Hereinafter, the present embodiment will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a diagram illustrating the information processing apparatus according to the first embodiment. The information processing apparatus 1 includes a display device 1a, a screen information processing unit 1b, a first storage unit 1c, a second storage unit 1d, a determination unit 1e, a control unit 1f, and a device 1g.

The display device 1a displays the screen generated by the screen information processing means 1b.
The screen information processing unit 1b generates a screen to be displayed on the display device 1a based on the screen information. The screen generated by the screen information processing unit 1b is a GUI (Graphical User Interface) for receiving a predetermined operation input. The screen information is data in a format that can describe a GUI. As the format of the screen information, for example, HTML (HyperText Markup Language), XML (Extensible Markup Language), or the like can be considered. The screen information may include a plurality of files. For example, one or more HTML files and one or more script files may be included. The script file is a file that describes a process according to an operation input for an element described in the HTML file. The script file may be a file described in, for example, JavaScript (registered trademark).

  The screen information processing means 1b can acquire screen information from, for example, a server device (not shown) connected to the information processing device 1 via a network. The screen information processing unit 1b registers the control information 2 including the predetermined character string 2a included in the screen information in the first storage unit 1c in response to an operation input on the screen. In the screen information, for example, a character string registered in the first storage unit 1c is defined for each content of operation input to be accepted.

The first storage unit 1c stores control information 2 including a predetermined character string. For example, the control information 2 includes a character string 2a “abcde”.
The second storage unit 1d stores definition information 3 indicating a correspondence relationship between one or more programs for controlling the device 1g and one or more character strings. For example, the definition information 3 includes a character string 3a (“abcde”) and a program 3b (/program/device1g.dat). For example, the character string 3a and the program 3b are associated with each other by “=” (equal) symbols.

  The first storage unit 1c and the second storage unit 1d may be implemented by a disk device such as a solid state drive (SSD) and a hard disk drive (HDD). The first storage unit 1c and the second storage unit 1d may be implemented by different storage areas on the same disk device.

  When the screen information processing unit 1b detects that the control information 2 is registered in the first storage unit 1c, the determination unit 1e detects any one of the definition information 3 stored in the second storage unit 1d. It is determined whether the character string is included in the control information 2. The control information 2 includes a character string 2a “abcde”. At this time, the character string 2a matches the character string 3a. Therefore, in this case, the determination unit 1 e determines that the control information 2 includes the character string 3 a indicated by the definition information 3.

  When it is determined that one of the character strings indicated by the definition information 3 is included, the control unit 1f refers to the definition information 3 and calls a program associated with the determined character string. Control the device. For example, when it is determined that the character string 3a is included in the control information 2, the control unit 1f refers to the definition information 3 and calls the program 3b associated with the character string 3a to control the device. To do. The program 3b is a program for controlling the device 1g.

  The device 1g is a device for realizing a predetermined function. For example, an imaging apparatus for capturing a still image or a moving image or a communication apparatus for realizing wired / wireless communication. Alternatively, a device external to the information processing apparatus 1 that can communicate with the communication apparatus may be used. In this case, the control unit 1f controls an external device via the communication device by the called program.

  The screen information processing unit 1b may be realized by a browser for browsing a web page, for example. Further, the determination unit 1e and the control unit 1f may be included in the browser.

  The information processing apparatus 1 may include a processor such as a CPU (Central Processing Unit) and a memory such as a RAM (Random Access Memory), and may be a computer that executes a program stored in the memory. Good.

  According to the information processing apparatus 1, the determination means 1e detects that the screen information processing means 1b has registered in the first storage means 1c the control information 2 corresponding to the operation input for the screen displayed on the display device 1a. The The determination unit 1e determines whether any character string indicated in the definition information 3 stored in the second storage unit is included in the control information 2. When it is determined that any of the character strings indicated by the definition information 3 is included, the control means 1f refers to the definition information 3 and calls the program 3b associated with the determined character string 3a. Thus, the device 1g is controlled.

  This makes it easy to specify the device to be used. Specifically, the screen information processing means 1b can designate a device to be operated by the information processing apparatus 1 by a character string included in the control information 2 registered in the first storage means 1c. For example, the screen information processing means 1b can use a browser function. The browser is software that can be generally used in the information processing apparatus 1. For this reason, for example, when it is desired to add or change the designation of a device to be controlled on the server device side, it can be handled by changing a character string included in the control information 2. Therefore, device designation can be easily set in the server apparatus or the information processing apparatus 1 without changing an application program (hereinafter simply referred to as an application).

[Second Embodiment]
FIG. 2 illustrates an information processing system according to the second embodiment. The information processing system according to the second embodiment supports maintenance work for information devices (for example, computers and peripheral devices). In this information processing system, maintenance content acquired by a client device (hereinafter simply referred to as a client) is centrally managed by a server device (hereinafter simply referred to as a server). The information processing system includes a client device (hereinafter simply referred to as a client) 100 and a server device (hereinafter simply referred to as a server) 200. The client 100 and the server 200 are connected via the network 10 and the base station 11. The client 100 and the base station 11 are connected wirelessly and communicate using a predetermined frequency band used in mobile communication. The client 100 may be one that can perform wireless LAN connection using Wi-Fi (Wireless-Fidelity, registered trademark). In that case, the client 100 may access the server 200 via an access point (not shown) directly or indirectly connected to the network 10.

  The client 100 is a portable terminal device possessed by maintenance personnel who perform maintenance work. The client 100 includes an imaging unit that captures a still image or a moving image. The maintenance staff can capture a still image or a moving image of the information device to be maintained by the imaging unit.

  The client 100 can be connected to the barcode reader 12 by short-range wireless communication. Examples of near field communication include IrDA (Infrared Data Association) communication, Bluetooth (registered trademark), Wi-Fi, and Zigbee (registered trademark). Hereinafter, Bluetooth will be described as an example of short-range wireless communication.

