RDDV valve digital controller based on Internet of Things

Abstract

The invention discloses an RDDV valve digital controller based on the Internet of Things. The controller comprises a control module, a power driving module, a parameter acquisition and conditioning module and a communication module; the control module mainly comprises a main control chip, a state indicating lamp, a control software algorithm and the like; the power driving module mainly comprises a driving signal isolation module and a driving bridge circuit; the parameter acquisition module mainly comprises a controller and some state parameter acquisition and conditioning circuits; the communication module mainly comprises a CAN communication module and a wireless communication module. The problem that an existing RDDV valve controller is low in digital intelligence degree is solved; a pure software algorithm control mode is adopted, so that the control flexibility and the anti-interference capability of the direct-drive servo valve are greatly improved, and the requirements of different users can be met; the controller multi-sensor acquisition and the Internet of Things technology solve the problems of cooperative control, state monitoring, equipment maintenance and upgrading difficulty and the like among the equipment.

Description

technical field [0001] The invention relates to the field of direct drive servo valve control and monitoring, in particular to an RDDV valve digital controller based on the Internet of Things. Background technique [0002] The rotary direct drive servo valve (RDDV) uses a direct drive motor to directly drive the movement of the spool. Due to its small size, fast response, high precision and strong anti-pollution ability, it is widely used in industrial controls such as aviation, aerospace, ships, and manufacturing. field. At present, the domestic application in the field of RDDV valve control is still mainly based on the construction of analog circuits, which lacks human-computer interaction and is not intelligent, which brings difficulties for on-site debugging, remote control and equipment upgrades; [0003] The application of the RDDV valve is usually in some relatively harsh environments such as high temperature, high noise, and vibration, which are harmful to human hea...

AI Technical Summary

Problems solved by technology

At present, the domestic application in the field of RDDV valve control is still mainly based on the construction of analog circuits, which lacks human-computer interaction and is not intelligent, which brings difficulties for on-site debugging, remote control and equipment upgrades;

[0003] The application of the RDDV valve is usually in some relatively harsh environments such as high temperature, high noise, and vibration, which are harmful to human health. At the same time, it is difficult to obtain and store the operating status information in real time during the use of the equipment. The process of monitoring, maintenance, and troubleshooting becomes complicated and inconvenient, and the work efficiency is low; for the application of multi-device collaborative control, it is mainly realized by bus interconnection at present, and the cable distribution is complicated and error-prone
