摘要： A multiplex transmission apparatus in accordance with the present invention is interconnected with other multiplex transmission apparatuses via common transmission lines, and it is used for a multiplex transmission system which performs data transmission. The multiplex transmission apparatus comprises voltage converting circuits which detect voltages of the transmission lines, the first comparator which compares the detected voltages, the second comparator which compares one voltage of the detected voltages with a reference voltage, and the third comparator which compares the other detected voltage with a reference voltage. The comparators supply the comparison results to differential circuits, respectively, set the output of the differential circuit linked to a comparator, which is connected to a faulty line, for "L", and determine the logical sum of the outputs of the differential circuits by a logical synthesizing circuit. By applying the determined logical sum to a multiplex transmission control circuit, the apparatus makes it possible to reduce wasteful message transmission and successfully cope with faults in the transmission lines without causing delay in transmission of messages which require quick responses and without increasing the traffic volume of the transmission lines. The multiplex transmission control circuit detects signals on the transmission lines according to the comparison results of the comparators.

摘要： A multiplex transmission system of this invention includes a plurality of multiplex nodes interconnected by a common multiplex transmission line. A frame of data is transmitted among the multiplex nodes through the multiplex transmission line. When a data frame transmitted from an air conditioner switch multiplex node (subnode) is received, an air conditioner unit multiplex node (main node), which is predetermined as a destination node, detects the contents of each data from an ID-a of the received data, performs a calculation on SOM to DATA 4 received, generates collation data (CRC) in accordance with the result of the calculation and transmits same. The subnode generates collation data (CRC), which is an error check code, through a calculation on the transmitted SOM to DATA 4, and compares the thus-generated CRC with the CRC received from the main node, to determine whether or not the data transmission was properly carried out. When the data transmission was carried out properly, the subnode returns a signal ACK3, and when the data transmission failed, the data frame is retransmitted, whereby the subnode need not have an ACK management function.