  The barcode reader 12 is a scanner device that reads barcode information attached to an information device to be maintained. The barcode reader 12 can communicate with the client 100 via Bluetooth. The barcode reader 12 can transmit the read barcode information to the client 100.

  The server 200 manages image data and barcode data received from the client 100. The server 200 has a Web server function and provides the client 100 with screen information (HTML file) describing a GUI that supports maintenance work. For example, the server 200 receives an HTTP (HyperText Transfer Protocol) request specifying a URL (Uniform Resource Locator) of a business support screen from the client 100. As a response to the request, the server 200 transmits an HTML file describing a business support GUI to the client 100.

  Here, the client 100 can execute a Web browser. The Web browser analyzes the HTML file received from the server 200 and displays the GUI on the display on the client 100. The maintenance staff can cause the imaging unit of the client 100 or the barcode reader 12 to acquire predetermined information by performing an operation input according to the GUI. Further, the acquired information can be transmitted to the server 200 by the client 100.

  Note that the client 100 communicates with the barcode reader 12 and the base station 11 when acquiring information using the barcode reader 12. At this time, the client 100 uses two types of communication methods, mobile communication and short-range wireless communication. In this case, it may be difficult to use both communication methods at the same time. This is because the simultaneous use causes problems such as a high load on the client 100 and excessive power consumption. Therefore, when using one communication method, the client 100 controls not to perform communication using the other communication method. Specifically, the client 100 normally connects to the base station 11 and waits for a voice call, an e-mail, or the like. On the other hand, when necessary for maintenance work or the like, mobile communication is disconnected and short-range wireless communication by Bluetooth is performed. When the data communication by Bluetooth is completed, the communication by Bluetooth is disconnected and the mobile communication is resumed.

  FIG. 3 is a diagram illustrating a hardware example of the client. The client 100 includes a CPU 101, a ROM (Read Only Memory) 102, a RAM 103, a mobile communication unit 104, antennas 104a and 105a, a short-range wireless communication unit 105, a recording medium reading unit 106, an imaging unit 107, an image signal processing unit 108, and a display. 108a, an input signal processing unit 109, a touch panel 109a, a keypad 109b, an audio signal processing unit 110, a microphone 110a, and a speaker 110b. Each unit is connected to the bus of the client 100.

  The CPU 101 is a processor that controls information processing of the client 100. The CPU 101 reads out at least a part of a program and data stored in the ROM 102, the RAM 103, and the like, expands the program in the RAM 103, and executes the program. The client 100 may be provided with a plurality of processors to execute the program in a distributed manner.

  The ROM 102 stores a predetermined program such as a BIOS (Basic Input / Output System) program executed when the client 100 is activated. The ROM 102 may be a rewritable nonvolatile memory.

  The RAM 103 is a volatile memory that temporarily stores programs executed by the CPU 101 and data used for processing. Note that the client 100 may include a type of memory other than the RAM, or may include a plurality of memories.

  The mobile communication unit 104 performs radio signal processing and realizes radio communication with the base station 11 via the mobile communication network. Specifically, the mobile communication unit 104 demodulates and decodes a signal received from the base station 11 via the antenna 104a, and outputs the obtained reception data to the CPU 101. Further, the mobile communication unit 104 encodes and modulates transmission data acquired from the CPU 101, and transmits the obtained transmission signal to the base station 11 via the antenna 104a.

  The short-range wireless communication unit 105 performs wireless signal processing and realizes wireless communication with the barcode reader 12 by Bluetooth. Specifically, the short-range wireless communication unit 105 encodes and modulates transmission data acquired from the CPU 101, and transmits the obtained transmission signal to the barcode reader 12 via the antenna 105a. Further, the short-range wireless communication unit 105 demodulates and decodes a signal received from the barcode reader 12 via the antenna 105 a and outputs the obtained reception data to the CPU 101.

The recording medium reading unit 106 reads data stored in the recording medium 13 and stores the data in the recording medium 13. For example, a semiconductor memory can be used as the recording medium 13.
The imaging unit 107 captures a still image or a moving image.

  The image signal processing unit 108 outputs an image to the display 108 a in accordance with a command from the CPU 101. For example, a liquid crystal display can be used as the display 108a.

  When the input signal processing unit 109 detects a touch operation on the touch panel 109a or a key press on the keypad 109b, the input signal processing unit 109 acquires an input signal indicating the touch operation or a pressed key and outputs the input signal to the CPU 101.

  The audio signal processing unit 110 acquires an audio analog signal from the microphone 110a, performs predetermined signal conversion processing, and outputs audio data to the CPU 101. The audio signal processing unit 110 acquires audio data from the CPU 101, performs predetermined signal conversion processing, and causes the speaker 110b to reproduce the audio.

  FIG. 4 is a diagram illustrating a software example of the client according to the second embodiment. 4 may be a module of a program executed by the client 100. 4 may be an electronic circuit such as an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit).

The client 100 includes a file I / O (Input / Output) unit 120, a storage unit 130, a Web browser 140, and a device processing unit 150.
The file I / O unit 120 is a storage area that can be read and written by the web browser 140 and the device processing unit 150. As the file I / O unit 120, for example, a local storage (Local Storage), standardized in HTML5, an arbitrary file in the WebSQLDataBase, a local directory, or the like can be considered. In the following, local storage is assumed.

The storage unit 130 stores a program definition file. The program definition file defines the correspondence between character strings and device control programs.
The web browser 140 displays a screen such as a business menu on the display 108 a based on the HTML file acquired from the server 200. The web browser 140 receives a predetermined operation input using the touch panel 109a and the keypad 109b for the screen. Then, the Web browser 140 registers control information including a predetermined character string corresponding to the operation input in the file I / O unit 120.

  The device processing unit 150 controls devices that can be used by the client 100 based on control information registered in the file I / O unit 120. For example, the mobile communication unit 104, the short-range wireless communication unit 105 (the barcode reader 12 that communicates via the short-range wireless communication unit 105), and the imaging unit 107 are controlled. The device processing unit 150 includes a determination unit 151 and a control unit 152.

