Abstract

FIELD: radiolocation, remote control systems, systems controlling air, water and ground transport, railway transport included. SUBSTANCE: method can also be used to control movement of cargo and live objects. It consists in transmission of wave signals to transmitter mounted on mobile object with the aid of transceiving facility, in reception of re-emitted signal, in determination of coordinates of mobile object and in sending information on them to receiving center. Information on coordinates of mobile object is transmitted in turn from one transceiving facility to another, nearest facility and then to receiving center.

Description

 The proposed method for determining the location of a moving object can be used in radar, remote control systems, control systems for the movement of air, water, ground, including railway transport, as well as cargo and living objects.

 A known method for determining the location of a moving object, selected as the closest analogue, which consists in the fact that a pulsed radio signal is emitted from a moving object, receive this signal at the reference station and transmit, encoding the re-emitted signal with a code unique to each reference station, receive the re-emitted signal at the observation point , process the received information and thereby determine the location of the moving object [1].

 The disadvantage of this method is that the device emitting a radio signal installed at the facility must have a power source.

 The technical problem of the proposed method is to increase reliability.

 The objective is achieved by the fact that in the method of determining the location of a moving object, which consists in supplying an encoded signal from a sensor installed on the object to the receiving and transmitting device and transmitting information to the receiving center, receiving and transmitting devices installed at previously known points, the sensor of the moving object gives a pulse under the influence of the wave signals of the emitter of the transmitting and receiving device, the receiving and transmitting device receives the signal from the sensor, processes it and transmits t to the receiving center information on the coordinates, speed and direction of movement of the moving object; each receiving and transmitting device has a zone of its action, receiving and transmitting devices have a spatial arrangement and can move along a known path.

 The proposed method is implemented using the circuits shown in figures 1 to 7.

 The circuits shown in figures 1 to 7 contain: a movable object 1 on which a sensor 2 is mounted, activated by the wave signal of the emitter 3 of the transmitting and receiving device 4, the receiving center 5.

 Figure 1 and 2 shows a diagram with the location of the transceiver at known points.

 The sensor 2 installed on the object 1, falling into the coverage area of the receiving-transmitting device 4, is activated by the action of a wave signal coming from the emitter 3, and transmits a response encoded signal to the device 4. The transmitting and receiving device 4, having received the encoded signal from the sensor 2, processes the signal and transmits information about the coordinates, speed and direction of movement of the object 1 to the adjacent (closest in distance) receiving and transmitting device 4, which, in turn, transmits information to the following receiving and transmitting device 4, and so on to the receiving center 5. As a result, the center 5 receives information about the coordinates, speed and direction of movement of the object 1, located in the coverage area of one particular receiving and transmitting device 4.

 In FIG. 3 shows a diagram with the location of the transmitting and receiving devices 4 along a predetermined path of the object 1. The sensor 2 installed on the object 1, falling into the coverage area of the receiving and transmitting device 4, is activated when a wave signal emanating from the emitter 3 is transmitted, and transmits to device 4 encoded signal. The transmitting and receiving device 4 processes the signal and transmits information about the coordinates, speed and direction of movement of the object 1, located in the zone of its operation, to the local network. Information is transmitted over the network to the receiving center 5.

 Figure 4, 5, 6, 7 shows a diagram with the location of the transmitting and receiving devices 4 at different levels of space. The sensor 2 installed on the object 1, falling into the coverage area of the receiving and transmitting device 4, is activated by the action of a wave signal coming from the emitter 3, and transmits an encoded signal to the device 4.

 In FIG. 4, 5, the receiving and transmitting device 4, having received the encoded signal from the sensor 2, transmits information about the coordinates, speed and direction of movement of the object 1, located in the zone of its action, to the neighboring (closest in distance) receiving and transmitting device 4. It, in in turn, transmits information to the receiving center 5.

 In FIG. 6, 7, the receiving-transmitting device 4, having received the encoded signal from the sensor 2, transmits information about the coordinates, speed and direction of movement of the object 1 directly to the receiving center 5. As a result, the center 5 receives information about the coordinates, speed and direction of movement of the object 1, located in the range of one specific transceiver 4.
