[0012]
Embodiments and Examples of the Invention
[First Embodiment]
FIG. 1 is a diagram showing a configuration of a system using a wireless communication device 101 according to a first embodiment of the present invention.
[0013]
In this system, a wireless communication device 101 is a PC on which a wireless interface is mounted, and a communicable area 102 is a communicable area of the wireless communication device. The printers 103 and 104 are printers having a wireless interface, and the digital still camera 105 has a wireless interface. The PC 106 has the same communication function. The mobile phone 107 is a mobile phone having the same communication function.
[0014]
FIG. 3 is a diagram illustrating a basic display screen 201 of the wireless communication device 101, specifically, a diagram illustrating a desktop screen of a PC.
[0015]
The shortcut icons 202, 203, and 205 are shortcut icons having storage location information of a file in which a unique address and a device name of each wireless communication device 101 are registered.
[0016]
The communication program shortcut 204 is a communication program shortcut for performing communication using the wireless interface, and the execution screen 206 is an execution screen of the communication program.
[0017]
Next, a specific operation of the PC 101 in the above embodiment will be described.
[0018]
FIG. 2 is a flowchart illustrating an operation in which the wireless communication device 101 registers another wireless communication device.
[0019]
First, the registration setting of the wireless communication device 101 will be described.
[0020]
The user starts the communication program on the PC 101 and selects a device setting instruction (not shown) from the menu of the communication program execution screen 206 shown in FIG. When the device registration setting is selected, first, in step S100, the communication program sends a transmission instruction of an inquiry signal for searching for the wireless communication device 101 existing in the communication area 102 to the hardware of the wireless interface. Then, the flow shifts to S101, where a detection response is confirmed.
[0021]
If a response signal to the inquiry signal is received from the hardware, the process proceeds to S102, and information such as device-specific address information and name included in the detection response signal is displayed on the execution screen 206. The process shifts to S103, and checks whether or not a preset terminal detection time has elapsed.
[0022]
If the detection time has not elapsed, the process proceeds to S100, where an instruction to send an inquiry signal is sent again, and a new wireless communication device 101 is searched. This operation is repeatedly performed until a predetermined time elapses, and when the set time elapses, the process proceeds to S104, and based on the device search result, whether or not the user has performed a registered device selecting operation is monitored, and If the selection operation of the communication device 101 has not been performed, the process proceeds to S105, and it is determined whether a manual registration operation has been performed.
[0023]
Here, if the user does not select a registered device or perform an operation of a manual registration instruction, the process stands by until a user instruction is issued. In FIG. 2, since the flowchart is simplified and described, the response to the cancel operation in the middle is not described, but the registration operation can be interrupted in the middle.
[0024]
If the search result of the wireless communication device 101 is not displayed on the program execution screen 206, the user performs a manual registration instruction operation. When the manual registration instruction operation is performed, the registration setting program proceeds to S106 and displays the unique address information of the desired registered wireless communication device, the device name and the input screen of the communication function of the device to be registered, and , Waiting for information input from the user.
[0025]
Upon completion of this input, the flow shifts to S107, where a device registration process for saving the input registration information as a file is performed. Here, if the search result of the wireless communication device 101 displayed earlier includes a device desired by the user, the device is selected on the execution screen 206 and registration is instructed.
[0026]
When this registration instruction is performed, the program shifts from S104 to S107 in the same manner as above, and performs a registration process. In this registration process, the acquired device name is used as the name of the generated registration file.
[0027]
As described above, the wireless interface can communicate with various devices, and thus has a plurality of communication functions depending on the registered device. For example, it has a function having a communication protocol necessary for LAN connection, a communication protocol used for printing, a function for image transfer, file transfer, and the like.
[0028]
Therefore, in this embodiment, a configuration having a plurality of registration files for each function is possible, and a plurality of functions of the device may all be registered in one registration information file. Further, in the registration information file, at least one of the unique address information and the device name is registered, and at the time of establishing a link to be described later, a connected device is selected based on the registered unique address information, and the detected device is selected. After displaying the function list of the communication function, the target communication function may be selected.
[0029]
Upon completion of the registration process, the process shifts to S108 to wait for an instruction indicating whether to create a shortcut to the registered information file. When the user issues a shortcut creation instruction, the process proceeds to S109, and after creating a shortcut icon including information on the storage location of the registration file, the device registration setting operation ends.
