Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of communication equipment, and specifically relates to a grounding device RTK communication transmission device. Background Art
[0002] The RTK communication transmission device is applied to the power industry and is mainly used in the scenario of high-voltage power line maintenance.
[0003] During the maintenance of high-voltage power lines, the normal operation process is to first cut off the power of the line to be maintained, and then the maintenance personnel hang the grounding rod attached to the device on the line to be detected. If high voltage is accidentally transmitted, the grounding rod attached to the device will conduct the high voltage into the ground, thus avoiding causing harm to personnel by high voltage.
[0004] Traditional RTK communication transmission devices use a main control MCU, a voice module, a 4G communication module, an RTK positioning module, and a power supply unit to detect whether the grounding rod is hung on the line, avoid incorrect or missed hanging and removal of the grounding rod, and remind on-site operators through an audible and visual alarm. At the same time, information such as the location and operation process is transmitted back to the background management system. However, the existing RTK communication transmission device has a complex and redundant circuit structure, which increases the manufacturing cost and has high operating power consumption.

The output end of the first voltage stabilizing circuit is respectively electrically connected to the audible and visual prompt module and the RTK positioning module. The output end of the second voltage stabilizing circuit is electrically connected to the radio frequency receiving module.
[0009] Furthermore, the RTK positioning module adopts a high-precision positioning module with the model number UM220-IV NK.
[0010] Furthermore, the first voltage stabilization circuit is electrically connected to a level conversion circuit, and the level conversion circuit is electrically connected to the acoustic-optic prompt module and the RTK positioning module respectively.
[0011] Furthermore, the acoustic-optic prompt module includes an LED lamp group for prompting the device status and a voice module for broadcasting voice prompt information. Both the LED lamp group and the voice module are electrically connected to the 4G communication module and the power management module.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] In practical applications, the battery provides power to the power management module and the 4G communication module.

The 4G communication module controls the output of the first voltage stabilization circuit by controlling the enable terminal of the first voltage stabilization circuit according to the signals transmitted by the vibration sensor, thereby controlling whether the acoustic-optic prompt module and the RTK positioning module are powered on for operation, but the radio frequency receiving module connected to the second voltage stabilization circuit remains powered on for communication; if the device remains stationary for a long time, the power supply is turned off, and other functions of the device except the communication function are turned off, entering the low-power mode to reduce the power consumption of the device; this application simplifies the device circuit structure, reduces the production cost, and at the same time performs power management according to the vibration detection of the device to reduce the power consumption of the device.
