The plant manager can view and edit plant information (data 002) via 3G / LTE by using a management terminal 70 such as a notebook computer that can be connected to 3G / LTE. As a result, the manager can remotely monitor the state of the plant equipment without going to directly monitor the plant equipment, and when an abnormal state is found, the worker carrying the mobile terminal 40 is required to perform repair work. It becomes possible to give instructions such as.

The repeater 60 shown in FIG. 2A includes a control unit 61, a network connection unit 62, a tag unit 63, a notification unit 64, and a battery 65. Further, the power supply control unit 66 may be further provided. The repeater 60 has substantially the same internal structure as the detection device 10, but differs from the detection device 10 in that it does not have a detection unit.

An example of an operation of storing information in the tag unit 14 of the detection device 10 and acquiring information from the data storage card 50 by the tag control unit 42 of the mobile terminal 40 will be described with reference to FIG. 2E. In FIG. 2E, thin arrows in the figure represent signals such as commands, and thick arrows in the figure represent power supply. Further, since the operation of storing information in the tag unit 63 of the repeater 60 by the tag control unit 42 of the mobile terminal 40 is the same, the description thereof will be omitted.

When the mobile terminal 40 is held over the detection device 10, the tag control unit 42 of the mobile terminal 40 generates, for example, a write signal generated by the tag reader / writer 42-1, and the tag control antenna 42-2 generates, for example, a radio wave or a magnetic field. Is included in the above and transmitted to the detection device 10. The tag unit 14 of the detection device 10 generates electric power in the tag antenna 14-2 by rectifying the radio waves received by the tag antenna 14-2 or by electromagnetic induction by the received magnetic field. The tag antenna 14-2 supplies the generated electric power to the tag IC 14-1, and the tag IC 14-1 is activated. When the signal included in the radio wave or magnetic field received by the tag antenna 14-2 is a write signal, the activated tag IC 14-1 stores the information included in the write signal.

As described above, when the tag control unit 42 of the mobile terminal 40 stores the information in the tag unit 14, it is not necessary to supply power to the tag unit 14 from the inside of the detection device 10. That is, even when the detection device 10 is in the power-off state or the sleep state, the tag control unit 42 of the mobile terminal 40 can store information in the tag unit 14 of the detection device 10.

Further, the tag IC 14-1 activated by the radio wave or magnetic field received by the tag antenna 14-2 outputs an activation signal to, for example, the power supply control unit 17. The power supply control unit 17 that has input the start signal supplies the power supplied from the battery 16 by the power supply control unit 17 to, for example, at least the control unit 11. For example, when the power-supplied control unit 11 is activated, the detection device 10 is turned on. That is, the detection device 10 is configured to be in the power ON state when the information is stored in the tag unit 14 by the tag control unit 42 of the mobile terminal 40. When the power of the detection device 10 is ON, the control unit 11 supplies electric power to the tag IC 14-1 of the tag unit 14, so that the control unit 11 stores information in the tag IC 14-1 and tags. Information can be obtained from IC14-1.

Further, when the detection device 10 in the power ON state goes into the power OFF state or the sleep state, the control unit 11 outputs a stop signal or a sleep signal to the power control unit 17. The power supply control unit 17 that has input the stop signal or the sleep signal, for example, stops the power supply to at least the control unit 11 or reduces the amount of the power supply. For example, when the power supply to the control unit 11 is stopped, the detection device 10 is turned off, and when the amount of power supply to the control unit 11 is reduced, the detection device goes to sleep.

