The embodiment of the invention relates to a machine room management system and method based on block chain, which comprises the following steps of: acquiring first identity information and second identity information of a user; wherein, the first identity information comprises identity authentication information, and the second identity information comprises information which is collected on thescene and embodies the biological characteristics of the user; determining an identity authentication result based on the matching of the first identity information and the second identity information; determining whether the user can enter the machine room according to the identity authentication result; generating blocks for the first identity information, the second identity information and theidentity authentication result and storing the blocks through the block chain; on the condition that the user is allowed to enter the machine room, the behavior record of the user in the machine roomis obtained, and a block is generated and stored through the block chain. The authentication process and result of the user entering the machine room, and the user's behavior in the machine room canbe completely recorded through the block chain, so that the subsequent visual inspection and the like can be facilitated, and moreover, the real and effective data can be ensured through the block chain, so that the machine room can be effectively monitored.

The invention relates to a ceramic defect visual inspection method. An SVMD is a user interface and dragging type interactive mode using an image as the center; a concise and efficient work flow process is provided for a user; the system complexity is simplified; the technical requirements on operators are reduced; a system development defect detection module can cover 90 percent or more defect types in industry; particularly, some difficult detection items are overcome, so that the SVMD has the competitiveness in the same industry. The SVMD is widely applied to the industry of parts relevant to ceramics and the like.

The invention relates to the technical field of touch screen production, in particular to a glass cover plate preparation process. The preparation process comprises the following steps: the first stepof rough shape cutting; the second step of CNC forming; the third step of first ultrasonic cleaning; the fourth step of first visual inspection; the fifth step of strengthening treatment; the sixth step of flat grinding treatment; the seventh step of second ultrasonic cleaning; the eighth step of plasma treatment of a glass cover plate; the ninth step of placing the glass cover plate in a printing fixed seat; the tenth step of automatically checking the glass cover plate for visual defects; the eleventh step of placing IR ink and alignment line ink in a printing frame; the twelfth step of starting a double scraper printing machine; the thirteenth step of drying and curing; the fourteenth step of third ultrasonic cleaning. The glass cover plate preparation process has the advantages of being high in production efficiency, capable of saving resource and energy and low in product defect rate.

The invention discloses a visual end feedback control method based on 3D printing, and the visual end feedback control method based on 3D printing includes the following steps that a model is input toa 3D printing robot arm; visual inspection printing model is carried out; compared with an original model of a robot arm, difference is produced and sent to PLC; and finally, the PLC moves the chassis to compensate and feeds back to the robot arm. The invention provides a novel feedback control method and system for 3D printing, and the novel feedback control method for 3D printing can significantly improve the precision of 3D printing. The visual end feedback control method based on 3D printing feeds back to the vision and the robot arm through a method of low disk movement and corrects theprinting position error in real time.
