Description

Technical Field

[0001] The invention relates to the technical field of engineering cost, and in particular to an on-site surveying and mapping device and a surveying and mapping method for engineering cost. Background Art

[0002] Engineering project management refers to the management and service of the entire process or several stages of the organization and implementation of the engineering project by an enterprise entrusted by the owner in accordance with the contract agreement on behalf of the owner. Among them, the more important link is the engineering cost link.

[0003] Project cost refers to the construction price of the project. The pricing process requires measurement, valuation and budgeting. When completing the construction project cost, professional engineers are needed at the cost site to use distance measuring instruments or devices to map the site and measure the entire terrain in order to more accurately evaluate the construction project cost.

[0004] Existing on-site surveying and mapping devices for engineering cost generally use laser rangefinders and tripods. When in use, first open the tripod and place it on the ground at the target position, then use bolts to install the laser rangefinder on the top of the tripod, then move the tripod and adjust the length of the tripod legs and the adjustment device of the laser rangefinder in turn until the rangefinder is centered with the surveying and mapping point and is horizontal, then you can start on-site surveying and mapping. During specific operations, the staff can turn on the laser rangefinder and shoot a very thin laser beam at the target. The laser receiver receives the laser beam reflected by the target, and the timer measures the time from the laser beam from emission to reception, so as to calculate the distance from the observer to the target. However, since the laser beam is shot straight, when it is applied to a circular field, the staff needs to frequently adjust the position of the surveying and mapping device for measurement, and the operation needs to be performed manually, which is more troublesome, time-consuming and labor-intensive, and the measurement accuracy cannot be guaranteed.
