[Configuration and basic operation]
FIG. 1 is a diagram showing a configuration of a monitoring system according to an embodiment of the present invention.

With reference to FIG. 1, the monitoring system 101 includes a plurality of sensors 11, a sensor management device 12, a display 13, and a wireless communication device 14. The sensor management device 12 may be configured to include the display 13.

The sensor 11 includes the battery 15 and operates by the electric power supplied from the battery 15. The sensor 11 is installed in a monitoring area such as a factory or a hospital, and measures the monitored object, for example, temperature, humidity, current, or the like.

The sensor 11 periodically or irregularly creates sensor information including its own identification information, that is, an ID (Identification), measurement result information indicating the measurement result, and battery information regarding the remaining charge of the battery 15, for example, wirelessly. The created sensor information is wirelessly transmitted to the wireless communication device 14 according to a communication method such as LAN (Local Area Network) or ZigBee (registered trademark). The battery information indicates, for example, the voltage of the battery 15.

The wireless communication device 14 is, for example, a base station in a wireless LAN, ZigBee, or the like, and transmits sensor information received from the sensor 11 to the sensor management device 12.

Specifically, when the wireless communication device 14 receives a wireless signal including the sensor information from the sensor 11, the wireless communication device 14 adds communication quality information indicating LQI (Link Quality Indicator) at the time of receiving the sensor information to the sensor information. , The sensor information to which the communication quality information is added is transmitted to the sensor management device 12.

The sensor management device 12 receives sensor information of each sensor 11 from the wireless communication device 14, and controls the display 13 to display the contents based on the received sensor information.

FIG. 2 is a diagram showing an example of a screen displayed on a display in the monitoring system according to the embodiment of the present invention.

FIG. 2 shows, for example, a screen created by an application AP installed in the sensor management device 12. The application AP periodically updates the screen based on, for example, the sensor information received by the sensor management device 12.

With reference to FIG. 2, the screen Pi2 includes a data display area Td, a graph display area Md, a button display area Ad, a battery display area Bd, a communication display area Cd, and a log display area Ld.

In the data display area Td, for example, the contents of the latest sensor information from the selected sensor 11 are displayed. Specifically, the data display area Td is measured by the "temperature", "humidity" and "battery voltage" measured by the sensor 11 having the ID "12e3", that is, the voltage of the battery 15, and the wireless communication device 14. The value of "LQI" is displayed.

In the graph display area Md, a temperature graph and a humidity graph created based on the measurement result information included in the sensor information from the selected sensor 11 are displayed. In the battery display area Bd, a graph of a voltage capable of determining the remaining charge of the battery 15 is displayed, which is created based on the battery information included in the sensor information from the selected sensor 11.

In the communication display area Cd, an LQI graph showing the communication quality between the sensor 11 and the wireless communication device 14 created based on the communication quality information included in the sensor information from the selected sensor 11 is displayed. ..

In the log display area Ld, the history of receiving the sensor information by the sensor management device 12 and the abnormality detected by the sensor management device 12 based on the measurement result information is displayed.

The button display area Ad includes a display unit Au1 to a display unit Au8 and a display unit Se. Hereinafter, each of the display units Au1 to the display unit Au8 will also be referred to as a display unit Au.

In the example shown in FIG. 2, the monitoring system 101 includes eight sensors 11. The display units Au1 to Au8 correspond to each of these eight sensors 11.

Buttons Bu1 to Bu8 are displayed on the display units Au1 to Au8, respectively. Hereinafter, each of the buttons Bu1 to Bu8 is also referred to as a button Bu.

The latest temperature measured by the corresponding sensor 11 is displayed on the button Bu. Further, the ID of the corresponding sensor is displayed on the upper side of the button Bu. That is, each of the display units Au1 to Au8 displays the contents in which the corresponding sensor 11 and the measurement result indicated by the sensor information from the sensor 11 are associated with each other.

