Bus Interface Questions
Based On Field Bus Technology Transfer Program Of The Signal
Introduction This stage, the system used to implement the relevant components of the design of signal transmission in most of the simple point to point wire-type transmission, such transmission in the case of less number of signals can be said is a simple and practical way, but much against the number of signals and the limited space, this design approach appears to be somewhat awkward, for example, the number of signals as much lead connectors, wire increases, so does not only control of a Missile Fuze System Design lot of pressure also because of the use of a large number of connectors reduce signal transmission system reliability, but also because of the presence of a large number of wires reduce the system adaptability to environment and electromagnetic compatibility.
Fuse with a missile control system design technology, the functional requirements of more complex, and miniaturization and reliability of its structure, Security Requirements and other performance indicators continued to improve, the traditional point-wire type signal transmission increasingly unable to meet the development requirements of the system, with the drawbacks of the traditional design of the highlights signaling and digital control technology and network Communicate The technology matures, a new type of field bus transmission scheme designers more and more attention to the fieldbus as the core design of the signal transmission can effectively point to overcome the traditional drawbacks of wire-type transmission, improve Signal transmission system performance.
1 program design principles System, signal transmission between the relevant components of the implementation is essential for the realization of a system function, so, in the research and design process to ensure the system works all the signal transmission process real-time, reliable [1]. Specific design principles can be summarized as follows:
A) the principle of succession: a reasonable draw and design in the tradition mature and rational design experience, and for the new scheme of signal transmission systems, to highlight the design, reduce design cycles, improve efficiency, save money .
B) advanced principle: Fieldbus program itself is relatively conventional design of a major breakthrough, so the system signal transmission in the study and design process should focus on future needs, based on mature technologies as much as possible the use of advanced methods and products to optimize the hardware and consider the flexible and efficient high-speed communication protocols.
C) the principles of reliability, new field bus program, bringing the one hand, Cable Simplified, helping improve the reliability, on the other hand because of the increased bus interface and self-detection tasks, the system of local complexity increased, while the shells on the work environment is more severe, are likely to form a new fault risk, so the scene Bus selection is important to note the balance of performance and reliability considerations, so that rational design.
D) the principle of flexibility: the control system components are many different functions, signal properties vary greatly in the research and design program should be in accordance with their characteristics and needs of the general features, flexible configuration using the combination of bus and green way of rational design.
E) the principle of redundancy: redundancy is the traditional signaling the importance of experience in the design process is the basic principle of the bus program, rational use of redundant design will not only improve the reliability of bus system, but also to improve the system performance.
2 Preliminary Design and Implementation of the program
According to IEC standards and the Fieldbus Foundation (FF) of the definition, field bus is an all-digital, serial, two-way communication system, through the system Sensor , Actuators and controllers to connect field devices, therefore, can be used in all components of complex systems, “intelligent” to truly create a decentralized communications network site.
Following control system for a missile fuze system, the signal characteristics and functions of all related components to achieve the requirements of the program’s design principles based on its signal transmission preliminary research and analysis program.
2.1 Fieldbus Selection On FF, LonWorks, Profibus, CAN, HART and other characteristics of different types of field bus analysis and comparison is found, CAN bus is the most numerous fieldbus application of a future. CAN supports multi-way principal point of work, any node on the network can be active at any time send information to other nodes in support of point to point, multipoint, and global Broadcasting To receive and send data. Its main advantages are: multi-master bus structure; wiring simple and most Qualcomm Letter rate up to 1Mbit / s; CAN protocol to encode the digital communications module; CAN bus ensures a low error rate data communication reliability.
Fuse in the control system of a missile control and Test Requirements analysis that, CAN bus control system fully satisfy the reliability and real-time requirements. However, in bus data throughput to the deficiencies, which were designed to consider the system through the control channel and test channel, or can be configured by type of field bus, such as Profibus, etc., to accommodate the different needs of control and testing.
2.2 interface design based on field bus
Fieldbus interface with a control system before the missile fuze systems and ground-based monitoring system after system and signal transmission between the need for hardware and software research and design.
2.2.1 Hardware Design First of all, to be connected to determine the relevant components of the system, parts of the detection signal and the number of control signals, types, and signal characteristics. As the system transfers the relevant subsystems Electric Signals were many types can be classified according to Power supply Line, the system control signal lines, system test signal line. In order to meet overall system needs, to try to optimize the design of signal transmission system, in theory, these signals through suitable transformations can be transferred through the bus, while the actual design should be based on all relevant components and parts functions, signal types to consider the importance of rational design requirements. The program is considered the main bus network in combination with a small number of dedicated connections for signal transmission design ideas, such as power supply signals, self-destruct signal, Battery Activation signals. Specific connection relationship shown in Figure 1.
Second, be connected to the system according to the relevant components, parts, select the appropriate controller and the bus adapter pieces, shown in Figure 1, the “communication module”
