<p>When work for LP gas work is to be performed on the basis of a work list to be delivered to the portable terminal of a worker in advance, work errors occur which are caused by the erroneous input of identification numbers of facilities (gas meters, supply facilities, etc.) on which work is to be performed, the time lag between the time of delivery of the work list and the time work is performed, and the like. When identifying a facility on which work is to be performed from a work list, reading a 2D code attached to the facility positioned at the work site and on which work is to be performed prevents the incorrect verification of the facility on which work is to be performed, and allows delivery in real time of work detail data at the time of facility identification.</p> |
