Abstract: The present disclosure provides a method and system for vehicle driving data collection. The method includes: sending, by a vehicle central processor, a data collection instruction and a synchronization clock signal to each onboard sensor, wherein the data collection instruction is a control signal for the sensor to be turned on or off; converting vehicle driving data and environmental data collected by the onboard sensor into a digital signal, adding a time stamp to the collected vehicle driving data and environmental data, and transmitting uncompressed digital signal to the vehicle central processor through an optical fiber; and synthesizing, by the vehicle central processor, the collected vehicle driving data and environmental data, and synchronizing the collected vehicle driving data and environmental data according to the time stamp, to obtain a driving state of the vehicle.

Abstract: A wearable device comprises a body (1) and an outer casing (2) detachably mounted on the body (1). The body (1) is provided therein with a first printed circuit board (PCB) and a body antenna connected to each other, and the first PCB is provided thereon with a control circuit. The outer casing (2) is provided thereon with an outer casing antenna (201), and when the outer casing (2) and the body (1) are assembled, the outer casing antenna (201) is connected to the first PCB. The control circuit controls switching between the outer casing antenna (201) and the body antenna to use the outer casing antenna (201) or the body antenna as a working antenna. Also provided are an outer casing and a method for controlling an antenna of a wearable device.
