Described keyboard comprises following button: reset key, measure strong, storage key, display key, run-out key and clear key.Can select test density, temperature and demonstration as requested, also can select measurement result memory, output.
The course of work of the present utility model: when measuring fluid density, vibrate density sensor and temperature sensor collection liquid density signal and temperature signal, and signal conveys is arrived the AD modular converter.The AD modular converter is realized the digital-to-analog conversion of sensor signal, the signal after the conversion is passed to single-chip microcomputer handle.Single-chip microcomputer is revised the density of measuring according to fluid temperature, then the result is exported by display.
Fig. 2 is a workflow of the present utility model, and its workflow is as follows:
When (1) installing work, system at first carries out self check, normally then enters " measure and wait for " state as all.The cycle detection temperature is 200 times under this state, about 5min.Press if any key during this period, then change correspondent button function service subprogram over to, press, then follow auto stop after 200 temperature of inspection as no key;
(2) start measuring process by " measurement key ", fluid temperature, density are measured, single-chip microcomputer accounting temperature, density value are gone forward side by side after the trip temperature correction, the display density value.
(3) density measurements is selected to preserve by " storage key "; The measured value of being preserved is in roll display after " display key "; Export by serial port communication by " run-out key " back; By " clear key " full scale clearance.
The electronic devices and components that the utility model adopts are known product, and those skilled in the art are according to the i.e. concrete connected mode of electronic devices and components as can be known of the technical solution of the utility model.