  The determination unit 151 monitors the file I / O unit 120. The determination unit 151 detects that control information has been registered in the file I / O unit 120 by the Web browser 140. Then, the determination unit 151 refers to the program definition file stored in the storage unit 130 and determines whether the predetermined character string indicated by the program definition file is included in the control information.

  When the determination unit 151 determines that the character string indicated by the program definition file is included in the control information, the control unit 152 refers to the program definition file and specifies a program corresponding to the character string. The control unit 152 controls the device by calling the specified program.

  In addition, the control unit 152 acquires data from the device. For example, the image data obtained by the image capturing unit 107 from the image capturing unit 107 is acquired. For example, the barcode value read by the barcode reader 12 is acquired from the short-range wireless communication unit 105. The control unit 152 stores data received from the device or information indicating the data in the file I / O unit 120. This is because a process based on data acquired from the device is executed by a predetermined application. For example, the web browser 140 can display data acquired from the device on the display 108a. Further, the web browser 140 can transmit the selected data to the server 200.

  Here, the client 100 according to the second embodiment is an example of the information processing apparatus 1 according to the first embodiment. Moreover, the determination part 151 is an example of the determination means 1e. The control unit 152 is an example of the control unit 1f.

  FIG. 5 is a diagram illustrating an example of the local storage. The local storage 121 is stored in the file I / O unit 120. The local storage 121 is a KVS (Key-Value Store), and stores data in pairs of a key and a value.

  Multiple types of information are registered in the local storage 121 by the Web browser 140 and the control unit 152. The information includes first control information 121a, second control information 121b, and stored data 121c. The first control information 121a and the second control information 121b are registered by the Web browser 140 and used for the processing of the device processing unit 150. The stored data 121c is registered by the control unit 152 and used for processing of the Web browser 140.

  The first control information 121a is registered with instructions related to device control. Specifically, the device control instruction type (execution / stop) (hereinafter, also referred to as instruction type) is registered as the key. A character string for specifying a device control program is registered as a value.

  For example, a pair (Execute, Camera) of (key, value) can be registered in the first control information 121a. “Execute” as a key indicates that the device is instructed to execute the process. The process stop instruction by the device is described by a character string “Stop”. The value “Camera” indicates a character string for specifying a device control program.

  The second control information 121b registers parameters used for device control. Specifically, the character string corresponding to the variable set as the key is registered. Registers the value to be set in the parameter as value.

  For example, a pair (param1, 600x400) of (key, value) can be registered in the second control information 121b. The key “param1” indicates that the value “600 × 400” is set in the parameter of the parameter1 defined in the program definition file.

  Further, for example, a pair (param2, 3) of (key, value) can be registered in the second control information 121b. The key “param2” indicates that the value “3” of the value is set in the parameter of the parameter2 defined in the program definition file.

  The stored data 121c is obtained by registering data (or information indicating the data) acquired by the imaging unit 107 or the barcode reader 12. Specifically, the type of data stored as the key (path, data body, encoding format, etc.) is registered. Information indicating the data acquired as value (path contents, data body and encoded data body) is registered. As the stored data 121c, for example, information as shown in FIGS. 5A, 5B, and 5C can be registered.

  For example, in FIG. 5A, a pair (path,... /Img/common/img001.jpg) of (key, value) can be registered as the stored data 121c. The key “path” indicates that the information stored in the value is a path to the data body acquired by the device. The value “.. ./img/common/img001.jpg” is a path to the data body acquired by the device.

  For example, in FIG. 5B, a pair (data, 328931) of (key, value) can be registered as the stored data 121c. The key “data” indicates that the information stored in the value is the data body acquired by the device. The value “328931” is the data body acquired by the device.

  For example, as shown in FIG. 5C, a pair (base64, LS0tIW5nHJ...) Of (key, value) can be registered as the storage data 121c. The key “base64” indicates that the information stored in the value is obtained by encoding the data body acquired by the device in Base64. The value “LS0tIW5nHJ...” is obtained by encoding the data body acquired by the device with Base64. For example, when the binary data cannot be stored in the value, the control unit 152 may encode binary data such as an image with Base64 and then register the binary data in the local storage 121.

  Note that the same data structure as that of the local storage 121 can be implemented even when an arbitrary file in the WebSQL Database or the local directory is used. When using an arbitrary file in the local directory, for example, a CSV (Comma Separated Values) format file or an XML format file may be used.

  For the local storage 121, WebSQLDataBase, and any file in the local directory defined by HTML5, the presence / absence of the data expiration date and the setting value can be arbitrarily set. It is also possible to keep the data permanently. In addition, with respect to accesses from a plurality of different Web pages and applications, it is possible to arbitrarily set whether or not there is a restriction and a restriction range. Therefore, it can be easily accessed from any application. Here, for example, it is conceivable to use cookie. However, when using cookie, there are restrictions on specifications such as expiration date, access restriction, size and number, and it is difficult to handle. On the other hand, by using the local storage 121 or the like as in the present embodiment, various data can be easily handled by a plurality of applications without being restricted by the cookie.

  FIG. 6 is a diagram illustrating an example of a program definition file. The program definition file 131 is stored in the storage unit 130. The program definition file 131 is definition information that defines a correspondence between a character string and a device control program. The program definition file 131 also defines parameters used when executing the program. The program definition file 131 includes records 131a, 131b, 131c, 131d, 131e, 131f, 131g, 131h, 131i, 131j, and 131k.

  The records 131a, 131e, and 131i indicate the types of records that belong to the lower row than the record. For example, “[Command] [Execute]” is described in the record 131a. This indicates that the records 131b, 131c, and 131d are information that defines a device control program corresponding to the instruction type “Execute” (operation execution).

