摘要： PURPOSE: To shorten the time from when a train enters a blocking section until a train entry signal is generated without harming the train detecting capac ity. CONSTITUTION: A train detecting signal from a transmitting circuit 4 is transmitted to a rail 1 from the exit side of a blocked section T through a transmitting coil 2 and the train detecting signal is received by a receiving coil 3 at the entrance side of the blocked section T. If a level examination of the train detecting signal level received conducted by a train detecting first level examination circuit 6 and a train entry detecting second level examination circuit 7 is found below the respective threshold values, a train on-rail detecting signal is generated by dropping a relay 8 by the first level examination circuit 6 and a train entry detecting signal is outputted from the second level examination circuit 7 to the transmitting circuit 4. The threshold of the first level examination circuit and that of the second level examination circuit are set higher on the second level examination circuit side.

摘要： PURPOSE:To obtain a compact size and easy adjustment and also detect three different-phase, i.e., similar, opposite and none phase signals by installing local inputting circuit, track inputting circuit and processing circuit, having the respective specific functions, and electronizing functions of a track relay. CONSTITUTION:A local inputting circuit 1 generates a reference signal S4 when a local signal S3 of similar or opposite phase in respect to a transmitting signal S1 changes in between positive and negative. A track inputting circuit 2 A/D converts a track signal S5 and outputs it as a track output signal S6. A processing circuit 3 stores a phase difference from the time when the reference signal S4 is inputted to the time when the track output signal S6 reaches to crest value as a reference phase difference. And further, the circuit 3 multiplies the crest value by a cosine value between a phase difference based on a reference output signal S6 and a phase difference. And thus, detection signals are outputted, as follows; a similar phase signal when the multiplied value is above a positive reference value, an opposite phase signal when it is below a negative reference value and a none phase signal in other cases.

CONSTITUTION:A track 11 is divided into block sections 1T, 2T... Ground units 121, 122... transmit control signals S1 including information on at least their own block numbers other block numbers, having limit speeds and the limit speeds of the blocks. An on-board pickup 21 receives the control signals S1. A speed detector 22 detects the running speed of a movable body 3 and outputs a speed signal S2. A control circuit 23 stores intervals L1 and L2 and the brake characteristic of the movable body 3, computes a running distance- allowable speed characteristics A from its own block section 1T to another block section 3T by decoding the control signal S1, computes also the running distance of the movable body 3 from the speed signal S2, determines an allowable speed of the movable body 3 from the running distance-allowable speed characteristic A and executes a control so that the running speed be the allowable speed.

摘要： PURPOSE:To obtain a sufficient transmission speed without being affected of a disturbing wave of a power supply by sending a frame of a divided digital transmission data through separated transmission channels simultaneously. CONSTITUTION:A data generator 12 of a transmitter 1 converts an inputted transmission data into digital transmission data of frame constitution and divides a 1st frame comprising a start flag and a first half of the transmission data and a 2nd frame comprising a latter half of the transmission data and a CRC code for check. First and 2nd frequency shift keying(FSK) modulators 13, 14 FSK-modulate the 1st and 2nd frames respectively and the frames are assigned to 1st and 2nd channels respectively. Then the data FSKmodulated separately are synthesized by an adder 15 and outputted to a rail 3 as a transmission signal via an amplifier 16 and a transformer 17. Thus, a sufficient transmission speed is attained with a small sized device without being affected of a disturbing wave of a power supply.

摘要： PROBLEM TO BE SOLVED: To secure the continuity of digital data, when changeovers are performed between systems in the structure of multiple systems. SOLUTION: This device includes an on-board device 1 and a ground device 2. The on-board device 1 receives the digital data transmitted from the ground device 2, which has systems A, B that transmit the digital data in a frame unit. The system A constitutes a custom system, while the system B constitutes a stand-by system. When the normal system A is changed over to the stand-by one B, the stand-by system B transmits the one frame of the digital data from the beginning of the frame.

摘要： PURPOSE:To disconnect individual repeaters without restrictions due to cable length by turning off a power source in the case of disaccord between data sent from a main body to a ground slave and data returned from the ground slave to the main body. CONSTITUTION:Prescribed data is cyclically sent to ground devices p1 to pn from a data generating circuit 2b of a main body 1, and data from a vehicle is transmitted from each of ground devices p1 to pn to the main body 1. On the other hand, a return signal corresponding to data sent to each of ground devices p1 to pn is transmitted to the main body 1 and is collated by a collating part 3. That is, the collating part 3 collates it with data from the ground device side based on data sent from the main body 1; and if they do not coincide with each other, the normal operation relay of the pertinent ground device is dropped-Consequently, the power source of the ground device corresponding to this normal operation relay is turned off to stop the function.
