How to Adjust Send / Receive Status for Specific Regions in Fax Data Communication

The present invention relates to a method for adjusting a transmission / reception status for a specific area in a fax data communication. More particularly, the present invention relates to a transmission level and reception in a communication line state of a transmission / reception area when a fax or multifunction device transmits or receives a fax data. A method of automatically adjusting the sensitivity.

In general, a facsimile is an office automation device that performs fax data communication using a public telephone network. Recently, a facsimile is a terminal used independently of a facsimile such as a printer, a copier, and a scanner. Multifunction terminals called MFPs (Multi Function Peripharal) may be used.

In the conventional fax or multifunction fax data communication, the transmission level and reception sensitivity at the time of sending / receiving fax data are constantly set to the products to a value determined by the manufacturer's experiment and verification before release. . At this time, even if the communication line is not good according to the sending / receiving area because the user cannot change the setting value, the user uses the same setting value as it is, and if it is no longer available in the given state, A / S Upon request, the service personnel change and use the existing settings. At this time, the transmission level and the reception sensitivity of the normal transmission / reception area are also uniformly used.

By the way, in the transmission level and reception sensitivity of the conventional facsimile machine or multifunction device as described above, if a predetermined value is uniformly set in the product to be shipped, regardless of the line state of each region to be transmitted / received Because the fax data communication is performed according to the set value, even if the line status is not good when sending or receiving the fax data, the user cannot arbitrarily change the setting to suit the current line status. It became.

In addition, to change the setting value, the user cannot execute the setting change arbitrarily. Therefore, the service personnel must visit and change the value set at the time of shipment. Therefore, it is very cumbersome and the setting can be changed to communicate in good line condition. There was a problem that takes a lot of time.

In addition, when the transmission / reception is frequently performed in areas with poor communication line conditions, even if the transmission / reception in other areas is normally performed, the transmission / reception status is inefficiently operated because it is unavoidably used by uniformly changing setting values. There was this.

Accordingly, an object of the present invention is to solve the above-described problems, and an object of the present invention is to manage this area separately when a communication line condition of a particular area is not good at the time of sending / receiving fax data in a facsimile or multifunction device. The present invention provides a method for automatically adjusting a transmission level and a reception sensitivity when transmitting / receiving a packet.

In addition, another object of the present invention is to count the number of transmissions or receptions for a certain period of time to repeat the operation of calculating the transmission rate or reception rate to manage the transmission / reception state failure of a specific region, so that the transmission level and The present invention provides a method for maintaining reception sensitivity.

SUMMARY OF THE INVENTION A feature of the present invention for achieving the above objects includes: a method of adjusting a transmission / reception state upon transmission / reception of fax data, comprising: a first counting step of counting transmission / reception times; A control step of determining a communication bad area and adjusting a transmission / reception state if the communication is bad area; A second counting step of determining whether transmission / reception is successful and counting the number of successes; Calculating a transmission / reception rate after a certain period of time by determining whether a certain period has been reached; A determination step of determining whether the transmitted / received area is stored as a poor communication area when the transmission / reception rate calculated in the calculation step is less than a reference transmission / reception rate; And a storage step of storing the transmission / reception area and the transmission / reception status if the communication failure area is not stored.

In the above-described feature of the present invention, after the storing step, it is preferable to further include the step of initializing the number of transmission / reception and the number of successful transmission / reception.

According to another aspect of the present invention, in the determining step, it is preferable to include an update step of updating by applying a weight to a transmission / reception state, if it is stored as a communication failure area.

In addition, it is preferable to store the communication failure area and the transmission / reception state in a lookup table format.

Hereinafter, a method of automatically adjusting a transmission level and a reception sensitivity upon transmission / reception of a specific area in the communication of fax data according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a facsimile according to the present invention.

The control unit 110 controls overall control of the facsimile system, the scanner 120 in which the document is read for transmission or copying of data, the data received through the public telephone network or the scanner for copying, and reports on the functions of the facsimile, etc. A printer 130 for printing a control panel, a function key for allowing a user to input an operation of various functions, and an operation panel (OPE) 140 having a display window for notifying a user of the system status. ), A memory 150 composed of an EPROM in which the entire system program is stored to store information of the system, and an SRAM storing various control variables of the system data processing and the facsimile, and modulating data in a form capable of transmitting and receiving data. And demodulation in a form that can be received, and by adjusting the transmission level and the reception sensitivity when transmitting / receiving to a specific area The modem 160 is set to a value suitable for a line and a LIU (Line Interface Unit) 170 for interfacing with a public telephone network.

Operation by the configuration of the above-described facsimile is as follows.

When an original is inserted, the scanner 120 reads the original and immediately transmits the original or stores the original in the memory 150 according to a user's selection by the operation panel 140, and then transmits the data by memory transmission. In addition, the data received from the transmitting side is printed to the printer 130. The performance of all these operations is controlled by the controller 110. At this time, in the fax data communication, the transmitted or received fax data is modified / demodulated by the modem 160 and output or input to the LIU 180 to communicate through a public telephone network. Therefore, when the communication line condition is uneven due to various conditions, when transmitting / receiving with this specific region, the transmission level and reception sensitivity are increased to change and set the modem 160 so that normal data communication can be performed. When this is completed, the original transmission level and reception sensitivity are returned.

