Automobile travel recorder using radio local network transmitting data and its data collecting and transmitting method

Abstract

The invention discloses a vehicle travel recorder which utilizes a wireless local area network to transmit data and its data collection and transmission method. The vehicle-mounted terminal mainly consists of a power supply unit, a vehicle-mounted signal conversion unit, a microcontroller MCU unit, a large-capacity memory EEPROM and a clock signal unit. , sending and receiving wireless local area network data (WLAN) unit, the power supply unit supplies power to all units, the vehicle signal conversion unit, the large-capacity memory EEPROM and the clock signal unit are all connected to the I / O port of the microcontroller MCU unit, and The sending and receiving wireless local area network data (WLAN) unit is connected with the serial port (or I / O port) of the microcontroller through the SPI port (or serial port). Using this method for data transmission greatly improves the efficiency of data transmission; avoids the mistakes that are easy to occur in the process of human management; and can quickly transmit the driving information of the vehicle to the management center, as long as the vehicle is within the receiving range of the wireless LAN Data can be transmitted within the system, and at the same time, the scope of management can be expanded to achieve more effective management.

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...
