Abstract

The invention relates to a method for simulating NTC sensor parameters, which comprises the following steps: setting the current temperature value; acquiring the resistance value corresponding to thecurrent temperature value; and controlling a digital potentionmeter to output the resistance value according to the resistance value. The invention also relates to a device for simulating the NTC sensor parameters. The implementation of the method and the device for simulating the NTC sensor parameters have the following beneficial effects: as a resistance regulating unit, a key input unit and a display unit are adopted, and the resistance regulating unit corresponds to the value displayed by the display unit under the control of a control unit, the simulation is more accurate, and the use isconvenient.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for simulating NTC sensor parameters. Background technique [0002] NTC sensor (Negative Temperature Coefficient) refers to a thermistor whose resistance decreases exponentially with temperature rise and has a negative temperature coefficient. It is made by fully mixing, forming and sintering two or more metal oxides such as manganese, copper, silicon, cobalt, iron, nickel and zinc. Usually used as a temperature sensor, etc. In its test circuit, the resistance box is generally used to simulate the change of the NTC sensor, and a certain resistance value corresponds to a temperature (R-T). Temperature changes will produce gaps, which cannot accurately simulate the change in resistance value when the temperature changes. In addition, there is no display interface in the existing simulation device, which is inconvenient to use. Contents of the invention ...
