The invention discloses an SCATS coil data-based traffic state online quantitative evaluation and prediction method, which relates to the traffic state online quantitative evaluation and prediction method in the technical field of traffic. The SCATS coil data-based traffic state online quantitative evaluation and prediction method comprises the following steps: acquiring traffic parameters and uploading the traffic parameters to a traffic information centre by an SCATS coil; performing quality evaluation and control on actually-measured data by a computer; performing traffic parameter virtualtime sequence construction on the actually-measured data subjected to the quality evaluation and control; performing the quality evaluation and control on virtual time sequence data; performing traffic congestion automatic identification on the virtual time sequence data of the parameters; performing short multi-stage prediction on the virtual time sequence data of the traffic parameters; and on the basis of the short multi-stage prediction on the virtual time sequence time of the traffic parameters, performing traffic congestion spreading range prediction and duration prediction and issuing prediction results to a traffic administrative department to provide more forcible basis for decision making for the traffic administrative department.

A movable net for intercepting floating objects in the ocean and its use method. The main body is a rectangular net made of polymer materials; the upper and lower nets are respectively equipped with floating balls and sinkers to support upward and downward Tightly intercept the dredging net to maintain a relatively stable rectangular shape; there is an aeration tube on the lower net or at a depth of 10 meters, and the aeration is performed by the side net net inflatable tube; there are two large anchors on the lower net, Through the adjustment of the position of the large anchor anchor, the interception and dredging net can be arranged arbitrarily in the ocean, and the best interception and dredging effect can be obtained or the interception and dredging net layout angle, length, and distance from the sensitive protection target can be obtained according to the actual production needs. Changes in the direction of ocean currents are adjusted and optimized at any time. The present invention can be used in series with multiple networks for artificial or natural interception and dredging or interception and capture of marine floating objects, and can be adjusted and optimized at any time according to the actual situation to maintain the optimal interception and dredging effect, and has a good application prospect.

The invention discloses application of cellulose in an occasion of graphite grinding particles, and in particular relates to the technical field of grinding oil recovery and filtration. Specifically, the cellulose is used as a filter aid during recovery and filtration of graphite grinding oil for grinding, the cellulose controls the content of fine graphite particles in the grinding oil, the usage period of the grinding oil is prolonged, the reasonable additive amount is increased, the usage cost of equipment and the environment pollution are reduced, and the production efficiency is improved.

The present disclosure relates to a vehicle control method, system, device and computer-readable storage medium, and relates to the technical field of the Internet of Things. The method includes: obtaining the scene image of the congested area and the identity information of each vehicle in the congested area; according to the scene image, matching the identity of each target vehicle identified from the scene image with the corresponding identity information; obtaining the status of each target vehicle information; according to the identity matching result and status information, generate a control instruction so as to control each target vehicle to leave the congested area. The technical proposal of the present disclosure can improve the dredging effect.
