Method for improving temperature and humidity control precision of storage battery plate curing chamber

Abstract

The invention provides a method for improving the temperature and humidity control precision of a storage battery plate curing chamber, and belongs to the field of temperature and humidity automatic control of storage battery plate curing chambers. The method comprises the following steps: firstly, pre-storing i groups of common process data in a touch screen, and selecting a group of data as a current operation process parameter; then entering an automatic control mode, controlling a system CPU to automatically call in a temperature and humidity control program according to a set temperatureand humidity intelligent control strategy, and sequentially completing curing and drying procedures according to preset time of each process section; and finally, in different process sections, afterthe system is stabilized, performing self-tuning on PID parameters of the current working condition through an upper computer, and automatically storing the tuned optimal parameters in a CPU memory. The method improves the adaptability of the control system to the operation condition when the parameter or state changes, and has the advantages of the high temperature and humidity control precision,fast system response, the small overshoot, energy saving and the like.

Description

technical field [0001] The invention mainly relates to the field of automatic control of room temperature and humidity for storage battery pole plate curing, in particular to a method for improving the control accuracy of storage battery pole plate curing room temperature and humidity.
