Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for communicating with a vehicle and a communication system control center, and more particularly, to a communication system between vehicles that allows vehicles to communicate with each other and can be connected to a control center.

[0002]

2. Description of the Related Art The global positioning system (hereinafter referred to as "GPS") used in high-end sedan type vehicles is a well-known technology. The system uses a satellite receiver module that simultaneously receives and decodes signals sent to the earth from six satellites to generate a set of coordinates that represent the location of a GPS receiver on the vehicle. This coordinate is sent to the service center via a communication path (such as a mobile telephone network). When the service center receives the coordinates, it provides relevant traffic information, routes or other messages depending on the location of the vehicle and the needs of the user.

[0003] Although manufacturers continue to emphasize the superior performance of GPS, the actual use and implementation of GPS equipment is not as expected. The main reason is that the GPS available to commercial customers is not as accurate as military systems. Therefore, the decoded coordinates received by converting the satellite signal by the GPS receiving module of the vehicle were not completely accurate. Therefore, the coordinates sent to the service center were incorrect. If the initial coordinates sent by the vehicle are already inaccurate as a reference for providing information from the service center, the owner of the vehicle can hardly get an accurate reference message. This is one of the shortcomings of current GPS used in private or commercial vehicles.

[0004] In addition, current vehicle communication systems are used for connection and signaling between vehicles and service centers. There is no effective vehicle-to-vehicle communication using current vehicle communication systems. The driver may, for example, notice situations such as oil leaks or flat tires in the vehicle that the owner did not notice. At present, it is extremely difficult to notify the driver of another vehicle while driving, even if the driver of the other vehicle wants to know.

[0005] In view of the foregoing, current vehicle communication systems have highly technical GPS, but their actual effectiveness is not as expected, and current systems provide for the realization of communication between vehicles. I can't help. It is therefore highly desirable to find an effective solution to the current problem.

The communication receiving device 10 includes a processing device 11, a signal receiving device 12, and a mobile telephone device 13. The processing device 11 has a plurality of built-in passcodes associated with license plate numbers of various vehicles. Signal receiving device 12
Is connected to an input terminal of the processing device 11 which receives at least two kinds of coordinate reference signals, converts the coordinate reference signals into coordinates representing the position of the vehicle, and sends the coordinates to the processing device 11. The mobile telephone device 13 is connected to the control center 20 and the processing device 11 to establish communication with another vehicle provided with the communication receiving device 10A in order to perform two-way communication with the control center 20 and another vehicle. Is done.

Referring to FIG. 2, the processing device 11 includes a micro processor 111, a wired communication unit 112, and a wireless communication unit 113. Microprocessor 111 communicates with signal receiver 12 via a suitable interface.
The wired communication means 112 provides a wired connection between the microprocessor 111 and the mobile telephone device 13. Wireless communication means 1
13 provides a wireless connection between the microprocessor 111 and the mobile telephone device 13. Wired / wireless communication means 112,1
13 is achieved via a multitask processor 114 and a microprocessor 111.

Microprocessor 111 has a plurality of built-in passcodes corresponding to license plates of the corresponding vehicle for communication with communication receiving device 10A of another vehicle. In particular, this passcode can be the number of the mobile telephone device 13 used for the communication receiving device 10 of the specific vehicle. This is set as unspecified by the manufacturer and updated in an appropriate manner.

The microprocessor 111 is connected to the signal receiver 12 via a standard computer RS-232 interface I1.

As the wireless communication means 113, all communication means using wireless signal transmission can be widely applied. In this embodiment, the wireless communication means 113 is a Bluetooth module.

[0017] Bluetooth is a computer-based wireless telecommunications technology developed by Ericsson Inc. of Sweden. In this technique, wireless signals are sent in the 2.45 GHz band. This signal can be a data or voice signal. Bluetooth can be used to establish one-to-one or multiple point-to-point connections. The longest transmission distance is about 10 m. This signal has a large and fast transmission rate (up to 1 megabyte per second) and the transmitted signal is encrypted and immune to electromagnetic interference.

Thus, the processing device 11 communicates with the mobile telephone device 13 via the Bluetooth module. Alternatively, the wireless communication unit 113 can be an infrared module.

Since the microprocessor 111 of the processing device 11 is connected to the mobile telephone device 13 via two communication means at the same time, the microprocessor 111 is connected to the communication means 112,1.
13 is processed using a multitask processor 114.

