In this way, pedestrians can be asked for help, so that the cyclist can be rescued in time and can avoid secondary injuries.

[0057] Refer to the attached Figure 1 As shown, in some embodiments, the alarm prompt unit 40 includes a second communication module 42, and the second communication module 42 is electrically connected to the main control module 30;

[0058] After generating a first control signal upon receiving tilt abnormality information fed back by the cloud server cluster via the first communication module 20, the main control module 30 calculates the fall duration;

[0059] When the duration of the fall exceeds the first preset threshold, a second control signal is generated, and the second communication module 42 is used to receive the second control signal from the main control module 30, and send a warning SMS to the mobile terminal of the guardian preset by the cloud server cluster according to the second control signal;

[0060] When the duration of the fall exceeds the second preset threshold, a third control signal is generated. The second communication module 42 is used to receive the third control signal from the main control module 30, and establish a communication connection with the mobile terminal of the guardian preset by the cloud server cluster for voice call according to the third control signal.

[0067] According to this embodiment, after the main control module 30 sends the distance to the cloud server cluster via the first communication module 20, the cloud server cluster determines whether the distance exceeds the preset distance threshold. When the distance exceeds the preset distance threshold, the cloud server cluster feeds back the distance abnormality information via the first communication module 20 to enable the main control module 30 to generate a fourth control signal, and then the voice module 41 sounds a warning according to the fourth control signal. In this way, by detecting the distance between the rider and the obstacle, a collision accident can be avoided.

[0068] Refer to the attached Figure 1As shown, in some embodiments, the data acquisition unit 10 includes a speed sensor 13, which is electrically connected to the main control module 30, and the speed sensor 13 is used to detect the riding speed of the rider;

[0069] The main control module 30 is used to send the riding speed to the cloud server cluster via the first communication module 20 and generate a fourth control signal when receiving speed abnormality information fed back by the cloud server cluster via the first communication module 20 .

[0070] According to this embodiment, after the main control module 30 sends the riding speed to the cloud server cluster via the first communication module 20, the cloud server cluster determines whether the riding speed exceeds the preset speed threshold. When the riding speed exceeds the preset speed threshold, the cloud server cluster feeds back the abnormal speed information via the first communication module 20 to enable the main control module 30 to generate a fourth control signal, and then the voice module 41 sounds a warning according to the fourth control signal.

[0076] According to this embodiment, after the main control module 30 sends the light intensity to the cloud server cluster via the first communication module 20, the cloud server cluster determines whether the light intensity exceeds the preset light threshold. When the riding speed exceeds the preset light threshold, the cloud server cluster feeds back the light abnormality information via the first communication module 20 to enable the main control module 30 to generate a fifth control signal, and then the warning light source 44 lights up the warning light according to the fifth control signal. In this way, by detecting the light intensity of the surrounding environment in front, when the light is not good, the warning light source 44 lights up the warning light in time, thereby preventing collision accidents as much as possible.

[0086] According to this embodiment, when the rider falls down, the main control module 30 is in the process of calculating the duration of the fall. The rider sends a stop signal to the main control module 30 by pressing the control button 50, and the main control module 30 stops calculating the duration of the fall according to the stop signal. At the same time, the main control module 30 sends a close broadcast signal to the voice module 41, so that the voice module 41 turns off the voice broadcast according to the close broadcast signal.

[0087] See attached Figures 2 to 4 As shown, in some embodiments, a wearing detection component 60 is included, and the wearing detection component 60 includes a supporting seat 61, a spring 62, a first conductive sheet 63 and a second conductive sheet 64.
