Abstract
The utility model relates to an analog rotary transformer generator. A 32-bit DSPTMS320F2812PGFA chip is used as a control core, two 16-bit digital-to-analog conversion chips are used to build two analog signal generating circuits of the rotary transformer, and two RS422 serial ports, a watchdog reset circuit, an excitation power supply module, parameter setting keys and a liquid crystal display screen are also arranged. The analog rotary transformer generator is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of transformer generator, particularly simulates the generator of rotary transformer.
Background technology
Rotary transformer, as widely used angular position measurement element in modern servo system, is widely used in the fields such as photoelectric turntable, the control of weapon firepower and inertial navigation.And also bearing vital task as the demodulation module (revolve and become demodulation module) of output signal of rotary transformer.How the quality that becomes demodulation module is revolved in judgement, and the height of precision, is a difficult problem for the user who lacks special test equipment.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of simulation rotary transformer generator, and it is simple in structure, easy to operate.
The technical scheme in the invention for solving the technical problem is: taking 32 site DSPTMS320F2812PGFA chips as control core, build two-way rotary transformer simulating signal circuit for generating with two 16 analog-digital chips, also is furnished with two-way RS422 serial ports, watchdog reset circuit, excitation power supply module, parameter arranges button and LCDs.
The utility model is simple in structure, easy to operate.Precision is higher, and generator adopts the core of 16 figure place weighted-voltage D/A converters as rotary transformer simulating signal circuit for generating, and output angle precision reaches 1.2 jiaos points.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model schematic diagram.
Embodiment
As shown in Figure 1, the utility model is taking 32 site DSPTMS320F2812PGFA chips as control core, build two-way rotary transformer simulating signal circuit for generating with two 16 analog-digital chips, also is furnished with two-way RS422 serial ports, watchdog reset circuit, excitation power supply module, parameter arranges button and LCDs.
The concrete function of this generator is as follows:
(1) there are 16 (compatible 14) the digital output angle position signal abilities that receive;
(2) there are single or 2 demodulation of installation and resolve module testing and checking function;
(3) there is the controlled varying signal simulation circuit for generating that revolves of two-way: simulation angular velocity range-120～120 degree/second, angular range 0～360 degree;
(4) provide normal work required full-scale input;
(5) there is operation hours, status monitoring, fault alarm and defencive function;
(6) provide the test fixture (possessing embedded mounting condition) of tested module.
DSP, as the control core that revolves varying signal simulation circuit for generating, to produce the simulating signal of test request, and gathers the tested angle value DSP that revolves the generation of change demodulation module return simultaneously, judges the quality of tested demodulation module according to input, output angle value.