2 is a flowchart illustrating a method of adjusting a transmission level and a reception sensitivity for transmitting or receiving a fax data to a specific region having a poor transmission / reception state in the present invention.

First, in transmitting the fax data, when a call path is formed for the transmission of fax data and transmission starts, the transmission number N according to the communication is counted based on the number of transmissions that have been initialized or stored in advance (S21), and the receiving side identifier Determining whether the area to be transmitted is a bad communication area (S22). In the case of a communication failure area, the transmission level and the reception sensitivity are adjusted to a predetermined amount stored (S23). If the communication failure area is not, the data is transmitted at the current transmission level and reception sensitivity (S24). Here, the poor communication area is stored in a look-up table format together with the transmission level and reception sensitivity to be adjusted. It is determined whether the transmission has been successfully completed (S25), and if the transmission is successfully completed, counting the number of successes (S) at the time of transmission (S26), and counting if the transmission is not completed successfully due to an error during transmission. Proceed to the next step without (S26). If the error rate is required at the time of transmission, the error rate may be confirmed in addition to counting the number of successes. After counting the number of successful transmissions, the process returns to the original transmission level and reception sensitivity set at the time of shipment of the product (S27). It is determined whether or not a predetermined time period is reached (S28), and if the predetermined time period is not set, the counted number of transmissions (N) and the number of successes of transmission (S) are terminated. ) And the transmission success rate S, to calculate the transmission rate M = S / N x 100 (%) (S29). Here, the transmission / reception rate is calculated by setting a period of time in order to determine whether the communication line is in a bad state by calculating the transmission / reception rate even in an area where the transmission / reception of fax data is hardly performed. It is determined whether the calculated transmission rate M is less than the preset reference transmission rate (S30), and if the calculated transmission rate M is less than the reference transmission rate, it is recognized as a communication failure area and the transmission area is a communication failure area. It is determined whether the region has been stored in advance (S31). If the area is stored, the weight must be applied again, and the transmission level and the reception sensitivity are updated by a predetermined value and stored (S32). If the area is not stored in the bad communication area, the transmission level and the reception sensitivity are adjusted and stored in the lookup table. (S33). After that, the number of transmissions and the number of successful transmissions are initialized (S34), and the process ends. If the calculated transmission rate M is equal to or higher than the set reference transmission rate, since it is not a communication failure area, the transmission count N and the transmission success count S that have been counted so far are initialized (S34). When the number of transmissions N and the number of successful transmissions S are initialized, the steps S21 to S34 are repeatedly performed to continuously adjust the transmission level and the reception sensitivity according to the detected transmission rate, and at the time of transmission of the fax data. If it is necessary to transmit to a bad communication area in the future, fax data can be sent by automatically changing the transmission level and reception sensitivity. In this way, by repeatedly performing the calculation of the transmission rate for a specific area for a certain period of time, and managing the specific communication area, the transmission level and the reception sensitivity suitable for the communication line condition are always maintained when the fax data is transmitted. Can be performed.

In the case of receiving the fax data by the above-mentioned method, if a call path for receiving the fax data is formed from the sender, the sender determines whether it is a defective communication area, and if the fax data is received from the defective communication line, the transmission level And reception sensitivity. In addition, the reception rate is calculated by counting the number of receptions and the number of successful receptions, respectively, and when the calculated reception rate is less than the set reference reception rate, it is recognized as a communication failure area and stored simultaneously with the adjusted transmission level and reception sensitivity in the lookup table. When receiving the fax data from the communication poor area, it is possible to automatically change the transmission level and the reception sensitivity to receive the data. Here, by repeatedly performing the calculation of the reception rate for a certain period of time, it manages a specific communication failure area and always maintains an optimal reception state.

Therefore, in performing transmission / reception to a specific communication failure area during transmission / reception of fax data according to the present invention, the transmission / reception count and transmission / reception success count for a predetermined period during fax data communication are counted. After calculating the reception rate, compare it with the established transmission / reception rate, and store the bad communication area below the standard transmission / reception rate in the lookup table, and automatically adjust the transmission level and reception sensitivity to send / receive fax data to these areas. Will be.

After all, according to the method for adjusting the transmission / reception state for a specific region in the fax data communication according to the present invention, the transmission / reception rate is counted by counting the number of times of transmission / reception and number of successes of transmission / reception for a predetermined period, and the calculated value If you configure the lookup table to manage bad communication areas that are less than the standard transmit / receive rate by comparing with the set standard transmit / receive rate, the transmission level and receiving sensitivity By adjusting the communication of the fax data, there is an advantage that can perform a successful transmission / reception.

In addition, after a certain period of time, it initializes the number of transmission / reception and calculates the transmission / reception rate for a specific area again, and repeatedly adjusts the transmission level and reception sensitivity for each specific poor communication area and stores it in the lookup table. By doing so, there is an advantage of always maintaining a transmission level and reception sensitivity suitable for a communication line condition for transmitting / receiving fax data in some regions.
