EXHAUST GAS MEASURING INFORMATION PROCESSING APPARATUS, EXHAUST GAS MEASURING SYSTEM, AND RECORDING MEDIUM

摘要

An exhaust gas measuring information processing apparatus of the present invention detects troubles etc. of a flow sensor during a flow rate measurement and performs predetermined processing relevant to maintenance and check of the flow sensor. The exhaust gas measuring information processing apparatus includes a reception circuit that receives a flow rate measurement signal indicating a flow rate measurement value of exhaust gas flowing through an exhaust gas tube of an internal combustion engine and an operational state signal indicating an operational state of the internal combustion engine, and a processing executing circuit that executes predetermined processing relevant to maintenance and check of the flow sensor that outputs the flow rate measurement signal when a predetermined correlation is not satisfied between an index value for the operational state indicated by the operational state signal and the flow rate measurement value indicated by the flow rate measurement signal.
