Real-time clock judgment device and method for bulk curing barn controller

Abstract

The invention provides a real-time clock judgment device and a real-time clock judgment method for a bulk curing barn controller and relates to a bulk curing barn tobacco flue-curing controller. At present, in order to display the current time, a real-time clock chip and a button battery for supplying power for the real-time clock chip are arranged on a hardware circuit, so the hardware cost is increased, the reliability is reduced, and a tobacco grower needs to exchange the button battery, which is troublesome. The real-time clock judgment device comprises an input device, a prompting device, a display device, a memory, a temperature sensor, a flue curing times judgment unit and a real-time clock unit, wherein the flue curing times judgment unit is connected with the temperature sensor and the memory; and the real-time clock unit is connected with the input device, the prompting device, the display device, the memory and the flue-curing times judgment unit. According to the technicalscheme, the clock chip is not provided, so the hardware cost is reduced, the reliability of the products is improved, the problem about clock display is solved and the inconvenience that an operator needs to exchange the battery is avoided. According to the scheme, the rural power grid is instable, the previous power-down time can be read automatically and one flue-curing time can serve as continuous work, so work recording and management are facilitated.

Description

technical field [0001] The invention relates to a flue-cured tobacco controller for a dense barn. Background technique [0002] At present, with the continuous improvement of tobacco leaf quality and the transformation of flue-cured tobacco production organization, flue-cured tobacco production is gradually developing in the direction of scale, intensification, and specialization. my country's curing barn equipment is also constantly innovating and developing. Intensive curing barns have become an important part of flue-cured tobacco production. The direction of development under the new situation of sustainable development. The flue-cured tobacco controller of the intensive barn requires displaying 5 items of the clock, including year, month, day, hour and minute, on the display screen. At present, the main solution is to add a real-time clock chip and a button battery on the hardware circuit, such as a real-time clock chip such as DS1302. Although this method can set the ...

AI Technical Summary

Problems solved by technology

Although this method can set the rear clock at the factory, the tobacco farmers do not need to set the time when using it, but there are two problems. First, it increases the components and hardware costs, and at the same time, it also leads to an increase in the defective rate. Second, because button batteries generally have a service life of 3 years, tobacco farmers need to replace the button batteries themselves, which is also troublesome