For example, when the sensor management device 12 receives the sensor information from the sensor 11 during the period when the screen Pi 2 is displayed, the button Bu corresponding to the sensor 11 on the screen Pi 2 blinks temporarily. As a result, the user can be made to recognize that the sensor management device 12 has received the sensor information from the sensor 11.

Further, for example, by clicking the button Bu, the user can display the contents related to the sensor corresponding to the clicked button in the data display area Td, the graph display area Md, the battery display area Bd, and the communication display area Cd. ..

Further, on the display unit Se, buttons S1 to S4 to which the characters "temperature", "humidity", "battery voltage" and "LQI" are attached are displayed.

For example, the user can select the content to be displayed on the buttons Bu1 to Bu8 by clicking any one of the buttons S1 to S4. Since the button S1 with the characters "temperature" is selected on the screen, the temperatures measured by the corresponding sensors 11 are displayed on the buttons Bu1 to Bu8.

[Task]
Immediately after starting the application AP, each button Bu and the corresponding ID are not displayed in the button display area Ad of the screen. For example, when the sensor management device 12 receives the sensor information after the application AP is activated, the button Bu corresponding to the sensor 11 that is the source of the sensor information and the corresponding ID are displayed. Then, when the sensor management device 12 receives the sensor information from the new sensor 11, the set of the button Bu and the ID is newly displayed in the button display area Ad.

Here, if the sensor management device 12 is configured to continue to display the button Bu and ID corresponding to the sensor 11 on the screen even after the sensor information from the sensor 11 cannot be received, the user can use the sensor information. Cannot easily recognize the sensor 11 which is not transmitted to the sensor management device 12.

In the list display area Gd, a list of unreceivable sensors, which is a list of IDs of unreceivable sensors, is displayed. Specifically, the non-receivable sensor list shows the identification information of the non-receivable sensor and the non-receivable cause of the non-receivable sensor.

In the button display area Ad, the content that the user can recognize the non-receivable sensor is displayed. Specifically, in the button display area Ad on the screen Pi3, the contents of the display unit Au corresponding to the non-receivable sensor among the display units Au1 to Au8 are displayed as compared with the button display area Ad on the screen Pi2 shown in FIG. It has not been. That is, the display contents of the display units Au2, Au3, Au5, Au7 have been deleted.

In this way, the sensor management device 12 changes the display on the screen so that the user can recognize the unreceivable sensor when the sensor information cannot be received from one or more sensors 11.

With reference to FIG. 4, in the button display area Ad, the content that the user can recognize the non-receivable sensor is displayed. Specifically, the display units Au2, Au3, Au5, Au7, which are the display units Au corresponding to the non-receivable sensor, display different displays than the display units Au2, Au3, Au5, Au7 on the screen Pi2 shown in FIG. It is an aspect.

More specifically, the buttons Bu2, Bu3, Bu5, and Bu7, which are the buttons Bu corresponding to the non-receivable sensor, are marked with the characters "stopped". In addition, other characters such as "reception not possible" may be attached to the buttons Bu2, Bu3, Bu5, and Bu7.

Specifically, the display units Au2, Au3, Au5, Au7, which are the display units Au corresponding to the non-receivable sensor, display different displays than the display units Au2, Au3, Au5, Au7 on the screen Pi2 shown in FIG. It is an aspect.

More specifically, the buttons Bu2, Bu3, Bu5, and Bu7, which are the buttons Bu corresponding to the non-receivable sensor, are displayed in a color different from the color in the normal display. The button Bu corresponding to the non-receivable sensor may be displayed in a color different from the color in the normal display, and may have characters such as "stopped".

[motion]
Next, the screen display process in the monitoring system according to the embodiment of the present invention will be described.

Each device in the monitoring system 101 includes a computer, and an arithmetic processing unit such as a CPU in the computer reads a program including a part or all of each step in the following flowchart from a memory (not shown) and executes the program. The programs of these plurality of devices can be installed from the outside. The programs of these plurality of devices are distributed in a state of being stored in a recording medium.

FIG. 6 is a diagram showing an example of a sequence of screen display processing in the monitoring system according to the embodiment of the present invention.

