What is data logging?
Data logging is the ability to monitor different functions of the engine while actually driving a car on the road or on a dynamometer. We sample approximately 30 different inputs simultaneously at over 10 Hz each. That means each channel is updating itself 10 times a second! We monitor requested load, actual load, requested boost, actual boost, timing, intake air temp, knock on each individual cylinder, fuel, rpm, as well as proprietary tuning functions.
Data logging or acquisition is, in its simplest terms, the procurement of information in order to learn more about a process or system. It forms the basis of an understanding of a diverse range of systems. The logging and saving of information provides for increased knowledge and sometimes improved management of how and why different processes work. Many loggers archive information such as temperature using sensors and then convert the information into electrical signals. The data is archived and once retrieved can be filtered and properly understood. To begin the process we need a data logger. This could be a stand-alone logger or personal computer (PC) based device. The data logger is an instrument that connects to other devices for the sole purpose of collecting information. The stand-alone logger has many advantages over the PC based logger. Many have their own back up power source in case of power failures so that vital information will not be lost if there was a power failure. As
===================== Data logging is making measurements and recording them against time. You could, in some cases, do this by hand. But for increased speed and accuracy, in hostile environments, with unattended monitoring or logging over long periods of time – you need electronic data logging. * How to Electronically Log Data ============================== One method is with a stand-alone data logger, which you later plug into a computer to access the data. Alternatively you can use the PC itself as a data logger. The list of measurements that can be computerised is almost endless: temperature, pressure, strain, position, depth, rainfall, salinity, humidity, flow, pH, vibration, windspeed and so on. Using the PC as a data logger means a more flexible system with a real-time view of data trends via charts, tables or other displays. It also allows automatic control should set limits be exceeded. For example, if a temperature reached a certain level then a heater could be turned off. Th
As science and technology have developed, so the need for data collection and analysis has grown. This is fulfilled, at least in part, by dedicated, microprocessor-driven data loggers. The modern data logger is typically a hand-held battery-operated device with a large memory, powered by the latest microprocessor technology and capable of acquiring, processing, storing and analysing electrical signals at high speed from a wide range of sensors – at regular intervals or in response to an event such as a threshold being crossed or a switch being activated. The sensors may communicate with the logger through a cable or wireless link and may sense temperature, humidity, pressure, flow, wind speed, current, voltage, resistance and a host of other physical parameters that are important in monitoring and controlling processes or conducting research. Data stored by stand-alone data loggers is typically downloaded into a computer for more detailed analysis and reporting, though some data logger
