Abstract
A control method is provided and used to place a target object on a test platform in a cabin of a testing device, to sense the temperature of the target object by a temperature response structure, and then to receive temperature signals of the temperature response structure by a controller, where the controller can regulate the pressure inside the cabin to control the air pressure of the cabin, so that the target object can still maintain good heat dissipation under high power consumption.
Claims16
A testing device, comprising:
- a cabin equipped with a test platform therein for placing a target object;
- a temperature response structure for sensing a temperature of the target object;
- a controller communicatively connected with the temperature response structure for receiving temperature signals of the temperature response structure and controlling an internal pressure of the cabin to a pressure value corresponding to the temperature signals;
- and
- a detection structure communicatively connected with the controller for detecting at least one of a current and a voltage of the largest object, wherein at least one of the current and the voltage of the target object is converted to power consumption by the controller, such that the controller adjusts the internal pressure of the cabin based on the power consumption.
