Embodiment 1
[0032] Such as figure 1 As shown, a link control method includes the following steps:
[0033] Step 1, obtaining the first link quality;
[0034] Step 2, determining a new modulation method to be used according to the first link quality;
[0035] Step 3, obtain the current transmission power;
[0036] Step 4, if the current transmission power can make the microwave transmission equipment work normally under the new modulation mode, then determine the new modulation mode as the current modulation mode; otherwise, keep the original modulation mode as the current modulation mode.
[0037] Wherein, step 2 includes: if the quality of the first link is higher than the entry threshold value of the high-order modulation mode, then select the high-order modulation mode as a new modulation mode; if the quality of the first link is lower than the original modulation mode mode corresponding to the exit threshold, select the low-order modulation mode as the new modulation mode.

Embodiment 2
[0078] Correspondingly, the present invention provides a link control device, such as Figure 5 shown, including:
[0079] a first acquiring unit, configured to acquire a first link quality;
[0080] a modulation mode selection unit, configured to determine a new modulation mode to be used according to the first link quality;
[0081] a second acquiring unit, configured to acquire the current transmit power;
[0082] A modulation mode determining unit, configured to determine that if the current transmission power can make the microwave transmission equipment work normally under the new modulation mode, then determine that the new modulation mode is the current modulation mode; otherwise, keep the original modulation mode as Current modulation method.
[0083] Wherein, the modulation mode selection unit is specifically configured to: if the quality of the first link is higher than the entry threshold value of the high-order modulation mode, select the high-order modulation ...
