2021-03-09 14:41:22

    According to the actual application of workshop cellar temperature measurement currently used by domestic distilleries, on the basis of widely understanding the current temperature measurement equipment and domestic intelligent wireless temperature measurement technology, a combination of "production, learning and refinement" is formed to complete the project implementation plan. Through the intelligent transformation of the cellar temperature measurement under existing conditions, the transformation from manual to intelligent in Baijiu brewing process is realized. The scattered and non connected production data become the traceable production data, which lays the foundation for observing and discovering the law of liquor making. At the same time, the system makes the production operation more standardized and visual.

          The wireless thermometer developed by our company can realize the real-time temperature measurement of upper, middle and lower points, and transmit the data to the gateway (receiver) through reliable wireless protocol. The gateway transmits the data to the central control computer in the workshop, and the central control computer uploads the data to the server through Ethernet. The server builds a background management system, and regulates different members to carry out division of labor detection through authority setting, At the same time, according to the data input by the chemist, the key points are prompted and sent back. According to the prompts, the production workers optimize the production process of the pit.

        Through transformation, information sharing of Baijiu brewing process management and business departments can be realized, office automation and work efficiency can be realized. Digital real-time temperature measurement technology can reflect the temperature change rule of fermentation process, and more accurately enhance Baijiu brewing process. Online filling and automatic report generation can be ensured through data analysis of Laboratory Department, so as to ensure data real and timely. It can automatically report the overall operation of the equipment, reliable system design can greatly reduce the later management and maintenance of the equipment; powerful background management platform, fully realize the visual operation, provide clear data information and convenient operation to the manager to the maximum extent, reserve more background interfaces, lay the foundation for software customization and subsequent extensible development Good foundation. The overall goal of "reducing labor intensity, reducing management costs, improving management level, improving economic benefits and improving the comprehensive quality of employees" has been achieved.

PC software

According to the actual use habits and requirements of the factory, we compile the intelligent production software which is most in line with the operation of the front-line production workers. We use the standard programming language, optimize the code to ensure the safe and efficient operation of the software. We set up powerful encryption means in the data transmission to ensure the safe transmission of data. We can configure the server privately and arrange the firewall free of charge, so as to ensure the safe operation of the software It is inconsistent with the corresponding open permissions of users, so the management system should be optimized. Background management interface, depth optimization of human-computer interaction。
