Equipment control method and system related device

The invention discloses an equipment control system, which relates to the technical field of short-distance wireless communication, and comprises a first mobile terminal and a second mobile terminal,wherein the first mobile terminal establishes wireless fidelity (Wi-Fi) connection with the second mobile terminal after the wireless hotspot function is started, and transmits data to the second mobile terminal through a Wi-Fi antenna working mode of MIMO. The second mobile terminal is used for accessing the Internet through the first mobile terminal connected with the Wi-Fi. The first mobile terminal can monitor the residual electric quantity and/or the equipment temperature of the mobile terminal. The first mobile terminal is used for switching the working mode of the Wi-Fi antenna to SISOand/or switching the maximum forwarding rate of the TCP message or the UDP message to be less than the first rate and/or not responding to the detection request any more when the residual electric quantity is lower than a firs
