Description

Technical Field

[0001] The invention relates to the technical field of inspection and rectification of explosion-proof electrical equipment in explosion-hazardous places, and relates to a traceable system for inspection and rectification of explosion-proof electrical equipment based on explosion-proof RFID tags. Background Art

[0002] Once an accident occurs in an explosion-hazardous area, it will cause casualties and major economic losses. Explosion-proof electrical equipment, as production safety equipment to eliminate ignition sources, is installed in explosion-hazardous areas. Its safe and reliable operation has a direct and significant impact on ensuring safe production.

[0003] Regarding the requirements for explosion-proof electrical inspection, AQ3009-2007 "Electrical Explosion-proof Safety Specifications for Hazardous Locations" Article 7.1.1 General: In order to minimize the ignition risk of electrical equipment used in hazardous locations, they should be initially inspected before the devices and equipment are put into operation and when the project is completed and handed over for acceptance; in order to ensure that the electrical equipment is in good condition and can be used in hazardous locations for a long time, continuous supervision and regular inspections should be carried out. Initial inspections and regular inspections should be entrusted to safety production inspection and testing institutions with explosion-proof professional qualifications. Article 7.1.3.2 Regular inspections: Regular inspections should be entrusted to safety production inspection and testing institutions with explosion-proof professional qualifications, and the time interval is generally not more than 3 years.

[0004] Regarding the requirements for rectification of explosion-proof electrical hidden dangers, AQ3009-2007 "Electrical Explosion-proof Safety Specifications for Hazardous Locations" stipulates that enterprises should take rectification measures in a timely manner based on the inspection results, and file the inspection report and rectification situation with the production safety supervision and management department. The rectification of explosion-proof equipment hidden dangers is the key work of the "National Three-Year Action Plan for Special Rectification of Production Safety".

[0005] Regarding the inspection of explosion-proof electrical equipment, since the on-site explosion-proof electrical equipment has not been fully uniquely identified, this has resulted in inaccurate equipment positioning due to different inspectors during inspections over the years. The inspection results of the same equipment over the years cannot be traced back, and potential hazards cannot be summarized and analyzed.

[0006] Regarding the rectification of explosion-proof electrical equipment, because pictures need to be retained as evidence during the rectification process, and rectification technical information needs to be submitted for review, the current method is to take on-site written records, take photos with explosion-proof cameras, and then go back to print the rectification documents. The corresponding process is cumbersome and prone to errors. In addition, due to the instability of the rectification units and personnel, it is impossible to trace back.

[0007] Therefore, it is urgent to solve the problems encountered in the process of explosion-proof electrical inspection and rectification to truly ensure the inherent safety of on-site explosion-proof electrical equipment.

[0008] Nowadays, Internet technology, big data analysis, cloud computing, Internet of Things technology, etc. have gradually penetrated into various industries, profoundly changing the management and operation mode of traditional industries. In the field of explosion-proof, safety is the first principle. There are many technical fields and industries intersecting, and often one hair moves the whole body, and the technological change is relatively slow. At present, in the field of explosion-proof, product nameplates are often used alone to identify explosion-proof electrical equipment, and the restrictions on the location of the nameplate and the damage of the harsh environment will increase the difficulty for engineers to identify explosion-proof electrical equipment. In addition, the strict requirements for environmental safety also limit the intelligence of the equipment used by engineers during the explosion-proof inspection and rectification process. How to reduce the workload of on-site engineers and improve the efficiency of back-end engineers in processing massive data without increasing the hardware cost of the inspection equipment too much and ensuring the safety of personnel and the environment is a technical problem that technicians in the field need to solve urgently. In addition, the security and traceability of data storage in explosion-proof inspection and rectification are also to be solved by technicians in the field. Summary of the invention
