[ switching Module ]
As shown in fig. 3, a switching module is provided between the I and II families for selecting which is the primary family and which is the backup family between the I and II families. The switching module may be, for example, a selection switch constituted by a key switch for the operator to manually select.
The key switch may be set to have three positions of a left position, a middle position and a right position.
When the key switch is switched to the left position, the selection I is the main system and the selection II is the backup system.
When the key switch is switched to the right position, the selection II is the master and I is the backup.
When the key switch is switched to the neutral position, the master and backup trains are allowed to be selected by other means. For example, the operator may select which of the I and II systems is the master system and which is the backup system at the computer terminal at this time, or directly automatically select which of the I and II systems is the master system and which is the backup system by software in the computer.
[ channel A and channel B ]
Both channel a and channel B are in signal connection with the I and II systems via the communication module. Channel a and channel B may be optical fibers or communication lines conforming to ITU-T g.703 standards.
When channel a and channel B are optical fibers, they may be single mode fibers, employing interfaces of specifications such as FC, SC, ST, etc. In this embodiment, an optical fiber suitable for the test wavelengths 1310nm and 1550nm can be used. Since the optical fiber has a small signal loss, it is particularly suitable for safely and reliably transmitting signals over a long distance of 30km or more without relaying.
When the channel a and the channel B are communication lines (hereinafter referred to as E1 channels) conforming to the ITU-T g.703 standard, a transmission rate of 2MB can be realized in the E1 channel, which can also satisfy the demand for safe and reliable signal transmission over a long distance of 30km or more without relaying. In this case, the E1 tunnel needs to be connected to an ethernet interface provided in the semi-automatic block control unit.
[ communication Module ]
The specific construction of the communication module varies depending on the type of channel a and channel B.
For example, when channel a and channel B are E1 channels, the communication module may include the communication board and two ethernet interfaces shown in fig. 4. The data signals transmitted by the channel A and the channel B can enter the two-by-two-out-of-two main control unit through the communication board. When the two-by-two-out-of-two main control unit is arranged in the I main control board, the communication module is in signal connection with the I main control board. When the two-by-two-out-of-two main control unit is arranged in the acquisition module, the communication module is in signal connection with the acquisition module and is further in signal connection with the I-system main control board through the acquisition module.
For example, when the channel a and the channel B are optical fibers (i.e., optical channels), the communication module may include the photoelectric conversion portion and the communication board shown in fig. 4. The optical fiber is connected to a photoelectric conversion portion, where an optical signal in the optical fiber is converted into an electrical signal of a predetermined format, and then the electrical signal is transmitted to a communication board through a data line of, for example, RJ45-1 specification. The communication board performs data processing on the received electric signals according to a preset specification and then transmits the electric signals to the two-by-two-out-of-two main control unit.
Data transmitted between semi-automatic block system stations through the channel A and the channel B need to be coded, and information transmission is restrained in a mode of defining a larger code distance. Examples of such codes are given below in connection with table 3.
