  By the way, as a means for charging the portable terminal of the order entry system, a device called a cradle as a charger is generally prepared. The terminal is charged by attaching it to the cradle as it is.

  However, for applications such as restaurants, where the mobile terminal is frequently operated, it takes into account the time it takes to start up after the power is turned on, and it is attached to the cradle in a suspended state without turning off the terminal. Often left. Although the terminal can be charged even when the power is on, if the current is saturated on the cradle side at that time, it becomes difficult for the cradle to detect the presence of the terminal. As a result, charging may end without reaching full charge, resulting in a problem that the terminal frequently falls short of power and hinders business operations.

  The present invention has been made in view of the above problems, and an object thereof is to provide a technique capable of avoiding a failure caused by insufficient charging of a mobile terminal in an order entry system in operation.

  An order entry system according to the present invention includes a portable terminal device driven by a storage battery and having an infrared communication mechanism, and a charging device that charges the storage battery via a terminal of the portable terminal device and has an infrared communication mechanism, The portable terminal device has means for resuming operation when a predetermined period elapses after shifting to the hibernation state and stopping power supply when the charging device is detected by infrared communication at the time of resumption.

  The charging method according to the present invention includes a step in which a portable terminal device driven by a storage battery and having an infrared communication mechanism resumes operation when a predetermined period has elapsed after shifting to a dormant state; Charging the storage battery via the terminal and stopping the power supply when a charging device having an infrared communication mechanism is detected by infrared communication.

  According to the present invention, even when the mobile terminal is mounted on the cradle in the suspended state, the power supply is automatically shut off, so that full charge is easily realized. Thereby, the failure of the terminal resulting from insufficient charging can be avoided. Further, since the operation of turning off the power supply every time charging is not required, the convenience in handling the portable terminal is enhanced.

<< First Embodiment >>
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the configuration of the order entry system 100 of this embodiment. The order entry system 100 includes an HT 16 that is a portable terminal for receiving customer orders, and devices described later are communicably connected by a wired LAN HUB (hub) 10 such as Ethernet (registered trademark). Take the configuration.

  The HUB 10 includes a POS terminal 11 having a register function, an OES_C 12 that is a controller of the system, a WAP 13 that is an access point for wireless LAN communication using the HT 16, and a cradle 14 that is a device that charges the HT 16. And a KP (kitchen printer) 15 that outputs order contents in a kitchen or floor.

  In the order entry system 100, when order data is transmitted from the HT 16, this is transmitted to the OES_C 12 via the WAP 13. The OES_C 12 sends the received data to the KP 15 and the POS terminal 11. The POS terminal 11 performs accounting processing based on the order data.

  FIG. 2 shows the internal configuration of the cradle 14 and the HT 16. The cradle 14 includes a charging circuit 30 electrically connected to the charging terminal 30 </ b> A and an infrared communication unit 31 that performs infrared communication with the HT 16.

  As shown in FIG. 2, the HT 16 includes a rechargeable battery 20 electrically connected to the charging terminal 20A, a CPU 21, an ADC (analog / digital converter) 22 for taking in power from the battery 20, and a start key. 23, a power control circuit 24 for controlling power supply based on an input from 23, a display control circuit 26 for controlling a display device 25 such as a display (LCD) or a lamp (LED), and an infrared ray with other devices such as the cradle 14. An infrared sensor 27 and an infrared communication circuit 28 for performing communication are provided.

  The HT 16 operates when the CPU 21 executes a program stored in its own storage device (not shown). As its basic operation, the HT 16 is in an idle state when the transmission of order data is completed while the power is on, or when there is no input from the start key 23 for a predetermined period such as 5 minutes. It automatically shifts to the suspend state. In the suspended state, after the operation status immediately before that is saved, the display of the display device 25 is stopped and the operation is stopped. Then, when the start key 23 is pressed in the suspend state, the operation resumes (resumes) from the previously saved state.

  Further, the HT 16 determines whether or not the HT 16 is mounted on the cradle 14 by infrared communication with the cradle 14. In order to carry out this determination, for example, the identification information of the cradle 14 is registered in the HT 16 in advance, and the registered information is compared with the identification information acquired by infrared communication. What is necessary is just to set so that self may be mounted | worn with the cradle 14.

  The operation procedure of this embodiment including such basic operations will be described. FIG. 3 shows the flowchart. First, the HT 16 is turned on or resumed when the start key 23 is pressed when the power is turned off or in the suspended state (step A1).

  In the operating state after the start key 23 is pressed, the HT 16 transitions to the suspend state when the no-operation period has passed the predetermined period or when the input and transmission of the order data has been completed (step A2) (step A3). ). When the start key 23 is pressed again in the suspend state, normal resume processing is performed to resume operation from the situation immediately before the transition to the suspend state (step A4: button press → step A1).

