Temperature control system and method

Abstract

The invention relates to the technical field of plate processing, in particular to a temperature control system which comprises a heat conduction oil heater, a heating oil pipe connected with the heat conduction oil heater and a heat preservation box. The control system is characterized in that the control system further comprises an input unit, a temperature sensor, a temperature adjusting actuator and a controller, and the controller receives signals of the input unit and the temperature sensor and outputs control signals to control the temperature adjusting actuator; a temperature control method is used for controlling the temperature of a heat preservation box and comprises the following steps that S1, a target temperature value is set; s2, acquiring a detection temperature value; s3, calculating the ratio of the detection temperature value to the target temperature value; s4, determining a control signal according to the ratio; s5, controlling the temperature adjusting actuator according to the control signal; and S6, repeatedly executing the steps S2, S3, S4 and S5 according to a preset time interval until the ratio is equal to 1.

Description

technical field [0001] The invention belongs to the technical field of sheet material processing, and in particular relates to a temperature control system and method, which are used for temperature control of an incubator during the sheet material purification process. Background technique [0002] In the prior art, the release of formaldehyde in the plate is accelerated by heating to achieve the purpose of purifying the plate. The specific implementation process is to place the plate in an incubator, and heat the incubator to accelerate the release of formaldehyde to achieve a certain level. Purification effect, heating generally uses heat transfer oil pipes for heat exchange. This method has high thermal efficiency and can quickly perform heat exchange. However, for heating insulation boxes, this method does not have high temperature control accuracy and may cause Plate deformation and damage.
