Description

Technical Field

[0001] The present invention belongs to the field of electronic information, and relates to the field of integration of video monitoring and industrial control configuration, and in particular to an intelligent inspection method for pump stations that links an industrial control configuration process interface with video monitoring. Background Art

[0002] With the continuous advancement of urban construction in my country, water pumps are often installed and maintained in municipal water conservancy projects. It is these water pumps that work day and night to ensure the normal water and drainage needs of urban residents in their daily lives, and also to ensure the normal operation of the urban water supply system. Therefore, the maintenance and daily operation management of pump stations are related to the improvement of people's living standards and the progress of the national economy. With the construction of cities, the number of pump stations is increasing. The traditional maintenance method of pump stations has management problems such as low technical ability of operation and maintenance personnel, untimely maintenance, and tight personnel, which leads to information asymmetry, difficulty in management, high energy waste, and high operation and maintenance costs. To solve these pain points, it is necessary to optimize the operation and maintenance of pump stations, realize intelligent control to start the power supply, reduce equipment no-load operation, reduce maintenance waiting time, strengthen management cost control, and improve the overall dispatching level, so as to ensure efficient, reliable, energy-saving and safe operation of pump stations. To achieve this goal, we must first realize the unattended operation of pump stations. How to ensure the water supply safety of pump stations in unattended mode? Then it is necessary to have the intelligent inspection function of pump stations.

[0003] There are two main systems at the pump station site, one is the process automation control system, and the other is the video surveillance system. The video surveillance system is not only an important part of the security system, but also an essential facility for intelligent inspection. Video surveillance is widely used in many occasions because of its intuitiveness, accuracy, timeliness and rich information content. Although the traditional industrial site is equipped with a video surveillance system, the video surveillance system and the industrial control configuration system are independent of each other. When the two are used together, the operation is cumbersome and time-consuming. Summary of the invention

[0004] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a pump station intelligent inspection method based on image recognition and process video linkage, which is used to solve the problems of difficult pump station management and low energy utilization. Intelligent inspection of pump stations is to organically combine the Internet of Things with automation equipment, and use software and hardware technologies such as intelligent equipment, intelligent sensors, communication technology, video monitoring, and automatic control to monitor the existing equipment of the pump station through video monitoring and automatic control management, so as to grasp all kinds of information and data of the pump station in real time; it can effectively solve the problems existing in the current pump station management, and realize 24-hour real-time monitoring of online data such as pressure and flow in the area where the pump station is located through monitoring cameras, intelligent sensors and other equipment, and realize the operation status of the power equipment of the pump station remotely monitored in the pump station monitoring center, support manual control, automatic control, and remote control of the start and stop of the pump group of the pump starting equipment, and greatly simplify the control and management of the pump station.

[0005] The technical solution is as follows:

[0006] A pump station intelligent inspection method based on image recognition and process video linkage includes the following steps:

[0007] (1) Set up the linkage between pump station process equipment and video: Integrate the video monitoring system with the industrial control pump station system. The pump station process interface displays the process and operation data of the corresponding site, and displays the video monitoring interface of the corresponding site at the same time; and bind the process equipment in the pump station process interface with the preset points of the corresponding video monitoring camera. When clicking on the process equipment in the site pump station process interface, a command is sent to the camera pan / tilt. After receiving the command, the camera pan / tilt adjusts the lens to the corresponding set position;

[0008] (2) Formulate an inspection process list: According to the pump station process and relevant regulations on pump station inspection management, set the inspection points and inspection sequence, generate an inspection process list, and set the automatic inspection time or manual inspection cycle;

[0009] (3) Perform remote manual inspection: Click the "Start Inspection" button on the pump station process interface. The video screen will automatically switch to the first inspection point according to the inspection list. The administrator will view the actual situation of the point through video monitoring, fill in the confirmation result, and the background will automatically capture the image of the point and upload it to the server. Click the "Continue Inspection" button, and the video screen will automatically switch to the next inspection point according to the inspection list until all points are inspected.

[0010] (4) Perform remote automatic inspections: Set the automatic inspection cycle, and the background will automatically perform inspection tasks according to the inspection list, take several pictures of each inspection point, and upload them to the server. The server uses image recognition methods (Baidu AI Open Platform image recognition technology and text recognition technology) to identify the digital information on the dials in the pictures (such as water meters, electricity meters, gas meters, pressure gauges, flow meters, etc.), and compares it with the operating data collected and reported by the system to generate the comparison results of the automatic inspection. If the difference between the two is large, the alarm process is automatically triggered and an exception handling application form is generated. If the management personnel review and need to handle it on site, an on-site maintenance task order is generated and inspection personnel are dispatched to the site for processing.

[0011] Furthermore, in step (2), when the manual inspection period has expired and no inspection has been performed, the system automatically generates an inspection reminder message.

[0012] Furthermore, in step (3), if an abnormal situation is encountered during the inspection, an abnormality handling application form is submitted, an on-site maintenance task form is generated, and inspection personnel are dispatched to the site to handle it.

[0013] Furthermore, the process and operation data include: pressure, flow, frequency, current, voltage, and liquid level.

[0014] Furthermore, the specific steps of step (2) are as follows:

[0015] S1. According to the relevant regulations on inspection management, the management shall reasonably determine the details of the inspection and enter the inspection assessment items into the system as the basic data for the inspection;

[0016] S2. Develop inspection plan: divide inspection groups according to the geographical location of pump stations, set automatic inspection and manual inspection cycles, set inspection team members for each group, and assign personnel permissions;

[0017] S3. Generate inspection tasks on a monthly basis: At the end of each month, the system automatically generates the inspection plan for the next month based on the inspection tasks of the previous month. Temporary personnel adjustments must be completed before the 1st of the next month.

[0018] The beneficial effects of the present invention are:

[0019] The intelligent inspection method for pump stations based on image recognition and process video linkage described in the present invention is based on the integration of video monitoring system and industrial control configuration system, and is designed to implement an intelligent inspection method that combines remote video manual inspection and automatic inspection in unmanned pump station scenarios; the method is convenient, intuitive and reliable, and perfectly combines video monitoring with industrial control configuration. The intelligent inspection method can not only efficiently monitor the operating status of the pump station and promptly discover safety hazards such as equipment failures, but also greatly reduce the investment in human resources, helping governments and enterprises to effectively save costs while ensuring equipment safety, thereby creating greater economic benefits.

[0020] The intelligent inspection method can also achieve the following effects:

[0021] ① Improve the process safety of pump stations and take precautions first; monitor equipment failures in real time, discover potential failures in a timely manner, and shorten the time for judging and handling failures.

[0022] ② Energy saving and consumption reduction: Reduce water leakage rate by 60%, intelligently start and stop water pumps according to the liquid level of the reservoir, extend the service life of water pumps, and reduce power consumption;

[0023] ② Reduce labor costs: Use intelligent inspections instead of manual labor, reduce manpower input by about 80%, and reduce personnel inspection and equipment maintenance costs.

[0024] ④ Ensure stable water supply: Intelligently control the main and standby water pumps. Once a water pump fails, the vacant work can be promptly scheduled to ensure the safe, stable and long-term operation of the water supply system.

[0025] ⑤Optimize decision-making management: optimize the office convenience, refined management, and intelligent command and decision-making of water supply enterprises, and comprehensively improve enterprise management efficiency and service level. BRIEF DESCRIPTION OF THE DRAWINGS
