Abstract

A system and method for detecting an air leak in a commercial vehicle can detect an air leaked portion of the commercial vehicle using ultrasonic signals measured by a plurality of measurement sensors. The system includes a detection unit for measuring a plurality of ultrasonic signals generated in the commercial vehicle through the plurality of measurement sensors, confirming a position and size of a leak portion where air is leaked based on the plurality of ultrasonic signals to generate sensing data, and generating a photographed image by photographing the commercial vehicle, a management unit for generating a transformed image using a reference value from the sensing data, and a synthesized image by synthesizing the transformed image and the photographed image, and a display unit displaying the synthesized image.

Dependent claims

A system for detecting an air leak in a commercial vehicle, comprising:

a detection unit for measuring a plurality of ultrasonic signals generated in the commercial vehicle through a plurality of measurement sensors, confirming a position and size of a leak portion where air is leaked based on the plurality of ultrasonic signals to generate sensing data, and generating a photographed image by photographing the commercial vehicle;
a management unit for generating a transformed image using a reference value and the sensing data, and a synthesized image by synthesizing the transformed image and the photographed image;
and
a display unit displaying the synthesized image,
wherein the detection unit includes:
the plurality of measurement sensors for measuring the plurality of ultrasonic signals generated in the leak portion;
a camera for photographing the commercial vehicle;
a main board on a front surface of which the plurality of measurement sensors are arranged in a set pattern;
a photographing controller connected to the camera and generating a photographed image photographed through the camera;
a battery for supplying power to the plurality of measurement sensors and the camera;
a measurement controller for generating the sensing data based on the ultrasonic signals collected through the plurality of measurement sensors;
a power supply controller for controlling power supply to the plurality of measurement sensors;
a case having a front receiving portion having a front surface opened to receive the main board and a rear receiving portion connected to the front receiving portion and receiving the photographing controller, the battery, the measurement controller, and the power controller;
a front cover having a plurality of holes corresponding to the camera and the plurality of measurement sensors so that the camera and the plurality of measurement sensors are exposed to the outside;
and
a handle formed on both sides of a rear of the case.

A method for detecting an air leak in a commercial vehicle, comprising:

confirming a barcode data of the commercial vehicle;
measuring a plurality of ultrasonic signals generated in the commercial vehicle through a plurality of measurement sensors after photographing the commercial vehicle to generate a photographed image;
generating sensing data by confirming a position and size of a leak portion where air is leaked based on the plurality of ultrasonic signals measured from the plurality of measurement sensors;
generating a transformed image using a reference value from the sensing data;
synthesizing the transformed image and the photographed image to generate a synthesized image;
and
displaying the synthesized image,
wherein measuring the plurality of ultrasonic signals is performed by the plurality of measurement sensors by photographing the commercial vehicle for each of a plurality of measurement positions while moving by a predetermined distance along the longitudinal direction of the vehicle,
wherein after the measuring step, the method further includes:
confirming a detection result using the sensing data generated for each of the plurality of measurement positions;
generating a result data including detection results matched to each of the plurality of measurement positions;
and
displaying the result data, and
wherein generating the result data includes:
determining whether a size data included in the sensing data is greater than or equal to a reference value and is maintained for more than a preset time;
and
generating the result data by determining to be defective if it is determined that the set time is maintained or longer.
