Description

The embodiments of the present invention relate to an information processing device, a monitoring processing method, and a monitoring processing program executed in the information processing device.

In a monitoring and control system for buildings, water and sewage stations, dams, etc., information collected from sensors of equipment in the plant to be monitored is stored in a server via a controller or the like. Monitoring and manipulation of accumulated data is generally performed by an information processing device such as a monitoring terminal that has obtained information from a server.

Among these functions, the function of viewing the latest values recorded in the server is one of the most commonly implemented functions in the monitoring terminal. With this function, in order for the monitoring terminal to obtain the data accumulated in the server, the monitoring terminal periodically requests the latest values from the server, or the server side spontaneously transmits the latest values to the monitoring terminal periodically. Adopt a method to (There is also a method of "transmitting to the monitoring terminal only when the latest value in the server changes", but the rapid changes in the latest value may cause a high load on the server, It is often not adopted due to concerns that the value will not be consistent.)
The frequency at which the server transmits the latest values is often determined by considering the load on the server and the delay due to transmission, but there is a limit to shortening the frequency in any case, and the limit value is in units of seconds and minutes. become.

Here, the screen displays the last value transmitted from the server, so even if the latest value accumulated in the server changes at this moment, it will be reflected on the screen in the next cycle. . Therefore, a lag (delay) of up to one cycle occurs before the user looking at the monitoring terminal notices a change in the data detected by the actual sensor. If this lag is sufficiently small, it does not pose a particular problem in practical monitoring, and conventionally, special measures against this lag have rarely been taken.

However, in recent years, (1) the transmission of large amounts of data with a greater amount of information has become more common than before, and (2) the use of the cloud has progressed, creating a public network apart from the conventional closed network. Due to the increase in usage, etc., the possibility that the network will be overloaded has increased.

As a result, it becomes necessary to lengthen the transmission cycle in order to maintain the integrity of the data, and as a result, the aforementioned lag increases. Increased lag has the following negative effects:

・There is a high possibility that the value displayed on the screen will deviate from the latest value in the server detected by the actual sensor, increasing the risk of the user mistaking the displayed value for the actual latest value.

・When the user can know the actual latest value (for example, when the user sets the value on the screen by himself and waits for the screen to be reflected by the data returned from the server for this set value) , the time to wait for the reflection on the screen increases, and the user's stress increases.

- When screen update stops due to some kind of abnormality, the time it takes for the user to notice the problem increases, which increases the risk of delays in dealing with problems that have occurred.

JP 2016-173807 A

In this way, if there is a delay in receiving data and there is a discrepancy between the data recorded in the server and the value displayed on the screen, the user may make an erroneous decision, or the monitoring user may be disturbed. There was a risk of causing an increase in the burden.

The problem to be solved by the embodiments of the present invention is to reduce the impact on the user even if there is a delay in receiving data and there is a difference between the data recorded in the server and the value displayed on the screen. It is an object of the present invention to provide an information processing device, a monitoring processing method, and a monitoring processing program that can

According to the embodiment, the information processing device has a data receiving section, a screen display section, and a timer display section. The data receiving unit periodically receives data indicating the operation status of the equipment to be monitored from the server. The screen display section displays a screen showing the latest data according to the latest data received by the data reception section. The timer display unit displays a countdown timer indicating the time until the screen is updated by the screen display unit based on the regular interval.

FIG. 4 is a block diagram showing a functional configuration realized by the monitoring processing program 12E (countdown timer display program 12H) in the information processing apparatus 12 of this embodiment.

As shown in FIG. 4, the CPU 12A realizes the functions of the data receiving section 212E and the screen display section 312E by executing the monitoring processing program 12E stored in the memory 12B. Further, the CPU 12A realizes a countdown timer display section 112H by executing the countdown timer display program 12H stored in the memory 12B.

The countdown timer display unit 112H displays a countdown timer indicating the time until the monitoring screen is updated by the screen display unit 312E, based on the regular intervals at which the data reception unit 212E receives the latest data.

Next, the operation of the information processing device 12 in this embodiment will be described.

FIG. 5 is a flowchart for explaining monitoring processing by the information processing device 12 in this embodiment. FIG. 6 is a flowchart for explaining the countdown timer display processing by the information processing device 12 in this embodiment. FIG. 7 is a diagram showing an example of the monitor screen 20 displayed on the display device 12K of the information processing device 12 in this embodiment.

The CPU 12A of the information processing device 12 realizes the monitoring processing function by executing the monitoring processing program 12E.

