The disclosure relates to communication technology, more particularly to a method and a device for bus addressing and a method and a device for providing information.
High speed serial bus is a standard computer peripheral bus having advantages such as hot plugging, high performance and low system cost. High speed serial bus is widely used in control systems of automatic control, aviation, aerospace, navigation and unmanned aerial vehicle.

Technical solutions of embodiments of the disclosure will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that, the drawings merely illustrate some embodiments of the disclosure, and other drawings can be conceived without any inventive effort.
A better understanding of the disclosure will be obtained by reference to the following detailed description that sets forth illustrative embodiments with reference to the drawings.
A method for bus addressing in accordance with a first aspect of the disclosure will be described.
In step 101, a process can be performed in which a controller can receive handshaking information from a component of a control system.
In step 102, a process can be performed in which the controller can allocate a communication address to the component through a field bus and establish a correlation between a physical address and the communication address of the component.
It will be appreciated that, a field of application and a type of the control system are not limited, and a function and a type of the components of the control system are not limited.
In some embodiments, the component of the control system can first send handshaking information to the controller. Upon receiving the handshaking information, the controller can allocate a communication address to the component and establish a correlation between a physical address and the communication address of the component, such that the component is provided with a unique communication address. The component can thus perform an information interaction with other components of the control system and perform an information interaction with the controller, ensuring a normal communication of components in the system. A maintenance personnel can determine the physical address of the component from the communication address based on the correlation between the physical address and the communication address of the component established by the controller, making it convenient for subsequent maintenance.
From the method shown in
In some instances, the index number can comprise a number, a letter or a combination thereof. A format of the index number is not limited in the disclosure.
In the alternative technical solution, a correlation between the physical address, the communication address and the index number can be established by the controller. The maintenance personnel can determine a type of the component based on the index number and then position the component based on the communication address and the physical address, such that a maintenance efficiency can be improved.
From the alternative solution as discussed hereinabove, the inventor further contemplates a situation where redundant components of the same type can be provided of the control system. An alternative technical solution is proposed by the inventor where an additional step is performed by the alternative solution as discussed hereinabove. In the additional step, a process can be performed in which the controller allocates different index numbers to the redundant components of the same type through the field bus if the control system comprises redundant components of the same type.
The redundant components can be two or more identical components of the control system, one of the two or more identical components being the redundant component of another. The user cannot distinguish the redundant components as they are provided with the same type, name and performance. Therefore, difference index numbers can be allocated to the redundant components of the same type. In some instances, however, an identical index number can be allocated to components of different types as the user can distinguish the components by referring to a component type even if the index numbers are identical.
In the alternative technical solution as discussed hereinabove, the controller can allocate different index numbers to redundant components of the same type. The maintenance personnel can identify a component based on the component type and the index number and then position the component based on the correlation between the communication address and the physical address, such that a maintenance efficiency can be improved.
In some instances, in order to further improve the user experience, the disclosure provides an alternative technical solution where a further step is performed by the method shown in
In the alternative technical solution, an interface for configuration can to provided to the user. The user can configure the index number of the component according to his/her own preferences, such that the user can clearly understand the index number of the component to further improve the user experience.
On basis of the method shown in
In step 201, a process can be performed in which a controller receives handshaking information from a component of a control system.
In step 202, a process can be performed in which the controller allocates a Controller Area Network Identification (CANID) to the component through a field bus and establishes a correlation between a physical address and the CANID of the component, the CANID being a communication address of the component in a CAN communication bus.
The CAN field bus is a content-oriented addressing solution, therefore a control system can be established with a high performance and flexibility. A new node can be added to the CAN bus without modifying the hardware or software configuration. The CANID can be used to effect an arbitration in the CAN bus. A lower ID value can indicate a higher priority of a message sent from a node. In case two messages are sent simultaneously from nodes having different ID values, the arbitration mechanism can enable a node having a lower ID value to take control and occupy the bus and thus successfully send out a message while a node having a higher ID value can exit. The ID domain can comprise 11 bits or 29 bits. The ID value and a meaning of the ID can be predefined by the user as a CAN high-layer protocol management. In some instances, the ID can further function to effect a message filtering of a receiver. For instance, the receiver can set a range of ID from which messages can be accepted, such that the receiver can filter out unnecessary information to reduce a processing burden of the central processor.
