Embodiment Construction

[0065] In order to better explain the present invention and facilitate understanding, the present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0066] see figure 1 , the data recorder of the present invention, the whole circuit is made up of ARM processor, K line and CAN circuit, 3G module circuit, data storage module, WIFI module, data acquisition circuit, acceleration module circuit and power supply circuit, and other auxiliary circuits.

[0067] Wherein, the ARM processor of the present embodiment uses the Italian-French ARM processor, and the circuit is as figure 2 shown. The circuit includes IO ports connected to each block circuit and the circuit of the processor. The processor uses two crystal oscillators, the main crystal oscillator and the clock crystal oscillator. IO is used to control the three-stage tube to drive the buzzer. There are multiple decoupling circuits in the circuit. capacitanc...

Abstract

The invention relates to a data recorder, and solves the problems that a calibration engineer needs to drive for data acquisition, that is, the calibration engineer has to be a driver while acquiring data, burst data and undesirable phenomena cannot be judged in real time, the updated ECU (Electronic Control Unit) programs cannot be modified immediately, and abrupt phenomena cannot be handled promptly. The data recorder is characterized by comprising a processor, a data acquisition interface circuit and a communication circuit, wherein the data acquisition interface circuit is connected and communicates with the processor and is provides with a power supply interface; the communication circuit is connected and communicates with the processor, and provides with a 3G/4G network to communicate with the outside. The invention also relates to a remote program updating system and an application method thereof. Data can be remotely acquired and transmitted at a high speed to a server to be stored, and the calibration engineer can observe the data in the background in real time to judge the appearing data in real time so as to judge and detect the running state of an ECU and can also modify ECU programs in real time in case of undesirable phenomena.

Description

technical field [0001] The invention relates to a device for adjusting ECU, in particular to a data recorder capable of remotely adjusting ECU, and a remote flashing system based on the data recorder and an application method of the remote flashing system . Background technique [0002] The electronic control unit (Electronic Control Unit, referred to as ECU) is a comprehensive control device whose function is to provide reference (reference) voltage to each sensor, receive electrical signals input from sensors or other devices, and store the received signals , Calculation and analysis processing, according to the results of calculation and analysis to issue instructions to the executive components. Also known as "driving computer", "vehicle computer", etc., it is usually used as a special microcomputer controller for automobiles. [0003] The ECU program update (or called adjustment, flashing) is produced in the era of electric fuel injection internal combustion engine ve...
