Abstract

This invention discloses a car travel recorder transmitting data by WLAN and its data collection and transmission method, among which, the car terminal is composed of a supply unit, a car signal conversion unit, a MCU, EEPROM, a clock signal unit, a second and receive WLAN unit. The supply provides electricity to all units, the car-loaded signal conversion unit, EEPROM and the clock signal unit connected with the I/O interface of the MCU, the send and receives WLAN data unit is connected with the serial or I/O of the MCU via SPI interface or the serial, which increases data transmission efficiency.

Description

technical field [0001] The invention relates to a vehicle driving recorder, in particular to a vehicle driving recorder which utilizes a wireless local area network to transmit data and a data collection and transmission method thereof. technical background [0002] With the development of the economy, the number of various types of automobiles, private cars, passenger cars, and trucks is increasing, but correspondingly, traffic accidents are also increasing and more frequent. For this reason, the country issued the standard of GB / T19056-2003 "Automobile Driving Recorder" last year, commonly known as the standard of automobile black box. Vehicle driving recorders have been applied in the European Union, Japan and other countries and regions. It can record relevant information of vehicle operation and driver's driving activities in real time within 15 days, and plays an important role in curbing serious traffic violations such as fatigue driving and vehicle speeding, prevent...
