Abstract
The utility model discloses a digital pulse generating device based on a full-digital DC controller. The digital pulse generating device comprises a full-digital DC controller and a sampling circuit. The output end of the sampling circuit is connected with the input end of the full-digital DC controller. The output end of the full-digital DC controller outputs digital pulses. Based on the conventional full-digital DC controller, the digital pulse generating device samples the analog quantity of a controlled object and controls the analog quantity by using a conventional software module valve function set in the full-digital DC controller so as to output digital pulses used by an external repeater or PLC. The PLC may use pulse signals as pulse counting or may analyze pulse width and pulse frequency. The digital pulse generating device achieves convenience and low cost and prevents a requirement for additional purchasing electronic circuit finished products.
Description
Technical field
The utility model relates to a kind of digit pulse and produces circuit, relates in particular to a kind of digit pulse based on the total digital DC controller and produces circuit.
Background technology
At present, digit pulse is used very extensive at the electric specialty of industrial automation, the generation way of pulse is generally based on electronic circuit, need remove to buy the electronic circuit finished product or form hardware-in-the-loop with electronic component in the time of general the use, insert required circuit and realize producing the purpose of digit pulse, the defective of the digital pulse generator of electronic circuit is: owing to be that electronic component and electronic circuit constitute, so operational failure and useful life are short; Adjust digit pulse frequency and pulse duration inconvenience.
The utility model content
The purpose of this utility model provides a kind of digit pulse generation device based on the total digital DC controller, and is easy to use, reliable.
The utility model adopts following technical proposals: a kind of digit pulse generation device based on the total digital DC controller, comprise the total digital DC controller, also include sample circuit, the output of described sample circuit is connected with the input of total digital DC controller, the output output digit pulse of total digital DC controller.
The utility model is based on existing total digital DC controller, by very simple sample circuit the analog quantity sampling is carried out in the initially signal source, and the existing valve collection of functions that utilizes total digital DC controller inside does fast, based on the signal of analog sampling, the processing of pulse duration and frequency in addition; Different analog signalses can produce the new digit pulse different with frequency of corresponding pulsewidth, these export new digit pulse as required, use for outside other auxiliary relay and PLC controller, this pulse signal can be regarded step-by-step counting, also can analyze the pulsewidth arteries and veins frequently, convenient, accurate, practical, do not need to purchase in addition again the electronic circuit finished product.
Description of drawings
Fig. 1 is enforcement circuit diagram of the present utility model.
Embodiment
A kind of digit pulse generation device based on the total digital DC controller of the utility model, comprise the total digital DC controller, also include sample circuit, the output of described sample circuit is connected with the input of total digital DC controller, the output output digit pulse of total digital DC controller, digit pulse refers to pulse duration and the adjustable digital signal of pulse frequency; The total digital DC controller is a kind ofly need use high-quality dc controller in industry spot, when for example needing to control direct current machine, and a large amount of equipment that use.
As shown in Figure 1, be control object with the alternating current machine of industry spot, in the alternation ripple of responding in the on-line operation process, and on the engineering in the required analog signal to be processed, for example: the rectified wave wave head; The rotor winding alternating electromagnetic induction ripple of synchronous machine etc.; Often press for and returned reason to produce desirable pulse square wave, these have the pulse square wave that certain physical features represents meaning, both can be used for the count pulse timing; Can be used for analyzing wave amplitude again, ripple is wide, and comparative analysis is used as a kind of control signal of new generation and is used.Described sample circuit is made of resistance R 9, R10, R11 and diode D3, A1(+), A1(-) voltage of an on-the-spot synchronous machine M is used in expression, R10/(R9+R10+R11 in this sample circuit) ratio, should make sampling value alternation amplitude 180V 〉=V1 〉=10V, herein+and 10V is the analog signals input voltage definite value of total digital DC controller MENTOR II regulation, 180V is the analog quantity input maximum of total digital DC controller MENTOR II terminal 9,10.The output valve of sample circuit is input in the total digital DC controller MENTOR II, valve collection of functions in the total digital DC controller MENTOR II is controlled, the valve collection of functions is the existing software module in the total digital DC controller, output non-0 after the valve collection of functions is controlled is 1, and desirable digital pulse signal is exported to PLC by the terminal 16 of MENTOR II in valve collection of functions control back.The utility model has been used on the core technology of synchronous machine total digital DC excitation unit, and the generation of said digit pulse is in the metasynchronism start-up course as synchronous machine, throws that the signal of encouraging uses, and is the part of excitation unit.
