One article to understand “autonomous inspection”
Is "autonomous inspection" feasible?
This is a common confusion among many petrochemical companies.
Today, an article explains "autonomous inspection" to build thinking on understanding.
1. How to realize autonomous inspection?
First of all, we need to know the meaning of "autonomous inspection".
In a general sense, autonomous inspection refers to the comprehensive use of electronic technology, computer technology, communication technology and control technology to replace humans in data collection, analysis, alarm and storage at industrial sites.
Autonomous inspections are like the human brain, the result of the cooperation of multiple "organs".
Autonomous inspection equipment is used as a carrier. Mechanical equipment is formulated according to the industry and needs. It is also necessary to establish an independent inspection system to collect data through sensors and other equipment, and then set up a certain communication network to transmit the data to the host computer and manage it in the software interface.
The autonomous inspection system is an industrial automation system. Different types have appeared since its development. Typical ones include analog instrument control systems, centralized control systems, distributed control systems, etc., which are also relatively common systems in China at present:
Transmitting analog signals has obvious shortcomings such as low accuracy and weak anti-interference ability. Domestic products have a relatively complete range, the technology is relatively mature, and the use and maintenance experience is relatively rich. However, the system is relatively large, data communication between systems is difficult, and the installed capacity is not very high.
It connects all collection devices to the control center for unified processing, and each collection device does not have the ability to be independently controlled. Its characteristic is that all information flows into the control center and all instructions are issued by the control center, which is suitable for simpler systems.
Also known as distributed control system, it is a comprehensive control system based on microprocessor and integrating various emerging industrial technologies. The core idea of DCS is "centralized management, decentralized control". It connects on-site control stations, operator stations, and engineer stations through a certain communication network to realize centralized monitoring, management, and operation of industrial processes and on-site equipment. Decentralized control.
The application of the system makes a mechanical equipment without life characteristics "smart", which is equivalent to giving the machine "anthropomorphic" inspection capabilities.
In short, it is the process of using automated tools and technologies to monitor and check the operating status and performance of systems, equipment or networks to help improve the reliability and stability of the system, reduce the workload of manual inspections, and timely discover and detect Solve potential problems.
2. What is the operational logic of autonomous inspection?
Autonomous inspection tools regularly collect various indicators and data on systems, devices or networks, such as CPU utilization, memory usage, network traffic, etc.
For example, the "explosion-proof wheeled inspection robot" that has become popular in the chemical industry recently is mainly used in the petrochemical industry, so the R&D unit "Guoxing Intelligent" specially designed a total of 6 carbon monoxide, carbon dioxide, ammonia, methane, oxygen, and hydrogen sulfide gases. For the detection of various gases, in order to increase the accuracy of inspections, various detection functions such as visible light thermal imaging, visual and audio detection, meter identification, and voiceprint detection are also added.
The collected data will be analyzed and diagnosed by autonomous inspection tools to detect whether there are abnormalities or potential problems, and generate corresponding reports or warnings.
The autonomous inspection tool will generate an inspection report, including the system's operating status, performance indicators and discovered problems, and notify relevant personnel in a timely manner so that they can take appropriate measures to repair or optimize.
In some cases, autonomous inspection tools can also perform some automated operations, such as restarting services, cleaning caches, etc., to restore normal operation of the system or optimize system performance.
"At present, the underlying logic of the design of domestic autonomous inspection robots is basically designed according to this logic. Of course, the system can also support access to IoT devices, video surveillance, handheld terminals, robots and other devices to conduct intelligent analysis of data collected by the devices. , to achieve real-time warning and all-round visual operation and maintenance management." explained the R&D engineer of Guoxing Intelligent Explosion-proof Wheeled Inspection Robot.
Not only has it developed a digital three-dimensional inspection system, Guoxing Intelligent also supports multi-platform data aggregation and inspection data on the map, transforming the traditional "multi-platform monitoring + manual recording" into "full-time visual one-map management."
3. What are the advantages of autonomous inspection compared to manual inspection?
The modification of IoT instruments involves modification and meter scrapping, which is costly; the rest is inseparable from manual inspection, which has high costs in terms of manpower, time, economy, and management. The long-term comprehensive investment cost of using the autonomous inspection robot solution is cost-effective.
Traditional manual inspections have different inspection effects due to different inspection personnel. The use of robot inspections not only improves work efficiency, but also solves the problem of scattered inspection quality and single method. Each robot inspection is timed, fixed-point, and fixed. Angle's programmed operations ensure the accuracy and timeliness of inspections, and greatly improve the accuracy and objectivity of inspections.
The entire inspection process is electronicized through robots + inspection recorders + cameras, and combined with AI algorithms to achieve the transformation from "people looking for problems" to "problems looking for people". There are robots to protect no one at night; working 24 hours a day, no matter what happens In the event of an abnormality, the robot will go to the site to verify, without fear of environmental hazards; it will remotely transmit real-time data to assist personnel in analyzing and formulating countermeasures to achieve safe and efficient problem handling.
Compared with fixed video surveillance systems, autonomous inspection robots can flexibly move to any monitoring area as needed, truly realizing all-round monitoring of the computer room. The robot system configuration and task setting are flexible: inspection tasks can be configured at will according to time, content, path, etc.
Compared with other solutions, this system is based on an autonomous inspection robot, which realizes the collection and monitoring of indicators, instruments, infrared, temperature and humidity, noise, gas, dust, etc. in the computer room, and realizes the integration of monitoring methods and tools. and diversity.
Of course, although domestic autonomous inspection robots have developed to a certain level and have been put into use and widely recognized in industries such as petrochemicals and national power grids, there is still more room for improvement in the technical research and development levels of their hardware and software. . For example, whether detection accuracy can be ensured in the face of extremely severe weather, whether automatic detection requires manual review, and whether after-sales maintenance of robot failures can be more convenient. These are all issues that various scientific research companies in the special equipment industry need to face urgently.
Taking Guoxing Intelligent as an example, it has been optimizing its products day by day since 2014, especially the "explosion-proof wheeled inspection robot", which the Guoxing Intelligent R&D team spent a year on through mechanical, electrical, system, and information The intelligent products that have been repeatedly tested and launched by many departments, including production and production, have been put into use in many well-known large chemical plants across the country. It is expected that the robots will be upgraded again in the future to make automatic inspections more "intelligent".
So back to the question itself - whether autonomous inspection is feasible? The answer is "it's worth trying". The development and progress of AI technology provides continuous power for intelligent robots. The integration of technology in the same industry at home and abroad also promotes the rebirth of science and technology. It is believed that autonomous inspection robots can realize all the "possibility" needed by the market in the future.
