Description
Technical field
The invention belongs to the weapon system information communications fields, in particular to intelligent cannon Tower System big data quantity, high real-time
Information data interaction with transmission artillery system information transmission link interface.
Background technique
Cannon technology is one of the dominant technology in conventional weapon, forward direction automation, autonomy-oriented and intelligent direction development.
In order to meet the development trend of Modern Gun, needs to increase mass data content in traditional cannon data information, improve data
Transmission rate.The information transmission of tradition cannon mostly uses the field bus techniques such as serial ports, CAN bus at present, these conventional informations
Transmission technology there are transmission rates low, poor reliability disadvantage.In practical applications in order to solve the bottle in information data transmission
Neck is typically only capable to solve by way of increasing transmission link quantity merely, this just causes system wiring again, and structure is complicated.This is just
It needs not only meeting system big data quantity, high real-time information data transmission, but also meets the requirement that system structure simplifies.It is former
Some conventional information transmission link technologies have been unable to satisfy the performance requirement of Modern weapon system.
Summary of the invention
The object of the invention is to provide a kind of fire to overcome the shortcomings of information transmission link technology in existing cannon
Gun system information transmission link interface.The information transmission link interface can simplify information transmission link structure, reduce system
Greatly increase the bandwidth of system transmission link while wire structures complexity, shortens the information period and accelerate transmission speed
Rate.
Artillery system information transmission link interface according to the present invention, by high-speed data information transmission link, low speed number
It is believed that breath transmission link, network Hub, photoelectricity rotary connector, photoelectric conversion device constitute: high-speed data information transmission link by
Real-time industrial ethernet composition based on PowerLink technology, is used for transmission in artillery system high speed relevant to system control
Real-time periodic data；Low speed data information transmission link is made of CAN bus, is used for transmission status data in artillery system
And low speed random data relevant to operational order；Network Hub is for each node connection of high-speed data information transmission link；Photoelectricity
Rotary connector is connected for filling the cable between lower dress on weapon system；Photoelectric conversion device is by high-speed data information chain
The electric signal on road is converted into optical signal, passes through photoelectricity rotary connector for high number data information transfer link.
Artillery system information transmission link interface according to the present invention had both met system big data quantity, high real-time letter
Data transmission is ceased, while meeting the requirement that system structure simplifies again.
Detailed description of the invention
Fig. 1 is structural schematic block diagram of the invention；
Specific embodiment
With reference to the accompanying drawings and examples, the present invention is further described.
Embodiment
The present embodiment is application example of the present invention in intelligent gun turret project, and structure is as shown in Figure 1.Artillery system letter
Ceasing in transmission link includes an Industrial Ethernet link for the transmission of high-speed data information, and one is used for low speed data information
The CAN bus link of transmission adds photoelectricity rotary connector and photoelectric conversion device.Each node passes through the letter divided when design
Type is ceased, the information that selection needs to send is sent especially by which link.
Steps are as follows for concrete methods of realizing:
1, high-speed data information transmission link designs
(1) network parameter of system high-speed data transmission link is configured
At the beginning of the transmission of system high-speed data, needing first to configure transmission cycle is 20 milliseconds, and transmission mode is cross-communication
The data such as the node number of mode and each node transmit relevant network parameter, guarantee that whole link works normally.
(2) needs that each node in system is respectively configured receive the data content sent
According to the entire intelligent cannon Tower System data content that defined each node needs to send and receive in design, need
Each node is configured, guarantee that each node can receive the data needed for operating normally, other nodes are not
The data needed will not be received, and guarantee the working efficiency of system.
(3) timeslice that each node data is sent is set
According to factors such as the working characteristics of node each in intelligent cannon Tower System and the renewal times for sending data, rationally it is arranged
The timeslice that each node data is sent.Timeslice setting should guarantee the real-time that each node data updates, and consider communication again
Other node data sending instants of chain road, avoid traffic congestion on information transmission link.
2, low speed data information transmission link designs
(1) each node CAN bus messaging parameter is set
Each node CAN interface will configure interface before enabling, and the operating mode that the node is arranged is
Normal mode, baud rate are 500K and receive the messaging parameters such as mask off code, it is ensured that normal communication between each node.
(2) corresponding data ID is compiled and edit to each information in system
Information communication protocol when being designed according to weapon system works out the extension frame data for needing to communicate in CAN bus
ID guarantees that the node that it can be required receives, and the node that do not need can not then receive.
The present invention in practical applications, can also carry out Redundancy Design to a link according to actual needs.Such as to high-speed data
Information transmission link takes how main redundancy, double-network redundant, ring redundancy etc. to design；Low speed data information transmission link is taken double
The design methods such as road redundancy.The fault-tolerant ability under the extreme case of entire weapon system is improved, guarantees system data information transmission
Reliability.
