The storage unit 12 stores signals from the sensors 6a to 6c together with identification information and time information of the sensors 6a to 6c. The identification information of the sensors 6a to 6c means information such as the type, model number, signal type, and installation time of the sensors 6a to 6c. In addition to the information on the sensors 6a to 6c, the information on the device in which the sensors 6a to 6c are provided may be added to the identification information.

The storage unit 12 is configured by a storage medium such as a hard disk, and stores information regarding the sensors 6a to 6c and the like. The graph display unit 13 causes the display 8 of the management terminal 7 to display the signals from the sensors 6a to 6c or the signals stored in the storage unit 12 as a time-series graph together with time information. The selection unit 14 enables selection of a graph within a desired range of time width for the graph display 21 in the display 8 displayed by the graph display unit 13 (see FIG. 3).

The comment input unit 15 displays a comment input screen 22 for the area selected by the selection unit 14, and enables comment input via a comment input field 23 (see FIG. 3). The list display unit 16 displays the input comments and time information as a comment list 31 on the display 8 (see FIG. 4).

The management terminal 7 is a terminal used by an operator, and can be a personal computer, a tablet terminal, or a smart phone equipped with a display 8 . In this embodiment, the display 8 has a touch panel function, and when displaying the graph display 21 by the graph display unit 13, the operator can select a desired range of the graph display 21 with a finger. It has become.

The sensors 6a to 6c include an ammeter for measuring the current supplied to the device, a water meter for a pump for controlling the water flow of cooling water, etc., and a flow rate for measuring the flow rate of air supplied to the device using air pressure. Various sensors such as a thermometer for measuring the temperature of a device are applicable.

By managing the values of the respective sensors 6a to 6c using the equipment management system 1 of this embodiment, the status of the equipment in the factory 2 is monitored, and when abnormal data is detected, the abnormal sensor 6a 6c can be identified and maintenance such as repair can be performed.

Next, the comment input function in the device management system 1 of this embodiment will be described with reference to FIG. The device management system 1 of this embodiment includes a graph display section 13 that displays the values of the sensors 6a to 6c together with time information as a time-series graph on the display 8. FIG. As shown in FIGS. 3A to 3D, the graph display unit 13 can display a graph display 21 with the horizontal axis as the time axis and the vertical axis as the levels of the detection values of the sensors 6a to 6c.

In FIG. 3A, sensor A ( 6 a ) is a sensor that detects the filtration flow rate of a filter (not shown) that filters water used in factory 2 . Sensor B (6b) is a current sensor that detects the current of the pump that circulates the water supplied to the filter. Sensor C (6c) is a chromaticity sensor that detects the chromaticity of filtered water.

The information of the graph display 21 is provided with a sensor display indicating which graph the values of the sensors 6a to 6c correspond to. In FIG. 3, a representation of sensor A (6a), sensor B (6b) and sensor C (6c) is provided.

In FIG. 3, the line of the graph showing the detection value of sensor A (6a) is a dashed line, the line of the graph showing the detection value of sensor B (6b) is a solid line, and the graph showing the detection value of sensor C (6c) is Although the lines are represented by dotted lines, the colors are actually displayed in different colors for each sensor.

When entering a comment, the sensor for which the comment is to be entered is specified. For example, as shown in FIG. 3A, the operator taps the display of sensor A (6a), which is the target sensor. In the graph display 21, the color of the line of the graph of sensor A and the color of the portion labeled sensor A (6a) are displayed in the same color. As a result, the operator can easily visually confirm which sensor's graph is to be commented on.

Next, as shown in FIG. 3B, the operator presses the start time portion of the graph for which he/she wishes to enter a comment. Next, the operator swipes the finger to the end time of the desired range, as shown in FIG. 3(C). By such an operation, as shown in FIG. 3C, the screen in the range swiped with the finger is given the same color as the sensor A (6a). Therefore, the operator can easily check whether the graph for which he or she is going to enter a comment has been specified correctly.

When the operator has finished selecting the time width within the desired range, a comment input screen 22 is displayed on the graph display 21 as shown in FIG. 3(D). The comment input screen 22 displays the start time and end time of the time span selected by the operator. A comment input field 23 is displayed below the display of the time width. A keyboard provided in the management terminal 7 can be used to enter the comment in the comment input field 23 . Characters can also be input from a soft keyboard, or can be input by voice or the like.

After completing the input in the comment input field 23 , the operator saves the input content by pressing the save button 24 . By tapping the save button 24, the comment input in the comment input field 23, the time data of the time width selected by the operator, and the identification information of the sensor 6a are stored in the storage unit 12. FIG. On the other hand, when the time span is selected incorrectly, the cancel button 25 can be tapped to select the time span again.

The saved comments can be confirmed in a comment list 31 displayed by the list display section 16, as shown in FIG. The comment list 31 can display comments of a plurality of sensors 6a to 6c, and can also display comments of only one sensor, for example, the sensor 6a.

When comments of a plurality of sensors 6a to 6c are displayed in the comment list 31, it is possible to get a bird's-eye view of which device in the factory 2 has a problem. On the other hand, when the comment list 31 displays the comments of the same sensor, for example, only the sensor 6a, it is possible to confirm the comments of the sensor 6a in chronological order from the past to the present. Therefore, it is possible to check the change of the data of the sensor 6a with time and predict the failure of the equipment.

In the above-described embodiment, the desired time period is selected by the selection unit 14 by swiping by the operator. It may be performed by directly inputting the start time and the end time from a keyboard or the like. Further, in the above embodiment, an example in which one plant recorder 3 and three sensors 6a to 6c are installed in the factory 2 has been described, but a plurality of plant recorders 3 may be installed, and the number of sensors 6 may be increased. A large number can be installed according to the actual conditions of the factory 2 .

In the above embodiment, the operator selects the graph on the display 8 of the management terminal 7 connected to the network 4, but the display 3a of the plant recorder 3 may also select the graph in the same way. can be
