Abstract

The invention discloses a pressure sensor detection system and a pressure sensor detection method. The system is characterized by comprising a master control chip, wherein the master control chip is provided with a first reference input end, a detection input end and a second reference input end; the first reference input end is connected with a first reference pressure sensor; a pressure detection port of the first reference pressure sensor is communicated with the atmosphere; the second reference input end is connected with a second reference pressure sensor; a pressure detection port of the second reference pressure sensor is communicated with a negative pressure source; and the master control chip is connected with an LCD display. The pressure sensor detection system has the advantages of simple structure, low cost, and capacities of finishing accurate detection of static flow and dynamic flow and also meeting the requirements on rapid detection in motorcycle industrialization.

Description

technical field [0001] The invention belongs to the technical field of pressure sensor detection, and in particular relates to a pressure sensor detection system and a detection method for motorcycle pressure sensor detection. Background technique [0002] The pressure sensor is a precision device and an important device of the vehicle EFI system. It is mainly used to monitor the negative pressure value on the engine intake manifold. Through the identification of the negative pressure value, the working condition data of the engine can be obtained. Valve opening and fuel injection volume provide basic reference data. Therefore, the detection of the pressure sensor is very important. Before the pressure sensor is installed on the motorcycle, the performance of the fuel injector needs to be tested, because industrialization requires a fast and efficient testing process. [0003] However, the existing technical means only use a multimeter to detect the output end of the press...