Hereinafter, among the display units Au1 to Au8 on the screen Pi2 shown in FIG. 2, the sensor 11 corresponding to the display unit Au2 is referred to as the sensor 11K. The ID of the sensor 11K is "12e4".

With reference to FIG. 6, first, the sensor 11K creates sensor information based on its own measurement result, and transmits the created sensor information to the wireless communication device 14 (step S11).

Next, the wireless communication device 14 adds communication quality information indicating the LQI when the sensor information is received to the sensor information received from the sensor 11K (step S12), and adds the communication quality information to the sensor information. It is transmitted to the management device 12 (step S13).

Next, when the sensor management device 12 receives the sensor information from the wireless communication device 14, the sensor management device 12 creates display information L indicating the display contents of the display 13 based on the received sensor information (step S14), and the created display information. L is transmitted to the display 13 (step S15).

Next, the display 13 displays the content of the display information L received from the sensor management device 12. Here, for example, the screen Pi2 shown in FIG. 2 is displayed on the display 13.

The monitoring system 101 periodically repeats, for example, the operations of steps S11 to S15.

Here, the sensor management device 12 determines from the latest sensor information reception timing from the sensor 11K that if new sensor information does not reach itself for a predetermined time, it cannot receive the sensor information from the sensor 11K, and the sensor 11K is regarded as a non-receivable sensor (step S16).

Next, the sensor management device 12 confirms the content of the latest sensor information from the sensor 11K, and determines the cause of the inability to receive the sensor information from the sensor 11K, that is, the cause of non-reception.

Specifically, for example, when the battery information included in the latest sensor information indicates that the remaining charge is low, the sensor management device 12 cannot receive the sensor 11K because the remaining charge of the battery 15 is insufficient. Judge that there is.

Further, when the communication quality information included in the latest sensor information indicates that the communication quality between the sensor 11K and the wireless communication device 14 is poor, the sensor management device 12 cannot receive the sensor 11K because the communication quality is deteriorated. Judge that there is. Here, the sensor management device 12 determines that the cause of the inability to receive the sensor 11K is insufficient storage capacity.

Next, the sensor management device 12 creates display information M indicating the display content of the display 13 based on its own judgment content (step S18), and transmits the created display information M to the display 13 (step S19). ..

Next, the display 13 displays the content of the display information M received from the sensor management device 12. For example, the screen Pi3 shown in FIG. 3 is displayed on the display 13. On the screen Pi3, the display content of the display unit Au corresponding to the sensor 11K has been deleted. Further, in the list display area Gd, a non-receivable sensor list is displayed.

In the non-receivable sensor list, the ID of the sensor 11K, which is a non-receivable sensor, and the cause of non-reception of the sensor 11K are displayed. Specifically, the unreceivable sensor list indicates that the remaining charge of the battery 15 is low as the cause of the unreceivable reception of the sensor 11K.

Although not shown in FIG. 6, the sensor management device 12 considers the sensor 11 corresponding to the display units Au3, Au5, and Au7 as a non-receivable sensor as well as the sensor 11K, that is, the sensor 11 corresponding to the display unit Au2. Create a list of unreceivable sensors on the screen Pi3.

FIG. 7 is a diagram showing another example of the sequence of screen display processing in the monitoring system according to the embodiment of the present invention.

With reference to FIG. 7, the operation of steps S31 to S35 is the same as the operation of steps S11 to S15 shown in FIG. The monitoring system 101 repeats the operations of steps S31 to S35 periodically or irregularly.

Here, for example, the user performs an operation for turning off the power of the sensor 11K. Upon receiving the operation (step S36), the sensor 11K creates operation stop information including its own ID and off information indicating that the power is turned off before stopping the operation, and creates the created operation stop. Information is transmitted to the wireless communication device 14 (step S37).

Next, the wireless communication device 14 receives the operation stop information from the sensor 11K and transmits the received operation stop information to the sensor management device 12 (step S38).

