Machine Control and IOT Used in it.

What is GPS and GNSS ?

                          GPS  – Global Positioning System , is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force.

                            GNSS - Global Navigation Satellite System ,  is a system that uses satellites to provide autonomous geo-spatial positioning. It allows small electronic receivers to determine their location to high precision using time signals transmitted along a line of sight by radio from satellites.

                                            Add in – GLONASS(Russia) – Galileo(EU) – BeiDou(China) – QZSS (Japan) – …and you have the modern GNSS

           How GNSS Work

                            ▪ Trilateration – it is all about timing…not angle

                            ▪ To the whiteboard 

                            – Code phase 

                            – Carrier phase 

                            – Corrected solutions 

                            ▪ Base stations 

                            ▪ SBAS   

                            ▪ RTK 

                            ▪ VRS 

                            ▪ IBSS

Machine Grade Control

                        ▪ Applying a range of technologies to heavy earthmoving equipment to either indicate or automate the control of the work tool relative to a predetermined surface or design

 

                        ▪ System tells you where to put the blade/bucket or we do it for you…relative to the design you are trying to build

 

                        ▪ Think of it as CNC machining for the earth’s surface

What are the benefits?

                             ▪ Following numbers from a production study in 2006 – and things have only got better since then! 

                             ▪ Road construction study – Two side by side identical roads – One built with conventional methods the other with machine control and guidance – Measuring the following:

 

                             ▪ Overall productivity     

                             ▪ Machine utilization     

                             ▪ Fuel consumption     

                             ▪ Number of people on site 

                             ▪ Finished design quality

Production Study

                 ● 100% Increase in Productivity

                         ● 3.0 days vs. 1.5 days 

                 ● Increased Machine Utilization 

                         ● Less waiting time 

                         ● Longer passes 

                  ● Savings in Operating Cost 

                         ● 43% less Fuel consumption 

                         ● Less wear on machines 

Machine Control Components

       At this part IOT Devices plays a major role like

                   ▪ Human-Machine Interface – Display – Lightbars – Buzzer – Switches 

                   ▪ System-Machine Interface – Valve Module (unless the machine is electro-hydraulic already) 

                   ▪ Power Management – 12/24v relay

Example

Communication Protocols 

                                           ▪ CANbus – Controller Area Network; message based protocol designed originally for multiplex electrical wiring within automobiles 

                                           ▪ Ethernet – 4 wire – 2 wire 

                                           ▪ Serial 

                                           ▪ WiFi

Communication Types

 CAN                                                                         ETHERNET

          - Bus network                                                                         - Tree network

          - Terminated                                                                            - Point to point

          - Bus length                                                                             - Max length

          - Stub length
