Problems solved by technology

The monitoring of UHV overhead line wire deployment mainly relies on manual inspection, which not only wastes manpower, but also has low accuracy and poor quality of wire laying, which affects the normal use of transmission lines
[0004] In the prior art, there are also some command devices on the construction site of power transmission and transformation projects that use video monitors for monitoring, but limited by weather conditions, the applicability of video monitoring is not good, the monitoring distance is too short, and it cannot be accurately measured The distance traveled by the pay-off board

Embodiment 1

[0029] The invention discloses a real-time command system at the construction site of a power transmission and transformation project. The command system includes a laser ranging device, a wireless signal transmitter 3, a wireless signal receiver 4, a central server 5 with a touch screen display, a handheld mobile Communication terminal; the laser ranging device is a laser transmitter 2 with a distance sensor fixedly installed under the cross-arm of the high-voltage iron tower; the laser transmitter 2 is connected to the wireless signal transmitter 3 through a cable, and the wireless signal transmitter 3 is connected to the wireless signal receiver The device 4 is wirelessly connected, and the output end of the wireless signal receiver 4 is connected with the central server 5 of the command site by cables. The laser distance measuring device in this embodiment also includes a reflective prism mounted on the pay-off board 6 for reflecting the laser light to the distance sensor. ...

Embodiment 2

[0034] This embodiment is improved on the basis of Embodiment 1. In this embodiment, an alarm device connected to the wireless signal transmitter is added. For the specific connection diagram of each device, see image 3 . The alarm can judge the distance between the pay-off board and the next-level high-voltage iron tower according to the distance information sent by the wireless signal transmitter. If there is an abnormality in the pay-out or when the pay-off board is close to the next-level high-voltage iron tower, the alarm will automatically alarm and warn the construction The personnel pay attention to observe the situation of the wire-releasing and board-walking, and can also send an emergency stop signal to the control device of the tractor pulling the wire-releasing and board-walking when an abnormality occurs. This setting ensures the safety of setting-out construction and improves the accuracy of setting-out.

Embodiment 3

[0036] This embodiment is improved on the basis of Embodiment 1 and Embodiment 2. In this embodiment, more than one wireless repeater is set between the wireless signal transmitter 3 and the wireless signal receiver 4. Specifically, each device is connected For a diagram of the relationship, see Figure 4 . Considering that some special construction sites (such as mountainous areas) are not easy to transport the central server 5 to the construction site, so more than one wireless repeater is set between the wireless signal transmitter 3 and the wireless signal receiver 4 for the length of the wireless signal. distance transmission ( figure 1 wireless repeater not shown). The improvement in this embodiment further expands the scope of use of the real-time command system at the construction site of the power transmission and transformation project, and the system can also be used at construction sites such as mountainous areas. During use, the central server 5 and the wireles...

Abstract

The invention discloses a real-time command system at the construction site of a power transmission and transformation project, which belongs to the technical field of power system construction. The command system includes a laser distance measuring device, a wireless signal transmitter, a wireless signal receiver, a central server with a touch screen display, and a handheld mobile communication terminal; the laser distance measuring device is fixedly installed under the cross arm of the high-voltage iron tower with a The laser transmitter of the sensor; the laser transmitter is connected to the wireless signal transmitter through a cable, the wireless signal transmitter is connected to the wireless signal receiver wirelessly, and the output end of the wireless signal receiver is connected to the central server at the command site through a cable; the center The server is also connected with the handheld mobile communication terminal. The invention can accurately judge the distance between the wire-releasing board and the next-level high-voltage iron tower, reduces the labor intensity of command personnel and construction personnel, improves the accuracy of wire-releasing and overall construction efficiency, and ensures the safety of wire-releasing.

Description

technical field [0001] The invention belongs to the technical field of power system construction, and in particular relates to a real-time command system at the construction site of a power transmission and transformation project. Background technique [0002] In the power system, the laying and laying operation of transmission line conductors at the construction site of power transmission and transformation projects is a relatively high-risk work. When laying and laying overhead transmission conductors in the construction of electric power equipment, the construction workers generally rely on the naked eyes of the construction workers to walk the boards Monitor the situation and communicate in real time through the walkie-talkie to ensure the correctness and safety of the construction. [0003] The slacks of the wires of each phase in the same block need to be consistent, and the difference in slack of the wires arranged horizontally should generally not be greater than a p...
