Integrated Management Of Computer Design And Development Of Multi-function Communication Board,

Army weapons and traditional items as military units participate in research, involving wide areas, the lack of uniform standards, requires a variety of different functions and interface boards to cope with different equipment, resulting in the system too complex, the volume increases, power increases to the limited space and power consumption brings many disadvantages of weapons systems. Interface too many, the connection complexity, security is not high, the Internet is difficult coordination, reduce the reliability, operational efficiency to become a bottleneck.Integrated management of the computer is antiaircraft systems information management center. Integrated management subsystem for antiaircraft operation management software, the information collection,processing,control,management and communications functions. Responsible for all gun control and management of the search target selection and validation of an attack, communications and liaison with the outside world. Automation technology is based weapons systems,their performance has an important impact on the weapon system. Because space is limited within their own artillery, thus requiring small size, integrated management of computers, low power consumption, high reliability, ease of quick repair.Integrated management of multi-function communication board is one of the core component of a computer is to connect the integrated management computer and the external other devices as a bridge, complete with the bus network and data exchange between devices, with bi-directional information processing capability, achieving bus communication network agreement is a comprehensive management computer and the intelligent interface node.This thesis is based on integrated management of multi-function communication board for the computer study, an integrated CAN communications, serial communication, signals and other functions when the system interfaces. Programmable logic device CPLD to control the timing and to achieve high-speed multi-channel data communication, enabling timely and effective transmission of information. And completed the +28 VDC to +5 VDC the power conversion circuit design. As the design of computer integrated management of multi-function communication board, is the weapon system automation, information technology key device, a strong real-time communication, we must work to ensure the reliability of the bus network, but also provided through GJB151A electromagnetic compatibility requirements. Therefore, the issue in-depth study of the reliability of multi-function communication board, interference and electromagnetic compatibility issues, and multi-function communication board for the reliability allocation, reliability prediction, reliability analysis and reliability evaluation. Through multi-function communication board functional simulation, functional testing, environmental stress screening, and environmental adaptability tests a number of tests, the multi-function communication board design is correct, its functionality and performance can meet the technical requirements, product reliability to meet development of the provisions of the general requirements, electromagnetic compatibility standards to achieve a military system.
