Abstract
Abstract An infra-red transmission system in which messages in the form of pulse coded data signals are transmitted between transmitting-receiving units (6) each being provided with at least one or a plurality of infra-red light emitting elements and one or a plurality of infra-red light sensitive photo-element, in a house having such a formed, common outlet and inlet opening for the infra-red light, that a directed transmitting and receiving beam is obtained. The message transmission is used for the control of carrier movements destined for the transport of goods along movements paths in an area, a plurality of transmitting-receiving units (6) being mounted on fixed locations along the movement paths and one transmitting-receiving unit (6) being mounted on each carrier (12) all having such an alignment of the transmitting-receiving beams that when a carrier passes said locations the relevant transmitting-receiving beams sweep across each other during which the message transmission takes place. In each carrier (12) which is freely controllable in direction and speed a data input- and display unit, connected to the associated transmitting-receiving unit, is mounted in aid of the driver.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
214 words
An infra-red transmission system in which messages-in the form of pulse coded data signals are transmitted between transmitting-receiving units each being provided with at least one infra-red light emitting element and one infra-red light sensitive photo-element, the message transmission being used for the control of carrier movements destined for the transport of goods along movements paths in an area, for which purpose on each carrier such a transmitting-receiving unit and in said area at least one such a transmitting-receiving unit is installed, characterized in that each transmitting-receiving unit having the infra-red light elemitting element(s) and the infra-red light sensitive photo-element(s) is taken up in a house having such a formed, common outlet and inlet opening for the infra-red light, that a directed transmitting and receiving beam is obtained, that a plurality of transmitting-receiving units is mounted on fixed locations along the. movement paths and said one transmitting-receiving unit is mounted on each carrier all having such an alignment of the transmitting-receiving beams that when a carrier passes said locations the relevant transmitting-receiving beams sweep across each other during which the message transmission takes place, whereby in each carrier being freely controllable in direction and speed, a data input- and display unit, connected to the associated transmitting-receiving unit, is mounted in aid of the driver.
Claim 2
Dependent Claim
214 words
An infra-red transmission system in which messages-in the form of pulse coded data signals are transmitted between transmitting-receiving units each being provided with at least one infra-red light emitting element and one infra-red light sensitive photo-element, the message transmission being used for the control of carrier movements destined for the transport of goods along movements paths in an area, for which purpose on each carrier such a transmitting-receiving unit and in said area at least one such a transmitting-receiving unit is installed, characterized in that each transmitting-receiving unit having the infra-red light elemitting element(s) and the infra-red light sensitive photo-element(s) is taken up in a house having such a formed, common outlet and inlet opening for the infra-red light, that a directed transmitting and receiving beam is obtained, that a plurality of transmitting-receiving units is mounted on fixed locations along the. movement paths and said one transmitting-receiving unit is mounted on each carrier all having such an alignment of the transmitting-receiving beams that when a carrier passes said locations the relevant transmitting-receiving beams sweep across each other during which the message transmission takes place, whereby in each carrier being freely controllable in direction and speed, a data input- and display unit, connected to the associated transmitting-receiving unit, is mounted in aid of the driver.
Claim 3
Dependent Claim
60 words
An infra-red transmission system according to claim 1, characterized in that the plurality of fixedly mounted transmitting-receiving units is installed in the road surface of the movement paths, the associated transmitting-receiving beams being directed upwards, and that each carrier is provided with a horizontal support arm to which said one transmitting-receiving unit is fastened having its transmitting-receiving beam directed downwards.
Claim 4
Dependent Claim
71 words
An infra-red transmission system according to one of the preceding claims, characterized in that the transmission speed of the message signals, the radius of the transmitting-receiving beam of the transmitting-receiving units, and the speed of the carriers are matched such to each other that a complete message exchange between the transmitting-receiving unit of the carrier and the surface road based transmitting-receiving unit is guaranteed during a usual movement of the carrier.
Claim 5
Dependent Claim
35 words
An infra-red transmission system according to claim 3, characterized in that the transmission speed, the radius of the transmitting-receiving beam, the speed of the carrier respectively amount to 100.000 bit/sec, 3-5 meter and 18-36 km/hour.
Claim 6
Dependent Claim
51 words
An infra-red transmission system according to one of the preceding claims to be used in a storage and throughput area for the movement of containers and such goods by means of freely controllable transport carriers, the drivers of which receive, carry out and report movement instructions via the infra-red transmission system.
