  1. By Robert Emin Labview Postgresql Connectivity

  2. Sensor ---> 16 Gauge Wire Data Acquisition Device ---> USB Windows Computer Labview API TCP/IP ---> Ethernet Linux Server Postgresql Data Flow

  3. Used to measure the presence of a magnetic field. Hall Effect sensors are used for proximity switching, positioning, speed detection, and current sensing applications. They are used for electronic compasses, clamp-on sensor, analog multiplication, current sensing, position and motion sensing, automotive ignition and fuel injection, wheel rotation sensing, industrial applications, spacecraft propulsion and as many as there is creativity. 4.5 to 6 V input Ground 2.5 V output Allegro 1301 Hall Effect Sensor

  4. Voltage Measurement -10V to +10V Analog Input Analog Output Digital Input Digital Output Counter USB National Instruments 6211

  5. Most stable version of Windows operating system. Most supported by National Instruments. Ideal for running real time applications under the Microsoft line of products. Microsoft Windows 7

  6. Most popular product in engineering for data acquisition and control development. It is a visual development environment Versions for Mac, Linux and Windows. Its programs and functions are known as VI's. Has been around since 1983 and dominates the industry. On Windows, it is an open architecture allowing to directly interface with dll's, activex, .net and other Windows products. National Instruments Labview

  7. A collection of Labview VI's built from dll's belonging to the Postgresql library libpq. This allows Labview to directly communicate with Postgresql. Has speed and reliability advantages over other products. Postgresql2Labview

  8. This system uses Debian Linux. Free. Stable. Secure. Can view the source code. Tools for making true real time systems. Linux

  9. Open source. Free. True RDMS and object orientated. Robust. Secure. Can see the source code. Postgresql

  10. CREATE TABLE "public"."work_voltage" ( "voltage" DOUBLE PRECISION NOT NULL, "date" DATE DEFAULT 'now'::text::date, "time" TIME WITHOUT TIME ZONE DEFAULT 'now'::text::time without time zone, "identifier" BIGSERIAL, CONSTRAINT "work_voltage_pkey" PRIMARY KEY("identifier") ); Courtesy of Lloyd Albin Table Structure

  11. Labview Call Library Function

  12. Interfacing with the dll

  13. Any Questions???
