Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a remote monitoring device that automatically responds to incoming calls and receives data as a receiving device for a terminal device connected via an automatic station subscriber line. It is something.

[Prior art]

This type of device is placed at a security insurance company, etc. as a center device for terminal devices, such as emergency call devices, and identifies received data. In order to be able to take corrective action, it is common to have a display unit that displays received data in the order in which it is received, in addition to a printer or the like. This display section is composed of, for example, a light emitting diode, and if new data is received, it will shift to displaying new data one by one, but if necessary, it will be able to perform a hold operation and will not erase specific display data. You can also keep it on hold.

By the way, the display section of such received data is
Partly because displays are expensive, their display capacity is usually limited to a few items. For this reason, when all display data is put on hold, such as when a large number of incoming calls are received in succession, subsequent received data is only output to the printer and cannot be immediately known from the display.

[Object and structure of the invention]

The present invention has been made in view of the above circumstances, and an object thereof is to provide a received data display method in a remote monitoring device that allows all received data to be displayed on a display unit.

In order to achieve such an objective, the present invention
a hold display means for instructing a hold display state for each display data, which prohibits clearing of the display data; a memory for separately storing a plurality of pieces of received data in the order of reception when all the display data of the display unit is in the hold state;
The apparatus is equipped with a control means for automatically canceling the suspension of the oldest display data and displaying the shift display when the memory becomes full, and displaying the oldest stored data. Hereinafter, the present invention will be explained in detail using Examples.

〔Example〕

FIG. 1 is a block diagram showing one embodiment of the present invention. As shown in Figure 2, this remote monitoring device is connected to each emergency notification device 21 via an automatic station connection line, automatically responds when it receives an incoming call, identifies the data consisting of the received multi-frequency signal, and Display and print out the contents.

That is, in FIG. 1, the remote monitoring device main body 1 is connected to the office line L in parallel with the main telephone TEL, but when necessary such as during a test, it can be disconnected from the main telephone TEL by the disconnector 2. I'm getting ready to let go. In this embodiment, the maximum number of station lines that can be accommodated is four lines. 3 is a station line circuit and network control unit that detects an incoming signal, captures the line, and releases it again after receiving data; 4 is a main control unit equipped with a CPU; all operations of this remote monitoring device are performed by this main control unit. It is controlled by a control signal sent from 4. Reference numeral 5 denotes a display section consisting of a light emitting diode, etc., 6 an operation section consisting of a keyboard, 7 a printer section, and 8 a built-in memory which will be described later. Further, 9 is an external display device, 10
is a data aggregation device that displays the status of all connected emergency notification devices and aggregates data.

Note that 11 is a power supply section, 12 is an emergency power supply unit, and 13 is a line protection device. Further, in FIG. 2, 22 represents a telephone office, 23 represents a sensor, and 24 represents a line protection device.

Here, the data received from the emergency notification device is multi-frequency signal data configured as shown in Figure 3, and the functional data includes 8 types of abnormal data corresponding to the operation of various sensors, warning data, There are a total of 11 types of release data and test data, and when data including these functional data is received, they are sequentially displayed on the display unit 5.

FIG. 4 shows the configuration of the display section 5. In the figure, the numbers at the left end of the panel 41 indicate the order of reception, and the received data is displayed in the order of reception, starting from the first line and continuing to the second, third, and fourth lines. That is, in each row, the first display section _D1 is a section that displays a three-digit number indicating the subscriber address, and the second display section D1 is a section that displays a three-digit number indicating the subscriber address.
A number indicating the functional data is displayed on D ₂ . On the other hand, the fifth to eighth display sections D ₅ to _{D 8} are for making it easier to understand the types of abnormal data, and the fifth to seventh display sections D ₅ to D ₇ are used to display the main abnormal data, For example, emergency, fire, and intrusion data are assigned to each, and the eighth display section _D8 is assigned to other abnormal data, and lights up when each data is received. Therefore, the second display section
There is no need to translate the D ₂ numbers. Similarly, the third display section _D3 and the fourth display section _D4 are sections that display warning data and release data, respectively.

Further, OL is an overflow lamp indicating an overflow of the memory 8, as will be described later.

As mentioned above, when there is reception from the emergency notification device, the display is performed sequentially from the first line, and when new data is received after all four lines are displayed,
The display on the first line disappears, the display on the second and subsequent lines shifts to the upper line, and new data is displayed on the fourth line, but if you do not want to erase the displayed data, press the operation panel. By operating a predetermined key provided at 6, display of the corresponding line can be suspended.

When new data is received while all four lines of display data are pending, that data is immediately transferred to the memory 8.
is stored in The memory 8 has a capacity to store up to 20 items of received data, and the received data are sequentially accumulated in the memory area of the memory 8 unless the display data is released from the pending state.

All 4 lines of display data are on hold and memory 8
When the data is stored in the entire memory area, the main control unit 4 sends a control signal to the overflow lamp OL to cause it to blink.

When an incoming call is received in this state, the oldest display, that is, the first line, is automatically released from hold, the second and subsequent lines are shifted to the upper line, and the fourth line is stored in the memory 8. The oldest received data is displayed, and the stored data in the memory 8 is also shifted, and the latest received data is sequentially stored in the empty memory area.

All of the data received in this way was sequentially displayed on the display section 5. When the memory 8 becomes full, the hold on the oldest display data will be automatically released, but in that case, when the memory 8 becomes full, the overflow lamp OL will blink to issue a warning in advance. Therefore, pending data will not disappear without the operator's knowledge.
Of course, this warning may be provided by an alarm sound, and it goes without saying that the warning will be even more reliable if both are used together.

If the control operation of the main control section 4 described above is shown in a flowchart, it will be as shown in steps 100 to 108 in FIG.

The above description has been made using a remote monitoring device connected to an emergency reporting device as an example, but the present invention is not limited to this, and can be used as a receiving device for various terminal devices that send data via an automatic station connection line. Needless to say, the present invention is generally applicable to remote monitoring devices.

〔Effect of the invention〕

As explained above, according to the present invention, there is provided a hold display means for instructing a hold display state for each display data, which prohibits the clearing of the display data, and a hold display means for instructing a hold display state for each display data, and a hold display means for instructing a hold display state for each display data, and a hold display means for instructing a hold display state in which clearing of display data is prohibited, and a hold display means for instructing a hold display state for each display data, and a hold display means for instructing a hold display state for each display data, and a hold display means for instructing a hold display state in which display data is prohibited from being cleared, and a hold display means for instructing a hold display state for each display data. It is equipped with a memory for separately storing a plurality of items in the order of reception, and a control means for automatically canceling the hold on the oldest display data and displaying it in a shifted manner when this memory becomes full, and displaying the oldest stored data. Therefore, all received data can be checked on the display unit.
