Self-checking method and system of water dispenser

The invention belongs to the technical field of a water dispenser, and discloses a self-checking method of a water dispenser and a self-checking system of the water dispenser. The method includes steps of step one, a signal simulation output module outputs a simulative signal to control the water dispenser to carry out self-checking running; step two, a signal analysis module receives and analyzesa feedback signal during the running process of the drinking water self-checking machine, and judging if the feedback signal is within a preset scale; step 3, if the feedback signal is under a presetscale, controlling the processing module to quit the self-checking program; step 4, if the feedback signal is out of the preset scale, correspondingly handling the processing module. Through sendingthe simulative signal to control the water dispenser to run related programs, and detecting every working parameter during the running process, the water dispenser can be judged if it is under the normal working state. When the
