The invention discloses a geological three-dimensional model source data evaluation method, and relates to the technical field of geological models, and the method comprises the steps: obtaining a drilling data point set and grid system parameters, mapping drilling data points to a grid system, and obtaining a grid coverage statistical result; according to a grid coverage statistical result, calculating transverse and longitudinal distribution indexes, and performing distribution rationality evaluation processing to obtain a source data spatial distribution coefficient; based on the source data space distribution coefficient and the grid system parameters, obtaining a root-mean-square error precision report by calculating the shortest distance from the control point to the surface of the grid system; according to the root-mean-square error precision report and the grid system parameters, whether a blank zone exists in the geologic model or not is checked, a model integrity coefficient is calculated, and a final quality evaluation result is obtained. The invention provides a geological three-dimensional model source data evaluation method, and aims to solve the problem of inaccurate model blank zone detection caused by one-sided distribution evaluation and neglecting of vertical resolution and spatial correlation in the prior art.

This application relates to a paint applicator, including a frame, a mounting frame, and an applicator assembly. A main unit is mounted on the top of the frame, and a mounting frame is fixedly mounted on one side of the top of the frame. The mounting frame consists of a main frame, an L-shaped frame, and a cross frame. The main frame is movably mounted on the bottom of the L-shaped frame, and a cross frame is movably mounted on one side of the L-shaped frame. A motor is mounted on one side of the bottom of the cross frame, and the applicator assembly is mounted on the bottom of the cross frame. The applicator assembly consists of a gear and an arc-shaped rail. The arc-shaped rail is fixedly mounted on the bottom of the gear, and a sprayer is mounted on the outside of the arc-shaped rail. This invention achieves rapid, all-around spraying of the surface of a circular spherical mound through the rotation of the arc-shaped rail and the movement of the sprayer, significantly improving spraying efficiency. Furthermore, because the sprayer sprays in close contact with the surface of the spherical mound and the spraying parameters can be adjusted as needed, uniform and thorough spraying is ensured, improving spraying quality. Automated operation reduces manual intervention, lowers the operator's workload, and improves operational safety.

The invention discloses a polarization encryption one-way data ferrying device and method, relates to the technical field of data security transmission, and is suitable for isolated network environments such as a vehicle detection station and the like. The device comprises an integrated ferry host, a built-in transmitting / receiving integrated mainboard, a data access module, a polarization encryption module, an optical transmitting / receiving module, a polarization demodulation module and a data output module which are in one-way connection through a high-light-transmittance optical fiber link. The method comprises the following steps: accessing data through the vehicle inspection data interface, encoding the data into an optical signal through the polarization encryption module for dynamically updating a secret key, demodulating the optical signal after unidirectional transmission, and completing format conversion and integrity verification by the data output module. The device does not need to depend on a physical medium and an external network, physical layer encryption is combined with a dynamic secret key to improve safety, the optical link transmission rate reaches 10 Gbps, the device is integrally designed, configuration is simplified, cost is reduced, modules can be flexibly replaced, and efficient and safe one-way data ferrying is achieved.

This invention discloses a heat exchanger descaling system and method based on digital imaging technology. The method includes: a handheld operating unit; a rod having a proximal end and a distal end, the proximal end being connected to the handheld operating unit; a descaling head rotatably disposed at the distal end of the rod; a driving device for driving the descaling head to rotate; an image acquisition unit disposed at the distal end of the rod, its imaging area covering the area in front of the descaling head; a display device disposed on the handheld operating unit and electrically connected to the image acquisition unit for real-time display of images acquired by the image acquisition unit; and a dosing pipeline arranged along the rod, having a dosing outlet located at the distal end of the rod. This application integrates three core functions—image observation, chemical dosing, and mechanical descaling—into a handheld device, greatly simplifying operation, shortening cleaning time, and reducing labor costs. Furthermore, the real-time feedback from the image acquisition unit and the display device enables visualized operation and precise cleaning.
