Automatic stacking/reclaiming system for bulk cargo storage yard

InactiveCN104724506ASimplify hardware configurationEasy to installLoading/unloadingBulk cargoControl signal
The invention provides an automatic stacking/reclaiming system for a bulk cargo storage yard. The automatic stacking/reclaiming system comprises a stacker distributed in the storage yard and provided with a stacking cantilever, a reclaimer distributed in the storage yard and provided with a reclaiming cantilever, a first laser scanning device installed on the stacking cantilever and used for acquiring scanning data of the storage yard, a second laser scanning device installed on the reclaiming cantilever and used for acquiring the scanning data of the storage yard, a stacking positioning device and a reclaiming positioning device for acquiring GNSS positioning information, a stacker control device, a reclaimer control device, a remote stacking processing device and a remote reclaiming processing device. The stacker control device and the reclaimer control device acquire and output the GNSS positioning information, receive a stacking control signal and a reclaiming control signal, and control the stacker and the reclaimer to execute corresponding stacking/reclaiming actions according to the control signals. The remote stacking processing device and the remote reclaiming processing device receive a stacking instruction and a reclaiming instruction input by a peripheral user, acquire coordinate information of the corresponding storage yard according to the instructions, the scanning data and the GNSS positioning information, and generate stacking/reclaiming path information to serve as the stacking/reclaiming control signals to be output to the stacker control device and the reclaimer control device. The automatic stacking/reclaiming system is based on GNSS positioning, and is high in accuracy and low in cost, data can be shared, and automatic operation of the bulk cargo storage yard is achieved.

CT image iteration reconstruction method based on compressed sensing

The invention discloses a CT image iteration reconstruction method based on compressed sensing and particularly relates to a CT image reconstruction method for carrying out minimization algebra iteration (algebraic reconstruction technique, ART) of the total variation (TV) in a wavelet domain. The method mainly comprises the steps that (1) imaging parameters of a CT system and projection data collected by a scanning system are obtained; (2) the projection data are initialized, and namely, Wiener filtering noise reduction processing and wavelet sparsity conversion are carried out on the projection data; (3) algebra iteration reconstruction is carried out on the initialized projection data on the basis of minimization of the image total variation (TV), and whether the iteration result meets a convergence condition is judged, if not, the iteration reconstruction image data are used as initial values, and iteration continues to be carried out; if yes, reconstructed images are used as final output images. Compared with the traditional filtering back projection and algebra iteration CT image reconstruction technology, the method finishes reconstructing the images with the fewer projection data, the speed for reconstructing the images can be increased, the radiation dose is reduced, and the image reconstruction quality can be improved.

Method for tracking solar double-peak maximum power point

The invention discloses a method for tracking a solar double-peak maximum power point. The method comprises the following steps of: 1) performing global scanning periodically, if a global scanning time reaches a predetermined time, executing the step 2) to the step 4) in turn, and if the global scanning time does not reach the predetermined time, performing a local MPPT algorithm all the time; 2) defining initial scanning power and setting an initial step length; 3) measuring a current voltage and a current, and calculating current power, wherein the current power is equal to a product of the current and the current voltage; and 4) comparing the current power with last power, and judging power change by disturbing a duty ratio continuously to determine whether the scanning is finished so as to determine a maximum power point. The method has the advantages that: periodic global scanning is added into a common maximum power point tracing algorithm; a scanning time is shortened effectively according to series-parallel characteristics of a solar system so as to ensure the steady operation of the system and avoid that the system works at a secondary maximum power point in a double-peak phenomenon; and therefore, electric energy production is improved.

Human body three-dimensional data collecting system and method based on light coding technology

The invention provides a human body three-dimensional data collecting system and method based on the light coding technology. The human body three-dimensional data collecting system comprises a rotary disc. Supports are arranged on the periphery of the rotary disc, a whole-body scanner, a half-body scanner and a face five-sense-organ scanner are installed on the three supports respectively, data lines at the tail ends of the three scanners are connected into a computer, and a matched software tool for model collecting, fusing, repairing and strengthening is arranged in the computer. The human body three-dimensional data collecting system is simple in structure, low in cost, high in accuracy and short in scanning time, the advantages of the scanners in different types are combined, division operation is adopted, the aim is explicit, and high-accuracy human body characteristic three-dimensional models of the five sense organs of the human body face, the head outline, hair details, the whole-body surface outline and the like can be obtained; a high-accuracy human body three-dimensional model can be obtained by fusing and splicing the characteristic three-dimensional models collected through the different scanners through software, and follow-up model processing is avoided; the multiple scanners work at the same time, and the scanning time is greatly shortened.
