The invention provides an axle balance control system, method and device, a platform car and a storage medium. The control system comprises an angle sensor, a limiting switch, a balance executing unitand a control device. The control device judges the complete machine state of an aloft work platform according to the amplitude change angle detected by the angle sensor and electric signals sent bythe limiting switch, sends corresponding control instructions to the balance executing unit based on the complete machine state, judges whether an axle balance function is abnormal or not according tothe complete machine state and feedback information, and carries out corresponding processing based on the judgment result. According to the system, method and device, the platform car and the storage medium, the reliability and stability of control can be improved; and the work reliability of the car is improved, safety accidents are avoided, and the overall control structure meets the requirements of standards.
Description
technical field [0001] The invention relates to the technical field of aerial work, in particular to a vehicle axle balance control system, method, device, aerial work platform vehicle, and a storage medium. Background technique [0002] The self-propelled aerial work platform can use its own power to walk short distances between work sites or sites, and is used to transport workers and use equipment to a designated height for operations. The axle balance system is used to ensure the stability of the aerial work platform during walking, that is, to ensure the stability above the turntable. When the aerial work platform is in the storage mode, when walking, the axle balance valve is opened, and the axle is adaptively adjusted on the uneven road surface (the drop is less than 150mm), so as to ensure stable boarding and comfortable operation for the operator. When the aerial work platform is in the operation mode, that is, the boom is lifted or extended, the center of the whol...
