Development of Dcetecting and Imaging System for Packed Rice

Abstract

There are about eight-hundred thousand tons public food are collected and stored a year in Taiwan, and a batch of rice could be keep at most three years. In order to manage the public food warehouses, the administrates of Agriculture and Food Agency(AFA) will do a casual spot check in every barn to see if the public food spoils or is stolen and sold. Because the process of spot check is very time-consuming and sweaty, under the commission of AFA, we develop a device that can detect if any foreign body exists in the barn. In the past, some people used foreign matter, such as rice husk, boards or irons, to be instead of the paddy and cover with sheathings, so most inspectors could not get the inspection result with great precision just by their experiences. They should expend lots of manpower to check all barns. However, some fluke guys miss checking. This research is to develop the detective and photographic device of packed rice for the government paddy warehouse. The device can estimate if any foreign matter exists by the probe resistance rate of increasing, and takes the image of the foreign matter. This image is just as the direct witness.

台灣公糧存放量將近八十萬公噸，且存放時間約為3年，其間曾發生將稻穀便賣等情形，以稻殼、木板或鐵架等異物替代存放，因此農糧署人員需不定期進行稽查，稽查人員在外觀上無法判斷是否有盜賣，大都以經驗法則去判斷是否有被盜賣情形，再以人力進行清倉檢驗，需耗費甚大的人力資源，而且經驗法則的成功率甚低，使盜賣情形仍時有發生。 為了協助稽查本研究欲研製稻穀層探測及攝影設備，可以經由稻穀層探測的阻力曲線圖判斷是否有異物的存在，當碰觸硬物時也可以經由曲線自動的警示及判斷異物，於鑽探過程中利用鑽探影像擷取設備，將鑽探過程即時顯示在螢幕上，當查覺出異物時即可將影像擷取儲存作為最直接的證物。
