The invention relates to a high-performance log record query method for an integrated circuit production line carrying system. The method includes the following steps of calling log client-sides through all modules to send log information to a log server, storing log data into a memory information list in a memory after the log server receives log data, detecting the size of a currently-connected database, regularly traversing the memory information list, separating out log information, storing the log information in the database, positioning the database according to the time range to be inquired about, inquiring about the log data in the database, and forming new log information through combination, and returning the new log information to a user interface. By means of the method, the high-performance log storage and query can be achieved, the space occupied by disks can be saved, and the data storage and query efficiency can be improved.

The invention provides a second-hand vehicle valuation method and a valuation system. The method comprises the following steps of firstly, constructing a supervised learning-based linear model for a predicted vehicle model, and carrying out linear regression training by utilizing historical transaction data of the predicted vehicle model; and then the second-hand vehicle price evaluator performs manual adjustment on the abnormal point until the linear model prediction result reaches a preset target. According to the invention, the manual adjustment system is introduced into the training process of the machine learning model, so that the generalization capability of the machine learning model can be effectively enhanced, and the prediction precision of the machine learning model is improved.

The invention discloses a link testing method and device, computer equipment and a storage medium, and the method comprises the steps: operating a to-be-tested link, inputting to-be-tested data to the to-be-tested link, the to-be-tested link comprising N modules, and N being a positive integer greater than or equal to 2; obtaining a first information set of the N modules, wherein the first information set comprises a set of first information generated by each module in the N modules based on the to-be-tested data when the to-be-tested link is operated; comparing the first information set with the second information set to generate a comparison result; and based on the comparison result, determining whether the to-be-tested link operates normally. By comparing the data generated by each module in the to-be-tested link with the normal data, whether the to-be-tested link is abnormal or not is further determined, so that whether each module in a complex link is abnormal or not can be detected in the testing process, the comprehensiveness and accuracy of link testing are improved, and occurrence of abnormal conditions in a subsequent production environment is reduced.

The invention relates to a belt drive dual gear feeding mechanism of an FDM type 3D printer. The belt drive dual gear feeding mechanism comprises a stepping motor, a box body and a cover body. The bottom of the box body is fixed to the output end of the stepping motor, and the output end stretches into the box body. The cover body covers an opening in the top of the box body, and two second through holes are formed in the cover body in a spaced manner. A driving wheel and two driven wheels which are in transmission connection through one synchronous belt are arranged in the box body. The driving wheel is fixed to the output end. The two driven wheels are fixed to the lower ends of two rotating shafts correspondingly. The upper ends of the rotating shafts stretch out from the correspondingsecond through holes and are each connected with a feeding gear after stretching out. A pressing assembly capable of adjusting pressing pressure is arranged on the cover body and comprises two pressing bearings, and the pressing bearings are in one-to-one correspondence to the feeding gears. The belt drive dual gear feeding mechanism has the advantages that the two feeding gears rotating synchronously are adopted for feeding, and the slippage phenomenon is eradicated; the pressing pressure can be adjusted continuously, and applicability is good; and the influence of heating of the stepping motor on 3D printing wires is reduced.
