The utility model provides an AGV forklift goods detection stabilizing device, and belongs to the technical field of automatic guided vehicles. The device comprises a fixing plate, a main goods detecting part, a central goods detecting part, an auxiliary goods detecting part and a control unit. The main goods detecting part comprises two goods detecting assemblies, each goods detecting assembly is provided with a fixing frame, a goods detecting baffle, an elastic limiting piece and a first proximity switch, and when the included angle between the goods detecting baffle and the fixing frame is smaller than or equal to 5 degrees, a first detecting signal is output; the central cargo detection part comprises an inductive sensor, detects the cargo insertion state and outputs a second detection signal; the auxiliary goods detecting component comprises a second proximity switch, and when goods enter the sensing range, a third detection signal is output. The control unit receives the three paths of signals at the same time, and outputs a signal of detecting goods in place only after the three paths of signals are all continuously conducted for at least preset time. According to the utility model, the cargo insertion stability is ensured through multiple detection mechanisms, and the safety and reliability of the operation of the AGV forklift are improved.

The application relates to the technical field of image processing, and discloses an image processing model acquisition method and device and an image processing method and device. In the method, a sample image is preprocessed by using a current image processing model to obtain a corresponding representation image; the preprocessing comprises at least one of the following four operations: a clipping operation on an edge region with a gray value less than a first threshold value, an inhibition operation on a feature response of a region with a texture change degree less than a second threshold value, a brightness equalization operation on a global region, and a decision processing operation on a region with a color component variance less than a third threshold value; the representation image is hashed by using the current image processing model to obtain a hash vector of the sample image; and the current image processing model is adjusted in parameters based on a contrast loss function until a target image processing model is obtained. The above method weakens redundant information in the sample image by preprocessing the sample image, and realizes more accurate and effective hash vector output.

The application relates to the technical field of eye movement instruments, and discloses an autism eye movement track recognition instrument, which comprises an instrument base plate, a playing device is fixedly installed at one end of the instrument base plate, a head limiting mechanism is rotationally assembled at the other end of the instrument base plate, the playing device is used for playing materials, and an eye movement tracking camera for collecting the eye picture of a patient when the patient watches the materials is hiddenly installed on the playing device. The autism eye movement track recognition instrument limits the head position of the patient through the swingable head limiting mechanism, the swing of the head of the patient can reduce the uncomfortable feeling, the eye movement tracking camera is driven to move synchronously through a power transmission assembly, the eyes of the patient can be kept facing the camera during the test process, the eyes of the patient are prevented from deviating from the shooting range of the camera, and the eye movement tracking camera is prevented from moving and lagging behind when the head of the patient swings, so that the shooting of the eyes is not delayed, and the accuracy of collecting the eye movement track of the patient is ensured.

The utility model relates to the technical field of water permeability testing, in particular to light concrete block water permeability testing equipment which comprises a detection table, a mounting groove is formed in one end of the top of the detection table, and a filter frame is mounted in the mounting groove. After the test mold is driven to descend to be tightly attached to the top of the concrete block, water is injected into the test mold for water permeability test, and the situation that water leaks from the bottom of the test mold, water loss is caused, and the test accuracy is affected is avoided by arranging a sealing gasket; the two movable blocks oppositely move to drive the connecting plate to move, the test mold is clamped by four groups of limiting frames, the disassembly and assembly are convenient, the test molds with different pipe diameters can be conveniently limited and fixed, and the permeation amounts of concrete blocks and water in different contact areas can be conveniently tested by replacing the test molds with different pipe diameters, so that the test result is more accurate, and the practicability is better.

The application discloses a kind of based on visual aid air conditioning system safety valve, belong to visual aid technical field, solve these problems existence certain concealment, for visual identification technology, it is difficult to judge dynamic pressure fluctuation condition by static image, and whether the rigidity of safety valve internal spring is appropriate Problem. Including safety valve body, three-axis vibration sensor being set on the valve body in safety valve body and collecting and outputting vibration signal, wideband pressure sensor being set in safety valve body entrance and collecting dynamic pressure change in safety valve body. The application detects the vibration and pressure condition of safety valve using three-axis vibration sensor and wideband pressure sensor, completes primary detection;Secondary detection is carried out by cooperating photoelectric pulse statistics and visual identification, and the final judgment is output combined with two-stage detection results, to ensure accurate identification of safety valve frequency jump or flutter, to avoid the influence of single visual identification technology on accuracy.

This utility model provides a glass processing adhesive coating device, relating to the field of glass processing technology. It includes a mounting base, a limiting component disposed on one side of the mounting base, a suction cup disposed on the outer top of the mounting base, a locking component disposed above the mounting base for locking the position of the suction cup, and a base plate disposed on one side of the suction cup. As the glass size increases, the receiving plate expands outwards, automatically increasing the waste adhesive receiving range. This allows for more comprehensive collection of waste adhesive generated during the coating process, reducing environmental pollution and equipment cleaning burden caused by waste adhesive spillage. It ensures a clean processing environment and reduces subsequent cleaning and maintenance costs. Overall, this device demonstrates outstanding advantages in flexibility, efficiency, precision, and environmental friendliness, effectively meeting the actual needs of glass processing adhesive coating.
