In order to realize the performance testing and fault diagnosis of communication devices in the Command and Control System, a testing system is proposed. In this paper, a novel communication protocol is developed to realize the communication between the host computer and lower computer of the testing system. As to the different functions of the testing system, the format and sense of the communication messages were introduced in detail. 15 kinds of messages were designed to complete the functions of the open and close of communication serial, data detection ports, the receive and transmission of detection data, the control of the I/O and so on. The communication protocol makes it possible to form the test path and achieve the test of different devices.
With the advent of the information age, the theory of network-centric operations come into beings. Network and network devices constitute the core of the C3I system which is the cornerstone of the network-centric operations. However, it is difficult to maintenance and support the C3I network devices for the reason of its specific features, such as its all kinds of models, wide geographical distribution, complex structure, highly reliability requirements and so on [. we propose a network device monitoring method to improve network equipment running reliability, real-time fault detection and save the utilization of network resources based on the existing method.
C3I network equipments, with complex architecture, deal with quantities of information from the aspect of time and space, which makes them difficult to support. This paper adopts automatic test and diagnosis techniques, analog networking technique and active test method to satisfy the requirements of timeliness, intelligence and high precision in fault location. A virtual network environment is built to complete the network equipments’ test. It is significant to the complex network equipments’ test and diagnosis.
For the purpose of solving the problems, such as many kinds of C3I equipment signals to be test, complicated technology and technology fast updates, a test system based on flexible technology is proposed. In this system, the core technical cocept of systematize and developmental design is adopt. In this paper, the design ideas, software and hardware design and test diagnosis process are described in detail. The detection system based on flexible test achieves calling testing resources according to the different objects, interfaces conversion and signal conditioning. The system has good characteristics on flexibility, reliability, adaptability and expand [1-, which is of great significance for the equipment maintenance and support.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
