Description

  The present invention relates to a reception status display method in an FPU remote control system, which is a device for remotely monitoring and controlling a receiving base station which is a receiving facility of a transmission device (FPU).

Conventionally, in broadcasting stations that broadcast various programs, video materials (broadcast materials) that are used in broadcast news programs, etc. are captured by a television camera, etc., and the resulting video materials are relayed by microwaves, etc. The received radio wave is received by a receiving base station (for example, a receiving facility installed at a mountaintop with good visibility) and the received broadcast material is transmitted to the broadcast station via a dedicated TSL (Transmitter Studio Link) line. Then it is recorded or broadcast.
Here, in the case of a conventional analog FPU, the reception state of the receiving base station is displayed on the CRT of the operating terminal personal computer of the broadcasting station, for example, by a meter for indicating the strength of the received electric field, and the operator However, it was a method of judging the quality by looking at the display.
On the other hand, in a digital FPU used for a broadcasting system that has been developed in recent years as terrestrial digital broadcasting, it is not possible to accurately determine whether a reception state is good or not only with a meter that indicates the strength of a received electric field.

FIG. 4 is a diagram showing an example of an operation terminal display screen of an FPU remote control system related to the conventional technology. In this figure, reference numeral 101 denotes a display screen of an operation terminal personal computer of the FPU remote control system, which is a device for controlling and operating the power base / frequency of the turntable of the receiving base station and the receiver. Reference numeral 102 denotes a planar map display area near the receiving base station. Reference numeral 103 denotes a line indicating the direction of the rotating antenna of the receiving facility on the planar map display area 102 when true north is 0 degree, and 104 is a meter indicating the received electric field strength of the radio wave received by the rotating antenna of the receiving facility. For example, a plurality of LEDs are arranged side by side. Usually, the operator moves the rotating antenna while looking at the meter 104 and adjusts it in the direction in which the received electric field is strongest (see, for example, Patent Document 1).
Here, the display of the reception electric field meter in the conventional FPU remote control terminal has a specification that, as shown in FIG. 5, when the reception state is bad, the LED is turned off and turned on one by one from the left as it gets better.
JP 2000-341224 A

As described above, in the digital FPU, it is not possible to accurately determine whether the reception state is good or not only with a meter indicating the strength of the received electric field.
For example, in a digital FPU, even if the received electric field strength is strong, if the bit error rate (BER), which is an error occurrence rate per unit time, in the received signal is bad, reception is impossible, such as reception is impossible. Understanding the BER state is an important factor.
In order to eliminate these disadvantages, the present invention displays the BER status in addition to the reception electric field strength in the reception status display in the FPU remote control system, and reduces the operator's uncomfortable feeling caused by the difference in the display method. The purpose is to make it possible to instantaneously determine whether the reception state is good or bad.

  In order to achieve the above object, the present invention displays the reception state in the FPU remote control system by displaying the BER state on the operation terminal display screen of the FPU remote control system in addition to the display of the reception field strength, and the reception field strength. Is a reception status display method of the FPU remote control system that displays the BER status and the BER status on the same display standard.

  As described above, according to the present invention, the reception field strength display and the BER state display criteria (conditions) are made the same, so that the operator can judge the reception field strength and the BER state with the same good / bad judgment criteria. Therefore, there is no possibility of causing confusion in the operation of the remote control terminal.

FIG. 1 shows an example of an operation terminal display screen of the FPU remote control system of the present invention, 11 is a display screen of an operation terminal personal computer of the FPU remote control system, 12 is a planar map display area near the receiving base station, and 13 is A line indicating the direction of the rotating antenna of the receiving facility on the planar map display area 12 when true north is 0 degree, 14 is a meter indicating the received electric field strength of the radio wave received by the rotating antenna of the receiving facility, and 15 is received. A meter representing a bit error rate (BER) state which is an error occurrence rate per unit time in a signal. For example, a plurality of LEDs are arranged side by side.
First, a specific display example of the meter 15 representing the BER state displayed on the display screen 11 of the operation terminal personal computer of the FPU remote control system together with the reception electric field meter 14 as shown in FIG. 5 will be described with reference to FIG. .
The meter representing the BER state is, for example, a plurality of LEDs arranged side by side, all turned on when the BER is in an adverse condition, and turned off from left to right as the good condition is reached.
When these reception electric field meters (FIG. 5) and the BER state meter (FIG. 3) are displayed side by side, the display criteria (direction in which the state deteriorates) are different, so that the operator is in good condition when the LED is lit. It is difficult to instantly determine whether this is a bad condition, which may cause confusion for the operator who operates the rotating antenna.

Therefore, in the present invention, as shown in FIG. 2, the display standard of the meter representing the BER state is made the same as the display standard of the reception electric field meter shown in FIG.
That is, the LED is turned off in a situation where the BER state is bad, and is turned on one by one from left to right as the situation becomes good.
Note that the numerical values in FIG. 2 are displayed by taking the power part from, for example, “10 ⁻⁴ ” of the BER value (error occurrence rate). In the squares representing the LEDs, the shaded areas (with colors) are turned on, and the white areas are turned off.
As described above, according to the present invention, the reception electric field meter and the BER state meter have the same display standard, that is, the right and wrong display directions are the same. Since the state is bad and it can be instantaneously determined that the reception state is improved as the LED is lit, the rotating antenna can be operated accurately.
