Abstract
The invention relates to a tail gas after-treatment real-time monitoring system. The tail gas after-treatment real-time monitoring system comprises a sensor layer, a driving layer, a signal processing layer, a CAN communication layer, a strategy laye, a wireless display screen and a ZigBee communication protocol, wherein the sensor layer is responsible for acquiring sensor signals as a decision basis of the strategy layer, the driving layer is used for ensuring stable transmission of signals in a hardware layer, the signal processing layer is used for processing digital signals and analog signals for the strategy layer to use, the CAN communication layer is used for ensuring that signals are stably transmitted and received on a CAN bus, each decision module of DOC, DPF and SCR adopts a model-based method to realize recognition, feedback and decision of a post-processing system state according to the signals of the sensor layer and the signals processed by the signal processing layer, the wireless display screen is used for displaying real-time information and giving an alarm for abnormal information. According to the tail gas after-treatment real-time monitoring system, aiming at the post-processing transformation vehicle, especially the national III vehicle without a OBD system, the state of the post-processing system of the vehicle can be prompted in real time, and if a fault occurs, a driver can be prompted to carry out overhaul, maintenance, replacement and the like in time.
