The inspection work of the equipment is an important measure to ensure the smooth operation of the equipment. The inspection is a time-sensitive work, and the on-duty personnel must periodically inspect each inspection point. However, manual inspections make it difficult to effectively supervise on-duty inspection personnel, resulting in frequent accidents caused by inadequate inspection reports and untimely troubleshooting. In addition, paper inspections cannot transmit real-time inspection data. The faults are not handled in time, affecting the safe and effective operation of all types of equipment.
Program overview
Using RFID technology and wireless LAN to carry out equipment and pipeline inspection, usually used in electric power, manufacturing enterprise equipment inspection, petrochemical pipeline inspection. Cover the seamless wireless network along the inspection route in the plant area, and install an RIFD label at each inspection monitoring point. The label records the basic information of the inspection monitoring point. Every time the inspection personnel first reads the contents of the label with the handheld device at a patrol inspection point, the equipment and pipeline are inspected, and the detection information is transmitted to the management office through the wireless network. A patrol management system is established in the background to ensure the inspection quality of the inspection personnel through the system, improve the management level of the equipment being inspected, improve the inspection efficiency, and gain insight into the entire inspection work.
Industry demand
Petroleum refinery equipment and pipeline inspection refers to the regular inspection and inspection of the equipment and pipelines of the equipment security inspection department to ensure the safety of oil transportation and refining. For a long time, the inspection work of refineries has been following the "one-table" approach. The inspection personnel inspect the equipment and pipeline according to the inspection route, and then select the operation status on the form and return to the management office for statistical inspection. Due to factors such as lack of responsibility of the inspectors and weather conditions, the inspectors are sometimes lazy and falsely report the inspections, which makes the quality of the safety inspection work greatly reduced.
system design
The equipment inspection system based on RFID technology mainly includes inspection dispatch management, inspection line management, inspection information download management, inspection information upload management, inspection information query management, and inspection information report management. The hardware device is mainly composed of an RFID handheld terminal, an RFID electronic tag, and a wireless access point. In the design of this system, it closely surrounds the core needs of the industry and the key business processes of inspection operations, and closely combines the applicability of RFID technology in actual needs, such as the use of ultra-high frequency passive electronic for the selection of electronic tags. For the label, the corresponding reading distance is also large, so that the information of the electronic label can be accurately detected.
Inspection business operation process
(1) Place an RFID tag at the existing inspection and inspection point, and the label is initialized to record the basic information of the inspection and inspection point, such as the inspection number and inspection location;
(2) Establishing an inspection management information system, conducting various business management through the system, and internship, operation, management, statistics and analysis of various inspection services on the system;
(3) When there is a plan for inspection, the plan will be entered into the system, such as the inspection personnel, inspection route, departure time, requirements, etc., and then the inspection task will be sent to the RFID handheld reader, and then the inspection personnel set off;
(4) The inspection personnel will start the inspection according to the inspection task, and the RFID reader will be close to the inspection inspection point at the inspection point, and the detection situation of the inspection personnel can be automatically recorded;
(5) The status and results of the inspection can be uploaded to the management information system in real time through the wireless LAN network, or returned to the management center to upload the inspection data to the management information system;
(6) The management center can view the completion of the inspection plan through the management information system, and can query and print the corresponding inspection statistics.
The inspection equipment system fully utilizes the physical advantages of RFID technology, mainly utilizing the characteristics of UHF RFID without contact and long reading distance, without manual intervention, thus improving the convenience of inspection personnel and greatly reducing the inspection. The workload of the inspectors. Long reading distance can realize long-distance data collection, better remote equipment inspection; RFID recognition speed is fast, reduce a large number of inspection time, improve efficiency, improve the management level of equipment inspection; RFID technology can be appropriate The material that penetrates the cloth, the skin, and the wood is read, and can fully cope with the challenges of the harsh environment and maintain the work around the clock.
What's important is that RFID technology brings real-time and accurate data, enabling managers to gain insight into data and turn this insight into a business management best practice that improves management and forecasting capabilities and promotes overall Efficiency and management improvement.
Case——Sinopean Oilfield Asset Intelligent Management Project
Oilfields are industries with complex operation processes and severe production environments. There are countless types and quantities of equipment that keep the oilfields functioning properly. At present, most of the domestic oilfields use manual recording and bar code or laser marking to combine asset identification and management. However, manual management is inevitable. After a long time, the original information is easily lost. According to reliable statistics, the cost of asset management in oilfields reaches several billions per year. The reason is that the existing management methods are not suitable for the complex and harsh working environment of oil fields. The assets are exposed to the outdoors, except that they need to withstand the sun and rain. Assets are also often affected by a variety of factors including high temperatures, chemicals, oil, pressure and impact. Bar code and laser marking cannot withstand such a harsh environment. Only industrial grade UHF RFID solutions can meet the oil field. Environmental applications.
In the next few years, the oilfield plans to carry out RFID applications for most of its related well-proof wells, oil pipelines and other related assets. Currently, the first batch of pilot applications of one type of assets will be implemented. The main purpose of the application is to record all the important information during the entire service period from the purchase to use through the specially developed software system by installing RFID tags on the assets, including: asset purchase time, name of the person in charge, supplier Information and price; use of assets, maintenance and repair, inventory records; periodic inspection records of assets, information of responsible persons, etc. More importantly, RFID technology enables the staff to locate and monitor the status and location of the assets, so that the staff can always grasp the detailed use of the assets, avoiding the inability to use the assets due to information asymmetry, causing greater losses.
Through the use of RFID solutions, the management efficiency of the asset in the oilfield has been greatly improved, and the data obtained is more accurate and timely than before. The relevant person in charge said: “Compared with the past management methods, the benefits brought by RFID are very satisfactory. If applied on a large scale, the asset management costs of the oilfield will be greatly reduced."
Highlights of this application case:
Scale: Sinopec Oilfield has installed all types of assets and implemented systematic management; and plans to expand RFID applications for various types of asset equipment in the next few years.
ROI: The annual cost of asset management in oil fields is staggering. By using RFID, not only the efficiency of asset management is improved, but also the management cost is greatly reduced by increasing the utilization rate of asset equipment.
Representative: Oil and gas development has always been at the forefront of RFID applications, and is also very suitable for the application of RFID technology. Its return on investment has a profound impact on improving the visibility of internal information, improving management efficiency, improving service quality and meeting industry safety standards. significance.
