本発明は、通信回線を介してデータ伝送を行うシステム
に関し、データ伝送による回線の使用率測定装置に関す

としていた。Conventionally, this type of measuring device either measures the number of characters or data bits actually transmitted or received before transmission or after the reception process is completed, or it is held in a data transmission device where actual data transmission is not performed. The line usage time was calculated based on the time.

ある。Therefore, if the terminals housed in the exchange or the central processing unit accommodating each terminal do not have sufficient capacity, it will be difficult to accurately grasp the communication volume of each terminal, and appropriate circuit design will be required. I couldn't do it. The present invention makes it possible to measure the actual usage time of the line due to data transmission by adding a pulse generation circuit and a counter to the detection circuit for synchronization information, that is, start and end identification information, which is indispensable when transmitting and receiving data via a communication line. The present invention provides a device that does this.

である。In this embodiment, a generally widely known SYN synchronous data transmission system will be described. In this data transmission system, in order to receive data transmission characters, it is mandatory to transmit two or more consecutive SYN characters before the required data. The data receiving device uses this detector to determine the start of data transmission and reports it to the control device. Note that the end of data is determined by a control character called ETB or ETX. The present invention utilizes the control numbers A and B, which are the above-mentioned essential functions in a data device, and uses a set-reset type flip-flop and a clock circuit. is counted by a counter C to obtain the cumulative data transmission time.

カウンタの比を求めることで云わゆるアーラン量を求め
るようにすることは簡単に推測できる。Although this method calculates the accumulation of communication time, it is also possible to calculate the so-called Erlang amount by calculating the accumulation of idle time, which is the opposite of communication time, and finding the ratio of both counters using a similar method. It's easy to guess.

用いた非同期万式についても同様に適用できる。Further, calculation of these counter quantities and Erlang quantities may be performed on the control device side, and it is also conceivable to add an arithmetic circuit and a display circuit to this device. In this system, a synchronous transmission system using SYM characters is shown as a data transmission system, but it can be similarly applied to an asynchronous transmission system using start/stop bits.
