Abstract
The invention provides a vehicle flow detection method. The vehicle flow detection method comprises the following steps : step (a), installing an infrared detector on a signal lamp, and when a vehicle passes by, outputting pulse signals; step (b), counting the pulse signals by virtue of a built-in counter of a singlechip, timing the count time by virtue of a built-in timer, and when the count time is over, outputting a count value in the counter; step (c), sending the count value of the singlechip to an upper computer through a wireless network by virtue of a wireless module.
Description
Technical field
The present invention relates to communication technique field, refer to a kind of traffic flow detecting method especially.
Background technology
China has become motor vehicle first country of consumption, the monitoring of road traffic state is become to the important process of traffic control department, and at present, traffic state is monitored in real time mainly through crossing camera, and staff needs real-time monitoring display screen, and work efficiency is low.
Summary of the invention
The present invention proposes a kind of traffic flow detecting method, solves the problem being detected road traffic state in prior art by crossing camera.
Technical scheme of the present invention is achieved in that
A kind of traffic flow detecting method, comprises the following steps:
Step (a), installation infrared detector on signal lamp, output pulse signal when vehicle passes through;
Step (b), counted by the built-in counter pulse signals of single-chip microcomputer, its built-in timer carries out timing to gate time, the count value in timing time then output counter;
Step (c), is sent to host computer by the count value of single-chip microcomputer by wireless network by wireless module.
Alternatively, by GPRS module, the count value of single-chip microcomputer is sent to host computer
The invention has the beneficial effects as follows: by infrared eye inspection vehicle flow, simply rapidly, can directly in host computer display wagon flow data.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the process flow diagram of traffic flow detecting method of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of traffic flow detecting method of the present invention, comprises the following steps: step (a), installation infrared detector on signal lamp, output pulse signal when vehicle passes through; Step (b), counted by the built-in counter pulse signals of single-chip microcomputer, its built-in timer carries out timing to gate time, the count value in timing time then output counter; Step (c), is sent to host computer by the count value of single-chip microcomputer by wireless network by wireless module.
Preferably, by GPRS module, the count value of single-chip microcomputer is sent to host computer
The invention has the beneficial effects as follows: by infrared eye inspection vehicle flow, simply rapidly, can directly in host computer display wagon flow data.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
