Method for preventing demonstrator system from collapsing, computer readable storage medium and demonstrator

Abstract

The invention provides a method for preventing a demonstrator system from collapsing. An interface process and a logic process are separately designed, so that software development efficiency can be improved, subsequent testing and maintenance are more convenient, and maintenance cost is reduced accordingly; and availability and stability of demonstrator software can be effectively improved by adopting the main logic process and the standby logic process, and the phenomenon that the whole system is shut down due to operation faults of the demonstrator can be effectively avoided no matter whether an operator exists beside or not when a machine works. According to the method, the heartbeat mode is kept between the interface process and the logic process, the crashed interface can obtain datafrom the logic process after being initialized and return to the state before crashing under the non-stop condition, and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the field of industrial robot control, in particular to a method for preventing the system crash of a teaching pendant, a computer-readable storage medium and a teaching pendant. Background technique [0002] With the rapid development of automation level, the demand for industrial robots is increasing in today's society. As a bridge for the interaction between operators and robots, the teach pendant greatly affects the operator's experience. During the operation, occasionally the teaching pendant interface crashes and the software stops working due to factors such as frequent operations and unstable software operation. At this time, the operator usually needs to power off and restart the entire controller, which not only increases the The debugging time of the designer, and if the operator is not on site, the working state cannot be restored immediately, which reduces the work efficiency and the user experience is very bad. ...

[0003] Patent No. 201810419413.1 discloses a 1+N redundancy mechanism design method for SCADA systems, but this method uses the service process object to view its own "server running list" configuration items and then reports to the local real-time database management process Reports are then filled into the wait list, resulting in increased memory requirements and more complex designs

[0004] Patent No. 2013102195353 discloses a multi-process protection system and its implementation method. It uses three additional processes (management process, backup management process, and daemon process) to monitor the running status of the management application process. The management module replaces the management process module, which uses many processes and requires a larger operating space, and is not suitable for lightweight teach pendant equipment
