a vehicle body having an inspection arm support to support an inspection arm,

the inspection arm including a cross arm and a vertical arm to define an L-shape that is deployed in use to define an inspection tunnel in which an object to be inspected is placed,

the cross arm having the first inspection device and the second inspection device,

the first inspection device is arranged on an end of the cross arm positioned to enable identification of potential collisions with the vehicle body and the second inspection device is arranged on an opposite end of the cross arm positioned to enable identification of potential collisions with the vertical arm, a distance between the first inspection device and the vehicle body is smaller than a distance between the second inspection device and the vehicle body, and a distance between the second inspection device and the vertical arm is smaller than a distance between the first inspection device and the vertical arm,

the controller configured to output four output points to control the first inspection device via four input points for selecting a coverage area of the first inspection device, the coverage area and the position of the first inspection device defining a first laser inspection plane, the first inspection device being configured to emit a laser by way of a circular scanning according to the four output points received from the controller, the first laser inspection plane being parallel to the vehicle body, and a length of the longest portion of the first laser inspection plane being longer than a length of the vehicle body, the emitted laser by way of the circular scanning being adjustable by the four input points to scan objects of irregular shapes; and

the controller configured to output four output points to control the second inspection device via four input points for selecting a coverage area of the second inspection device, the coverage area and the position of the second inspection device defining a second laser inspection plane, the second inspection device being configured to emit a laser by way of a circular scanning according to the four output points received from the controller, the second laser inspection plane being parallel to the vehicle body, and the second laser inspection plane being centered on the cross arm, and extending a first preset distance and a second preset distance forward and backward of the cross arm, the emitted laser by way of the circular scanning being adjustable by the four input points to scan objects of irregular shapes,

wherein the object is at least between the first laser inspection plane and the second laser inspection plane, at least one of the first inspection device and the second inspection device is configured to issue an alarm signal when the respective at least one of first inspection device and the second inspection device inspects an object exceeding a preset size,

wherein the first laser inspection plane is divided into a first inspection region and a second inspection region adjacent to each other, the first inspection region being closest to the rear of the vehicle body, wherein the first inspection device is configured to issue the alarm signal which comprises at least one of a first alarm signal and a second alarm signal, when the first inspection device inspects the object in the first inspection region, the first inspection device is configured to issue the first alarm signal corresponding to the first inspection region and the second inspection region based on the inspection, when the first inspection device inspects the object in the second inspection region, the first inspection device is configured to issue the second alarm signal corresponding to the second inspection region based on the inspection.

2. The system according to claim 1, wherein

the controller is configured to stop the movement of the vehicle body when the alarm signal from the at least one of the first inspection device and the second inspection device is received.

3. The system according to claim 1, wherein the first laser inspection plane is divided into a plurality of inspection regions, including the first inspection region, the second inspection region and a third inspection region adjacent to the second region, wherein the first inspection device is configured to issue the alarm signal which comprises at least one of a first alarm signal, a second alarm signal and a third alarm signal;

when the first inspection device inspects the object in the first inspection region, the first inspection device is configured to issue the first alarm signal corresponding to each of the plurality of inspection regions based on the inspection;

when the first inspection device inspects the object in the second inspection region, the first inspection device is configured to issue the second alarm signal corresponding to each of the plurality of inspection regions other than the first inspection region based on the inspection;

when the first inspection device inspects the object in the third inspection region, the first inspection device is configured to issue the third alarm signal corresponding to each of the plurality of inspection regions other than the first inspection region and the second inspection region based on the inspection.

4. The system according to claim 1, wherein the coverage area for the first inspection device and the second inspection device are set according to user settings.

5. The system according to claim 4, wherein the first inspection device and the second inspection device are connected to an electronic equipment network, and receive the user settings transmitted by the electronic equipment.

6. The system according to claim 1, wherein the first inspection device and the second inspection device are both regional laser scanners.
