Abstract

PURPOSE:To easily separate data from a general message by once storing successively polled results in the tables of plural stations to be polled with data receivers and outputting the data after finishing whole polling. CONSTITUTION:A receiving means 1 to be controlled by a control means 5 is equipped with a polling table 4 for the plural stations to be polled. At fixed time or as needed, the control means 5 sends out a polling signal from the polling table 4 through a polling means 3 to the plural stations to be polled. When the polling signal is detected, the station to be polled returns the information of a state determined in advance to the receiving means 1. The receiving means 1 once stored the received information in a data memory 6. When detecting the polling completion of all the stations to be polled, the control means 5 reads out the data of the data memory 6 and outputs them from a data output means 2. Thus, from a received message, the general message and a polling message are easily distinguished and separated.

[Industrial application field]

The present invention relates to a data receiving device having a polling function and a received data output function.

In recent years, some facsimile machines have a fixed polling function that collects fixed-format messages such as daily reports and sales tables from a large number of slave stations such as branch offices to a center at fixed times. In a center device having such a facsimile device, it is required to make the office work of processing received output messages more efficient.

[Prior Art and Problems to be Solved by the Invention] In a facsimile machine having a scheduled polling function that collects fixed messages such as daily reports and sales tables from multiple slave stations at a fixed time, it is possible to Referring to the polling table in which the station numbers of slave stations are restored, a polling signal is sent to each of the nuclear layers in turn, and the data sent in response to the polling signal is received, decoded, and output. do.

Although the facsimile machine described above can receive general messages regardless of polling, conventionally,
Each time data is received, it is decoded and output, regardless of whether it is data received from each slave station using the scheduled polling function or general telegrams received regardless of polling.

Therefore, during scheduled polling, before polling for all slave stations on the polling table ends,
When data such as a general message is received, the data of the general message is output following the data up to the slave station in the middle of scheduled polling, and when the output of the data of the general message is finished, the data of the general message is output to the remaining slave stations. Regular polling is performed, and received data from them is output. Regular polling as described above is generally performed late at night, etc.
A facsimile machine that decodes and outputs data as described above each time it receives data may receive data during scheduled polling in a standard message containing daily reports, sales tables, etc. from a large number of branches, sales offices, etc. Since the output is stacked with general messages mixed in, the task of sorting the received messages becomes extremely complicated, and this poses a problem in that it impedes office efficiency.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a data receiving device that improves the efficiency of sorting received messages of regular polling and general messages.

[Means to solve the problem]

FIG. 1 is a basic configuration diagram of the present invention.

In FIG. 1, 1 is a receiving means, 2 is a data outputting means,
3 is a polling means, 4 is a polling table, 5 is a control means, and 6 is a data memory.

The receiving means 1 receives the message. Data output means 2 outputs data.

The polling means 3 outputs a polling signal to a designated other station and receives response data.

The polling table 4 stores the numbers of a plurality of partner stations that perform the polling.

The control means 5 includes the receiving means 1 and the data outputting means 2.
, the polling means 3 and the polling table 4.

Data memory 6 holds data.

The polling table 4 has an end flag indicating whether polling for each of the plurality of partner stations has been completed, and the control means 5 refers to the polling table 4 to perform polling for each of the plurality of partner stations. The data received through polling is temporarily held in the data memory 6, and completion flags for all of the plurality of partner stations are monitored to detect that polling for all of the partner stations has been completed. Then, the data held in the data memory 6 and received from all of the plurality of partner stations are sequentially outputted by the data output means 2.

[Effect]

The control means 5 sequentially polls a plurality of partner stations with reference to the polling table 4, temporarily stores each data received by the polling in a data memory 6, and sets an end flag for all of the plurality of partner stations. When it is monitored and it is detected that polling for all the partner stations has been completed, the data received from all the plurality of partner stations held in the data memory 6 is transferred to the data output means 2.
Outputs sequentially. Therefore, even if a general message is received before polling of all partner stations is completed while sequentially polling a plurality of partner stations with reference to the polling table 4, 1. The output of this general message will no longer be mixed in with the output of regular polling.

〔Example〕

FIG. 2 shows the configuration of a facsimile machine as an embodiment of the present invention.

In FIG. 2, 11 is a main control unit, 12 is a data memory, 13 is a communication control unit, 14 is a modem, 15 is an NCU, 1
6 is a restoring unit, 17 is a recording unit, 18 is a regular polling destination table, and 19 is a previous destination end detection unit.

The facsimile machine shown in FIG. 2 operates under the control of a main control section 11 having an MPU, including a communication control section 13, a modem 14,
The transmission data is output to the line via the NCU 15 and the NCU 15, and the data transmitted on the line is output to the NCU 15.
It is received via the modem 14 and the communication control unit 13.

Normally, when a general message is received, immediately after receiving the data, the restoration unit 16 performs an error check, and the data in the form of a run-length signal is restored to bitmap data, and the recording unit 17 converts the data into bitmap data. Print and output map data.

The scheduled polling destination table 18 is provided to implement the above-mentioned scheduled polling function, and for example, as shown in FIG. Contains an end flag indicating whether or not the process has been completed.

At a predetermined time every day, the main control section 11 refers to the above-mentioned scheduled polling destination table 18 and reads out the telephone numbers of the destinations whose end flags indicate that polling has not been completed one by one. 13, modem 14, and N
A polling signal is output on the line via the CU 15.

Then, the data sent from the destination is sent to the NCU1.
5, the modem 14 and the communication control unit 13.

The procedure for polling reception in scheduled polling processing is as follows:
It is shown in FIG.

That is, when response data to one polling is received at step 21 in FIG. When there is no error, this data is retained in the data memory 12 in its original data form. If there is an error in the data, the receiver issues a retransmission request to the transmitter to retransmit the data.

When the completion of data reception from the above one destination is confirmed in step 22, the scheduled polling destination table 18
The end flag of the destination to which the above polling was performed is set to ○N to indicate the end. Then, in step 24, the states of the end flags of all destinations in the scheduled polling destination table 18 are monitored to detect whether polling for all destinations has ended. Although this detection function is shown in FIG. 2 as the all-destination end detection unit 19, it is actually realized as a flag monitoring function by software as described above.

In step 24, if polling has not been completed for all destinations, polling is sent to the next unfinished destination, and steps 21 to 24 in FIG.
Repeat the process.

In step 24, the port+IJ for all destinations is
When the end of the song is detected, in step 25, the received data from all the destinations held in the data memory 12 is sequentially read out, restored by the restoring section 16, and printed out by the recording section 17. Output.

With the above procedure, even if a general message is received during the above-mentioned scheduled polling, the general message will be printed and output as it is at the time of reception, and then the end of polling for all destinations will be detected. When this happens, all the data received through regular polling is printed and outputted at once. Therefore, general telegrams will not be mixed in between the printouts of regular polling, and the sorting of recorded outputs will no longer complicate the work and impede the efficiency of office processing.

The present invention has the effect of significantly improving office processing efficiency, particularly in a system that sequentially receives fixed-format messages from a large number of polling destinations, such as a credit card company with a nationwide branch network, through regular polling.

〔Effect of the invention〕

According to the data output device of the present invention, it is possible to improve the efficiency of sorting received telegrams and general telegrams for regular polling.
