According to Sinochem New Network, the project to build a new substation for the 35,000 tons per year nitrile rubber production facility represents Lanzhou Petrochemical’s first attempt at using indoor intelligent inspection robots in construction projects. We have introduced intelligent inspection robots that combine digital operation and maintenance, intelligent inspection, and unmanned operation capabilities, thereby creating the company’s first digital, unmanned substation. ”On March 25, Qian Suyu, manager of the Electrical and Instrumentation Division and deputy secretary of the Party committee, said this at the site of the 35,000 tons per year nitrile rubber production facility. According to reports, the intelligent inspection robots introduced by Lan Petrochemical incorporate various sensors such as infrared thermal cameras, visible-light cameras, and high-sensitivity microphones. These robots can take photos of the instruments on substation equipment, read the data from them, automatically record information, and issue alerts in case of any abnormalities ； It is capable of accurately distinguishing abnormal sounds from equipment noise, recording the entire process of equipment inspections, and transmitting the footage to the backend in real time ； It can accurately measure the temperature of the equipment during operation, and automatically issue alerts when potential problems such as thermal defects are detected. At the same time, the robot’s built-in system supports both fully autonomous and remotely controlled inspection modes. In fully autonomous mode, the system can independently initiate and complete inspection tasks based on pre-set parameters such as inspection content, timing, and frequency. In the special inspection mode, the operator selects the inspection items and manually initiates the inspection, while the robot carries out the inspection tasks on its own. The system uses navigation, photoelectric sensors, and barcode recognition for positioning, with a precision of ±1 millimeter. In addition, a deep learning* framework is embedded within the system, allowing the algorithms to be trained using various sample data. This offers significant advantages in carrying out large amounts of repetitive tasks, enabling continuous operation and thus improving the efficiency of inspections. For the newly built substations of this 35,000 tons per year nitrile rubber production facility, there are the 38# high-voltage substation, the 38# low-voltage substation, and the 40# low-voltage substation. Each substation covers an area of about 200 square meters. According to traditional standards, 2 operators are required for each substation; they need to conduct inspections every 4 hours in order to carry out routine inspections. With intelligent inspection robots, all inspection tasks can be completed in just 1 hour per day. “Intelligent robots conduct ‘check-ups’ on substation equipment, saving time and effort while ensuring accuracy; it is possible to monitor the operation of various devices in the substation from the control room. It is clear which devices are operating normally and which ones are malfunctioning or show discrepancies in data, which also transforms our inspection staff from ‘blue-collar workers’ to ‘white-collar workers’. ”said Zhang Jun, deputy director of Electrical Workshop 4 in that department.
