In recent years the view of Jinggangshan is enchanting by its unique mountainous landscape and revolutionary cradle, which offers many attractions for tourists at home and abroad. Develop continuously along with the tourism industry, the blind development of land resources in the drive for economic interests has been leading to serious degradation of its land ecosystem mountainous and causing serious...
CNC system based on Siemens AG SINUMERIK820-core used for processing control of MKS1632 high-speed cylindrical grinding machine is designed. The mechanism of high speed spindle is that the motor and spindle are combined as one body, rapid feedrate is realized by steeplead ball screw and increasing feed servo motor rotation speed, the wear particles of wheel are mainly of cubic Boron Nitride and diamonds,...
We used to crank connecting shaft neck in the center of the neck as the origin of work piece coordinate system. Through the offset of the work piece coordinate, we made use of the method of the coordinate value in keeping with the real coordinate diameter or the relative location value of the work piece center. We designed a kind of crankshaft NC dresser which consists of the Siemens servo semi-closed...
In this paper, we propose an on-line detective technique of river sediment measurement based on image processing. The first step of the detective technique is to get the river sediment by sinking the underwater camera equipment into the designated section using the existing hydrology cableway in river hydrological stations. After the workstation computer sends control command to the underwater camera,...
We design an embedded electric meter based on Bluetooth data acquisition system in view of the complicated cables and accident potential in the process of data acquisition of electric meter. Combined wireless Bluetooth communication technology with data acquisition system, we build wireless data acquisition system based on ARM processor LPC2142 and Bluetooth chip Rok101008 in the embedded electric...
An improved fuzzy interpolation algorithm for two-pipe water samples collected bistable valve control system has been proposed. The control system mainly consists of 32-bit embedded RISC microprocessor core, which using the improved fuzzy interpolation algorithm bistable twin-tube water samples acquisition valve. The practical application of the results have solved many key technology, such as the...
We propose the transformer substation online detection system based on Lon Works Bus which uses the intelligent neuron chip as the control core of the intelligent node. The Lon Works Bus-based system is used for real-time data acquisition, parameter calculation, equipment state analysis, fault diagnosis, high-speed information transmission of substation. We improve the anti-interference ability and...
An independent dual-core structure of river sediment image data transmission system based on DSP and ARM, it uses dual audio frequency signals to transmit, and adopts Kalman filter algorithm with prediction function, it also has improved robustness PID controller. The system compress codes through DSP system then transmit good-dealt image codes to ARM system, the ARM system would pack the compress...
According to the characteristic of river sediment image, the two-dimensional image data is transformed into one-dimensional array data from horizontal, vertical, + diagonal line, - the diagonal line four directional, by using different threshold value on the different wavelet decomposition high frequency coefficient and enhancing the processed coefficient, de-noise image is obtained after inversing...
We propose the online hydrological sediment detection system based on image process. It consists of image collection subsystem, signal transport processing subsystem, network transmission subsystem and ARM-based processing subsystem based on PXA270 processor. The system's configuration and structure is described. The system gets the image of mountain rivers flow section by using on-line technique...
In response to the complexity of the cable, the occurrence of accidents and completing the task without cables in industrial field, an embedded Bluetooth data acquisition system which was combined with Bluetooth wireless-networking communication technicalness and data acquisition technicalness, based on LPC2142 and bluethooth chip called Rok101008 is designed to reduce cable connection.The major difference...
Because of the size, position, property of the tumor organization are different, as well as in individual difference and tumor organization's change in thermotherapy process, it is very difficult to set up the mathematical model with accurate system, so it is unable to reach the ideal result to adopt traditional PID to regulate. The based on interpolation algorithm tumor thermotherapy fuzzy control...
Wind generating set online monitoring and fault diagnosis system, using CAN bus, combines by sensor system, scene gathering and processing, monitoring system, analysis and diagnosis system, network system, etc.. This system combines signal processing, artificial intelligence, communications, DSP, databases, computer networks and so on, decomposes a complete online monitor and diagnosis duty to each...
In the control system, the application of basic fuzzy controller method, steady-state quality is not very good, steady-state accuracy is not high. The main reason is the controller regulation dead zone caused by rough quantitative stepping of calculation by error E and error slewing rate Ec, and the too rough regulation formed by the stepping controller output. wind driven generator difficult to meet...
The record way of most existing water level monitors is to use the float type, cannot satisfy the request of digitized output.Therefore studied one kind of water level monitor recording instrument composed by the microprocessor, drive circuit, stepper motor, the electric conduction metal measured linc.thc volume line drum,the water level supervised gauge head. Its characteristic one is actual measure...
