What kind of data logger can shorten the whole vehicle development cycle?
01
In recent years, with the rapid development of the automotive industry and the continuous updating of new technologies, the traditional automotive test development cycle is long, which is no longer able to meet the demand for new technologies to be put on the market quickly or to adapt to the speed of market updating. By optimizing the testing method, multiple projects can be carried out at the same time, and the data will be grouped and sent to different departments for analysis after the test is completed. This not only shortens the vehicle testing cycle, but also accelerates product introduction to the market under the premise of ensuring full validation of the vehicle.

• Relying only on the test stand can no longer meet the test requirements, and test driving must be carried out in extremely harsh environments.
• Departments face high costs and long lead times invested in testing, and therefore need to accomplish testing as much as possible while keep test drives as few as possible.
• The variety of technologies used in automobiles is increasing, but the time to test the entire vehicle is constantly decreasing.

• The volume of data is large and complex, requiring a large amount of “parallel and real-time” data to be mastered, all of which need to be synchronized and recorded, and to ensure a high data consistency.
• The testing of emerging technologies such as driver assistance systems and autonomous driving brings new challenges, requiring data loggers to have high data transfer rates and abundant measurement channels for effective and fast data transfer and processing.

WINDHILL adopts high-performance data logger to provide a complete solution for automotive optimization test. Its main solutions and advantages are as follows:
• Variety of startup methods to ensure no message loss:
When starting a measurement, the data logger can be activated not only by key (KL15), but also by WakeOnRTC (Wake on RTC) or WakeOnBus (Wake on Bus). At the same time, the data logger supports NML (No Message Lost), which automatically starts when a bus message is received and saves all the bus message data completely in a memory group, making it easy to analyze the start-up process and wake-up behavior of the bus (ECU).
• Large storage space for multiple testing needs:
The data loggers have a large storage capacity, including the ETHOS2, which has up to 480GB of internal storage and 2T of removable storage (hot-swappable function supported). This allows the testing needs of several different sections to be integrated into a single system, thus providing the required measurement data for different departments in a single driving test and significantly reducing test costs.
• Data files can be grouped and encrypted to enhance processing efficiency and reliability:
The data logger supports the configuration of multiple storage groups, and different storage groups can store the data required by different departments. After the test is completed, the data can be sent directly to the corresponding department, greatly saving the time for subsequent data processing. In addition, measurement data can be stored locally in the logger or uploaded to the cloud, and the data can be encrypted, effectively enhancing the reliability of the data.
• The data logger has a wide range of interface types that allow for the simultaneous acquisition of multiple signals:
The data loggers include interfaces such as LIN, CAN FD, FlexRay, Analog and DIG IO. In addition, the data logger can also record GPS data, audio, video, sensors and other signals. All data can be synchronized to ensure data consistency and meet diversified testing needs.
• Supports remote function for online data monitoring:
The data logger supports WiFi/4G function and enable remote real-time monitoring and data upload through MQTT server and FTP server. TFM(Test Fleet Management Platform), the remote experiment management platform developed by WINDHILL, together with the logger, can realize remote real-time monitoring of the whole vehicle status, which is ideal for fleet management. In addition, the mobile version of IPEmotion ME can also be installed on tablet PCs and smart phones, which is convenient for users to monitor the operation data anytime and anywhere.

• The data logger can be synchronized to record data via standard protocols in combination with a variety of interfaces:
Standardized communication protocols (XCPonETH, PLP, TECMP, ASAM-CM P......) are used between the data logger system and the interface to ensure accurate time synchronization and enable data acquisition in parallel with commonly used automotive bus signals, etc. The standard ETH interface on the data logger system combines with these standardized protocols to support the use of multiple data acquisition modules and interfaces, as well as direct connection to PCs equipped with data acquisition software (supporting XCPonETH.) In addition, the system supports master-slave mode, which further extends the data acquisition capabilities.

• Low power consumption and extensive expandable interfaces:
The low power consumption of the device (e.g. the IPE853, with a typical power consumption of only 16W) does not put additional strain on the on-board power supply system, making it particularly suitable for the testing needs of hybrid and electric vehicles.
• Highly protective and can be used in extremely harsh environments:
The data logger can operate in a temperature range of from -40 to 85°C and relative humidity of 5% to 95%, and its IP54 protection rating ensures stable operation under harsh conditions.
• Variety of storage formats:
Depending on the version of the data logger, it supports a variety of storage formats, including ZIPRT, BLF, AVI, WAV, MDF4.0, MDF4.1, ASC, ATFX, PCAP, etc. to meet the data processing needs in different scenarios.
