Data Acquisition System suits vehicle performance testing.
Press Release Summary:
Interactive, in-vehicle, Web-Enabled Data Acquisition System with GPS supplies real-time data. Vehicle sensors are user-supplied sensor inputs to Data Acquisition Signal Conditioning Unit (DAQ) that monitor desired vehicle parameters. GPS antenna gathers satellite signal information which is processed, digitized, and stored for analysis. DAQ accepts 16 channels of analog inputs and provides gain, filtering, and signal buffering of analog voltages.
Original Press Release:
Automotive Testing in Real-Time from Anywhere with Web-Enabled Data Acquisition
1/06/04: On-road development tests evaluate the effects of weather and road conditions on ride, handling, steering, braking, noise, vibration and other systems. Development people in laboratory headquarters need to know exactly how their vehicle systems are functioning under every condition at all times. Electro Standards Laboratories had developed an interactive, in-vehicle, Web-Enabled Data Acquisition System (WEDAQ) with GPS to supply real-time data needed.
The vehicle sensors are user-supplied sensor inputs to the Data Acquisition Signal Conditioning Unit (DAQ) that monitor the desired vehicle parameters or performance. This system is interactive as system setup parameters are incorporated into the local (in-vehicle) side of the system, but can be modified by either the local-side user or the remote-side user.
The GPS magnetic-mount antenna, positioned on the vehicle roof, gathers satellite signal information for the global positioning DAQ subsystem. These signals are processed, digitized, and stored for analysis.
The DAQ accepts 16 channels of analog inputs. It provides gain, filtering, and signal buffering of the analog voltages and passes them to the laptop PC. An analog output is provided for general usage.
The laptop PC, serving as the host platform for the system, provides data digitization and local data storage of all sensed channels. It also acts as the conduit for remote Internet access to streaming data and archived test data. The Internet access is accomplished with a wireless modem integrated into the laptop PC. The DC/AC inverter module uses the 13 VDC vehicle voltage to generate a standard AC voltage to power the laptop PC.
The compact dashboard-mounted Quick View Driver LCD Display is cabled to the DAQ. The display can be set to show the current value of any sensed signal during a test.