  Specifically, the record 131b describes “Camera (1) = / program / ExecCamera.dat”. This is a device control program “/program/ExecCamera.dat” associated with the character string “Camera” and is called when the program executes processing by the device. Show. Here, the program indicated by the record 131b is a program for controlling the imaging of a still image by the imaging unit 107. The character string “(1)” added to the character string “Camera” on the left side indicates that the program is to be called at the beginning of a series of processes by the imaging unit 107. For example, “(2)” is added to a character string corresponding to a program to be called next to the program. If it is next, “(3)” is added. When processing is performed by calling a single program, only the record with “(1)” is defined.

  The records 131c and 131d have the same description method as the record 131b. Here, the record 131c indicates a program for controlling the stop of the mobile communication unit 104 and the activation of the short-range wireless communication unit 105. The record 131d indicates a program for controlling reading of a barcode by the barcode reader 12 and transmission of the read code to the client 100. In this way, device execution / stop in a series of data acquisition processes is described in a plurality of programs, and the execution order is described as “(1)”, “(2)”.

  Further, for example, “[Command] [Stop]” is described in the record 131e. This indicates that the record 131f is information defining a device control program corresponding to the instruction type “Stop” (operation stop).

  Specifically, the record 131f describes “Camera (1) = / program / StopCamera.dat”. This is that the device control program “/program/StopCamera.dat” is associated with the character string “Camera” and is called when the program stops the operation of the device. Show. Here, the program indicated by the record 131 f is a program for controlling the operation stop of the imaging unit 107. The meaning of the character string “(1)” added to the character string “Camera” on the left side is the same as that of the record 131b.

  The records 131g and 131h are described in the same manner as the record 131f. Here, the record 131g indicates a program for controlling the stop of the barcode reader 12. The record 131h indicates a program that controls stop of the short-range wireless communication unit 105 and activation of the mobile communication unit 104.

  In addition, for example, “[parameters] [Execute]” is described in the record 131i. This indicates that the records 131j and 131k are information defining parameters to be input to the program when the device control program corresponding to the instruction type “Execute” is executed.

  Specifically, the record 131j describes “Camera (1) = param1 (size), param2 (frequency)”. This defines the parameters to be input to the control string (corresponding to the record 131b) of the instruction type “Execute” for the character string “Camera”. More specifically, the value specified by “param1” is set to the parameter “size” in the program, and the value specified by “param2” is set to the parameter “frequency” in the program. , Indicate. Here, the parameter “size” indicates the size of the image data captured by the imaging unit 107 (width × height pixel count). The parameter “frequency” indicates the number of times of imaging by the imaging unit 107.

  The record 131k has the same description method as the record 131j. Here, the record 131k defines parameters to be input when executing the program indicated by the record 131c. More specifically, the value specified by “param1” should be set to the parameter “mode” in the program, and the value specified by “param2” should be set to the parameter “connect” in the program. Show. Here, the parameter “mode” is information for designating a predetermined mode for connection. The parameter “connect” is information for designating a profile or the like used for Bluetooth connection.

  There are two types of control programs 131c and 131d associated with the character string “BSscan”. On the other hand, in the records 131c and 131k, the character string “(1)” added to “BSscan” on the left side matches. As a result, the records 131c and 131k can be associated with each other.

  Further, when the parameter input is unnecessary, the parameter definition is not described. Further, the number of parameters defined for the control program may be one, or may be two or more.

FIG. 7 is a diagram illustrating an example of a business support screen. FIG. 7A illustrates a business support screen 300. FIG. 7B illustrates a business support screen 300a.
The business support screen 300 is a screen for selecting data to be acquired. The maintenance staff designates the URL of the business support screen 300 on the Web browser 140. Then, the Web browser 140 acquires an HTML file corresponding to the URL from the server 200 and displays the business support screen 300 on the display 108a. On the business support screen 300, an imaging button 310, a barcode reading button 320, and an end button 330 are displayed.

  The imaging button 310 is a button for capturing an image of the maintenance target information device by the imaging unit 107 and acquiring still image data. The barcode reading button 320 is a button for reading a barcode attached to the maintenance target information device by the barcode reader 12 and acquiring a reading result. The end button 330 is a button for closing the work support screen 300 and ending the work. The end button 330 may be used as a button for ending the process executed by each button after the imaging button 310 or the barcode reading button 320 is pressed.

  The business support screen 300a is a screen for browsing / selecting still image data acquired by the imaging unit 107 after the imaging button 310 is pressed. For example, images 311a, 312a, and 313a are displayed in the area 310a of the business support screen 300a. For example, the maintenance staff performs a flick operation (for example, in the left-right direction) on the area 310a. Then, the Web browser 140 scrolls the display in the area 310a (places any image in the center). Further, for example, the maintenance staff taps the images 311a, 312a, and 313a. Then, the Web browser 140 accepts selection of the tapped image and performs processing such as further enlarging the image or transmitting it to the server 200.

  FIG. 8 is a diagram illustrating a description example of the HTML file of the business support screen. In the HTML file 400, descriptions corresponding to the display contents shown on the business support screen 300 are extracted. The HTML file 400 includes descriptions 410 and 420.

  A description 410 describes the imaging button 310. When the imaging button 310 is pressed, the function “ExecCamera ()” defined in the script file “Camera.js” arranged in a predetermined directory is executed.

  A description 420 describes the barcode reading button 320. When the barcode reading button 320 is pressed, the function “ExecBSscan ()” defined in the script file “BSscan.js” arranged in a predetermined directory is executed.

  FIG. 9 is a diagram illustrating a description example of a script. FIG. 9A shows a script file 500 (“Camera.js”). FIG. 9B shows a script file 600 (BSscan.js). The script files 500 and 600 are described in a JavaScript format, for example.

