in addition, the first reminding module 130 includes: any one or more of a light reminding unit 131, a sound reminding unit 132 and a vibration reminding unit 133.
Specifically, one or more of the light reminding unit 131, the sound reminding unit 132 and the vibration reminding unit 133 may be built in the wireless network card 100. The light reminding unit 131 is connected with the first control module 120, receives the first control signal sent by the first control module 120, and carries out light reminding; the sound reminding unit 132 is connected to the first control module 120, and receives the first control signal sent by the first control module 120 to sound a reminder; the vibration reminding unit 133 is connected to the first control module 120, and receives the first control signal sent by the first control module 120 to carry out vibration reminding. For example, only the vibration reminding unit 133 such as a vibrator is arranged in the wireless network card 100, and when the first communication module 110 receives the search signal sent by the mobile terminal, the wireless network card 100 only carries out vibration reminding through the vibration reminding unit 133.

Here, it is assumed that the preset condition is that the brightness information is equal to or greater than a preset brightness threshold and/or the volume information is equal to or less than a preset volume threshold. For example, the determination unit 122 determines whether the luminance information is equal to or greater than a preset luminance threshold value, and determines whether the volume information is equal to or less than a preset volume threshold value.
When the brightness information is less than the preset brightness threshold (brightness value of sky brightness) and the volume information is less than or equal to the preset volume threshold (volume value of silence), in this scenario, it is dark and the volume of the surrounding environment is small, the generating unit 123 generates the first control signal, which may be sent to any one or more of the light reminding unit 131, the sound reminding unit 132, and the vibration reminding unit 133. Here, when the weather is dark and the noise is low, it is preferable to perform the warning by using a light.
When the brightness information is greater than or equal to the preset brightness threshold and the volume information is less than or equal to the preset volume threshold, under the circumstance that the scene is bright and the volume of the surrounding environment is small, the generating unit 123 generates the first control signal, and the first control signal may be sent to any one or more of the light reminding unit 131, the sound reminding unit 132 and the vibration reminding unit 133. Here, when it is bright and the noise is small, it is preferable to perform the warning by using a sound.
When the brightness information is greater than or equal to the preset brightness threshold and the volume information is greater than the preset volume threshold, under the circumstance that the scene is bright and the volume of the surrounding environment is large, the generating unit 123 generates the first control signal, and the first control signal may be sent to any one or more of the light reminding unit 131, the sound reminding unit 132 and the vibration reminding unit 133. Here, when it is bright and noisy, it is preferable to perform the warning by using vibration.

In this embodiment, specific azimuth information is obtained through calculation, if a plurality of mobile terminals send search signals, and bluetooth communication interaction between the plurality of mobile terminals and the wireless network card 100 is used, direction information of the wireless network card 100 can be determined more accurately, and most typically, a three-point positioning principle is used, that is, the distance between an unknown point (the wireless network card 100) and a known point (a mobile terminal) is known, the unknown point is necessarily located on a sphere with the known point as a sphere center and the distance as a radius, and the distances between the unknown point and three known points are measured, so that the unknown point is located at an intersection of three sphere circumferences (when two points are located, one point located on the back of a receiving plane can be omitted due to a receiving direction), and thus the position of the unknown point is accurately measured. The invention can accurately position, can facilitate the user to more quickly and directly find the wireless network card 100, quickens the searching efficiency and improves the user experience.
Preferably, the method further comprises the following steps: a first judgment module 150; the first determining module 150 is respectively connected to the first communication module 110, the first positioning module 140 and the first reminding module 130;

the first prompting module 130 further generates second prompting information when the first determining module 150 determines that the wireless network card 100 and the mobile terminal are in a disconnected state and the direction information is outside the preset area range.
Specifically, in this embodiment, after the wireless network card 100 is connected to the mobile terminal, if the wireless network card 100 is disconnected from the mobile terminal, the user may forget the wireless network card 100, and at this time, it may be further determined whether the azimuth information between the wireless network card 100 and the mobile terminal is within the preset area range, and if so, the disconnection between the wireless network card 100 and the mobile terminal may occur due to a bad signal of the wireless network card 100 or a network interruption of the wireless network card 100. If not, the wireless network card 100 is forgotten by the user, so that second reminding information is generated to remind the user to return to the placement area of the wireless network card 100 to retrieve the wireless network card 100. Certainly, it may be that the user only temporarily puts the wireless network card 100 aside in some cases, and then further determines whether the time for continuous disconnection reaches the preset time length, and if so, it can be further determined that the wireless network card 100 is forgotten by the user, so as to generate a second reminding message to remind the user to return to the placement area of the wireless network card 100 to retrieve the wireless network card 100. The invention can quickly find the lost wireless network card 100 and give a prompt when the user forgets to take the wireless network card 100, thus being simple and safe.
