Description

Technical Field

[0001] The present invention relates to the technical field of intelligent control, and in particular to an intelligent porcelain furnace control system based on the Internet of Things. Background Art

[0002] A porcelain furnace is a device specifically used for fabricating and repairing dentures and plays a crucial role in prosthodontics; this device ensures the quality and durability of dentures through precise control of temperature and vacuum pressure, thereby providing patients with comfortable, aesthetically pleasing, and fully functional false teeth; the working principle of a porcelain furnace is to fuse a metal or ceramic coping and ceramic material together through high temperature to form a solid denture structure; this process requires precise temperature control and time management to ensure the best fusion effect of the materials; the use of a porcelain furnace not only improves the production efficiency of dentures but also greatly enhances the stability and durability of the repair effect; therefore, the porcelain furnace has an irreplaceable position in the field of oral repair and is one of the key devices to ensure the quality of dentures.

[0003] With the continuous progress and innovation of technology, intelligent control technology has been widely applied and promoted in various industries and fields; as an indispensable and important device in the denture processing process, the degree of intelligence of the control system of a porcelain furnace largely determines the level of production efficiency and the quality of products; however, there are still some common problems in the porcelain furnace control systems currently seen in the market, such as complex maintenance processes, inconvenient management operations, and energy waste; these problems not only affect production efficiency but also increase production costs and reduce the competitiveness of products; therefore, there is an urgent need for an efficient and intelligent control method and its corresponding system to improve and optimize the existing porcelain furnace control system to improve production efficiency, ensure product quality, and achieve reasonable utilization of energy.

[0004] In the existing designed denture porcelain furnaces, up to hundreds of porcelain firing programs need to be set, and nearly 20 different parameters need to be adjusted for each program; the adjustment process of these parameters is quite complex, and the operation steps are also rather cumbersome when selecting and calling these programs. Therefore, overall, the operation process takes a long time and brings certain inconvenience to users. Summary of the Invention

[0005] The present invention aims to provide an intelligent porcelain furnace control system based on Internet of Things technology to solve the problems existing in the prior art, improve the control efficiency, production efficiency, and product quality of the porcelain furnace, and reduce energy consumption and production costs.

[0006] The present invention adopts the following technical solutions to achieve the above object: An intelligent porcelain furnace control system based on the Internet of Things. The intelligent porcelain furnace control system has a cloud server for storing the operation data and program control of the porcelain furnace; the cloud server uses big data analysis technology to analyze the operation data of the porcelain furnace in real time and remotely control the porcelain furnace according to the received control instructions; the intelligent porcelain furnace control system is provided with a controller and a machine vision module; the controller is used to receive the operation parameters of the porcelain furnace collected by the sensor system, process and analyze the operation parameters, and generate control instructions; the controller controls the movement mechanism, the temperature and pressure inside the furnace of the porcelain furnace; the controller also includes a display interface for displaying the operation status and parameters of the porcelain furnace and providing an operation interface; the controller also includes an intelligent algorithm module, which can automatically adjust the control strategy according to the real-time operation data of the porcelain furnace and the preset process parameters to optimize the porcelain process; in addition, the controller also has a fault diagnosis function, which can monitor the operation status of the porcelain furnace in real time. Once an abnormality is detected, an alarm will be issued immediately and corresponding protection measures will be taken to prevent equipment damage and production accidents. The machine vision module is used to detect the quantity and type of the dentures to be sintered and send them to the controller and the cloud server. The controller and the cloud server automatically adjust the power output of the porcelain furnace by analyzing the data to meet the sintering requirements of different dentures, achieving reasonable utilization of energy. At the same time, the cloud server can classify and record various data in the porcelain process according to the denture data. The intelligent porcelain furnace control system also includes a data storage module for recording all parameters and states in the porcelain process, facilitating subsequent quality tracking and process improvement.

[0008] The machine vision module uses a two-dimensional or three-dimensional camera, which can capture the production project code and information, identify the precise image of the denture, and analyze the size, shape and position of the denture through image processing technology to ensure the accuracy and consistency of the porcelain process.

[0009] The cloud server scans and obtains restoration denture information data such as the quantity and type of the porcelain-fused-to-metal restoration denture through the scanning system, and automatically calculates the required optimal porcelain parameters through the intelligent algorithm of the cloud server, and transmits them to the controller; or, the controller directly inputs the pressure curve and temperature curve through the program input interface.
