In this embodiment, before establishing a wireless network connection with the routers 22, 22 ', the IoT power socket 21, 21', 21 '' determines whether the IoT power socket 21 can directly connect with the router. The routers 22, 22 'establish a wireless network connection. If the IoT power socket 21 can directly establish a wireless network connection with the routers 22, 22 ', the IoT power socket 21 directly establishes a wireless network connection with the routers 22, 22'. If the IoT power socket 21 cannot directly establish a wireless network connection with the routers 22, 22 ', the IoT power socket 21 determines whether the next IoT power socket 21' can directly connect with the routers 22, 22 'Establish a wireless network connection until it is determined that there is an IoT power outlet that can directly establish a wireless network connection with the routers 22, 22' and an Internet of Things that can establish a wireless network connection with the routers 22, 22 ' The power outlet establishes a wireless network connection, and establishes a wireless network connection with the router 22, 22 'through an IoT power outlet capable of directly establishing a wireless network connection with the router 22, 22'.

For example, if the IoT power socket 21 cannot directly establish a wireless network connection with any router, the IoT power socket 21 determines whether one of the other networked power sockets can directly establish a wireless network connection with a router. Until it is determined that an IoT power socket can directly establish a wireless network connection with the router, for example, the IoT power socket 21 'can directly establish a wireless network connection with the router 22, and establish a wireless network connection with the router 22 directly. A wireless network connection is established with the Internet of Things power socket 21 ′, and a wireless network connection is established with the router 22 through an Internet of things power socket 21 ′ that can directly establish a wireless network connection with the router 22. The IoT power socket 21 determines whether one of the other IoT power sockets can directly establish a wireless network connection with a router, either after only one judgment or after multiple judgments.

If the IoT power socket is in an idle state, the controller controls the wireless communication unit to establish a wireless network connection with the IoT power socket. The environmental monitoring system according to item 2 or 3 of the scope of patent application, wherein:
The IoT sensor includes a memory, and the memory stores unique identification information of each IoT power socket;
The controller is configured to send an inquiry signal to an IoT power socket according to the unique identification information of the IoT power socket, and determine whether the IoT power socket responds to the inquiry signal within a preset time period to determine Whether an IoT power socket is idle;
If the IoT power socket does not respond to the inquiry signal within a preset time period, the controller determines that the IoT power socket is busy;
If the IoT power socket responds to the inquiry signal within a preset time period, the controller determines that the IoT power socket is in an idle state. The environmental monitoring system according to item 1 of the scope of patent application, wherein:
The number of the IoT power sockets is at least two, and before the IoT power sockets are connected to the router's wireless network, determine whether the IoT power sockets can directly establish a wireless network connection with the router;
If the IoT power socket cannot directly establish a wireless network connection with the router, the IoT power socket determines whether the next IoT power socket can directly establish a wireless network connection with the router until it is determined that there is an IoT The power outlet can establish a wireless network connection directly with the router, and establish a wireless network connection with an IoT power outlet that can establish a wireless network connection directly with the router, and can establish a wireless network directly with the router. The internet-connected power socket of the Internet establishes a wireless network connection with the router. The environmental monitoring system according to item 5 of the scope of patent application, wherein:
If the IoT power socket can directly establish a wireless network connection with the router, the IoT power socket directly establishes a wireless network connection with the router. The environmental monitoring system according to item 1 of the scope of patent application, wherein:
