Description

Technical Field

[0002] Both aircraft and automobiles are combinations of complex systems. The performance of modern aircraft airborne electronic equipment is becoming more and more advanced, resulting in the increasing complexity of airborne electronic equipment, more and more ground test detection items, and a growing workload. With the increasing trend of aircraft maintenance towards intelligence and rapidity, if the detection work is not in place, it will lead to the failure of airborne electronic equipment to achieve the expected effect, and in severe cases, it will even affect the normal use of airborne electronic equipment. The performance of modern automobiles is also becoming more and more advanced, resulting in more and more items to be detected and a growing workload. Thus, it can be seen that since aircraft and automobiles often have multiple systems intersecting with each other, and each system is controlled by a single or multiple finished products. In the traditional production method, after the whole machine or partial assembly is completed, the entire system is verified through the cockpit to confirm the correctness of its installation and the integrity of the finished products. If the system and the finished products are intact, this verification method saves time and effort. However, when problems occur in the system and the finished products, the assembled system needs to be disassembled and reassembled for verification, which is time-consuming and laborious, and will affect the production cycle.

[0003] For different required voltages and currents, the finished products can be tested and debugged before being installed in the machine, exposing the problematic finished products in advance and reducing the rework rate of finished product problems to zero. It can ensure the integrity of the finished products before they are assembled into the aircraft or automobile, so it is very necessary to provide a multi-functional general debugging equipment. After retrieval, the patent document with the authorization announcement number CN211744011U discloses a multi-functional thermal automation on-site debugging equipment, the patent document with the authorization announcement number CN208353755U discloses a multi-functional power debugging device, and the patent document with the authorization announcement number CN216721776U discloses a multi-functional power debugging device. From the content disclosed in the three retrieved patent documents, a debugging device that meets the usage requirements is provided from different perspectives. Therefore, in order to meet the test requirements for voltages or currents of different systems or finished products, so as to cooperate to complete a large number of production tasks, a debugging device different from the prior art is designed and applied in the aircraft or automobile production process, which can meet the debugging and detection requirements of multiple different system or finished product models, and ensure that each installed system is correct and intact, so as to ensure the correctness of the installation of all systems before docking with the cockpit.
