The invention provides a household gas tank human-friendly intelligent control system and relates to a control system and a control method thereof. The system comprises a power supply module, a sensor module, a single-chip microcomputer module, a storage module, a relay module, a ventilating device, an alarm and display module, a communication module and a control terminal. The method comprises the following steps: the sensor module collects data of a gas tank in real time and transmits the collected data to the single-chip microcomputer module; the single-chip microcomputer module processes the data and then, keeps the data to the storage module, and meanwhile, sends the data to the control terminal through the communication module and a network; and if judging the data is abnormal, the single-chip microcomputer module sends a short message to notify or remind a user, and meanwhile, carries out alarm and display, and when judging gas leaks, drives a driver module to start the ventilating device. The system can realize human-friendly intelligent control of the gas tank, has the advantages of being safe and reliable to use, fast in data transmission speed, long in distance, high in quality, low in cost and simple to operate and the like, and has wide market prospect.