On the other hand, when the mobile terminal 40 is held over the data storage card 50, the tag control unit 42 of the mobile terminal 40 generates, for example, a read signal generated by the tag reader / writer 42-1 by the tag control antenna 42-2, for example. It is included in a radio wave or a magnetic field and transmitted to the data storage card 50. The data storage card 50 generates electric power in the antenna 52 by rectifying the radio waves received by the antenna 52 or by electromagnetic induction by the received magnetic field. The antenna 52 supplies the generated electric power to the IC 51, and the IC 51 is activated. When the signal contained in the radio wave or magnetic field received by the antenna 52 is a read signal, the activated IC 51 includes the information stored in the IC 51 in response to the read signal in the radio wave or magnetic field generated by the antenna 52. Send back. The tag control unit 42 of the mobile terminal 40 receives the returned radio wave or magnetic field with the tag control antenna 4-2, and transmits the information contained in the radio wave or magnetic field to the tag reader / writer 42-1. As a result, the information of the data storage card 50 is stored in the tag reader / writer 42-1.

As described above, when the tag control unit 42 of the mobile terminal 40 acquires information from the data storage card 50, the operator does not need to perform a complicated input operation by a manual operation such as using a touch panel type display module. .. That is, the tag control unit 42 of the mobile terminal 40 can store the information necessary for the work without causing an input error or a confirmation time of the input contents.

Next, an example of the state transition of the mobile terminal 40 and the operation of the light emitting unit 44 and the buzzer 45 will be described with reference to FIGS. 2F, 2G, and 2H.

FIG. 2F shows the state transition of the mobile terminal 40. When the event EV10 in which the slide switch 40-2 is turned on occurs in the power-off state ST10, the mobile terminal 40 turns on the power and transitions to the inactive state ST20. At this time, the mobile terminal 40 performs the initialization process (initial process) PC10.

Initialization processing In the PC10, the light emitting unit 44 is stopped after the tag control unit 42 is initialized and self-diagnosis processing for determining whether or not it functions normally, and the tag control unit 42 is stored in the storage unit 43. The read information acquired by 42 is deleted.

The inactive state ST20 is a standby mode that mainly monitors the switch input, and is also a power saving mode that omits other functions. The inactive state ST20 stops at least the tag control unit 42 and the light emitting unit 44. The mobile terminal 40 transitions to the active state (operation mode) ST30 when the event EV20 in which the push switch 40-3 is turned on occurs in the inactive state ST20. At this time, the tag control unit 42 of the mobile terminal 40 is activated, and the read information load processing PC 20 for reading the read information stored in the storage unit 43 is performed. If there is no read information stored in the storage unit 43, the read information is not performed.

Further, when the slide switch 40-2 off event EV30 occurs in the inactive state ST20, the mobile terminal 40 transitions to the power off state ST10. The active state ST30 is a mode in which all the functions of the mobile terminal 40 can be executed, and the tag control unit 42 and the light emitting unit 44 are activated. The state transition in the active state ST30 will be described later with reference to FIG. 2G. When the event EV40 with the push switch 40-3 off occurs when the mobile terminal 40 is in the active state ST30, the mobile terminal 40 transitions to the inactive state ST20.

This will be described using a processing flow.

When the event EV10 in which the slide switch 40-2 is turned on occurs in the power-off state ST10, the control unit 41 turns on the power and transitions to the inactive state (standby mode) ST20. At this time, the initialization processing PC10 described above is performed.

At this time, as a self-diagnosis process of the initialization process (initial process) PC10, the control unit 41 acquires information on the remaining battery level (remaining capacity) of the battery 46 from the power supply control unit 47 (step S1). Based on the information, it is determined whether or not the remaining battery level of the battery 46 is equal to or higher than a predetermined value (step S2).

When it is determined by the determination process in step S2 that the remaining battery level is less than the predetermined value, the control unit 41 shifts the system to the error mode and uses the buzzer 45 for notifying the operator that the remaining battery level is low. , A warning sound is generated, and the system shifts to the power off state (stop mode) ST10 (step S3).

When it is determined by the determination process in step S2 that the remaining battery level is equal to or higher than a predetermined value, the control unit 41 reads out the information saved during normal operation from the storage unit 43 (step S4), and power saving mode (step S4). It shifts to the inactive state ST20) (step S5).

