摘要： A data transmission system that permits data with the top priority to be transmitted preceding the other data when collision occurs in a data transmission network with a plurality of terminals. Each terminal (A, B, C) monitors the bus for a predetermined period (Tp) after the bus line becomes empty but immediately before the terminal is ready for data transmission so that, on detecting a signal on the bus during this predetermined period (Tp), the terminal starts transmitting data synchronously with the detected signal. As a result, data with the top priority is always allowed to pass through the circuit preceding other data despite a cl6ck pulse difference between the terminals.

摘要： A signal transmission system which constantly allows data with the top priority to pass preceding others in a bus-type network. In transmitting a packet consisting of a plurality of start-synchronized frames, the bus is monitored for a predetermined period after the first frame transmission. If a frame-start signal is detected during this predetermined period, the next frame is promptly transmitted synchronously with the detected frame-start signal. If no frame-start signal is detected during this period, the next frame is transmitted immediately after the predetermined period elapses. As a result, each frame by a transmitting terminal starts at the same time as that by another terminal. Therefore, so long as the clock pulse error between the different terminals is small enough to permit a frame transmission, the terminals can detect collision for each frame. As soon as either of the terminals detects collision, it stops data transmission, whereby a packet with the top priority is always permitted to pass.

摘要： A signal transmission system for communicating over the power supply wiring of a building is disclosed. The system includes transmission apparatus (15, 16, 17, 18, 21) which is operable to transmit data by superimposing data pulses on the power supply voltages and a receiving apparatus (11, 12, 13, 14, 21) which is operable to count the data pulses so as to derive the transmitted data. The transmission apparatus is operable to transmit a digital value (1,0) by sending different numbers of pulses in a first transmission interval (1;2), and a subsequent transmission interval (3;4), respectively, and the receiving apparatus includes a noise reduction circuit (14) which is operable to determine the difference between the numbers of pulses (A, C; B, D) received during said first and subsequent transmission intervals and to treat the pulses as representing data only if the difference (1A-C1; 1B-D1) exceeds a predetermined value.

摘要： A signal transmission system utilizes the building or house wiring as the data transmission line. A frequency detection system is required to detect a frequency of the power voltage. The frequency detection system includes a zero-cross level detection circuit for developing a detection output when the zero-cross is detected. A timer element is provided in the frequency detection system, which functions to neglect an output signal from the zero-cross level detection circuit for a preselected period of time after the last detection output has been developed from the zero-cross level detection circuit.
