Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As described in the background, referring to fig. 1, a conventional bluetooth master node communicates with a slave node using a LIN/CAN bus. For example, a bluetooth master node 11 is provided in a cab of a vehicle, and bluetooth slave nodes 12, 13, and 14 are provided in a right side door, a left side door, and a trunk of the vehicle, respectively. It is necessary to provide a bus CAN1 between the bluetooth master node 11 and the bluetooth slave node 12, a bus CAN2 between the bluetooth master node 11 and the bluetooth slave node 13, and a bus CAN3 between the bluetooth master node 11 and the bluetooth slave node 14.
For other application scenarios, if the number of bluetooth slave nodes is larger, the number of buses to be arranged is larger, the wiring is more complicated, and correspondingly, the energy consumption of the communication is larger. Based on this, as shown in fig. 2, an embodiment of the present invention provides a data processing method based on a bluetooth SIG MESH, which is applied to a to-be-unlocked terminal shown in fig. 3, where the to-be-unlocked terminal includes a bluetooth master node 31 and at least one bluetooth slave node 32, where the bluetooth master node selects a friend node, the bluetooth slave node selects a low-power node, and the two nodes communicate with each other in the SIG MESH mode.
In this embodiment, taking an example that one bluetooth master node 31 is connected to three bluetooth slave nodes 32a, 32b, and 32c, a data processing method provided by the embodiment of the present invention is described, which includes the steps of:
and S21, acquiring the transmission quality parameters of each communication channel.
Wherein the transmission quality parameters at least include channel communication quality and signal strength. Generally, the normal range of channel communication quality is 0 to 255, with the larger the value, the better the link quality characterizing its communication channel. While the normal range of signal strength is-127 dBm to 20 dBm.
And S22, determining a target communication channel based on the transmission quality parameters.
And S23, controlling the Bluetooth master node to carry out data communication with the Bluetooth slave node through the target communication channel.
Specifically, the target communication channel is a channel through which the bluetooth master node and the bluetooth slave node perform data communication. Typically, there are 0-39 communication channels, as shown in FIG. 4. The inventor finds that currently, bluetooth transmits in three channels 37, 38 and 39, and once signal congestion occurs in the three channels, the problem of low signal transmission efficiency and the like is caused.
Therefore, in the embodiment, the quality of the communication channel is judged, the communication channel with good communication quality is determined to be the target communication channel, and the target communication channel is adopted for controlling the signal transmission between the bluetooth master node and the bluetooth slave node, so that the signal transmission efficiency is improved, and signal congestion is avoided.
Specifically, as shown in fig. 5, an embodiment of the present invention provides a specific implementation manner for determining a target communication channel based on the transmission quality parameter, including:
s51, determining a communication channel meeting preset conditions as a first communication channel based on the channel communication quality and the signal strength of each communication channel;
s52, determining the preset number of communication channels in the first communication channels as the target communication channels.
As mentioned above, there are generally 40 communication channels, and then the embodiment selects the first communication channel meeting the preset condition from the 40 communication channels, for example, it may be determined that the signal strength is greater than the first threshold according to the channel communication quality and the signal strength, and the communication channel whose quality rank is greater than the second threshold is the first communication channel.
For example, 18 communication channels are determined as the first communication channels from the 40 communication channels, and then 3 communication channels are randomly determined as the target communication channels from the 18 first communication channels.
Illustratively, in this embodiment, the quality of each communication channel may be ranked from high to low based on the channel communication quality, for example, taking the median as the second threshold, further combining the signal strength in the communication channel higher than the median, and when the signal strength is greater than the first threshold, for example, the first threshold is-85 dBm, determining that the communication channel meeting the two conditions is the first communication channel.
Therefore, the communication channel with good transmission quality is selected for signal transmission in the embodiment, and the transmission efficiency of the signal can be improved.
In addition, on the basis of the above embodiments, in the data processing method based on the bluetooth SIG MESH provided in this embodiment, as shown in fig. 6, the method further includes:
and S61, the Bluetooth slave node scans the broadcast packet sent by the external electronic equipment according to the target transmission rate.
In bluetooth 5, the conventional transmission rate is 1Mbps, but in this solution, because the SIG MESH transmission mode is adopted, the SIG MESH network can be set to operate in a low-rate mode, for example, the target transmission rate is set to 125kbps or 500kbps, so that the system has higher receiving sensitivity, thereby making the communication more stable and the communication distance longer.
On the basis of the foregoing embodiments, this embodiment further provides a manner how to implement SIG MESH communication between a bluetooth master node and a bluetooth slave node, as follows:
the method of factory default safe distribution network is adopted, namely, the networking between the slave node and the master node is completed before factory leaving, so that the slave node and the master node are in a communication distribution network state after factory leaving. Therefore, the process that after leaving the factory, each node needs to be configured one by one is avoided.
Specifically, the final purpose of the flow of the standard distribution network is to generate three keys, namely, a NetKey, an AppKey and a DevKey, in the sigmesh. Therefore, in this embodiment, the default distribution network is to fill the three keys into the storage unit in the production safety link. And ensures that each end to be unlocked (e.g., each vehicle) has a unique key pair. The key may be filled and read by using a secure encryption chip, or by using a partition access method, which is not specifically limited herein.
