Exemplary embodiments of the invention are described with reference to the accompanying drawings, in which:
FIG. 1 is a functional block diagram of a smart indicator according to the present invention.
Fig. 2 is a functional block diagram of an electronic map updating system according to the present invention.
The drawings are only schematic and show only those parts which are necessary in order to clarify the invention, other parts being omitted or merely mentioned. That is, the present invention may include other components in addition to those shown in the drawings.
Detailed Description
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, the intelligent indicator of the present invention generally comprises a positioning module, an information module and a transmitting module. The positioning module is used for acquiring the geographical position information of the intelligent indicator so as to determine the position of the intelligent indicator; the information module is used for setting, storing or acquiring information adaptive to the function of the intelligent indicator; the transmitting module is used for transmitting corresponding information.
Alternatively, as a modification of this embodiment, the positioning module may not be included, and the positional information of its placement may be manually set in the information module.
As a further variation of this embodiment, a receiving module may also be included for receiving information from the outside world. The receiving module can receive information from the outside and store the information in the information module.
As specific examples of the smart indicator, it includes, but is not limited to, the following categories:
intelligent roadblock: the device can be an intelligent device with positioning and wireless communication functions, when road construction or traffic accidents occur, the device is placed on a corresponding road section, so that the position information and the types of roadblocks (namely road construction, traffic accidents and the like) are updated to an electronic map in real time, and a driver or an automatic driving vehicle is reminded of taking detour decisions at any time. Additionally, the device may be timed, either locally or through a remote server, to indicate the approximate time at which the barrier is about to be cleared, thereby informing the driver or autonomous vehicle of more information.
Intelligent parking signpost: for parking space signs with time definition, no information about time is available in current electronic maps. After the intelligent indicating sign with positioning and wireless communication functions is adopted, the time information can be automatically synchronized to the electronic map, and the limited time can be changed at any time in a local or remote mode according to the specific situation of the parking lot and synchronized to the electronic map, so that a driver or an automatic driving vehicle can master more parking information. In addition, although the current electronic map can recommend a parking lot near the end of the navigation route, the number of remaining parking spaces in the parking lot cannot be acquired, and therefore, the situation that the parking space is full when the electronic map arrives at the parking lot recommended by navigation is often found. When the intelligent parking sign board is adopted, the intelligent parking sign board can send time limit information, and can also send information of the rest parking spaces to an electronic map, so that path planning is optimized.
Intelligence time limit highway section denoter: many road sections have a signboard limiting the passing time, for example, the road cannot turn left or turn around in a specified time period, and the current electronic map has no specific time information limiting the passing time signboard, and when a driver arrives at the intersection, the driver can easily change the driving track temporarily due to suddenly seeing the signboard, thereby causing an accident. By placing the intelligent indicator mark of the invention on the corresponding road section, the time-limited information can be synchronized into the electronic map, and the limited time can be changed at any time in a local or remote mode according to the current road condition and synchronized into the map, so that a driver or an automatic driving vehicle can know the time-limited traffic condition of the road section to be traveled in advance and consider the time-limited traffic condition when planning the path.
Intelligent ETC sign: the ETC sign of the expressway is set to be the intelligent traffic sign electronic equipment based on the Internet of things, when ETC channels change, a remote computer can issue and set which channels are ETC, so that the channels do not need to be identified by naked eyes for human driving, and the channels do not need to be identified by a camera for an automatic driving vehicle, so that drivers and the automatic driving vehicle can obtain more real-time information.
Intelligent speed limit sign: the road speed limit sign is replaced by intelligent traffic sign electronic equipment based on the Internet of things, when the road is congested, the adjusted speed information can be sent to the intelligent speed limit sign through a remote computer, and the intelligent speed limit sign receives the information through a built-in receiver, so that the speed limit condition of each road section is allocated in real time. The specific allocation strategy can adopt some optimization algorithm strategies, and the allocation is not needed by people, and the speed modification needs to set upper and lower limits according to the attribute of the road, which is not described herein again.
The structure and some specific examples of the smart indicator of the present invention have been described above. The intelligent electronic map updating system of the present invention will be described with reference to fig. 2.
Referring to fig. 2, the intelligent electronic map updating system of the present invention includes a plurality of intelligent indicators, a cloud server, and an electronic map back-end server. The intelligent indication mark sends related information to the cloud server through the emitter of the intelligent indication mark, and then the cloud server sends the information to the electronic map rear-end server, so that real-time updating of all data is achieved.
Obviously, in the embodiment shown in fig. 2, the cloud server may not be included, and the intelligent indicator may directly send the information to the server of the electronic map itself. Or the cloud server is a component of the electronic map.
Furthermore, outdated or erroneous information in the intelligent indicator can be corrected by a worker in charge of maintaining the electronic map or a user who is given corresponding authority. Alternatively or additionally, the information in the electronic map may be corrected directly without altering the information in the smart signage. Alternatively, the parameter of the intelligent indicator can be set locally or remotely.
When the system according to the invention is used for updating the electronic map, a driver or an automatic driving vehicle can master more information, so that traffic transportation is more smooth, safe and efficient.
The foregoing description is only exemplary of the principles and spirit of the invention. It will be appreciated by those skilled in the art that changes may be made in the described examples without departing from the principles and spirit thereof, and that such changes are contemplated by the inventors and are within the scope of the invention as defined in the appended claims.
