Embodiment Construction

[0039] refer to figure 1 , the method is realized through 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. , after several cycles, the filter feature data collection is completed. And the initialization data required by the filter is generated after computer calculation.

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

Abstract

The invention discloses an automatic initialization method based on a pulse stepping motor frequency modulation filter. According to the automatic initialization method, an automatic initialization system composed of a computer, a motor driver, the pulse stepping motor frequency modulation filter, a test instrument and a voltage-stabilized source is used for simulating manual operation, wherein automatic initialization tools are arranged inside the computer; a loop is composed of the computer, the motor driver, the pulse stepping motor frequency modulation filter and the test instrument, feature data acquisition is completed through a plurality of cycles, and initial data needed by the filter are generated after computation of the computer. The automatic initialization method is high in accuracy and efficiency, convenient to implement and suitable for various frequency ranges, an unattended initialization process can be realized, and the generated initialization data can be verified. Process data and a result can be saved as files, so that the process is traceable. The automatic initialization method is characterized in that a tested product is controlled while the test instrument is controlled, control over the tested product and control over the test instrument are conducted in a cooperative mode, manual operation is completely simulated, the process data are recorded, and human errors can be avoided.

Description

technical field [0001] The invention relates to an initialization method for a frequency modulation filter using a pulse stepping motor in the communication field, and is particularly suitable for products using a frequency modulation filter using a pulse stepping motor with large output and high accuracy requirements. Background technique [0002] The filter needs to be initialized during the R&D and production process of pulse stepping motor FM filter, while 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 to reduce manual operations and avoid errors, and also to improve test efficiency. However, this device can be used in relatively low frequency bands and filter products with low precision requirements, and the test accuracy is not enough when used for higher frequency band filters, so that manual operation is sti...
