Industry case sharing | Shanghai Metro Line 17 protects daily travel

Indoor rail inspection robot systems are currently widely used in dangerous work sites such as power and chemical industries, such as power distribution rooms, switch rooms, and relay protection rooms. Currently, inspection robots can easily replace manual work to conduct uninterrupted inspections of important or high-risk equipment and harsh environments. Such applications can effectively improve the inspection and maintenance efficiency of power distribution rooms, switch rooms, and relay protection rooms, improve the health level of equipment and the intelligence of operation and maintenance, increase the reliability of power grid operation, and at the same time ensure the safety of operation and maintenance personnel and reduce manual operation and maintenance costs.

01

Project Overview

As an urban rail transit, Shanghai Metro Line 17 starts from Hongqiao Railway Station in Minhang District in the east, passes through Minhang District and Qingpu District, and ends at Dongfang Lvzhou Station in Qingpu District in the west. It is 35.3 kilometers long and has 13 stations, including 7 underground stations and 6 elevated stations. The main content of this case sharing project construction is to install intelligent inspection robots in the 35V/1500V/400V switch rooms of all stations on Shanghai Metro Line 17, making the most of the products and their remote replacement of manual inspection work.

Product composition and system architecture

The Dali intelligent inspection robot supplied for this project consists of a main body, a pan/tilt equipped with a high-definition visible light camera and an infrared thermal imaging instrument, a partial discharge detection module, an environmental monitoring module such as temperature and humidity, and a remote intercom module. The system application effectively improves the inspection and maintenance efficiency of the power distribution room, switch room, and relay protection room, and significantly reduces labor costs while strengthening the health level of equipment and intelligent management of operation and maintenance, ensuring the daily work safety of operation and maintenance personnel.

Project value analysis

[Improve quality and efficiency, reduce costs, and ensure safe and convenient daily travel]

Reduce inspection manual tasks. This indoor rail type adopts a box, rail sliding wire to take power, and is driven by a servo motor. It can achieve 24-hour continuous uninterrupted inspection, reliable operation, no noise, and no need for large-capacity batteries. You can also customize the cycle and equipment for special inspections. It greatly reduces the workload and manpower input of operation and maintenance, increases the reliability of power grid operation, and ensures the safety of citizens' daily subway travel.

[Adapt to local conditions, flexible methods, stable installation]

In response to the different scene requirements of each site, such as the high ceiling of indoor buildings, air conditioning/fire water pipes/ventilation ducts, etc., special installation methods are adopted for each site, such as using a large U-shaped hoisting device to bypass obstacles, and using customized steel structure fixing methods to break through the deployment space limitations and flexibly adapt to different scenes of the entire line;

Since the track system is installed indoors by hoisting and laying tracks, all track profiles are spliced ​​with high-strength alloy tubes. The curvature and slope of the guide rails are planned and designed according to the actual space environment of the distribution rooms, switch rooms, etc. at all stations along the entire line. It has stable installation, high strength, strong load-bearing ability, corrosion resistance, high precision and good movement performance.
