Specifically, in this embodiment, when the wireless router needs a sub-board design or expansion of sub-working boards, only one rate can be used for transmission between sub-boards. If the transmission rate needs to be changed, it needs to be manually set and switched. Because the smaller the value of the noise floor, the smaller the interference, the clearer the wireless signal, and the greater the required transmission rate. Therefore, by comparing the noise floor value of the Nth cycle with the preset noise floor value Therefore, the current required transmission rate of the wireless AP device can be determined according to the noise floor value, so that the wireless AP device can autonomously switch between the two rates of PCIE1.1 and PCIE2.0.

This embodiment can automatically adjust the transmission rate according to the specific situation. Ensure a balance between performance and interference.

Referring to FIG. 2, the present invention provides another embodiment of a method for adjusting a transmission rate, including:

S210 obtains the noise floor value and transmission rate of the Nth cycle, and compares the magnitude relationship between the noise floor value of the Nth cycle and a preset noise floor value;

S220 determine the magnitude relationship between the noise floor value of the Nth cycle and the preset noise floor value;

S230, when the noise floor value of the Nth cycle is equal to the preset noise floor value, control the transmission rate of the N+1th cycle to be the transmission rate of the Nth cycle;

S240, when the noise floor value of the Nth cycle is greater than the preset noise floor value, control the transmission rate of the N+1th cycle to be the transmission rate corresponding to PCIE 1.1;

S250 , when the noise floor value of the Nth cycle is smaller than the preset noise floor value, control the transmission rate of the N+1th cycle to be the transmission rate corresponding to PCIE 2.0.

Specifically, in this embodiment, by comparing the magnitude relationship between the noise floor value of the Nth cycle and the preset noise floor value, the actual transmission rate (PCIE1.1 or PCIE2.0) required for PCIE is obtained, so that the physical The transmission rate is better utilized, and while the utilization rate of the transmission rate is increased, the interference can be correspondingly reduced, so that the system bottleneck no longer exists on the PCIE, and at the same time, the maximum performance of the system transmission link can be ensured. The current required transmission rate of the wireless AP device can be determined according to the noise floor value, so that the wireless AP device can automatically switch between the two rates of PCIE1.1 and PCIE2.0. For example, the default transmission rate of router A is PCIE1.1. After router A is started, it will run data transmission at the transmission rate corresponding to PCIE1.1. If the noise floor is less than the preset noise floor value, then the router itself is interfered with If it is smaller, the transmission rate required for data or signal transmission is larger, so router A needs to switch its own transmission rate to PCIE2.0. If the noise floor is greater than the preset noise floor value, then the router itself is subject to greater interference, and the transmission rate required for data or signal transmission is smaller. Router A switches its own transmission rate to PCIE1.1. In this way, the transmission rate can be adjusted according to the real-time performance of the router itself, thereby saving bandwidth and improving bandwidth and resource utilization. By comparing the relationship between the noise floor value of the Nth cycle and the preset noise floor value, the actual transmission rate required for PCIE can be obtained. It is not necessary to increase the number of PCIE links to avoid increasing the complexity of hardware design. Maximize the use of switching PCIE rates to improve bandwidth usage.

S340, when the noise floor value of the Nth cycle is greater than the preset noise floor value, control the transmission rate of the N+1th cycle to be the transmission rate corresponding to PCIE 1.1 after a preset duration;

S350 , when the noise floor value of the Nth cycle is smaller than the preset noise floor value, control the transmission rate of the N+1th cycle to be the transmission rate corresponding to PCIE 2.0 after a preset duration.

Specifically, in this embodiment, by comparing the magnitude relationship between the noise floor value of the Nth cycle and the preset noise floor value, the actual transmission rate (PCIE1.1 or PCIE2.0) required for PCIE is obtained, so that the physical The transmission rate is better utilized, and while the utilization rate of the transmission rate is increased, the interference can be correspondingly reduced, so that the system bottleneck no longer exists on the PCIE, and at the same time, the maximum performance of the system transmission link can be ensured. Since the frequency of PCIE1.1 is 1.25GHz, the frequency of PCIE2.0 is 2.5GHz, the WIFI of the wireless AP device is 2.4GHz, and the general WIFI is 2.4GHz, the use of PCIE 2.0 will cause interference due to the similar frequency. Adjust the transmission rate of the N+1th cycle after the preset time period, that is, before each switch, it is necessary to maintain the preset period of time in the change area and then keep the trend of one minute, so as to avoid frequent switching, which can save system computing resources. CPU processing efficiency, thereby saving power consumption. It can also reduce disconnection.

