Substation robots have been widely used with the increase of power transmission. Its intelligent system can achieve unattended operation for 24 hours, but it can still work. The inspection data under high pressure environment is still accurate, and the inspection automation jobs.
In recent years, with the continuous increase of power systems and capacitors, ensuring the safe and stable operation of power systems and power equipment has become an important part of the management and development of the power industry. However, during the operation of the power system, the substation, as the core of the power system operation, mainly plays the role of power supply. However, due to the continuous improvement of substation automation technology, unattended or unattended duty has become a key development content, and the safety of systems and equipment as a key consideration, the traditional inspection mode can no longer meet the needs of modern substations. Based on this, the working robot will gradually become intelligent, and it has become the focus of the development of substation inspection tasks in China.
The substation robot adopts a hierarchical structure, including an inspection warehouse system and a monitoring management system. The technician first launches the patrol robot by issuing a patrol task, receives all the data collected by the background monitoring management center during the patrol, and displays and processes it. In this regard, the background mainly finds and corrects equipment defects through pattern recognition and image processing technology, and issues equipment maintenance commands again. The second is the basic system of inspections. The system refers to the patrol robot itself. The functions of mutual communication and data transmission are realized through wireless communication and monitoring equipment. The robot body also includes servo control, information acquisition, visual navigation, positioning, and self-testing maintenance system modules.
Orbit is the navigation method of the substation robot, and it determines the motion range of the inspection robot in the substation automation operation. The following points should be considered in the design: ensure the full coverage of the primary equipment of the substation, and choose the road near the equipment. For station trunk roads and cable shelters, the correct track should be selected to meet robot operation. For concrete pouring roads and asphalt pavements, during the operation of the robot, a suitable construction method must be selected to ensure the navigation stability of the robot track. In order to ensure the stability of the robot, the track should maintain a certain safety distance from the low-resistance electromagnetic equipment to ensure that the electromagnetic interference of the equipment will not affect the robot's automatic cruise.
The pick-up device of the substation robot can collect the noise generated during the operation of the equipment in the substation and transmit it to the monitoring background. By analyzing the noise, you can understand the working status of each component, so as to ensure the normal operation of each component. In addition, the intelligent detection robot's infrared detection system can detect and monitor the temperature of transformers, transformers, switches, knife gates, guide wires, wiring palms and other equipment in real time. By comparing the temperature rise of the same device and analyzing the historical change trend, the highest temperature region and temperature value in the image can be displayed to detect the temperature value. The specific cause of the heat that may cause the area should be judged whether it is electric heating or voltage heating, and timely alarms should be given to employees to pay attention to relevant issues and solve them in a targeted manner.
The substation robot improves the efficiency of business processing, reduces the error rate of manual recording, and improves the efficiency and quality of inspections. At the same time, it helps the inspectors to work efficiently. Power companies can grasp all the information in a timely manner through mobile email, mobile meetings, etc., to make faster and better decisions and effective management, provide more convenient services for enterprises and individuals, and improve the level of power services. The user as a whole.
