chrispeng [ad_1]
The inspection of equipment is an important measure to ensure the smooth operation of the equipment. Inspection is a time-sensitive work, requiring personnel on duty to periodically inspect every inspection point. However, manual inspections make it difficult to effectively supervise the on-duty inspection personnel, resulting in various accidents caused by inadequate inspection reports and failure to handle failures in time; in addition, paper inspections cannot transmit real-time inspection data, which will As a result, the fault processing is not timely, which affects the safe and effective operation of various equipment.
Program overview
Use RFID technology and wireless local area network to carry out equipment and pipeline inspections, which are usually used for equipment inspections of electric power and manufacturing enterprises, and petrochemical pipeline inspections. A seamless wireless network is covered along the inspection route in the factory area, and an RIFD tag is installed at each inspection and monitoring point, and the tag records the basic information of the inspection and monitoring point. After each inspection point, the inspectors first use the handheld to read the tag content, then inspect the equipment and pipelines, and transmit the inspection information to the management office through the wireless network. A patrol inspection management system is established in the background to realize the work quality inspection of patrol personnel through the system, improve the management level of the equipment being inspected, improve 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 in the plant by the equipment security inspection department to ensure the safety of oil transportation and refining. For a long time, the inspection work of the refinery has been using the “one meter” work method. The inspectors inspect the equipment and pipelines according to the inspection route, then select the operation status on the form, and return to the management office to count the inspection status. Due to factors such as weak sense of responsibility and weather conditions, the inspectors are sometimes lazy and falsely report the inspection situation, which greatly compromises the quality of the safety inspection work.
system design
The equipment inspection system based on RFID technology mainly includes inspection dispatch management, inspection route management, inspection information download management, inspection information upload management, inspection information query management, inspection information report management, etc. The hardware equipment 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 focuses on 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. For example, the selection of electronic tags uses ultra-high frequency passive electronics. For tags, the corresponding reading distance should also be larger, so that the information of the electronic tags can be accurately detected.
Inspection business operation process
(1) Place RFID tags at the existing inspection points, the tags are initialized, and record the basic information of the inspection points, such as the inspection number and the inspection location;
(2) Establish a patrol inspection management information system, manage various businesses through the system, and practice the operation, management, statistics, and analysis of various patrol inspection services on the system;
(3) When there is an inspection plan, enter the plan into the system, such as inspection personnel, inspection route, departure time, requirements, etc., and then send the inspection task to the RFID handheld reader, and then inspect the personnel Set off;
(4) The inspector starts the inspection according to the inspection task, and moves the RFID reader close to the inspection point at the inspection point to automatically record the inspection status of the inspector;
(5) The situation and results of the inspection can be uploaded to the management information system in real time via the wireless LAN network, or it can be 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.
System advantages
The inspection equipment system makes full use of the physical advantages of RFID technology, and mainly uses the characteristics of UHF RFID without contact, long reading distance, and without manual intervention. This improves the convenience of inspection personnel and greatly reduces inspections. The workload of inspectors. Long reading distance can realize long-distance data collection, and better realize long-distance equipment inspection; RFID recognition speed is fast, reducing a lot of inspection time, improving efficiency, and improving the management level of equipment inspection; RFID technology can be appropriate Penetrate cloth, leather, wood to read that material, and can fully cope with the challenges of the harsh environment, and maintain all-weather work.
The important thing is that RFID technology brings real-time and accuracy of data. For managers, they can obtain insights from the data, and convert this insight into a best practice of business management, improve management level and predictive ability, and promote the overall Improved efficiency and management.
Case study ——Sinopec Oilfield Asset Intelligent Management Project
Oil fields are an industry with complex operating processes and harsh production environments. There are countless types and numbers of equipment that keep the oil fields operating normally. At present, the vast majority of domestic oilfields use a combination of manual recording and bar code or laser marking for asset identification and management, but manual management is unavoidable to make mistakes, and the original information is easy to lose over time. According to reliable statistics, the cost of asset management in oil fields reaches several billions every year. The reason is that the existing management methods are not suitable for the complex and harsh operating environment of the oil fields. Assets are also often affected by various factors such as high temperature, chemicals, oil pollution, pressure and impact. Barcode and laser marking simply cannot withstand such a harsh environment. Only industrial-grade UHF RFID solutions can meet the requirements of oilfields. Environmental applications.
The oilfield plans to implement RFID applications on most of its blowout-proof wells, oil pipelines and other related assets in the next few years. Currently, it is the first batch of pilot applications for one type of asset to be implemented. The main purpose of this application is to install RFID tags on assets, and use a specially developed software system to record all important information of the assets from purchase to use and the entire service period. These information include: asset purchase time, name of the person in charge, and supplier Information and prices; use, maintenance, and inventory records of assets; regular inspection records of assets, information about the person in charge, etc. More importantly, RFID technology enables staff to locate and monitor the status and location of assets, enabling staff to keep abreast of the detailed use of assets at all times, and avoid the unavailability of assets due to information asymmetry, causing greater losses.
Through the use of RFID solutions, the oilfield’s management efficiency of the assets 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. Yes, if applied on a large scale, it will greatly reduce the annual oilfield asset management costs.”
Highlights of this application case:
Scale: Sinopec Oilfield has installed tags for all assets of one type to realize systematic management; and plans to expand the application of RFID for various types of assets and equipment in the next few years.
ROI: The annual cost loss of the oil field in asset management is staggering. By using RFID, not only the efficiency of asset management is improved, but 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 it is also a field that is very suitable for RFID technology applications. Its return on investment has far-reaching effects on improving the visibility of corporate internal information, improving management efficiency, improving service quality, and meeting industry safety standards. significance.
