Abstract
Abstract In an inductive radio control system for a vehicle, data transmission between, a vehicle (2) which travels along a travel path (1) provided for a predetermined route and a ground operation control unit (5), is performed by inductive radio means in such a manner that one of the loop antennas (8-I to 8-n) discretely arranged along the predetermined route is coupled to a corresponding transmitter/receiver provided in a ground unit (10) in accordance with the travelling position of the vehicle. The number of transmitters/receivers is the same as the maximum number of operating vehicles (2).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
An inductive radio control system for performing data transmission by inductive radio means between traveling means (2) which travels along a travel path (1) formed in a predetermined route and ground operation control means (5) so as to control the travel of said traveling means (2) in response to a control signal (Sll) from said ground operation control means (5) and receive a monitor signal (S12), characterized by comprising: a plurality of loop antennas (8-1 to 8-n) arranged discretely along said travel path (1); transmitting/receiving means (140) for transmitting the travel control signal and the monitor signal to said traveling means, the number of said transmitting/receiving means being the same as the maximum number of operating traveling means; and selecting means (144, 145) for selectively coupling one of the loop antennas (8-1 to 8-n) with said traveling means (2) so as to perform data transmission by inductive radio means, said loop antennas (8-1 to 8-n) being arranged discretely along the predetermined travel path (1).
Claim 2
Dependent Claim
164 words
An inductive radio control system for performing data transmission by inductive radio means between traveling means (2) which travels along a travel path (1) formed in a predetermined route and ground operation control means (5) so as to control the travel of said traveling means (2) in response to a control signal (Sll) from said ground operation control means (5) and receive a monitor signal (S12), characterized by comprising: a plurality of loop antennas (8-1 to 8-n) arranged discretely along said travel path (1); transmitting/receiving means (140) for transmitting the travel control signal and the monitor signal to said traveling means, the number of said transmitting/receiving means being the same as the maximum number of operating traveling means; and selecting means (144, 145) for selectively coupling one of the loop antennas (8-1 to 8-n) with said traveling means (2) so as to perform data transmission by inductive radio means, said loop antennas (8-1 to 8-n) being arranged discretely along the predetermined travel path (1).
Claim 3
Dependent Claim
50 words
A system according to claim 1, characterized in that response data from said traveling means is checked every time communication between said traveling means and said transmitting/receiving means is established for data transmission, and another transmitting/receiving means among said transmitting/receiving means is selected when the response data is not received.
Claim 4
Dependent Claim
59 words
A system according to claim 1, characterized in that a carrier wave is checked by carrier wave detecting means arranged at a transmission side of said selecting means when communication between said traveling--means and said transmitting/receiving means is established for data transmission, and another transmitting/receiving means among said transmitting/receiving means is selected when the carrier wave is not detected.
Claim 5
Dependent Claim
30 words
A system according to claim 1, characterized in that the travel control signal and the monitor signal comprise a signal obtained by modulating the carrier wave with a tone signal.
Claim 6
Dependent Claim
31 words
A system according to claim 4, characterized in that the carrier wave which is not modulated with the tone signal is used as a stop control signal for the traveling means.
Claim 7
Dependent Claim
30 words
A system according to claim 5, characterized in that emergency loop antennas are arranged in route portions where said loop antennas are not arranged, thereby transmitting only the carrier wave.
