Title:
AUTOMOBILE TAIL GAS CONCENTRATION TESTING SYSTEM BASED ON NEURAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2023/221228
Kind Code:
A1
Abstract:
The present invention provides an automobile tail gas concentration testing system based on a neural network, comprising a sensor probe (100), a control module (200), a temperature control circuit (300), a timer module (400), a tail gas concentration potential testing circuit (500), a thermocouple temperature measurement compensation circuit (600), and an analog quantity output circuit (700). The sensor probe (100) is electrically connected to the temperature control circuit (300), the tail gas concentration potential testing circuit (500), and the thermocouple temperature measurement compensation circuit (600); the temperature control circuit (300) is electrically connected to the timer module (400); the timer module (400), the tail gas concentration potential testing circuit (500), and the thermocouple temperature measurement compensation circuit (600) are electrically connected to the control module (200); the control module (200) is connected to the analog quantity output circuit (700). The system in the present application is high in sensitivity, fast in response, good in stability, and high in practicability, and can be widely applied to real-time monitoring of the automobile tail gas concentration.
