An RNG circuit is connected to the parallel port of a computer. The circuit includes a flat source of white noise and a CMOS amplifier circuit compensated in the high frequency range. A low-frequency cut-off is selected to maintain high band-width yet eliminate the 1/f amplifier noise tail. A CMOS comparator with a 10 nanosecond rise time converts the analog signal to a binary one. A shift register converts the serial signal to a 4-bit parallel one at a sample rate selected at the knee of the serial dependence curve. Two levels of XOR defect correction produce a BRS at 20 kHZ, which is converted to a 4-bit parallel word, latched and buffered. The entire circuit is powered from the data pins of the parallel port. A device driver interface in the computer operates the RNG. The randomness defects with various levels of correction and sample rates are calculated and the RNG is optimized before manufacture.

The invention discloses a train control system adapting to existing line reconstruction. The train control system adapting to existing line reconstruction comprises ground equipment and on-board equipment. The ground equipment comprises an interlocking system, a parallel-port LEU and an active balise which are mounted in a station and connected sequentially, wherein the parallel-port LEU combines contact states of the interlocking system into access selection conditions and sends station messages to the corresponding active balise, and when a train passes through an acting range of the active balise, the active balise sends the corresponding station message to the on-board equipment of the train. The on-board equipment comprises a BTM (balise transmission module), a BTM antenna and an automatic train protection system, wherein when the train passes through the acting range of the active balise, the BTM receives the station messages sent by the active balise and sends the station messages to the automatic train protection system for subsequent processing. The train control system adapting to existing line reconstruction has the advantage that access information is sent to the on-board BTM through the station messages to enable a driver to acquire correct access information directly, so that the train pull-in risk that the driver selects wrong access information due to misoperation is avoided.
