Problems solved by technology

For example, storage devices such as serial memory chips or CF cards cannot guarantee high-speed real-time storage.
In the existing robot system, the parallel bus structure is generally used, which makes the wiring of the robot control cabinet relatively complicated, and it is not easy to expand and apply to the robot production line
In some occasions with special requirements, the electronic control part needs to be redesigned. In addition, the complicated parallel bus wiring makes the system vulnerable to external interference.

Abstract

The invention discloses an integral device for combining data storing and on-site bus communication. The device utilizes a logic control unit to be a core, which comprises a data storage unit connected with the device, an on-site bus communication unit, and an interface unit of an external control device. The invention realizes high-speed real-time data storage and high-speed serial on-site bus communication of integration, the control unit is reasonably designed, the production cost of the system is little, and the anti-interference ability is strong, which is easy to extend and be applied on a robot production line.

Description

technical field [0001] The invention relates to industrial robot controller technology, in particular to an integrated device based on PC104 bus data storage and field bus communication. As a device that provides high-speed real-time data storage and expands the field bus communication interface, it is used in robot systems and robot production lines. Background technique [0002] The storage of parameters in the existing robot controller needs to be saved before the system is powered off. If an abnormal power failure occurs, the current parameters will be lost, or the battery is used to maintain data storage in the system, requiring frequent battery replacement and other maintenance. For example, storage devices such as serial memory chips or CF cards cannot guarantee high-speed real-time storage. In the existing robot system, the parallel bus structure is commonly used, which makes the wiring of the robot control cabinet relatively complicated, and it is not easy to expan...
