Schematic diagram.Assume that section to be measured has two ports.As it can be seen, gravitometer axial organ 101a and 101b
Being installed in a port of section to be measured, gravitometer axial organ 101c and 101d is installed in section to be measured
Another port.Gravitometer axial organ 101a and 101c can be considered as one group of gravitometer axial organ, and will weight
Power wheel counting apparatus 101b and 101d is considered as another group gravitometer axial organ, and two groups of gravitometer axial organ effects are identical also
And reference each other, to guarantee to export reliable results.Also dependent on needs, one group of gravitometer axial organ is only set
Or arrange more than two groups of gravitometer axial organs.When pressure wheel is at certain gravitometer axial organ, this gravity meter shaft
Device senses that the gravity of vehicle exports the signal of expression wheel process.Enumerator 102a is to from gravity
The signal representing wheel process of wheel counting apparatus 101a and 101c counts, i.e. to through the two gravity
The wheel count of wheel counting apparatus.Such as, if vehicle is from the port being provided with gravitometer axial organ 101a and 101b
Enter this section, leave this section from the port being provided with gravitometer axial organ 101c and 101d, then count
Device 102a can be arranged to add the signal received from gravitometer axial organ 101a counting, and to from
The signal that gravitometer axial organ 101c receives carries out subtracting counting.When count results is 0 (to assume in section
