FIG. 10 shows a screen display flowchart of the touch panel 66. In this flow, the current monitoring control unit 31 waits until the front door 42 is opened by the open / close detection unit 38 (S1).

When the open / close detection unit 38 detects that the front door 42 has been opened, the current monitoring control unit 31 determines whether or not the current monitoring device 30 is in the fourth state (S2). The fourth state is a state after an abnormality is detected in any of the terminal devices by the current measurement as described above. When the current monitoring device 30 is in the fourth state in S2, the current monitoring control unit 31 causes the touch panel 66 to display the screen of the abnormality history of FIG. 8 (S3). In the fourth state, since an abnormality has already been detected in one of the terminal devices, the operator who opens the front door 42 immediately checks the history of abnormality detection in the terminal device and responds to the abnormality detection. You can perform operations.

If the current monitoring device 30 is not in the fourth state in S2, then the current monitoring control unit 31 determines whether or not the current monitoring device 30 is in the third state (S4). The third state is the state during manual measurement as described above. When the current monitoring device 30 is in the state of being manually measured in S4, the current monitoring control unit 31 causes the touch panel 66 to display the screen of the manual measurement status (S5). Since the third state is the state during manual measurement, the operator who has opened the front door 42 can immediately check the manual measurement status and perform an operation as necessary.

If the current monitoring device 30 is not in the third state in S4, then the current monitoring control unit 31 determines whether or not the current monitoring device 30 is in the second state (S6). The second state is the state during automatic measurement as described above. When the current monitoring device 30 is in the state of being automatically measured in S6, the current monitoring control unit 31 causes the touch panel 66 to display the screen of the automatic measurement status of FIG. 7 (S7). Since the second state is the state during automatic measurement, the operator who has opened the front door 42 can immediately check the automatic measurement status and perform an operation as necessary.

If the current monitoring device 30 is not in the second state in S6, the current monitoring device 30 is in the first state, that is, the normal standby state. In this case, the current monitoring control unit 31 causes the touch panel 66 to display the measurement history screen of FIG. 9 (S8). As a result, the operator who has opened the front door 42 can immediately confirm the information about the current measurement of the terminal device.

In this way, by changing the display screen of the touch panel 66 when the front door 42 is opened according to the state of the current monitoring device 30, it is possible to display the optimum screen for each state from the beginning. The situation can be quickly grasped, and the touch panel 66 can be used to perform operations corresponding to the situation, so that the efficiency of work can be improved.

Although the embodiment of the present invention has been described above, the application of the present invention is not limited to the present embodiment and can be variously applied within the scope of the technical idea thereof. For example, the plurality of operating states of the current monitoring device 30 described in the above-described embodiment and the plurality of screen displays displayed on the touch panel 66 are merely examples, and other operating states of the current monitoring device 30 and corresponding thereto. There may be another screen display on the touch panel 66.
