In consideration of safety, if the speed of a vehicle is too high, it is not suitable to connect it to the local area network, so as to avoid danger caused by inattention when the driver performs information interaction through the local area network. In addition, it requires time to connect the vehicle to the local area network. If the speed of the vehicle is too high, the vehicle will quickly pass through the first range covered by the local area network of the street lamp integration device, thus it will be unnecessary for the vehicle to be connected to the local area network of the street lamp integration device. Hence, in one embodiment, the speed of the vehicle is to be detected so as to determine whether the vehicle will be connected to the local area network by assessing the speed. In such a case, the first condition can be set as the speed of the vehicle being smaller than a speed threshold. By determining whether the speed of a vehicle matches the first condition, a vehicle at a too high speed cannot be connected to the local area network.

Specifically, as shown in FIG. 2, the street lamp integration device can further comprise: a detector 106. The detector 106 can be configured for detecting a speed of a vehicle in the first range, and sending the speed of the vehicle to the controller 105. The controller 105 can be configured for, if it is determined that the speed of the vehicle sent by the detector 106 matches the first condition, determining to connect the vehicle to the local area network. Hence, even if a vehicle enters the range of the local area network generated by the street lamp 101, the vehicle will not necessarily be connected to the local area network. The vehicle can be connected to the local area network only when the speed of the vehicle is smaller than the speed threshold.
