Method for obtaining real-time weather condition in travel line

Abstract

The invention discloses a method for obtaining real-time weather condition in a travel line. The method comprises the following steps of: obtaining the travel line by means of an automobile navigator, recording administrative regions along the travel line, and calculating the real-time moment when the automobile runs into the corresponding administrative region, and then obtaining the weather forecast at the real-time moment when the automobile runs into the corresponding administrative region by means of WebService service, then displaying the weather forecast on the display screen of the automobile navigator. The method overcomes the technical current situation that the weather information can be only inquired by point by combining the 3G (3-Generation) communication technology, the navigation technology and the WebService technology together; therefore, the users can obtain the weather information at the passing moment in each region along the travel line quickly and efficiently, thereby providing reference for safe driving conveniently.

Description

technical field [0001] The invention relates to the application field of car navigators, in particular to a method and a system for obtaining weather forecast information of various points along a driving route in real time during driving from a current point to a destination in a GPS navigation system. Background technique [0002] Usually, users of traditional car navigators have not yet realized the 3G Internet access function of navigation products, so the services that traditional car navigators can provide to users are very limited. When users are in a vehicle, the vehicle is like an information island. All external contact methods of users can only be realized by dialing mobile phones, listening to radio stations or text messages. After the user sets the navigation destination for the navigator, he can only drive the vehicle to the destination according to the voice command of the navigator. radio stations, or make phone calls, or send text messages, or rely on mobil...

AI Technical Summary

Problems solved by technology

[0003] To sum up, we can conclude that ordinary navigation systems do not have 3G in-vehicle network, and users can only rely on dialing mobile phones, listening to radio stations, surfing the Internet on mobile phones or text messages to inquire about a certain point on the driving route during driving. When you are on a high-speed vehicle, calling, sending text messages, and surfing the Internet with your mobile phone often mean that you will distract the user's attention while driving, which will easily cause traffic accidents and bring safety belts to the user's personal and property safety. It will cause great harm; and this method can only obtain the weather information of a certain point on the driving route. If we want to obtain the weather information of all points on the driving route, we must continue to query and repeat actions, and we have almost no way to accurately predict our vehicles. Approximately when will it arrive at a certain point on the line

Therefore, the real-time information obtained by repeated query actions cannot accurately reflect the weather conditions of the vehicle passing through the area; if the user is not familiar with which areas the route will pass through, then the local weather information when the vehicle passes through the area cannot be obtained
