Description

Technical Field

[0001] The present invention belongs to the technical field of informatization of thermal power plants, and particularly relates to a method, a system, a device and a medium for checking the conflict of safety measures of work tickets in thermal power plants. Background Art

[0002] When performing maintenance or repair operations on various types of equipment in a thermal power plant, it is necessary to handle and hold electrical or thermal mechanical work tickets as work basis; among them, safety measures are one of the main contents of work tickets. After the safety measures of the work ticket are implemented, the equipment to be maintained or repaired can be in a condition for maintenance or repair; after the operation task is completed, the safety measures need to be restored in time; when the operation task is not completed and the safety measures are not fully implemented or some measures are restored after being implemented, potential safety hazards will be left. If the operation task continues, serious unsafe events may occur.

[0003] The correlation between various equipment in a thermal power plant is relatively strong. Different personnel often hold their own work tickets to carry out maintenance or repair operations on the same or similar equipment. Inevitably, there will be some situations where some safety measures are exactly the same. Due to different operation tasks, some tasks end earlier and some tasks end later. And multiple operation personnel may not have sufficient communication. If all the safety measures are restored after the tasks that end earlier are completed, and the remaining personnel who have not completed the operation tasks are not aware of it and continue to perform the operation tasks, serious accidents may be caused due to the incorrect restoration of the conflicting safety measures between multiple work tickets.

[0004] At present, the inspection of conflicting safety measures between multiple work tickets mainly relies on the manual records of on-duty operation personnel. Such a method is not only cumbersome to record, but also may be omitted due to human factors (exemplarily, such as incomplete records, unclear instructions during shift handover, etc.). Summary of the Invention

[0005] The purpose of the present invention is to provide a method, a system, a device and a medium for checking the conflict of safety measures of work tickets in thermal power plants to solve one or more of the above-mentioned technical problems. In the present invention, the association of safety measures is realized based on semantic similarity analysis, which can reduce the workload of on-duty personnel and avoid the technical problems of incorrect restoration of safety measures caused by incomplete records, unclear instructions during shift handover, etc.

[0011] The conflict reminder when the work ticket safety measures are restored includes the following steps:

[0018] From the safety measure sequences having a degree of similarity greater than a preset semantic similarity threshold, determinedly repeated safety measures are screened and obtained.

[0019] A further improvement of the method of the present invention is that the step of associating the to-be-executed security measure with the acquired executed security measure specifically comprises:

[0020] When establishing an association between the to-be-executed security measure and other repeated security measures, one repeated security measure is associated; wherein, when multiple security measures are repeated with each other, the remaining association relationships are indirectly established through the association chain established before.
