However, since this trouble report only records actual trouble phenomena, it may not be possible to solve it only with the information in this trouble report. A solution request is made to the vendor. In response to this, the equipment vendor collects trouble information using a telephone or a facsimile at the time of occurrence of the trouble and recovers the information by using the collected information. However, in many cases, the situation of the trouble actually occurring cannot be accurately grasped.

[0004] In addition, a video camera is installed for continuous monitoring of troubles which occur very rarely and production facilities whose operation conditions are complicated. However, from the image data taken for such a long time, a great deal of time and effort was required to analyze the trouble.

[0005] Further, as the types of production facilities developed one after another increase, the number of trouble analysis methods corresponding to these increases, and there is a tendency that trouble analysis of desired production facilities cannot be performed efficiently. Also, after the development of production equipment, troubles that occur several years later may not be able to be dealt with due to the absence of a person in charge, and the trouble resolution report created by solving the problem is not the content that can be seen by a third party, Trouble causes and solution know-how are not shared, so they cannot be effectively used for another production facility.
As a result, a similar trouble occurs, and it takes time to solve the trouble in the same manner.

[0006] On the other hand, in the equipment inspection, a manual inspection is required by the maintenance staff on site to comprehensively judge the data collected from the movement and sound of the production equipment, the control device, and the like. At present, automation has not progressed.

Therefore, the present invention focuses on providing a report created by an operator with a reproducing function of reproducing not only character information but also actual moving images and audio information, and records the operation of monitored equipment. The purpose of the present invention is to provide a logging device, a logging system, and a logging report capable of accurately reproducing the operation of monitored equipment required for trouble analysis by providing a retrieval report information for retrieving information in a logging report. And