Next, when the sensor management device 12 receives the operation stop information from the wireless communication device 14, it recognizes that the sensor information from the sensor 11K cannot be received because the power of the sensor 11K is turned off (step S39). ..

Next, the sensor management device 12 creates display information N indicating the display content of the display 13 (step S40), and transmits the created display information N to the display 13 (step S41).

Next, the display 13 displays the display information N received from the sensor management device 12. Here, the display 13 displays, for example, a screen different from the screen Pi3 shown in FIG. 3 in the following points. That is, on the screen, the unreceivable sensor list displayed in the list display area Gd indicates that the cause of unreceivable reception of the sensor 11K is that the power of the sensor 11K is turned off.

FIG. 8 is a diagram showing a configuration of a sensor management device according to an embodiment of the present invention.

With reference to FIG. 8, the sensor management device 12 includes a receiving unit 21, a processing unit (determining unit) 22, a display control unit 23, and a storage unit 25.

The receiving unit 21 receives the sensor information indicating the measurement result by the sensor 11. Specifically, for example, the receiving unit 21 receives sensor information including measurement result information, battery information, and communication quality information from the wireless communication device 14, and outputs the received sensor information to the processing unit 22 and the storage unit 25. .. The storage unit 25 stores the sensor information received from the reception unit 21.

The processing unit 22 creates, for example, display information L including the contents of the screen Pi 2 shown in FIG. 2 based on the sensor information received from the wireless communication device 14, and sends the created display information L to the display control unit 23. Output.

The display control unit 23 controls to display a screen in which the measurement result indicated by the sensor information received by the reception unit 21 and the sensor 11 are associated with each other.

For example, the display control unit 23 transmits the display information L received from the processing unit 22 to the display 13. For example, the screen Pi2 shown in FIG. 2 is displayed on the display 13. On the display units Au1 to Au8 on the screen Pi2, the contents corresponding to the measurement result indicated by the sensor information and the sensor 11 are displayed.

For example, when the processing unit 22 receives the sensor information from the sensor 11K from the receiving unit 21 and then does not receive the new sensor information from the sensor 11K for a predetermined time from the receiving unit 21, the receiving unit 21 receives the sensor information from the sensor 11K. It is determined that the sensor information cannot be received, and the sensor 11K is regarded as a non-receivable sensor.

When the processing unit 22 determines that the receiving unit 21 can no longer receive the sensor information from the sensor 11K, for example, the processing unit 22 confirms the content of the latest sensor information from the sensor 11K stored in the storage unit 25, and from the sensor 11K. Determine the cause of the inability to receive the sensor information of, that is, the cause of the inability to receive.

Specifically, for example, when the battery information included in the latest sensor information from the sensor 11K indicates that the remaining charge is low, the sensor management device 12 causes the sensor 11K to be unable to receive the remaining charge of the battery 15. Judge that the amount is insufficient.

Further, the processing unit 22 considers the sensor 11 corresponding to the display units Au3, Au5, Au7 as a non-receivable sensor as well as the sensor 11 corresponding to the display unit Au2 on the sensor 11K, that is, the screen Pi2.

For example, the processing unit 22 creates display information M including the contents of the screen Pi3 shown in FIG. 3 based on its own judgment content, and outputs the created display information M to the display control unit 23.

The display control unit 23 controls to change the display content of the screen of the display 13 so that the sensor 11 that the receiving unit 21 can no longer receive the sensor information, that is, the sensor 11K which is a non-receivable sensor can be recognized.

Specifically, for example, the display control unit 23 controls to delete the content of the unreceivable sensor and the measurement result of the non-receivable sensor, that is, the content of the display unit Au2, from the screen of the display 13.

At this time, the screen displayed under the control of the display control unit 23 is, for example, a screen further showing a list of IDs of non-receivable sensors, that is, a list of non-receivable sensors.

Further, at this time, the screen displayed by the control of the display control unit 23 is, for example, a screen showing the cause that the receiving unit 21 cannot receive the sensor information from the sensor 11K, that is, the cause that the sensor 11K cannot receive. For example, when the battery information indicating that the remaining charge is low is received by the receiving unit 21, the screen indicates that the remaining charge is low as the cause of the inability to receive.

