Detta examensarbete har gått ut på att undersöka möjligheten till implementerande av ett trådlöst mätsystem för en turboladdare samt sedan ta fram en basinstallation för det valda systemet. Genom att tillämpa användningen av ett trådlöst mätsystem till Scanias turboaggregat så kan mätvärdena som erhålls användas till fortsatta designförbättringar och verka som en kontroll av Scanias turboleverantörer. Arbetet har behandlat studier i olika trådlösa mätsystem och sedan utse det som passar Scanias turboaggregat bäst, detta blev då telemetrisystemet. Arbetet fortsatte med etablering av kontakt med leverantörer och senare matcha Scanias krav och begränsningar med leverantörens föreslagna system. Arbetet har också hanterat framtagandet utav CADmodeller, ritningar för en monteringslösning till telemetrisystemet. Detta betydde att konstruera inom turboaggregatets begränsningar och driftområden så att monteringslösningen kan hantera de hårda förhållanden systemet kommer utsättas för vid drift. Arbetet resulterade med en framtagen offert och en systembeställning av ett 2 kanalsystem, även framtogs två stycken olika monteringslösningar som kan användas för fästa av telemetrisystemet i turboaggregatet., The aim of this thesis has been to investigate the feasibility of a wireless measurement system for a HD turbocharger, and then implementing a base installation for the selected system. By applying the usage of a wireless measurement system to one of Scania’s turbochargers, the measurement values that obtained can be used for design improvements and as a verifier of Scania’s turbo suppliers. The thesis has covered studies in different wireless measurement system and later choosing one that fits Scania’s turbochargers best, this became the telemetry system. The thesis has also covered the development of CAD-models and drawings for a mounting solution to the telemetry system. This meant designing within the turbochargers design limits and operating areas so that the mounting solution could deal with the harsh condition the system will be exposed to. The thesis resulted in ordering the 2 channel telemetry system and a development of two different mounting solution that can be used to fasten the telemetry system within the turbocharger.

The detailed design of electrical systems of the NDAS (Neural Data Acquisition System) was carried out. The NDAS is composed of the DIU (Data Interface Unit), DR (Data Recorder), TDPU (Telemetry Data Processing Unit), Rx (Receiver), Tx (Transmitter), and induction coils. The specifications of these equipments were decided. The detailed designs on the drawers of the DIU and DR, composing the mechanical system of the NDAS, and those on the VFEU (Vestibular Function Experiment Unit) and the supporting structures of the DIU and DR, composing the rack outfits, were carried out. Furthermore, a test to acquire the basic data on the onboard model for breeding of Opsanus tau was carried out using the experimental model of the VFEU fish package bath. The other tests conducted included a test to verify the water quality maintenance, a test to confirm excitation methods, a test to confirm emergency influence, a test to confirm the wash and storage method of the equipment, and a test to confirm onboard conditions of syringes. In addition, the single body functional test and the aeroplane experiment of the NDAS experimental model were performed., NDAS(神経活動電位計測装置)の電装系に関する詳細設計を実施した。NDASはDIU(データインタフェース・ユニット)、DR(データレコーダ)、TDPU(テレメトリデータ処理ユニット)、Rx(受信器)、Tx(発振器)および誘導コイルから成るが、これら各機器の仕様を決定した。NDASの機構系のうちDIUおよびDRのドロワ、およびラック装備品のうちVFEU(海水型前庭機能実験装置)、DIUおよびDRの支持金具について詳細設計を行った。さらにVFEUフィッシュパッケージ水槽試作モデルなどを用い、ガマアンコウの飼育に関して、搭載モデルに反映するための基礎データの取得を目的とする以下の試験を実施した。水質維持検証試験、刺激方法確認試験、異常時影響確認試験、装置洗浄・保管方法確認試験およびシリンジ搭載条件確認試験。またNDAS試作モデルを用い、単体機能試験および航空機実験を実施した。

In article the modern condition of questions, on systems of remote electronic diagnostics is analysed, the interrelation of remote electronic diagnostics with process of maintenance service of cars is considered.Opportunities of remote electronic diagnostics of automobile systems, and advantages of this type of diagnostics during maintenance service and operating repair are investigated. Having considered opportunities of electronic control systems in units and units of the car while in service and close interaction with these systems during diagnostics of a condition of the car and the subsequent repair in a complex, recommendations on increase of parameters of reliability and durability of vehicles and also economic parameters of their operation are given out, is optimized of process the maintenance service, being based on the preliminary given modern methods of electronic diagnostics. The algorithm of operation the car based on the continuous control of a technical condition, the flexible rules of maintenance service and operating repair, and periodic adaptation of programs of management in units and units of the car under actual conditions of operation is developed.

Dissolved oxygen (DO) in coastal bays with frequent algal blooms can undergo significant diurnal changes. Short-term DO and algal dynamics in a sub-tropical, nitrogen-limited, marine ecosystem are studied by means of a specially designed telemetry system. The high resolution data show clearly the importance of the vertical DO structure, and its relationship with environmental variables (solar radiation, water temperature, wind, tidal current) and phytoplankton dynamics. The design, instrumentation and calibration, and operational experience of the system are described. The simple and robust system has proved useful in (i) providing continuous data for full testing of water quality models, and (ii) the planning of field experiments to study algal dynamics.
