| titleOfInvention | The measurement mechanism of rock gas gas flow and measuring method |
| abstract | The present invention relates to a kind of measurement mechanism and measuring method of rock gas gas flow.The sensor that the present invention is made up of four thermal resistances and platinum resistance, the sensing circuit be made up of four precision resistances, potentiometer, operational amplifier and triodes, signal amplifier, wave filter and single-chip microcomputer form; Two voltage signals that sensor exports and the voltage signal that sensing circuit exports are connected with the input end of three wave filters respectively after three signal amplifiers, and the output terminal of three wave filters is connected with the AD Sampling Interface of single-chip microcomputer.Structure of the present invention is simple, using four thermal resistances and platinum resistance as sensing element, devises gas flow measurement and angle detecting circuit, adopts constant difference method measurement gas flow.This metering circuit adopts powered battery, can solve the problem that remote districts power supply is inconvenient.Experiment shows, adopt measurement gas of the present invention to respond fast, the response time is less than 10ms, and measurement range is 0 ~ 50m/s. |
