Embodiment

[0042] Such as figure 1 Shown is the structural diagram of the autonomous inspection robot inspection system of the smart power plant of the present invention, including an embedded system, a mobile module, a navigation and positioning module, a wireless charging module, a pan-tilt module, an information collection module, and a communication module.

[0043] The embedded system is used as a core controller for robot control and signal processing.

[0044] The mobile module uses a four-wheel drive mobile platform as a mobile carrier to carry each module, and the embedded control system independently controls four DC servo motors through the 485 serial port, so that the robot can move flexibly;

[0045] The navigation and positioning module includes an RFID reader, a two-dimensional laser radar, a gyroscope, an odometer, and an ultrasonic sensor, and is connected to an embedded system through a 485 serial port. Two-dimensional laser radar scans the surrounding environment to c...

Abstract

The invention discloses an intelligent power plant autonomous polling robot polling system and method. The method comprises the following steps: integrating a laser radar and a gyroscope, incrementally a raster map by using the laser radar through a SLAM algorithm; searching a middle target location with the minimum target cost estimation by using a reverse D* algorithm, thereby realizing robot dynamic path planning and positioning; reading a label through a RFID reader to acquire information needing to detect in the equipment; detecting an obstacle by using an ultrasonic sensor in the robot running process, and autonomously eluding environment obstacle in the path by combining the SLAM algorithm, thereby realizing autonomous navigation and movement in the complex power plant environment.Multiple non-contact sensors satisfy spot check demands of various sets of equipment. The polling system can automatically poll in the plant, the artificial control is unnecessary, the polling data istransmitted to a control center in real time, and the polling system can give an alarm when abnormity occurs; the polling system can replace the artificial polling, improve the polling efficiency, and improve the security of the power plant equipment.

Description

technical field [0001] The invention relates to the technical field of thermal power plant operation and maintenance, and relates to an inspection system and method for an autonomous inspection robot of a smart power plant. Background technique [0002] The main source of electricity in my country is thermal power generation. The equipment in thermal power plants is concentrated, the pipelines are widely distributed, the space is narrow, and the environment is relatively complex. In order to ensure the safe and stable operation of the power plant, regular inspections are required. At present, manual work is mostly used. The manual inspection method is costly and inefficient, and there are certain hidden dangers to the safety of the staff. With the widespread promotion of the "smart grid" concept, the construction of smart power plants has become an inevitable trend in the development of power grid technology. The use of intelligent robots to replace manual labor can effecti...