  The script file 500 includes functions “ExecCamera ()”, “StopCamera ()”, and “selectImg ()”. The function “ExecCamera ()” is a function used when performing execution control of the imaging unit 107. The function “StopCamera ()” is a function used when stop control of the imaging unit 107 is performed. The function “selectImg ()” is a function used for displaying the image data acquired by the imaging unit 107 and accepting selection.

  For example, the function “ExecCamera ()” includes codes 510, 520, and 530. Codes 510, 520, and 530 describe processing for registering a (key, value) pair in the local storage 121.

  The code 510 is a process for registering (Execute, Camera). The code 520 is a process for registering (param1, 600 × 400). The code 530 is a process for registering (param2, 3).

  Note that either or both of the codes 520 and 530 may not be included. When no parameter is specified, the control unit 152 controls the imaging unit 107 with default settings.

  For example, the function “StopCamera ()” includes a code 540. The code 540 is a process of registering the (key, value) pair (Stop, Camera) in the local storage 121.

  The script file 600 includes functions “ExecBSscan ()” and “StopBSscan ()”. The function “ExecBscan ()” is a function used when the barcode reader 12 performs barcode reading. The function “StopBscan ()” is a function used when the barcode reading is finished. The function “ExecBSscan ()” includes codes 610, 620, and 630. Codes 610, 620, and 630 describe processing for registering a (key, value) pair in the local storage 121.

  Code 610 is a process for registering (Execute, BSscan). The code 620 is a process for registering (param1, mode01). The code 630 is a process for registering (param2, profile01).

  One or both of the codes 620 and 630 may not be included. When the parameter is not specified, the control unit 152 controls the mobile communication unit 104, the short-range wireless communication unit 105, and the barcode reader 12 using preset default parameters.

  Further, for example, the function “StopBscan ()” includes the code 640. The code 640 is a process for registering a pair (Stop, BSscan) of (key, value) in the local storage 121.

Further, the functions described in the script files 500 and 600 may be described in the HTML file 400.
Next, a processing procedure of the client 100 having the above configuration will be described. In the following description, control of acquiring image data by the imaging unit 107 and uploading it to the server 200 will be exemplified.

  FIG. 10 is a flowchart illustrating a processing example of the client. In the following, the process illustrated in FIG. 10 will be described in order of step number. It is assumed that all data in the local storage 121 is cleared immediately before the process of step S11.

  (Step S <b> 11) The Web browser 140 receives the HTML file 400 from the server 200. The web browser 140 displays the business support screen 300 on the display 108 a based on the HTML file 400.

(Step S <b> 12) The web browser 140 receives a tap operation on the imaging button 310 by a maintenance staff.
(Step S <b> 13) The Web browser 140 registers control information in the local storage 121. Specifically, a pair (Execute, Camera) of (key, value) is registered. Also, (param1,600x400) and (param2,3) are registered.

  (Step S14) The determination unit 151 monitors the local storage 121. The determination unit 151 detects that control information (key, value) = (Execute, Camera) is registered in the local storage 121 in step S13. Then, the program definition file 131 is referred to and it is determined whether the character string corresponding to the control program related to the instruction type “Execute” is included in the value of the key “Execute”. If included, the process proceeds to step S15. If not included, the process ends. Here, the “character string corresponding to the control program” is a character string excluding the numerical values in the “()” symbol and the “()” symbol among the character strings on the left side of the records 131b, 131c, and 131d. Here, the value “Camera” is registered in the local storage 121 for the key “Execute”. At this time, the determination unit 151 determines that the character string “Camera” indicated on the left side of the record 131b of the program definition file 131 is included in the control information.

  (Step S15) The determination unit 151 specifies a control program corresponding to the character string specified by the control information. Specifically, the determination unit 151 identifies “/program/ExecCamera.dat” corresponding to the character string “Camera” on the left side of the record 131b. The determination unit 151 notifies the control unit 152 of the identified program.

  (Step S16) The control unit 152 refers to the program definition file 131 and specifies the character strings “param1” and “param2” for parameter definition corresponding to the program (record 131b) specified in step S15 (in the record 131j). Equivalent). Then, the control unit 152 specifies a character string for parameter definition in the key of the local storage 121, and acquires the value. Thereby, the control unit 152 obtains the setting value “600 × 400” of the parameter “size” and the setting value “3” of the parameter “frequency”. If the character string for parameter definition is not defined in the program definition file 131, or if it is defined but the key corresponding to the local storage 121 is not registered, skip this step. Proceed to step S18.

(Step S <b> 17) The control unit 152 calls the program notified from the determination unit 151 and controls the imaging unit 107. Details will be described later.
(Step S <b> 18) The control unit 152 acquires image data from the imaging unit 107. For example, if the imaging unit 107 has performed imaging three times, the control unit 152 acquires three pieces of image data. The control unit 152 writes image data (for example, file name “img001.jpg”) in a predetermined directory (for example, “.. ./Img/common/”). If there are multiple image data, the file name is changed and multiple image data are written.

  (Step S <b> 19) The control unit 152 registers the image data path in the local storage 121. Specifically, a pair (path,... /Img/common/img001.jpg) of (key, value) is registered. The key “path” indicates that the value is information indicating a path to the image data. If there are a plurality of image data, a plurality of paths are registered.

  (Step S <b> 20) The web browser 140 detects that new information has been registered in the local storage 121. Then, the Web browser 140 registers control information instructing to stop the imaging unit 107 in the local storage 121. When the determination unit 151 detects registration of the control information, the determination unit 151 performs the same processing as steps S14 and S15. The control unit 152 controls the stop of the imaging unit 107 based on the determination result of the determination unit 151. Details will be described later.

  (Step S <b> 21) The Web browser 140 specifies “path” as the key, and acquires path information from the local storage 121. The web browser 140 acquires image data according to the designation of the path. The web browser 140 generates a business support screen 300a for selecting image data based on the acquired image data. The web browser 140 displays the business support screen 300a on the display 108a.

