Abstract

In a control method of a control system including a terminal configured to execute an application, a device configured to send or receive data, and a controller connected to the device, a request for a device control is transmitted from the application to the controller. At the controller, the device control by the controller is established after the controller receives the request. At the terminal, the device control by the application through the controller is established after establishing the device control by the controller.

Claims

1. A control method of a control system including a terminal configured to execute an application, a device configured to send or receive data, and a controller connected to the device, the method comprising:

transmitting a request for a device control from the application to the controller;

establishing, at the controller, the device control by the controller, after the controller receives the request; and

establishing, at the terminal, the device control by the application through the controller, after the establishing the device control by the controller.

2. The control method of claim 1, wherein the establishing the device control by the controller comprises enabling the device to execute a process in response to a further request from the terminal.

3. The control method of claim 1, wherein the establishing the device control by the controller comprises enabling data communication between the device and the terminal via the controller.

4. The control method of claim 1, wherein the establishing the device control by the controller comprises instantiating, at the controller, a control object configured to handle data communication between the device and the application.

5. The control method of claim 4, wherein the establishing the device control by the application through the controller comprises instantiating, at the terminal, an interface object configured to communicate with the control object.

6. The control method of claim 5, further comprising deleting at least one of the control object or the interface object upon release of the device control.

7. The control method of claim 5, further comprising:

upon an interruption of a connection between the terminal and the controller, attempting to re-establish the connection; and

deleting the control object at the controller when the connection is not re-established within a predetermined time period.

8. The control method of claim 7, further comprising, when the connection is re-established:

sending to the controller a data identification information (ID) of data that was received at the application from the device prior to the interruption of the connection; and

based on the data ID, retransmitting to the terminal data that was not received by the application due to the interruption.

9. A control system, comprising:

a device configured to send or receive data;

a terminal including

a terminal control unit configured to execute an application configured to output a request for control of the device by the application, and

a first communication module configured to transmit the request of the application; and

a controller including

a second communication module configured to connect with the first communication module to receive the request from the application,

an interface configured to connect to the device, and

a controller control unit;

wherein

the controller control unit is configured to, in response to the request received from the application via the first and second communication modules, instantiate a control object configured to communicate with the device via the interface,

the terminal control unit is configured to, in response to instantiation of the control object, instantiate an interface object configured to communicate between the control object and the application, and

the control object and the interface object are configured to enable the control of the device by the application via the interface, the control object, the first and second communication modules, and the interface object.

10. The control system of claim 9, further comprising a further device configured to send or receive data, wherein

the interface is configured to connect to the further device,

the controller control unit is configured to instantiate a further control object configured to communicate with the further device via the interface,

the terminal control unit is configured to instantiate a further interface object configured to communicate between the further control object and the application, and

the further control object and the further interface object are configured to enable control of the further device by the application via the interface, the further control object, the first and second communication modules, and the further interface object.

11. The control system of claim 10, wherein

the device is one selected from the group consisting of a scanner, a printer, a display and a cash drawer, and

the further device is another one selected from the group consisting of the scanner, the printer, the display and the cash drawer.

12. The control system of claim 11, wherein

the terminal comprises a table computer, and

the first and second communication modules are configured to establish a wireless communication link between the tablet computer and the controller.

13. The control system of claim 9, wherein the terminal control unit is configured to delete the interface object upon release of the control of the device by the application.

14. The control system of claim 13, wherein the controller control unit is configured to delete the control object upon the release of the control of the device by the application.

15. The control system of claim 9, wherein

upon an interruption of a connection between the terminal and the controller, at least one of the terminal control unit or the controller control unit is configured to attempt to re-establish the connection;

and

the controller control unit is configured to delete the control object when the connection is not re-established within a predetermined time period.

16. The control system of claim 15, wherein, upon the connection being re-established,

the terminal control unit is configured to send to the controller control unit a data identification information (ID) of data that was received at the application from the device prior to the interruption of the connection, and

based on the data ID, the controller control unit is configured to retransmit to the terminal data that was not received by the application due to the interruption.

17. A controller of a control system, the control system further including a terminal configured to execute an application and a device configured to send or receive data, the controller comprising:

a communication module configured to connect with the terminal to receive a request for control of the device from the application;

an interface configured to connect to the device; and

a controller control unit configured to, in response to the request received from the application, instantiate a control object,

wherein the control object is configured to

communicate with the device via the interface, and

communicate with an interface object instantiated at the terminal, to enable the control of the device by the application via the interface, the control object, and the interface object.

18. The controller of claim 17, wherein the controller control unit is configured to delete the control object upon receiving from the application a request to release the control of the device by the application.

19. The controller of claim 18, wherein, upon an interruption of a connection between the terminal and the controller, the controller control unit is configured to

attempt to re-establish the connection, and

delete the control object when the connection is not re-established within a predetermined time period.

20. The controller of claim 19, wherein, upon the connection being re-established and based on a data identification information of data that was received at the application from the device prior to the interruption of the connection, the controller control unit is configured to retransmit to the terminal data that was not received by the application due to the interruption.
