Five, embodiment:
The present invention's first and second alcohol (octane value) gasoline tester is on octane value detector basis, for the detection of satisfying methanol and ethanol gasoline content is researched and developed.Referring to Fig. 1, controller comprises single-chip microcomputer, and single-chip microcomputer is connected with sensor by oscillatory circuit, is connected with giant-screen Chinese display device, keyboard and stabilized voltage supply on the single-chip microcomputer respectively.Testing circuit of the present invention is divided into the two large divisions, and referring to Fig. 3, first is a sensor circuit, and the major function of this part circuit is to produce the different square-wave signal of frequency, and the variation of frequency is directly proportional with the content of first and second alcohol in the tested methanol and ethanol gasoline.Owing to adopted three jumbo sensors, make the sensitivity of sensor be improved, test is accurately.Common octane value can't detect the gasoline that contains first and second alcohol, and its main cause is: first and second alcohol have electric conductivity preferably, thereby cause the methanol and ethanol gasoline conductance to increase, and make common octane value detector oscillatory circuit failure of oscillation to detect.This instrument adopts sensor and fixed capacity to be in series, and makes oscillatory circuit energy operate as normal, and sensor can convert the gasoline that contains first and second alcohol to the square-wave signal of different frequency accurately, and this square-wave signal is delivered to ultra low-power microcontroller MSP430F135 and handled.Referring to Fig. 4, sensor is three high capacity sensors, comprises base, and base is provided with outer jacket casing, is middle sleeve in the outer jacket casing, is inner sleeve in the middle sleeve, is temp probe in the inner sleeve.Referring to Fig. 2, second portion is the MSP430F135 Single Chip Microcomputer (SCM) system.This system's major function is the square-wave signal that sensor is carried, and handles the content that demonstrates first and second alcohol in the tested methanol and ethanol gasoline at last by large-screen lc under the control of testing software.This instrument also has touch keyboard and interface circuit in addition.The function of keyboard is to manipulate instrument, selects different types of gasoline.Interface circuit can be realized this instrument and peripherals such as printer, and computer link realizes that data transmit and handle.
Referring to Fig. 4, sensor is three high capacity sensors, comprises base 5, and base 5 is provided with outer jacket casing 1, is middle sleeve 2 in the outer jacket casing 1, is inner sleeve 3 in the middle sleeve 2, is temp probe 4 in the inner sleeve 3.
Referring to Fig. 5, Fig. 5 is a software program flow chart of the present invention.
