摘要： PURPOSE:To ensure the real time performance of each communication packet by assigning respectively a required number of slots to plural stations participating in the network and applying packet communication by the implicit token passing system. CONSTITUTION:The system consists of a station main body 11 connected to a data processing unit and controlling the transmission/reception of a communication packet, a packet transmission reception section 12 connected to a transmission line, a header detection section 13 detecting the kind of a communication packet transmitted to the transmission line and a slot assigning control section 14. The control section 14 has a storage section 15 of a bit corresponding to the transmission slot included in one frame. When a data to be transmitted from the data processing unit to other station exists, the main body 11 applies packets to the data and stores it in a transmission buffer. A transmission/reception section detects sequentially the transmitted packets and fetches packets addressed to the own station. The header detection section 13 detects the kind of the communicated packet from header information.

摘要： PURPOSE:To collect information from a sensor effectively without any problem such as an electric spark by modulating light of different wavelength by pieces of information from plural sensors of a plant, and performing optical wavelength multiplexing and leading light to a sensor information processor. CONSTITUTION:The sensor information processor 1 has light sources which generate light beams having different wavelengths, and light beams from the light sources are multiplexed on wavelength basis and sent to an optical demultiplexer 3 through optical fibers 2a of a wavelength multiplex transmission line 2. The optical demultiplexer 3 demultiplexes the wavelength multiplexed light into light beams having different wavelengths, which are sent to sensors 51-5n through optical fibers 61-6n. The respective sensors modulates input light by sensor output information and sends the modulated light to an optial multiplexer 4 through optical fibers 71-7n. The multiplexer 4 multiplexes modulated signals having different wavelengths on wavelength multiplex basis and sends the resulting signal to the processor 1 through optical fibers 2b. The processor 1 demultiplexes the input light by a demultiplexer and respective detectors detect modulated information. The multiplexer 3, demultiplexer 4, and sensors operate passively and generate no electric spark.

摘要： PURPOSE:To realize an inexpensive optical network system, by changing a high- speed signal into a parallel signal in a circuit speed, or providing a function to restore the parallel signal to the high-speed signal on a network interface. CONSTITUTION:For instance, a camera interface board 5 gives a circuit request to an exchange control part 6 via a system bus 3 when the picture data of a camera 8 is transmitted to a monitor 9. If a 96Mb/s band is needed for transmission of picture data, the part 6 checks whether three idle circuits are available from a circuit state table in an RAM. If three idle circuit are available, the part 6 registers the allotted circuit of the board 5 to the circuit state table and informs the name of the corresponding receiver, the name of the allotted circuit, etc. to a control part 1. At the same time, the control part 6 controls a switch of a circuit switching part 7 and connects the switch to an L port connected to the allotted circuit board 5. While the exchange control part of the part 1 connects the circuit switch part to the interface board of a monitor 9 based on the received information, and the connection end information is sent back to a control part 2. Then the transmission of pictures is started.
