AI Technical Summary

Technical Problem

Existing proportional valve amplifiers lack effective status monitoring methods, making it impossible to grasp their working status in real time, and making it difficult to detect and handle abnormalities in a timely manner.

Method used

A proportional valve amplifier capable of remote monitoring was designed. The monitoring mechanism includes a temperature sensor, a current sensor, a communication module, and auxiliary components. The amplifier is monitored in real time via a wireless connection to a remote terminal. The temperature and current sensors collect data, which is transmitted to the remote terminal via the communication module. An alarm is triggered by an indicator light and a buzzer to indicate any abnormalities.

Benefits of technology

This enables real-time monitoring of the amplifier's status, timely detection and handling of anomalies, and improves the reliability and safety of equipment operation.

Abstract

This utility model relates to the field of amplifier technology, specifically to a proportional valve amplifier that can be remotely monitored, including a mounting plate and a monitoring mechanism. The monitoring mechanism includes an amplifier body, an extension plate, and a monitoring component. The amplifier body is detachably connected to the mounting plate, and the extension plate is fixedly connected to the amplifier body. The monitoring component includes a sealing frame, a temperature sensor, a current sensor, a communication module, and auxiliary components. The sealing frame is detachably connected to the extension plate. The temperature sensor is electrically connected to the amplifier body and located inside the sealing frame. The current sensor is electrically connected to the amplifier body and located outside the temperature sensor. The communication module is electrically connected to the current sensor and located outside the current sensor. The auxiliary components are fixedly connected to the sealing frame. This enables remote real-time monitoring of the amplifier's operating status, facilitating timely detection and handling of abnormalities by staff, and improving the reliability and safety of equipment operation.