(Step S22) The web browser 140 receives an input of an image selection operation (tap operation) by a maintenance staff. For example, an input of a selection operation for the image 312a is received.
(Step S <b> 23) The web browser 140 uploads image data corresponding to the selected image 312 a to the server 200. The upload process is described in advance in the HTML file 400, for example.

(Step S24) The web browser 140 deletes all data stored in the local storage 121.
Here, in step S19, instead of the path to the image data, the data body or data obtained by encoding the data body into Base64 or the like may be registered in the local storage 121. In this case, a character string such as “data” or “base64” is registered in the key according to the stored data (see FIG. 5). For example, when “base64” is specified as the data format, the Web browser 140 can restore the data body by decoding the data acquired from the local storage 121 with the Base64. In which format the data is stored in the local storage 121 is preset in the control unit 152.

Next, the device execution control procedure in step S17 will be described.
FIG. 11 is a flowchart illustrating a processing example of device execution control. In the following, the process illustrated in FIG. 11 will be described in order of step number.

  (Step S <b> 31) The control unit 152 calls the control program for the imaging unit 107 notified from the determination unit 151. At this time, if there is a parameter acquired in step S16, the parameter is input to the calling program. The program is executed by the CPU 101, and the imaging unit 107 is activated and executed.

  (Step S <b> 32) The imaging unit 107 images the maintenance target information device. The imaging method is specified by the parameter input in step S31, for example. For example, when “600 × 400” is input to “size”, an image is captured with a resolution of 600 pixels wide and 400 pixels high. For example, when “3” is input to “frequency”, the image is captured three times at predetermined time intervals.

(Step S <b> 33) The imaging unit 107 outputs the captured image data to the control unit 152. For example, if the image is taken three times, three pieces of image data are output.
In this way, the client 100 registers control information corresponding to the operation on the business support screen 300 in the local storage 121. The client 100 calls a device control program corresponding to the control information in the local storage 121 to control the device.

Next, the procedure of device stop control in step S20 will be described.
FIG. 12 is a flowchart illustrating a processing example of device stop control. In the following, the process illustrated in FIG. 12 will be described in order of step number.

  (Step S <b> 41) Upon detecting that the image data path is registered in the local storage 121, the Web browser 140 registers control information for stopping the imaging unit 107 in the local storage 121. Specifically, a (key, value) pair (Stop, Camera) is registered.

  (Step S42) The determination unit 151 detects that control information (key, value) = (Stop, Camera) is registered in the local storage 121 in step S41. Then, the program definition file 131 is referenced to detect that the character string “Camera” corresponding to the control program related to the instruction type “Stop” is included as a value for the key “Stop” in the local storage 121.

  (Step S43) The determination unit 151 specifies a control program of the instruction type “Stop” corresponding to the character string specified by the control information. Specifically, the determination unit 151 specifies “/program/StopCamera.dat” corresponding to the character string “Camera” on the left side of the record 131f. The determination unit 151 notifies the control unit 152 of the identified program.

  (Step S <b> 44) The control unit 152 calls the control program for the imaging unit 107 notified from the determination unit 151. In this example, it is assumed that no parameters are registered in the local storage 121 in step S41. On the other hand, even when stop control is performed, parameters may be specified as in the case of execution control.

(Step S45) The program called by the control unit 152 is executed by the CPU 101, and the imaging unit 107 is stopped.
In this way, the client 100 detects that data has been acquired by the device, and registers control information for stopping the device in the local storage 121.

  Note that the device stop control process may be executed at another timing, for example, immediately after the upload of the image data is completed. For example, in FIG. 10, step S20 may be executed immediately after the processing of any one of steps S21 to S23 is completed. For example, step S20 may be performed in parallel with steps S21 to S23.

Next, the relationship between the components when controlling the imaging unit 107 will be specifically described.
FIG. 13 is a sequence diagram illustrating an example of control of the imaging unit. In the following, the process illustrated in FIG. 13 will be described in order of step number.

  (Step ST101) The determination unit 151 regularly monitors the local storage 121. The determination unit 151 checks for an update of the local storage 121. At this stage, no information is registered in the local storage 121. For this reason, the determination unit 151 does not detect an update.

  (Step ST102) In response to the request from the Web browser 140, the server 200 transmits the HTML file 400 of the business support screen 300. The web browser 140 receives the HTML file 400 from the server 200.

  (Step ST103) The Web browser 140 displays the business support screen 300 on the display 108a. The web browser 140 accepts a tap operation on the imaging button 310. The Web browser 140 registers control information (key, value) = (Execute, Camera) and the like in the local storage 121. Then, the Web browser 140 starts monitoring the update of the local storage 121 at a predetermined cycle.

(Step ST104) The determination unit 151 checks for an update of the local storage 121. The determination unit 151 detects that the local storage 121 has been updated.
(Step ST105) The determination unit 151 acquires the control information registered by the Web browser 140 from the local storage 121 in Step ST103.

  (Step ST106) The determination unit 151 determines that the character string “Camera” (related to the instruction type “Execute”) included in the program definition file 131 is included in the value corresponding to the key “Execute” of the control information. Then, the determination unit 151 refers to the program definition file 131 and notifies the control unit 152 of a control program (corresponding to the record 131b) corresponding to the character string “Camera”.

  (Step ST107) The Web browser 140 checks for an update of the local storage 121. At the stage of this step, the local storage 121 has not been updated. For this reason, the Web browser 140 does not detect an update.

  (Step ST108) The control part 152 calls the control program notified from the determination part 151, and controls the imaging of the information equipment by the imaging part 107. When a parameter is designated as the control information, the parameter is input to the control program to control the imaging unit 107.

(Step ST109) The control unit 152 acquires the image data generated by the imaging unit 107.
(Step ST110) The control unit 152 stores the image data generated by the imaging unit 107 in a predetermined directory. The control unit 152 registers the path of the image data in the local storage 121. For example, (key, value) = (path,... /Img/common/img001.jpg).

