With the increase in the number of cars, the probability of traffic accidents increases, and it is difficult to analyze, judge, and maintain the traditional methods after an accident. In this way, people are asked a question, how to analyze the existence of the fault in a timely and prepared manner, and objectively analyze the responsibility of the accident. This is linked to the "black box" on the plane. Once the plane crashes, the information in the "black box" is an important basis for judging the cause of the crash. Because of its high cost and complicated technology, it is difficult to use on ordinary cars. This article describes a low-cost, full-featured and scalable car tachograph. This recorder uses the LPC2104 CPU with ARM7 core as the main control unit, and the large-capacity flash memory as the storage carrier with accurate clock circuit. The high-precision A/D converter is used to collect the analog quantity of the car sensor conversion, and directly Record various types of switches such as car lights. At the same time, the serial port is used to realize data communication with the microcomputer, and the low-level information of the vehicle traveling record is stored in the form of a binary file on the hard disk.
1 system hardware design The overall framework of the system is shown in Figure 1. The LPC2104 CPU with ARM7 core is the core of the vehicle travel recorder. The whole system consists of information acquisition module, information processing and storage module and serial communication module. The LPC2104 is an ARM7TDMI-S CPU from Philips that supports real-time emulation and tracking. It integrates an ARM7 local bus interface to the on-chip memory controller and an AMBA high-performance bus (AHB) and interface chip interfacing with the interrupt controller. Internal peripheral functions of the VLSI peripheral bus (VPB, ARM, AMBA bus compatible VLSI), and embedded 128KB high-speed flash memory. The LPC2104 configures the ARM7TDMI-S as a small-ended (Iittle-endian) byte sequence with small package size, low power consumption, multiple 32-bit timers, multiple bus interfaces, and up to nine external interrupts. The main control CPU of the car tachograph. At the same time, the LPC2104 features a 128-bit wide memory interface and a unique acceleration structure that allows 32-bit code to run at maximum clock frequency. 2 Information acquisition module design The vehicle travel recorder requires real-time recording of various state information of the vehicle. Therefore, the system divides the information acquisition module into a switch data acquisition module, an analog data acquisition module, and a clock data acquisition module.

3.0mm Wire To Board Connectors Advantages
Small electronics with high current requirements
One of the strongest advantage of the Micro Fit series is its applicability in delivering the high current requirement in electronics with supplying high power.
Safe and Reliable
ensure safety, system protection and performance with its bonded metallic conduits and multiple grounding points preventing fire hazards, component damage, overheating and possible electrocution.
ROHS Compliant
The product does not contain restricted chemicals in concentrations not complying with ROHS standards. Thus, for its components, the products can be worked upon at high temperatures required by lead-free soldering.
3.0mm Wire To Board Connectors Application
Motherboard Connectors
The Motherboard of a computer holds together many of the crucial components such as the central processing unit (CPU), memory and connectors for input and output devices. Microfit connectors ensure high performance electronic system in quality motherboards.
You can easily find Scondar`s Microfit in most ITX Motherboards, in which its functionality is best described for solid performance in a small footprint, and low power consumption (less than 100 Watts).
Printer Connectors
The 3.0mm Microfit can also be seen in most printers
Automotive PC Connectors
Smart, high power automotive PC power supply garners its capabilities from quality Microfit connectors, designed for general purpose battery powered applications. These are manufactured to provide power and to control the motherboards' switch based on ignition status.
Solar Panels
Microfit can also be commonly found in a solar array. A solar array is connected to each other, and to inverters through connectors to produce a successful flow of electricity.
