On-line monitoring method, device and system for valve hall particles of converter station

The invention discloses an on-line monitoring method, device and system for valve hall particles of a converter station, and relates to the technical field of converter station valve hall monitoring.The on-line monitoring method comprises the steps of acquiring a particle parameter of air in a plurality of valve halls of the converter station in real time; judging whether the particle parameter confirms to a warning condition or not; sending warning information to outside according to a judgment result; uploading the particle parameter to a background by a wireless network so as to perform on-line monitoring, analysis, exhibition and storage of the data; and logging in and accessing the background to inquiry the data needed by monitoring. The particle monitoring device has functions of particle monitoring, temperature and humidity monitoring and Wifi remote transmission, and the system background has functions such as data trend analysis and warning. Bymeans of the system, the inspection operation of an opera