  Here, a predetermined period is set in advance in the HT 16 for the non-operation period in the suspended state. In this embodiment, it is assumed that this period is set to “10 minutes”, for example.

  When the non-operation period in the suspend state reaches the specified 10 minutes (step A4: 10 minutes), the HT 16 automatically resumes while stopping the display of the display device 25 (step A5). By stopping the display during automatic resumption in this way, it is possible to suppress the consumption of the battery, and the following processing can be executed without making the user aware of the appearance. .

  When the HT 16 automatically resumes, the HT 16 determines whether or not the HT 16 is attached to the cradle 14 by the infrared communication described above. Here, if it is determined that the cradle 14 is not mounted, that is, if charging is not being performed, the process returns to the suspended state (step A6: No → step A3).

  On the other hand, when the attachment to the cradle 14 is detected due to charging (step A6: Yes), the HT 16 automatically shuts off the power supply (step A7). Thereby, HT16 can continue charge in the state of power supply OFF.

  According to the first embodiment described above, even when the HT 16 in the suspended state is mounted on the cradle 14, the power is automatically turned off, so that it can be fully charged quickly. In addition, since it is not necessary to turn off the power by a store clerk or the like when charging, the convenience for the user is enhanced.

  In order to realize the procedure as shown in FIG. 3, on the program, a resume by pressing a button (step A1) and an automatic resume by lapse of time (step A5) are distinguished.

  Specifically, for example, when Embedded Visual C ++ is used as a programming language, “Ret = HtapiSuspend (argument 1, argument 2)” is prepared by the HtapiSuspend function, and “resume” is performed for the argument (argument 1, argument 2). ”Key” and “time until automatic resume” are set. Then, during actual operation, the type of resume is determined based on the return value (Ret) of the above function, and processing according to the determination result proceeds. For example, when the return value (Ret) corresponds to “time until automatic resume”, the HT 16 shifts to a process of searching for the cradle 14 by infrared communication while stopping the display.

<< Second Embodiment >>
The second embodiment of the present invention proposes a charging method that takes into account the use of the HT 16 in business. Note that the system configuration of this embodiment and the internal configuration of the HT16 / cradle 14 are the same as those shown in FIGS. 1 and 2, and a description thereof is omitted here.

  The operation procedure of this embodiment will be described with reference to the flowchart of FIG. The HT 16 is turned on or resumed when the start key 23 is pressed when the power is turned off or in the suspended state (step B1). At this time, the HT 16 of the present embodiment resets a count value described later to “0” (step B2).

  In the operating state after the start key 23 is pressed, the HT 16 transitions to the suspend state when the no-operation period has passed the predetermined period or when the input and transmission of the order data has been completed (step B3) (step B4). ). When the start key 23 is pressed again in the suspended state, normal resume processing is performed (step B5: button press → step B1).

  After the transition to the suspend state, the HT 16 automatically resumes while stopping the display of the display device 25 (step B6) when the no-operation period reaches the specified 10 minutes (step B5: 10 minutes).

  The HT 16 of the present embodiment checks the remaining amount of the battery 20 when the automatic resume is performed. As a result, when the remaining amount is less than the preset value (P) (step B7: <P), that is, when the remaining battery amount is less than the specified value, the power supply is automatically shut off (step B11). As the value (P) used for the determination of the remaining battery level, for example, a threshold that is predicted to have an effect on operation due to power shortage is adopted.

  Further, although the remaining battery capacity exceeds the specified value (step B7: ≧ P), when the attachment to the cradle 14 is detected (step B8: Yes), the power supply is performed as in the first embodiment. Is blocked (step B11).

  On the other hand, when mounting on the cradle cannot be detected, that is, charging is not being performed (step B8: No), the HT 16 adds “1” to the count value (step B9), and confirms the current cumulative total. Here, the count value of the present embodiment is a count value for recording the number of times that the HT 16 has executed the automatic resume. Therefore, the HT 16 adds “1” to the count value every time the automatic resume from the suspended state is repeated.

  When the count value after addition is less than the preset number (N), such as 10 or 20, the process returns to the suspended state (step B10: <N → step B4). When the count value reaches the specified number of times (N) (step B10: = N), the power supply is automatically cut off (step B11) on the assumption that there is no expectation of use for the time being.

  As described above, in this embodiment, in addition to the case where the HT 16 detects the attachment to the cradle 14, the automatic operation is automatically performed when it is determined that the remaining battery level is not sufficient or the non-operation period is long. Control to turn off the power. As a result, battery consumption in the HT 16 can be prevented, and as a result, the battery can be fully charged more quickly during charging.
