Abstract
The utility model discloses a POS machine with an overvoltage protector. The POS machine comprises a power supply, a master control module, the overvoltage protector, a man-machine interactive interface and a display screen. The man-machine interactive interface and the display screen are respectively connected with the master control module. The power supply supplies power for the master control module. The overvoltage protector is connected with the master control module. The master control module is used to receive data information of an external device through the man-machine interactive interface, and outputs the data information to the display screen after split screen conversion. An embodiment of the utility model uses the master control module to convert the data information in a split manner and then outputs the data information by the display screen, so two textboxes can be displayed on a same screen, thereby saving hardware cost.
Description
Technical field
The utility model relates to POS machine technology field, is specifically related to a kind of POS machine with band over-pressure safety device.
Background technology
Conventional P OS machine adopts two screens mostly on the market now, and relevant informations such as dealing money are shown to aspectant operating personnel respectively, and the client.Adopt two screens to show relevant information respectively at POS terminal facility, increased hardware cost on the one hand, in addition on the one hand owing to adopted two screens to strengthen the difficulty of hardware design.
The utility model content
The utility model provides a kind of POS machine with over-pressure safety device, can address the above problem.
A kind of POS machine with over-pressure safety device that the utility model provides, comprise power supply, main control module, over-pressure safety device, Man Machine Interface and display screen, described Man Machine Interface links to each other with main control module respectively with display screen, and described power supply is the main control module power supply; Described over-pressure safety device comprises detection control apparatus and switchgear, and wherein switchgear is connected between civil power and the protected electrical equipment; Wherein detection control apparatus comprises integrated resistor, diode and a triode; Described integrated resistor and back-biased diode are connected in turn between the base stage and emitter of triode; Described over-pressure safety device is connected with described main control module; Described main control module is used for receiving by Man Machine Interface the data message of external unit, and data message is carried out exporting display screen to after the split screen conversion.
Preferably, described main control module comprises microprocessor chip, data storage cell and picture segmentation chip, described data storage cell and picture segmentation chip are connected respectively to microprocessor chip, and described Man Machine Interface is connected microprocessor chip respectively with display screen.
Preferably, also comprise keyboard, described keyboard is connected to Man Machine Interface.
Technique scheme because the utility model embodiment adopts main control module that data message is carried out the split screen conversion and then by display screen output, therefore can show two text boxes at a screen, has been saved hardware cost as can be seen.
Description of drawings
Fig. 1 is the structured flowchart of POS machine among the utility model embodiment.
Embodiment
In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, describe most preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, the utility model is limited.
Shown in Fig. 1, a kind of POS machine with over-pressure safety device that the utility model provides, comprise power supply, main control module 1, over-pressure safety device 5, Man Machine Interface 3 and display screen 8, described Man Machine Interface 3 links to each other with main control module 1 respectively with display screen 8, and described power supply is main control module 1 power supply; Described over-pressure safety device 5 comprises detection control apparatus and switchgear, and wherein switchgear is connected between civil power and the protected electrical equipment; Wherein detection control apparatus comprises integrated resistor, diode and a triode; Described integrated resistor and back-biased diode are connected in turn between the base stage and emitter of triode; Described over-pressure safety device 5 is connected with described main control module 1; Described main control module 1 is used for receiving by Man Machine Interface 3 data message of external unit, and data message is carried out exporting display screen 8 to after the split screen conversion.
Particularly, described main control module 1 comprises microprocessor chip 6, data storage cell 4 and picture segmentation chip 7, described data storage cell 4 and picture segmentation chip 7 are connected respectively to microprocessor chip 6, and described Man Machine Interface 3 is connected microprocessor chip 6 respectively with display screen 8.
Usually the POS machine all is provided with operation keyboard, so the POS machine also comprises keyboard 2 among the utility model embodiment, and described keyboard 2 is connected to Man Machine Interface 3.
Introduce the principle of work of the POS machine of the band over-pressure safety device that the utility model embodiment provides below in conjunction with Fig. 1.
Man Machine Interface is that computing machine is with the control circuit of realization information transmission between the human-computer interaction device.It finishes two tasks that information forms conversion and transfer rate coupling with the human-computer interaction device.The human-computer interaction device has comprised mouse, keyboard, printer etc.Human-computer interaction device among the utility model embodiment is keyboard, and operating personnel can import dealing money and inquire about other Transaction Informations by keyboard.As operating personnel during in the operation of the enterprising line correlation of keyboard, data message is transferred to main control module through Man Machine Interface, the microprocessor chip of main control module arrives data storage cell with this data information memory, in order to call at any time and change, microprocessor chip is transferred to the picture segmentation chip through conversion after data message is accessed by data storage cell, the picture segmentation chip carries out the split screen conversion with data message, exports to display screen then and carries out the double screen demonstration.Thereby realized showing on the screen effect of two text boxes, when the consumption amount of money of importing from keyboard as operating personnel is ten yuan, should show on the display screen and " consume ten yuan, please swipe the card ", because operating personnel and consumer are face-to-face, therefore the text need be segmented in two text boxes that are mutually inverted image and show, therefore, just can demonstrate on the display screen of the POS machine in the utility model embodiment.
The above embodiment only is used for illustrating the utility model, but is not limited thereto.Under the condition that does not depart from the utility model design, affiliated technical field personnel can make suitable change adjustment, and these change adjustment also should be included within the claim protection domain of the present utility model.
