Embodiment 1

[0029] An embodiment of the present invention is an open radar health management system.

[0030] Aiming at the deficiencies of the existing technology, the present invention proposes an open radar health management system in combination with the characteristics of the existing radar, relying on the system architecture to realize the health management of the radar system, sub-systems, and modules, highlighting the hierarchical management.

[0031] According to the characteristics of radar equipment, the fault level is divided into I-IV level. Level IV (minor failure): This kind of failure is not enough to cause personal injury or system damage, but it will lead to unplanned maintenance, usually occurs in components, and has no effect on other modules; Level III (serious failure): Causes personnel to be slightly damaged Injury, certain economic loss, slight damage to the system, or delay or downgrade of the mission, usually with associated effects; Level II (fatal failure): a f...

Abstract

The invention discloses an open radar health management system, which belongs to the technical field of radar management. The invention includes: a front-end collection and processing unit and a back-end collection and processing unit, which are respectively used to collect the state monitoring data of the front-end and back-end components of the radar, and complete the fault with a fault hazard level of IV according to the preset diagnosis rules and evaluation rules Diagnosis and health evaluation; system management and guarantee unit, used to receive test instructions from the radar main console, complete board-level, sub-system, and system index tests, and combine test results from the front-end and back-end acquisition and processing units. Based on the obtained fault diagnosis and health evaluation results, the fault diagnosis and health evaluation of the fault hazard levels of III, II and I are completed according to the preset diagnosis rules and evaluation rules. The invention is applicable to various types of radars with complex systems and numerous devices, and realizes hierarchical management of the health of radar systems, sub-systems and modules.

Description

technical field [0001] The invention belongs to the technical field of radar management, and in particular relates to an open radar health management system. Background technique [0002] Radars in civil fields such as air traffic control and meteorology are increasingly using phased array systems, and the scale of equipment is getting larger and larger. The requirements for rapid fault location, system performance status analysis, and rapid support are getting higher and higher. Compared with traditional analog array radars, digital array radars are more complex in function and structure, so higher requirements are placed on the stability of equipment, the timeliness and effectiveness of diagnosis and maintenance capabilities. Due to the interleaving of analog and digital signals of digital array radar and the limitation of test interface, the traditional test and diagnosis mode mainly based on external test is difficult to achieve the goal of fast and accurate diagnosis. ...
