BUS DESTINATION BOARD CONTROLLER DESIGN PROJECT

CUSTOMER REQUIREMENTS
A Bus Body Manufacturing Client came to us with a challenging requirement. The Goal was to design a robust and reliable control System for the multiple destination boards within a bus. The entire system should be centrally controlled. The system should be able to take at least 1000 routes as input. A Route Design and Upload Software was to be developed for the route design and display. The Display should be able to support any language, Indian or Foreign. The Central Control Unit is to be equipped with multiple interfaces like USB, LCD etc. to ensure ease-of-use for the operator.
KEY CHALLENGES
The physical environment within an automotive is very harsh, especially during motion. The temperature and noise within the environment requires precise design. The communication system design should be rugged, reliable and noise resistant. The multiple language support would require implementation of multiple libraries and could take many months to complete. The system was to be made user-friendly and simple to use as it was to be majorly operated by Bus Drivers and Conductors.
VISO SOLUTION
VISO proposed a master-slave solution using RS485 Modbus as the communication technology. The single master, multiple slaves architecture was implemented by following the RS485 standard perfectly. For the Route Design Software, image processing algorithms were used. This ensured that the system could support any language all over the world. VISO even provided with a simulation feature within the software that would show how the routes would look while scrolling across the board. Interfaces like USB , LCD etc made the usage of the equipment very user-friendly. The response time of the system increased significantly as compared to previous systems.
