Problems solved by technology

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 work efficiency and the user experience is very bad

Example Embodiment

[0028] Embodiment 1, a method to prevent the collapse of the teach pendant system.

[0029] As attached Figure 1 to 4 As shown, the method for preventing the collapse of the teach pendant system of this embodiment includes the following steps:

[0030] S1: Start the initialization of logic process 1, and query the initialization status of logic process 2 which is exactly the same as logic process 1;

[0031] S2: According to whether the logic process 2 is initialized, the logic process 1 or the logic process 2 is set as the main logic process, and the other process is set as the backup logic process. The main logic process interacts with the interface process, the main logic process and the backup logic process. All connected to the controller;

[0032] S3: The main logic process and the backup logic process synchronize data in a certain period of time. When the backup logic process acquires the failure of the main logic process, the backup logic process switches itself to become th...

Example Embodiment

[0040] Embodiment 2, a computer-readable storage medium.

[0041] This embodiment provides a computer-readable storage medium, which implements the method for preventing the crash of the teach pendant system described in Embodiment 1 when the computer program is called by a processor.

Example Embodiment

[0042] Embodiment 3, a teaching pendant.

[0043] This embodiment provides a teach pendant, including a processor and a memory, the memory is used to store a computer program, and when the computer program is called by the processor, the system can prevent the teach pendant from crashing in the first embodiment. Methods.

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. ...