[0030]
On the other hand, if the user does not issue a shortcut creation instruction, the device registration setting operation is immediately terminated. The generated shortcut is given the same name as the device name, and the name can be changed to an arbitrary name that is easy for the user to determine.
[0031]
In the present embodiment, a case is described in which a shortcut including a path to an information file of the registered wireless communication device 101 is created. However, the registration file can be stored in an easily operated location such as a desktop. . In this case, the file may be stored during registration by the device registration setting program, or after being stored in a specific area, the user himself can move the file to an arbitrary location.
[0032]
Next, the operation of establishing a wireless link with the wireless communication device 101 that has performed the registration setting in the above embodiment will be described.
[0033]
First, when a registration operation is performed in the wireless communication device 101 and a shortcut icon of a communicable wireless communication device is generated, a shortcut icon of the registered wireless communication device 101 is displayed on the desktop screen 201 as shown in FIG. Icons 202, 203, and 205 are arranged.
[0034]
FIG. 4 is a flowchart illustrating an internal process when the wireless communication device 101 performs an operation of communicating with another registered wireless communication device in the above embodiment.
[0035]
When the user drags the icon 205 indicating the PC in the office among the icons arranged on the desktop screen 201 and drops the icon 205 on the shortcut icon 204 to the communication program, the control program of the wireless communication device 101 As an internal process, the process proceeds to step S201 shown in FIG. 4, and the communication program is started. When the start of the communication program is completed, the process proceeds to step S202, an instruction for transmitting an inquiry signal is issued to the communication program, and the process proceeds to step S203.
[0036]
Upon receiving the inquiry signal transmission instruction, the communication program sends an inquiry signal for searching for the same type of wireless communication device existing in the communication area 102 of the wireless communication device 101 to the communication area 102, and outputs a detection response signal Is received, a detection result is returned to the control program, and the transmission operation of the inquiry signal is continued until a preset detection time elapses.
[0037]
When the inquiry signal is transmitted in the communication area 102 shown in FIG. 1, the communication program can always obtain a response to the detection signal from all wireless communication devices depending on the radio wave environment and other factors. Although not limited, it is possible to obtain five types of response signals of the two printers 103 and 104, the digital still camera 105, the portable terminal device 107, and the PC 106. When each of the response signals is obtained, the communication program becomes The above information is returned to the control program in the order in which the responses were received.
[0038]
The control program that has proceeded to step S203, proceeds to step S204, checks whether or not there is a detection response signal from the communication program, and upon receiving this device detection response signal from the communication program, once proceeds to step S205, where the detection terminal After the information is stored, it is determined in step S206 whether or not the device detection time of the communication area has elapsed. If the time has not elapsed, the process returns to step S203, and the operation of storing a new detection result is repeated. .
[0039]
If it is determined that the device detection time has elapsed, the control program sends an instruction to the communication program to detect the device name and the communication function of the device (S207). This operation is repeated until the detailed information of all the detected devices is obtained (S208).
[0040]
When these series of operations are completed, the control program proceeds to step S209, where the unique address information of the device detected by sending the inquiry signal and the unique address registered in the previously dragged and dropped registration information are registered. The information is collated, and if it is determined that the wireless communication device having the matching address is detected (S210), the process proceeds to step S211 to check the function registered in the registration information and the communication function acquired earlier. It is determined whether or not the information matches.
[0041]
Here, if the registered unique addresses or the communication functions do not match, the process proceeds to step S212, error information is displayed, and the communication operation is interrupted.
[0042]
Further, when the information detected by each detection operation and the registration information for which the connection request has been made all match, a physical link is first established based on the registration information, and then the function specified by the communication function is used. To establish a link for the upper protocol.
[0043]
Specifically, when the wireless communication device selected in the present embodiment is the PC 205 and the function registered in the PC 205 is a LAN connection, a physical connection of the wireless interface is first established, and thereafter, Then, after performing an operation of confirming the function of the device and performing an authentication operation as necessary, a logical link is established to a layer in which operation of a higher-level protocol (eg, a communication protocol such as TCP / IP) can be guaranteed. When these links are established, the operation of the link connection control program ends, and an application operation for performing communication becomes possible.
