alarm thresholds for various parameters such as pressure, current, water level, etc., which are used to monitor the operation status of the water pump in real time, and trigger an alarm when the monitored auxiliary parameters of the water pump operation exceed the normal range, thereby ensuring the safety and stability of the pump station operation.

[0064] In a possible implementation, the pump well operation monitoring platform further includes a display module for displaying in real time the water pump operation auxiliary parameters and alarm notifications received from the data analysis module and the alarm module.

[0065] Specifically, the display module is the main interface for users to interact with the monitoring platform, and is used to display the auxiliary parameters, operating status information, and alarm notifications of the pump station in real time.

[0066] Optionally, the display module presents the water pump operation auxiliary parameters and alarm notifications in a graphical manner, such as a dashboard, a trend chart, an alarm list, etc.

[0067] In a possible implementation, the terminal device is communicatively connected to the pump well operation monitoring platform, and a user can remotely view the operation status of the pump station and receive alarm information.

[0068] In a possible implementation, the terminal device is a smart phone, a tablet, or a personal computer.

[0069] Specifically, users can log in through a dedicated application or web interface to view the various operating parameters of the pump station in real time; when the operating parameters of the pump station exceed the preset normal range or a potential fault is detected, the pump well operation monitoring platform will automatically trigger an alarm and send the alarm information to the terminal device via push notification, SMS, email or phone call, ensuring that users can immediately know the abnormal condition of the pump station and take timely countermeasures to avoid or reduce possible damage.

[0070] In a possible implementation, the data upload module is an industrial Internet of Things gateway, including one or more combinations of a short-range communication device, an NB-IoT module, a LoRa module, a 4G module, or a 5G module.

[0071] In a possible implementation, data transmission between the data upload module and the pump well operation monitoring platform adopts an encrypted communication protocol, and the platform has data access log recording and auditing functions.

[0072] The beneficial effects of the embodiments of the present application are as follows:

[0073] The online monitoring system for the operation status of a micro pump station based on the Internet of Things described in this application mainly collects the outlet pipe pressure of the water pump at the main outlet pipe sensor. It can adapt to all water pump models and does not require special customization. The on-site installed set of equipment has low cost and can be replicated in large quantities. The system integrates a series of high-performance sensors, including pressure sensors, water level sensors, current sensors, etc., which can monitor the operation status of the pump station in an all-round and multi-dimensional manner. It is not limited to the monitoring of a single parameter, but forms a monitoring network covering the main operating indicators of the pump station, ensuring an accurate grasp of the overall health status of the pump station. With the help of Internet of Things technology, the system supports remote monitoring, and the terminal equipment can obtain the operation status of the pump station in real time and receive alarm information, making the operation and maintenance of the pump station more efficient and convenient.
