Robot teaching box with bus communication function and control method thereof

Abstract

The invention discloses a robot teaching box with a bus communication function and a control method thereof. The teaching box comprises a central processing unit as well as a display screen, a control panel, a storage, a welding machine interface and a commutation interface which are connected with the central processing unit respectively, wherein the communication interface is connected with a robot controller at the lower layer. The robot teaching box is characterized by also comprising a touch screen connected with the central processing unit; the communication interface is based on an NRP (negotiation and resource reservation protocol) communication protocol; the message structure of the NRP communication protocol consists of a message header and field domains, wherein the message header comprises message information, an information code, message length and a bitmap, and the message information comprises a command index, a request code or respond code mark and the number of the field domains. Compared with the traditional teaching box, the teaching box provided by the invention can realize remote operation of a robot and improves the safety of operators; due to the adoption of the NRP communication protocol for data interaction, the loss rate of data is reduced to the minimum and the anti-interference performance of a system is enhanced.

Description

technical field [0001] The invention relates to the field of industrial robot control, in particular to a teaching box for industrial robot programming and control and a control method thereof. Background technique [0002] With the continuous improvement of the automation level of industrial enterprises in our country, the market for robot automation lines will also become larger and larger, and will gradually become the main method of automated production lines, thus putting forward higher requirements for the safe control and production of robots, and monitoring The loss of data and the interference of the controller on site will lead to unsafe production. At present, none of the existing teaching boxes can be remotely operated away from the robot body, which is extremely unfavorable to the safety of operators, and most manufacturers do not have touch screen functions, so teaching programming is not convenient. For this reason, designing a safe, reliable, and easy-to-man...
