work detailed data delivery system and method of the LP gas business by two-dimensional code reading

摘要

PROBLEM TO BE SOLVED: To solve the problem that, in an LP gas service, when work is performed in accordance with a work list previously delivered to a portable terminal of a worker, mistakes in work are caused by an incorrect input of an identification number of a work object facility (gas meter, supply facility, or the like), time lag between work list delivery and work, or the like.SOLUTION: When a work object facility is identified from a work list, a two-dimensional code attached on the work object facility installed in a work site is read. Thus, false recognition of the work object facility is prevented, and, at that time, work detailed data is delivered in real time.
