Description
The invention discloses a local vehicle guidance system for road construction, and belongs to the field of vehicle road traffic planning
Technical Field
Along with the process of urbanization, the car reserves of china promote by a wide margin, large-scale vehicle pours into the city, the traffic band of giving the city comes huge pressure, and in the city, the construction on road surface also often takes place with the condition of salvageing, the tradition is submitted the construction to intelligent traffic command center by the road administration department and is applied for and mark the mode of construction position in on-vehicle navigation map, be difficult to guarantee in the aspect of the real-time, the crowded phenomenon of road traffic often appears, and, because the needs of city construction, the construction phenomenon of road also frequently takes place, frequent application information also brings pressure for intelligent traffic command center's information processing.
The invention aims to solve the problems that: the method comprises the steps of firstly judging whether a road construction section is in a vehicle peak period state or not, automatically reporting information to an intelligent traffic command center if the road construction section is in the vehicle peak period state, carrying out route planning in a wide area range by the intelligent traffic command center, carrying out local vehicle induction by a system if the road construction section is in an off-peak period state, and ensuring the effectiveness and real-time performance of signal transmission and safe and reliable work if the road construction section is in the local area by the local vehicle induction system.
The scheme adopted by the invention for solving the technical problem is as follows: the transmission and the receiving tool of signal adopt bluetooth system, guarantee to use bluetooth transmitter as the center, and the bluetooth receiver of radius 300 meters within ranges can effectual receipt and transmission information, and the bluetooth transmitter on the road construction sign has the function of transmitting signal and statistics connected equipment figure. The vehicle-mounted Bluetooth annunciator has the functions of receiving signals sent by the Bluetooth transmitter, continuously transmitting the signals to the 300-meter range taking the vehicle as the center, and continuously transmitting construction position information, so that the size of the local range and the effectiveness of signal transmission in the range are ensured. The Bluetooth emitter on the road construction indicating plate counts the number of vehicles directly and indirectly receiving the sent signals, the judgment is carried out by the judgment module, and if the number n of the vehicles is more than the set number n0Reporting the information to the intelligent traffic command center, planning and allocating the path in the wide area range by the intelligent traffic command center, and if the number n of vehicles is less than the set number n0Then the system performs vehicle induction in the local area.
The present technique has the following advantages
1. Whether the peak period is reached or not can be reasonably judged in real time, and the wide area mode and the local mode are selected.
2, the connection between the vehicles in the local area and the construction direction board can be established in real time, the path of the vehicles can be planned more rapidly, and the time lag problem caused by the report of the administrative department and the intelligent traffic command center in the traditional mode is solved.
3. The dual-function characteristic of the Bluetooth annunciator can be utilized to establish the contact between the vehicle and the vehicle, and the problem of limited transmission distance of the Bluetooth device is solved.
4. The invention has simple structure, only installs the control module and the sensor on the traditional road construction sign and the traditional vehicle navigation system, and does not influence the original purpose of the system while expanding the function.
5. The invention only needs the participation of the intelligent traffic guidance center in the peak period, and relieves the pressure of the intelligent traffic guidance center on processing a large amount of information.
Fig. 1 is a schematic structural diagram of a local vehicle guidance system for road construction.
Detailed Description
The following further describes the specific implementation process of the present invention with reference to the attached drawings:
fig. 1 is a schematic structural diagram of a local vehicle guidance system for road construction. When a road is to be constructed, a construction indication board with a Bluetooth signal emitter and a judgment module is placed at a proper position, the Bluetooth emitter is started, a vehicle 1 which is provided with the Bluetooth annunciator in a Bluetooth local area range receives a signal emitted by the Bluetooth signal emitter, the Bluetooth annunciator transmits the position information (namely construction position information) of the Bluetooth emitter to a vehicle-mounted navigation system, the construction position is marked out in a vehicle-mounted navigation map and path planning is carried out again, meanwhile, the Bluetooth annunciator of the vehicle 1 carries out local transmission on the received construction position information, the Bluetooth emitter of the vehicle 2 in the transmission range receives the construction position information emitted by the vehicle 1, and the construction position information is continuously transmitted while the information is transferred to the vehicle-mounted navigation system and the path planning is carried out. In the whole local area range, n automobiles receive construction information. The Bluetooth signal transmitter transmits the number of the vehicles receiving the construction signal position to the judgment module in real time. If the number n of vehicles is less than the set number n0Then continuing to carry out local vehicle induction; if the number n of vehicles is greater than the set number n0And reporting the construction information to an intelligent transportation command center (ITS), and planning the paths of all vehicles in a wide area range by the ITS, wherein the priority is higher than that in the case of a local area range. The local vehicle guidance system for road construction can be used for more efficiently and timely guiding vehicles in a local range, and can be used for more effectively preventing the traffic jam phenomenon caused by road construction.