Referring to FIG. 3, the signal receiving device 12 includes:
It includes a satellite signal receiving module 121, a wireless signal receiving module 122, a coordinate signal converting module 123, and a broadcast module 124. The satellite signal receiving module 121 receives a signal from a GPS satellite. The wireless signal receiving module 122 receives a wireless signal transmitted from the RDS. The coordinate conversion module 123
The PS satellite signal and the radio signal are converted into a set of coordinates.
The broadcast module 124 is connected to the satellite / wireless signal receiving modules 121 and 122. The coordinate conversion module 123 and the broadcast module 124
The multi-task processor 125 is connected to the satellite / wireless signal receiving modules 121 and 122.

The satellite signal receiving module 121 is a conventional GPS satellite receiver and decoder, and will not be described.

Compared to current positioning systems, the signal receiving device 12 has one or more coordinate signal sources, which are radio signal receiving modules 122 for increasing the accuracy of the coordinate signals. The reason is that the satellite signal receiving module 121 simultaneously receives a commercial high-quality satellite signal and a radio signal from the control center. Six sets of satellite signals are received and decoded by the coordinate signal conversion module 123 to generate a set of coordinates, but commercial good signals have an error of up to 100 meters. The radio signal receiving module 122 receives the radio signal sent from the terrestrial base station, and the error generated there is reduced depending on the original accuracy of such a system. Therefore, the coordinates generated by the coordinate signal conversion module 123 based on the satellite signal receiving module 121 and the wireless signal receiving module 122 are effectively increased in accuracy.

The mobile telephone device 13 can be a current mobile telephone. In order to communicate with the processing unit 11 in this embodiment, the mobile telephone has a built-in Bluetooth module for implementing short-range wireless signal transmission.

Referring to FIG. 4, the control center 20 connected to the communication receiving device 10 includes a mobile telephone device 21, a server 22, a broadcast communication device 23, and a display device 24. The mobile telephone device 21 can communicate with each communication receiving device 10. The server 22 provides two-way communication with the mobile telephone device 21 and each communication receiving device 10. The broadcast device 23 is a server 2 for providing a broadcast function.
2 are connected. The display device 24 can be a larger display device connected to the server 22 to display the position of the vehicle.

The above system can operate in a number of forms. When the driver wants to communicate with the driver of a nearby vehicle, the driver simply enters the number of the license plate of the desired vehicle into the communication receiving device 10. If another vehicle is provided with the communication receiving device 10A, the number of the mobile telephone device corresponds to the number of the license plate, and is incorporated in the processing device 11 of all the communication receiving devices 10 and 10A. Therefore, when the driver inputs the number of the license plate of the desired vehicle to the processing device 11, the processing device 11 automatically calls the number of the corresponding mobile telephone device and communicates with the other party via the mobile telephone device 13. The communication with the receiving device 10A is established. The driver then interacts directly with other drivers to seek help, to sort out or remind the situation that is happening.

In the connection between the vehicle and the control center 20, the signal receiver 12 of the communication receiver 10 receives satellite signals and radio signals and converts them into a set of coordinates. The coordinates are sent out and received by the mobile telephone device 21 of the control center 20 via an automatic line connection from the mobile telephone device 13 to the control center 20 by the processing device 11 via the mobile telephone communication network. Thereafter, the signal is sent to the server 22 for processing, and the location of the vehicle is displayed on the display 24.

The server 22 accepts requests made by the driver to provide information services such as relevant road information or route suggestions. The message is sent to the communication receiving device 10 of the vehicle via the mobile telephone communication network. The mobile telephone device 13 of the communication receiving device 10 receives the message and displays (reproduces) the message.

Since the communication receiving device 10 includes the signal receiving device 12 designed specifically, it is possible to generate a highly accurate coordinate signal. The control center 20 can obtain accurate coordinate signals to provide more accurate service to the vehicle.

According to the present invention, the object of providing a communication system with a vehicle and a control center capable of obtaining more accurate coordinates is achieved. Compared with conventional vehicle positioning systems, the present invention effectively solves the problem of large errors in the prior art and provides communication between vehicles that has never been disclosed. It assists in realizing communication between running drivers. Therefore, the present invention has high industrial utility and novelty.

Those having ordinary skill in the art to which the present invention pertains can make various changes and modifications within the scope of the present invention which can be applied to the above specific embodiments and do not depart from the scope of the present invention. Can be recognized.
