Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to brightWhite understanding, below in conjunction with concrete diagram, further sets forth the utility model.
Hydraulic grab impacts and posture monitoring system, comprises three unit.
Referring to Fig. 1, impact and attitude transducer unit: this sensor assembly comprises grab bucket subjective posture/addVelocity sensor with grab lobe attitude/acceleration transducer; Wherein, grab bucket theme attitude/acceleration transducerBe installed on grab bucket main stress support and be rigidly connected with support (I place in figure). Grab lobe attitude/accelerationSensor is mainly installed on grabs (II place in figure) on lobe, and by fixed support with grab lobe and be rigidly connected.Each lobe of grabbing is installed a sensor, and grab bucket body considers that redundancy installs one to two sensor, bySo three-axis sensor, therefore installation of sensors direction does not affect, can carry out software setting; Mounting meansFor bolt is rigidly connected.
Data acquisition and monitoring unit: this unit is mainly by data acquisition module, control module and communication mouldPiece composition. Wherein, data acquisition module passes through data wire pick-up transducers parameter in the time of work. Control mouldThe main function of piece is that the data to gathering contrast with the each sensor numerical value allowable being recorded in registerAnd analyze, when having sensor parameters under the abnormal conditions such as transfinite, this module by communication module by differentRegular data is uploaded to on-the-spot display terminal; Occur that at important work running parameter the abnormal or scene of accepting showsWhen halt instruction that terminal is uploaded, this system will initiatively be cut off the control circuit of hydraulic valve block, thereby realExisting system tape jam is stopped using. Until completion system keeps in repair and restarts. The main function of communication module is for logicalCrossing Wireless/wired communication system is connected with on-the-spot display terminal.
Described display terminal and comparing unit: this unit comprise communication module, control module, display module,GPRS module etc. This system communication module connects by wire communication pattern and electronics Anti-scrape label read moduleConnect, receive the Anti-scrape label identification code that electronics Anti-scrape label read module reads.
