Description
[technical field]
The present invention relates to special equipments to examine detection technique field more particularly to a kind of detection efficiency high, intelligence degree
By force, it can accomplish the implementation high-quality, efficient, that inspection is rapidly completed for being applied to special equipment and examining detection.
[background technology]
Current special equipment examines testing agency generally to carry out basis to special equipment using the management software based on computer
The management software of information management and progress related service processing, this " people-computer interaction " pattern is difficult to meet current special type to set
The sharp increase of standby quantity and society are mainly manifested in the higher security performance demand of special equipment:
(1) special equipment identity used at present has shortcoming.Such as the label of common papery and steel, need
It with the naked eye reads, the efficiency of reading is low, is easy error.In special equipment onsite application, it is easy to fade and wear, cause
Special equipment accession designation number None- identified.
(2) information such as the inspection original record at reviewer scene can not manage system in first time typing, can only return
By being manually entered after office, supervision can be delayed in this way and examine the timeliness of work, led to not in first time to not conforming to
Lattice equipment is supervised, and there are great security risks.
(3) when examining at the scene, can not the archived special equipment essential information of real time review and modification information, this gives
Scene discriminates whether that there is illegal transformation and overhaul behavior brings larger difficulty.By manual identified it is difficult to find registered set
Standby or distinguish illegality equipment, assembled equipment, work difficulty and workload are all larger, and reliability is also poor, slightly neglect just
It will appear error, undertake larger liability exposure.
(4) quantity of special equipment is man-machine very more prominent than contradiction in rapid growth, and device distribution region is wider,
This significantly increases the time that special equipment reviewer reaches work on the spot, causes working efficiency low.
Current special equipment inspection process is generally as follows：
(1) test condition confirms.Reviewer, which reaches, examines scene, confirms to Subscriber Unit scene preparation,
It if scene is unsatisfactory for examination requirements, terminates and examines, and provided " examining Action " to user.
(2) original record is filled in field test.Inspection content includes：Technical data access, static check, electric checking,
Dynamic chek, no-load test, load performance experiment etc..
(3) check conclusion comprehensive judgement.Reviewer carries out comprehensive judgement according to inspection result item by item, and judgement conclusion is conjunction
Lattice are unqualified.
(4) reviewer returns to unit, and formal survey report is provided according to the data and original record collected.User hands over
Survey report and the quality certification are got after expense.
In today of social high speed development, the fast working day for making special equipment examine detection of special equipment growth rate
Gradually heavy, man-machine contradiction is increasingly prominent.How could thoroughly change previous inspection operating mode, accomplish high-quality, efficient, quick
It completes to examine, effectively solves the growing contradiction with inspection body's shortage of manpower of special equipment quantity, be the technology of this field
Personnel often consider the problems of.
