Abstract

The invention relates to an IP (internet protocol) intercommunication control device with low cost and high real-time performance. The IP intercommunication control device comprises a PWM (pulse width modulation) unit, an SPI (serial peripheral interface) unit and an ADC (analog to digital converter) unit, wherein the PWM unit is used for outputting multi-path PWM signals and one path of hardware triggering signals, and comprises a PWM signal output controller, a control register and a hardware trigger signal generator, the SPI unit is used for receiving the hardware triggering signals, starting ADC sampling conversion and receiving sampling conversion results, and comprises a hardware trigger signal receiver, an SPI transmission controller and a receiving buffer, and the ADC unit is used for carrying out sampling conversion on simulation signals to be sampled output by a controlled device, and comprises a conversion controller and an output buffer. The invention provides the IP intercommunication control device with the advantages that the software intervention is not needed, the real-time performance is good, the precision is higher, the cost is low, and the real-time performance is high.

Description

technical field [0001] The invention belongs to the field of communication control, in particular to an IP interconnection communication control device. Background technique [0002] At present, pulse width modulation (PWM) technology has been widely used in industrial automation, energy saving and consumption reduction. In high-precision applications, the closed-loop feedback mechanism plays an important role. How to cooperate with PWM control and ADC analog-to-digital conversion The use of IP has become the focus and difficulty in the feedback mechanism of IP interconnection communication. Among the existing IP interconnection communication methods, the PWM technology and the analog-to-digital conversion ADC are used to coordinate and cooperate with each other. The software controls the output of the PWM signal to the controlled device. At the same time, after a specific time delay through the software, the software control starts Analog-to-digital conversion. Use softwa...
