Description
Technical field
The present invention relates to a kind of radio input device (similarly being Wireless Keyboard, mouse, Trackpad), particularly relate to a kind of can the switching and support the radio input device that different main frames are imported demands.
Background technology
In modern information society, various data, data, audio-visual message can both exchange fast with the form of electric signal, transmit, manage.And various electronic installation that is used for the access electric signal also just becomes one of most important hardware foundation of modern information society.Similarly be electronic installations such as mobile phone, personal digital aid (PDA) (PDA, personal digital assistant), mobile computer and personal computer, all widely popular widespread usage.Flourish along with semiconductor technology significantly reduced the cost of these electronic installations; Same user also can have a plurality of different electronic installations, to utilize the characteristic of different electronic installations, makes things convenient for the data access of daily life.For instance, personal computer has the highest operation efficiency usually, and mobile computer has higher portability; Personal digital aid (PDA) can make things convenient for the user to carry, arrangement personal information, mobile phone then can the access wireless voice and communication network on data.
Certainly, when the user when using these electronic installations, all must come input control order or data content, to control these electronic installation access electronic bits of datas by the input interface of these electronic installations.But, different input interfaces also have different modes of operation, and the user will adapt to the mode of operation of various electronic installation input interfaces, and inconvenience is arranged in fact.And under the electronic technology of prosperity, the volume of various electronic installations is also significantly dwindled, and makes things convenient for the user to carry.Yet, the electronic installation that volume dwindles day by day, the area of input interface also dwindles thereupon, and preferable input interface can't be provided.For instance, modern mobile phone can transmit literal news in brief, also can write down, put in order data (similarly being address list, individual stroke data) of cellie individual or the like, but the input interface of mobile phone is less, and the button that can hold is also less; Not only to use the special input method could input data, also can't take into account comfortable smooth and easy in user's use.Though personal digital aid (PDA) can allow the user with the handwriting mode input data, the correct discrimination power of hand-written data is limited, also is not suitable for being used for importing efficiently great mass of data.In comparison, the keyboard as input interface in personal computer, mobile computer just relatively meets ergonomics, also can allow the user import a large amount of data fast, expeditiously.It's a pity, in existing technology, though wired multiplexer can allow two main frames share identical input interface, but way is not further integrated the input interface of different electronic installations, allows the user still must yield to different electronic installations other input interface and input mode.
Please refer to Fig. 1.Fig. 1 is in the known technology with a wired multiplexer 12 and allows the shared keyboard 16 of two main frame 14A, 14B in the electronic system 10 as the function block schematic diagram of input interface.Main frame 14A, 14B wherein are respectively equipped with storer (similarly being random access memory) 24A and the 24B of a processing module 18A and 18B, volatibility as two electronic installations, and non-volatile storage device (similarly being Winchester disk drive or CD player) 26A and 26B.And be respectively equipped with processor (similarly being central processing unit) 20A, 20B among processing module 18A, the 18B, and chipset 22A, 22B.The function mode of two main frame 14A, 14B is identical, is that example illustrates with main frame 14A; Processor 20A among the main frame 14A is used for the running of master hosts 14A, and storer 24A is used for essential data, data and program during the temporary processor 20A running, and storage device 26A is used for storing relatively large data in non-volatile mode; And chipset 22A promptly is used for the contact transmission of data between management processor 20A, storer 24A and storage device 26A.Also be provided with an input port 17A (main frame 14B then is provided with input port 17B) on the main frame 14A, be used for receiving the input signal that transmits by a keyboard, so that the running of the input signal main control system 14A that processor 20A can receive according to input port 17A.In addition, have an end to be connected in keyboard 16 by transmission line 29C on the multiplexer 12, its two output port 19A, 19B then are connected in input port 17A, the 17B of main frame 14A, 14B respectively by two transmission line 29A, 29B.Multiplexer 12 functions own are exactly a simple switch, and the input signal that can optionally the user be imported by keyboard 16 under user's control transfers to main frame 14A or 14B.For instance, if the user will be to main frame 14A input data, instruction, just can control multiplexer 12 and switch to output port 19A (just as shown in fig. 1), allow the user can transfer to main frame 14A via transmission line 29C, 29A by data, the instruction of keyboard 16 inputs.Otherwise after multiplexer 12 switched to output port 19B, the user will be received by main frame 14B via transmission line 29C, 29B in instruction, the data of keyboard 16 inputs.
