The display mode of volume and sales on main display board adopt 6 digits liquid crystal display (Model ED-139, see Diagram 3-11), PPU or unit price r digits LCD (Model ED-830, see Diagram 3-12).

The drive circuit of liquid crystal display is composed of double D trigger 74HC74 and double input exclusive-OR gate 74HC86. Some fuel dispensers adopt special crystal drive circuit fuel dispenser in liquid crystal display, its principle basically similar to 74 series LCD drive circuit. A few fuel dispenser manufacturers adopt light-emitting diode (LED) as display components of display board because its cost is low and need not backlight in evening. The defect of this display component is bad display effect, especially under extensive sunlight, and much electricity consumption. LED display drive circuit also has parallel and serial drive, similar to LCD display drive circuit in terms of structure. Very few fuel dispensers adopt matrix or color liquid crystal display, showing much information. However, it largely increases cost. 2.4 Power supply Stable voltage power supply used in explosion-proof fuel dispenser Most of fuel dispensers adopt explosion-proof type, installing liner stable voltage power supply or switch voltage power supply. Switch voltage stabilizing power supply includes power transformer, DC/DC converter, 220V direct commute and pulse transformer, illustrate fuel dispenser d in Diagram 3-14 and 3-15. Due to cost-efficient and simple design, liner stable voltage power is widely adopted. However, it is affected by exterior network voltage. Although pulse transformer is able to tackle with network voltage fluctuation, it is can’t afford because of complicated technology, expensive cost and difficult to maintenance.

    dition Some healthy competition could be good for the UN s cultural agency FOR the city fathers of Kaiping in southern China—whose environs are dotted with amazing fortified mansions, mostly built in the early 20th century—the coming year could be a time to pop champagne corks. There is a similar nervous excitement at the Sydney Opera House, in the French city of Bordeaux and on the Greek island of Corfu. All these places have been proposed for recognition as “world heritage sites�by UNESCO, the cultural arm of the United Nations. Almost any location—a building, an entire city or a slice of nature can be considered for this status, which implies w fuel dispenser orld acknowledgment that it is important to humanity and worth looking after. For host governments and locals, recognition brings prestige, tourism and technical aid. But there are already 830 such sites, and the currency will be debased if the number rises too fast. In theory, any government in the world can make up to two nominations—one a man-made site, the other a natural one—per year. In practice, new recognitions per year are held at an average of 20 to 25. Even at that rate, there is a risk of overload. A modest 80 people work at the Paris office of UNESCO s World Heritage Centre; its annual budget is $9m. On the (perhaps generous) assumption that it makes sense for one agency to oversee the world s most important places, can those modest resources� however well managed—make any difference? In practice, non-government funding helps out already. The Paris Centre receives another $20m-25m per year in what it calls extra-budgetary funds, to which the biggest private do fuel dispenser nor is the United Nations Foundation, set up by Ted Turner, an American tycoon. Then there are some private agencies that try to do the same job as UNESCO on a smaller scale. One is the New York-based World Monuments Fund, which shames the planet s vandals by listing sites threatened by neglect or conflict. (UNESCO also publishes lists of endan fuel dispenser