[0044]
In this embodiment, a program configuration and an operation procedure for describing a basic function of the present invention are described, but the configuration and the operation procedure are not limited thereto.
[0045]
Specifically, a function detection operation is performed after transmitting an inquiry signal of the wireless communication device 101 and detecting the device. Even if this operation is performed as a series of search operations, the same effect as described above is obtained. be able to.
[0046]
In addition, after the end of a series of search operations, the registered address and the search address are collated in another step. However, the present invention is not limited to this. For example, unique address information obtained by an inquiry operation is sequentially registered at the time of detection. If a matching address is detected and the matching address is detected, the transmission of the inquiry signal may be interrupted and the operation may be shifted to the function detection operation. In this way, the link can be established more quickly. Can be done.
[0047]
Further, in the present embodiment, the control program for performing control up to link establishment and the communication program for controlling the wireless interface are separated, but the communication program may include the function of the control program.
[0048]
Then, as described in the description of the registration operation, a display operation screen such as the communication program execution screen 206 in FIG. 3 is displayed at the time of starting the program, and is detected when a connection request with the wireless communication device 101 is made. It is also possible to provide a means for displaying the communication function and a function selecting means so as to perform a link connection operation by the selected function.
[0049]
In the above embodiment, after a registered wireless communication device of the same type is detected, a communication function detection operation is performed, the consistency with the registered communication function is confirmed, and when the wireless function is registered, the physical link of the physical link is detected. Although it is described that the operation will shift to the establishment operation, if the communication function at the time of registration of the wireless communication device has not been changed, it is possible to omit this confirmation operation. The time until the link establishment operation can be reduced.
[0050]
In addition, communication is not possible due to a change in the communication function of the partner wireless communication device when communication is performed without confirming the communication function before establishing the link, or malfunction of some functions when performing the function check procedure Confirmation of communication function caused by communication error If communication failure occurs due to occurrence of error, by providing means for notifying communication function mismatch and re-registration means, the user can easily recognize the cause when error occurs This makes it possible to easily change the settings.
[0051]
[Second embodiment]
The first embodiment is a program for storing the name, function, and unique address information of a device having a wireless interface in a device having a wireless interface mounted on a PC as a registration file and performing a wireless communication control. Read the information and establish a wireless link.
[0052]
The second embodiment of the present invention particularly relates to a method of registering a device. From a method of storing identification information of a device to be registered as an information file, a control program corresponding to a function of a registered device is configured and incorporated in the program. Things.
[0053]
Next, a description will be given of a second embodiment in which registration information is incorporated in a control program for a device having a function of performing printing.
[0054]
FIG. 5 is a flowchart showing the operation of the control program according to the second embodiment of the present invention.
[0055]
This control program is intended for a device having a function of performing printing as a registered wireless communication device, and an activation operation of an application for expanding data to be printed and an activation operation of a print control program for performing printing are: It is included in the control program.
[0056]
The second embodiment differs from the first embodiment only in the function of the control program. Therefore, the system configuration diagram and the display screen of the PC will be described with reference to the drawings in the first embodiment.
[0057]
Also, since the device registration operation is performed in the same procedure as in the first embodiment, only the differences from the first embodiment will be described in the description of the operation.
[0058]
Next, a specific operation of the PC 101 according to the second embodiment will be described.
[0059]
First, when a registration operation according to a device registration setting program is performed according to a procedure similar to the procedure in the first embodiment, a device having a printing function (hereinafter, for convenience, is used in the device registration process of step S107 shown in FIG. 2). Although described as a wireless printer, this device is not limited to a printer, but also includes a device that prints together with other functions such as a facsimile. In the case, for a control program that controls communication using printing as a communication function, a device name / communication function and unique address information are registered, and a new control program having the same name as the device name is generated, Will be saved.
[0060]
In a subsequent step, a control program body or a shortcut file of the control program is generated and stored on a basic display screen (hereinafter, referred to as a “desktop screen”).
[0061]
Next, an actual communication control operation in the second embodiment will be described.
[0062]
The communication control program is activated by the user dragging and dropping a data file to be printed onto the shortcut 202 of the wireless printer arranged on the desktop screen by the registration operation.