Though the multiplexer 12 in the known technology can allow two different main frames share a common input interface (just keyboard 16), still has the shortcoming in the use.At first, this practice will just can be reached by practical wiring (being transmission line 29A to 29C) and artificial selection, increases the inconvenience on using.In addition, the number of host that multiplexer 12 can be supported can be subjected to the restriction of multiplexer 12 hardware configuration own.For instance, a switching can not be supported the main frame of three (or more than) and share same input interface.Also have, the physical size of each main frame input port 17A, 17B also must be unified (similarly being the joint that identical size will be arranged), and this has also limited the elasticity in the known technology use.As previously mentioned, for the facility on using, the volume of various electronic installations all day by day dwindles, but the input port of unified specification to be set on the different electronic installations of small size, the opening of input port must increase the restriction in the case of electronic device design, because will certainly influence the situation that housing is subjected to stress-strain.
On the other hand, the input interface of Wireless Keyboard is arranged also in the existing known technology, just between keyboard and respective hosts with the radio swap date, allow the user can transfer to corresponding main frame in wireless mode via data, the instruction of Wireless Keyboard input.Though this Wireless Keyboard has saved transmission line, do not need the input port of entity yet, the Wireless Keyboard under the existing technology only can be used for serving the input demand of single main frame, can not support the input demand of many main frames (a plurality of electronic installation) widely.And, the shortcoming that the Wireless Keyboard under the existing technology interferes with each other in addition.For instance, a certain Wireless Keyboard A is the input interface of a host A, and another Wireless Keyboard B is the corresponding input interface of another host B, if but the position of host A, host B placement is very approaching, the user not only can transfer to host A by radio data, the instruction of keyboard A input, while also may be received mistakenly by host B, and interferes with the normal operation of host B.
Summary of the invention
Therefore, fundamental purpose of the present invention, a kind of radio input device that can support multi-section main frame (a plurality of electronic installation) will be provided exactly, unified no transmission line input interface can not only be provided between different main frames, it is data, the instruction which main frame to be received input by that the user can also freely be switched selection, and non-selected main frame is then interference-free fully.
The invention provides a kind of method of wireless input, be used for supporting with a radio input device environment of a plurality of main frames, this method comprises the following steps: that this radio input device enters a login operating mode; Upgrade the identification form in this radio input device; And this radio input device is optionally supported these main frames according to this identification form; Wherein the step of the identification of one in this radio input device of this renewal form comprises: main frame is obtained the device identification code of input media, obtain the device identification code and other relevent informations of input media at main frame after, the prompting user has searched input media, and the inquiry user whether with input media as input interface, finish the renewal of identification form at the control circuit of input media after, input media prompting user upgrades and finishes, and the user just can get back under the input service mode by operated input device.
In known technology, variously allow the user must yield to, adapt to the different input interfaces of different electronic installations as can't shared unified input interface between the electronic installation of main frame, cause the puzzlement in the use.Though also wired multiplexer can allow a fixed number main frame share same input interface in the known technology, this kind practice needs practical wiring, also lacks the elasticity in the use during practical application.Radio input device in the known technology then only can provide the service of input to single particular host, can't support the input demand of multiple main frame.
In the present invention, then be that the wireless module that can exchange radio data with same convention (protocol) is set in each main frame and an input media, with transmission, the wireless bag signal of reception.
Under unified agreement, each main frame and input media all have different identification code, and the user can be via the radio control of main frame, with the main frame identification code recording in input media.When the user will use input media to a certain particular host input instruction, data, this input media will be according to the main frame identification code that writes down in it, setting up wireless network with this main frame gets in touch, and the identification code of instruction, data and this particular host of user input is packaged in the bag, transfer out in wireless mode.And the radio module in each main frame can judge whether to abandon this bag according to the identification code in the bag after receiving wireless bag.In this particular host, because the identification code in the bag meets the identification code of itself, this particular host will be separated instruction, the data of reading in the bag, to accept these instructions, data as input; And do not setting up in other each main frames of getting in touch with input media, even these main frames can be understood bag, but because the identification code in the bag does not meet the identification code of these main frames itself, these main frames will abandon bag.So, the user just can come different main frame input instructions, data by the switching controls of single input media.
