Abstract
The invention concerns a data transmission method, and its implementing device, in an integrated closed system of computers, such as, for example, in an aerial or land vehicle, comprising a step which consists in transmitting point-to-point data between two transmission nodes, for example via a wire system, each node having one or more channels enabling each transmission with a single node, a step which consists in converting data for transmission thereof, for example, in series. The invention is characterized in that it does not comprise any step of physical or logical control for authorizing and/or validating the transmitted data so that any data reception at a node is unconditionally followed by a retransmission, that is the control of the dataflows is implicitly determined by the cabled topology used.
Claims20
A method of transmitting data in a closed on-board control computer system, such as for example in an aircraft or land vehicle, comprising a step of transmitting data point to point between two transmission nodes, for example via a cabled network, each node having one or more channels each allowing transmission with a single node, a step of converting data for transmission thereof, for example in series, the method comprising no physical or logic control step for the authorisation and/or validation of the data transmitted so that any reception of data at a node is followed unconditionally by a retransmission, that is to say the control of the data flow is determined implicitly by the cabled topology used.
A data transmission system, comprising:
- a data transmission medium;
- at least two transmission nodes operably connected to said transmission medium, wherein each of said nodes has one or more channels each allowing transmission with a single node;
- and
- a control computer operably connected to said transmission medium wherein said control computer operably transmits data point to point between said two transmission nodes and converts data for transmission thereof, and wherein said control computer performs no physical or logical control for authorisation and/or validation of the data transmitted, thereby ensuring that any reception of data at a node is followed unconditionally by a retransmission, and that control of flow of the data is determined implicitly by a connection topology of a network formed of said nodes and said transmission medium.
A vehicle, comprising:
- a point to point network in place of a vehicle bus, the network including:
- (a) a data transmission medium;
- and
- (b) at least two transmission nodes operably connected to said transmission medium, wherein each of said nodes has one or more channels each allowing transmission with a single node;
- and
- (c) a control computer operably connected to said transmission medium, wherein said control computer operably transmits data, including the sensory data and the control data, point to point between said two transmission nodes and converts data for transmission thereof, and wherein said control computer performs no physical or logical control for authorisation and/or validation of the data transmitted, thereby ensuring that any reception of the data at one of said nodes is followed unconditionally by a retransmission, and that control of flow of the data is determined implicitly by a connection topology of said point to point network,
- at least one actuator in communication with at least one of said nodes of said point to point network and operably connected to control operation of a component of said vehicle;
- at least one sensor in communication with at least one of said nodes of said network and operably connected to sense one or more conditions relating to operation of said vehicle.
