Disclosed is a multi-base station queued preambles allocation method based on collaboration between multiple agent, which provides a non-competitive preambles allocation method in a scenario of multiple base stations and multiple cells, so as to solve the congestion problem caused during random access of massive MTCDs. The devices are queued to select the preambles based on deep reinforcement learning, and a training method based on federal learning is applied, thus effectively solving the congestion problem caused by competitive access. First, the newly accessed devices are grouped and the level of priority is set according to a delay tolerance time. Then, the device are reasonably allocated to idle queues by means of a multi-agent reinforcement learning algorithm. Finally, by means of a federal training method, the neural network of each agent is synchronously optimized by means of average optimization of neural network gradients, thus completing preambles allocation to each agent.

The present disclosure provides an electric steam control method, a system thereof, and a steam cleaner. The method includes: obtaining current water temperature data of a hot water tank and a current power supply mode; determining whether a temperature corresponding to the current water temperature data is within a preset temperature range; and if the temperature is within the preset temperature range, entering a heat preservation mode, else detecting whether AC power is currently available; if the AC power is available, performing power supply using the AC power, else generating a water temperature alarm signal; and in the heat preservation mode, detecting whether a working state is currently in place; if the working state is in place, detecting whether the AC power is currently available and generating a steam ejection signal, and performing power supply by using the AC or DC power, else maintaining the heat preservation mode.
