A Malfunction Example of the Digital Wireless Communications between a Certain Type of Command Vehicle and Reconnaissance Vehicle

Abstract

Digital wireless communications between a certain type of command vehicle and reconnaissance vehicle is an important communication way in such equipment, which includes digital cable mode, digital wireless mode and network communication, etc. It is known that digital cable and network communication have to be carried out by a covered wire connection in the process of communication, so it is perhaps feasible if two vehicles are close enough in relative static condition. However, it is impractical to pull and construct so long a covered wire for communication in real combat when the two vehicles maintains a far distance from each other, because if length of the wire is too long, the communication would break off once malfunction occurred in a whatever local part of wire. Moreover, it is very difficult for troubleshooting. At this time digital wireless communication is vital for battlefield communication between the two vehicles, and as long as we well define the default parameters before combat, then you can communicate directly during combat. Undoubtedly, the digital wireless communication has become the most important means of communication between such equipment. So we here provide an example of malfunction diagnosis and troubleshooting in such type of digital wireless communication equipment for basic technical officers.[1] 1 MALFUNCTIONPHENOMENON Open the command vehicle and the reconnaissance vehicle, operate a digital wireless communications network operation from initial step to final step to ensure that the process is definitely correct, and then get through the digital transmission and voice communication, but it comes out to find that both of communication ways fail and do not work at all. 2 MALFUNCTIONDIAGNOSIS The main connection structure for wireless communication between command vehicle and reconnaissance vehicle is shown in Fig.1.
