Technical Field

The invention relates to the technical field of measurement, in particular to an RTK measuring device and method.

Background

In some areas with complex terrain, such as scenic spots, when making a travelator measurement, many local RTKs have no signal due to the blockage of trees. The existing solution is to use a longer centering rod to bring the RTK moving end to the high to enhance the signal.

Because the RTK moving end has a certain weight, when the RTK moving end is sent to a high place, the centering rod is heavy and is inconvenient to carry and use in order to keep the position stable; meanwhile, under the design, the centering rod cannot be too long, the longest centering rod is generally within 8 meters and is lower than the crown height of a higher tree, and signals cannot be effectively enhanced.

Disclosure of Invention

The invention aims to solve the problem of how to carry and effectively enable an RTK receiving end to receive high-altitude signals.

The utility model provides a signal reinforcing removes end based on RTK, includes antenna end and host computer, and characterized by still includes the telescopic link, has the scale on the telescopic link for read the length of telescopic link, the antenna end is located the telescopic link top, the host computer is located the telescopic link bottom, the antenna end is through wired or wireless mode with received signal transmission for the host computer, calculate the position of antenna by the host computer, the telescopic link is vertical during the use, again according to telescopic link length, reachs host computer self position.

The RTK mobile terminal is actually positioned at the phase center of the RTK antenna, so that the RTK antenna and the host can keep a certain distance on the premise of keeping signal connection of the RTK antenna and the host, and the host can be calculated by only determining the distance and the azimuth angle. Because the antenna ends are independent, the antenna ends with light weight only need to be sent to a high position, so the size and the weight of the telescopic rod can be very small, and the telescopic rod is very portable. The telescopic rod is vertical, calculation of angle conversion is avoided, measuring operation is simple, but when a block exists right above a measuring point, the method is not easy to use.

Furthermore, the antenna end is coaxial with the telescopic rod, the axis is the central axis of the telescopic rod in the length direction, and the phase center of the antenna is on the axis.

The phase center position of the antenna is measured by the RTK moving end, and the antenna end and the telescopic rod are coaxial, so that the phase center of the antenna is on the central shaft of the telescopic rod, and calculation of angle conversion is omitted.

Furthermore, the telescopic rod is formed by connecting a plurality of sections of hollow rods in series, the length of the telescopic rod is not less than 8 m after the telescopic rod is completely extended, and a signal transmission line between the antenna end and the host is positioned in the telescopic rod.

Because the weight of the antenna end is very light, the telescopic rod can be made very long, and signals are effectively enhanced; the signal transmission line is located inside the telescopic rod, so that the space inside the telescopic rod is effectively utilized, and the telescopic rod structure is attractive.

Furthermore, the antenna end comprises an antenna and a signal repeater, and the signal repeater forwards the signal received by the antenna to the host computer in a wired or wireless mode.

The antenna end is equivalent to an independent antenna, and the position of the antenna phase center is directly calculated by a host.

Furthermore, the antenna terminal also comprises a power supply for supplying power to the signal repeater or a host power supply, and the host power supply is electrically connected with the signal converter of the antenna by a signal transmission line.

The signal transmission line is used as the wire, so that the weight can be reduced, the structure is simplified, and the production and the use are convenient.

The usage is as follows: a. horizontally fixing the host on the point to be measured; b. opening the host computer, checking whether the signal strength meets the requirements, measuring when the signal strength meets the requirements, and pulling open the telescopic rod when the signal strength does not meet the requirements, sending the antenna to a high position, and enhancing the signal to ensure that the signal strength meets the requirements; c. the host calculates the position of the antenna according to the data returned by the antenna; d. when the telescopic rod is used, the telescopic rod is vertical, the horizontal coordinates of the antenna end and the host are kept consistent, the height of the host is obtained by subtracting the length of the telescopic rod from the height of the antenna end, and the position of the host is determined.

Furthermore, the telescopic rod is formed by connecting a plurality of sections of rods in series, when the telescopic rod is stretched, the upper rod is stretched out completely, then the lower rod is stretched out, and the length of the telescopic rod can be obtained only by reading the scale at the telescopic part of the lowest rod.
