Application of industrial-grade operation and maintenance robots in the field of electric power

An industrial robot is a multi-joint manipulator or a multi-degree-of-freedom machine device oriented to the industrial field. It can automatically perform work and is a machine that realizes various functions by its own power and control capabilities. It can accept human command or run according to pre-programmed procedures. Modern industrial robots can also act according to the principles formulated by artificial intelligence technology.

1. Industrial robot features:

(1) Programmable. The further development of production automation is flexible start-up. Industrial robots can be reprogrammed as the needs of their working environment change, so it can play a good role in the flexible manufacturing process of small batches and multiple varieties with balanced and high efficiency, which is an important part of the flexible manufacturing system.

(2) Anthropomorphic. Industrial robots have parts similar to human walking, waist turning, big arms, forearms, wrists, and claws on the mechanical structure, and a computer on the control. In addition, intelligent industrial robots also have many human-like "biosensors", such as skin-type contact sensors, force sensors, load sensors, vision sensors, acoustic sensors, and language functions.

(3) Versatility. In addition to the specially designed and dedicated industrial robots, general industrial robots have good versatility when performing different tasks. For example, changing the end-of-hand manipulators (claws, tools, etc.) of industrial robots can perform different tasks.

(4) The disciplines involved in industrial machine technology are quite extensive, and can be summarized as a combination of mechanics and microelectronics-mechatronics technology. The third generation of intelligent robots not only has various sensors for acquiring external environment information, but also artificial intelligence such as memory ability, language understanding ability, image recognition ability, reasoning and judgment ability. These are the applications of microelectronic technology, especially computer technology The applications are closely related. Therefore, the development of robotics will inevitably lead to the development of other technologies. The development and application level of robotics can also verify the development level of a country's science and technology and industrial technology.

Second, the industrial robot technology principle:

(1) Open and modular control system architecture: adopts distributed CPU computer structure, which is divided into robot controller (RC), motion controller (MC), photoelectric isolation I / O control board, sensor processing board and programming instructions Teach box and so on. The robot controller (RC) and the programming teaching box communicate via serial / CAN bus. The main computer of the robot controller (RC) completes the robot's motion planning, interpolation and position servo, as well as the main control logic, digital I / O, sensor processing and other functions, and the programming teaching box completes the information display and key input.

(2) Modular and hierarchical controller software system: The software system is built on the open source real-time multi-tasking operating system Linux, and adopts a layered and modular structure design to achieve the openness of the software system. The entire controller software system is divided into three levels: the hardware driver layer, the core layer, and the application layer. The three levels respectively face different functional requirements and correspond to different levels of development. Each level in the system is composed of several modules with opposite functions. These functional modules cooperate with each other to realize the functions provided by this level.

(3) Robot fault diagnosis and safety maintenance technology: It is the key technology to ensure the safety of robots by diagnosing robot failures and performing corresponding maintenance through various information.

(4) Networked robot controller technology: The current application engineering of robots has evolved from a single robot workstation to a robot production line, and the networking technology of robot controllers has become increasingly important. The controller has networking functions of serial port, field bus and Ethernet. It can be used for communication between the robot controller and the robot controller with the host computer, which is convenient for monitoring, diagnosing and managing the robot production line.

Application of industrial robots:

Typical applications for industrial robots include welding, painting, assembly, collection and placement (such as packaging, palletizing, and SMT), product inspection and testing, etc .; all tasks are completed with efficiency, durability, speed, and accuracy.

Industrial robots can replace increasingly expensive labor, while improving work efficiency and product quality. The Energy 13th Five-Year Plan proposes to actively promote the development of "Internet +" smart energy. Operation and maintenance robots are used in nuclear energy, wind power, electric power, petrochemical, water conservancy, and photovoltaic energy fields for full-life management.
