In operational work, if a set of system for real-time monitoring staff position, to enhance the security of the site work, and optimize work deployment and process have important role,
The role of one of the most intuitive is that when a foreign construction or outsourcing operations staff, location distribution of these workers, if it is meaningful to have can be real-time monitoring,
It's easy to think of the GPS positioning system, but the GPS positioning results can only provide the latitude and longitude information, error in dozens of meters, can know what target is roughly in scope,
However, GPS positioning information can not meet the requirements of wind farm management, mainly for two reasons:
One is that the height information error is too large, such as it can't tell you were in the bottom or on the engine room, because the error is too great, and in different geographic regions effect may not be the same;
The second is, in some circumstances, especially within the building GPS signal will be weak or no, lead to locate the failure,
Site or within the indoor positioning technology has been developing, at present, the accuracy and the cost is more suitable for the application of wind farms is a called a UWB technology, full name is the UWB (Ultra Wide Band) wireless location technology, it is the main principle of the target (TAG) to locate the Anchor point (Anchor) launch the nanosecond Ultra narrow pulse, the arrival time is used to calculate the distance between two points; This target by calculation and four anchors from target space position can be calculated,
The GPS positioning error can be controlled within a few centimeters, for application and can meet the personnel positioning,
Application in wind farm, actually we locate the key, is want to know, and our key equipment, the relative position in the system,
Therefore, we can in the engine room of wind turbines, bottom and box deployment positioning anchor, plus booster station of each main location,
After deployment, and approach equipped with positioning chip tags, can real time control of whole each key position of the personnel distribution,
Considering the special case of wind farm, units distributed in dozens of kilometers, within the scope of the positioning anchor cover is not complete, can be combined with GPS locate the blind area completion,
In this way, a complete personnel positioning system was finished,
