Description
Technical Field
[0001] The utility model relates to the technical field of building cost information input, in particular to an input comparison device. Background Art
[0002] The cost of a construction project generally refers to the cost of carrying out the construction of a certain project, that is, all the costs from preparation to completion, acceptance and delivery. When a cost engineer estimates the cost of a construction project, he often needs to find one or several similar projects in previous projects, and then make a subjective evaluation based on the cost difference and cost time difference of the dissimilar parts. In order to facilitate the cost comparison of cost engineers, the cost sheets of multiple projects need to be entered into the cloud to complete a convenient comparison. In order to facilitate the entry of the cost sheet, corresponding devices are often required. When the existing entry and comparison device scans and enters the construction cost sheet, it is necessary to put a cost sheet on it, remove it after the entry is completed, and replace it with another one. It needs to be fixed when placing and taking it. Since the cost sheet usually has more files, such operation will greatly affect the entry efficiency, and a faster speed is also required to ensure the entry efficiency. Utility Model Content
