Engine test

In aerospace and military industry, R&D engineers face unprecedented challenges. This includes reducing the size of the internal combustion engine, as well as new product requirements constantly proposed by customers. In the face of these challenges, detailed and accurate testing is essential. Therefore, DVC has designed a special test system for aviation test and defense weapon test. Our data acquisition equipment can simultaneously acquire/record hundreds of channels. In addition, we also provide signal conditioning amplifiers with multiple sampling rates ranging from 100Hz to 10MHz. Most importantly, you can view the test results in real time in the control room. DVC products are based on modular design, so it is very easy to use and test for aerospace and national defense with complex test signals. At the same time, our test equipment also has the characteristics of high isolation, high bandwidth, distributed flexible testing and continuous data storage.

Wind tunnel test

The whole aircraft and its components need to be connected to a large number of different sensors for aerodynamic testing. Due to the existence of a large number of sensors, as well as the high dynamic range and high sampling rate of signals, it is extremely important to synchronously collect and store all signals in wind tunnel testing. The modular design and synchronization technology of DVC can ensure the synchronous testing of 16 to 2000 channels. At the same time, the rugged chassis and reliable PXI bus ensure that the equipment can be used reliably in harsh environments. In addition, the synchronous acquisition of high-speed cameras and analog signals is very easy to achieve with the use of DVC products.

Highlights: it can synchronously measure electric vehicles and internal combustion engine vehicles, synchronously test high voltage/current and CAN/FlexRay bus signals, online electric energy/power/efficiency calculation, bandwidth up to 2MHz, and sampling rate up to 10MHz.

Advanced Driving Assistance System (ADAS)

Every modern vehicle is equipped with an advanced driving assistance system (ADAS). One of the challenges of ADAS testing is to accurately measure the relative position and speed between vehicles when testing the longitudinal control system. In addition, it is very difficult to locate the position of the vehicle during the test of the lateral control system. Therefore, DEWETRON has developed corresponding test tools. Based on our modular design, you can adjust the signal conditioning board card according to different test tasks, so you can use a set of equipment to complete all ADAS tests. In addition, a test solution can perfectly and synchronously collect all test signals from multiple vehicles or other moving objects.

Adaptive Cruise (ACC)

It can test the relative position and speed between moving targets (vehicles), and ensure the synchronization of all test signals.
Test signal: relative distance between vehicles; Absolute speed and relative speed; Longitudinal acceleration; Longitudinal deceleration; Sound test; Visual/tactile warning signal; Lateral offset

Automatic Emergency Braking (AEB)

According to the European NCAP standard, automatic emergency braking needs to test the relative data between the driving vehicle and the simulated target vehicle (rabbit car). Due to the potential collision risk, it is impossible to install test equipment other than IMU on the target vehicle. With the powerful calculation and processing functions of the OVYGEN test software, you can obtain accurate positioning information. In addition, during the AEB test, the driving robot is often used to obtain accurate vehicle control. DVC can obtain various sensor parameters and gyro/GPS information, and can also read the data of the driving robot.
A variety of signal acquisition makes the test data more accurate and comparative.

Front Vehicle Collision Warning (FCW)

The main objective of the FCW test is the exact point at which the vehicle alerts the driver before a collision hazard occurs. Therefore, the trigger time of sound/touch signal can be determined by collecting the CAN bus signal. In addition, DEWETRON's FCW vehicle test solution also meets the requirements and specifications of NHTSA, which is the requirement for obtaining FCW approval in the United States.
Test signal: position/track of two vehicles; Speed of two vehicles; Yaw rate of two vehicles; Vehicle deceleration; Audible/optical warning signal.

Lane Keep/Departure

For vehicle lateral control systems, such as lane departure warning or lane keeping assistant (LDW/LKA) testing, the measurement system needs to calculate the relative position, angle and speed between the vehicle and fixed objects (such as lanes, curbs or traffic signs). At the same time, in this test, the synchronous acquisition of video data is particularly important.
Test signal: distance from the centerline, sideline or road edge; Steering angle, current vehicle speed; Lateral acceleration; Yaw angle; Audible/visual and/or tactile warning time; Driver's perspective (video)

Vehicle dynamics test

At present, many manipulations have been standardized in the automobile testing industry to evaluate the driving and handling ability of vehicles. DEWETRON's vehicle test solution has established a perfect position in vehicle dynamics measurement due to its ease of use, flexibility and compatibility with sensors. In addition, OXYGEN software can also display the track, map information and relative position of the vehicle in the whole movement process, and combine graphics and video to make your data results more comprehensive.
Advantages: Seamless communication with IMU, which can accurately measure GPS position information, acceleration and angle; Connectable Kistler ® Wheel force sensor (RoaDyn ®）； Obtain vehicle bus data synchronously via CAN or CAN-FD.

Durability test

Durability or road load data testing usually requires a large number of test channels. Therefore, this kind of test needs scalable hardware systems. In addition, powerful software functions are also necessary for monitoring and processing signals of hundreds of channels at the same time. Therefore, DEWETRON's measurement software can provide a perfect vehicle test solution. Since the actual test driving data is usually played back on the test bench to simulate the material fatigue in the vehicle life cycle, the analog signal output function after sensor acquisition is also essential.
Advantages: Seamless communication with IMU, which can accurately measure GPS position information, acceleration and angle; Connectable Kistler ® Wheel force sensor (RoaDyn ®）； Obtain vehicle bus data synchronously via CAN or CAN-FD; The sensor test data can be input to the test bench in the form of analog signals; Support TEDS and sensor database; Offline setting; Real time monitoring (overload indicator, sensor balance, amplifier zero and strain calibration)

Industrial measurement

High speed data recorder

In order to meet the requirements of high-speed acquisition and storage, DVC has developed a test board with a sampling rate from 200KS/s to 10MS/s to ensure high-speed data acquisition and storage. For high-speed storage, it is divided into high-speed continuous data storage and instantaneous data storage. Devtrong can store the test data to the SSD at the rate of 1GB/S, and the capacity of the SSD is several TB. Similarly, for instantaneous storage, DVC equipment can also collect data at 10M sampling frequency and store the data to solid state disk at the rate of 4GB/channel/s.

Distributed measurement system

In industrial testing, it is often necessary to carry out synchronous testing and store data in different locations. For example, in power testing, we need to synchronously test the power parameters at both ends of the transmission grid, or test multiple vehicles synchronously, or test the synchronization between different carriages in the train. For these complex test applications, based on our modular design and perfect equipment synchronization function, Devtrong can provide you with mature solutions. In this application, we recommend the use of portable TRIONet equipment. This equipment is not only small in size, convenient for distributed layout, but also very simple for long-distance synchronous testing to ensure the data synchronization of distributed measurement.

Order analysis

In the start and stop phase of rotating machinery, it is easy to have faults or hidden defects. Therefore, the order analysis function of DVC can easily analyze the operation of equipment under different speed conditions by tracking the speed and frequency. More importantly, our order analysis equipment can take into account the functions of wave recorder, oscilloscope, power analyzer, modal test, etc.

Torsional vibration analysis

Rotating machinery will be accompanied by noise and vibration when running, and these rotational speed vibration will often lead to fatigue damage of parts. Therefore, in industrial measurement, the measurement of torsional vibration is very important. High angle resolution or high time domain sampling rate is required to collect angle signal in torsional vibration test. DVC can provide you with appropriate measuring equipment:

·Simultaneous analysis of multiple groups of signals

·Support various types of encoders and angle sensors, and the angle trigger value is 0~40V programmable and adjustable

·Digital filtering of speed signal to reduce noise interference