[0063]
The control program given this data file performs the following operation. That is, the process proceeds to step S220 shown in FIG. 5, and starts a communication program for controlling the wireless interface. In step S221, an inquiry signal transmission instruction for the communication program is transmitted, and the same procedure as in the first embodiment is performed. In steps S222, S223, S224, and S225, a search is made for a wireless communication device existing in the communication area 102 of the wireless communication device 101, and the process proceeds to step S226.
[0064]
In step S226, the unique address information of the device detected by sending the inquiry signal is compared with the unique address information registered in the control program, and in step S227, it is determined whether the registered addresses match. If the detected device does not match the registration information, the process proceeds to step S228, an error is displayed, and the operation of the control program ends.
[0065]
If it is determined that the wireless communication device having the matching address has been detected, the process proceeds to step S229 to acquire the name of the device having the registered unique address information and the communication function, and to register the wireless communication device in the registration information. It is determined in step S230 whether or not the information of the function that is present matches the information of the acquired communication function. Here, if the registered communication functions do not match, the process proceeds to step S231, error information is displayed, and the operation of the communication control program is interrupted.
[0066]
If the registered function matches the detected function, the process proceeds to step S232, where an application capable of expanding the given data file is started, and the file is opened by the application. Thereafter, the print control program is started from the application in step S233, and the process proceeds to steps S234 and S235 to wait for a print instruction or a print cancel instruction.
[0067]
The activation of the application and the activation of the print control program may be performed by developing and using a program for performing new application control. May be controlled by using an application interface command published in.
[0068]
When a print instruction is issued in step S234, the process proceeds to step S236, and a wireless link is established. When the establishment of the link is completed, the process proceeds to step S237 to perform a print processing operation.
[0069]
In the print processing operation, after the print control program converts the data into a data format that can be printed by the wireless printer, the print data is sent to the wireless printer, and when it is confirmed that the transfer of the necessary data related to printing is completed, Disconnecting the wireless link and terminating the application are performed.
[0070]
The printing method according to the second embodiment is an example, and it is possible to cope with different transfer data and communication functions by changing the configuration of the communication control program according to the function of the printer.
[0071]
As a specific example, if the printer has a function of expanding a data file and converting it to print data as a printer function, the data to be transferred is not a print data but a data file. I do. In this case, the communication control program can omit the operation of starting the application and the operation of starting the print control program, and can have a configuration having only the functions necessary for file transfer.
[0072]
Further, in the second embodiment, the function of the communication control program for incorporating the registration information is specialized for the wireless printer. However, the function of this program is not limited to this. In some cases, the communication control program is provided with a function to make a dial-up connection, and the shortcut of the application for browsing the Internet is dragged and dropped on the communication control program, so that the Internet provider's Internet connection can be established via the wireless interface. The access point can be accessed.
[0073]

In the third embodiment, the application screen 403 on the PC 301 is, for example, an application (hereinafter, referred to as a word application) for editing a document.
[0084]
Next, a specific operation of the PC 301 will be described.
[0085]
First, the registration setting operation in the case where a specific wireless printer is registered as a normally used printer in the printer registration program shown in FIG. 7 will be described.
[0086]
In steps S300 and S301, the user installs a printer driver by a procedure similar to a printer installation operation according to a known technique in order to newly install a wireless printer (for example, 303). When the installation of the printer driver is completed, the process proceeds to step S302, and waits for determination whether to set the installed printer as a default printer, and temporarily selects registration as a default printer. Then, the process proceeds to step S303 to determine whether the registered printer is a wireless printer. If the printer installed at this time is a printer connected by wire, the process proceeds to step S305, where the printer is registered by the same operation as that of the known prior art, and the program is terminated.
[0087]
On the other hand, if it is determined that the installed printer is a wireless printer, the process proceeds to step S304, and an inquiry for searching for a wireless communication device in the communication area is performed by the same procedure as that in the first embodiment. A signal transmission instruction is transmitted to the communication program, and in steps S306, S307, and S308, the device detection operation and the display operation of the detected device are performed until a specified time has elapsed.
[0088]
When the specified detection time has elapsed, the process proceeds to step S309, and waits for the user to select a desired wireless printer or a manual information input unit based on the detection result.
