Embodiment

[0039] The temperature compensation control method of the embodiment of the present invention, such as figure 1 shown, including the following steps:

[0040] S1. According to the output temperature value T set by the user set with temperature offset T offset Calculate the target temperature value T that actually needs to be output target , the temperature offset T offset The initial value is 0, and the heating wire is controlled to heat to the target temperature value T target ,Calculated as follows:

[0041] T target =T set +T offset ;

[0042] Set the initial temperature offset T offset is 0, at this time, the target temperature value T target Equal to the output temperature value T set by the user set ;

[0043] S2. Compare the temperature value T detected by the temperature sensor sensor with the target temperature value T target The value of the temperature detected by the temperature sensor is the temperature inside the component to be heated;

[0044] Th...

Abstract

The invention relates to the technical field of temperature compensation control. In order to solve the problem of low heating temperature control accuracy, the invention provides a temperature compensation control method, which obtains a new target temperature value by calculating a temperature offset and correcting the target temperature value that is actually required to be output, and controlsthe heating wire to heat to the new target temperature value. A temperature compensation control process compensates that heat dissipation amount affect by the ambient temperature and the temperaturesensor detection error, It can reduce the difference between the user's setting temperature and the temperature that the user actually feels, reduce the disturbance of the environment temperature tothe temperature control, and is especially suitable for the heating control of the intelligent toilet seat, automobile seat cushion and other parts which are in direct contact with human body and havehigher requirements for temperature control.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a temperature compensation control method. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the comfort of sensory experience, such as smart toilet seats, car electric heating seats and other parts that require direct contact with the human body. Especially in winter, in order to avoid skin contact and feel cold and uncomfortable, Most of today's seat rings or cushions have built-in heating wires to heat them, but due to the sealing of the built-in heating wires in the heating system, the exposure of the external structure, the heating inertia of the heating wires, and the detection error of the temperature sensor, they are affected by the ambient temperature. Larger, with the change of ambient temperature, the relationship between heating and heat dissipation is unbalanced, so the actual temperatur...
