The invention discloses a jacquard shed fast adjustment device of a loaded griffe mechanism. The device includes: inner and outer griffe mechanisms symmetrically arranged near the inner and outer sides of a left and a right wallboard, alternate shed adjusting mechanisms, shed adjusting mechanisms, as well as large and small shed output shafts. The inner and outer griffe mechanisms respectively have paired griffe frame plates, hanger rod groups and griffe groups. Each end face and each end of the large and small shed output shafts are both equipped with radial strip teeth and positioning slots. The shed adjusting mechanisms and the alternate shed adjusting mechanisms both include positioning wedge blocks, shed adjusting tooth blocks, pin shafts and upper seats. The positioning slots are respectively provided with wedged positioning wedge blocks. The radial strip teeth are respectively engaged with the shed adjusting tooth blocks. Connecting rods are respectively hinged to the vicinity of each end of the paired griffe frame plates. The upper ends of the connecting rods are all fixed with the upper seats. The upper seats, the shed adjusting tooth blocks and the positioning wedge blocks are positioned through the pin shafts and are fixed. With no need for unloading, the device disclosed in the invention can realize fast shed adjustment, and has the advantages of high adjustment precision as well as large scope.

The invention relates to a primer used for detection of pathogenic microorganism so as to detect pathogenic microorganism such as vibrio cholerae, pathogenic escherichia coli, campylobacter jejuni, Yersinia enterocolitica, parahemolytic vibrio, salmonella, shigella and Listeria monocytogenes, etc. The invention also relates to a method by using the primer to do multiple amplification detection and further relates to applications of the primer for detection of pathogenic microorganism in preparation of detection agent and further relates to kits containing the primer for the detection of pathogenic microorganism.

The invention discloses a conditioning conversion circuit for airborne time sequence and initiating explosive device test and belongs to the field of missile test control. The circuit comprises a multipath twistor switch SK1, a current-limiting resistor R1, a current-limiting resistor R2, a photoelectric coupler U1, a relay K1 and a relay K2, wherein the twistor switch SK1 is a gating device, during the time sequence test, an SK1-1 gear is conducted, and input time sequence signals are subjected to conditioning conversion; and during the initiating explosive device resistance test, an SK1-2 gear is conducted, and input initiating explosive device signals are converted. Compared with the prior art, the conditioning conversion circuit has the beneficial effects that the development cost is saved, the preparation workload before the test is reduced, and the maneuverability of the system is improved; the design thoughts of centralized planning and time sharing application are adopted, the development resource is more centralized, the real-time state monitoring and management is convenient, and the reliable time-sharing completion of conditioning conversion of different signals can be ensured; and the problem of an interface circuit between an airborne electric system and test control equipment is solved, and the effectiveness and the reliability of collected signals are ensured.

The present invention relates to image recognition, and in particular to a method for automatically presenting information on the live broadcast screen of an electric competition. The H5 operation interface is opened on the PC2 and connected to the OB machine of the OB electric competition. When valid data or information is updated on the screen on the PC2 , click the relevant button on the operation interface to trigger the screenshot operation, and PC2 judges whether to recognize image information or text information according to the relevant button pressed in S1. After PC2 judges the recognized image information, it performs binarization and grayscale processing on the screenshot and Calculate the threshold, because the recognized image information is always distributed in the fixed position of the screenshot, so the processed screenshot in S3 can be divided according to the coordinates set in advance, and PC2 selects the corresponding coordinates in S4 according to the relevant button pressed in S1 The segmented picture is compared with the RGB value of the selected segmented picture and the picture template in the database; the technical solution provided by the invention effectively overcomes the defects that the subtitle cannot be automatically updated according to the live picture and the image information recognition speed is slow.
