Technical Field

The utility model relates to a signal extraction and testing technology field, in particular to a self-propelled artillery equipment signal extraction test equipment.

Background Art

The current model of self-propelled artillery forces since a large amount of equipment, a large number of the equipment with high technical content, technology is continuously applied to a novel go weapons and equipment. As the information age symbolic product signal, also in the new self-propelled artillery equipment has been widely applied.

Furthermore, in the equipment maintenance process, the extraction of signals, detection must be a very important aspect, the determination of the fault point judging of the failure type and these core issues. Therefore, whether or not an impact on normal operation of the equipment, and in security and stability of the system of a large number of state signal is extracted, is equipped with detection, the core of the maintenance.

In view of this reason, the item is "signal extraction" to the key issues to a bold. In the past, we can only be based on fault diagnosis of the failure phenomenon that the fault point. Of course, for the old equipped with this kind of method has been enough, because of low technical content of the old equipment, the structure is relatively simple, few kinds of failure, therefore, by a simple determination can basically determined according to the fault point failure phenomenon. However, today's equipment greatly improving the technical content, hundreds of thousands of electronic components of the system function is increased at the same time also increases the complexity of the system. In this way, the difficulty of the fault reason increased number, if according to the failure phenomenon, has apparently can not be accurately and quickly determine the fault point. We need more information on the status of the system in order to find the fault point detecting and maintenance. In this case, on the input of critical components needed to be extracted, the state signal of the output and, used for assisting to judge whether the fault cause.
