This invention discloses a method, system, and computer equipment for electronic data forensics in police vehicles. The method includes: confirming whether the vehicle's onboard data storage device has read permissions; if read permissions exist, the investigating officer performs bidirectional authentication between the vehicle-mounted forensics equipment and the identity authentication module in the public security platform, activating and authorizing the secure, legal, and operable nature of the vehicle-mounted forensics equipment; if read permissions do not exist, data is directly read from the vehicle-mounted data storage device; and different data integrity checks and extractions are performed based on the two communication protocol types of the vehicle-mounted data storage device. This invention, in police enforcement scenarios, overcomes permission barriers and equipment damage constraints, enabling rapid acquisition and analysis of onboard data.

The present application relates to the technical field of lithium battery production, and particularly relates to a kind of detection method of lithium ion battery positive pole slurry stability, comprising the following steps: S1: immediately after slurry preparation, sample is removed to rheometer, amplitude scanning test is carried out, and storage modulus G' and phase angle delta are recorded;S2: slurry is prepared again, immediately after slurry preparation, it is removed to rheometer, and stress scanning test is carried out, and yield stress is recorded;S3: the stability of slurry is evaluated in combination with yield stress, storage modulus G' and phase angle delta three indexes.The present application simultaneously collects yield stress, storage modulus G' and phase angle delta three dimensional indexes, respectively represents the strength, stiffness and solid-like characteristics of slurry, realizes the multi-angle, three-dimensional evaluation of internal network structure stability of slurry, and solves the technical problems that the existing detection method has poor accuracy, long time consumption, pre-treatment destroys the original structure of slurry and the single evaluation index leads to misjudgment.

This utility model discloses a high-efficiency grinding device for livestock feed raw materials, including a grinding chamber and a top cover fastened to the top surface of the grinding chamber by bolts. A fixed platform is fixedly connected to the outer surface of the grinding chamber, a crushing device is provided on the inner wall of the grinding chamber, and a screening device is fixedly connected to the bottom surface of the grinding chamber. The crushing device includes a crushing rod, a transmission roller, a connecting bearing, a rotating shaft, and a motor. In the process of conveying materials from the feed hopper into the grinding chamber, the crushing device and the crushing rod inside can crush the raw materials, allowing the materials to be restored during the conveying process to ensure the original quality and stability, so as to facilitate the use of subsequent feed production processes. For materials with large particles, lumps that do not meet the requirements of subsequent processing, or impurities in the materials, secondary optimization treatment is carried out by vibrating screen, which further reduces the screening process and greatly saves manpower and resources.

The application discloses a gynecological secretion sampling device, which comprises a first cylinder, a second cylinder and a sampling execution mechanism. The first cylinder is provided with a first sampling through hole and a first accommodating cavity. The first sampling through hole penetrates through the first cylinder along the wall thickness direction of the first cylinder to connect the outside with the first accommodating cavity. The second cylinder is rotatably sleeved in the first accommodating cavity. The second cylinder is provided with a second sampling through hole and a second accommodating cavity. The second sampling through hole penetrates through the second cylinder along the wall thickness direction of the second cylinder to connect the first accommodating cavity with the second accommodating cavity. The sampling execution mechanism is arranged in the second accommodating cavity and is used for obtaining a secretion sample. The gynecological secretion sampling device solves the problem that the existing gynecological secretion sampling device is prone to sample pollution due to insufficient sealing performance.

The invention discloses a coal seam closed fixed-point sampling device with a built-in sampling tank and a use method of the coal seam closed fixed-point sampling device. The coal seam closed fixed-point sampling device comprises a drilling tool and a drill bit seat integrally formed with the drilling tool, and a drill bit is assembled on the drill bit seat in a threaded mode; a drilling tool cavity is formed in the drilling tool in the axial direction of the drilling tool, a coal sample tank is arranged in the drilling tool cavity, the side, facing the drill bit, of the coal sample tank is in an open shape, and a ball valve is rotationally installed at the open position. The middle of the drill bit is in a through hole shape and is communicated with the interior of the drilling tool, and the ball valve acts to enable the interior of the coal sample tank to be communicated with the middle of the drill bit in the rotating operation process of the drill bit. According to the method, sampling can be carried out in situ on the coal seam, the loss of gas in the extraction and transportation process of the coal sample is effectively avoided, the authenticity and reliability of the measured gas content data are ensured, and compared with the problems of gas dissipation and measurement result distortion caused by coal sample exposure in the prior art, a more accurate gas content measurement result is provided; powerful data support is provided for coal mine gas prevention and control and coal bed gas development.
