Description
Technical field:
The present invention relates to hydraulic cylinder works condition intelligent detection technique field, relate in particular to a kind of intelligent hydraulic cylinder system.
Background technique:
Many engineering mechanical devices such as excavator, hoist, loader etc., comprise other special vehicles such as fire-fighting truck, and the various motions of its equipment are wherein adopted hydraulic cylinder mechanism in a large number to adopt hydraulic transmission to drive as main.In the system of oil hydraulic cylinder executive component, hydraulic fault is embodied a concentrated reflection of out by executive components such as oil hydraulic cylinders usually.When using these equipment, usually find that the oil hydraulic cylinder action is ineffective, oil hydraulic cylinder is owed speed, produce the fault such as creep, cylinder barrel distortion or beam hanger are crooked, in addition detonation appears, the equipment unstability is collapsed, and leads to the serious consequence such as major accident.Tracing it to its cause, mostly is can not adapt to the normal running requirement because of analysis of hydraulic oil overheat, oil hydraulic cylinder internal pressure deficiency, working condition, and the guidance tape excessive wear causes heat accumulation, and serious overload causes excessively high causing of in-cylinder pressure.Equipment failure not only affects the normal operation in the work progress, brings very large impact for construction quality and project progress, also causes security incident, works the mischief to the people life property safety.
Equipment is intelligent, and by adopting Modern Transducer Technology, digital communication and network technique, computer technology, the collection of information, processing, transmission, demonstration and highly integrated sharing adopt modern control device to realize device security, reliable, efficient operation.
Intelligent hydraulic cylinder system can be in equipment work, in real time hydraulic cylinder works state analysis and demonstration, and report to the police, guarantee that hydraulic equipment runs well, and improves the reliability of whole equipment, Security.The engineering machinery working condition is complicated, and exposing to the weather drenches with rain, and pollution, dust etc., and the whole equipment of hydraulic system and engineering machinery is all caused adverse effect, and the oil hydraulic cylinder long-term work is in such environment, and fault is unavoidable.Therefore, in order to obtain the safety under the implementing precondition in the safeguard work function and to improve oil hydraulic cylinder working life, the user needs to understand in real time the running parameter of oil hydraulic cylinder, such as cylinder barrel distortion, the wearing and tearing of moving element and the working stroke of the temperature rise between friction zone, oil liquid temperature, pressure and oil hydraulic cylinder, etc.
At present, intelligentized research is in blank substantially to oil hydraulic cylinder, although the intelligent hydraulic cylinder is had some understanding, how to define, how to use not clearly concept.Traditionally, adopt pointer instrument to carry out the detection of single parameter.Even in today of microelectronic technology development, also less parameter measurement is carried out in basic only consideration, and the parameter that detects is for online Real Time Monitoring, not from the system intergration, intelligent control, and go to consider from the height of life cycle, more do not form the concept of intelligent hydraulic cylinder.
Summary of the invention:
The object of the present invention is to provide a kind of intelligent hydraulic cylinder system, the problem that can not realize intelligent real time and on line monitoring, can not comprehensively monitor the hydraulic cylinder works state to solve the oil hydraulic cylinder that uses on the present engineering machinery.By various perception and communication and treatment technology, realize visual, digitizing and intelligent monitoring to each oil hydraulic cylinder relevant parameter on the engineering machinery.
For achieving the above object, the technical solution used in the present invention is:
