Electric valve actuator based on wireless network cloud platform

Abstract

The invention discloses an electric valve actuator based on a wireless network cloud platform, and belongs to the field of pipeline automatic control. The electric valve actuator comprises a bottom plate, wherein the bottom plate is connected with a main control panel, a relay control panel and a power panel; the main control panel is connected with a display panel and the relay control panel; the main control board comprises an MCU, an analog quantity feedback module and a battery charging module; and external signals are acquired through the bottom board, fed back to the MCU, and output to other functional modules from the MCU. A normal three-phase power open-phase alarm function is realized, and a three-phase power phase sequence detection function can be realized; each module board solves the problem that the product does not fall off and is abnormal in the vibration process through a floating connecting device; a function of controlling the operation of the product by using Bluetooth is added; due to the 4G module function, the function of using a wireless network of the product is added, and acquired data can be fed back to the cloud platform; and a battery mode seamless switching circuit achieves that the MCU is not affected under the condition that the mains supply is switched to the battery, and can be used for controlling an electric valve.

Description

technical field [0001] The invention relates to a valve actuator. Background technique [0002] Electric valves are usually used in pipelines and are controlled and managed by valve controllers. In the prior art, the valve controller is controlled by an 8051 single-chip microcomputer to achieve the control of driving the valve motor switch. The control logic is complex, the volume is too large, and it is easy to be interfered by the outside under special working conditions. The remote controller is used to realize one-to-one operation; the terminals are often easy to fall off, resulting in no response on the operation page; the three-phase fault alarm is falsely reported, causing the MCU to work abnormally, because the MCU directly samples the AC high voltage, which makes the MCU vulnerable to interference from the high voltage ground. Contents of the invention [0003] The purpose of the present invention is to provide an electric valve actuator based on a wireless netwo...
