How should non-standard automation equipment design fault solutions

Non-standard automation equipment is customized and produced according to the individual needs of enterprises, and belongs to non-standard products. How to design and solve the failure of non-standard automation equipment? Next, Shenzhen Jiuke non-standard automation manufacturers will introduce to you.

 From the perspective of the reasons for the occurrence of defects, non-standard automation equipment can be divided into hard defects and soft defects. Hard defects mainly refer to the components, integrated circuit internal leads, lines, printed circuit board jumpers, etc. that cause defects. Soft defects mainly refer to changes in the internal logic state of surface equipment and plans related to system software and application software. Some shortcomings are both hard and soft, such as communication shortcomings.

The shortcomings of non-standard automation equipment can also be divided into static shortcomings and dynamic shortcomings. The static faults are those with a stable error output for a given input, and the faults are persistent faults with excellent repeatability. Dynamic faults are those that occur randomly or intermittently when the signal changes. The former is easier to investigate, detect, study and clean up than the latter.

The solutions to important failures of automation equipment are as follows:

(1) Alarm. According to the actual needs of the automation equipment system, the user can specify that an alarm will be automatically issued when certain events occur or when a protection action occurs. For example, an alarm can be set in the following situations: sudden change in switching value (such as protection tripping action); circuit breaker position dislocation; simulation The amount exceeds the set value; the transformer protection action (such as gas, temperature). The limit value of analog quantity can be modified online. Each alarm has time, alarm information and confirmation status display.

(2) Events. All action events in the automation equipment system, such as automatic protection action, operation of circuit breaker, isolating switch, grounding switch, etc. All can be automatically printed and stored in the system hard disk memory, each event has time and related information text description, and can automatically print records.

(3) The protection functions and setting values that can be modified by the mainframe of the automation equipment system or the centralized control cabinet. All remote modification functions are online, and the fixed value after modification will be directly sent back to the corresponding storage. Operation lock. The system can set the blocking function for all operation objects to prevent the operator from misoperation.
