1. Product Introduction
1.1 Product Overview
In the CAN bus troubleshooting, the biggest difficulty is occasional faults. This makes
engineers or even CAN experts unable to accurately identify the fault cause. For example,
the pitch system of the wind turbine had a CAN data transmission interruption in 72 hours;
the dashboard of a new energy vehicle appeared "blank" once during a 10,000 km drive,
but this could not reoccur; the high-speed train experienced an emergency deceleration
due to abnormal CAN communication during a 2,000 km journey. These occasional
CANFD communication exceptions have frightened engineers like time bombs. If one
CAN bus data recorder is installed on an occasion prone to faults, it is equivalent to a
"black box" to record CAN data, which helps analyze the fault cause.
Guangzhou ZLG Electronics Co., Ltd., as a leading manufacturer of the domestic
CAN bus, has developed CANDTU series products for troubleshooting CAN buses, which
can record CAN messages offline and perform GPRS and 4G transmission. It can easily
complete the message recording and on-site monitoring of applications such as vehicles,
ships, elevators, wind turbines, and construction machinery.
CANDTU-200UWGR series products are storage-type 2-channel CAN bus data
recorders. The products can run independently from the PC and store CAN message data
for a long time, which facilitates analysis and troubleshooting. The recorder can transfer
the recorded data to a PC via an SD memory card. After format conversion of the raw data,
users can analyze and evaluate the recorded data offline by using CANoe and
CANScope.
CANDTU-200UWGR also supports 4G communication, which can upload the
data on the CAN bus to the specified server.
Support GPS/Beidou positioning and
record the device localization real time.
The CANDTU-200UWGR is also a CAN-Bus bus communication device that
complies with USB2.0 high-speed specification protocol and integrates two CAN
interfaces. The PC can be connected to the CAN-Bus network through the USB bus of the
device to realize the data mutual transmission between the PC and the CAN-Bus network.
