A method and system for controlling a laundry processing device and equipment. The method comprises: after washing has finished, by detecting and determining whether, when configuring a washing program, a laundry processing device has been set with a subsequent operation at the end of washing, such as shaking loose and/or drying, and whether the current laundry processing device is in a work-at-home operation mode or a go-out operation mode, controlling the laundry processing device according to the determination result, so as to execute a corresponding shaking loose and/or drying operation item after washing is finished or unlocking the machine door to wait for a user to process, or the like. By means of a device control panel combined with a preset corresponding determination configuration of a subsequent operation after a washing program has ended at a remote end of an intelligent terminal, the human-computer interaction logic of control process configuration determination and processing is improved, and the dynamic switching of operation modes is combined, so that laundry processing after washing has finished is more simply, conveniently and intelligently implemented, better improving the human-computer interaction experience of a user, and having the features of low power consumption, low costs, and strong reliability, and device control being more flexible and well-developed.
