Miniature crane jib and landing leg partition limiting system and control method thereof

The invention relates to the technical field of cranes, in particular to a miniature crane jib and landing leg partition limiting system which comprises a detection module, a judgment module and a control module. Wherein the detection module comprises a plurality of sensor groups including a supporting leg attitude sensor, a supporting leg extension sensor, a lifting arm rotation angle sensor, a lifting arm extension sensor, a lifting arm elevation angle sensor and a lifting load sensor, the judgment module comprises a maximum lifting load meter and a non-maximum lifting load meter, and the control module comprises an operation panel and a display panel. When the crane is in a certain determined posture, the suspension arm is limited to rotate within a safe area range through the suspension arm rotation angle sensor, the hoisting weight is limited under the condition that the arm length and the operation radius are determined by calling the maximum hoisting weight meter or the non-maximum hoisting weight mete
