When matching is carried out, the central equipment and the peripheral equipment with the same identification parts are judged to be the same group, data interaction can be carried out only between the central equipment and the peripheral equipment of the same group, and after the central equipment receives a large amount of broadcast information, the target peripheral equipment can be quickly screened out according to the identification parts in the compared broadcast information, and the broadcast information which is not sent by the target peripheral equipment is abandoned, so that the workload of information extraction is reduced.
Specifically, when the central device receives the broadcast information sent by the peripheral device, the first two bytes of the MAC address are first matched: if the current two bytes are the same, judging that the peripheral equipment sending the broadcast information and the central equipment are the same group of equipment; when the current two bytes are different, it is determined that the peripheral device and the central device which send the broadcast information are not devices in the same group, and the central device directly discards the broadcast information when processing data. Therefore, when a large number of peripheral devices are arranged near the central device, data of different devices in the same group are discarded quickly, more time can be saved, and the data processing efficiency is improved.

The peripheral device is configured to save a peripheral device identification number as a MAC address, where the peripheral device identification number includes: an identification section for judging whether or not the devices are of the same group and an ID section for distinguishing different devices; the system is used for sending broadcast information to the central equipment and monitoring a scanning request sent by the central equipment; the central equipment is used for analyzing the scanning request, screening target central equipment and entering dormancy according to the scanning request of the target central equipment after receiving the scanning request from the central equipment.
It should be noted that the center device is further configured to match the received broadcast information according to the identification number of the center device: if the identification part of the peripheral equipment is the same as the identification part in the received broadcast information, judging that the peripheral equipment sending the broadcast information is target equipment, and extracting effective data in the broadcast information for storage; if the identification part is different from the identification part in the received broadcast information, the peripheral equipment which sends the broadcast information is judged not to be the target equipment, and the broadcast information is abandoned.
It should be noted that the peripheral device is further configured to match the central device that sends the scan request according to the peripheral device identification number: if the identification part of the scanning request is the same as the identification part in the received scanning request, the central equipment which sends the scanning request is judged to be target equipment, and the target equipment receives the broadcast information, the broadcast is closed, and the broadcasting is switched to sleep; if the identification part is different from the identification part in the received scanning request, the central equipment which sends the scanning request is judged to be not the target equipment, and the target equipment does not receive the broadcast information, and then the broadcast information is continuously sent, and the scanning request sent by the next central equipment is monitored and matched.
In a preferred embodiment, the peripheral device identification number and the central device number comprise an identification portion of two bytes and an ID portion of four bytes.
In a specific embodiment, the central device identification numbers of the central devices A1 and A2 are preset, and the peripheral device identification numbers of the peripheral devices B1, C1, and D1 are preset, so as to obtain the corresponding MAC addresses as follows:
the MAC address of the center device A1 is: 11 22 A1 A2 A3 A4;
the MAC address of the center device A2 is: 33 44 12 34 56;
the MAC address of the peripheral device B1 is: 11 22 B1 B2 B3 B4;
the MAC address of the peripheral device C1 is: 11 22 C1 C2 C3 C4;
the peripheral device D1, whose MAC address is: AA BB D1D 2D 3D 4.
After receiving the broadcast information of the peripheral devices B1, C1, and D1, the central device A1 first matches the first two bytes of the MAC address, and it can be seen that only the first two bytes of the MAC addresses of the devices B1 and C1 are the same as A1, so it is determined that A1, B1, and C1 are devices in the same group; if the first two bytes of the MAC addresses of D1 and A1 are different, it is determined that the two bytes are not the same group of devices, and the central device A1 directly discards the broadcast information of D1 and processes only the broadcast information of B1 and C1 when processing data. Therefore, when a large number of peripheral devices are arranged near the central device A1, the data of different groups are discarded quickly, more time can be saved, and the data processing efficiency is improved. Similarly, after the central device A2 receives the broadcast information of the peripheral devices B1, C1, and D1, the first two bytes of the MAC address are matched first, and since the first two bytes of the MAC address of the peripheral devices A2 and the first two bytes of the MAC address of the peripheral devices are different, it is determined that the peripheral devices are not the same group of devices, and the central device A2 directly discards the broadcast information of the peripheral devices B1, C1, and D1 when processing data.
When the peripheral device B1 receives the scan request from the center devices A1 and A2, the first two bytes of the MAC address of A2 are different from those of B1, so A2 and B1 are different groups, and B1 continues broadcasting. When the peripheral device B1 receives the scan request of A1, the first two bytes of the MAC addresses of A1 and B1 are the same, and it is determined that both are devices of the same group, so at this time, B1 considers that its data has been successfully received by the central device A1, and at this time, turns off the broadcast, and enters a low power consumption mode. At this time, the wireless radio frequency signals in the air are reduced, the communication interference is reduced, channel congestion can be correspondingly relieved, and the communication efficiency is improved. The other peripheral devices work the same way.
It should be understood that the above is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures or equivalent flow transformations made by the present specification and drawings, or applied directly or indirectly to other related technical fields, are included in the scope of the present invention.
