Abstract

The invention discloses an air inlet heating system fault diagnosis method. The method comprises the steps of receiving collected actual working parameters of an air inlet heater at present working state in present working circulation; comparing the actual working parameters with standard working parameters of the air inlet heater at the present working state, and obtaining a comparison result; judging whether the comparison result meets the requirement of the air inlet heater for normal working at the present working state; and analyzing the type of failure of the air inlet heating system according to the comparison result if the comparison result does not meet the requirement. Correspondingly, the invention discloses an air inlet heating system fault diagnosis system. The method comprises the step of analyzing what kind of failure occurs on which part of the air inlet heating system according to the obtained comparison result so as to realize failure self-diagnosing function of the air inlet heating system.

Description

technical field [0001] The invention relates to automatic control technology, in particular to a fault diagnosis method, controller and system of an intake air heating system. Background technique [0002] In winter, the engine air intake heating system is very important for engine starting. The intake heating system consists of three parts: relay, intake heater and control system. The relay controls the on-off of the intake heater. If the relay fails and causes the intake heater to be normally on, then long-term heating will cause the intake heater to The temperature rises rapidly, which may cause a fire hazard, so it is very necessary to assess the reliability of the intake heating system. [0003] In practical applications, the intake heater generally has 4 working states, and the 4 working states have a fixed sequence, that is, the intake heater must first enter the preheating state, and then enter the pause state, post-heating state, and cooling state in sequence. The...
