DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A monitoring device and a monitoring method according to an embodiment of the present invention will be described below with reference to the drawings. FIG.
1 shows a functional configuration of a monitoring device including a display burn-in reducing device according to an embodiment of the present invention. As shown in FIG. 1, a monitoring device according to the present embodiment includes an input device 4 for inputting a monitoring command by an operation of a monitoring person, and a monitoring device main body 2 for controlling monitoring information from a monitored device 1 for monitoring traffic volume. And a display 3 for displaying monitoring information controlled by the monitoring device main body 2.

The monitoring device body 2 includes a monitoring information receiving unit 21 for receiving monitoring information from the monitored device 1 and a monitoring device for comparing the received monitoring information with the previous monitoring information stored in the monitoring information table 26 in advance. An information comparison unit 24, a color component control unit 23 that controls the color components of the monitoring information displayed on the display 3 based on the comparison result in accordance with the importance, and a monitor controlled by an instruction from the color component control unit 23. It comprises a display unit 22 for displaying information on the display 3 and an input device monitoring unit 25 for monitoring a monitoring command from the input device 4.

The color component control unit 23 includes a monitoring information processing unit 231 for determining a color component of a monitoring value of the monitoring information from the monitoring information comparing unit 24 as a highlighting component, and an input device monitoring unit 2.
5 is configured by a burn-in reduction command processing unit 232 that controls the color components of the monitoring information in accordance with the degree of importance according to the command from No. 5.

Next, the operation of the monitoring device provided with the display burn-in reducing device will be described. In the description, a traffic volume representing the number of vehicles passing per unit time on a road is taken as an example. FIG.
2 shows a flowchart of the overall processing operation of a monitoring device provided with the display burn-in reducing device of FIG. As shown in FIG. 2, first, in step 101, the monitoring information receiving unit 21
Receives the identification number and the traffic volume of the monitored device from the monitored device 1 that monitors the traffic volume, and sends it to the monitoring information comparison unit.

Next, the monitoring information comparison unit 24 compares the received traffic volume with the traffic volume currently displayed on the display 3 from the monitoring information table 26. If the traffic volume values are different, the received traffic volume is compared with the received traffic volume. The amount and the identification number of the monitored device 1 are sent to the color component control unit 23.

On the other hand, the input device monitoring unit 25
Is monitored by a timer. When a predetermined time has elapsed without the input device 4 being operated by the monitor, a burn-in reduction display command is sent to the color component control unit 23. When the input device 4 is operated after sending this command, a command to cancel the burn-in reduction display is sent (102).

Next, the monitoring information table 26 stores the identification number of the monitored device currently displayed on the display 3 and the traffic volume thereof. If the traffic volume differs as a result of the comparison, The traffic volume in this table is also rewritten (103).

Next, the monitoring information processing section 231 determines a color component from the identification number of the monitored device and the traffic volume sent from the monitoring information processing section 24 (104).

The color components and display contents (display position and traffic volume on the display) are sent to the display unit 22. When the burn-in reduction command processing unit 232 receives the burn-in reduction display command from the input device monitoring unit 25, the display items other than the traffic amount among the display items displayed on the display and the values having the low importance (unit) are displayed. (The number of vehicles passing by time is small), the display content to be redisplayed with the color components lowered is sent to the display unit 22. When receiving the burn-in reduction display canceling command, the display unit 22 sends display contents to be displayed with the normal color components for all display items (105).

The display unit 22 displays on the display 3 in accordance with a command from the color component control unit 23. (106) FIG. 3 shows a flowchart of the processing operation of the monitoring information comparison unit 24 in FIG. As shown in FIG. 3, first, when the identification number and the traffic volume of the monitored device 1 are received as monitoring information from the monitoring information receiving unit 21 in step 201, the information of the monitored device 1 already received from the identification number is received. It is determined whether or not.

Next, when the information of the monitored device 1 is the first, the traffic amount is stored in the monitoring information table 26, and the identification number and the traffic amount are sent to the color component control unit 23 (202).

In the case of the information of the monitored device 1 that has already been received, the current display 3
Is retrieved (203). The retrieved traffic volume is compared with the traffic volume of the received monitored information (204).

As a result of the comparison, if they are the same, the process exits the processing of the monitoring information comparison unit 24 (205). If not, the traffic volume of the monitored device 1 in the monitoring information table 26 is rewritten (206).

After rewriting the monitoring information table 26,
The identification number and traffic volume of the monitored device 1 are sent to the color component control unit 23 as the received monitoring information. (207) FIG. 4 shows a flowchart of the processing operation of the color component control unit 23 of FIG. As shown in FIG.
In step 1, the monitoring information processing unit 231 checks whether monitoring information has been sent from the monitoring information comparison unit 24.

When the monitoring information has been sent, the color component to be displayed is determined from the identification number of the monitored device 1 in the monitoring information and the traffic amount. The display position on the display is determined from the identification number of the monitored device 1. The traffic amount displayed together with these pieces of information is sent to the display unit 22 as display contents (302).

Next, it is checked whether an instruction has been sent from the input device monitoring unit 25. If there is no command, the process of the color component control unit 23 ends (303).

If an instruction has been sent, it is checked whether or not the instruction is a burn-in reduction display instruction (30).
4). In the case of the burn-in reduction display command, it is checked whether the burn-in reduction display state is already present (305).

When the display is not in the burn-in reduction display state, the position and color component on the display other than the value of the monitored device 1 on the display are determined and sent to the display unit 22 as display contents. . At this time, it is assumed that the color components of these display items are uniformly reduced by a certain ratio from the values of the normal color components (307).

When the burn-in reduction display state or the display item other than the value of the monitored device 1 is lowered and displayed, the loop is repeated by the number of monitored devices displayed on the display (308).

In this loop, first, the monitored device 1
It is checked whether the value of is high (309). If the importance is high, the color component and the display position on the display are determined from the type and position of the monitored device 1 and sent to the display unit 22 together with the value. The color component at this time is normal (31
1).

If the importance is not high, the color component is set to a value lower than usual, and the display position on the display and the value of the monitored device are sent to the display unit 22 (310).

If the command from the input device monitoring unit 25 is a burn-in reduction display canceling command, the display unit 22 displays the display contents of the normal color components for all display items including the value of the monitored device. To cancel the burn-in reduction display. (306) FIG. 5 and FIG. 6 show display examples of traffic volume on a specific display. The importance can be set arbitrarily, but in this example, a value of “50” or more is set as a high importance. As shown in FIG. 5, (a) shows a display using normal color components. (B) is a display example in which the input device 4 has not been operated for a certain time and the color component of the display item has been reduced to be in the burn-in reduced display state. At this time, the display of "80 units" having high importance remains the normal color component.

FIG. 7C is a display example when the value of the monitored device changes in the burn-in reduction display state. That is, (b)
The value of the monitored device in “30” is changed to “40” and “40”
When the “unit” is changed to “80 units”, the value of the monitored device is displayed in a normal color component in which the color component is raised from a display in which the color component is lowered.

(D) shows the state of the input device 4 in this state.
Is not operated for a certain period of time. In the display of the monitored device whose value has changed in FIG.
The display of "40" which does not reach "0" is displayed with a color component lower than usual.

(E) is an example in which the input device 4 is operated in the burn-in display state, in which all display items displayed on the display 3 are displayed in normal color components.

[0038]

According to the present invention, the burn-in of the display can be reduced, and the change of the value of the monitoring device displayed on the display and the information of the arbitrarily set importance can be visually highlighted. Oversight of the information by the supervisor (operator) can be reduced, and the monitoring accuracy can be improved.
