The communication signal using the set channel is received by the wireless LAN BOX 7. The wireless LAN BOX 7 that has received the communication signal from the access point 9 sets the channel used for transmitting the communication signal to the access point 9 to the channel used for transmitting the communication signal received from the access point 9.

Therefore, based on the signal strength of the communication signal actually received by the wireless LAN BOX 7, the channel through which the wireless LAN BOX 7 can communicate with the access point 9 in a good communication state is determined, and the communication setting between the wireless LAN BOX 7 and the access point 9 is set. It can be reflected.

In this embodiment, the vehicle operation information management system 1 that transmits the operation information of the taxi vehicle 3 collected by the taxi meter 5 from the wireless LANBOX 7 to the operation information analysis device 13 of the center 11 via the access point 9 is taken as an example. I took it and explained it.

However, the present invention can also be applied to an operation information management system that transmits operation information collected by a rent meter other than the taxi meter 5 to the center side by wireless LAN.

Specifically, for example, the operation information related to the driving agency vehicle and the driving agency collected by the agency fee meter mounted on the accompanying vehicle in order to calculate the driving agency fee by the driving agency is transmitted via the access point via the wireless LAN. The present invention can also be applied to a vehicle operation information management system that transmits to an operation information analysis device of a center that manages operation information of a driving agency.

In addition, instead of a rent meter like the taxi meter 5, a single-function operation information collection device that collects operation information generated by the vehicle is connected to the operation information analysis device of the center via an access point via wireless LAN. The present invention can also be applied to a vehicle operation information management system for transmitting.

The present invention is extremely useful when applied to an operation information management system that transmits operation information collected by a vehicle operation information collecting device to an operation information analysis device of a center via an access point via a wireless LAN.
