桁架系统的空间位置应对应摄像机缆线的设计位置，因此要求角部自组桁架必须

The spatial position of truss system should respond to the position of the camera cable design, thus requiring the truss from the group corner camera cable must meet the space requirements of the arrangement range of positions. Further, according to its own characteristics truss system requires two fixed truss venue corner space parallel steel beams have linear distance less than 2.4 meters.

The spatial position of the truss system should correspond to the design position of the camera cable, so the angle self-group truss must meet the space placement location range requirements of the camera cable. In addition, according to the truss system's own characteristics, it is required that the two venue angle steel beams fixed with the truss must be parallel to the space and the straight line distance is less than 2.4 meters.

The space position of the truss system should be in accordance with the design position of the camera cable, so the angle self-assembly truss must meet the requirements of the space layout position range of the camera cable. In addition, according to the characteristics of the truss system, it is required that the two corner steel beams fixed with the truss must be parallel in space and the straight-line distance is less than 2.4m.