If the current transmission rate of router B is PCIE2.0, if the measured noise floor at the current moment is less than the preset noise floor value, then the interference on the router itself is relatively small, and the transmission rate required for data or signal transmission is relatively small. If it is too large, router B needs to keep its own transmission rate at PCIE2.0, that is, the transmission rate does not change until the noise floor of router B is greater than the preset noise floor value at the next moment. When the interference increases, it will switch its own transmission rate to PCIE1.1 after a preset time period, such as one minute later. In this way, the transmission rate can be adjusted according to the real-time performance of the router itself, thereby saving bandwidth and improving bandwidth and resource utilization. By comparing the relationship between the noise floor value of the Nth cycle and the preset noise floor value, the actual transmission rate required for PCIE can be obtained. It is not necessary to increase the number of PCIE links and avoid increasing the complexity of hardware design. Maximize the use of switching PCIE rates to improve bandwidth usage.

Since the smaller the value of Noise Floor, the smaller the interference, the clearer the wireless signal, and the greater the required transmission rate. Therefore, by comparing the noise floor value of the Nth cycle with the value of the preset noise floor value range The size relationship can make the current required transmission rate of the wireless AP device be determined according to the noise floor value, so that the wireless AP device can autonomously switch between the two rates of PCIE1.1 and PCIE2.0.

For example, assuming that the preset noise floor value range is -80dBm to -95dBm, and the transmission rate of wireless router C is PCIE2.0 at this time, when the current noise floor of wireless router C is detected to be -104dBm, because -104dBm is less than - 80dBm, so until the next process to measure the local noise, the wireless router C keeps the current transmission rate PCIE2.0 unchanged. When the current noise floor of wireless router C is -78dBm, since -78dBm is greater than -95dBm, wireless router C switches its own transmission rate to PCIE1.1 until the next process to measure local noise before judging whether it needs to be switched Adjust the transmission rate of wireless router C. When the current noise floor of the wireless router C is -85dBm, since -85dBm is greater than -80dBm and less than -95dBm, the wireless router C saves the current transmission rate PCIE2.0 until the next process to measure the local noise. Change.

Referring to Figure 10, the present invention provides an example of a method for adjusting a transmission rate, including:

S101 sends GPIO signal by controlling CPU;

S102 controls the router to read the Noise Floor in the kernel;

S103 judges the relationship between the read Noise Floor and -85dBm;

S104 When Noise Floor＜-85dBm, switch the outgoing rate to PCIE2.0 after one minute;

S105 When Noise Floor=-85dBm, keep the last transmission rate unchanged for one minute;

S106 When Noise Floor＞-85dBm, switch the outgoing rate to PCIE1.1 after one minute;

In this embodiment, a fixed switching value is set. Here, the value of NOISE FLOOR is selected as the switching condition. NOISE FLOOR is a value comprehensively calculated by combining the transceiver performance and received power of the terminal. Experiments show that -85dBm is a performance from The point of good and bad, when it is less than -85dBm, switch to PCIE2.0, when it is greater than -85dBm, switch to PCIE1.1, keep the previous state unchanged at -85dBm, and need to keep it in the change area for one minute before each switch. The trend can be carried out in order to avoid frequent switching. Compared with the best existing technology, the present invention can realize automatic switching between the two transmission rates of PCIE1.1 and PCIE2.0, and has a better balance between performance and anti-interference.

Referring to FIG. 11, the present invention provides another example of a method for adjusting a transmission rate, including:

S111 sends GPIO signal by controlling CPU;

S112 controls the router to read the Noise Floor in the kernel;

S113 judges the relationship between the read Noise Floor and -80dBm～-85dBm;

S114 When Noise Floor＜-85dBm, switch the outgoing rate to PCIE2.0;

S115 when -80dBm＜Noise Floor＜-85dBm, keep the last transmission rate unchanged;

S116 when Noise Floor＞-80dBm, switch the outgoing rate to PCIE1.1;

In this embodiment, a judgment interval is set. The judgment interval is between -85dBm and -80dBm. When it is less than -85dBm, it is switched to PCIE2.0. When it is greater than -80dBm, PCIE1.1 is used. When it is between -80dBm, keep the state of the last PCIE rate unchanged. This embodiment supports two PCIE transmission rates at the same time, and the two transmission rates can be automatically switched to maintain a balance between performance and anti-interference, and the switching has no impact on the use of the customer, thereby improving the user's use experience.
