title: A Kind of Multi Channel Priority Control Device for Greenhouse Roller Shutter Machine
abstract: The greenhouse roller shutter machines available mostly are pointing controlled through motor, existing the security problems like easy falling of heat preserving curtain rolled up. This paper presents a kind of multi channel priority control device for greenhouse roller shutter machine, achiving the multi channel control which contains limit control, manual control, remote control and program control for roller shutter machine. The device could improved using safety while the system was controlled more accurately and intelligently.  The greenhouse, which is instrumental in breeding the anti season vegetables, shortening the growth cycle of crops and improving the crops survival rate, has important significance in the development of agricultural production. There are more and more requirements for the regulation of greenhouse environment parameters with the agricultural modernization rapidly developing and continuous expansion of the greenhouse. The roller shutter machine of greenhouse is an agricultural machinery equipment, which is designed to control the heat preserving curtain lifting  According to the researches, the incomes per mu of breeding melons, vegetables and edible fungus were more than 6,000 yuan and even up to 10,000 yuan. Particularly the great profits of anti seasonal vegetables and fruits were the key factors that farmer's enthusiasm on greenhouse crops production  Plastic greenhouse production bases were built all over the country for vegetables breeding and fresh fruit production, and the scale was increasing constantly. In the greenhouse operation, rolling up and laying the heat preserving curtain was one of the most time consuming work, especially at the early morning and evening in the winter. The work in terrible conditions was badly limited the yield profit and development space of greenhouse due to the strong labor intensity and low efficiency. The appearance of roller shutter machine met the farmer's demand for greenhouse crops production. The machine not only can solve the problem existing in manual rolling up the heat preserving curtain, but it's quick operation also makes the illumination time prolonged and crop quality improved which give farmers more energy managing crops easy. In addition, the application of roller shutter machine has a better protection for grass curtain and cotton curtain, and prolongs the service life of curtains thus cutting production costs. The Conventional Roller Shutter Machine The roller shutter machine could be divided into front machine and post machine according to the installation method, and also could be divided into electric machine and artificial machine according to the different power source. The machine most frequently using power was 220V or 380V alternating current [3] The roller shutter machines available mostly were pointing controlled through motor, and existed the security problems of falling easily of heat preserving curtain rolled up due to the imperfect control system at present. Electrical motor turned while the finger pressing the button, otherwise the motor would stop and the position of heat preserving curtain was fully determined by manual control. The phenomenon of rolled heat preserving curtain falling from the top of greenhouse was often appeared because of miscarriage of justice and the power couldn't be cut off in time, which 5th International Conference on Machinery, Materials and Computing Technology (ICMMCT 2017)

title: Design and Analysis of Shutter in Injection Molding Machine
abstract: Injection molding machines uses the process, in which hot molten plastic is injected under high pressure into a thin cold mould. There are many types of injection molding machines available in plastic processing industries according to its clamping unit. In hydraulic ram type clamping machine a component called shutter often get breakdown due to high compression force generated on it. So design and analysis of Shutter in ram type injection molding machines is used to increase the strength of shutter so it helps to reduce the failure of shutter. The aim of research is to reduce the breakdown of shutter in hydraulic ram type clamping injection molding machine.

title: Optimisation of Shutter Speed in Machine Vision Technique for Monitoring Grinding Wheel Loading
abstract: Grinding is an abrasive machining process which controls the surface finish of the materials in production of industrial components at the end stage. During the grinding process, wheel gets loaded with swarf and this loading will affect the cutting ability of the wheel and also the surface finish of the job. Hence the grinding wheel is to be dressed at appropriate time intervals and for necessary time duration. At present, the monitoring of grinding wheel loading and dressing is done by the operator i.e. the frequency of dressing and duration of dressing is determined by the operator based on his experience. Hence there arises a need to develop a systematic approach to this problem which can monitor the process and if not accurately should at least produce a realistic estimate of the percentage of wheel loading, frequency of dressing and duration of dressing. In machine vision system, Shutter speed is an important factor which will affect the image quality. Hence, in this work, attempts are made to monitor wheel loading using a low cost high speed camera with variable shutter speed and the shutter speed is optimized for the better image quality.
