AI Technical Summary

Problems solved by technology

Cylinders cannot be monitored during the normal production process, and most of the cylinder failures are concentrated in cylinder air leakage, cylinder operation, cylinder sticking, etc., but now it is impossible to perform accurate preventive maintenance on these cylinder failures, and it is impossible to carry out trend management on the operation status of the cylinders

no. 1 example ,

[0049] Such as figure 2 As shown, the present invention provides a first embodiment of a cylinder operation failure early warning method, including the following steps:

[0050] 1) Calibrate the standard time required for the cylinder piston stroke to complete a cycle;

[0051] 2) Collect the actual time required for the cylinder piston stroke to complete a cycle;

[0052] 3) Comparing the standard time with the actual time, if the actual time is equal to the standard time, it is judged that the cylinder has no operation failure, and if the actual time is greater than the standard time, it is judged that the cylinder is running, and an operation failure warning is issued.

no. 2 example ,

[0053] Such as image 3 As shown, the present invention provides a second embodiment of a cylinder operation failure early warning method, including the following steps:

[0054] 1) Calibrate the standard time required for the cylinder piston stroke to complete a cycle;

[0055] 2) Collect the actual time required for the cylinder piston stroke to complete a cycle;

[0056] 3) Comparing the standard time with the actual time, if the actual time is equal to the standard time, it is judged that the cylinder has no operation failure; if the actual time is greater than the standard time and the actual time is greater than the warning threshold, it is determined that the cylinder has an operation failure , to issue an early warning of operational failure.

Abstract

The invention discloses a cylinder operation fault early warning system which comprises a data acquisition unit and a data analysis unit. The data acquisition unit comprises a first trigger device, a second trigger device and a data acquisition module, and the data analysis unit comprises a data analysis module and a man-machine interaction module; the first trigger device is arranged at an upper dead center of a cylinder piston; the second trigger device is arranged at a lower dead center of the cylinder piston; the first trigger device and the second trigger device send triggering signals to the data acquisition module, and the data acquisition module acquires preset data according to the triggering signals; the preset data of the data acquisition module is sent to the data analysis unit; and the data analysis module receives the preset data and judges whether to send an early warning signal or not according to a preset judgment rule, and the man-machine interaction module displays early warning information on a man-machine interaction interface according to the early warning signal. The invention further discloses a cylinder operation fault early warning method.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a cylinder operation failure early warning system. The invention also relates to a method for early warning of cylinder operation failure. Background technique [0002] The cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. It is a pneumatic actuator that converts the pressure energy of compressed gas into mechanical energy in pneumatic transmission. From the traditional point of view, cylinders and electric actuators have always been considered as automation products belonging to two completely different fields. However, in recent years, with the continuous improvement of electrification, electric actuators have gradually immersed in the field of pneumatics. There are both competing and complementary applications. [0003] The cylinder can work reliably under harsh conditions, and is easy to operate, basically maintena...