In the monitoring process, the CPU 12A (screen display unit 312E), for example, when the monitoring target facility 2 to be monitored is specified by the user's operation on the input device 12L (step A1), the specified monitoring target facility 2 The corresponding monitoring screen is displayed on the display device 12K (step A2).

FIG. 7 shows an example of the monitoring screen 20 displayed on the display device 12K. The monitoring screen 20 shown in FIG. 7 shows an example in which “○○ water receiving station water system” is designated as the monitoring target facility 2 .

On the monitoring screen 20, for example, together with a facility configuration diagram 22 representing the water system of "○○ water receiving station water system" designated as a monitoring target, sensors and the like are detected at various places in the water system shown in the facility configuration diagram 22. Numerical values indicating the content of the data received, for example, water volume, water level, pressure, water temperature, turbidity, and pH at various points in the system are displayed. By confirming each numerical value displayed on the monitoring screen 20 , the user can grasp the status of the monitoring target equipment 2 .

Further, the CPU 12A (countdown timer display unit 112H) causes the monitor screen 20 to display the countdown timer 30 by executing the countdown timer display program 12H. The example shown in FIG. 7 shows an example in which the countdown timer 30 is arranged in the lower left corner of the monitoring screen 20. As shown in FIG.

Note that the location of the countdown timer 30 may be anywhere on the monitoring screen 20 . However, even if, for example, the monitoring target equipment 2 to be monitored is changed and the facility configuration diagram 22 is changed, the countdown timer 30 can be easily recognized on the monitoring screen 20 by placing it in a fixed location. should be placed.

The CPU 10A requests the server station 10 to transmit the latest value data at a predetermined regular interval in order to receive the data detected in the monitored facility 2 accumulated in the server station 10 (step A3).

The interval of the fixed cycle is determined for each monitoring target facility 2 to be displayed on the monitoring screen 20 in consideration of the load of the server station 10 and the delay caused by the data transmission status of the network 14 . The equipment to be monitored 2 differs in the amount of data indicating the operational status of the equipment, that is, the number of points of the monitored object whose measured values and the like are displayed on the monitoring screen 20 . Therefore, normally, the larger the number of objects to be monitored in the equipment to be monitored 2, the longer the time required from the data request until the data is received, and the longer the periodic interval. Furthermore, the periodic interval is determined so as to include the time from the data request until the data is received from the server station 10 plus the time for the presumed delay.

FIG. 8 is a diagram showing the relationship between the timing of data requests to the server station 10, the display timing of updating the monitoring screen 20, and the display timing of the countdown timer in this embodiment.

As shown in FIG. 8A, data request timings (R0, R1, R2, . . . ) are set periodically.

If there is no significant delay in receiving data from the server station 10, the CPU 10A periodically transmits data requests to the server station 10. FIG. The server station 10 transmits data indicating the latest values collected from the monitored equipment 2 to the information processing device 12 in response to a data request from the information processing device 12 .

The CPU 12A (data receiving unit 212E) receives data indicating the latest value from the server station 10 through the communication device 12C. When CPU 12A (screen display unit 312E) receives the data indicating the latest value (step A4, YES), CPU 12A displays monitoring screen 20 so as to display the data of the latest value (step A5). That is, the numerical values indicating the water volume, water level, pressure, water temperature, turbidity, pH, etc. at various points in the system shown in the facility configuration diagram 22 are updated.

After that, when the periodic period predetermined according to the equipment to be monitored 2 is reached (step A6, YES), the CPU 10A requests the server station 10 to transmit the latest value data in the same manner as described above. (Step A3). Then, when the latest value data is received from the server station 10 in response to the data request, the CPU 10A (screen display unit 312A) updates the monitoring screen 20 according to the received latest value data (step A5).

Here, the timing at which the display of the monitoring screen 20 is updated by the data request at timing (R0) in FIG. 8 is assumed to be T11.

FIG. 8B1 shows display timings for updating the monitoring screen 20 when there is no large delay in receiving data from the server station 10 (normal time). As shown in FIG. 8B1, during normal operation, the latest value data is received by data requests at periodic timings R0, R1, R2, . . . is updated.

On the other hand, the CPU 12A (countdown timer display unit 112H) controls the display of the countdown timer 30 by countdown timer display processing in accordance with the update of the monitoring screen 20 according to the latest data by the monitoring processing.

That is, when the CPU 12A updates the monitoring screen 20 in response to receiving the data indicating the latest value from the server station 10 (step S1, YES), the CPU 12A resets the countdown timer 30 displayed on the monitoring screen 20 to display the initial state. The display mode is updated (step S2).

