Describe technical scheme of the present invention in detail below in conjunction with the drawings and specific embodiments.
Referring to shown in Figure 1, the multi-screen personal digital assistant of present embodiment comprises main personal digital assistant unit 101 and sub-personal digital assistant unit 102 two parts.Main personal digital assistant unit 101 comprises host process unit 103, host interface module 104 and main frame display unit 105.Sub-personal digital assistant 102 comprises handset control module 106, handset display unit 107 and handset interface module 108.Wherein, host process unit 103, be used to receive the host subscriber and select signal and provide displaying contents to main frame display module 105, and receive handset user selection signal that host interface unit 104 transmits and provide displaying contents to host interface unit 104 according to this handset user selection signal according to host subscriber's selection signal; Main frame display unit 105 shows the content that host process unit 103 provides; Host interface unit 104 receives the control signal from handset interface unit 108; Handset interface unit 108, to the control signal of host interface unit 104 forwarding handset control modules, and the displaying contents that provides to handset display unit 107 forwarding host process unit 103; Handset control module 106 is used to accept user's selection signals and according to selecting signal to transmit control signal to handset interface unit 108; Handset display unit 107 shows the information content from handset interface unit 108.Here, interface unit can be wireless communication module or wireline interface.Wireless communication module can be bluetooth module, WIFI module or infrared module.Wireline interface can be serial ports, parallel port or USB interface etc.The handset control module can be roller or button.
Referring to shown in Figure 2, the host process cell processing is as follows from the detailed process of handset control signal:
Step 201: main personal digital assistant enters the wait solicited status.
Step 202: main personal digital assistant is received the pairing request that sub-personal digital assistant sends.
Step 203: main personal digital assistant judges whether and can match, if can, then carry out 204, otherwise, execution in step 201.
Step 204: main personal digital assistant is sent to sub-personal digital assistant with bibliography data, waits for the affirmation information of sub-personal digital assistant;
Step 205: receive the affirmation information of selection bibliography of sub-personal digital assistant when main personal digital assistant after, the homepage data of selected book are sent to sub-personal digital assistant.
Step 206: if main personal digital assistant is received sub-personal digital assistant request, judge request type,, send next page data to sub-personal digital assistant if this request is page turning; If this request is redirect, then execution in step 204.
Be that bluetooth communication is that example is further set forth multi-screen personal digital assistant of the present invention below with the interface module.
Referring to shown in Figure 3, the multi-screen personal digital assistant comprises main personal digital assistant unit 101 and sub-personal digital assistant unit 102.Further, sub-personal digital assistant unit 102 comprises handset control module 106, handset display unit 107 and handset bluetooth module 308.Main personal digital assistant unit 101 comprises main frame bluetooth module 304, host process unit 103 and main frame display unit 105.
After group personal digital assistant unit 102 powers on, the user transmits control signal to handset bluetooth module 308 by handset control module 102, after handset bluetooth module 308 is received this control signal, this control signal is sent to main frame bluetooth module 304, and main frame bluetooth module 304 is forwarded to host process unit 103 with this control signal again.After this control signal is received in host process unit 103, judge whether sub-personal digital assistant and self mate, if coupling then offers handset display unit displaying contents by main frame bluetooth module and handset bluetooth module.
Handset user can pass through handset control module 106, select according to handset display unit content displayed, what handset bluetooth module 308, main frame bluetooth module 304 transmitted handset control modules 102 controls signal to host process unit 103, host process unit 103 provides content according to the control signal of handset, and the content that provides is sent to 107 demonstrations of handset display unit by main frame bluetooth module 304 and handset bluetooth module 308.
From said process as can be seen, when not using sub-personal digital assistant,, can sub-personal digital assistant be set to closed condition for saving electric power.When needs use sub-personal digital assistant, initiate pairing by handset, the response of host pairing.After successful matching, main personal digital assistant will offer sub-personal digital assistant menu and show, handset user can select book and definite by roller or button.Selection result will be sent to host side by bluetooth module, the handling procedure of host side by analysis after, send corresponding data to sub-personal digital assistant, show selected personal digital assistant content on the sub-personal digital assistant thereupon.By in the handset user reading process, can carry out page turning by roller and button, host side will in time respond various buttons, send desired data to outer hanging panel and show.If handset user thinks to select again book, can select again by the master menu that roller or button access storage inside.After finishing using, can close sub-personal digital assistant unit, all device outages.The dormancy of main frame bluetooth module, handling procedure is closed, and other parts of multi-screen personal digital assistant are work as usual.
Present embodiment respectively has a bluetooth module on main frame and handset, data are wireless transmission between two bluetooth modules just.Bluetooth module is received the processing unit analyzing and processing of handing to again after the data separately.Main personal digital assistant is responsible for handling the personal digital assistant of two different pages.A page is the same with at present general personal digital assistant program, is responsible for the demonstration of main personal digital assistant; Another page is responsible for the demonstration of sub-personal digital assistant.Outside main personal digital assistant receives from sub-personal digital assistant, after the request, after judging, send corresponding data to sub-personal digital assistant by bluetooth module and show.Sub-personal digital assistant also has a button that is used for simply controlling or roller except that LCDs, battery and bluetooth module, carry out simple control, comprises necessary control such as selecting book, page turning, and then realizes not relying on the independent control of main frame.
In real process, also can realize multi-screen personal digital assistant of the present invention with original personal digital terminal by expansion.Such as, personal digital terminal can increase bluetooth equipment by expansion, such as by serial ports, USB, PCMCIA, SD etc., moves handling procedure then, realizes sharing personal digital assistant.
