摘要： PURPOSE: To attain asynchronous/simultaneous data transmission and power reception on the remote side by providing a sensor device with a power supply and plural receivers and connecting plural remote units to which different frequency bands are allocated through a common coaxial cable. CONSTITUTION: A buffer board 2 supplies AC power to the coaxial cable 4. Each of remote units 6 receives the AC power through the cable 4, converts the AC into DC and energizes an analog serial bus interface and other node elements. An interface IC samples low frequency sensed by a low frequency sensor 8, encodes the sampled low frequency and transmits the encoded contents through a specified channel. Since respective units 6 have respectively different allocation frequency bands, signals from a high frequency sensor 10 can be also transmitted. A frequency divided/multiplexed signal generated by each unit 6 is demodulated by a receiver 12 tuned to the specified channel frequency. Even when a sensor signal is an encoded signal, the signal is decoded and supplied to a computer 14.

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 simplify the transmission controlling means of a branch circuit by dividing the using frequency of the circuit into prescribed frequency and assigning the divided frequency to each local station. CONSTITUTION:A distributor 30H of a collecting MODEM30 distributes a carriers from a receiving (R) line of a circuit 28 to respective simplex MODEMs 30A-30F and a collecting device 30G synthesizes carriers sent from the respective simplex MODEMs 30A-30F in every frequency band and sends the synthesized output to a sending (S) line. In case of transmission, each simplex MODEM discriminates a band to which an SD signal belongs on the base of indexes A, Z and, after modulating the signal at the corresponding frequency and removing a higher harmonic by a band pass filter which is not shown in the drawing, sends the filtered signal to the circuit. The signal transmitted by said procedure is demodulated by a band-pass filter (not shown) of the corresponding frequency. Consequently, the transmission controlling means of the branch circuit can be simplified equivalently to the point-to-point system.
