Problems solved by technology

[0003] However, in the actual operation process, the execution of control instructions often produces many unexpected results that affect the control equipment and the controlled equipment: However, after several execution cycles after the upper computer receives the correct response command fed back by the servo machine, the servo machine may fail due to some reasons, such as interference, power supply or load.
At this time, the enable command cannot be resent, and it is not clear whether the fault is caused by the control command or other commands
Therefore, the prior art has the technical problem that the reliability of equipment work is not high

Abstract

The invention discloses a fault processing method and device for communication equipment, and the method comprises the steps: sending a control instruction to controlled equipment; reading an execution response instruction of the controlled equipment, a corresponding running status flag bit, a fault status flag bit and the like as an execution result after control equipment sends the control instruction; judging whether an execution result is normal or not; judging whether the fault state of the controlled equipment can be read in n execution cycles or not if the execution result is normal; processing the fault if the execution result is abnormal, or the fault state of the controlled equipment can be read in n execution cycles after the control equipment sends the control instruction. By applying the embodiments of the present invention, the method can improve the reliability of the entire system including the control equipment and the controlled equipment.

Description

technical field [0001] The present invention relates to a fault detection method and device, and more particularly to a fault handling method and device between communication devices. Background technique [0002] At present, after the control device (host computer) sends control instructions to the controlled device, it pays attention to the execution result of the feedback and the fault status of the controlled device. Normally, the control device sends a control command to the controlled device when there is no fault in the controlled device, and then judges whether it has received a normal response command fed back by the controlled device. After the controlled device normally responds to the command, the controlling device believes that the controlled device has correctly executed the control command, and thus enters the sending process of the next control command. If the control device does not receive a normal response command, it is judged whether the controlled dev...