In the present invention, input media is that the input service is provided wirelessly, needn't use transmission line, does not need to be provided with the entity output port of same specification on each main frame and input media again, and is more convenient in the application.And input media of the present invention also can be supported the not main frame of determined number, and its number of host that can support depends primarily on input media itself can write down strokes main frame identification code, is not subjected to the restriction of the hardware configuration of input media own, also has more elasticity in the application.And instruction, data that the user imports by input media of the present invention also only can be received by the main frame that the user selectes, and the running of other main frames then can not be interfered.

In the present invention, the wireless module in each main frame and the input media 36 can both be supported identical wireless communication protocol (protocol), data, the signal of emission, reception radio form.Under unified wireless communication protocol, each wireless module all has a unique identification code, is used for identifying each wireless module without peer in the Wi-Fi of this agreement.Picture is in Fig. 2, and wireless module 48A, the 48B of main frame 34A, 34B just corresponds respectively to different identification code IDA, IDB (can be respectively equipped with non-volatile memory storage among wireless module 48A, the 48B, to store corresponding identification code IDA, IDB).In like manner, among the wireless module 48K of input media 36, also write down identification code IDK and the related setting of wireless module 48K itself with storage device 46K.And among the present invention, each wireless module can be supported following Wi-Fi running at least under unified wireless communication protocol:
(1) each wireless module can send, receive (and deciphering) has specific format under wireless communication protocol radio package signal.When wireless module A will transfer to wireless module B in wireless mode with a document, this document can be encapsulated as a bag, and in bag, specify the identification code of wireless module B, the transmission destination of representing this bag is wireless module B.After a wireless module is receiving a bag and smoothly it is being understood, if the identification code of appointment is not the identification code of itself in this bag, just this bag can be abandoned, ignore content wherein; Relatively, if the identification code of appointment conforms to the identification code of itself in this bag, this wireless module is just known this purpose as this bag transmission, and the data in the bag can be read, and transfers to corresponding processing module.
(2) one wireless module A can open beginning one message exchange (handshaking) program, require another wireless module B and its to set up contact (connection).Wireless module A can be in the service request bag of a specific format, and the identification code of specific radio module B so that wireless module B can receive this service request bag, and can be carried out information exchange routine with wireless module A.Wireless module A, B can pass through radio signals in the information exchange routine, intercourse the correlation parameter that radio communication is carried out, similarly be the speed of radio data transmission, the pattern of radio signals modulation or even the mode that the bag data encryption and decryption carries out, between wireless module A, B, to set up the contact of logical channel.For instance, wireless module A can coordinate specific frequency hop sequences with wireless module B, in follow-up Wi-Fi contact, wireless module A can will be transferred to the different bag of wireless module B and be modulated with different frequencies, wireless module B then can carry out demodulation with different respective frequencies to the difference bag that wireless module A transmits according to the frequency hop sequences of coordinating in advance in the information exchange routine.So, even another wireless module C that sets up contact with wireless module A also intercept transfer to the bag of wireless module B to wireless module A, wireless module C also can be because of the frequency that can't learn correct demodulation, and can not receive, understand these bags smoothly.Certainly, in information exchanging process, wireless module A, B also can further coordinate the mode that data encryption and decryption carries out, and additionally increase the security of wireless data exchange between wireless module A, B.
(3) wireless module can be in the scope that radio signals can reach, detect the situation of other wireless modules, this comprising: a wireless module A can be in the service of a specific format inquiry bag identification code of prompting wireless module A own, and under the situation of named place of destination location not, should serve the inquiry bag and transfer out in wireless mode.All receive other wireless modules of this service inquiry bag all can respond wireless module A, similarly be that identification code (and other relevent informations) itself is transferred to wireless module A with a specific service prompts bag, allow the main frame of wireless module A can know the situation of other members in the Wi-Fi (the pairing main frame of other wireless modules just).