FIG. 3B shows a process related to a timeout after shifting to the power saving mode after startup. In order to monitor the input operation of the push switch 40-3, the control unit 41 determines whether or not the push switch 40-3 has changed from the off state to the on state (step S51).

Based on this determination, when the push switch 40-3 is turned on, it is regarded as communication permission, and the control unit 41 is temporarily active as described above while operating the tag control unit 42 and the storage unit 43. The state shifts to ST30 and communication processing is performed (step S52).

Next, the control unit 41 performs a continuous pressing determination process to determine whether the pressed push switch 40-3 has been pressed for a certain period of time (for example, 5 minutes) (step S53). Further, the control unit 41 performs a non-operation determination process for determining whether or not the push switch 40-3 has been operated within a certain time (for example, 1 hour) (step S54).

The control unit 41 sounds the buzzer 45 when the push switch 40-3 is continuously pressed for a certain period of time or there is no operation for a certain period of time by a continuous pressing determination or a non-operation determination (step S55). After alerting the person, the power control unit 47 is used to shift to the power off state (stop mode) (step S56). As a result, when the operator unintentionally enters the operation mode or the power saving mode, such as forgetting to turn off the slide switch 40-2 or sticking the push switch 40-3, the mode is automatically switched to the stop mode. It is possible to prevent the transition and the extra power consumption of the mobile terminal 40 from being consumed. Further, since the power supply is stopped while the slide switch 40-2 is in the off state, this can be notified to the operator by the alarm output. When performing this alarm output, the control unit 41 can perform the same processing as in steps S1 and S2 again to notify that the remaining capacity of the battery 46 is insufficient. Further, the alarm output can be output not only by the sound of the buzzer 45 but also by the lighting or blinking of the light emitting unit 44. It is also possible to make it possible to identify a plurality of alarm contents by differentizing the frequency and cycle of ringing, the blinking pattern and color of light emission, the lighting order, and the like.

Further, the control unit 41 can, of course, monitor the input of the slide switch 40-2 (step S57) and turn off the power according to the off operation (step S56). If the slide switch 40-2 is in the on state and the power is turned off, the mobile terminal 40 can be started again by performing the slide operation of turning the slide switch 40-2 off and on. ..

By repeating the processes of steps S51 to S57, the mobile terminal 40 is provided with a time-out function capable of reducing unnecessary power consumption.

According to the mobile terminal 40, the mobile terminal 40 operates the tag control unit 42 to perform wireless communication by using the electric power supplied from the battery 46, and turns on / off the electric power supply from the battery 46. The slide switch 40-2 for switching, the push switch 40-3 for switching the permission / prohibition of communication by the tag control unit 42, and the slide switch 40-2 are on and the push switch 40-3 is permitted. Based on the transition to the state, the operation mode (active state ST30) for operating the tag control unit 42 using the power and the power saving for monitoring the signal input from the slide switch 40-2 or the push switch 40-3. A control unit 41 for switching between a mode (inactive state ST20) and a stop mode (power off state ST10) for cutting off the power supply from the battery 46 is provided, and the control unit 41 is provided after the slide switch 40-2 is turned on. As an initial process, a remaining capacity determination process (step S2) for determining whether or not the remaining amount of the battery 46 is less than a predetermined value is performed, and when the remaining capacity is less than the predetermined value, the mode shifts to the stop mode.

Therefore, since the mobile terminal 40 can confirm a sufficient remaining capacity for work at the time of startup, it is possible to prevent the mobile terminal 40 from being forced to prepare a power source such as charging work or battery replacement work during the work, so that the mobile terminal 40 is highly convenient to carry. It becomes a type management device.

Further, since the mobile terminal 40 is provided with a time-out function, wasteful power consumption can be suppressed and the frequency of charging and battery replacement can be reduced, so that the mobile terminal 40 becomes a highly convenient portable management device.
