Detailed Description
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a communication system 10 according to the present invention. In the present embodiment, the communication system 10 includes a mimo active antenna 100, a cpu 101, a temperature detecting unit 102, and a control unit 103. The temperature detecting unit 102 is electrically connected to the central processing unit 101. The control unit 103 is electrically connected to the cpu 101 and the mimo active antenna 100.
In this embodiment, each antenna in the mimo active antenna 100 can independently transmit and receive signals. The central processing unit 101 is set with an initial transmission rate, and under an initial default condition, the central processing unit 101 sets a highest transmission rate, and each antenna of the mimo active antenna 100 is in a working state. When communication system 10 is in operation, the temperature of communication system 10 may increase due to the emission of various heat sources (e.g., central processor 101, components of communication system 10, etc.). The temperature detecting unit 102 detects the temperature of the communication system 10 in real time. The control unit 103 determines whether the temperature detected by the temperature detecting unit 102 exceeds a first preset temperature, and reduces the transmission rate of the central processing unit 101 when the temperature exceeds the first preset temperature.
In this embodiment, the control unit 103 further determines whether the temperature is lower than a second preset temperature after reducing the transmission rate of the central processing unit 101 when the temperature exceeds a first preset temperature, and increases the transmission rate of the central processing unit 101 when the temperature is lower than the second preset temperature.
In this embodiment, when the temperature exceeds the first preset temperature, the control unit 103 reduces the number of working antennas of the mimo active antenna 100 to match the reduced transmission rate of the cpu 101.
When the temperature drops to be lower than the second preset temperature, the control unit 103 increases the number of working antennas of the mimo active antenna 100 to match the transmission rate raised by the cpu 101.
In an embodiment of the invention, the MIMO active antenna 100 is a MIMO8x8 antenna, all antennas of the MIMO8x8 antenna normally transmit and receive signals in the initial mode, and when the temperature exceeds the first preset temperature, the control unit 103 reduces the number of working antennas of the MIMO8x8 antenna, for example, to a MIMO6x6 antenna or a MIMO4x4 antenna. When the temperature drops below the second preset temperature, the control unit 103 increases the number of working antennas, for example, to MIMO6x6 antennas or MIMO8x8 antennas.

In this embodiment, each antenna in the mimo active antenna 100a can independently transmit and receive signals. The central processing unit 101a is set with an initial transmission rate, and under an initial default condition, the central processing unit 101a sets a highest transmission rate, and each antenna of the mimo active antenna 100a is in a working state. When communication system 10a is in operation, the temperature of communication system 10a increases due to the divergence of various heat sources (e.g., central processor 101a, components of communication system 10a, etc.). The temperature detecting unit 102a detects the temperature of the communication system 10a in real time. The control unit 103a determines whether the temperature detected by the temperature detecting unit 102a exceeds a first preset temperature, and reduces the transmission rate of the central processing unit 101a when the temperature exceeds the first preset temperature.
In this embodiment, the control unit 103a further determines whether the temperature is lower than a second preset temperature after reducing the transmission rate of the central processing unit 101a when the temperature exceeds a first preset temperature, and increases the transmission rate of the central processing unit 101a when the temperature is lower than the second preset temperature.
In this embodiment, when the temperature exceeds the first preset temperature, the control unit 103a reduces the number of working antennas of the mimo active antenna 100a to match the reduced transmission rate of the cpu 101 a.
When the temperature drops to be lower than the second preset temperature, the control unit 103a increases the number of working antennas of the mimo active antenna 100a to match the transmission rate of the cpu 101a after the rise.

The wireless communication module 105a transmits the real-time temperature of the communication system 10a to the external terminal device 20a, so that the user can know the temperature of the communication system 10a in real time through the external terminal device 20 a. The user can also send a speed-down command and a speed-up command to the wireless communication module 105a through the external terminal device 20 a. The wireless communication module 105a receives the speed reduction command and the speed increase command transmitted from the external terminal device 20 a. When the temperature exceeds a first preset temperature, the control unit 103a reduces the transmission rate of the central processing unit 101a according to the speed reduction instruction received by the wireless communication module 105a, and when the speed reduction instruction is not received within a preset time, the transmission rate of the central processing unit 101a is automatically reduced. When the temperature is lower than the second preset temperature, the control unit 103a increases the transmission rate of the central processing unit 101a according to the speed increasing instruction received by the wireless communication module 105a, and when the speed increasing instruction is not received for more than a preset time, the transmission rate of the central processing unit 101a is automatically increased.
