Embodiment
See also shown in Figure 1ly, transfer out the portable electric device system of function, comprise and transfer out a module 121 and a transmitting device 30 (as shown in Figure 2) according to the tool screen picture of preferred embodiment of the present invention.One simulation softward 220 is installed on computer apparatus 20.
In present embodiment, portable electric device 10 comprises first display 11 and first memory 12, and 20 of computer apparatus comprise second display 21 and a second memory 22.For convenience of explanation, other element such as CPU and data transmission bus-bar etc. all is not shown among the figure.
In portable electric device 10, for example can adopt that liquid crystal display module etc. is used as first display 11,21 of second displays in the computer apparatus 20 can adopt cathode-ray tube, liquid crystal screen display or plasma display panel etc.Because portable electric device 10 is subjected to restriction on the volume, so can be less compared to the display area of second display, 21, the first displays 11 of computer apparatus 20.
See also shown in Figure 2, transmitting device 30 can adopt known transmission technology, be responsible for the data transmission between portable electric device 10 and the computer apparatus 20, it comprises a transmission medium 310 and two data transmission module 320, and wherein transmission medium 310 can be wire transmission media or wireless transmission medium; The selected of data transmission module 320 is to cooperate transmission medium 310, and is present in respectively in the second memory 22 of the first memory 12 of portable electric device 10 and computer apparatus 20.For example, transmission medium 310 can be a RS232 transmission line, and data transmission module 320 can be according to tandem communication connection standard and utilizes serial port to transmit and receive the program module of data.When the wireless transmission data of utilization bluetooth (Bluetooth) technology or IEEE 802.11, transmission medium 310 is air (Air), and 320 of data transmission modules pile up (protocolstack) for the agreement of employed wireless communication protocol.
// be installed on the application software of portable electric device
Main () ... initialization tandem port; While (TRUE) ... if (receiving the instruction that the user imports) { executes instruction and obtains an execution result; Output execution result to the first display; Module is transferred out in calling; ... the end of while of } //＜!--SIPO＜DP n=" 6 "〉--〉＜dp n=" d6 "/// transfer out module Redirect (instruction) ... check the serial port connection state; Calling data transmission module with move instruction to serial port;
Simulation softward 200 is the second memories 22 that are present in computer apparatus 20, the instruction that its simulation is transmitted by portable electric device 10, export picture to calculate a screen that corresponds to portable electric device 10, then be output in second display 12 of computer apparatus 20, make the screen output picture of second display 12 of computer apparatus 20, identical with the screen output picture of first display 11 of portable electric device 10.For example, simulation softward 220 can adopt following program architecture:
// be installed on the simulation softward of computer apparatus
Main () ... initialization tandem port; Listen attentively to serial port; If (accepting the instruction that serial port transmits into) ... reception is by instruction that serial port transmitted; Execution command; Output execution result to the second display; }＜!--SIPO＜DP n=" 7 "〉--〉＜dp n=" d7 "/
For content of the present invention is more readily understood, below will lift an example, transfer out the flow process of the method for screen picture according to the portable electric device system from tool screen picture transfers out function of preferred embodiment of the present invention with explanation.
See also shown in Figure 3, the application software 120 that is installed on portable electric device 10 is after carrying out, at first initialization tandem port 101, wait state and wait for user's input instruction in finishing that reprocessing stops, next accept the instruction 102 of user's input, after the execution command execution result is output in first display 11 (103) immediately.
Then application software 120 checks whether transfer out module 121 has started 104, if do not start as yet, process ends then, if start, then transfer out module 121 and check serial port connection states whether normal 105, after confirming that the serial port connection state is normal, transfer out module 121 just calling data transmission module 320 with move instruction to serial port, then instruction is transferred to computer apparatus 20 (106) via transmission medium 310.
Simultaneously, the simulation softward 220 that is installed on computer apparatus 20 continues to listen attentively to serial port behind initialization tandem port, if receive the instruction of being transmitted by portable electric device 10, then simulation softward 220 execution commands, and output execution result to the second display 21 (107).
Because in comparison, the data quantity of instruction size can be much smaller than the data quantity size of output picture, so computer apparatus 20 can be exported frame updating in its second display 21 with the screen that corresponds to first display 11 of portable electric device 10 immediately.So the usefulness that the screen picture of handheld electronic device 10 transfers out is transferred out System and method for and can be provided in display frame of the present invention.
The above only is an illustrative, but not is restricted.Anyly do not break away from spirit of the present invention and category, and, all should be contained in the accompanying claim its equivalent modifications of carrying out or change.
