Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio status display for simultaneously displaying a radio status on a data display device when radio is used as a means for transmitting data from a data transmission source device to a data display device. The present invention relates to a method and a data display device.

[0002]

2. Description of the Related Art When data is transmitted wirelessly, if the condition of the wireless communication deteriorates, the data becomes an error, and the reliability of the data decreases. Therefore, the user of the data display device needs to know the wireless state in order to determine the reliability of the displayed data while looking at the data display unit.

Conventionally, a wireless status is displayed by a character 5 on a data display section 4 of a data display device 2 as shown in FIG. 5, a symbol 6 is displayed as shown in FIG. 6, or a lamp as shown in FIG. 7
To display. In the case of the lamp display 7, when the lamp is turned on, the wireless state is good, and when the lamp is turned off, it is defective. In the case of the symbol display 6, the intensity of the radio wave is represented according to the number and size of the symbols.

[0004]

However, in the above-mentioned conventional display methods, any of them is difficult to understand, and the user cannot accurately recognize the radio condition. Therefore, it has not been sufficient to determine the reliability in data transmission requiring high reliability.

SUMMARY OF THE INVENTION An object of the present invention is to provide a radio status display method capable of resolving the ambiguity of the conventional radio status recognition and easily and accurately judging the radio status.

[0006]

The above object is achieved by providing means for displaying the status of the wireless portion in color on the data display portion of the data display device.

In the above color display, when the background color of the entire data display section is changed according to the radio condition,
When displaying color in a part of the data display unit according to the wireless status, when blinking the display color of the data display unit according to the wireless status, the color of the data display displayed on the data display unit according to the wireless status It may be displayed differently.

Further, the above object is achieved by providing means for displaying the state of the wireless portion numerically in the data display portion of the data display device.

In the numerical display, the number of error packets is obtained from the number of transmitted packets and the number of received packets, and the packet error rate is calculated and displayed. In the case of numerical display in a stepwise manner, there is a case where the throughput is calculated from the total number of transmitted / received packets and displayed.

As described above, since the state of the color or the numerical value is displayed, the user can easily confirm it in detail. Therefore, the user can always recognize the reliability of the data displayed on the data display unit.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, showing a case where data is transmitted from a data transmission source device 1 to a data display device 2 by using a radio 3. A part 8 for determining the wireless state by means for checking the wireless state is provided in the data display device 2, and the result determined by the determination unit 8 is displayed on the display unit 4 of the data display device 2 or as shown in FIG. Displayed in the unit 9.

Means for checking the wireless status of the wireless status determination unit 8 include, for example, determining the electric field strength level, managing the serial number of data, determining based on the number of missing data, bit error rate of data, Judgment is made based on the packet error rate when transmitting and receiving packets.

As a method of displaying the judgment result, the state is displayed in color on the data display unit 4 capable of displaying color by the following method.

(1) The background of the entire data display section 4 is displayed in color. For example, the wireless state is divided into three stages (good, average, and bad), and good = green, average = yellow, and bad = red.

(2) The color of the background is changed only when the data becomes defective below the level at which the reliability of the data is impaired. For example, the normal display is blue, and if defective, it is red.

(3) The above items (1) and (2) are displayed not on the entire screen of the data display section 4 but on a part 9 thereof.

(4) When the display of (1) to (3) above is particularly emphasized, the screen is blinked. For example, the display of red and blue is switched at regular intervals and displayed.

(5) The data displayed on the data display section 4 is displayed in different colors such as characters and symbols.

According to the above-described color display method, since the wireless status is displayed in color, it is easy for the user to understand, and the user can always recognize the reliability of the displayed data.

FIG. 3 shows an embodiment in which, as means for confirming the state of the transmission data of the radio state determination unit 8, a determination is made based on a packet error rate when data packets are transmitted and received. The transmission packet 11 is wirelessly transmitted with a packet number added thereto. The data display device 2 receives packets (received packets 12) and manages their serial numbers. The wireless status is displayed numerically on a part 9 of the data display unit 4 in the following manner.

(6) The number of error packets is determined from the number of transmission packets 11 and the number of reception packets 12. In FIG. 3, the packet “3” is a transmission error, the total number of transmitted packets is 5, the total number of received packets is 4, and the error is 1. Therefore, the packet error rate = 1 ÷ 5 = 0.2 is calculated, and “0.2” is displayed on the display portion 9.

(7) The total number of transmitted packets 11 and the total number of received packets 12 are displayed on the display section 9. For example,
By (6), the total number of transmitted packets 5 is grasped and displayed together with the total number of received packets 4.

(8) Display the electric field strength. For example, the electric field intensity is numerically displayed in 100 steps.

(9) Display the throughput. For example, the transmission throughput is calculated and displayed from the total number of transmitted / received packets obtained in (7).

FIG. 4 shows a stock price notification system according to an applied embodiment of the present invention.
The stock price information is transmitted through. The data transmission device 1 transmits the received stock price data to the data display device 2 by wireless transmission 3.
To be transmitted. In this case, the state of the wireless device 3 is displayed by color display or numerical values according to the above method, and the user can always recognize the reliability of the data displayed on the data display unit 4.

[0027]

As described above, according to the present invention, it is possible to easily and in detail check the radio condition. As a result, the user can accurately determine whether the reliability of the data displayed on the data display device is high or low, and the operational reliability of the device is improved.
