Abstract

The invention relates to fixed supersonic traffic flow investigating equipment which comprises two supersonic probes (1). The two supersonic probes (1) are mounted in the radial direction on each track to be detected, are fixed on a support (2) at the upper end of a road, and are connected with a supersonic detector which is connected with a data transmission terminal, and the data transmission terminal transmits data to a data center through the Internet. The invention overcomes the defects of poor reliability and the like of the prior traffic flow detector and has the advantages of long service life, high detection accuracy, and the like.

Description

technical field [0001] The invention relates to an ultrasonic fixed traffic flow investigation device, which uses the principle of ultrasonic detection, and through the application of computer general technology, realizes the collection of traffic flow information on highways (expressways), bridges, tunnels and special road sections, and truly and effectively reflects Device for traffic flow data. Background technique [0002] Ultrasound has existed in nature for a long time before it became known to humans. Animals such as bats, whales, and dolphins use sonar waves as a guide for positioning. At present, ultrasound has been widely used in industry, navigation, and medical purposes. The application of ultrasound in the intermodulation industry began in Japan. The early analog ultrasonic intermodulation instruments were cumbersome, cumbersome to operate, and there were fewer car types that could be identified; since the emergence of digital ultrasonic systems, the applicati...
