At first glance, we are a little late in positioning a new 2.4GHz RC system, but when looking at it from a closer point of view, this fact gives us a unique advantage:
When developing the new platform, we don't have to compromise on compatibility with other systems and can therefore set new standards in the 2.4GHz RC range. The safety and functional stability of the CORE has the highest priority.
Radio transmission and power supply
Weatronic's tried and tested frequency hopping method is used for the radio link. This method is known for highest reliability and range. The CORE has a redundant design of the radio link, which is monitored by the receiver. A defect, e.g. in a transmitter unit, is immediately signalled by the receiver via telemetry. The power supply of the CORE PowerBox is typically redundant. This means that two separate Li-Ion battery units with 3400mAh/7.2V each and the entire voltage regulation are installed twice, a feature that only the CORE currently has. This enables us to achieve a runtime of approx. 15 hours at full screen brightness and maximum system utilization.
As we believe telemetry will become increasingly important in the next few years and demand will increase significantly, we have dealt with this topic in great detail. Currently there are some manufacturers of telemetry sensors which are already being used by many customers. But often the telemetry transmission contained in the transmitter system cannot transmit so many values or the transmission becomes very slow with increasing number of connected sensors, which is exactly where the strength of the core system lies:
The telemetry handling and transmission has been completely redesigned, so up to 250 sensors with 32 data values each can be connected to the P²-BUS and transmit up to 800x16 bit values per second. This opens up completely new possibilities for the future, such as real-time servo monitoring in the model. Our P²-BUS telemetry interface is open to third-party suppliers, so the customer does not necessarily have to switch to new sensors in his model. In this case a software update of the sensors would be sufficient. The configuration and parameterization of the entire telemetry system is done conveniently via the transmitter via radio link.
Linux with smartphone character
The core transmitter has a modern, powerful Linux PC built in. The operation is carried out exclusively via the touch screen. The methodology and haptics are the same as for a smartphone. In combination with an intuitive user interface, which allows all related settings to be reached quickly and easily, the programming of a model is completed with just a few inputs. The user interface has been fully programmed with the Qt toolkit. Today this development environment is the standard in the embedded GUI area and is used by many well-known manufacturers.
The display used is manufactured according to the specifications of PowerBox Systems and is very easy to read even in full sunlight. The capacitive touchpad can be operated simply by lightly tapping the surface. The smartkeys at the bottom of the screen allow accelerated access to important functions such as the servo monitor and screen lock.
The internal data communication is realized via CAN-BUS. This bus system is designed for our application and has been used successfully in the automotive and aviation sectors for many decades. A proof for the fast processing of our system can be found in the servo monitor: The obedience of the display to the control movement of the encoders is absolutely real time! The already used OpenGL support of the Linux computer leaves nothing to be desired in terms of graphics for the future.
The transmitter is always completely equipped with regard to the encoders except for the knob switches. If required, these can be retrofitted by the customer himself or by our service department. The hardware for the connection in the transmitter is already prepared for this. That means that we have not only liked the two from the full range.
