The invention relates to a technical method for determining the damage boundary of a subsided farmland and belongs to the technical field of surveying and mapping as well as environmental monitoring. The method comprises the following steps: selecting corresponding remote sensing data and non-remote sensing data to determine a preliminary area of subsidence; extracting subsided water area boundary information in the subsidence area by using multi-scale wavelet transform edge detection, establishing an index model of subsidence land boundary buffering, buffering the boundary of a subsided water area by using the model and obtaining subsidence boundary information of the area to be surveyed and ground subsidence depth information; obtaining DEM (Digital Elevation Model) elevation information through a method for analyzing photogrammetric survey; determining and supplementing the subsidence boundary by using elevation variation information data of the area to be surveyed, wherein the elevation variation information data of the area to be surveyed are obtained through difference analysis of DEMs at different time phases; and then eliminating the subsidence land boundary information caused by coal mining activities; and finally obtaining subsidence land boundary and subsidence depth information of the area to be surveyed. According to the invention, the boundary of the subsided farmland can be rapidly determined and basic support can be provided to compensation and treatment of the subsidence land.

The invention discloses a connecting method and a connecting body for a lingual side of a molar belt ring. A substrate is fixed on the surface of the lingual side of the molar belt ring; a key way which is vertical to the axis of the molar belt ring is arranged on the substrate; a key and a fine metal wire for fixing are arranged on one end of a connecting rod; the key is inserted to the key way to form a connecting mechanism; the fine metal wire is clamped to the lower side of the key way to fix the whole connecting rod; force is applied to the molar belt ring by opening or bending the fine metal wire to dismount the molar belt ring. The substrate is fixed on the surface of the lingual side of the molar belt ring, and the key on the connecting rod can be vertically arranged in the key way on the substrate, so that an arch expanding device, a strengthening and supporting device and the molar belt ring are connected simply and efficiently, and can be simply dismounted for being regulated and applied force to re-wear the molar belt ring. Welding or tying needed for connecting the molar belt ring is avoided, so that processing time is saved; and moreover, the belt ring is not needed to be dismounted in every adjusting process, so that the pain of a patient is greatly relieved, and consultation hours is saved.

The invention discloses a pediatric body position therapy fixer, comprising a base plate, an electric push rod, a table plate, a fixed seat, a guide plate, a fixed shaft, a foot support plate, a fixed sleeve, a guide rod, a backing plate, a filling and suction pump, and a Y-shaped tube , air cushion, this pediatric body position therapy fixer has ingenious structure and powerful functions. Firstly, through the design of supporting standing mechanism, it can realize the standing posture rehabilitation training of children with cerebral palsy, and achieve the purpose of correcting the children's subsequent walking posture. Secondly, through the built-in multi- The cooperation effect of the group adjustment mechanism satisfies the standing needs of different heights and different angles. Finally, through the above, the clinical practicability is expanded and the purpose of popularization and application is achieved.

The invention discloses a heavy and extra-large structural member saw-cutting device and a saw-cutting method thereof. A two-wheel type sawing machine for saw-cutting a large structural member requires the matching of large-dimensional saw belt wheels, so that the production cost is greatly improved. The invention relates to the heavy and extra-large structural member saw-cutting device which comprises a rack, a three-wheel saw-cutting mechanism, a feeding hydraulic oil cylinder, a working table, a guiding and correcting mechanism, a workbench and a clamping assembly. The three-wheel saw-cutting mechanism comprises a saw frame, a driving belt saw wheel, a saw belt, a middle saw belt wheel and a driven saw belt wheel. The guiding and correcting mechanism comprises a guiding block, a correcting movement plate, a correcting swinging worm, a correcting swinging worm wheel, a correcting drive piece and a torsion motor. The working table comprises a swinging table, a moving table, a transverse movement drive piece, a swinging spring and a swinging air cylinder. According to the heavy and extra-large structural member saw-cutting device and the saw-cutting method thereof provided by the invention, a traditional two-saw-belt-wheel transmission structure is changed into a three-saw-belt-wheel transmission structure, so that the defect that the conventional two-saw-belt-wheel sawing machine requires the diameter of each saw belt wheel to be larger than the diameter of a workpiece is overcome, and the volume and the height of the whole machine are greatly reduced.

The present application discloses a light source calibration method and system, wherein, the light source calibration method first obtains the standard white color of the test camera module under the standard light source and the input luminance value of the first preset value by testing the camera module under the standard light source. Balance calculation parameters; then use the standard white balance calculation parameters as the calibration standard of the light source of the platform to be tested, use the same test camera module to test under the light source of the platform to be tested, and when the obtained test white balance calculation parameters and When the difference between the standard white balance calculation parameters is less than the preset threshold, the current input brightness value is used as the calibration input brightness value, so that when the input brightness value of the light source of the platform to be tested is the calibration input brightness value, it can obtain the same input brightness as the standard light source. The value is an illumination environment with similar brightness when the value is the first preset value, thereby realizing the purpose of calibrating the light source of the platform to be tested.
