Through the optional implementation mode, the user can be prompted to wear the earphone through detecting the noise degree of the environment where the first device is located, so that the reading effect is guaranteed.
As an alternative implementation, the way for the first device to detect the ambient noise level of the area where the first device is located may be:
the first equipment detects whether a certain wireless access point is accessed currently, and if the certain wireless access point is accessed currently, the first equipment identifies whether the identification information of the wireless access point accessed currently is matched with the identification information of the wireless access point on a certain school bus, which is recorded in advance by the first equipment.
If the information is matched with the information, the first device can consider that the first device is currently located on the school bus, correspondingly, the first device can obtain the identity information of the service device transferred on the school bus, and sends a request message to the service device of the school bus through the wireless access point according to the identity information of the service device on the school bus, wherein the request message carries the identity information of the first device and a request field, and the request field is used for requesting the service device of the school bus to detect the environment noise degree in the school bus.
And the first device acquires the environment noise degree in the school bus, which is sent by the service device of the school bus in response to the request message, and takes the environment noise degree in the school bus as the environment noise degree of the area where the first device is located.
The implementation of the above embodiment can avoid power consumption caused when the first device detects the noisy environment in the region where the first device is located by starting the sensor of the first device, and reduce the heat productivity of the first device caused by aggravation of the power consumption.
Further, after receiving the request message sent by the first device to the service device of the school bus via the wireless access point, the service device of the school bus may further perform the following operations:
the service device of the school bus can identify the user attribute of the first device according to the identity information of the first device carried in the request message, wherein the user attribute can include the user name of the user (such as a student) to which the first device belongs and a curriculum schedule corresponding to the user grade, and the curriculum schedule can include the class time (including date and time) of each subject and the class place of each subject;
the service equipment of the school bus determines the class-taking place of the target subject from the curriculum schedule, wherein the class-taking time of the target subject is closest to the current system time of the service equipment of the school bus;
and when detecting that the school bus runs to the getting-off station corresponding to the class point of the target department, the service equipment of the school bus sends a station arrival notification message to the first equipment through the wireless access point, wherein the notification message comprises the class time and the class point of the target department.
By implementing the embodiment, the user can be prevented from missing the place of class in the process of taking the school bus and listening to the contents to be reported.