  (Step ST111) The Web browser 140 checks for an update of the local storage 121. The web browser 140 detects that the local storage 121 has been updated. The web browser 140 stops monitoring.

  (Step ST112) The Web browser 140 registers the control information (key, value) = (Stop, Camera) in the local storage 121. Then, stop control of the imaging unit 107 is started by the determination unit 151 and the control unit 152 (described later).

(Step ST113) The web browser 140 acquires the path of the newly registered image data from the local storage 121.
(Step ST114) The web browser 140 acquires image data from the path and transmits it to the server 200. The server 200 receives the image data and stores it in a predetermined storage unit.

(Step ST115) The Web browser 140 deletes data (control information and acquired data) stored in the local storage 121.
Next, stop control of the imaging unit 107 derived from step ST112 will be described.

FIG. 14 is a sequence diagram (continued) illustrating an example of control of the imaging unit. In the following, the process illustrated in FIG. 14 will be described in order of step number.
(Step ST121) The determination unit 151 checks the update of the local storage 121. The determination unit 151 detects that the local storage 121 has been updated. This step is executed before step ST114.

(Step ST122) The determination unit 151 acquires the control information registered by the Web browser 140 in Step ST112 from the local storage 121.
(Step ST123) The determination unit 151 determines that the character string “Camera” (related to the instruction type “Stop”) included in the program definition file 131 is included in the value corresponding to the key “Stop” of the control information. Then, the determination unit 151 refers to the program definition file 131 and notifies the control unit 152 of a control program (corresponding to the record 131f) corresponding to the character string “Camera”.

(Step ST124) The control part 152 calls the control program notified from the determination part 151, and stops the imaging part 107. FIG.
In this way, the client 100 performs a series of controls of the imaging unit 107.

Next, an example of processing for controlling the mobile communication unit 104, the short-range wireless communication unit 105, and the barcode reader 12 to read the barcode attached to the information device will be described.
FIG. 15 is a sequence diagram illustrating a control example of barcode reading. In the following, the process illustrated in FIG. 15 will be described in order of step number.

  (Step ST131) The determination unit 151 periodically monitors the local storage 121. The determination unit 151 checks for an update of the local storage 121. At this stage, no information is registered in the local storage 121. For this reason, the determination unit 151 does not detect an update.

  (Step ST132) In response to the request from the Web browser 140, the server 200 transmits the HTML file 400 of the business support screen 300. The web browser 140 receives the HTML file 400 from the server 200.

  (Step ST133) The web browser 140 displays the business support screen 300 on the display 108a. Web browser 140 accepts a tap operation on barcode reading button 320. The Web browser 140 registers control information (key, value) = (Execute, BScan) or the like in the local storage 121. Then, the Web browser 140 starts monitoring the update of the local storage 121 at a predetermined cycle.

(Step ST134) The determination unit 151 checks the update of the local storage 121. The determination unit 151 detects that the local storage 121 has been updated.
(Step ST135) The determination unit 151 acquires the control information registered by the Web browser 140 from the local storage 121 in Step ST133.

  (Step ST136) The determination unit 151 determines that the character string “BSscan” (related to the instruction type “Execute”) included in the program definition file 131 is included in the value corresponding to the key “Execute” of the control information. Then, the determination unit 151 refers to the program definition file 131 and controls the control program corresponding to the character string “BSscan” (corresponding to the records 131c and 131d) according to the order defined by “()”. 152 is notified.

  (Step ST137) The Web browser 140 checks for an update of the local storage 121. At the stage of this step, the local storage 121 has not been updated. For this reason, the Web browser 140 does not detect an update.

  (Step ST138) The control unit 152 calls the first control program (/program/ExecBT.dat) notified from the determination unit 151, and stops the mobile communication unit 104.

(Step ST139) The control unit 152 further activates the short-range wireless communication unit 105 by the program to establish communication with the barcode reader 12.
(Step ST140) The control unit 152 calls the next control program (/program/ExecBR.dat) notified from the determination unit 151, and reads the barcode of the barcode reader 12 via the short-range wireless communication unit 105. Control. If a parameter is specified as control information in steps ST138 to ST140, the parameter is input to the corresponding control program to control each device.

(Step ST141) The control unit 152 acquires code data (for example, “328931”) read by the barcode reader 12 via the short-range wireless communication unit 105.
(Step ST142) The control unit 152 registers the acquired read data in the local storage 121. For example, (key, value) = (data, 328931).

  (Step ST144) The Web browser 140 registers the control information (key, value) = (Stop, BSscan) in the local storage 121. Then, stop control of the barcode reader 12 is started by the determination unit 151 and the control unit 152 (described later).

  (Step ST145) The Web browser 140 acquires newly registered read data from the local storage 121. At this time, since “data” is specified in the key of the read data, the Web browser 140 can recognize the read data as the data body.

(Step ST146) The Web browser 140 transmits the acquired read data to the server 200. The server 200 receives the read data and stores it in a predetermined storage unit.
(Step ST147) The web browser 140 deletes data (control information and acquired data) stored in the local storage 121.

Next, stop control of the barcode reading process derived from step ST144 will be described.
FIG. 16 is a sequence diagram (continued) showing an example of bar code reading control. In the following, the process illustrated in FIG. 16 will be described in order of step number.

  (Step ST151) The determination unit 151 checks for an update of the local storage 121. The determination unit 151 detects that the local storage 121 has been updated. This step is executed before step ST147.

(Step ST152) The determination unit 151 acquires the control information registered by the Web browser 140 in Step ST144 from the local storage 121.
(Step ST153) The determination unit 151 determines that the character string “BSscan” (related to the instruction type “Stop”) included in the program definition file 131 is included in the value corresponding to the key “Stop” of the control information. Then, the determination unit 151 refers to the program definition file 131 and controls the control program (corresponding to the records 131g and 131h) corresponding to the character string “BSscan” according to the order defined by “()”. 152 is notified.

