OBDII ODOMETER  OBDII车上诊断系统里程表

The OBDII Odometer is a smart interface cable that communicates with a vehicle's on-board computer to determine the current vehicle speed. It outputs real time vehicle speed over an RS232 serial data interface. When connected to one of Advanced Navigation's Spatial series of GPS/INS products it allows for outstanding navigation accuracy when GPS is not available.

It outputs real time vehicle speed over an RS232 serial data interface. When connected to one of Advanced Navigation's Spatial series of GPS/INS products it allows for outstanding navigation accuracy when GPS is not available, down to 0.05% of distance travelled.

OBDII车上诊断系统里程表是一种智能接口电缆,与车辆的车载计算机通信以确定当前车辆速度。 它通过RS232串行数据接口输出实时车速。 当连接到Advanced Navigation的Spatial系列GPS / INS产品,它允许杰出的导航精度,当GPS不可用时,误差低至0.05%的行驶距离。

FEATURES特点

SUPPORTS ALMOST ALL VEHICLES 支持几乎所有车型

With built in support for eleven different OBDII communication protocols, the OBDII Odometer supports almost all modern vehicles on the market. It is completely plug and play with no setup required and can be switched between vehicles in seconds.

ABS SPEED AND REVERSE DETECTION 防抱紧制动速度和变速箱反转侦测

On GM, Ford and some European vehicles, the OBDII Odometer is able to retrieve vehicle speed from the ABS (Anti-lock Braking System) system which provides a very high resolution speed. On all other vehicles the OBDII Odometer will provide speed from the transmission which is still a very accurate reference. The OBDII Odometer is also able to determine when the gearbox is in reverse on a range of vehicles.

MINIATURE DURABLE DESIGN 小巧耐用设计

The OBDII Odometer has a miniature in-line design that is easy to fit into any vehicle. It features a strong ABS plastic shell and tough strain relieved cabling.

RELIABILITY可靠

The OBDII Odometer is protected from surges, reverse polarity, brown outs and overvoltage to continue operating through harsh electrical conditions. It's communications interface is optically isolated to prevent ground loops and protect sensitive equipment connected to it. It is built on top of a safety oriented real time operating system and all software is designed and tested to safety standards with fault tolerance in mind.

APPLICATIONS应用

URBAN NAVIGATION城市导航

In urban environments where multipath is a big problem for GPS/INS units, the OBDII Odometer can help to increase accuracy and reduce position drift.

SECURITY安保

In security applications where GPS systems may be jammed, the OBDII Odometer can assist a GPS/INS to continue providing accurate positioning through jamming.

SURVEYING测绘

In surveying applications that require continuously accurate positioning even when passing under heavy tree coverage and through tunnels, a GPS/INS combined with the OBDII Odometer is able to provide the results required.

MINING矿业

For mining applications that need to monitor vehicle speeds around the site for safety, the OBDII Odometer can be used standalone to easily retrieve the required data without any intrusive installation.
