METHOD AND DEVICE FOR CONTROLLING TIRES Russian patent published in 2020 - IPC G01M17/02 

FIELD: transport machine building.

SUBSTANCE: present invention relates to automotive tire inspection device. Device comprises: detection system (104), which comprises chamber (105) having optical plane (107) passing through chamber (105), and defining focal plane (121); first light source (110), second light source (108) and third light source (109) configured to emit the first, second and third light radiation respectively to illuminate the surface area of the above tire, located in or near focal plane (121). Second light source (108) and third light source (109) are located on opposite sides relative to optical plane (107). First light source (110) is fixed relative to detection system (104). Second light source (108) and third light source (109) are configured to move from first inactive configuration, in which they are controlled so that they do not emit the second light radiation and the third light radiation, and wherein distance (d2, d3) from second light source (108) and from third light source (109) to focal plane (121) is greater than distance (d1) from first light source (110) to focal plane (121), into active configuration, in which they are adapted for radiation of at least one of second light radiation and third light radiation and in which distance (d2, d3) from second light source (108) and from third light source (109) to focal plane (121) is equal to distance (d1) or less than distance (d1) from first light source (110) to focal plane (121). There is also drive and control unit (140) configured to actuate detection system (104) to obtain a first image and, at least, second image of first surface area and second surface of tire (200), respectively, in inactive configuration and with active configuration.

EFFECT: technical result is improved quality of tire control.
