Control method for damping value of electronic control air spring damping apparatus with three-gear

The invention discloses a control method for the damping value of an electronic-control air suspension fork three-grade adjustable absorber, wherein, according to the simulation analysis of the ride comfort, the suspension fork dynamic deflection and the dynamic load are used as the limit condition, the genetic-algorithm optimization program is compiled, and then the influences of the sprung mass, vehicle speed, and road surface on the damping value optimization are respectively analyzed, so that the sprung mass and the vehicle speed are determined as the main factors for influencing the damping value optimization; according to the real run condition of the vehicle, the change of the sprung mass is divided into three sections: no-load to half-load, half-load to 3 / 4 full-load, and 3 / 4 full-load to full-load; during the sprung mass change of each section, the different mass and the different vehicle-speed as the influence factors are taken into the consideration; the damping value of each grade is pre-optimized by the genetic algorithm and then the damping value is memorized in the ROM of a suspension fork control system ECU; ECU makes use of the signals sent by a sensor to judge the real-time run condition so as to control the executing mechanism to make a response to select the corresponding damping value.

Machine vision-based automatic verification system for multipath hand-held digital multimeters

The invention relates to a machine vision-based automatic verification system for multipath hand-held digital multimeters. According to the technical scheme of the invention, a hand-held digital multimeter is automatically controlled to select different function range gears; according to to-de-verified items, controlling a multifunctional calibration source to output standard signals (alternating-current voltage, direct-current voltage, alternating current, direct current, resistance value and the like) to a multipath to-de-verified digital multimeter, and conveying the measurement data of the panel of the to-de-verified digital multimeter to a computer based on the image collecting, processing and recognition function at the same time. In this way, verification data can be automatically recorded, and then a verification report and a verification certificate are generated. After the verification process, a database is established and then verification records and verification data are stored over the cloud through a cloud server. Meanwhile, a verification result is generated in the form of a two-dimensional code, so that the verification result can be conveniently recorded and searched. Meanwhile, the data sharing is facilitated. Compared with the manual verification mode of a conventional digital multimeter, the working efficiency is greatly improved. Moreover, errors caused by human factors are reduced and the comprehensive quality management is conveniently realized.

Method for generating row transposed architecture based on two-dimensional fft processor

The invention discloses a method for generating a row transposed architecture based on a two-dimensional FFT processor, comprising the following characteristic: the FFT processor includes an on-chip row transposition memory for storing an image row transposition result. When the size of the row transposition result exceeds the capacity of the on-chip memory, the first 2k data of a row of the two-dimensional array after row transformation is written into the on-chip row transposition memory, the remaining data is written into the off-chip SDRAM, and k is acquired through calculation according to the row transposition result and the capacity of the on-chip row transposition memory. The on-chip memory is divided into two memories A and B used for storing the row transposition partial result and temporarily storing data read from off-chip SDRAM. When data is read from the memory A or B column by column for FFT column transposition, SDRAM is accessed in a row burst manner and data is written into the empty memory A or B alternately, and finally SDRAM is empty through repetitive ping-pong switching between the memories A and B. The row transposed architecture is capable of substantially reducing cross-line accessing frequency of SDRAM and improving two-dimensional FFT execution speed.