Specifically, for example, the display control unit 23 transmits the display information M to the display 13. Further, the processing unit 22 determines the communication quality between the sensor 11 and its own sensor management device 12.

Specifically, for example, when the processing unit 22 determines that the receiving unit 21 can no longer receive the sensor information from the sensor 11K, the communication quality information included in the latest sensor information from the sensor 11K is at a low level. When indicating LQI, it is determined that the communication quality between the sensor 11K and its own sensor management device 12 is poor.

Then, the processing unit 22 creates the display information W based on its own judgment result, and outputs the created display information W to the display control unit 23.

When the processing unit 22 determines that the communication quality between the sensor 11K and the sensor management device 12 is poor, the display control unit 23 controls to display a screen indicating that the communication quality is poor as a cause of the inability to receive the sensor 11.

If not, and the communication quality information included in the sensor information does not indicate that the LQI level is low, it is determined that the sensor 11K is out of order.

Then, the processing unit 22 creates the display information U based on its own judgment result, and outputs the created display information U to the display control unit 23.

The display control unit 23 controls, for example, to display on the screen that the sensor 11K has failed as a cause of the inability to receive the sensor 11. Specifically, for example, the display control unit 23 transmits the display information U received from the processing unit 22 to the display 13.

On the display 13, for example, a screen different from the screen Pi3 shown in FIG. 3 in the following points is displayed. That is, on the screen, the non-receivable sensor list displayed in the list display area Gd indicates that the sensor 11K is out of order as the non-receivable cause.

When the processing unit 22 determines that the sensor information from the sensor 11K can no longer be received, the processing unit 22 indicates that the battery information included in the latest sensor information from the sensor 11K has a low remaining charge. If the communication quality information included in the sensor information does not indicate that the LQI level is low, it may be determined that the cause of the inability to receive the sensor 11K is unknown.

In this case, the display control unit 23 controls to display on the screen that the cause of the inability to receive the sensor 11 is unknown, instead of the fact that the sensor 11K is out of order, as the cause of the inability to receive the sensor 11.

When the user performs an operation to turn off the power of the sensor 11K, the sensor 11 outputs the operation stop information including its own ID and the off information indicating that the power is turned off before stopping the operation. It is created, and the created operation stop information is transmitted to the wireless communication device 14.

For example, the receiving unit 21 receives the operation stop information from the sensor 11 via the wireless communication device 14, and outputs the received operation stop information to the processing unit 22.

When the operation stop information is received by the receiving unit 21, the display control unit 23 controls to display a screen indicating that the power of the sensor 11 has been turned off as a cause of non-reception.

Specifically, when the processing unit 22 receives the operation stop information from the sensor 11K from the receiving unit 21, the receiving unit 21 cannot receive the sensor information from the sensor 11K because the power of the sensor 11K is turned off. recognize.

Then, the processing unit 22 creates the display information N indicating the display content of the display 13, and transmits the created display information N to the display control unit 23. The display control unit 23 transmits the display information N received from the processing unit 22 to the display 13.

On the display 13, for example, a screen different from the screen Pi3 shown in FIG. 3 in the following points is displayed. That is, on the screen, the unreceivable sensor list displayed in the list display area Gd displays that the power of the sensor 11K has been turned off as the cause of the unreceivable reception of the sensor 11K.

For example, when the screen Pi3 shown in FIG. 3 is displayed on the display 13, the processing unit 22 receives the sensor information from the sensor 11K from the receiving unit 21, and the receiving unit 21 receives the sensor information from the sensor 11K again. Judge that it is possible to receive.

Then, the processing unit 22 creates the display information P based on the content of its own judgment, and outputs the created display information P to the display control unit 23.

The display control unit 23 controls to return the display contents of the screen related to the sensor 11 that the receiving unit 21 can receive the sensor information to before the change. Specifically, the display control unit 23 transmits the display information P received from the processing unit 22 to the display 13.
