The temperature of the control module is controlled, and the cooling device is located within the cooling area of the cooling device. The scheme is that the temperature acquisition unit collects the resistance information of the thermal device, and sends the temperature information corresponding to the resistance information to the main control unit, and the main control unit obtains the temperature change information corresponding to the thermal device according to the received temperature information, and The output voltage corresponding to the temperature change information is input to the cooling device, and the cooling device adjusts the working mode of the cooling device according to the output voltage to control the temperature of the module to be controlled, thereby improving the accuracy of controlling the temperature of the module to be controlled.

Specifically, as shown in Fig. 2, the change calculation device receives the temperature value sent by the temperature acquisition unit, obtains the corresponding slope of the temperature change according to the temperature value, and sends the slope as the temperature change information corresponding to the thermal device to the subtraction calculation device ; The subtraction calculation device receives the temperature change information sent by the change calculation device, and subtracts the temperature change command information from the temperature change information to obtain the deviation value (the deviation value is equivalent to the deviation value between the target slope and the actual slope, if the temperature change command information is set to 0 , it means that the temperature of the module to be controlled is kept unchanged or the temperature rise of the module to be controlled is maintained at a minimum value, if the temperature change command information is set to a positive number A, it means that the temperature of the module to be controlled is increased with a slope of A , if the temperature change command information is set to a negative number B, it means that the temperature of the module to be controlled decreases with the slope of B), and the deviation value is sent to the voltage calculation device; the voltage calculation device receives the deviation value sent by the subtraction calculation device, according to the deviation value, determine the corresponding output voltage, and provide the output voltage to the cooling device.

Deviation threshold; the first adjustment parameter may be a group of P (proportional) parameters and I (integral) parameters, the second adjustment parameter may be another group of P (proportional) parameters and I (integral) parameters, the second adjustment parameter An adjustment parameter has a higher adjustment speed (for example, if the proportional parameter is large, the adjustment can be accelerated, the larger the integral constant, the weaker the integral action, and vice versa, the stronger the integral adjustment can make the dynamic response slower).

Specifically, the voltage calculation device receives the deviation value sent by the subtraction calculation device, and when the deviation value is greater than the first deviation threshold and less than or equal to the second deviation threshold, the internal control parameters of the voltage calculation device are automatically set to the first set of adjustment parameters, using the first adjustment parameter to obtain the output voltage; when the deviation value is greater than the second deviation threshold, the internal control parameters of the voltage calculation device are automatically set to the second group of adjustment parameters, and the second adjustment parameter is used to obtain the output voltage.

In one embodiment, as shown in FIG. 2 , the main control unit further includes a voltage limiting device; the voltage limiting device is respectively connected with the subtraction computing device and the cooling device;

The voltage calculation device is used for inputting the output voltage to the voltage limiting device; the voltage limiting device is used for inputting the output voltage to the cooling device when the output voltage is greater than the first voltage threshold and less than or equal to the second voltage threshold; When the output voltage is greater than the second voltage threshold, the second voltage threshold is input to the cooling device; when the output voltage is less than or equal to the first voltage threshold, the first voltage threshold is input to the cooling device.

Among them, as shown in Figure 2, the voltage limiting device can be a limiter, which can be used to limit the upper and lower limits of the voltage output; the first voltage threshold can be a preset voltage threshold, such as the rated voltage of the cooling device, which is equivalent to the voltage The minimum value, the first voltage threshold is less than the second voltage threshold; the second voltage threshold can be a preset voltage threshold, such as the highest input voltage of the cooling device, which is equivalent to the maximum voltage, and a certain margin can also be reserved to prevent the cooling device. damage.

Specifically, the voltage computing device provides the output voltage to the voltage limiting device, the voltage limiting device receives the output voltage provided by the voltage computing device, and when the output voltage is greater than the first voltage threshold and less than or equal to the second voltage threshold, the output voltage is The output voltage is input to the cooling device; when the output voltage is greater than the second voltage threshold, the second voltage threshold is input to the cooling device; when the output voltage is less than or equal to the first voltage threshold, the first voltage threshold is input to cooling device.

Exemplarily, when the module to be controlled stops running or the elevator where the module to be controlled stops running, and the deviation value is lower than the third deviation threshold (the third deviation threshold can be set to be smaller than the first deviation threshold), the Three voltage thresholds replace the first voltage threshold, wherein the third voltage threshold is smaller than the first voltage threshold, eg, the third voltage threshold is set to zero.
