ow pulse from sensor and calculating data. The measuring CPU exchanges and controls data or information through the process circuit of communication signal and center-control com fuel dispenser puter. EEPROM: generally, fuel fuel dispenser dispenser adopts model 24C16 of EEPROM, which is used for memorizing calculated information, unit price, oil density, etc. The IC chip matched with measuring CPU mainly has the memory chip of calculating data, like HX1215 and 24C16. 2.2 Keyboard At present, there are two types of keyboard used on fuel dispenser, parallel scan keyboard and serial scan keyboard. Different manufacturers employ various model keyboards with these logical units that illustrated in Diagram 3-2, 3-3 and 3-4 in their fuel dispensers. Diagram 3-2: Keyboard sketch map of fuel dispenser Diagram 3-3: St fuel dispenser ructural sketch map of parallel keyboard Diagram 3-4: Structure sketch map of serial keyboard Liquid crystal displays are adopted in keyboard screen and main display screen on which showing unit price, volume and sales. The components installed on keyboard varied largely, some manufacturers adopting touch switch, others membrane key or rubber keyboard. Parallel keyboard, high speed with many lines, is restricted by data signal length due to interference. However, serial keyboard with high anti-jamming and few lines is much freer from the length of data line. Both serial keyboard and parallel keyboard are feasible plans. 2.3 Main display screen Liquid crystal display (LCD) is generally adopted as main display board of fuel dispenser recently because it is clean and beautiful in sunlight. In order to be visible at night, transparent or semi-transparent liquid crystal screen is adopted against matrix backlight board with light-emitting diode, which also have hearting function. Display usually adopts 6-6-4 type illustrated in Diagram 3-5, showing 6 digits on volume and money, 4 digits on unit price, each item data has two digits after decimal point. Display mode of display board of fuel dispenser The following are fo
