Description

Technical Field

[0001] This utility model relates to the field of conductor safety protection technology, and in particular to a conductor anti-external damage monitoring device based on Beidou positioning. Background Technology

[0002] Power transmission lines are constructed by using transformers to step up the voltage of electricity generated by generators, which is then transmitted to the power lines via circuit breakers and other control equipment. Structurally, power transmission lines are divided into overhead transmission lines and cable lines. During the construction of power transmission lines, especially in areas where construction vehicles are operating beneath them, ensuring the safety of personnel and equipment is paramount.

[0003] Existing safety measures largely rely on manual control and simple alarm systems. The on-site operations supervisor needs to know whether each construction vehicle is operating within the permitted construction area, as well as the precise location of the crane booms on the construction vehicles and be able to access historical data on accidents.

[0004] However, the traditional voice communication protection methods currently used, such as walkie-talkies and dedicated protective mobile phones, have two limitations. On the one hand, the on-site construction supervisor cannot accurately and in real time grasp the position of the top of the boom of the engineering vehicle under the power transmission line. On the other hand, the on-site operation supervisor cannot intuitively understand the historical position of each engineering vehicle inside and outside the work area, nor can they trace the historical data of the engineering vehicle boom at various times. Therefore, there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a BeiDou-based conductor protection device for external damage monitoring. Its advantages include an onboard terminal that immediately alarms when the boom of a construction vehicle approaches the conductor or when the vehicle leaves the designated safe working area. This provides the on-site supervisor with monitoring of the vehicle's location within and outside the designated work area, as well as a historical vehicle trajectory lookup table, thus ensuring the safety of construction vehicles.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A wire damage prevention monitoring device based on BeiDou positioning includes a housing, a power switch button on the front of the housing, and is characterized in that a GNSS antenna is connected to the top of the housing via a detachable mechanism, 4G antennas are provided on both sides of the housing, and a PCB circuit board is fixedly connected to the inside of the housing by bolts; a calibration button is provided on the outer wall of the housing below the power switch button.

[0008] The above technical solution involves: placing the equipment in the designated location, pressing the power switch to turn it on, and then pressing and holding the calibration button to perform a coordinate calibration. After multiple calibrations, the area enclosed by each calibration point is the fence working area. A laser rangefinder is used to measure the distance from the sag point of the conductor to the ground. The operator fixes the equipment to the top of the vehicle's boom. After the equipment is started, the 4G antenna connects to the server and the differential server. After successful connection, the GNSS antenna interacts with the satellite to obtain raw positioning data. Then, the 4G antenna interacts with the differential server to obtain RTCM data. The positioning device performs differential processing on the raw data. The 4G antenna sends the differential positioning data to the background data processing center and compares the received data with the conductor distance warning threshold and the fence working area to determine whether it exceeds the warning standard. When the engineering vehicle boom approaches the conductor or the engineering vehicle leaves the safe working area fence, the vehicle terminal immediately alarms.

[0009] The present invention is further configured such that the detachable mechanism includes a GNSS antenna fixing port provided on the top of the housing, the outer wall of the GNSS antenna fixing port is provided with a second thread, the GNSS antenna fixing port is connected to a rotating fixing ring through the second thread, the bottom of the GNSS antenna is provided with a first thread, and the rotating fixing ring is connected to the GNSS antenna through the first thread.

[0010] With the above technical solution, when installing a GNSS antenna, simply align the bottom of the GNSS antenna with the GNSS antenna mounting port, then rotate the rotating fixing ring. Once the rotating fixing ring is connected to both the GNSS antenna and the GNSS antenna mounting port, the GNSS antenna can be fixed in place, improving the ease of operation.

[0011] The present invention is further provided that the outer surface of the rotating fixing ring is provided with anti-slip protrusions, and the anti-slip protrusions are integrally formed with the rotating fixing ring.

[0012] The above technical solution, with its anti-slip protrusions, increases the friction between the fingers and the rotating ring, preventing slippage during rotation.

[0013] The present invention is further configured such that a charging port is provided on the outer wall of the housing below the power switch button, and a storage battery is provided inside the housing, and the charging port is connected to the storage battery.

[0014] The above technical solution allows for convenient charging of the battery, improving the ease of power supply to the device.

[0015] The present invention is further configured such that the surface of the housing is provided with multiple status indicator lights, including a power indicator light, a GNSS antenna indicator light, and a 4G indicator light.

[0016] The above technical solutions enable the power indicator, GNSS antenna indicator, and 4G indicator to show the working status of the power supply, GNSS antenna, and 4G antenna, respectively, allowing people to understand the working status of the device in a timely manner.

[0017] The present invention is further provided with a power indicator light on the outer wall of the housing below the calibration button, wherein the number of lit lights in the power indicator light represents the level of power.

[0018] Through the above technical solutions, the setting of the power indicator light allows people to easily monitor the battery power in a timely manner, and charge it promptly when the power is low, ensuring that the device can work normally.

[0019] The beneficial effects of this utility model are as follows: This Beidou-based conductor damage prevention monitoring device allows for coordinate calibration by placing the device in a designated location, pressing the power switch, and then pressing and holding the calibration button. After multiple calibrations, the area enclosed by the calibration points becomes the fenced working area. A laser rangefinder is used to measure the distance between the conductor sag point and the ground. The operator fixes the device to the top of the vehicle's boom. After the device is started, the 4G antenna connects to the server and the differential server. Once the connection is successful, the GNSS antenna interacts with the satellite to obtain raw positioning data. Then, the 4G antenna interacts with the differential server to obtain RTCM data. The positioning device performs differential analysis on the raw data, and the 4G antenna sends the differential positioning data to the background data processing center. The center then compares the received data with the conductor distance warning threshold and the fenced working area to determine whether the warning standard has been exceeded. When the engineering vehicle's boom approaches the conductor or the engineering vehicle leaves the safe working area fence, the on-board terminal immediately alarms. This provides the on-site work supervisor with the ability to monitor the engineering vehicle's location inside and outside the designated working area and to query historical vehicle movement trajectories, ensuring the safety of construction vehicles.

A storage battery is installed inside the housing 11, and the charging port 6 is connected to the storage battery.
