Abstract

A traffic condition collecting system unitizes at least one traffic condition collecting unit for collecting traffic data and sends the traffic data to the at least one BeiDou satellite. The BeiDou satellite receives the traffic data and transfers it to a traffic information server. The traffic information server generates and accumulates traffic condition information according to traffic data collected by traffic condition collecting units. Therefore, traffic condition collecting units can send traffic data to the traffic information server without other wireless communication modules, thereby generating and accumulating traffic information for use.

Description

Road condition collection system

This creation is about a road collection system, especially a road collection system that uses Beidou satellites to transfer traffic information.

As the number of vehicles increases, traffic flows become larger and larger, and road congestion is more frequent than in the past. Especially during the holiday season or during the peak hours of commuting to work, it is possible to traffic for several hours, which is not only a waste of time, but also a considerable discomfort for the driver and passengers. On the other hand, it is easier for a driver who is in a hurry to reach the destination if he can avoid road jams or bad road conditions. Therefore, the acquisition of traffic information is very important.

Traditionally, the acquisition of traffic information relies on a fixed traffic detector or a user notification system. However, its mobility and timeliness are limited, and the cost of deployment is also high. However, existing vehicle detectors and the like have limited coverage of road condition information transmission (for example, only collecting road conditions in a specific area), or require additional hardware devices for transmission, and cannot be easily and comprehensively collected. Traffic information.

Therefore, how to integrate the existing communication technology and driving road condition data collection system and effectively integrate the application is an important issue at present.

To build demand, use one of the vehicle's road condition collecting devices to collect driving information and return it to Beidou satellite; Beidou satellite forwards the driving information to a road condition information server; the road condition information server can generate a road condition information based on the driving information. In this way, through the return of the traffic information of each user to the Beidou satellite, a comprehensive road condition can be obtained through the integration of the traffic information server.

The traffic collection device includes a first satellite signal transceiver module for receiving at least one positioning signal transmitted by the Beidou satellite and transmitting the driving data to the Beidou satellite; and a signal analysis unit, and the first satellite signal transceiver module The electrical connection is used to calculate a coordinate of the vehicle and a speed data according to the positioning signal, and generate driving information including coordinates and speed data. The traffic information server includes a second satellite signal transceiver module for receiving traffic information transmitted by the Beidou satellite; a database for storing a map data and a road condition information; and a data analysis unit The second satellite signal transceiver module and the data base are electrically connected to generate road condition information according to the driving data and the map data.

The road condition collecting device and the road condition information server of another embodiment of the present invention comprise a road condition collecting system, wherein the road condition collecting device is disposed in at least one vehicle for collecting driving information of the vehicle, and the road condition information server receives the driving data to generate a road condition. News. The traffic collection device includes a satellite signal transceiver module for receiving at least one positioning signal transmitted by the Beidou satellite and transmitting the driving data to the Beidou satellite; and a signal analysis unit electrically connected to the satellite signal transceiver module. It is used to calculate a coordinate of the vehicle and a speed data according to the positioning signal, and generate driving data including coordinates and speed data.

A road condition information server according to another embodiment of the present invention, which is combined with a road condition collecting device to form a road condition collecting device, wherein the road condition collecting device is disposed in at least one vehicle for collecting vehicle driving information including a standard and a speed data.

For example, based on the coordinates in the driving data D and the first map data, the traffic information server 2 can know the road on which the vehicle of the road collecting device 1 is currently being installed, and the speed data can represent the road condition of the road. That is, whether the traffic jam or the speed is too slow. Next, the traffic information server 2 can store the traffic information T in the database 23. Preferably, the data analysis unit 22 can perform statistical analysis on the collected traffic data D to eliminate extreme or abnormal driving data to obtain road information with high reliability. Understandably, the built-in first map data can be continuously updated to respond to changes in road conditions, such as new roads or MRT routes.

In the first embodiment, referring to FIG. 1 , the road information server 2 further includes a road condition broadcast unit 24 electrically connected to the database 23 for transmitting the road condition information T to the second satellite signal transceiver module. 21 is transmitted to the Beidou satellite 3 and then transferred to the road condition collecting device 1. In an embodiment, referring to FIG. 1 , the road condition collecting device 1 further includes an output unit 16 electrically connected to the first satellite signal transceiver module 11 for outputting the first satellite signal transceiver module by sound or video. 11 received road condition information T, for example, the road condition is displayed by the car audio and video system. Understandably, the user can also actively request the required road condition information.

In an embodiment, referring to FIG. 1 , the traffic information server 2 further includes a road condition management unit 25 electrically connected to the database 23 for use according to the usage. The demand of the user provides the road condition information T corresponding to the user, such as a specific road section, a road condition update frequency, a special road condition, etc., and outputs to the road condition broadcasting unit 24. For the purpose of privacy and management, the traffic management unit 25 encodes or encrypts the traffic information T, transmits it to the Beidou satellite 3 through the second satellite signal transceiver module 21, and forwards it to the traffic collection device 1 of each user terminal.

Please refer to FIG. 2. FIG. 2 is a schematic diagram of a road condition collecting system according to another embodiment of the present invention. The operation principle is the same as the foregoing embodiment, and details are not described herein again. The road condition information server 2 includes a road condition broadcast unit 24 electrically connected to the database 23 for directly distributing the road condition information T to the road condition collecting device 1. For example, the road condition broadcast unit can be an FM broadcast system, a wireless communication system, a radio system, a digital television broadcast system, or a combination thereof.

In summary, the present invention provides a road condition collecting system, which utilizes the function of bidirectional short message transmission of Beidou satellite to transfer the driving data collected by the road condition collecting device to the road condition information server, so the road condition information server does not need to Use or re-wire the wireless network or mobile communication network to collect the driving data of the user terminal and generate appropriate traffic information. Preferably, the traffic information server can also use the Beidou satellite to broadcast the road condition information, so that the user of the driving vehicle can understand the immediate road condition. Traffic information can be collected widely and comprehensively, without regional restrictions, and also meets mobility and immediacy. At the same time, it can also provide relative road condition information according to the needs of users.
