METHOD OF RECEIVING AND REFRESHING ORDER IN DRIVING SERVICE AND QUICK-SERVICE MAN

摘要

A method for automatically preoccupying an order/inquiry of a proxy driver and a quick-service man is provided to reduce fatigue of the eyes remarkably by preoccupying the order simultaneously with a click sound of an order window without making the driving agent and the quick-service man view the order window of a PDA for a long time. An order/inquiry is automatically preoccupied by operating an oscillation indication LED(Light Emitting Diode) lamp(208) with pulse generated from an oscillator circuit(204) and, at the same time, connecting with an order or inquiry key(207) of the PDA or a mobile phone(201) as a signal is provided to a power separation interface(206) through a pulse amplifier(205). The order or inquiry key is simultaneously operated with flickering an operation indication LED by installing an external order key driver to the PDA or the mobile phone, and providing the signal to an external order or inquiry key oscillating module circuit through a 24-pin power terminal(202), a driver terminal, and a power supply switch(203).
