Study On The Autocontrol System Of Crane Task Dependabilit Test

At first, the article remarks on the means and actualities of operation reliability of type test and many examinations of Truck crane in our country. With new products is produced fast, period is shorten, manpower and material resources is increased .Both test institutions and enterprises are eager to have a operation reliability test autocontrol device according with related standard and criterion, This equipment has reliable properties, easy to operated, can reduce labor intensity and raise labor productivity. Compared with developed countries, the technology level and automation of construction machinery, on the whole, are lower. With relation to this, the test means to new products are even poorer. This kind of autocontrol equipment has not appeared in our country.The paper makes full use of computer control in the field of operation reliability test from pragmatic view. According to concerned standards, the paper analyses feasibility of several control forms, establishes the control forms of off-line control of computer combined with limit radius principle. And, advantage and shortage of several kinds of implemental mechanism are contrasted and analyzed in the paper. Overall design scheme, the composition of control system, hardware construction and software control flow are given in detail., design philosophy of hardware and software is established . The paper bases control algorithm of operator and control program diagram on thorough investigation into Truck crane operation reliability action flow, which makes sure of accurate and effective control over handle and accelerograph and achieves test process automatization. This application research have important significance for autodetec of test parameter , higher operation efficiency, personnel security. What's more, security and anti-disturbance of control system are considered sufficiently in the paper, control system will be extended easily also.Finally, the paper gives an explanation of the results of indoor simulation run and put forward the recommendations for system improvement.
