The second main antenna, the first sub-antenna, the second sub-antenna, and the special antenna are perpendicular to the antenna waterproof pad in the horizontal direction, and the first sub-antenna, the second sub-antenna, and the special antenna are parallel to each other.

[0009] Further, the housing is divided into an upper housing and a lower housing. The antenna waterproof pad is fixedly connected to the lower housing. The information collection device is fixed on the inner wall of the upper housing through the fixing bracket. The upper housing is provided with a through hole for the information collection device to pass through.
