[0026] To better understand this utility model, the content of this utility model is further explained clearly below with reference to the embodiments and accompanying drawings. However, the protection scope of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0027] Example 1: See Figure 1 The purpose of this embodiment is to provide a substation maintenance construction site management and control system, including a tethered drone 1, a ground station 2, and a control terminal 3.
[0028] The tethered drone 1 is electrically connected to the ground station 2 via a tether cable. The ground station 2 supplies power to the tethered drone 1, enabling it to hover and operate continuously for extended periods. The tethered drone 1 is equipped with a camera 11 and a light 12. The camera 11 is used to acquire video information of the work site while the tethered drone 1 is hovering, and the light 12 is used to provide illumination for the work site at night. The ground station 2 is powered by 220V AC.
[0029] The tethered drone 1 is equipped with a drone speaker 13, and the ground station 2 is equipped with a ground speaker 21. Both the drone speaker 13 and the ground speaker 21 are used to play sound to the work site.
[0030] The control terminal 3 includes a display screen 31. The control terminal 3 is communicatively connected to the tethered drone 1 and the ground station 2. It is used to control the tethered drone 1 and the ground station 2, to acquire video information from the camera 11 on the tethered drone 1 and display it on the display screen 31, to control the drone speaker 13 and the ground speaker 21 to emit alarm sounds, to collect sound signals and send them to the tethered drone 1 in real time and play them through the drone speaker 13, and to collect sound signals and send them to the ground station 2 in real time and play them through the ground speaker 21.
[0031] The control terminal 3 can be a handheld terminal such as a mobile phone or tablet, or a computer device. The computer device control terminal 3 can be installed in the substation monitoring center or in a mobile on-site control unit, where staff will monitor and manage it. The monitoring center or control unit is equipped with a smart management platform for controlling personnel, vehicles, and tools at the substation maintenance site. The smart management platform utilizes this invention to achieve dynamic control of on-site personnel. Staff observe the work site through the display screen 31. If any staff member is found to be misaligned, overstepping boundaries, or engaging in misoperation or other violations or dangerous behaviors, staff can issue voice alerts via the drone speaker 13 and the ground speaker 21 to remind on-site staff to pay attention.
[0032] Example 2: In some substation maintenance and construction sites, the power supply is completely cut off. At this time, ground station 2 is powered by a portable generator, and other power needs at the work site are also met by the portable generator. Therefore, the input voltage of ground station 2 may be unstable, and power outages may even occur. To address this situation, the substation maintenance and construction site management system provided in this example has been improved compared to Example 1 in the following ways: a backup power supply 23 is also installed in ground station 2.
[0033] The backup power supply 23 has a built-in battery for outputting DC power. The AC power input from the ground station 2 is converted into DC power required by the tethered UAV 1 via the AC-DC module 25, and the power output from the backup power supply 23 is converted into DC power required by the tethered UAV 1 via the DC-DC module 26. Simultaneously, a switching module 24 is also provided between the AC input port and the AC-DC module 25, and between the backup power supply 23 and the DC-DC module 26. The switching module 24 is used to automatically connect the power supply line between the backup power supply 23 and the DC-DC module 26 when the AC input is interrupted or the voltage is too low, and to automatically disconnect the power supply line between the backup power supply 23 and the DC-DC module 26 after the AC input is restored.
[0034] The switching module 24 can be implemented using an AC-controlled DC normally closed solid-state relay, or it can be implemented using... Figure 3 The circuit shown is implemented. Figure 3 In this configuration, the input terminal of rectifier bridge D1 is connected in series between the AC input terminal of ground station 2 and AC-DC module 25. The input AC power is converted to DC by rectifier bridge D1, and after being voltage limited and filtered by resistor R1 and capacitor C1, it is input to the trigger terminal of normally closed solid-state relay Q1. The control terminal of solid-state relay Q1 is connected in series between backup power supply 23 and DC-DC module 26. When the power supply to voltage regulator module 22 is interrupted or the voltage is too low, the normally closed solid-state relay automatically closes its control terminal, and backup power supply 23 automatically connects to start supplying power. When the AC input of ground station 2 is restored, the normally closed solid-state relay automatically closes its control terminal, and backup power supply 23 is disconnected.
[0035] The backup power supply 23 is also electrically connected to the AC input port via the charging module 22, which can charge the backup power supply 23.
[0036] Example 3: The substation maintenance construction site management and control system provided in this example has the following main improvements compared with Example 1 or Example 2:
[0037] Control terminal 3 is also used to set up a virtual electronic fence at the work site. Based on the video feed from tethered drone 1, staff set up an electronic fence at the work site within the video feed. The electronic fence is used to demarcate dangerous or prohibited areas.
[0038] The control terminal 3 is also used to determine whether workers have crossed the designated virtual electronic fence. The control terminal 3 monitors the video information of the tethered drone 1 in real time, and immediately issues an alarm when it detects a worker crossing the electronic fence. The alarm information can be sent directly through the drone's speaker 13 and the ground speaker 21 to alert on-site workers.
[0039] The methods for setting up virtual electronic fences and identifying personnel locations based on video footage are common knowledge or conventional techniques in this field or related fields (such as video surveillance), and will not be elaborated further. Those skilled in the art, combined with common knowledge and conventional techniques, can understand the implementation method of this embodiment.
[0040] It should be noted that the main improvements of the technical solution protected by this utility model are in the mechanical and hardware parts. Although some mechanical or hardware functions are implemented by computer programs, the computer programs involved are all known. Therefore, the technical solution protected by this utility model is subject to utility model patent protection.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
