Description

TECHNICAL FIELD The present invention relates to a monitoring and control device, and more particularly to a device for monitoring and controlling the operation of a remote terminal device, such as an information board, in a road display system or the like.

(Background of the Invention) In a road display system, each terminal information board installed at an appropriate point on a roadway or highway is remotely controlled by a monitoring and control device in a control center. Generally, a terminal control device that directly or locally controls each information board is placed at an interchange or the like, and each terminal control device and the supervisory control device are connected through a public corporation line. Therefore, it usually takes several tens of seconds at the earliest until the supervisory control device starts display control, collation control, etc. on the information board, and in response, the information board operates and a supervisory signal is sent back. In particular, in the case of subtitle roll-up information boards, the operating speed is relatively slow, so it may take several minutes. During this time, the operator does not know the operating status.
I'm concerned. On the other hand, conventionally known devices have been known to turn on or flicker a predetermined display lamp during such waiting time, but the specific operating conditions are unknown and the problem remains unresolved.

(Object of the Invention) The present invention has been made in view of the above-mentioned problems, and it is possible to monitor and control a terminal device in a remote location, such as a device that monitors and controls an information board, by specifically monitoring the current operating status during the waiting time for monitoring and control. Based on the concept of displaying information, the aim is to eliminate operator anxiety and improve operational convenience.

(Structure of the Invention) In order to achieve the above object, the present invention is characterized by providing means for displaying the current operating status in text during the waiting time of supervisory control. According to a preferred embodiment of the present invention, means are provided for making the sentence display blink, thereby visually distinguishing it from the displays of other sentence display means.

(Description of Embodiments) The present invention will be described in detail below with reference to the drawings. Fig. 1 shows a monitoring and control device for a road display system to which the present invention is applied. In Figure 1, the supervisory control device or panel 1
An information board number display 2, a monitor display 3, and an alarm display 4 are arranged in the center of the vehicle.

The number displays 2A, 2B, and 2C display the device number of the terminal information board selected for status monitoring, and the corresponding monitor displays 3A, 3B, and 3C on the right side display the information currently output from those information boards. The content or information text is displayed respectively. The number of the terminal information board selected for display setting is displayed on the number display 2D, and the display content or information text to be output to the information board is displayed on the corresponding monitor display 3D on the right side. In this embodiment, the monitor display 3D is used to perform a sentence display function during the monitoring control waiting time, which will be described later. The alarm display 4 is arranged with display lamps indicating busy status, power outage, failure, display element abnormality, etc. At the top of the supervisory control panel 1, a group of lamps 5 for displaying the output status of each information board, a clock display section 6, and a supervisory control panel operating state display section 7 are arranged, and at the bottom, a time adjustment and regular monitoring time setting section 8 is arranged. Also provided are a group of push buttons 9 for monitoring the displayed content, stopping the buzzer, and running the Ranzo test.

Monitor displays 3A to 3 used in this type of monitoring control panel
D is generally a plasma display/e-channel or liquid crystal panel, the display capacity or maximum number of characters being displayed is usually 10 to 15 characters long per 1/l' panel.

FIG. 2 shows the display function during the monitoring control waiting time according to this embodiment. Number display 2A, 2B.

The information boards with device numbers 1', 2, and 3 are designated as 2C, and the information sentences currently output and displayed on those information boards are displayed on the corresponding monitor displays 3A, 3B, and 3C.

The number display 3D indicates the device number 4 of the information board currently under monitoring control, and the corresponding monitor display 3D shows the current operating status of the information board as ``Currently under display control'' and flickers or blinks. This state is shown by dotted lines in Figure 2. If the current operating state is in verification, the message "Currently in verification" will appear on the monitor display 3D. appears flickering.

When the monitoring signal is returned from the information board, such flicker display is erased and the currently outputted information text is displayed on the monitor display 3D instead. The display function described above allows the operator to see at a glance the operating status of the information board during monitoring and control. Furthermore, since the display is displayed in a flickering manner, it is easy to visually distinguish the display from the displays on the other monitor displays 3A, 3B, and 3C.

FIG. 3 shows in block form a control device for performing the display function during the above-described monitoring control waiting time. In FIG. 3, a control unit 10 including a CPU controls the operation of a character generator 111 and display controllers 12A to 120, and also controls each information board 1 via a public corporation line 13 and a terminal control device 14.
Connect with 5. When you indicate the device number of the desired information board on the number displays 2'A, 2B, and 2C (Figure 1 or Figure 2)
, a predetermined control signal is given to the character generator 11 from the control unit 10, and the data representing the information/sentences currently being output to these information boards is sent to the corresponding display controller 12A.

Sent to 12B and 12C. Each controller drives a specific pixel of the monitor display according to the information text data to display the information text.The controller specifies the device number of the information board 15 to be displayed on the L number display 2D to display the information text, and sets display contents or information. When displaying a sentence on the monitor display 2D, data representing the setting information sentence is sent from the character generator 11 to the display controller 12D in accordance with a control signal from the control unit 10.
sent to. When the display control is activated and a control signal instructing the setting information text is sent from the control section 10 to the display board 15 side, a waiting time begins. At this time, a predetermined control signal is given from the control section 10 to the character generator 11, and the above-mentioned information sentence "°
The data indicating "Currently under display control" is sent to the character generator 11.
The data is sent to the display controller 12D. At the same time, a signal instructing the display controller 12D to perform a blinking display is given from the control unit 10. As a result, the display controller 12
D drives a specific pixel of the monitor display 3D to blink in accordance with the information text data. When the monitoring signal is returned from the idle board 15, a predetermined control signal is given from the control section 10 to the display controller 12D, and the blinking drive is ended. Next, the information text currently or newly output on the display board 15 is displayed on the monitor display 3D.

Note that data representing the current operating status of the information board is sent from the terminal side to the control unit 10 as necessary until the monitoring signal is returned, and the current operating status is displayed blinking on the monitor display 3D each time. Good too.

Furthermore, the device configuration shown in FIG. 3 is merely an example, and various device configurations or circuits that perform similar functional operations are possible. Furthermore, as is easily understood, the present invention is also applicable to monitoring and control devices other than road display systems.

(Effects of the Invention) As described above, the present invention is capable of displaying the current operating status in a concrete and easy-to-understand manner during the waiting time for monitoring and control in a device that monitors and controls a terminal device located in a remote location, such as an information board. This provides operational and psychological convenience for the operator.
