For wire rope tension of multi-rope friction hoist in coal mine, the imbalance problem always exists, so wire rope tension unbalance monitoring analyzer is designed and developed based on LabWindows/CVI.The instrument can collect skip rope tension and skip displacement data in the wellbore in real-time synchronously, the method of reading skip displacement data from the established OPC server in IPC directly is used, the cost of hardware is saved;The tension and displacement monitoring data of the skip can be stored in the MySQL database automatically, and can automatically plot each of wire rope tension-displacement history trend curve;When the wire rope tension unbalance degree value exceeds the limit and alarm information.The instrument device analyses the skip rope tension change law of the up and down movement in the wellbore reliably ,and further improves the system performance to enhance the security of the system in efficient and reliable operation performance.
