Veronte CEX – Drones Information
Veronte CEX is a powerful peripheral device that makes it easier to reduce cables in autonomous vehicles if the number of devices in the system is to be increased. With its simple integration, Veronte CEX becomes a quick solution to increase connectivity capacity and optimize wiring, especially in large systems. It enables the relocation and grouping of sensors, actuators, payloads, engine controls … and improves I / O connectivity in the Veronte autopilot.
This is especially true for large vehicles, where cable optimization plays a crucial role in enabling significant weight reduction. This upgrade is achieved because, depending on the system scheme, we only use 2 or 3 cables and therefore can also reduce the cable length. Another advantage of using Veronte CEX is the robustness of the CAN bus connection, as it is very resistant to electromagnetic interference and allows the installation of long cables without signal loss. In addition, it contains redundant CAN bus isolation, which means that it also fails in the event of a CAN bus line break.
Improved I / O
Using Veronte CEX significantly increases the data capacity for input and output in Veronte autopilots. The advanced design enables the control of several peripheral devices and components (PWM, UART, digital output, I2C, analog inputs …) via the CAN bus. It can be used both to expand I / O capability in the Veronte autopilot and to control peripheral devices with a robust and stable communication protocol. If necessary, we can install multiple CEX cards on the same network to increase the number of I / O ports, or simply due to the requirements of the system architecture.
Redundant CAN bus
Safety is an essential and critical factor in the autonomous vehicle industry, especially if the focus is on a UAV certification process. Redundancy is a basic requirement for any system that has to meet demanding security levels. It ensures the correct operation of the components in all situations and remains failable even if the CAN bus line fails. The redundant CAN bus ports are galvanically isolated in order to avoid propagation without the desired electrical currents in the system. If one of the lines is affected by an electrical problem in the system, the other CAN bus line remains in operation.
In aeronautics, an area where weight is so important in the design of aircraft, the wiring problem is one of the most common problems that the vehicle design phase faces. With the use of Veronte CEX not only this problem is greatly reduced, but there are also a number of possibilities for different sensors and payloads:
- An extended control of actuators and peripheral devices is possible because the connection of control, feedback, sensors … can be combined in a single board.
- Thanks to the robustness of the CAN bus, devices can be installed far away from the autopilot without signal degradation.
- By adding more I / O interfaces, more complex payload control can be achieved, which improves connectivity.
