Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The intelligent network of the soft switch of employing electronics of the present utility model is handed billing machine, its structure intelligent network hand-hold billing machine comprises master control system 1, display module 2, keyboard 3, print module 4, power module 5, communication module 6, display module 2, keyboard 3, print module 4, power module 5, communication module 6 all are connected with master control system 1, power module 5 is connected with display module 2, also comprise the soft switch 7 of electronics, the soft switch 7 of electronics is connected with power module 5 and master control system 1.
The soft switch 7 of electronics comprises double D trigger 8, power transfer module 9, power button 10, MCU11, power supply control pliotron 12, power transfer module 9, power button 10, MCU11, power supply control pliotron 12 all are connected to double D trigger 8, power transfer module 9 is connected with power supply control pliotron 12, power transfer module 9 is connected with MCU11, and power button 10 is connected with MCU11.
Power module 5 is connected with the power transfer module 9 of the soft switch 7 of electronics, and the power supply control pliotron 12 of the soft switch 7 of electronics is connected with master control system 1.
When power module 5 input ends powered on, power transfer module 9 was double D trigger 8 power supplies simultaneously.Double D trigger 8 the 4th pin powers on, and double D trigger 8 the 6th pin is low level.According to double D trigger 8 transformation rules, then double D trigger 8 the 1st pin and the 11st pin are low level.Double D trigger 8 the 12nd pin is high level, and the 13rd pin is low level.Power supply control pliotron 12 is in closed condition.Press double D trigger 8 the 13rd pin state turnover when power button 10, transfer high level driving power control pliotron 12 to and open.System begins to power on.Double D trigger 8 is then controlled in the MCU11 startup keeps double D trigger 8 the 13rd pin state.Make power supply control pliotron 12 be held open state.MCU11 control double D trigger 8 makes the 13rd pin output low level, powered-down control pliotron 12.The power supply of realization shutdown system.MCU11 detects power button 10 level states and judges whether that button presses, and presses when detecting power button 10, judges 10 retention times of power button.Then machine system enters dormant state in short-term.Detect power button again by 10 times, then return running status.Pressing (keeping 3 seconds) for a long time then enters shutdown mode.Preserve data, close the machine system power supply.
The intelligent network of the soft switch of employing electronics of the present utility model is handed billing machine, except the described technical characterictic of instructions, is the known technology of those skilled in the art.
