Abstract

The invention provides a three-in-one sensor test system, and the system comprises a test station which is arranged in a case and provided with a test station used for fixing a tested piece; a rotating device which is arranged below the testing station and used for changing the angle of a throttle valve angle sensor of the tested piece; negative pressure equipment which is communicated with the case; and signal acquisition equipment which is arranged on the test station and is used for being electrically connected with the tested piece to acquire a test signal. According to the three-in-one sensor testing system provided by the invention, the calibration and testing of the tested piece are carried out at the testing station, so the situation that the continuity of testing is influenced bymoving the position of the tested piece is avoided; moreover, the rotating device rotates the angular position of the throttle valve sensor while negative pressure is applied, the signal collector synchronously collects signals of a tested piece in the tested piece, data collected under the condition that the negative pressure environment is closer to the actual use condition is more accurate, thedetection is conducted under the conditions that the negative pressure continuously changes and the angle simultaneously changes, and the detection efficiency is improved.

Description

technical field [0001] The application belongs to the technical field of engine throttle three-in-one sensor testing equipment, and in particular relates to a three-in-one sensor testing system and method. Background technique [0002] The three-in-one engine throttle sensor includes a throttle angle sensor, an intake air pressure sensor, and an intake air temperature sensor. Among them, the position sensor knows the different positions of the throttle valve through the different resistance values ​​or voltage values ​​of the variable resistors in the body. The intake pressure sensor is similar to the air flow sensor, and can measure the absolute pressure in the intake pipe according to the load of the engine ( The change of vacuum degree) is converted into a voltage signal and sent to the electronic control unit together with the speed signal. [0003] With the improvement of the production efficiency of motorcycle three-in-one sensors, the calibration and detection method...
