Universal servo system test switching device

Abstract

The invention discloses a universal servo system test switching device, which comprises a sensor switching unit, a motor switching unit, a digital isolation input and output test unit, an analog input and output test unit, a centralized control unit, a communication interface and a control display terminal. According to the invention, processing of information of various types of sensors can be compatibly supported, current detection and power supply driving of various types of motors can be realized, and universal detection can be carried out on digital input and output ports, analog input and output ports and common external interface communication which may be provided by various types of servo drivers; and interaction, processing, storage, display and the like of various required test data are realized on the basis of DSP and FPGA architectures, so that the universality test for various servo drivers and servo motor products is realized. According to the invention, a universal design is adopted, so that servo drivers of various models or motors of various models can be tested independently, and the training and learning requirements of employees or students on servo systems of various types can be met.

Description

technical field [0001] The invention belongs to the field of servo system testing, in particular to a universal servo system testing switching device. Background technique [0002] Servo drives are electrical equipment used to control the high-precision operation of servo motors. As the domestic application of this type of products tends to mature, the product lineup is becoming more and more complete. However, most of the test devices in the production and processing links are only for a certain There is no universal test device for each model or a certain type of servo drive. For example, some focus on the automatic testing of specific peripheral IO, AD, fault and other interfaces of a single type of servo drive, and some focus on each fault point of the servo drive. The automatic detection and positioning of the automatic detection and positioning of the servo motor, and the visualization test of the current and speed of the servo motor. The specific use of the system lea...

[0002] Servo drives are electrical equipment used to control the high-precision operation of servo motors. As the domestic application of this type of products tends to mature, the product lineup is becoming more and more complete. However, most of the test devices in the production and processing links are only for a certain There is no universal test device for each model or a certain type of servo drive. For example, some focus on the automatic testing of specific peripheral IO, AD, fault and other interfaces of a single type of servo drive, and some focus on each fault point of the servo drive. The automatic detection and positioning of the servo motor, and some focus on the visual test of the current and speed of the servo motor. The specific use leads to excessive redundancy of test equipment. Therefore, the development of a general servo drive automatic test device is particularly important.