When the CPU 12A determines that the specified time for determining the timing of changing the display mode of the countdown timer 30 has elapsed while executing the monitoring process (step S3: YES), the CPU 12A displays the remaining time "0". If the display form has not been changed to the final state of the countdown timer 30 (step S4, NO), the countdown timer 30 is updated to the display form corresponding to the elapsed specified time (step S5).

FIG. 9A shows a display example of the countdown timer 30 in this embodiment. The countdown timer 30 shown in FIG. 9A shows an example of a circular display form. In FIG. 9A, the left side shows the display form in the initial state, the center shows the display form changed so that the fan-shaped range expands with the passage of time, and the right side shows the display form in the final state. there is

In the countdown timer display process, the CPU 12A changes the display mode with the passage of time in accordance with the period at which the monitor screen 20 is updated during normal operation. That is, as shown in FIG. 8(B2), the display mode is changed from the initial state to the final state at timings T11 to T12, T12 to T13, T13 to T14, . Second, the display form of the countdown timer 30 is changed with the passage of time.

Therefore, for example, after the countdown timer 30 is reset to the initial state at the timing T11 when the display of the monitoring screen 20 is updated, the countdown timer 30 is in the final state at the next timing T12 when the display of the monitoring screen 20 is updated. Thus, the display mode of the countdown timer 30 is changed each time the specified time elapses.

Therefore, by checking the countdown timer 30 displayed on the monitoring screen 20, the user can grasp the next timing when the monitoring screen 20 is updated. In practice, the time required to receive data from the server station 10 may vary for each data request. will be updated.

It should be noted that the change of the display mode of the countdown timer 30 as the specified time elapses may be made in a small number of times, for example, by changing to four stages, or may be changed continuously. When changing to four stages, for example, in the example of the countdown timer 30 shown in FIG. 9A, the change is made for each 90° circular range. Further, in the case of continuous change, for example, in the example of the countdown timer 30 shown in FIG.

FIG. 8(C1) shows the update display timing of the monitoring screen 20 when data reception from the server station 10 is delayed.

In the example shown in FIG. 8(C1), when receiving data of the latest values by data requests at periodic timings R0, R1, R2, . , T22, T23, .

As described above, the CPU 12A updates the monitoring screen 20 in response to receiving the data indicating the latest value from the server station 10 (step S1, YES), and resets the countdown timer 30 displayed on the monitoring screen 20 at this timing. (step S2).

When the time for changing the display form of the countdown timer 30 from the initial state to the final state is the same as the display timing shown in FIG. 8B2, as shown in FIG. The display of the monitoring screen 20 is updated after the countdown timer 30 is changed to the display form of the final state by the increased amount.

However, since the countdown timer 30 was reset at the timing of the last update of the monitoring screen 20, the monitoring screen 20 is updated according to the timing of changing the display form of the countdown timer 30 to the final state and the data of the latest value. There is no big gap in the timing to be done. Therefore, the user can recognize the approximate time until the monitoring screen 20 is updated by the countdown timer 30 .

Further, when the delay becomes a steady state, the countdown timer 30 reaches the final state at substantially the same timing as the monitoring screen 20 is updated in the same manner as the cases shown in FIGS. 8B1 and 8B2. The display mode is changed. Therefore, by checking the countdown timer 30 displayed on the monitoring screen 20, the user can grasp the next timing when the monitoring screen 20 is updated.

In addition, in the above description, as shown in FIG. 8B2, the countdown timer 30 is changed to the display form of the final state in accordance with the timing when the monitoring screen 20 is updated in the normal state. As shown in FIG. 8C1, even while the delay is increasing, the countdown timer 30 may not be changed to the final state display form before the monitoring screen 20 is updated.

That is, in the countdown timer display process, the CPU 12A changes the display mode of the countdown timer 30 as time passes, in accordance with the period of time when the monitoring screen 20 is updated in the normal state plus an assumed delay time. change. In this case, the display mode of the countdown timer 30 is changed to the final state at the timing when the time including the delay time has passed. Therefore, the countdown timer 30 does not reach its final state before the monitoring screen 20 is updated even if there is a delay from the normal time. Therefore, the user is not stressed because the monitor screen 20 is not updated even when the countdown timer 30 reaches the final state. Also, even if the monitor screen 20 is updated before the countdown timer 30 reaches its final state, the monitor screen 20 is updated earlier than the timing expected by the user, which may make the user feel uncomfortable. Nor.

