Pave Green – Road Surface Recycling
PLC & HMI Program upgrade and optimization for Road surface recycling system, using Allen Bradley PLCs and HMI
ControlSoft Canada, rebuild and upgraded the original control system for fully automated operation, introduced
- Closed loop control using PID ladder logic for recycled asphalt oil mixing ratio to optimize surface hardening
- Closed loop control with PID for propane gas supply for heating old asphalt as the vehicle moves
- Closed loop control with PID for hot air supply for blower to pre heat road surface
- Speed monitoring using pulse encoder feedback to PLC analog input, to display all 4-vehicle speed, and using speed to control recycled asphalt + oil mixing ration
- Program HMI display screens to show process parameters to vehicle drivers during road recycling process
- Design alarms and warnings logic to show on operator HMI screens.
- Supporting Pave Green operation team for PLC & HMI software support during critical road surface recycling work both remote and on site.
- Supporting Hot in Place Road surface recycling technology development with Pave Green