Via above-mentioned various operating modes, between each wireless module of electronic system 30 of the present invention, just can learn the existence of other wireless modules mutually, and open the beginning information exchange routine, guarantee that by the contact that information exchange routine is set up the Bao Buhui that exchanges between two wireless modules is received, understands by other wireless module.And operation principles of the present invention, utilize getting in touch of an input media 36 and particular host foundation exactly, the data, the instruction that allow the user pass through input media 36 inputs can be received, be understood by this specific main frame with the form of radio package, and can not disturb other main frames.In input media 36, be stored in each field in the identification form 58, be used for writing down the corresponding identification code of each main frame exactly; Just as in Fig. 2, input media 36 can be supported the input to main frame 34A, 34B, and field 59A, the 59B in the identification form 58 just write down identification code IDA, the IDB of the corresponding wireless module 48A of main frame 34A, 34B, 48B respectively.Utilize identification code in the identification form, input media 36 just can be discerned each main frame 34A, 34B under same wireless communication protocol, and gets in touch data, the instruction of transmission user input with the wireless module foundation of each main frame.In other words, the identification code IDA of wireless module 48A, 48B, IDB just can be considered as representing the main frame identification code of main frame 34A, 34B respectively.Accordingly, the pairing identification code IDK of wireless module 48K of input media 36 then can be considered the device identification code of input media 36.
Please refer to Fig. 3 (and in the lump with reference to figure 2), the present invention supports the operation principles that the multi-section main frame is imported demand with single wireless input media 30, can be illustrated by the flow process among Fig. 3 100.When the user will will instruct with input media 36, during each main frame of data input, just can control input device 36 enter an input service mode, begin to carry out flow process 100.Be provided with the following step in the flow process 100:
Step 102: beginning when the user will import with input media 36, begins to carry out flow process 100 with regard to may command input media 36.
Step 103: the user selects the object main frame of its data input by the input interface 52 on the input media 36.Below the hypothesis user will by input media 36 with data input to main frame 34A, then the user just can control input interface 52, to discern the identification code IDA that is recorded in field 59A in the form 58 by input interface and read, and represent the identification code IDA of main frame 34A to transfer to control circuit 50 this.
Step 104: according to the identification code IDA that input interface 52 transmits, control circuit 50 just can be controlled wireless module 48K and open information exchange routine between beginning and main frame 34A, gets in touch with main frame 34A foundation.Described as the front, wireless module 48K can send the service request bag according to identification code IDA, requires the wireless module 48A of main frame 34A to carry out information exchange routine with it, sets up contact.
Step 106: after in step 104, setting up getting in touch of Wi-Fi with main frame 34A, the user just can be converted to controlling signal 56A (please refer to Fig. 2) by input interface 52 by instruction, the data of input interface 52 inputs on input media 36, and control circuit 50 just can be encoded controlling signal 56A, be converted to controlling signal 56B, and together be packaged in the data bag 60 together with the identification code IDA of main frame 34A, by getting in touch that wireless module 48K and main frame 34A set up, data bag 60 is transferred among the main frame 34A in wireless mode again.Though main frame 34B (or other not specific main frames, wireless module) also might receive data bag 60, but because of the wireless module 48A that has indicated in the data bag 60 with main frame 34A is the purpose of data transmission, the wireless module of other main frames all can abandon data bag 60.Especially bad, as previously mentioned, other main frame also may can't be understood data bag 60 fully, because the getting in touch through further encrypting or specific modulation (similarly being aforesaid frequency hopping) of 36 of main frame 34A and input medias.By this way, the present invention just can guarantee that the user only can transfer to the main frame that the user selects by instruction, the data of input media 36 inputs, and can not influence, disturb other main frame.
After input media 36 and main frame 34A foundation are got in touch, input media 36 also can be in data bag 60 during with information exchange routine and the code name coordinated in advance of main frame 34A to indicate the transmission destination of data bag 60 be main frame 34A, and needn't in data bag 60, directly indicate the transmission destination of data bag 60 with the identification code IDA of main frame 34A.Especially when getting in touch of 36 of main frame 34A and input medias passed through aforesaid encryption or specific modulation, since it is unique and can not disturb other main frames that input media 36 can have been guaranteed the logical communication link between itself and main frame 34A, input media 36 just can be simplified the data structure of data bag 60.
