At this time, by providing double loop transmission lines 1 and 2, even if one of the loop transmission lines fails, data transmission can be carried out as usual, and high reliability is achieved. At the same time, in certain station control devices, for example 4 and 6, the internal processing control devices are also dual-configured, so-called duplex systems, and in certain highly important stations, functions due to failures within the station control device This ensures that no deterioration or loss of function occurs. In addition, in general, non-linked stations do not have dual systems, but linked stations often have dual systems.

6, two processing control devices 15 and 16 are provided as a pair, and these monitor each other's operations and operate as the main system in the dual system according to predetermined logic. Forms a subordinate system. By registering the same code indicating the content of the data to be received in the transmission control devices 11 and 12, the same data is received from the loop transmission paths 1 and 2 via the transmission control devices 11 and 12, respectively. are doing. On the other hand, the same data is also being received in parallel from the track circuit of the own station via the input Di.
Therefore, these dual system processing control devices 15 and 16 each receive the same data and thereby generate their respective control outputs, but among these, the data output to the switching device 18 is the same as that described above. Based on the determination of the main system and the slave system, the switching device 18 is switched, and only the output of the main system is taken out, and the data output to the transmission control devices 11 and 12 is similarly suppressed for the slave system. Therefore, only the data of the main system is sent to the loop transmission lines 1 and 2.

ある。 By the way, according to such a signal transmission system, the loop transmission lines 1 and 2 are double loop transmission lines, and relatively important stations such as interlocking stations are equipped with dual system station control devices 4, 6, extremely high reliability can be obtained as described above, but on the other hand, transmission control devices 15 and 16 for duplex systems and transmission control devices 13 and 14 for single system are provided as transmission control devices. Since two types of materials are required, the disadvantage is that the cost tends to increase. In other words, as is clear from FIG. 2, since two processing control devices 15 and 16 must be connected to the loop transmission path 1 or 2, two transmission control devices 11 and 12 for the duplex system must be connected to the loop transmission path 1 or 2, respectively. processing control device 2
Naturally, the hardware configuration is different from that of the transmission control devices 13 and 14 for a single system, which only need to connect the transmission control device 5 to the loop transmission path 1 or 2. Since it is commonly used, the software configuration will be different in this case.
As a result, in conventional signal transmission systems, the number of types of transmission control devices increases, leading to an increase in costs.
