Case Study BM206k Automotive On-board Computer

  1. 1. In-car monitoring device for agricultural machinery Completed project - April 2006 Customer The Aladin company, supplier of components and comprehensive solutions for agricultural machinery. Objective To develop, conduct experiments and prepare design documentation for mass production of the in-car harvester- thresher monitor, which analyzes technological operating modes and controls harvesting parameters. The challenge lay in creating a competing product in price and under strict time constraints. Solution The development fit extremely tight timeframes, with the first prototype created in a month and a half after development had started. Concept “We were under very strict time constraints - we had to create sample prototypes to A technical level map with participate in the tender for supply of large comparison features of competitive consignment. We already started to get products was compiled. On its basis, reconciled to giving away a part of the functional and technical market to the competitors. At the end of characteristics for a new product January, we sent a request to the Promwad were determined, plus some unique company asking to estimate the timeframes features were suggested: required to develop our product. The reply • An event log to control the was rather unexpected - 2.5 months for the operating modes of the entire scope of work. We grabbed this machinery; chance, and as soon as in 1.5 months we received a first sample prototype that was • Custom sensor sensitive highly appraised by the manufacturers of parameters for various crops; harvesting machinery…” • CAN interface.

  2. 2. In-car monitoring device for agricultural machinery By agreement with customer, specification requirements for hardware, software, and design were elaborated and validated. Hardware design Promwad implemented an electric schematic diagram on the basis of the AT90CAN128 microcontroller, with a possibility to use MCU ATmega128 in a low- cost model. An interface with a high-resolution LCD was developed. Power outputs and power circuit were protected from polarity reversal and short circuit, and integrity control was ensured for connection lines of external sensors. The device has an inherent capability of on-board programming and firmware update that does not require opening the enclosure. Large-scale nonvolatile memory storage allowed saving events with real time reference. Design and ergonomics An appealing and easy for the eye front panel represents a film membranous pad displaying intuitive icons. The graphical interface comprises around 30 screens with 240x128 resolution, thus making user interface convenient and adaptive. Framework The enclosure is based on the OEM solution by OKW. The enclosure design compiles with the All-Union Standard on in-car electronic devices for agricultural machinery in dust- and waterproofness (IP65), shock and vibration resistance. The modular design simplified the assembly and increased repairability of the device. The side panel of the screen has separate slots for the CAN interface, a technological slot and a programming slot. The device can be mounted in any suitable place of the driver booth with an external bracket. e-mail: info@promwad.com; www.promwad.com; phone: +375(17)312-1246 © 2009 Promwad Innovation Company 2
  3. 3. In-car monitoring device for agricultural machinery Software A sketch map of the graphical user interface has been made that became the basis of writing the GUI programming code. The algorithms of collecting statistical data about the machinery maintenance enable the warranty and post-warranty services quickly detect the source of trouble. A package of firmware and application software combines the graphical interface with technological machine control functions. Quality assurance At the beginning of design process, specification requirements were checked for compliance with the All-Union Standards, later at the prototype preparation stage the device was tested for compliance with specification requirements. The user interface was field tested and received feedback from combine operators, which allowed making changes to increase the convenience of use. e-mail: info@promwad.com; www.promwad.com; phone: +375(17)312-1246 © 2009 Promwad Innovation Company 3
  4. 4.
