Embodiment 1
[0028] see figure 1 , The vehicle information sensing system of the present invention includes a vehicle-mounted unit (VU), a sensing unit (SU) and an integrated management platform. figure 1 The vehicle-mounted unit 1 to the vehicle-mounted unit n can wirelessly communicate with the sensing unit (SU) arranged on the roadside of the expressway, so that the distributed collection of vehicle data can be realized through the sensing unit (SU). The sensing unit (SU) can communicate with the base station unit it belongs to by wire or wirelessly, figure 1 Including base station unit 1 to base station unit n, each base station unit can communicate with multiple sensing units (SU), figure 1Among them, the sensing unit 1 to the sensing unit n belonging to the base unit 1 communicate with the base unit 1, and the sensing units 1 to L belonging to the base unit n communicate with the base unit n. In addition to communicating with the vehicle-mounted unit (VU) and the base station unit ...
Embodiment 2
[0042] Such as Figure 4 Correspondingly, the present invention also provides a vehicle information sensing method, including the following steps: S100: distributing a plurality of sensing units along the road, forming a wireless ad hoc communication network among the plurality of sensing units, and setting a vehicle-mounted unit in the vehicle; S200: The on-board unit sends vehicle information including at least vehicle identity information to the sensing unit; S300: The sensing unit receives the vehicle information and sends it to the integrated management platform; S400: The integrated management platform obtains the vehicle speed according to the received vehicle information , vehicle location and / or traffic flow information. The step S200 specifically includes reading the card information of the transportation card, and sending the card information as the vehicle identity information to the sensing unit.
