Mobile automation
Under Mobile Automation , and mobile electronics , refers to the in mobile working machines installed electronic systems for machine control with the exception of motor control . Not to be confused with the term portable electronic device or mobile phone .
Mobile machines contain more and more electronics . These are, for example, vehicles such as construction machines , agricultural vehicles, rail vehicles , municipal vehicles or even fire engines . In addition to the electronics for the vehicle itself, for example for engine management, there are a number of very special functions. Raising and lowering a unit on a tractor is one such functionality.
Mobile electronics is usually divided into four sub-areas that provide all the necessary components:
- Display elements & controls
- Sensors
- Actuators
- Control units with software
The components required for this are not unlike those of the machine control ( programmable logic controller , PLC) from industrial manufacturing technology .
Robust devices
In order to guarantee the reliability and availability of the mobile work machines, the mobile electronics are developed and produced according to the standards of the automotive electronics and thus differs significantly from electronics for industrial automation. The mechanical structure of the components is determined in particular by the use and environmental conditions, which are much harsher than in the motor vehicle.
Robust metal housings are required, as are electronic components for a temperature range of −40 to +85 degrees Celsius . Most devices must be designed for higher protection classes, for example IP 67, as they are very often built directly onto the vehicle and are not protected by a control cabinet .
communication
A complete, electronically networked machine control system can be built from the individual components through standardized interfaces (e.g. sensors with 0 to 5 volts, actuators with 0 to 2 A).
As in the passenger car sector, the CAN bus (via CAN SAE J1939 or CANopen ) for networking the components has established itself in mobile automation for communication . A wide variety of protocols are run on it, some of which were specially developed for mobile automation . Current devices have increasingly, an Ethernet - interface that is been used in particular for programming, although Ethernet TCP / IP and the potential for real-time communication would offer. Ethernet could play an important role in the future where several CAN lines are currently run in parallel for reasons of performance.
programming
Machine control software is mainly developed according to the IEC 6 11 31 standard and in the high-level language C , C ++ or a "PLC language" from the world of industrial automation technology.
A different tool such as that used for software development is usually used for diagnostic access.
providers
Medium-sized companies in particular are active in the still rapidly developing market, such as: (alphabetical order)