[0089]
Here, if the information of the wireless printer desired by the user does not exist in the detection result, the user selects the manual registration instruction. When the manual registration instruction is issued, the registration program proceeds to step S311 to display a screen for manually inputting registration information, wait for information input by the user, and after the input is completed, the registration instruction is selected. Then, the process shifts to step S312 to perform an information registration operation.
[0090]
When the information of the wireless printer desired by the user exists in the detection result, the user selects the device selection from the search result. When the device selection is selected from the search result, the process proceeds to step S310, and waits for the user to select a desired wireless printer from the detection result. When the printer is selected and a registration instruction is issued, the process proceeds to step S312. As described above, in the wireless printer registration process, the unique address, the printer name, and the communication function of the wireless printer are registered.
[0091]
Here, in the third embodiment, although there is no description of the procedure for acquiring communication function information by searching for communication functions, it is assumed that the communication function information is included in the installed printer driver and that there is only a single communication function. The registration is performed using the communication function information included in the driver.
[0092]
However, this registration method is not limited to this, and when the driver does not include the communication function information, the communication function information may be obtained by searching for the communication function using the wireless interface. In the case where a plurality of communication functions related to printing exist in the wireless interface and the functions are registered, either a method of registering only a specific communication function or a method of registering a plurality of functions is adopted. You may do so.
[0093]
The plurality of communication functions include, for example, a communication function for expanding and transferring data such as text on the PC 301 side to print data to be printed by a printer, and a driver for expanding a data file to print data in the printer. Communication function to transfer the data file as it is, transfer only the data storage destination and printing conditions (for example, homepage) to be printed to the printer, and the printer reads the data from the specified storage destination And a communication function for transferring data storage destination information when printing is performed.
[0094]
In the third embodiment, the printer setting program is started not only when the driver is installed but also when the setting of the wireless printer in which the driver is already installed is changed to the default printer. By canceling only the installation of the driver, the wireless printer can be registered.
[0095]
Further, when the setting of the printer is changed, it is determined whether or not the printer that changes the setting is a wireless printer, and only the operation of registering the printer setting program may be executed only when the setting of the wireless printer is changed. .
[0096]
Next, an operation of establishing a wireless link with the wireless printer that has performed the registration setting will be described.
[0097]
First, when a print instruction operation is performed from the screen of the word application 403 in the wireless communication device 301 in which the wireless printer 303 is registered as a printer to be used as a normal use, the print control program is executed in the same manner as in the related art. Upon activation, a print setting dialog box 402 is displayed on the screen, and the control program according to the third embodiment is also activated.
[0098]
When the control program is started, the process first proceeds to step S401, and a communication program for controlling the wireless interface is started. When the start of the program is completed, the process proceeds to step S402, where the communication program exists in the communication area. An instruction to send an inquiry signal to search for the wireless communication device 301 is sent to the communication program, and the process proceeds to step S403.
[0099]
The communication program that has received the inquiry signal transmission instruction sends an inquiry signal for searching for the same type of wireless communication device existing in the communication area 302 of the wireless communication device 301 to the area, and outputs a detection response signal. Is received, a detection result is returned to the control program, and the transmission operation of the inquiry signal is continued until a preset detection time elapses.
[0100]
The control program that has proceeded to step S403, proceeds to step S404, determines whether or not there is a detection response signal from the communication program, and upon receiving this device detection response signal from the communication program, once proceeds to step S405, After saving the detection terminal information, it is determined in step S406 whether or not the device detection time in the communication area has elapsed. If the time has not elapsed, the process returns to step S403 to register a new detection result. repeat.
[0101]
If it is determined that the device detection time has elapsed, the process proceeds to step S407, where the detection result is compared with the unique address of the wireless printer 303 registered as a normal printer, and then the printer that matches in step S408 is determined. It is determined whether or not it has been detected, and if it is determined that they match, the process proceeds to step S414.
[0102]
If it is determined that they do not match, an error display is performed in step S409, and then, in step S410, an instruction as to whether or not to perform the detection operation again is on standby. Here, when a re-detection instruction is issued from the user, the process proceeds to step S402, and the re-search operation of the wireless communication device is performed again.
