Abstract
The invention discloses a Bluetooth technology-based multi-device automatic collision avoidance method and system. The method includes the following steps that: whether broadcast data to be transmitted are valid or not is detected, if the broadcast data to be transmitted are valid, a next step is executed, otherwise, the broadcast data is not processed; and the state of a transmission channel is detected, and the broadcast data are transmitted with a corresponding mode according to the state of a transmission channel. The system includes a data detection unit and a channel detection unit. According to the method and system of the invention, the activity situations of surrounding equipment are detected initiatively, and data transmitting and receiving behaviors of the equipment are adjusted according to the actual situation of the transmission channel; when data on the channel conflict, the equipment will wait to transmit data until a network is idle, and therefore, interference between the equipment can be effectively prevented, and collision occurring when data are transmitted simultaneously can be effectively prevented, and the stability of communication can be greatly improved. The Bluetooth technology-based multi-device automatic collision avoidance method and system of the invention can be widely applied to Bluetooth transmission technology.
Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of many equipment based on Bluetooth technology automatic avoiding method and system.
Background technology
Bluetooth is the radiotechnics of a kind of support equipment short haul connection (being generally within 10m).Wireless messages exchange can be carried out comprising between numerous equipment such as mobile phone, PDA, wireless headset, notebook computer, related peripherals.The standard of bluetooth is IEEE802.15, is operated in 2.4GHz frequency band, and bandwidth is 1Mb/s, and through development in recent years, we are no longer strange to it, and it is also module indispensable in current digital product.The appearance let us of Bluetooth technology when the various equipment of connection no longer fetter by various data wire, such as sound equipment, computer, mouse, keyboard, or even automobile.This technology be two equipment rooms carry out wireless short-range communication the most simply, method the most easily, also can communication between simplified apparatus and internet Internet, thus transfer of data becomes efficient more rapidly.
But, if when multiple equipment communicates, if now multiple equipment directly sends data simultaneously, be then easy to cause whole channel confliction, thus make the loss of data of transmission.
Summary of the invention
In order to solve the problems of the technologies described above, the object of this invention is to provide one and can avoid sending data collision, reducing a kind of automatic avoiding method of many equipment based on Bluetooth technology and the system of Communication Jamming.
The technical solution adopted in the present invention is:
Based on many equipment automatic avoiding method of Bluetooth technology, comprise the following steps:
Whether the broadcast data that A, detection will send is legal, if so, then performs step B; Otherwise, then this broadcast data is not processed;
The state of B, detection transmission channel, according to the state of transmission channel, carries out corresponded manner transmission by broadcast data.
As the further improvement of described a kind of automatic avoiding method of many equipment based on Bluetooth technology, described step B comprises:
If B1 transmission channel is in idle condition, then broadcast data is sent;
If B2 transmission channel is in busy state, then again detect the state of transmission channel after waiting for a delay cycle.
As the further improvement of described a kind of automatic avoiding method of many equipment based on Bluetooth technology, described delay cycle can according to the self-defined setting of actual conditions.
Another technical scheme of the present invention is:
Based on many equipment automatic avoiding system of Bluetooth technology, comprising:
Data detecting unit, whether legal for detecting the broadcast data that will send, if so, then perform channel detection unit; Otherwise, then this broadcast data is not processed;
Channel detection unit, for detecting the state of transmission channel, according to the state of transmission channel, carries out corresponded manner transmission by broadcast data.
As the further improvement of described a kind of automatic avoiding system of many equipment based on Bluetooth technology, described channel detection unit comprises:
Data transmission unit, if be in idle condition for transmission channel, then sends broadcast data;
Data latency unit, if be in busy state for transmission channel, then detects the state of transmission channel again after waiting for a delay cycle.
The invention has the beneficial effects as follows:
A kind of automatic avoiding method of many equipment based on Bluetooth technology of the present invention and system are by initiatively detecting surrounding devices active situation, according to the data transmit-receive behavior of the actual conditions adjustment oneself of transmission channel, when on channel, data clash, after equipment can wait for network idle, start again to send data, thus can effectively avoid interference mutual between equipment, effectively prevent from sending the situation that data produce collision simultaneously, greatly promote the stability of communication.
