System and method for controlling incubation of silkworm eggs

Abstract

Provided are a system and method for controlling incubation of silkworm eggs. The system is formed by an industrial personal computer, a PLC, a route inspection instrument, a plurality of control panels, a plurality of temperature and humidity transducers and a plurality of execution units. The industrial personal computer is connected with the PLC through a PC/PPI cable, the PLC is connected with the route inspection instrument through a parallel data interface, the route inspection instrument is connected with all the temperature and humidity transducers, the control panels are connected with the execution units, and all the control panels are connected to the PLC; the route inspection instrument carries out timing acquisition on temperature and humidity signals and sends data to the PLC through the parallel data interface in real time; after the PLC reads the data, the data are compared with set temperature and humidity values in the industrial personal computer, air conditioners, heaters, humidifiers and motors of the execution units are driven by the control panels, and accordingly temperatures, humidity and illumination of incubation rooms accord with incubation requirements. According to the system and method, silkworm egg embryos are more uniformly illuminated, grow in good order and are incubated more uniformly, the incubation rate is increased, and incubation date accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic control. Background technique [0002] Acceleration of silkworm eggs is the key basic project of sericulture production. It is a technology that people protect silkworm eggs under suitable environmental conditions such as temperature and humidity according to the development law of silkworm egg embryos, and promote the normal development of embryos in eggs until hatching silkworms. process. Silkworm eggs at different development stages have different requirements on temperature, humidity, light and other conditions. Therefore, the control of environmental factors in the silkworm egg accelerating process is directly related to the quality of silkworm egg accelerating greening. At present, the main control methods of silkworm egg acceleration measurement and control technology include instrument control and single-chip microcomputer control, and some backward areas even stay at the stage of manu...

AI Technical Summary

Problems solved by technology

Traditional manual control is time-consuming, labor-intensive, and has poor precision. The control of temperature, humidity, and light often fails to achieve the expected results, and it cannot realize the 360-degree automatic transposition of silkworm eggs at regular intervals, and cannot make each hatching hatch evenly; instrument control It is relatively simple, but the adaptability of the control is limited; although the single-chip control has strong performance, but the reliability is low, and the human-computer interaction ability is poor, and the data processing ability is limited
