With reference to FIG. 1 , FIG. 3 , FIG. 7 and FIG. 9 , the first embodiment of the present invention provides an RTK measuring device 200 , which may include a support rod 1 , an RTK antenna device 2 , a support frame 3 , a suspension member 4 , and Wire (not shown). 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. The support frame 3 is connected to the middle of the support rod 1. The support frame 3 of the present embodiment is used to support the support rod 1 so that the support rod 1 can be in an upright state. For example, when the support frame 3 is supported on the ground, the support bar 1 is in an upright state, meaning that the central axis of the support bar 1 is substantially perpendicular to the ground. The suspension member 4 is disposed at the tail end of the support rod 1 for hanging the battery 100 (herein, the battery 100 is a main battery), thereby preventing the battery 100 from being lost, and the battery 100 can also serve as a weight member of the support frame 3. Used, the support frame 3 can be supported more stably on the ground or other support surface.

One end of the wire is electrically connected to the RTK antenna device 2, and the other end is provided with an electrical connection for electrically connecting to the battery 100, so that the battery 100 supplies power to the RTK antenna device 2.

Further, in conjunction with FIGS. 10 through 21, the RTK measuring device 200 may further include a backup battery 5 and a control unit 6. The backup battery 5 is connected to the support rod 1. The backup battery 5 can be electrically connected to the RTK antenna device 2 to supply power to the RTK antenna device 2. The control unit 6 is configured to enable the backup battery 5 to supply power to the RTK antenna when the main battery is disconnected from the electrical connector. Specifically, when the main battery is electrically connected to the electrical connector and the RTK antenna device 2 is powered, the backup battery 5 stops supplying power to the RTK antenna device 2. When the battery of the backup battery 5 is lower than the first predetermined amount of power, the main battery charges the backup battery 5. That is, when the power of the main battery is sufficient (the main battery is greater than or equal to the second preset value), the RTK antenna device 2 is powered by the main battery, and if the battery of the backup battery 5 is lower than the first preset power, the main battery is passed. The battery charges the backup battery 5. In this embodiment, the main battery and the backup battery 5 are also electrically connected by wires. When the main battery is electrically connected to the electrical connector, the main battery is electrically connected to the backup battery 5. 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 5 during the disconnection of the main battery from the electrical connector, when the main battery is again electrically connected to the electrical connector, And when the RTK antenna device 2 is powered, if the backup battery 5 is not charged by the main battery, the battery of the backup battery 5 may not be sufficient to support the operation of the RTK antenna device 2 when the main battery is disconnected from the electrical connector for the next time. In this embodiment, the backup battery 5 is repeatedly charged by the main battery, and the backup battery 5 can be repeatedly used to supply power to the RTK antenna device 2, thereby achieving uninterrupted power supply of the RTK antenna device 2, thereby improving work efficiency.

In the embodiment of the present invention, by setting the backup battery 5 to cooperate with the main battery, when the main battery is disconnected from the RTK antenna device 2, the RTK antenna device 2 can be powered by the backup battery 5, and the battery capacity of the backup battery 5 is lower than When the first preset power is charged, the backup battery 5 is charged by the main battery, which ensures the uninterrupted power supply of the RTK antenna device 2. The backup battery 5 is used as a temporary power source for the RTK antenna device 2 during the main battery replacement process, which greatly extends the working time of the RTK measuring device 200 and supports the large-area mapping operation.
