The invention discloses a cutting fluid circulation system in a stainless steel processing workshop, comprising a processing equipment group, a circulation tank and a filtering system. The processing equipment group and the filtering system are communicated through a first integrated tank, and the first integrated tank passes through The conveying pipeline is communicated with a primary filtering channel, a secondary filtering channel is arranged below the primary filtering channel, a mixing chamber is provided below the secondary filtering channel, and a vortex stirrer is arranged in the mixing chamber, and the mixing A solvent box and a preparation box are fixedly installed on the outer side wall of the cavity, an injector is installed at the connection between the solvent box and the preparation box and the preparation cavity, and both ends of the filter system are provided with residue recovery bins. In the present invention, the cutting fluid in the workshop is formed into a circulating circuit through the pressurized pump group, and the used cutting fluid is filtered, separated, transported and allocated in the circuit. After the processed cutting fluid meets the conditions, the Transfer to the processing end for matching processing.

The invention discloses a mobile terminal dataflow saving method includes the following steps: (S1) when a screen of a terminal is shut down, detecting whether a data network of the mobile terminal is connected or not, skipping to (S2) if the network is connected, and finishing detection if the network is not connected, (S2) starting a timer, counting down according to preset time through the timer, (S3) carrying out data network connection warning when the counting down of the timer reaches the set time, popping up a dialog box to prompt whether to close connection of the data network, skipping to (S4) if choosing to close the data network in the dialog box, otherwise skipping to (S5), (S4) closing the connection of the data network, and (5) maintaining a connection state of the data network. The method has the advantages of detecting the connection of the data network after the mobile terminal shuts down the screen, reminding a user when the preset time is finished so that the user can close the connection of the data network after being reminded, and therefore avoiding the phenomena that flow is wasted because the user forgets to close the connection of the data network.

The present invention relates to the technical field of intelligent networked vehicles, and aims to provide a method for arranging test scenes of intelligent networked vehicles in a closed test field. The closed test field contains several test scenes for vehicle training, wherein the arrangement of test scenes in the closed test field The method includes the following steps: divide a plurality of typical scenarios M, and specifically refine a plurality of scenarios N to be planned from the typical scenarios M, wherein, the typical scenarios also contain multiple characteristics to meet the basic test needs; The scene M is associated with each scene N to be planned, and the score is calculated; according to the final score, the typical scene with high correlation and the scene to be planned are divided into the same functional area, and the closed test field is obtained through the divided functional area , which is conducive to the organization and implementation of different test scenarios, reduces the construction time of different types of scenarios, reduces construction costs, avoids repeated layout of facilities and equipment, and improves the operation and management efficiency of test field management units.

The present application provides a charging control method, device, computer equipment and its storage medium; the method is applied in a charging field system, and the system includes a server end, a charging pile connected to the server end, and an AVP system; the method is performed by the server Terminal execution, including: receiving the charging request sent by the vehicle-mounted terminal of the target vehicle, and selecting the target charging pile in response to the charging request; sending a parking command to the AVP system, taking over the target vehicle through the AVP system, and automatically driving the target vehicle to the target charging point The charging position of the charging pile; after the target vehicle enters the charging position of the target charging pile, an instruction to open the charging port cover is issued to the vehicle terminal; a charging instruction is sent to the target charging pile, and the gun insertion robot of the target charging pile is controlled to insert the charging gun into the target vehicle Charge according to the opened charging port. This technical solution can scientifically automate the allocation and use of charging piles, without the need for the owner to complete the charging process, improving charging efficiency.

The invention discloses an automatic drawing method for land-sea ecotone meteorological isolines. The automatic drawing method includes steps of 1) reading data from multi-dimensional marine meteorological data, acquiring land-sea boundary data, and isolating marine regional data by overlay analysis; 2) setting a threshold value of judging a noisy point, judging each pixel, and if a pixel is the noisy point, correcting the pixel to acquire an effective numerical range of the marine region; 3) dividing the whole region according to the effective numerical range of the marine region; 4) respectively constructing interval tables of the marine region and other regions, and setting intervals with uneven densities on each region; 5) combining the intervals of the marine region and other regions; and 6) reading batch data through MATLAB (matrix laboratory ), and applying the intervals to MATLAB isolines drawing instructions to achieve the automatic drawing. By the automatic drawing method, the isolines effectively highlight changes of marine regional factors, show meteorological factors of a land region at the same time and can be applied to the fields, such as drawing a thematic map of the land-sea ecotone meteorology.
