Intelligent power management system and method for crawler crane

Abstract

The invention provides an intelligent power supply management system and a power supply management method of a crawler crane and relates to the technical field of crane power management. The intelligent power supply management system comprises an intelligent sensor IBS, a controller, a temperature sensor and at least one generator, wherein the controller acquires an environment temperature acquired by the temperature sensor, a state of charge SOC value of a storage battery monitored by the IBS, and a working condition signal of an engine of the crawler crane, a load state of an engine is determined according to the working condition signal, and an output voltage of a generator is controlled according to the environment temperature, the SOC value and the load state. The intelligent power supply management system is advantaged in that the output voltage of the generator is intelligently regulated and controlled by monitoring the environment temperature, the SOC value and the load state,the charging time of the storage battery is dynamically adjusted, power generation efficiency of the generator is improved, and oil consumption of the generator is reduced.

Description

technical field [0001] The invention relates to the technical field of power management of cranes, in particular to an intelligent power management system and power management method of crawler cranes. Background technique [0002] At present, the generators used for crawler cranes are ordinary generators. After the engine is started, the generators are driven to continue to generate electricity. Since the ordinary generators cannot achieve intelligent variable output of power generation, the battery can still be used when the battery is fully charged or even fully charged. Continuing to generate electricity will increase the fuel consumption of the engine, resulting in a waste of energy, and at the same time damage the service life of the battery. [0003] On the other hand, when the battery power is insufficient, the generator cannot quickly generate electricity according to actual needs, which may cause the on-board electrical appliances to fail to work normally. If the b...

[0002] At present, the generators used for crawler cranes are ordinary generators. After the engine is started, the generators are driven to continue to generate electricity. Since the ordinary generators cannot achieve intelligent variable output of power generation, the battery can still be used when the battery is fully charged or even fully charged. Continuing to generate electricity will increase the fuel consumption of the engine, resulting in a waste of energy, and at the same time damage the service life of the battery

[0003] On the other hand, when the battery power is insufficient, the generator cannot quickly generate electricity according to actual needs, which may cause the on-board electrical appliances to fail to work normally. If the battery power is seriously insufficient, it may even cause the crawler crane to fail to start normally and reduce work efficiency

[0004] For large crawler cranes, in order to ensure that the crane can work normally, it is necessary to arrange multiple engines and multiple generators. When multiple engines drive multiple generators to generate electricity for the battery at the same time, the situation of energy waste and battery overcharging is more serious.
