Terminal charging base, terminal and environment monitoring system

The utility model provides a terminal charging base, a terminal and an environment monitoring system. A terminal charging base in the environment monitoring system comprises a first power supply module used for supplying power to the terminal charging base by using an external power supply input current, a monitoring module used for collecting environment parameters, and a communication module used for sending the environment parameters. The second power supply module is used for charging the terminal and supplying power to the terminal charging base through reverse charging of the terminal; the terminal comprises a power supply module and a battery, wherein the power supply module simultaneously has two functions of supplying power to the terminal by using current output by a terminal charging base and reversely charging the terminal charging base after external power supply input current of the terminal charging base is cut off; the battery is used for supplying power to the terminal after the external powe
