Description
Technical field
The present invention relates to a kind of sensing device of electronic technology field, specifically, is a kind of sensing device of automobile dynamically weighing.
Background technology
Quite serious in China's truck overload and illegal repacking loading phenomenon, cause most highways and bridge to be in the overburden running status for a long time, not only have a strong impact on the serviceable life of highway and bridge, but also cause the frequent accidents in the vehicle ' process to take place, particularly some highway can't bear the heavy load especially, very dangerous.To thoroughly avoid and prevent the generation and the existence of this type of phenomenon, outside-the-system except strengthening improving the traffic legal construction and setting up scientific management, more crucial is also will have the modern technological means of a cover assist to solve with raising monitoring automation technical merit.
Find by prior art documents, [auto technology] 2002.6, article: based on the automobile overload identification of neural network, author: Zhang Youliang, Yuan Mingxin, Chu Hao, two load-bearing plates are installed in employing on the road surface, expressway access, impact to the load-bearing plate when automobile passes through this road surface under certain speed is exported two signals by two sensors, import computing machine after amplification of signal process and the analog to digital conversion, two signals are carried out one 8 dimensional feature vector of feature extraction stroke, utilize under certain speed of a motor vehicle the funtcional relationship between the characteristic parameter and axle load to adopt neural network algorithm to calculate to obtain the automobile axle load again, relatively obtain identification that whether tested automobile is overloaded through axle load and the maximum permission of tested automobile regulation axle load at last.The carload sensing technology that this system adopted is on highway inlet road surface two load-bearing plates to be installed, and exports two load-bearing information by the impact to the load-bearing plate by the sensor that is attached thereto.This load-bearing sensing mode is feasible technically, but, because the pressure spot that requires automobile front and back wheel by above-mentioned inlet road surface the time to depart from two load-bearing plates in actual applications must not exceed certain limit, it is too harsh that this just certainly will accept testing conditions to tested vehicle, also can reduce vehicle pass-through speed and work efficiency simultaneously.
Through further retrieval discovery, the invention of Su Qingzu " weighing instrument in the portable running-vehicle ", number of patent application: 02138337.5; Granted publication number: CN1152238 relates to the mechanical field of weighing, and can realize real-time measurement and evaluation to automobile load.Its concrete technology is that the rubber pressure oil pipe is placed the road surface, and the oil pipe end is equipped with manual pump and pressure transducer, through pressure transducer pressure signal is transferred to the signal Processing instrument.Adopt or form an angle layout or on road surface be ladder-like arranged vertical according to different needs, and multiple-tubing string such as arranges simultaneously at various ways placement oil pipe with vehicle running route with pressure oil pipe.This technology is except under static state, low speed and high speed measured automobiles wheel load, axle load and the gross mass, also measuring speed, the wheelbase of automobile.The validity that whole technique is weighed to automobile is worth certainly, but the technological deficiency of Cun Zaiing wherein: 1, when the automobile of different dead weight capacity pushes the pressure oil pipe of this invention technology, because the extruding contact area is not constant, and have great randomness, therefore be difficult to set up the accurate expression between the quality (or weight) of force value that sensing obtains and tested wheel shaft, in other words, be difficult between tested weight and the pressure accurately determine; Need when 2, arranging pressure oil pipe again " adopt or form an angle layout or on road surface be ladder-like arranged vertical according to different needs with vehicle running route with pressure oil pipe; and multiple-tubing string such as arranges simultaneously at various ways placement oil pipe ", this makes this technology add the service condition of a strictness in actual applications, inevitably vehicle pushes the vibrations that cause and can destroy original any accurate position arrangement at any time, therefore can make this invention technology lose its basic practical value.
