Embodiment Construction

[0018] figure 1 A pneumatic device is shown schematically, where in principle another fluid device, such as a hydraulic device, is also possible.

[0019] This pneumatic device comprises five subsystems 10-14, among which may be respectively actuators such as valves, cylinders, linear drives and the like, and combinations thereof. The subsystems 10 - 14 are supplied with pressure by a pressure source 15 , wherein a flow meter 17 for measuring the flow or volume flow is arranged in a common supply line 16 . The air consumption is obtained by adding or integrating the measured values ​​of the flow or volume flow or mass flow. Subsystems 11 , 12 and subsystems 13 , 14 in turn each form a system with a common feed line.

[0020] The electronic control unit 18 is used to predetermine the operation of the device and is electrically connected to the subsystems 10-14. Subsystems 10-14 receive control signals from electronic control unit 18 and pass sensor signals back thereto. Suc...

Abstract

The invention relates to a method for fault localisation and diagnosis in a fluidic installation. According to said method, the fluid consumption in at least one region of the installation is recorded, and compared with a corresponding stored reference consumption according to the operating cycle. Respectively at the time of a variation in consumption or at the end of a continuous variation in consumption, the system and / or subsystem (10-14) of the installation, in which a process influencing the fluid consumption has taken place at this point, is determined, and said system and / or subsystem (10-14) can thus be identified as faulty.

Description

technical field [0001] The invention relates to a method for fault location and diagnostics in fluid devices, especially in pneumatic devices, in which the fluid consumption of at least one area of ​​the device is measured and compared with a correspondingly stored reference consumption depending on the duty cycle. Background technique [0002] DE 19628221 C2 discloses a method of this type for determining the working position of a working device of a pneumatic device without using sensors, in particular without using position sensors. Primarily in large installations in which several processes overlap one another, the position of a working device or a position within a specific working device cannot be deduced exactly. If one of the working devices malfunctions or leaks, it is impossible to make a clear judgment and determination, and it is impossible to find out the exact abnormally functioning working device or part of the device at all.
