    摘要： Transmission line groups consisting of a plurality of loop-like transmission routes (1...5, 10...50, 100...500) are mutually connected via transmission controllers and are arranged in a two- or three-dimensional space. Processing units are thus connected as a homogeneous network in matrix or mesh form by means of the loop-like transmission routes The transmission controllers corresponding to the nodes (11...51) of the network have a communication management function such that they send the data without grasping the situation on the transmission routes, independently check the trouble between the adjacent transmission controllers, and specify the position of trouble. A communication network system such as a high local area network (LAN) or the like can be realized.

    摘要： The present invention provides, in a system having a plurality of transmission control units (11-14, 21-24) which are connected to at least one circular type transmission line (1,2), a method of automatically checking the overlap of the addresses (N,-N 6 ) of the transmission control units in the circular type transmission system or automatically detecting the structure of the system. In addition, in a double loop transmission system which accompanies bypassing, a bypass route (41-44; 51-54) is constructed in correspondence with the occurence of a fault in the system, and hence, the structure of the system changes. A conventional double loop transmission system does not include means to recognize the structure under which the system is presently operating, and this has been problematic in the maintenance of the system. The present invention is characterized in that the transmission control unit sends an address train message when, for example, it is to be started or it releases the bypass route, that the transmission control units having received the address train message enter their own addresses in succession so as to deliver the resulting messages to a transmission line, and that the source transmission control unit analyzes an address string in the message so as to check the presence or absence of the transmission control unit having the same address as the address of its own. Moreover, the analysis makes it possible to recognize the system structure at that time.

    摘要： A loosely coupled multiprocessor computer (1) includes an input/output control unit (34, 35) for fetching both a program and data derived from an external input device and also for outputting processed data to an external output device; storage (32) for storing therein both the program and data inputted from said input/output control unit; process unit (33) for sequentially executing a processing operation of the data based upon the program stored in the storage; and, a transmission medium for coupling the process unit, input/output control unit and storage with each other. In the loosely coupled multiprocessor computer, a serial transmission medium (2) is employed as the transmission medium; transmission control unit (31) for performing both a conversion process between data to be transmitted, flowing through the serial transmission medium and the processed data, and also a transmission/reception process of the data to be transmitted via the serial transmission medium, is provided with the input/ output control unit, storage and process unit; and furthermore, unit process unit for controlling the input/output control unit, storage, and transmission control unit is provided with the input/output control unit and storage with the transmission control unit.

    摘要： A machine tool controlling subsystem for use with a distribut­ed system comprises a plurality of such subsystems (11, 21, 41; 12, 22, 42...1n, 2n, 4n), each of which includes a machine tool, and a transmission medium (30) operatively associated with said subsystems for transmitting information to said sub­systems. Each subsystem includes means (11, 12...1n) for in­dependently determining whether or not the machine tool is operated based on the received information from said trans­mission medium, and means (41, 42...4n) for operating said machine tool based on the determination of said independently determining means.