9B and 9C show an example of another display form of the countdown timer 30. FIG.

FIG. 9B is an example showing the countdown timer 30 with a design representing an hourglass. In FIG. 9B, the left side shows the display form in the initial state, the center shows the display form changed so as to show that the sand at the top is falling to the bottom as time passes, and the right side shows the final state. is shown.

FIG. 9C is an example showing the countdown timer 30 by a bar graph and showing the remaining time to the final state (time ratio from the initial state to the final state) by numbers. In FIG. 9(C), the top is a display form indicating that 30% of the total time from the initial state to the final state has passed and the remaining 70%, and the bottom is 70% of the total time. has elapsed and the remaining 30%. In the example shown in FIG. 9C, the elapsed time is indicated numerically together with the figure representing the countdown timer 30, so that the user can clearly recognize the elapsed time (remaining time).

It should be noted that the countdown timer 30 may have display forms other than those shown in FIGS. 9A, 9B, and 9C.

In addition, the countdown timer 30 not only changes its display form with the lapse of time, but also changes the final state by changing another display form, such as blinking the countdown timer 30 or changing the display color. The user may be made to recognize the time to.

Furthermore, in the above description, one countdown timer 30 is displayed on the monitoring screen 20, but a plurality of countdown timers 30 may be displayed.

For example, in one monitoring screen 20, when displaying two systems of the equipment to be monitored 2 at the same time, two countdown timers 30 corresponding to each system are displayed. In this case, it is assumed that the data collected from the two systems of the equipment to be monitored 2 are received from the server station 10 at different regular intervals. The CPU 12A updates the numerical value of each system displayed on the monitoring screen 20 for each data received at different periodic intervals corresponding to each of the two systems, and displays two countdown timers in the same manner as described above. Let

Alternatively, the systems of the two monitoring target facilities 2 may be displayed on different monitoring screens 20, and the countdown timer 30 updated based on a different fixed cycle may be displayed on each monitoring screen 20. For example, if there are 200 monitoring targets in the system of the first monitoring target facility 2 and 1000 monitoring targets in the system of the second monitoring target facility 2, the first monitoring target facility 2 has 10 monitoring targets. It is assumed that data is received in a cycle of seconds, and data is received in a cycle of one minute for the system of the second monitored equipment 2 because it has more points than the first monitored equipment 2 . In this case, when the system of the first monitoring target equipment 2 is displayed on the monitoring screen 20, the CPU 12A displays the countdown timer 30 which is updated based on the period of 10 seconds. Further, when the system of the second monitored equipment 2 is displayed on the monitoring screen 20, the CPU 12A displays a countdown timer that is updated on a one-minute cycle.

As a result, the display of the countdown timer 30 makes it possible to recognize the timing at which the monitoring screen 20 is updated according to the latest value data for each of the monitoring target facilities 2 of the two systems.

In the information processing apparatus 12 according to the present embodiment, in order to maintain the integrity of the data or because the amount of data to be received is large, the fixed period for receiving data from the server station 10 becomes longer, and the value displayed on the monitor screen 20 and the By displaying the countdown timer 30 on the monitoring screen 20, even if there is a high possibility that the data displayed on the server station 10 will deviate from the latest value, the user can check the displayed value on the monitoring screen 20 from the actual latest value. It is possible to make it difficult to misidentify as

In addition, when the user sets the value of the monitor screen 20 by himself and waits for the monitor screen 20 to be reflected by the data returned from the server station 10 with respect to the set value, the countdown timer 30 updates the monitor screen 20. Since the user can be made aware of the time until the time, the user does not have to be stressed. Therefore, after setting a value on the monitoring screen 20, the user desperately wants to display the latest value immediately, and continuously presses the update button of the monitoring screen (for example, a browser), which may cause the server station 10 to overwork. It is also possible to prevent a situation in which a load is applied.

Also, if the updating of the monitoring screen 20 is stopped due to some abnormality, by confirming that the monitoring screen 20 is not updated even after a sufficient time has passed after the countdown timer 30 reaches the final state, Since it is possible to easily determine that an abnormality has occurred, it is possible to reduce the time required for the user to notice the occurrence of an abnormality, and to promptly implement a response to the abnormality that has occurred.

By displaying the countdown timer 30 indicating the time until the monitoring screen 20 is updated in this way, even in a situation where a delay occurs before the information processing device 12 acquires the latest value data from the server station 10, Even if there is, it does not cause the user to make an erroneous judgment or increase the burden on the monitoring user.
