摘要： PURPOSE:To detect the continuation of bus occupation by a specific unit and disconnect a faulty unit by a processor where many units having bus control right are connected to one bus. CONSTITUTION:Each unit which outputs a bus request to a bus control unit 3 from a bus switching circuit 4 and occupies the common bus 2 corresponding to a bus occupation permission signal sent back from a bus priority decision circuit 6 is provided with a bus busy state monitor circuit 5 and the bus request signal is cut off after a constant time from the output of the bus busy state signal is clocked to stop the bus busy state signal. Further, the bus control unit is provided with a bus control decision circuit 7 to latch the bus occupation permission signal, provided with a bus monitor circuit 8 to clock the constant time after the generation of the bus busy state signal, and also provided with a bus request gate circuit 9 to cut off the input of the bus request signal corresponding to the latched bus occupation permission signal after the constant time is counted.

摘要： PURPOSE:To shorten time for identifying that from which input/output device an interruption signal is outputted by allowing the input/output device which outputs the interruption signal to count bus clocks and, when the counted bus clocks coincide with a status number, sending pulse signals to a CPU through a serial signal line synchronously with the bus clocks. CONSTITUTION:When a CPU 1 receives an interruption request from one of input/output devices 2-1-2-n through an interruption control line iNT1, interruption identification signals are originated to all input/output devices 2-1-2-n from an interruption control section 11 for a required time. When the devices 2-1-2-n receiving the interruption identification signals generate the interruption, the device counts bus clocks. When the counted number of the bus clocks becomes coincident with a status number, the device sends pulse signals to the CPU 1 through a serial signal line SAKD synchronously to the bus clocks and the pulse signals are further sent to a microprocessor 10. Therefore, the microprocessor 10 can immediately identify the input/output device generating the interruption.

摘要： PURPOSE:To allow a master station always to confirm the occurrence of an event with high importance quickly by disconnecting subsequent stations at a slave station from the master station if any of slave stations connected to the master station in the order with higher priority has a prescribed event. CONSTITUTION:The slave stations 14-1, 14-2,... are connected in the higher priority to a signal line 10 led out of the master station 12 and polling is applied sequentially from the master station 12. If any important status change or fault takes place in the slave station 14-2, a communication interruption detection and control means 24 of the master station is detects the interruption of communication of the slave station 14-2 based on an output from a data reception means 22 and a communication opposite station engaged so far is changed forcibly to the slave station 14-1 with highest priority by an opposite station forced change means 26. On the other hand, when a data monitor means 32 of the slave station 14-1 detects the occurrence of a prescribed event based on the monitor of the data obtained by its own station, a switch 16-1 with the slave station 14-2 being subsequent to its own station is opened by a switch drive means 34.

摘要： PURPOSE:To collect satisfactorily the latest data without imparing power saving by transferring the idle data to a master station in case the polling is applied to a busy state, and renewing data after releasing the busy state to transfer the renewed data to the master station. CONSTITUTION:The water level is measured by a sensor 100 of a telemeter system, and the busy state obtained when the polling is applied from each of switches SA-SD is supplied to AND gates 302A-302D of a measurement controller 300. While the output of a switch SE is supplied to the other side of the gates 302A-302D and one side of AND gates 306 and 310 respectively. The outputs fed from gates 302A-302D are supplied to a memory 304, and the idle data is transferred to a master station from a communication device 400. Then the output of an FF is supplied to the gates 306 and 310, and the outputs of gates 310 and 306 are supplied to a timer 312 and the memory 304, respectively. The data of the memory 304 is renewed after the busy state is renewed. Then a relay switch RS is actuated to transfer the latest data to the master station.

摘要： PURPOSE:To attain the transmission of an important data at maintenance communication by transmitting a data and a voice signal to a transmission line via a branching filter. CONSTITUTION:Switches SW1, SW2 are thrown normally to the postion shown in solid lines and the data collection between a master station 2 and a slave station 1 is conducted, and the important item priority transmitting function is provided to parallel/serial and serial/parallel converters PSP 4, 9. In case of the maintenance communication between the slave station 1 and the master station 2, when telephone sets 8, 13 are hooked off, the switches SW1, SW2 are thrown to the position shown in dotted lines and the PSP 4, 9 attain to the state of important item priority transmitting state. Then the maintenance communication is conducted through the switch SW1, transmission line 3, the SW2 and a branching filter 12 and the transmission of the important item data is conducted through the PSP4, a 200-bit/s data transmitter 6, the branching filter 7, the SW1, the transmission line 3, the SW2, a data transmitter 11, and the PSP9. Thus, the data of important item is transmitted at even the maintenance communication.

摘要： PURPOSE:To shorten the recovery time at the time of fault, by automatically performing loop back operation through operation from a central terminal office. CONSTITUTION:If a fault occurs on a transmission line, loop test switch 62 of central terminal office 32 is operated to change its moving contacts over to side N/E and TST. Assuming that in-use circuit 34 between loop control units 44-1 and 44-2 is cut, current detector 54-1 is not in operation and detection output S4 stays at a low level. Therefore, FF80 is not set and the output of AND gate 86 is at a high level; and a clock pulse is applied from timer 90 after the prescribed time, so that the output of FF reachs the high level. As a result, driving circuit 58b is energized to close loop back switch 58a, so that in-use circuit 34 and stand by circuit 36 are connected together electrically.
