[0002] As an important part of the urban water supply system, the operating efficiency, safety and stability of the raw water pump station are directly related to the quality of residents' lives and urban development. In the traditional water supply system, there are many problems such as outdated water supply construction mode, aging facilities, unstable system operation, and high raw water supply risks. Especially in the operation and management of raw water pump stations, there has long been a situation of low management efficiency and high labor costs. To this end, it is necessary to update the basic automatic control equipment, build the information of the pump station, and establish a water supply information monitoring and early warning system to promote the intelligent construction of the water supply system.

[0003] In the operation of traditional pumping stations for water supply, the water pump valves do not have the function of remotely monitoring basic water supply information, and the raw water pumping stations lack dynamic monitoring of equipment operation. This results in low overall operating efficiency of the pumping stations and inability to detect abnormal water supply conditions in a timely manner and issue early warnings. Summary of the invention

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0043] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present invention.

[0044] Embodiment 1:

[0045] In the process of water supply system construction, the demand for more stable, efficient and safer water supply has given rise to the concept of smart water affairs. As an extremely important part of urban construction, smart water affairs has played a positive role in promoting innovation and development in the field of "intelligence". The purpose of smart water affairs is to analyze and utilize water resource data, improve the operation and management level of water enterprises, and then use some intelligent algorithms to predict some long-term needs or potential problems in the water industry, and reasonably allocate and dispatch resources. At present, there is still a long way to go for the intelligence of water supply in my country, and the field of smart water affairs is still in the exploratory stage. Most smart water affairs construction still stays at the platform layer and application layer, lacking a full-process solution from underlying data collection to intelligent analysis and then to decision-making system optimization.

[0046] In the intelligent construction of the entire water supply system, the intelligent construction of pump stations plays a vital role. As an important part of the water resources management system, the intelligent pump station can realize automatic and intelligent monitoring and control, and improve the utilization efficiency, management level and energy utilization rate of water resources. The intelligent information management system of the pump station is to establish environmental information perception, multi-information analysis, data deep mining and intelligent decision-making system in water supply scheduling, and finally form a comprehensive supervision platform for intelligent water supply system with complete environmental elements, advanced analysis models, complete basic data, interconnected application systems, and information sharing and utilization, which will produce technological innovation and provide technical support for the intelligent application of business management.

[0047] At present, most pumping stations still use the traditional water supply mode, mainly relying on industrial frequency or variable frequency water pumps to extract and transport water to meet different water needs. Traditional pumping stations are mainly composed of water pump units, inlet and outlet pools, electrical equipment, control systems and necessary auxiliary facilities. The water pump unit is responsible for lifting water to the required height or pressure and driving the water pump through the motor. The control system is responsible for monitoring the operating status of the pump station, adjusting the operating parameters of the water pump, and ensuring the safe, stable and efficient operation of the water supply system. In the water supply operation of traditional pumping stations, the water pump valves do not have the function of remotely monitoring the basic information of water supply, lack of dynamic monitoring of equipment operation, and equipment operation records, water level monitoring and other operation records are all in paper form, requiring more human resources, relatively low degree of automation, and lack of monitoring systems. This leads to low overall operating efficiency of the pumping station, poor water supply safety and stability, and inability to flexibly adjust the water supply according to actual needs, resulting in waste of water resources. At the same time, more manual intervention and operation are required, which increases operating costs and management difficulties.

[0048] This embodiment provides a raw water pump station information monitoring and early warning method, which aims to achieve comprehensive and real-time monitoring of the operating status of the raw water pump station by integrating multiple sensors, data analysis and processing technologies, and to provide early warnings for potential problems, thereby ensuring the safe and stable operation of the water supply system. The method is implemented through a water supply information monitoring module, a water supply information transmission network, an integrated server, and a remote operation and maintenance control and management platform. Specifically:

[0049] The water supply information monitoring module includes a variety of different types of high-precision sensors, which are installed in the pump station. They automatically monitor and record basic water supply information such as water volume, pressure, valve opening, liquid level, temperature, water quality, etc. during the operation of the water supply pump station. Then, the water supply information monitoring module transmits the monitored water supply information to the integrated server through the water supply information transmission network. The integrated server processes, classifies, and counts the received water supply information. According to the preset thresholds and monitoring data, it automatically determines whether there are any abnormal conditions, and sends out early warnings or alarm signals through the remote operation and maintenance control and management platform. It should be noted here that the integrated server The server supports multiple alarm modes, such as sound and light alarms, SMS notifications, email reminders, etc., to ensure that managers can respond in time; the remote operation and maintenance control and management platform is based on the combination of data information of the integrated server and the remote monitoring interface of the Web or mobile terminal. Operation and maintenance personnel and managers can view the basic information of water inlet and outlet of the pump station, the operation status of the pump unit, and the security monitoring status anytime and anywhere, realize remote operation and maintenance control, online record, query inspection, operation and maintenance, and other management situations. At the same time, it also supports daily operation reports, water volume statistics, energy consumption analysis, pressure statistics and other data query and report generation functions to provide support for decision-making.

[0050] During the actual operation of the raw water pump station, various types of monitoring data will fluctuate to a certain extent due to the influence of environmental factors. When a certain monitoring data exceeds a preset threshold at a certain moment or a short period of time, the remote operation and maintenance control and management platform will display a warning or alarm signal at this moment or period. In fact, such a short-term fluctuation does not require the management personnel to do any processing work. Such warning or alarm signals undoubtedly increase the workload of the management personnel and also bring pressure on the system data storage. Therefore, the present invention further proposes a new solution for judging whether the monitoring data really meets the warning standard. The specific contents are as follows:

[0051] When the integrated server collects the water supply information at the current moment, it also retains the historical water supply information collected before. When the water supply information I0 at a certain moment t0 exceeds the preset threshold, it sends a warning to be confirmed signal to the management personnel through the remote operation and maintenance control and management platform or other means. At the same time, it detects whether the management personnel confirms the warning to be confirmed signal. If the management personnel does not confirm the warning to be confirmed signal, the integrated server extracts the historical water supply information I0 at the i moments before t0. i Calculate the data fluctuation value B0 and use B0 as the standard value for the next fluctuation assessment. Data fluctuations below this standard value are ignored. If the manager confirms the warning signal to be confirmed, the data fluctuation value B0 will not be recorded. The calculation formula for the data fluctuation value is:

[0052]

[0053] Where: I0 is the water supply information at a certain moment, I i is the historical water supply information at the i-th moment, B0 is the data fluctuation value at the moment t0, and S is the fluctuation coefficient, which is pre-set by the management personnel.

[0054] When the water supply information I1 at time t1 exceeds the preset threshold, the integrated server calculates the data fluctuation value B1 at this time according to the above steps. If B1 is less than B0, the duration of this data fluctuation is recorded. If the duration of the data fluctuation is greater than the preset value, an early warning signal is issued to the management personnel, otherwise the data fluctuation is ignored; if B1 is greater than B0, an early warning signal to be confirmed is issued to the management personnel through the remote operation and maintenance control and management platform or other means. At the same time, it is detected whether the management personnel give feedback to the early warning signal to be confirmed. If the management personnel do not give feedback instructions to the early warning signal to be confirmed, B1 is retained and B0 is discarded. If the management personnel give feedback instructions to the early warning signal to be confirmed, B0 is retained and B1 is discarded, and so on. Through the above method, the early warning caused by some data fluctuations can be effectively avoided, thereby reducing the workload of the management personnel and also reducing the data storage pressure of the system.
