Abstract: The paper introduces a monitoring system using various sensors to collect information of the switch machine such as indication gap image (static), video (dynamic), action current, temperature, humidity, cylinder pressure and hydraulic oil level of electrohydraulic switch machines. Through saving, identifying, analyzing and recording the images and data received by monitoring software, the monitoring system will automatically give alarm information in case of ifnding abnormal conditions, it also can display the relevant oil level, oil pressure, the temperature, humidity, action current of the switch machine on the testing terminal.
