Title:
NTC TEMPERATURE MEASUREMENT CIRCUIT, VENTILATOR AND VENTILATOR POWER ON SELF-INSPECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/174674
Kind Code:
A1
Abstract:
An NTC temperature measurement circuit, a ventilator, and a ventilator power on self-inspection method. The NTC temperature measurement circuit comprises: a temperature measurement module (100), a switch module (200), a control module (300), and an inspection module (400); the control module (300) is separately electrically connected to the temperature measurement module (100), the inspection module (400), and the switch module (200); the switch module (200) is separately electrically connected to the temperature measurement module (100) and the inspection module (400); the temperature measurement module (100) is used for monitoring the temperature of a measured part in a heating loop and obtaining first temperature data; the switch module (200) is used for switching on and off power between same and the temperature measurement module (100) and the inspection module (400) according to an enable signal output by the control module (300); the inspection module (400) is used for checking the temperature of the temperature measurement circuit and obtaining second temperature data; and the control module (300) is used for acquiring the first temperature data and adjusting the temperature of the measured part in the heating loop according to the first temperature data, and is also used for obtaining the second temperature data and determining temperature measurement accuracy according to the second temperature data. Power on self-inspection is implemented, temperature measurement accuracy is ensured, and inspection costs are reduced.
