Embodiment
Below in conjunction with accompanying drawing citing, the present invention is described in more detail:
Based on a portable velocity meter for C8051 single-chip microcomputer, its composition comprises amount module two parts of C8051 data memory module and 89C52 speed.
Above-mentioned C8051 data memory module, is using C8051 single-chip microcomputer as core, gathers and store voltage signal,
The amount module of above-mentioned 89C52 speed, velocity survey is converted into the measurement of time by the autotimer function utilizing 89C52 single-chip microcomputer to carry, and then data is sent on 1602LCD liquid crystal display and shows.
The invention of this class, based on measurement high-speed running objects initial transmissions speed this purpose, adopts initial terminating point measuring method, the measurement of speed is converted into the measurement of time.The orbit of surveyed sports equipment arranges the measuring section of multiple continuous known distance, and initial measuring point is set at each measuring section and stops measuring point, each measuring point is arranged a resistance wire arresting net, all arresting nets are together in series ratio of components parallel resistance network.After all preliminary work completes, all devices start is awaited orders, and velocity-measuring system is resetted and prepares, when moving target cuts off first resistance wire barrier through first measuring point, resistance wire ruptures, and will make the saltus step from 12V to 0V of measuring point voltage, as the starting potential signal of this section.In the starting point of each measuring section and terminal, initial sum final voltage signal is set, utilize C8051 single-chip microcomputer to carry 12 A/D and gather initial sum final voltage signal, gather leaping voltage signal with 89C52 single-chip microcomputer simultaneously and utilize timer function to carry out timing, start timing when receiving the saltus step of starting potential signal, when receiving the saltus step of final voltage signal, timing terminates.Meanwhile, gather initial sum final voltage signal with oscillograph, then artificial computing velocity.The digital signal acquiring mouth of design C8051, by the signal storage that collects in high capability flash flash memory.Utilize 89C52 single-chip microcomputer to carry out testing the speed simultaneously and on LCD display speed.
