The invention discloses a hydraulic oil online monitoring device. The online monitoring device comprises a pressure and speed reduction unit and a monitoring module (4), wherein an inlet of the pressure and speed reduction unit is connected with a hydraulic system to be monitored, and an outlet of the pressure and speed reduction unit is connected with an inlet of the monitoring module (4). Due to the fact that the pressure and speed reduction unit is arranged and the monitoring module is arranged on the downstream side of the pressure and speed reduction unit, high-pressure and high-flow-rate hydraulic oil to be monitored is converted into low-pressure and low-flow-rate hydraulic oil on the premise that the normal use of the hydraulic system is not affected. Due to the reduction of the pressure and flow rate of the hydraulic oil to be monitored, the online monitoring safety of the hydraulic oil can be improved.

The present invention provides a method for predicting employee operational risks based on logistic regression, comprising: S1, collecting operational risk point list data and employee information data; S2, classifying the risk points in the operational risk point list data; S3, extracting Operational risk events and employee information data of various risk points form an operational risk data set; S4, label employees according to the occurrence of operational risk events; Preprocessing; S6, based on the employee label, establish a logistic regression model for each type of risk point; S7, use the employee information data in the operation risk data set of each type of risk point after data preprocessing to train the corresponding logistic regression model; S8, use The trained logistic regression model calculates the probability of employees having various operational risk events. The invention collects employee information data, monitors employee behavior, does not need manual on-site inspection, and reduces labor costs.
