Abstract

Abstract Train monitoring equipment for a train formed by coupling a plurality of sets of cars of fixed formations, comprising monitoring stations mounted in the respective cars of the train and connected serially by transmission lines. Presetting switches are provided in the respective monitoring stations for presetting the formation numbers of the sets of cars in which the respective monitoring stations are located. One of the monitoring stations which serves as the control station transmits its formation number to the other monitoring stations which then register their station numbers on the basis of conformity or non-conformity of the preset formation numbers with the received formation numbers.

Train monitoring equipment for a train including a first set of cars and a second set of cars, said first and second set of cars comprising respectively a plurality of cars coupled together, wherein the cars of said first set have a first formation number and the cars of said second set have a second formation number different from said first formation number, said train monitoring equipment comprising: monitoring stations which are respectively mounted in each of said cars and each of which registers the number representing the location of the corresponding car; transmission lines for connecting said monitoring stations serially; and formation number presetting means for presetting said first formation number in said first set of cars and said second formation number in said second set of cars for discriminating between said first and second sets of cars.
Claim 3
Dependent Claim 191 words
Train monitoring equipment for a train including a first set of cars, a second set of cars and a third set of cars, said first set of cars having a first formation number, said second set of cars having a second formation number different from said first formation number, and said third set of cars having a third formation number different from said first and second formation numbers, said train monitoring equipment comprising: monitoring stations which are respectively mounted to each of said cars and each of which registers the number representing the location of the corresponding car; transmission lines for connecting said monitoring stations serially; formation number presetting means for presetting said first formation number in said first set of cars, said second formation number in said second set of cars, and said third formation number in said third set of cars for discriminating between said first, second and third sets of cars; and input means for providing the two monitoring stations mounted in the leading and the rear cars of said train with information indicating that said two monitoring stations are respectively located at the ends of said train.
Claim 4
Dependent Claim 191 words
Train monitoring equipment for a train including a first set of cars, a second set of cars and a third set of cars, said first set of cars having a first formation number, said second set of cars having a second formation number different from said first formation number, and said third set of cars having a third formation number different from said first and second formation numbers, said train monitoring equipment comprising: monitoring stations which are respectively mounted to each of said cars and each of which registers the number representing the location of the corresponding car; transmission lines for connecting said monitoring stations serially; formation number presetting means for presetting said first formation number in said first set of cars, said second formation number in said second set of cars, and said third formation number in said third set of cars for discriminating between said first, second and third sets of cars; and input means for providing the two monitoring stations mounted in the leading and the rear cars of said train with information indicating that said two monitoring stations are respectively located at the ends of said train.
Claim 5
Dependent Claim 26 words
Train monitoring equipment according to claim 1 or 2 wherein said formation number presetting means are preset switches which are respectively provided in each monitoring station.
Claim 6
Dependent Claim 31 words
Train monitoring equipment according to claim 1 or 2 wherein said formation number presetting means are selectively short-circuited pins of connectors used for connecting said monitoring stations to the corresponding cars.
Claim 7
Dependent Claim 32 words
Train monitoring equipment according to claim 1 or 2 wherein said formation number presetting means are means capable of deriving the formation numbers from the car numbers assigned to the respective cars.
Claim 8
Dependent Claim 209 words
Train monitoring equipment for a train comprising a plurality of sets of cars of fixed formations coupled together, each of said sets of cars having a formation number and a plurality of cars, each of said formation numbers being different from one another, said train monitoring equipment comprising: monitoring stations which are respectively mounted in each of said cars and each having a registered number representing the location of the corresponding car in the fixed formation; formation number presetting means for presetting in said monitoring stations of each of said sets of cars, said formation number corresponding to the set of cars to which the respective monitoring stations belong; and transmission lines for connecting said monitoring stations serially; wherein one of said monitoring stations serves as the control station and transmits to said monitoring stations information concerning at least the formation number of the set of cars to which the control station belongs, and wherein said monitoring stations receive said information from the control station and register station numbers thereon on the basis of the formation numbers preset by said formation number presetting means and the formation number derived from the received information, thereby enabling said control station to identify the location of said monitoring stations in said train.
Claim 9
Dependent Claim 209 words
Train monitoring equipment for a train comprising a plurality of sets of cars of fixed formations coupled together, each of said sets of cars having a formation number and a plurality of cars, each of said formation numbers being different from one another, said train monitoring equipment comprising: monitoring stations which are respectively mounted in each of said cars and each having a registered number representing the location of the corresponding car in the fixed formation; formation number presetting means for presetting in said monitoring stations of each of said sets of cars, said formation number corresponding to the set of cars to which the respective monitoring stations belong; and transmission lines for connecting said monitoring stations serially; wherein one of said monitoring stations serves as the control station and transmits to said monitoring stations information concerning at least the formation number of the set of cars to which the control station belongs, and wherein said monitoring stations receive said information from the control station and register station numbers thereon on the basis of the formation numbers preset by said formation number presetting means and the formation number derived from the received information, thereby enabling said control station to identify the location of said monitoring stations in said train.
Claim 10
Dependent Claim 105 words
Train monitoring equipment according to claim 6, wherein said train comprises two sets of cars of fixed formations coupled together, wherein the monitoring station mounted in the leading car of said train serves as the control station and transmits to said monitoring stations information concerning the direction of running of said train and the formation number of the set of cars to which the control station belongs, and wherein said monitoring stations receive said information and register station numbers therein on the basis of the direction-of-running information and conformity or non-conformity of the preset information numbers with the formation number derived from the received information.
