Automated Test System – Automotive Speed Sensor
 Introduction :
Speed sensor acquires the speed data of an automobile and converts it into electrical signals to be read on the instrument cluster.
The Automated test system for speed sensor, consists of a fixture to load the sensor in place, a servo motor coupled to the sensor simulates the speed to be tested at. A virtual oscilloscope built into a PC, makes the measurement, compares with the standard, logs the result and marks the component under test for identification.
Highlights :
- A mechanical fixture hold the component in place with the help of pneumatics
- Industrial computer ensure rugged system for shop-floor environment.
- Virtual oscilloscope based on makes the measurement flexible and scalable.
- Logs the test results and reports in MS Excel.
- Scalability to test different type of sensors on the same system ensures ROI.
- Eliminates discrete test equipment, as this integrated test system performs all the required test and give out the result.
Automated In-process Test System for Automotive Instrument Clusters
Introduction :
Instrument Cluster is a dashboard component used in Automobile.
The test system developed is a customized ATE for in-process testing of various parameters in the instrument cluster, automatically. The instrument cluster consists of RPM meter, Fuel gauge, Temperature gauge, Oil Pressure gauge, Voltmeter, set of Telltale lamps (indication lamps) and either an Analogue or Digital Hour Meter.
Highlights :
- Design, Manufacture and Supply of in-process test system for electronic automotive instrument clusters.
- PC based test system
- Fully automated testing. Capable of testing six clusters at a time.
- A Variant information data base (VID) provides user to create new variant or modify or delete an existing variant.
- Generates serial numbers for passed components and print a bar code ID. For failed components the error codes are printed.
- Scalable and flexible system.
Data Acquisition and control for a solar power plant
Introduction :
A solar power plant typically consists of a string of solar cells called modules, which converts solar energy to electrical energy, then stored in batteries. The DC power from batteries is converted to AC using inverters or power conditioning units then distributed for utility.
To generate higher power arrays of solar modules are connected and huge banks of batteries are used.
Parameters like voltage, current generated by solar, intensity of solar, battery voltage, power, energy etc. need to be monitored and analyzed.
The data acquisition system developed by Micrologic acquires all these parameters on a real time basis, stores, analysis and presents on a remote computer.
Highlights :
- Design, manufacture, supply and install data acquisition system for solar power plant.
- 120 analog channels to measure voltage, current, power, solar intensity, temperature etc.
- Distributed I/O with diagnostics.
- Monitors all parameters on a PC, logs the values and interfaces to a Building management System.
- Network over a RS 485 bus communicates on Mobdus.
- Dynamic fault detection, Alarm and fault detection.
- Scalable to access the system from a remote location via the internet.
