[0004] Virtual traffic lights rely on the shared location information of vehicles equipped with corresponding maps. Currently, there are many types of maps on the market, and information interaction is not possible, resulting in a small sample size of location information in each map, which inevitably leads to large errors in traffic light display. Summary of the invention

[0007] Preferably, the criterion for removing duplicate location information is: when the comparison is performed based on the user's registered information and the repetition rate is greater than a set ratio value, the location information is determined to be duplicate information.

[0008] Preferably, the traffic light cloud point information is also corrected according to the received vehicle instantaneous movement information on the road.

[0009] Preferably, the intelligent networked traffic signal light device also includes a vehicle-connected server; the vehicle-connected server is connected to the information interaction center and the vehicle-mounted camera, and feeds back the signal light information collected by the vehicle-mounted camera to the information interaction center; the information interaction center corrects the generated signal light cloud point information based on the collected real-time signal light information.

[0010] Preferably, the vehicle connection server is also used to send signal light damage information to the information exchange center; the information exchange center marks the signal light cloud point information according to the signal light damage information, and reminds the driver of the corresponding damaged signal light to pay attention.

[0011] According to the above technical solution, the intelligent networked traffic signal light device in the present invention can share vehicle location information collected by multiple platforms and obtain more data information, thereby improving the accuracy of the traffic lights displayed on the vehicle map.

[0012] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] See also Figure 1 The intelligent networked traffic light device shown is used to simulate and display traffic light information on a map on a vehicle central control screen, and includes: a plurality of central servers, wherein the plurality of central servers are used to respectively collect information about corresponding vehicles N1 to N2 connected to the network. nThe information exchange center is used to collect the location information of vehicles N1 to N1 from multiple central servers. n The information exchange center learns the signal light alternation time according to the accumulated position information in the specified time period and generates signal light cloud point information; the plurality of central servers are also used to receive the signal light cloud point information generated by the information exchange center and send the signal light cloud point information to other vehicles M1 to M2. n ; Vehicle M1~Vehicle M n The vehicle compares its own location information with the traffic light cloud point information, and displays the nearest traffic light information in the same direction on the map of the vehicle's central control screen.

[0018] The intelligent networked traffic light device can share vehicle location information collected by multiple platforms and obtain more data information to improve the accuracy of the traffic lights displayed on the in-vehicle map. n Different map products are installed in each vehicle, and each map product corresponds to a different central server. The location information collected by each central server is aggregated in the information exchange center, and after deduplication, it is shared with all central servers. In this way, each vehicle M1 to vehicle M n The data information from different platform central servers can be received, making the obtained signal light cloud point information more accurate and rich, and then vehicles M1 to M n By comparing its own location information with the traffic light cloud point information, the nearest traffic light information in the same direction is displayed on the map of the vehicle's central control screen. For example: displaying the traffic light information at the intersection ahead or the next traffic light information in the next route planning.

[0019] In this embodiment, in order to further provide a method for removing duplicate locations, the criteria for removing duplicate location information are as follows: when the repetition rate is greater than a set ratio value, the location information is determined to be duplicate information. For example, the removal ratio value is set to 60%, and the registration information includes name, mobile phone number, address, gender, age, etc. The registration information of the two platforms is fully compared, and the same registration types are compared.

[0020] In this embodiment, the signal light cloud point information is also corrected according to the received vehicle instant movement information on the road. The vehicle instant movement means that when the vehicle is in the starting stage, when the remaining time of the signal light jump differs from the vehicle instant movement time, the signal light cloud point information is corrected.

[0021] In this embodiment, in order to further improve the accuracy of the signal light cloud point information, the intelligent networked traffic signal light device also includes a vehicle-connected server; the vehicle-connected server is connected to the information exchange center and the vehicle-mounted camera, and feeds back the signal light information collected by the vehicle-mounted camera to the information exchange center; the information exchange center corrects the generated signal light cloud point information based on the collected real-time signal light information. The vehicle equipped with the vehicle-mounted camera is connected to the information exchange center through the vehicle-connected server as a medium, and the actual traffic signal information is uploaded to correct the signal light cloud point information.

[0022] In this embodiment, the vehicle connection server is also used to send the signal light damage information to the information exchange center; the information exchange center marks the signal light cloud point information according to the signal light damage information, and reminds the driver of the corresponding damaged signal light to pay attention. Through such a setting, the signal light damage information can be sent to the oncoming vehicle in time, reminding the vehicle to safely slow down and pass the intersection.
