Brain wave acquisition communication system, communication frame generating device and reading device

Abstract

The invention discloses an electroencephalogram collection communication system and an electroencephalogram collection communication frame generation device and reading device. The generation device collects EEG data from a plurality of channels and writes the EEG data into an EEG field in a data area in sequence, so a plurality of pieces of EEG data are located in the same frame and are sent together at the same time point, and the EEG data can be sent timely. The number of the EEG data is written into the EEG field; the number information can be carried in communication frames; even if the number of the EEG data is adjusted according to a practical demand, a reader of the communication frames can obtain the number information from the EEG field; the total EEG data is equally divided into a plurality of pieces of EEG data according to the number information, so the usage is relatively convenient and flexibly; the number of the EEG data can be adjusted, the lengths of the data formed by serially connecting the EEG data are inconsistent among different frames, and the lengths of the communication frames are not fixed; and compared with a fixed length communication mode, a non-fixed communication mode has the advantages that channel bandwidth resources are utilized well and a bandwidth utilization rate is improved.

Description

technical field [0001] The invention relates to the field of brainwave communication, in particular to a brainwave acquisition communication system, a communication frame generating device and a reading device. Background technique [0002] At present, brain wave products generally collect and analyze brain wave signals (EEG) and extract the degree of concentration. The controller simply judges the human brain control request through the change of concentration and combined with the movement direction of the human body, such as controlling the movement of the ball, Switch music, focus training, and more. However, in order to reduce judgment errors, EEG products generally need to collect EEG data from multiple regions of the human brain for comprehensive analysis. Since the human brain is very sensitive, the communication speed of EEG data is required to be fast enough so that it can be used in the newly collected areas. Before the arrival of the EEG data, the previous EEG d...

However, in order to reduce judgment errors, EEG products generally need to collect EEG data from multiple regions of the human brain for comprehensive analysis. Since the human brain is very sensitive, the communication speed of EEG data is required to be fast enough so that it can be used in the newly collected areas. Before the arrival of the EEG data, the previous EEG data are sent out, but the current communication method is a fixed-length frame structure communication, and only one EEG data can be sent at the same time point, which causes the sending time of multiple EEG data to be too long, and cannot Before the arrival of the newly collected EEG data, complete the sending tasks of the previous EEG data

In order to solve this problem, the existing brain wave products generally increase the collection interval of EEG data, but this will sacrifice the overall sensitivity of the brain wave products, and also increase the risk of misjudgment, so the symptoms are not the root cause
