Referring to fig. 2, fig. 2 is a schematic structural diagram of a second embodiment of the ad hoc network microwave communication device according to the present invention. Based on the first embodiment described above, a second embodiment of the ad hoc network microwave communication device of the present invention is proposed.

Therefore, when communication is performed, the distances between the ad hoc network microwave communication device and other nodes in the mesh network are changed accordingly. The allowed transmission power of the ad hoc network microwave communication device should meet the maximum transmission distance, however, when the transmission distance is small, such as 1/3 of the maximum transmission distance, there is energy waste in transmitting the microwave signal with the maximum transmission power.

In particular implementation, the second communication module 300 includes a power detection module, and the power detection module is connected to the control module 100. The power detection module is configured to perform power detection on the second microwave signal to obtain a power signal, and send the power signal to the control module 100; the control module 100 is further configured to generate an amplification instruction according to the power signal.
It should be noted that. The power detection module may use a power detection tube and other elements to perform power detection on the second microwave signal, and the control module 100 may determine the required transmission power according to the power of the second microwave signal. Specifically, the control module 100 may set the required transmitting power to be the same as the power of the second microwave signal, or set the required transmitting power to be the power after the power of the second microwave signal is preset and amplified.
Furthermore, in order to make the microwave signal cleaner, interference is avoided.

In particular implementations, the first filtering module and the second filtering module may include filters, such as bandpass filters. The modulated and amplified signal may have noise, and filtering may be performed to ensure that the signal-to-noise ratio of the signal meets a predetermined requirement. The specific operating frequency of the filter can be set according to the requirement, and the embodiment is not limited to this.
In the second embodiment, when the ad hoc network microwave communication device generates the transmission signal, the transmission power may be set according to the requirement, and the setting of the transmission power may be manually set, or adaptively adjusted by the control module 100, so that the power of the signal radiated by the antenna 2004 is reduced as much as possible on the premise that the transmission requirement is met.
