Steering oil humidity monitoring method and system, engineering vehicle and readable storage medium

The invention relates to the technical field of engineering vehicle condition monitoring, and particularly provides a steering oil humidity monitoring method and system, an engineering vehicle and a readable storage medium. The steering oil humidity monitoring method comprises the steps that if a whole vehicle is powered on, the current water content of steering hydraulic oil is obtained; if the current water content exceeds the standard, oil change prompt information for changing the steering hydraulic oil is generated, and the oil change prompt information is sent to a vehicle condition prompter of the engineering vehicle; and if the interval duration between the moment when the current water content exceeds the standard and the moment when the steering hydraulic oil is replaced last time is smaller than the preset duration, maintenance prompt information for prompting maintenance of the sealing performance of the steering oil tank is generated, and the maintenance prompt information is sent to a vehicle co