Step 108: if the main frame that the user does not reelect other by input interface 52 is as input object, input media 36 will be got back to step 106, the contact of continuation to set up in the step 104 allows the user wirelessly data, instruction be inputed to main frame 34A.Input finishes if the user is to main frame 34A, and data, instruction will be changed when inputing to main frame 34B, and the user just can control input interface 52, and the identification code IDB that changes main frame 34B correspondence transfers to control circuit 50.
Step 110: the user switch by input interface 52 with main frame 34B as input object after, the control circuit 50 in the input media 36 just breaks contact with the main frame 34A that originally got in touch.Control circuit 50 may command wireless module 48K send specific bag, and notice main frame 34A will break contact with it.Next flow process 100 will be back to step 104, carries out information exchange routine with main frame 34B again by input media 36; Set up finishing with the information exchange routine of main frame 34B get in touch after, the user just can pass through the input interface 52 of input media 36, will instruct, data input is to main frame 34B.
As seen from the above description, input media 36 of the present invention can not only provide wireless input interface, avoids the trouble of actual arrangement transmission line, also is not subjected to the restriction of input media 36 hardware configuration own, can support the input demand of multi-section main frame widely.Because input media 36 is the main frame identification codes that obtained each main frame by the identification form 58 that writes down among the storage device 48K, as long as have enough memory capacity to write down different main frame identification codes among the storage device 48K, input media 36 just can be supported the input demand of a plurality of main frames.For instance, if write down ten main frame identification codes in the identification form 58, the user just can be with input media 36 as unified input interface, and switching is input into ten different types of main frames.
On the other hand, in the present invention, the user also can freely upgrade, edit the identification form that stores in the input media 36.For instance, example in the extension bitmap 2, if the user wishes by input media 36 to another main frame input, and the identification code of this main frame is not recorded in the identification form 58 as yet, the user just can enter a login operating mode by operated input device 36, so that upgrade identification form 58, support input to this main frame.About this situation, please refer to Fig. 4 A, 4B.Fig. 4 A be among Fig. 2 electronic system 30 after adding in addition a new main frame 34C, each the device function block schematic diagram (for accompanying drawing for purpose of brevity, under the situation that does not hinder the technology of the present invention to disclose, omitted the function square of part among main frame 34A, the 34B among Fig. 4 A); And the flow process 200 shown in Fig. 4 B is input media 36 and cooperates main frame 34C to discern form 58 under a login operating mode to upgrade each step of being carried out.Shown in Fig. 4 A, also be provided with the storer 45C of processing module 38C, volatibility, non-volatile storage device 46C and a wireless module 48C among the main frame 34C.Under the radio communication agreement identical with wireless module 48A, 48C and 48K, wireless module 48C is also corresponding to a unique identification code IDC; This also just becomes the main frame identification code of main frame 34C.
When main frame 34C has just begun to be added to electronic system 30, the identification code of main frame 34C is not added in the identification form 58 of input media 36 as yet, just as shown in Fig. 2.Upgrade identification form 58, user's may command input media 36 enters the login operating mode, to carry out the flow process 200 among Fig. 4 B, cooperates main frame 34C to discern the renewal of form 58.Flow process 200 among Fig. 4 B has the following step:
Step 202: beginning
Step 204: main frame 34C obtains the device identification code IDK of input media 36.Main frame 34C can obtain the identification code IDK of input media 36 via several different modes.For instance, main frame 34C can send wireless service inquiry bag (the identification code IDC that comprises main frame 34C itself in it), and other wireless modules that require to receive service inquiry bag are responded; And input media 36 is after entering the login operating mode, input media 36 identification code IDK own will be packaged in the service prompts bag of a specific format together with other information (similarly being 36 information as an input interface of display input device), and the identification code IDC that transmits with main frame 34C in this service prompts bag is as transmission destination, so that make main frame 34C can receive this service prompts bag; And main frame 34C just can obtain the device identification code IDK of input media 36 after receiving this service prompts bag.
Except above-mentioned embodiment, also can itself initiatively send the service prompts bag of specific format by input media 36.Input media 36 can be periodically sends the service prompts bag that includes input media 36 identification codes own in the mode of assigned address not when carrying out flow process 200, allow main frame 34C can obtain the device identification code of input media 36.
In this step, main frame 34C also can carry out information exchange routine with input media 36 behind the device identification code IDK that obtains input media 36, sets up contact.
