Micro Control Unit

This device uses GPS module to sample the data, and transmits data with the wireless module. The handheld terminals can display information such as longitude, latitude, time independently. The transmitting section collects data which is parsed and processed by the MCU, and displays it on the Liquid Crystal Display (LCD). The receiver receives and analyses wireless data, then displays the data including the current geographic information through the upper machine at the same time. Experiments show that the device could realize the function of positioning and transferring information within 200 meters and we could also use Google Map, the PC software, to get map information. This device, compared with the traditional system, is small in size, light in weight, easy carrying and can accurately position an object. It can be widely used in the sphere of investigation, exploration, navigation and positioning.

Minimum System

A wide variety of current embedded microcontrollers like 8,16 and 32-bit of Freescale Micro Control Unit(MCU) performance is stable and various. Mc9s12xs128 is a kind of Freescale 16-bit microcontroller. The concept of the Freescale Microcontroller Minimum System and the principle of realization is systematically elaborated. Many peripheral module such as Serial Communication, Liquid Crystal Display(LCD), keyboard scanning and Digital Tube Display are developed after a thorough understanding of the basic theory of Minimum System. In addition to this work, a very detailed description of each module's hardware design and software programming methodology is also made to show that an embedded system can achieve a specific function.

Micro Control Unit

The intelligentizing of sensor has been an important trend for sensor technology in recent years. In this paper, the new structure of the intelligent color scale sensor is presented; especially the software system design of intelligent color scale sensor based on the photoelectric measurement is given in detail. By using the control system based on Micro Control Unit (MCU), which takes full advantage of the resources on MCU, a new digital intelligent color scale sensor is successfully developed at a lower cost. Also, it has an ideal performance on the key index such as sensitivity, detection accuracy, response speed, reliability, operability and degrees of protection.

Sistem kontrol pengisian air otomatis dengan dua sumber suplai berbasis mikrokontroler merupakan sebuah sistem yang dapat digunakan untuk mengendalikan level air pada sebuah bak penampungan secara otomatis. Bahan dan alat yang digunakan dalam sistem kontrol berupa mikrokontroler ATmega 8535, sensor air, downloader DI-USB AVR ISP V2/DI-USB to Serial TTL, liquid crystal display, transisor, resistor, pompa air, adaptor 12 volt dc, saklar, dan program editor code vision avr. Metode yang digunakan dalam pembuatan sistem kontrol pengisian air otomatis ini adalah melakukan percobaan dan ujicoba peralatan secara langsung. Sistem kontrol ini bekerja dalam dua kondisi yaitu ketika air dalam bak penampungan melewati batas bawah maka bak penampungan akan terisi secara otomatis dan ketika telah mencapai batas atas yang ditentukan maka suplai air ke bak penampungan akan berhenti, selanjutnya ditambah pengaturan dari dua buah sumber air sebagai suplai yang akan bekerja sesuai dengan prioritasnya. Proses tersebut dilakukan oleh sensor bagian input yang berupa sensor air pada masukan sumber air yang kemudian diproses oleh mikrokontroler terprogram. Hasil percobaan menunjukkan sensor air berhasil memberikan logika Low atau High pada keluarannya sebagai fungsinya untuk memberikan sinyal masukan pada port mikrokontrol. Pada kondisi high, sensor air mampu memberikan nilai tegangan 4,89 Volt DC untuk digunakan sebagai masukan mikrokontroler. Dan pada kondisi low, sensor air mampu memberikan nilai tegangan 0,11 Volt dc sebagai masukan mikrokontroler ketika elektroda tehubung dengan common oleh media air. Driver Masukan terbukti dapat digunakan untuk menggendalikan kerja dari motor pompa 220 V AC dan lampu indikator 12 V DC. Hasil yang dari sistem kontrol pengisian air ini adalah terjadinya pengurangan kerugian yang ditimbulkan karena masalah ketersediaan air dan juga mempermudah kegiatan dalam pengendalian ketersediaan air. Kata kunci : Sistem kontrol, pengisan air otomatis, mikrokontroler, sensor air.
