specific Embodiment approach 1

[0018] Specific implementation mode 1. Combination figure 1 Describe this embodiment, the portable multi-channel electric steering gear auxiliary test system, including DSP controller, DIP switch, AD acquisition module, DA output module, encoder and monitoring equipment;

[0019] In this embodiment, digital signal sources and analog signal sources are used as steering gear instructions, and the dial switch is adjusted according to test requirements to select digital signal sources or analog signal sources. If it is an analog signal source, then open the AD acquisition module and the DA output module. The analog signal is collected and filtered, and the digital signal fed back by the steering gear to be tested is converted into an analog signal output through the DA output module. If it is a digital signal, the DSP internal generation command is used; and then according to the communication protocol of the steering gear to be tested, adjust The dial switch sets the communicatio...

specific Embodiment approach 2

[0023] Embodiment 2. This embodiment is the test method of the portable multi-channel electric steering gear auxiliary test system described in Embodiment 1. The method is realized by the following steps:

[0024] 1. First, you need to select the analog signal source by adjusting the DIP switch, select the single-channel servo to be tested, and select the communication method and command cycle according to the requirements of the servo;

[0025] 2. Connect the output port of the spectrum analyzer to the AD acquisition port of the device, and connect the input port of the spectrum analyzer to the DA output port of the system;

[0026] 3. Connect the communication port of the steering gear, the communication port of the upper computer, and the communication port of the monitoring device to the RS422 interface or the CAN bus interface of the system;

[0027] 4. Connect the input shaft of the external encoder to the output shaft of the steering gear, and the output line of the enc...

Abstract

The invention relates to a portable multichannel electric steering engine auxiliary test system and test method. The portable multichannel electric steering engine auxiliary test system and test method can solve the problem that an existing testing device for an electric steering engine is complicated in structure, is relatively large in volume, is relatively high in cost and is not convenient to carry, and the testing device cannot comprehensively test a digital steering engine. The portable multichannel electric steering engine auxiliary test system includes a DSP controller, a dial switch, an AD acquisition module, a DA output module and a monitoring device, wherein the dial switch selects an analog signal source; the DSP controller acquires external analog signals through the AD acquisition module; the AD acquisition module converts the external analog signals and then transmit the external analog signals to a steering engine to be tested; and the DSP controller receives a digital signal fed back from the steering engine to be tested, and transmits the digital signal to the monitoring device after decoding the digital signal fed back from the steering engine to be tested, and at the same time converts the digital signal fed back from the steering engine into an analog signal through the DA output module and outputs the analog signal to a frequency spectrum analyzer to realize frequency characteristic analysis for the steering engine to be tested.

Description

technical field [0001] The invention relates to a portable multi-channel electric steering gear auxiliary testing system and testing method. Background technique [0002] The electric steering gear is an important executive mechanism of the aircraft, and the performance of the steering gear system plays a very critical role in the normal operation of the entire flight control system. Therefore, in order to ensure the safety and reliability of the system, it is usually necessary to conduct no-load, load, high and low temperature, vibration, shock and other experiments on the steering gear. [0003] At present, the steering gear test equipment usually adopts the industrial computer mode, the equipment structure is relatively complicated, the volume is large, and the cost is high, so it is not convenient to carry and transport. In addition, some test equipment can only output and collect analog signals, such as spectrum analyzers, function signal generators, etc., and cannot d...
