うイ呂中真性■η保の意味がある。As shown in Fig. 1, the transmission device sends the signals of each company in process 1 to a distant place (2) using a transmitter 2.The transmitted signal is received by a receiver 3 and outputted to a process 4C.The transmission device is reliable. If required, further install a vessel 5 and a receiver (N vessel 6) on the source.
Same process! A signal of 2 is output to process 4C. In this duplex signal transmission C2, if the signal is a contact signal, in process 4 the two contacts 4 are connected as shown in FIG.
%, i.e. output 11 of receiver 3 and output 1 of receiver 6
2! a = Nt (AND circuit) r is often used. This is to output a contact signal to the process 4 only when both the receiver 3 and the receiver (i) 6 output a signal that simultaneously closes two circuits, and the contact signal is output to the process 4. Or 8
Even if the receiver 5 and the receiver 6 malfunction, there is a sense of protection in order to ensure that no adverse effects are caused by the incorrect output of the process 4C2.

略する。-I: In order to achieve the objective 1, in the present invention, in a duplex transmission device that transmits multiple contact signals, the output contact of one transmission system 1 is connected in parallel to the output contact of one transmission system 1, and when the transmission system 1 fails A circuit connected in parallel to the output contact of the other transmission system 2 and bypassed when the transmission system 2 fails, a series circuit of the upper output contact, and a circuit directly connected to the transmission system 1 or the transmission system 2. It is explained that a circuit that is connected to the closed circuit is provided under the condition that either of the two is normal. Figure 3, Figure 4, Figure 1,
Components with the same functions as those in FIG. 2 are given the same numbers and their explanations will be omitted.

Signals 41, 42, 43, and 44 are all signals that open the circuit (contact) in the event of a failure. In other words, it is a signal that is normally closed. Therefore, when both transmitter 2 and receiver 3 are normal, the input circuit of relay Xt is closed and relay Xi is energized. Further, when both the transmitter 5 and the receiver 6 are normal, the input circuit of the relay X2 is closed and the relay X2 is activated.Now, the output to the process 4 is configured as shown below. (When the M unit 2 and receiver 3 are normal, the open or close of the circuit is determined by the output 11 of the receiver 3, but when it is abnormal, the output 11 is bypassed.) Xlb (contact that closes when relay The relationship between the transmitter 6, the output 11, and the relay The condition that either relay Xi or relay X2 is energized (logical sum of Xl and Xl) is connected in series to the output circuit so that it is not closed by the bypass circuit.

合も同様である。In the present invention having the C2 configuration as described above, for example, if either the transmitter 2 or the receiver 3 fails and transmission becomes impossible, the relay XI is no longer energized and the bypass circuit (xl As long as the transmitter 5 and receiver 6 are normal, the output circuit to process 4 will be output ■2.
It depends only on the state of . Transmitter 5 and receiver 6
The same applies when either one of the transmitter 2 and the receiver 3 is normal but one of the transmitter 2 and the receiver 3 is normal.

Since the bypass circuit No. 2 is open, a logical product output with guaranteed reliability is obtained.

Furthermore, since a circuit is added to ensure that the output circuit C is opened in the event that both transmission systems fail, troubles caused by an incorrect signal section ζ are eliminated. Moreover, since the logic circuit from failure detection is configured by hardware separate from the transmission device, it is not affected by the negative effects of 17 dI due to the failure of the transmission device, and can reliably transmit and receive contact signals from various companies.
