Technical Field

[0001] The invention belongs to the field of equipment identification, and in particular relates to a nuclear power plant equipment information identification system. Background Art

[0002] Equipment identification is installed on many nuclear power equipment. The existing system equipment identification is an ordinary identification, which only presents "equipment KKS code and equipment Chinese name" and can only be viewed visually.

[0003] There are many defects in the existing identification method, as follows: the staff can only view the KKS code and name through the identification, which has a certain degree of singleness. The ordinary identification method cannot be managed intelligently and a data platform cannot be established, thereby failing to improve the efficiency of personnel in discovering and handling defects in daily work. The existing identification cannot form an intelligent management method, which is inconvenient for the staff to view the equipment and is prone to human errors. The existing identification cannot enable the staff to quickly obtain equipment-related information through the intelligent system. It has a single function and poor flexibility, making it inconvenient for the staff to operate and use.

[0004] Therefore, it is urgent to develop an electronic intelligent identification to solve the problems existing in the existing identification methods. Summary of the invention

[0005] The purpose of the present invention is to provide a nuclear power plant equipment information identification system, which can ensure that the identification still maintains a stable radio frequency signal in a metal environment and can be used normally in the metal environment. At the same time, it can quickly obtain equipment-related information, effectively improve the informatization level of on-site operation work, greatly reduce human errors, and ensure the safe operation of the unit.
