The following describes embodiments of the present application in detail.
The embodiment of the application provides an information prompting method and a related product, which can prompt in the driving process and reduce the probability of traffic accidents.
Referring to fig. 1A, an embodiment of the present application provides a flowchart illustrating an information prompting method. Specifically, as shown in fig. 1A, an information prompting method includes:
s101: the electronic device establishes a neighbor induction network NAN connection with a neighbor device.
In the embodiment of the application, both the electronic device and the adjacent device support the NAN function, and both the electronic device and the adjacent device are vehicle-mounted terminals of a corresponding vehicle or are arranged in the vehicle, and the NAN function is turned on before the application is run.
The NAN function may be triggered by similar actions such as turning on a Wi-Fi switch or turning on a button for controlling the NAN function, as shown in fig. 1B, the proximity sensing network and the wired mobile network are in an on state, and the wireless mobile network is in an off state; and the system can also be automatically started when the operation parameters meet certain conditions, wherein: the operating parameter may be a current location of the electronic device, for example: parking area, market, highway etc. the operating parameter also can be electronic equipment's foreground application, for example: applications including location services, applications involving nearby networks, and the like.
Optionally, the method further includes: detecting a moving speed of the electronic device; and when the moving speed meets a preset condition, executing the step of establishing the connection between the electronic equipment and the adjacent equipment through the neighbor induction network NAN.
When the moving speed of the electronic equipment meets the preset condition, the electronic equipment is determined to be in the driving process, and danger is possibly caused to a user, the electronic equipment or a vehicle. The moving speed is relative to the current road section and the congestion situation, and if the moving speed is a high-speed road section, the speed is generally 60km or 80 km; if the traffic jam road section is adopted, the speed is generally 10 km; in the case of a general street, the speed is generally 50km, etc., and is not limited herein.
It can be understood that when the moving speed of the electronic device meets the preset condition, and the electronic device is determined to be in the driving process, the NAN function is started, and NAN connection is established with the adjacent device, so that the driving state of the adjacent vehicle is conveniently determined; otherwise, the NAN function is not started, power consumption can be saved, and the connection accuracy of the NAN and the safety of the electronic equipment and the corresponding user and vehicle can be improved.
The method for detecting the moving speed of the electronic equipment is not limited, and the method can be used for detecting based on a triaxial acceleration sensor in the electronic equipment, wherein the triaxial acceleration sensor has the characteristics of small size and light weight, can measure the space acceleration and is used for measuring the posture and the inclination angle of the electronic equipment.
Referring to fig. 1C, fig. 1C is a schematic diagram of a three-axis acceleration sensor. As shown in fig. 1C, the x-axis, y-axis, and z-axis are all relative to the position of the electronic device body, typically with the y-axis up and the x-axis right and the z-axis perpendicular to the front of the body. The lateral, longitudinal and vertical components are generally projections of a unit of gravitational force (magnitude 1g (m/s), directed vertically downwards) on the respective axes. The horizontal inclination angle is an included angle between an x axis and a horizontal plane, the longitudinal inclination angle is an included angle between a y axis and a vertical plane, and the using posture of the electronic equipment is determined by the horizontal inclination angle, the longitudinal inclination angle and the vertical component.
For example: the method comprises the following steps that the electronic equipment is horizontally placed on a desktop, the x axis is defaulted to 0, the y axis is defaulted to 0, and the z axis is defaulted to 9.81; the electronic equipment is placed on a desktop downwards, and the z axis is-9.81; tilting the electronic equipment to the left, wherein the x axis is a positive value; tilting the electronic equipment to the right, wherein the x axis is a negative value; tilting the electronic equipment upwards, wherein the y axis is a negative value; the electronic equipment is inclined downwards, and the y axis is a positive value; the case that the z-axis is smaller than-3 is considered that the display screen of the electronic device faces downwards.
