Diesel-engined Particulate Filtration Tests In Cars With GPS DEVICE Logging

The dilemma is that practically each new filter requires a new design and style because of the assortment of exhaust methods and their different temperature and stress running stages. Throughout take a look at drive filter temperature, strain, motor speed, idle moments, automobile placement and velocity want to be measured precisely and reliably to verify that the filter meets the required expectations. In get to record the take a look at data consumer made a decision to use a knowledge logger in mixture with a GPS sensor to document measurement info from the filter in mixture of car placement data.

For this logging software the consumer is employing TopMessage data logger with 2 modules. The total system is put in in a climate evidence enclosure and the sensors are interfaced to the enclosure by way of particular connectors.

For the duration of the take a look at travel all test data is recorded to the inner memory of the TopMessage info logger. The pace of the engine (rpm) is recorded by way of a separate pace meter (DAB 500 from AVL) which is offering TTL pulse output. The pulses are then recorded by the counter and inputs of the DIOT module. The dwell knowledge is visualised by means of a mimic interface of the ProfiSignal Standard software program.

In get to report the motor vehicle velocity and direction a particular NEMA driver for a GPS sensor was designed. This driver is interface to the TopMessage via serial RS232 port. The GPS data like pace, route, altitude a different COM channel is designed and all the info is saved right in the 1 GB TopMessage data logger memory.

After paccar px8 dpf delete is concluded, all the information is analysed with the ProfiSignal software program. It is also feasible to convert the GPS info into a KLM file which can be loaded by Google Earth to plot various measurement channels like car speed, filter temperature or stress of position or motor speed.

Summary of Rewards:

The client is using now five Data Acquisition methods to run the diesel particulate filter testing. The main benefits for them are:

The 1 GB inside memory offers storage capability for numerous thousand examination drive kilometres.
Simple to configure ProfiSignal application to display stay reading for the duration of the examination drive.
The interface of the GPS sensor also gave beneficial extra info about car velocity in combination with engine RPM and particle emission.
The common analog inputs made it very simple to connect the temperature and force sensors.
The tiny and compact measurement of the knowledge logger of (200x73x118) mm produced it extremely sensible for the set up in a small enclosure.
In inner calculation and logic channels exactly where utilised to set off data logging when check problems are arrived at.
