Embodiment Construction

[0039] refer to figure 1 , the method is realized by a test platform composed of a computer 1, a motor driver 2, a filter 3, a network analyzer 4, a regulated power supply 5, and the like. It uses computer 1, motor driver 2, filter 3, and network analyzer 4 to form a loop. Computer 1 controls the network analyzer 4 and motor driver 2 according to the parameters set by the user, and collects the filter process data tested by the network analyzer 4. , and the filter characteristic data is collected after several cycles. And the initialization data required by the filter is generated after calculation by computer.

[0040] refer to figure 1 , the USB interface of the computer 1 is connected to the GPIB port of the network analyzer 4 through a USB-GPIB adapter card; the COM interface of the computer 1 is connected to the RS232 interface of the motor driver 2 through a cable; the motor driver 2 The power supply is provided by the regulated power supply 5 with two power supplies ...

Abstract

The invention discloses an automatic initialization method based on a frequency modulation filter of a pulse stepping motor. It simulates manual operation through the automatic initialization system composed of computer, motor driver, frequency modulation filter of pulse stepping motor, test equipment and regulated power supply. The automatic initialization tool is preset in the computer, computer, motor driver, frequency modulation filter of pulse stepping motor 1. The test instrument forms a loop, completes the characteristic data collection after several cycles, and generates the initial data required by the filter after calculation by the computer. The method has high precision, fast efficiency, convenient operation, and is applicable to various frequency ranges, and the initialization process can be unattended, and the generated initialization data can be verified. Process data and results can be saved as files to make the process traceable. The feature of this method is to control the tested product while controlling the testing instrument, and the two are coordinated to completely simulate manual operation, record process data, and avoid human error.

Description

technical field [0001] The invention relates to an initialization method using a pulse stepping motor frequency modulation filter in the communication field, and is particularly suitable for products using a pulse stepping motor frequency modulation filter with large output and high accuracy requirements. Background technique [0002] The filter needs to be initialized in the R&D and production process of the pulse stepper motor frequency modulation filter, and the traditional initialization requires manual operation of the instrument and control of the filter to collect filter characteristic data. Operation is error-prone. Subsequently, a test device was developed that could reduce manual operations to avoid errors and improve test efficiency. However, this kind of device can be used in relatively low frequency bands and filter products with low precision requirements. When used for filters in higher frequency bands, the test accuracy is not enough, so that manual operatio...
