The invention provides a hydrogen production system and a method for producing hydrogen by electrolyzing water. The hydrogen production system comprises an electrolytic bath, a gas-liquid separation device, a hydrogen side buffer tank and an oxygen side buffer tank, the number of the electrolytic cells is the same as that of the gas-liquid separation devices, each gas-liquid separation device comprises a hydrogen side separation device and an oxygen side separation device, and each electrolytic cell is correspondingly connected with one hydrogen side separation device and one oxygen side separation device; the hydrogen side buffer tank comprises a first hydrogen side buffer tank, the oxygen side buffer tank comprises a first oxygen side buffer tank, and the hydrogen side buffer tank and the oxygen side buffer tank are each provided with a first liquid inlet; a liquid outlet of each hydrogen side separation device is connected with a first liquid inlet of the first hydrogen side buffer tank, and a liquid outlet of each oxygen side separation device is connected with a first liquid inlet of the first oxygen side buffer tank; wherein the number of the separating devices is greater than that of the corresponding buffer tanks. Therefore, the gas flow path of each electrolytic cell can be independent, and the operation stability and the anti-interference capability of each electrolytic cell are improved.

The present application relates to the technical field of charging, and particularly relates to a data line and a massage control method thereof. The data line comprises a first input / output module, a main control module, a massage module and / or a second input / output module connected in sequence; the first input / output module and / or the second input / output module are connected with external equipment for inputting and outputting electric signals and data signals; the main control module receives and transmits the electric signals and the data signals, and simultaneously sends a control signal for controlling the start / stop and / or adjustment mode of the massage module; the massage module comprises a massage function part which performs a massage action according to the control signal. The data line of the present application can not only realize the basic functions of data transmission, equipment charging and the like of the data line, but also can enjoy massage at the same time. The user can independently control the start, stop and adjustment mode of the massage module, and the operation is simple and convenient, and the individuality and flexibility of the massage are improved.