  (Step ST154) The control unit 152 calls the first control program (/program/StopBR.dat) notified from the determination unit 151, and disconnects the communication between the short-range wireless communication unit 105 and the barcode reader 12. .

  (Step ST155) The control unit 152 calls the next control program (/program/StopBT.dat) notified from the determination unit 151, and stops the short-range wireless communication unit 105.

(Step ST156) The control unit 152 further activates the mobile communication unit 104 by the program.
In this way, the client 100 controls barcode reading.

  As described above, the server 200 can designate a device desired to be used by the client 100 by the description of the HTML file 400. The HTML file 400 can be analyzed by the Web browser 140. The web browser 140 is software that can be generally used by the client 100. For this reason, for example, when it is desired to add / change the designation of a device in the server 200, it can be dealt with by changing the setting value of the control information (key-value pair) or the function in the script. Therefore, setting of device designation can be easily performed without changing the application or the like in the client 100 or the server 200. Furthermore, the client 100 can execute a series of processes by a plurality of devices by calling programs in the order defined in the program definition file 131. Thereby, it is possible to easily specify control using a plurality of devices from the server 200.

  It is also possible to specify parameters to be input to the program to be called. Specifically, a character string “param” indicating a parameter is registered in the local storage 121 as a key. The control unit 152 refers to the key and the program definition file 131 and determines to which program the registered parameter is to be input. In this way, in addition to device designation, parameters for controlling the device can be easily designated.

  In addition, the control unit 152 stores information regarding data acquired by the device in the local storage 121. Thereby, processing using the data by another application can be easily realized.

  At that time, the control unit 152 sets the data to be stored to value and the data format to key. Thereby, the application can easily identify the data format of the data. For example, if “path” is registered in the key, it can be identified as a data path. For example, if “data” is registered in the key, it can be identified as the data body. For example, if “base64” is registered in the key, it can be identified as data encoded in Base64. Other data formats other than these may be registered. Specifically, it is also conceivable to register data attributes (for example, information indicating that the data is equipment code), handling methods (for server transmission and server non-transmission), and the like.

[Third Embodiment]
Next, a third embodiment will be described. Differences from the second embodiment will be mainly described, and description of similar matters will be omitted.

  In the second embodiment, the example in which the function of the device processing unit 150 is implemented by an application separate from the Web browser has been described. On the other hand, the function of the device processing unit 150 may be provided in the Web browser. Therefore, in the third embodiment, a case where the function of the device processing unit 150 is provided in a Web browser is illustrated.

  Here, the overall configuration of the information processing system of the third embodiment is the same as the overall configuration of the information processing system of the second embodiment described in FIG. The hardware example of the client according to the third embodiment is the same as the hardware example of the client 100 according to the second embodiment described with reference to FIG. Note that the client of the third embodiment is referred to as a client 100a in order to distinguish it from the client 100 of the second embodiment.

  FIG. 17 is a diagram illustrating a software example of the client according to the third embodiment. 17 may be a module of a program executed by the client 100a. Also, some or all of the units shown in FIG. 4 may be electronic circuits such as FPGA and ASIC.

The client 100a includes a file I / O unit 120, a storage unit 130, and a web browser 140a.
The file I / O unit 120 and the storage unit 130 are the same as those in the second embodiment described with the same reference numerals and names in FIG.

The web browser 140 a includes an HTML processing unit 141, a determination unit 142, and a control unit 143.
The HTML processing unit 141 displays a screen such as a business menu on the display 108 a based on the HTML file acquired from the server 200. The HTML processing unit 141 receives a predetermined operation input using the touch panel 109a and the keypad 109b for the screen. Then, the HTML processing unit 141 registers control information including a predetermined character string corresponding to the operation input in the file I / O unit 120. That is, the HTML processing unit 141 has the main function of the Web browser 140 according to the second embodiment described with reference to FIG.

  The determination unit 142 monitors the file I / O unit 120. The determination unit 142 detects that control information has been registered in the file I / O unit 120 by the HTML processing unit 141. Then, the determination unit 142 refers to the program definition file stored in the storage unit 130 and determines whether the character string indicated by the program definition file is included in the control information.

  When the determination unit 142 determines that the character string indicated by the program definition file is included in the control information, the control unit 143 refers to the program definition file and identifies the program corresponding to the character string. The control unit 143 controls devices such as the mobile communication unit 104, the short-range wireless communication unit 105, and the imaging unit 107 by calling the specified program.

  In addition, the control unit 143 acquires data from the device. For example, the image data obtained by the image capturing unit 107 from the image capturing unit 107 is acquired. For example, the barcode value read by the barcode reader 12 is acquired from the short-range wireless communication unit 105. The control unit 143 stores information indicating data received from the device in the file I / O unit 120. This is because the HTML processing unit 141 executes processing based on data acquired from the device. For example, the HTML processing unit 141 can display data acquired from the device on the display 108a. Further, the HTML processing unit 141 can transmit the selected data to the server 200.

  Here, the client 100a according to the third embodiment is an example of the information processing apparatus 1 according to the first embodiment. Moreover, the determination part 142 is an example of the determination means 1e. The control unit 143 is an example of the control unit 1f.

  The client 100 a having such a configuration can execute the same processing as that of the client 100. Specifically, the determination unit 142 performs the processing of the determination unit 151 of the second embodiment. In addition, the control unit 143 performs the processing of the control unit 152 of the second embodiment.

As described above, the functions of the determination unit 142 and the control unit 143 may be provided in the Web browser 140a. In this case, the same effect as that of the second embodiment can be obtained.
The device control program, the information processing apparatus, and the device control method of the present invention have been described above based on the illustrated embodiments. However, the present invention is not limited to these, and the configuration of each unit is an arbitrary configuration having the same function. Can be substituted. Moreover, other arbitrary structures and processes may be added. Further, any two or more configurations (features) of the above-described embodiments may be combined.
