Embodiments of the present application provide a kind of helmet detection method, device, storage medium and system, its method includes: obtaining the sample image set of target object;Sample image set is carried out attribute identification, to obtain first label information and second label information;Based on first label, first label confidence, second label and second label confidence, initial neural network model is carried out model training operation, to obtain target neural network model;Through the target neural network model, label confidence analysis is carried out to target image information, to obtain the label confidence information of target image;In the case where the first confidence is greater than the first threshold value, the first label is contained in the label confidence information, and posture adjustment instruction is sent to target object;In the case where the second confidence is greater than the first threshold value, the second label is contained in the label confidence information, and alarm operation is executed.The present application solves the problem of low helmet recognition accuracy, thereby improving the accuracy of helmet recognition.

The utility model relates to valve sealing detection technical field discloses a kind of flange valve sealing detection equipment, including shell, shell side wall is fixedly connected with display screen, the shell inside is fixedly connected with shower nozzle, the rotating cylinder is rotatably connected to the shower nozzle outer wall, the rotating cylinder outer wall is fixedly connected with rotating disc and gear, the shell inside is provided with clamping assembly;The clamping assembly includes cylinder, the cylinder output end is fixedly connected with fixed plate, the fixed plate side wall is fixedly connected with rack, the rack is engaged with the gear, the gear outer wall is rotatably connected in shell inner wall.In the utility model, fixed plate and rack are moved by cylinder drive, rack drives gear and rotating cylinder to rotate, rotating cylinder drives rotating disc to rotate again, rotating disc drives fixed column, bearing to move, and then drive connecting plate and clamping block to gather, realize flange valve limit, solve the inaccurate problem caused by its detection easy to deviate, improve equipment detection accuracy.

The application discloses a greenhouse agricultural environment layered precision monitoring device, aiming at solving the problems that the prior art cannot detect the greenhouse environment parameters with full height precision, the gas exchange device has high energy consumption, and the natural temperature difference is not effectively utilized. The instrument core comprises a vertical environment monitoring column, a servo motor driven reciprocating screw rod, a lifting monitor, a plurality of groups of magnetic force valves arranged longitudinally and an exhaust fan. The reciprocating screw rod drives the axial reciprocating movement of the lifting monitor. The magnetic repulsion force is used for accurately opening and closing the magnetic force valve at the corresponding height. The built-in temperature and humidity and carbon dioxide sensors are used for realizing the accurate detection of the environment parameters at different heights of the greenhouse. Meanwhile, the exhaust fan and the screw rod can be driven by the temperature difference between the inside and outside of the greenhouse, so that the power-free gas exchange and detection are realized, the operation energy consumption is greatly reduced, and the detection precision and energy-saving and environment-friendly characteristics are combined.

The application relates to an I2C wiring diagnosis method, device, equipment and storage medium. The application matches preset backboard layout information with connection information to determine position information of the same backboard in the backboard layout; after the position information of each same backboard is determined, the hard disk positioning lamp in the backboard identified through the position information is lighted according to a set lighting strategy; the lighting state is read to a register corresponding to the I2C channel through the I2C channel between the mainboard and the same backboard; the first corresponding relationship and the second corresponding relationship are detected through the mapping relationship between the I2C channel and the register to analyze whether the I2C wiring has a problem, wherein the first corresponding relationship is the corresponding relationship between each register and each backboard with different position information, and the second corresponding relationship is the corresponding relationship between each I2C channel and each backboard with different position information, so that whether the I2C wiring between the mainboard and different backboards of the same type has a problem can be effectively detected.
