摘要： PROBLEM TO BE SOLVED: To provide an automatic train control device capable of transmitting relatively much train control information by setting a frame length of transmitted code information so short as to take a time capable of receiving one frame at a minimum on a vehicle by considering the passing time of a train in a short and small track circuit, by setting only minimum required information as an information content, and by keeping the information of an outside track circuit as information other than that. SOLUTION: In a ground device 1, when a track circuit length is determined by a track circuit length determination part 1a, a frame length of 1/2 or less of a time for the train to pass the short and small track circuit is set in the control information of the short and small track circuit, and a short and small kind track circuit control signal having set the short and small track circuit control information is transmitted to a rail 2 by a transmission control part 1d. In an on-vehicle device 4, when the short and small track circuit control signal carried to the rail 2 from the ground device 1 is received by a receiving antenna, and it is confirmed that all frames set in the short and small track circuit control signal has properly received, the short and small track circuit control information set in the short frame is deciphered by decoding it.

摘要： PROBLEM TO BE SOLVED: To provide a ground device for an automatic train controller capable of composing an ATC signal without relying on a pilot signal and being used in common with a feed division control track circuit device by one set of a transmitter and receiver. SOLUTION: A track circuit transmission and reception part 10 of this ATC ground device 100 is provided with an ATC transmitter 20 sending the ATC signal S2 to a track circuit 2, an ATC receiver 30 receiving the ATC signal S2 from the track circuit R2, a transmission control part 40 transmitting position information of a train C in the other track circuit on a route, and a feed division switching control part 50 sending a switch signal for feeding to a feed division section 290. The ATC signal S2 is a train detection signal detecting the presence of the train C on a track in a specific track circuit R3 and is provided for feed switching control operation switching feeding in wiring power supply. Moreover, since the pilot signal S4 is not introduced from a wire L1, the presence of the train C on the track can be judged by the ATC signal 32 irrespective of the presence or absence of power failure of the wiring power supply.

摘要： PROBLEM TO BE SOLVED: To provide a communication system, which detects and notifies the duplicate setting of a position number between a plurality of terminals connected to the same LAN. SOLUTION: A CPU 11a fetches specific number information stored in a data area, corresponding to a position number set on the basis of the set position of a terminal 11 among data made to flow on the LAN, and collates this specific number with an specific number that is stored preliminarily in a ROM 11b. When the specific numbers do not match with each other, the CPU 11a transmits an abnormality signal to a display device 21 and also overwrites the specific number which is allocated to data circulating on the LAN and is stored in the data area corresponding to the position number, set on the basis of the set position of the terminal 11 with the specific number that is stored preliminarily in the ROM 11b.
