specific Embodiment approach 1

[0023] Specific implementation mode 1. Combination Figure 1 to Figure 6 In this embodiment, the automatic test system for the UAV cable network is mainly composed of a host computer, a controller and an electrical connector interface adapter. The upper computer is connected with the controller through the RS422 interface, and the controller is connected with the electrical connector interface adapter through the I / O interface; the controller is mainly composed of an information processing module and an electrical connector pin level reading and writing module. The information processing module is composed of CPU, SRAM, FLASH and RS422 controller. FLASH solidifies the embedded application program, and after the system is powered on, the solidification program is guided to run in the SRAM under the control of the CPU. Runtime programs and data are stored in SRAM. The CPU in the information processing module receives information from the upper computer through the RS422 contro...

specific Embodiment approach 2

[0030] Specific embodiment two, this embodiment is the testing method of the UAV cable network automatic test system described in specific embodiment one, and this method is realized by the following steps:

[0031] 1. Run the cable network automatic test system software on the host computer;

[0032] 2. Input the tested cable network wiring table into the database of the cable network automatic test software, the tested cable network wiring table includes the connection relationship between the cables in the tested cable network;

[0033] 3. The cable network automatic test software automatically generates the target netlist file based on the input of the tested cable network wiring table, and loads the target netlist file to the controller through the RS422 interface;

[0034] 4. The information processing module in the controller first sends a logic high level to the first electrical connector pin level processing unit, and the high level is latched by the output latch and ...

Abstract

An automatic test system and a test method for an unmanned aerial vehicle cable network relate to the field of measurement and automation. The system is mainly composed of host computer, controller and electrical connector interface adapter. The upper computer is connected with the controller through the RS422 interface, and the controller is connected with the electrical connector interface adapter through the I / O interface. The upper computer runs the cable network automatic test software, and the automatic test software automatically generates the target netlist file according to the cable network wiring table input by the operator, and loads the target netlist file to the controller through the RS422 interface, and the controller passes through the electrical connector The interface adapter sends a logic level to the cable network under test and reads it back. Through the read logic level value, the on-off relationship between any two wires in the cable network can be measured, and the on-off relationship is sorted out and generated. Measuring the netlist file and comparing it with the target netlist file can detect and locate cable network faults. The invention can detect accurately and quickly, and save a lot of time and human resources.

Description

technical field [0001] The invention relates to the field of measurement and automation, in particular to an automatic test system and a test method for an unmanned aerial vehicle cable network. Background technique [0002] The UAV cable network is installed inside the UAV to connect the power interface, communication interface and control interface of all avionics systems of the UAV. It is an important part of the UAV. [0003] At present, the testing work of UAV cable network is mainly done manually. Because the size of the UAV cable network is related to the UAV body, the greater the take-off weight of the UAV, the more complex the onboard avionics equipment, and the larger the size of the cable network. drone, and its supporting cable network also needs to be tested in batches. Therefore, the test workload of the drone cable network is very large, requiring a lot of manpower and time. In addition, the cable network testing process is a repetitive mechanical labor. Aft...
