The present invention relates to a response control method of a line that returns a response by using the line.

再送を繰返すことが起る。(2) Conventional Technology and Problems Conventionally, a system having a plurality of work terminals under the control of a control station has been used. FIG. 1 is an example thereof, in which work terminals (WS) 2 1 , 2 2 controlled under the control station 1 are provided,
To send an inquiry from the control station 1, it is performed response process from working terminal eg WS2 1 In task processing unit 11-2. If this case is in operation in the task processing unit 11-2 except task A11-3 does not abandon the long-running right, an interrupt is performed to WS2 1 interrupt processing unit 11-1, after the interrupt process is completed The execution right is returned to task A11-3, and a long time is secured again. Therefore, the execution right is not transferred to the task processing unit 11-2 and the control station 1
Control station 1 because the response to the call of
In, it is not possible to check the processing status for interrupts,
Repeated retransmissions may occur.

As shown in (a), the call signal B from the control station 1
Interrupt to WS2 1 forward A is performed, and another task A in this case the figure (c) is in operation. And the figure (b)
As shown in (c), when the call signal a of the control station 1 arrives, the execution right shifts from the task A of FIG. The interrupt processing unit 11-1 is divided into three steps corresponding to the calling signal B as shown in the figure. The procedure is the reception interrupt processing stage, which determines whether it is data or command, and then WS2 1
An external timer is started at. In the next procedure, the period of mode switching on the control station 1 side is set at the timer running stage, and task A is run from D during that period. The procedure is the time-out interrupt processing stage, which is the end of the interrupt processing. However, when the conventional interrupt ends, the execution right is returned to the original task A in FIG. 7C, and the task A is continued from E.
このタスクＡが次に到来する呼出信号ロ以前に終了しな
い場合には、さらに次の呼出信号の周期に処理が移行す
る。If this task A does not end before the next incoming call signal B, the process shifts to the cycle of the next incoming signal.
このように、WS21のタスク処理部11-2に制御権が移らな
いから仲々レスポンス(RS)が返らないため、呼出しの
再送を必須とすることが起つた。Since the not returned is Naka s response (RS) because there is no Utsura control to WS2 1 task processing unit 11-2, the stand be a mandatory retransmission call.
これに対する対策として、タスクが長時間実行権を放棄

がよいとは言えない。As a countermeasure against this, if a task does not abandon the execution right for a long time, a separate channel is provided and a response is returned. However, the procedure for this is complicated, and since this channel is not always used, it cannot be said that the utilization efficiency is good.

Work having a line control unit including a task processing unit that executes processing according to the ringing signal and returns a response to the ringing signal after a predetermined timing time for mode switching of the control station has elapsed In the terminal, when a time-out interrupt for notifying that the predetermined timing time has elapsed in response to a call signal from the control station, the task that has been suspended for the time-out interrupt processing Prior to resuming, the interrupt processing unit returns a response to the control station, and after the response is returned, the interrupted task is resumed.

監視することができる。(5) Embodiments of the Invention In the prior art, when a call is made from the control station to the work terminal, the execution right is temporarily transferred from the task being processed to the interrupt processing unit of the line control unit, but automatically after the interrupt processing is completed. There is a problem in that it cannot return a response to the control station within the specified time by returning to the original task. In the present invention, the interrupt processing status can be monitored by returning the response to the control station immediately after the completion of the interrupt processing.

The difference from the conventional example of FIG. 2 is that the call signal of FIG.
As shown in the interrupt processing section of FIG. 7B, the call signal is the first
Interrupt signal from the control station 1 to WS2 1 interrupt processing unit 11-1 in Fig are sent after processing through the same steps ~ and Figure 1, by returning a response to the control station 1 within the specified time is there.

するような事態の発生を避けることができる。(6) Effects of the Invention As described above, according to the present invention, when an interrupt is issued from the control station in a work terminal that generates a call signal from the control station and returns a response, the execution right is temporarily assigned to the task being processed. The process moves to the ingress side, but the control is such that a response is returned to the control station when this interrupt processing is completed. As a result, the response is compensated even when the task being processed does not abandon the execution right for a long time, so that it is possible to avoid the occurrence of the situation of retransmitting as in the conventional case.

御することを特徴とする回線レスポンス制御方式。1. An interrupt processing unit which, when receiving a call signal from a control station, accepts an interrupt based on the call signal, executes a process according to the call signal, and responds to the call signal. A work terminal having a line control unit including a task processing unit that returns a response after a predetermined timing time for switching the mode of the control station has passed, and the predetermined operation is performed in response to a call signal from the control station. When a time-out interrupt for notifying that the timing time has elapsed has occurred, a response is sent from the interrupt processing unit to the control station before the restart of the task suspended for the time-out interrupt processing. A line response control method, wherein the line response control method is characterized in that after the response is returned, the suspended task is restarted.
