Embodiment 1

[0058]Please refer to the attached figure 1 , is a structural schematic diagram of an electric steering gear testing device disclosed in the present invention.

[0059] The electric steering gear testing device is composed of an industrial computer 101 , a test transfer box 102 , an electric steering gear controller 103 and a simulated load platform 104 .

[0060] The specific link relationship is as follows:

[0061] The industrial control computer 101 is used to send digital control instructions to the test transfer box 102, and receive the digital feedback signal fed back by the test transfer box 102;

[0062] It should be noted that the commonly used external interfaces of industrial computers commonly used today are RS232 interface and USB interface. The industrial computer can only send and receive digital signals through these two external interfaces to communicate with the outside. Therefore, the electric steering gear test device , the industrial computer 101 can on...

Embodiment 2

[0072] Please refer to the attached figure 2 , is a structural schematic diagram of another electric steering gear testing device disclosed in the embodiment of the present invention.

[0073] The electric steering gear testing device is composed of an industrial computer 101 , a test transfer box 102 , an electric steering gear controller 103 , a simulated load platform 104 and an external power supply 105 .

[0074] The specific link relationship is:

[0075] The industrial control computer 101 is used to send digital control instructions to the test transfer box 102, and receive the digital feedback signal fed back by the test transfer box 102;

[0076] An automatic test module is installed on the industrial computer 101 for sending digital control commands to the test transfer box 102 and receiving digital feedback signals fed back by the test transfer box 102 .

[0077] The automatic test module includes electric steering gear test software, which sends digital control...

Embodiment 3

[0116] For the test device disclosed in the above embodiment, the present invention also discloses a test method for electric steering gear, please refer to the attached Figure 5 , the specific steps of the method are as follows:

[0117] S101: the industrial computer sends digital control instructions;

[0118] In the above testing device, the industrial computer is connected to the external communication equipment through the RS232 interface or the USB interface, and can only send digital signals. Therefore, during the test of the electric steering gear controlled by the industrial computer, only digital control instructions can be sent.

[0119] S102: The test transfer box performs communication protocol conversion on the digital control command, and when the electric steering gear to be tested is an analog type, digital-to-analog conversion is performed on the digital control command after the communication protocol conversion to generate an analog control command;

Abstract

The invention discloses a testing device and a testing method of an electric steering engine. The testing method is characterized in that a digital control instruction is sent and a digital feedback signal is received by an industrial control computer; communication protocol conversion is carried out upon the digital control instruction and the feedback signal by a test transfer box; when the electric steering engine to be tested is of analogue type, digital-to-analogue conversion is carried out upon the digital control instruction signal after communication protocol conversion to generate an analogue control instruction; analogue-to-digital conversion is carried out upon a feedback signal after communication protocol conversion to generate a digital feedback signal; the electric steering engine to be tested is controlled by an electric steering engine controller to drive a simulated load table to work according to the digital control instruction or the analogue control instruction, and a signal generated during work is sent to the test transfer box to be used as a feedback signal. According to the testing device and the testing method disclosed by the invention, the entire test device is commonly used in test of analogue and digital electric steering engines through functions of analogue-to-digital conversion and digital-to-analogue conversion of the test transfer box, so that the test process is simplified.

Description

technical field [0001] The invention relates to the technical field of electric servo control, and more specifically, relates to an electric steering gear testing device and method. Background technique [0002] The electric steering gear is the actuator of the guidance and control system of aircraft such as missiles and unmanned aerial vehicles. According to the signal output by the missile or UAV controller, the electric steering gear obtains the aerodynamic force and aerodynamic resistance moment generated by the deflection of the wing during the flight of the missile or UAV by manipulating the wings of the missile or UAV, thereby stabilizing And control the missile or UAV to make the missile or UAV fly according to the set track. [0003] Before carrying out the ground simulation test of the whole aircraft, it is necessary to test the function and performance of the electric steering gear assembled on the aircraft separately to ensure that the performance of the electri...
