Title:
METHOD FOR CONTROLLING LOADING OF AIRPORT CATERING TRUCK
Document Type and Number:
WIPO Patent Application WO/2021/012476
Kind Code:
A1
Abstract:
A method for controlling loading of an airport catering truck, comprising: when a power battery drives loading work, driven supporting legs to be supported only when the state of the whole truck satisfies the conditions of the normal working mode; the rising operation of a compartment is effective only when the state of the supporting legs satisfies the requirement for stably supporting the airport catering truck; a platform can be effectively operated to extend forwards only when the compartment reaches a rising end position; after the platform is operated by a worker to extend out, determine whether an obstacle affecting the extension of the platform exists or not, if yes, stop the platform extending out, and if not, drive the platform to extend out; when the worker operates the compartment to descend, first retract the platform; after the platform is retracted to the stop position, the worker is allowed to operate the compartment to descend; when the compartment effectively descends, the worker can effectively operate a refrigeration compartment to descend; after the compartment is descended to the descending stop position, the worker is allowed to effectively start supporting leg withdrawing. The safety operation of a loading system can be ensured by arranging a compartment ascending and descending condition, a supporting leg position condition, a platform stretching and retracting condition, and a truck start driving condition.
