Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The RTK measuring device 200 of the present invention will be described in detail below with reference to the accompanying drawings. In a conflictless situation In the following, the features of the following embodiments and embodiments may be combined with each other.

Embodiment 1

1 to 12 and FIG. 17, an embodiment 1 of the present invention provides an RTK measuring device 200, which may include a support rod 1, an RTK antenna device 2, a wire (not shown), a backup battery 3, and Control unit 4. The RTK antenna device 2 is mounted on the top end of the support rod 1 and supports the RTK antenna device through the support rod 1. Optionally, the RTK antenna device 2 performs detection based on GPS (Global Positioning System) navigation to obtain coordinate information of a point to be detected. Of course, the RTK antenna device 2 can also be detected based on Beidou or other navigation.

One end of the wire is electrically connected to the RTK antenna device 2, and the other end is provided with an electrical connection member for electrically connecting with the main battery 100, so that the main battery 100 is the RTK antenna device 2 powered by. In use, the RTK antenna device 2 can be powered by the main battery 100 through the plug-in cooperation of the electrical connector and the electrical fitting on the main battery 100, which is convenient and quick. The replacement of the main battery 100 is facilitated by providing an electrical connector. Alternatively, the electrical connector may be an electrical socket or an electrical plug. When the electrical connector is an electrical outlet, the electrical mating component on the primary battery 100 is an electrical plug for mating with the electrical outlet. When the electrical connector is an electrical plug, the electrical mating component on the primary battery 100 is an electrical receptacle for mating with the electrical plug. In this embodiment, the wires are inserted into the support rods 1 to realize wirelessization of the outside of the RTK measuring device 200, preventing the wires from being entangled, thereby improving the service life of the wires and improving the aesthetics of the product.

Further, the backup battery 3 is connected to the support rod 1. The backup battery 3 can be electrically connected to the RTK antenna device 2 to supply power to the RTK antenna device 2. The control unit 4 is configured to enable the backup battery 3 to supply power to the RTK antenna device 2 when the main battery 100 is disconnected from the electrical connector. Specifically, when the main battery 100 is electrically connected to the electrical connector and the RTK antenna device 2 is powered, the backup battery 3 stops supplying power to the RTK antenna device 2. When the battery of the backup battery 3 is lower than the first predetermined amount of power, the main battery 100 charges the backup battery 3. That is, when the power of the main battery 100 is sufficient (the power of the main battery 100 is greater than or equal to the second preset value), the RTK antenna device 2 is powered by the main battery 100, and if the battery of the backup battery 3 is lower than the first preset power. The backup battery 3 is charged by the main battery 100. In the present embodiment, the main battery 100 and the backup battery 3 are also electrically connected by wires. When the main battery 100 is electrically connected to the electrical connector, the main battery 100 is electrically connected to the backup battery 3. The first preset value and the second preset value may be empirical values. Since the RTK antenna device 2 is powered by the backup battery 3 during the disconnection of the main battery 100 from the electrical connector, when the main battery 100 is again electrically connected to the electrical connector, and the RTK antenna device 2 is powered If the backup battery 3 is not charged by the main battery 100 and the main battery 100 is disconnected from the electrical connector for the next time, the power of the backup battery 3 may not be sufficient to support the operation of the RTK antenna device 2, so the present embodiment passes the main battery 100. The battery backup 3 is repeatedly charged, and the backup battery 3 can be repeatedly used to supply power to the RTK antenna device 2, thereby achieving uninterrupted power supply to the RTK antenna device 2, thereby improving work efficiency.

In the embodiment of the present invention, by setting the backup battery 3, the main battery 100 is matched, and the main battery 100 is When the RTK antenna device 2 is disconnected, the RTK antenna device 2 can be powered by the backup battery 3, and when the battery of the backup battery 3 is lower than the first predetermined power, the backup battery 3 is charged by the main battery 100, and the RTK antenna is secured. The device 2 is powered continuously. The use of the backup battery 3 as a temporary source of energy for the RTK antenna device 2 during the replacement of the main battery 100 greatly extends the working time of the RTK measuring device 200 and supports the support of large-area mapping operations.

The backup battery 3 can be connected to the support rod 1 in any manner. For example, in an embodiment, the backup battery 3 can be housed in the support rod 1, preventing the loss of the backup battery 3 and preventing corrosion of the backup battery 3 by moisture in the air.
