PROBLEM TO BE SOLVED: To solve the problem with a technique for confirming correctness of work done by a worker, where work information is checked and entered in a terminal by the worker and is compared with preloaded work manual information to detect procedural errors, that the technique is susceptible to errors because the work information is entered manually.SOLUTION: A maintenance navigation system of the present invention acquires contents of work done by a worker from sensors, and on the basis of that, determines correctness of the work. After doing any kind of work on a maintenance target device while referring to a mobile terminal, the worker obtains sensor information representing information on sensors that are in the periphery of the maintenance target device and are affected by the work from a database by sending an instruction to determine the contents of the work. The mobile terminal compares the acquired sensor information with expected post-work sensor readings which are pre-registered in the database with a set of rules applicable for each different kind of work to determine whether the work was done properly or not. |