[0103]
If the user determines not to perform re-detection, the process proceeds to step S411 to wait for determination as to whether or not to select a wireless printer. If not, the control program ends. If it is determined that the selection is to be made, the process proceeds to step S412, where the unique address of the detected wireless printer (for example, 304, 305, 306) is displayed, and the process proceeds to step S413 to wait for a selection operation instruction. Here, when a wireless printer selection operation is performed by the user, the control program proceeds to step S414.
[0104]
The control program that has proceeded to step S414 sends an instruction for detecting the device name and the communication function of the device to the wireless printer having the registered unique address or the newly selected unique address. Get information. When this information is obtained, the process proceeds to step S415, where it is determined whether the registered communication function matches the detected function. If not, an error display is performed in step S416, If they match, a wireless link establishment operation S417 is performed.
[0105]
The control program that has shifted to the connection operation performs the wireless link establishment confirmation operation until the specified time elapses in steps S418 and S419, and when the wireless link is established before the time elapses, shifts to step S420. Perform print processing operation.
[0106]
In this print processing operation, data conforming to the registered communication function is sent to the wireless printer, and the wireless link is disconnected when it is confirmed that the transfer of data necessary for printing has been completed. The end timing differs depending on the communication function to be used and the wireless printer to be mounted. In the third embodiment, the end timing is described as the data transfer completion timing. The end determination timing is not limited to this, and any timing can be used as the end determination timing as long as printing can be completed correctly even when the wireless link is disconnected.
[0107]
When the print processing operation is completed, the control program ends, and the activation is not performed until a new print instruction operation is performed.
[0108]
The third embodiment relates to a program configuration and an operation procedure for explaining a basic function when a wireless printer is registered as a printer to be used normally and a print instruction is issued from an application.
[0109]
The configuration and operation procedure are not limited to the above description. Specifically, in the program configuration, in the third embodiment, a control program for performing control up to link establishment and a control program for controlling the radio interface are provided. Although the communication program is separated and described, a configuration in which the functions of the communication program and the control program are integrated is also possible. A selecting step may be added between steps S414 and S415, and means for selecting a communication function to be used from the print setting dialog box may be provided.
[0110]
With this configuration, it is possible to select an optimum printing unit according to at least one of the application and the print target data. As a specific example, when printing text data having a relatively small amount of data, use a communication function for transferring data expanded into a printable data format. For relatively large data such as JPEG, use a data file. By selecting the communication function for transferring the print data, an optimal print instruction is obtained according to the print content using the same wireless printer.
[0111]
According to the above embodiment, identification information of a desired wireless communication device is registered in advance, and a wireless link establishment operation is performed using the registration information. Therefore, a plurality of wireless communication devices that frequently communicate can be easily registered. Furthermore, complicated operations for selecting a device when a link is established can be eliminated, and communication can be easily performed.
[0112]
Further, according to the above embodiment, since the program for performing the wireless communication control and the registration information are arranged on the basic display screen, the device selection and the activation of the communication control program can be performed more easily, and the user can Also, at the time of communication with a wireless communication device, the same operability as at the time of communication with a device connected by wire can be obtained without being particularly conscious.
[0113]
Further, according to the above-described embodiment, since a complicated operation can be omitted, a link can be quickly established when a user requests establishment of a wireless link.
[0114]
Moreover, according to the above-described embodiment, the name of the registration information file of the device can be changed to an arbitrary name by the user separately from the unique name registered in the device, and the name can be changed by an individual such as a common property. Even when the device name cannot be changed, a device name that can be easily identified by the user can be given, and the convenience is improved.
[0115]
According to the above-described embodiment, since the wireless link can be easily established, it is expected that the user can frequently perform the establishment control of the wireless link, and valuable radio wave resources are effectively used.
[0116]
Further, by applying the above-described embodiment to the registration of a printer, even when the same type of wireless printer exists in the wireless communication area, the user can select a desired printer without being particularly conscious. The same operability as when a conventional printer is set as a printer to be used can be obtained for a wireless printer.
[0117]
Moreover, according to the above embodiment, since control is performed such that a wireless link is established only during printing, unnecessary communication can be omitted, a remarkable effect of effective use of radio wave resources can be obtained, and a similar reason can be obtained. Thus, power consumed during unnecessary communication can be saved.
