Abstract

PURPOSE:To perform display of numbers of error check and clarification of good or not of circuit condition by counting a discrimination signal of data errors through error check function, and by displaying error count value by output at proper time. CONSTITUTION:In case transmission of data starts and transmission process is conducted, the discrimination of transmission error is performed based on the function of check. When the transmission error is repeated many times, 1 is added in order to successive error count value, and when exceeding the set retry-count value, a circuit cut-off process is carried out. In terms of display ion process of error count and retry count, when an error count display key of a KEY 12 is pushed, an error count value and retry count value stored on count in memory are outputted to a display device 14 through an I/O device 8. The display device 14 outputs to LED display device displaying lower three figures as error count value and middle two figures as retry count value.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone equipped with a display device that displays the number of transfers when a transfer error occurs during data transfer using a telephone line P-ROM writer, for example. Line P- relates to the ROM writer.

<Prior art> Recently, a telephone line was connected to the P-R/αM writer, and the
-By transferring the ROM data over the phone, the P-', R:QJ writer installed at a remote location can be transferred to the P-R.
Telephone line P- that made it possible to write data to OM
ROM writers have been put into practical use.

However, data transmission over telephone lines has reliability problems, and data transmission errors often occur.

Therefore, in order to check for transfer errors and improve the reliability of transfer, telephone line P-ROM writers have been developed that are equipped with checking functions such as vertical parity check, horizontal parity check, and echo check.

<Problems to be Solved by the Invention> The present invention has been made in response to the above-mentioned current situation, and it is possible to improve the number of error checks for the telephone line P-ROM writer equipped with the above-mentioned transfer error checking function. To provide a telephone line P-ROM writer which has a function of displaying the number of errors so that it is possible to clearly know whether the line condition is good or bad.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the apparatus of the present invention.3 Referring to the same figure, a memo 'l-121 stores a transfer program, a transfer check program, a transfer error count processing program, etc. 121, the necessary data settings are made in advance from the outside, so the display device (
Reference numeral 141 is an LED which outputs and displays the number of errors and the like. The I10 device (8) is a P-ROM (
10+, KEY (121, display device (141, CPU
(It is provided between 1410 and 1410 and plays the role of a data input/output device. Also, the transfer device (6) uses an LSi tape to transfer data to the telephone line. The ROMfiO) is for data transfer, and the CPU+4+ performs processing and control based on data etc. in the memo 1.1-+2+. The same P7ROM writer is provided via the telephone line (2o) so that data of the P-ROM can be transferred.

Next, specific operations will be explained based on the broach yard shown in FIG.

First, P-ROM writer (301 side (7) P-ROM (
10+ data via telephone line (2o) P-R,
Consider the case where data is transferred and stored in the P-ROM (1B) on the OM writer Gυ side.

In this case, P-ROM(Intnode1';!i10
Under the control of the CPU +4+ based on the data in the memory (2), the transfer device (6)
where it is converted into a modem signal for the telephone line,
The data is transferred to the P-ROMC 31) side. P-ROM
When the writer Gυ receives this sent modem data, it converts it into a normal mode signal via the transfer device (6), passes through the i10 device (8), and sends it to P-"R ([1M
Data storage in the memory is also performed under the control of the CPU +4+ based on the data of the memory IJ-(2+). During this data transfer, horizontal parity check and vertical parity check are performed to prevent transfer errors. check,
In order to obtain a data check function such as an echo check, the program is stored in the memory (2) of each P-IL [M writer 00), C31). Therefore, at the time of transfer, the above-mentioned check will be carried out.

Here, for example, the P-ROM writer (3
If the data received in step 1) is subjected to such a check function and there is an error, an error signal is sent to the other party's P-ROM writer, and the same data is retransmitted. If there is an error in the data even after retransfer, the data will be retransferred again.
Enter it through 21.

As shown in FIG. 3, the KEYG 21 consists of number keys 0 to 90, a retry count set key, and an error count display key. Now, by pressing the 1, 1, 1, and 60 number keys with this retry count set key, the number 6 will be set to I10 as retry count data.
It is stored in the memory (2) via the device (8).

Now, when the data transfer is actually notified and the transfer process is performed, a "transfer error?" determination is made based on the above-mentioned check function. If a YES determination is made here, 1 is added to the continuous error count register.

In the next step, the count value of this continuous error count and the above-mentioned try count value are judged to be large or small. Initially, the continuous force 'runt value was 1 and the retry count was set to 6, so ζrNOJ was determined,
In the next step, further data transfer processing is performed,
The transfer is continued until the transfer is completed by the determination "Transfer completed?".

Next, 1 transfer error? In the judgment step of ``, if rNOJ, it means that there is no error, and the continuous error count value is set to O, and if the transfer ends as it is, rE
It becomes NDj.

Also, if a transfer error is repeated many times, 1 is added to the continuous error count value in sequence, and when the retry count value exceeds 6, a judgment of "retry count value - continuous error count value" is made and the result is "YES". ”, and it is assumed that there is no point in repeating the transfer any more, and line cutoff processing is executed, resulting in rEN DJ.

Also, "error count and retry count display processing"
is executed when the operator inserts the error count display key of KEY (121) mentioned above, and the error count value and retry count value stored in the memory are displayed via ■10 device (8). Output to the display device (141).

The display device α4 outputs a live count value to an LED display as shown in FIG. 4 (the last digit is the error count value and the middle two digits are ll).

It should be noted that the device of the present invention has the CPU
Create a program to start the clock timer in +41, store the program in Memo +1-+21, and output the transfer time to the display device using the procedure shown in Figure 5. This can lead to improved performance as a P-ROM writer.

<Effects of the Invention> The present invention is as described above, and produces the following excellent effects.

In other words, the telephone line P-K with the Erato Ezoku function
By providing an error count display device for the OM writer, when a line disconnection occurs, it can be determined whether it is due to poor line conditions or not.
- This can be useful in determining whether there was a mistake in the illumination code for the I-phase hand or a power outage.
