The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
The utility model provides an electrode cap for EEG signal collection of emotion recognition improves the contact effect of electrode and scalp thereby on the basis of current electrode cap in order to improve the effect that EEG signal collected.
As shown in fig. 1, the front view of the electrode cap of the present invention is shown, the electrode cap of the present invention has a cap body 1, a headband 2 and a connector 3, the connector 3 is disposed on the headband 2 for locking the headband 2, thereby fixing the cap body 1 on the head. The connecting buckle 3 belongs to the connecting buckle of the headband on the hat which is common in the prior art.
In fig. 1, a plurality of straps 4 are provided on the cap body 1. As can be seen from the top view of fig. 2, the strips 4 are ring-shaped, and the strips 4 are connected by a connecting member 5, thereby forming a cap frame. The strip 4 is provided with electrode assemblies 6, and the arrangement of the electrode assemblies 6 is shown in fig. 1 and 2. The electrode cap is provided with a left reference electrode 7 and a right reference electrode 8 on two sides thereof, which can be fixed at reference points (usually at/near the left and right ears in the prior art), and the left and right reference electrodes can be fixed in various ways, such as by elastic bands, adhesive tapes, etc.
As shown in fig. 3, in order to achieve the invention, the electrode assembly 6 has a fixing rod 9 and a supporting rod 10, the fixing rod 9 is fixed on the strip 4, one end of the supporting rod 10 is rotatably connected with the fixing rod 9 through a hinge seat 11, and the other end of the supporting rod 10 is fixed with a measuring electrode 15. Lower fixing rods 12 are arranged on two sides of the fixing rod 9, upper fixing rods 13 are arranged on two ends of the supporting rod 10, and springs 14 are connected between the lower fixing rods 12 and the upper fixing rods 13.
Because the utility model discloses an electrode assembly 6 can make measuring electrode 15 lean on to the scalp orientation, consequently strip 4 and connecting piece 5 can set to hard material.
The fixing rod 9 is provided with a lower limiting block 16, the supporting rod 10 is provided with an upper limiting block 17, and the lower limiting block 16 and the upper limiting block 17 are matched with each other to limit the opening position of the supporting rod 10 when the supporting rod 10 is rotated and opened, as shown in fig. 5. Since the spring 14 has a certain supporting function when it returns to its natural state, it is not necessary to provide upper and lower limiting blocks, and the support rod 10 can be supported by the spring itself when it is in the state shown in fig. 3 and 5.
The measuring electrode 15, the left reference electrode 7 and the right reference electrode 8 are all connected with collecting leads, not shown in the figure, but belong to the common connection mode with the electrodes in the field of electrode caps.
The utility model discloses well electrode assembly 6's working method as follows: as shown in fig. 3, 4 and 5, after the electrode cap is fixed on the head, the supporting rod 10 is pushed manually, after the supporting rod 10 passes through the position shown in fig. 4, the spring pulls the supporting rod 10 to be in the position shown in fig. 3, the measuring electrode 15 can be attached to the scalp under the action of the tensile force of the spring 14, and the spring 14 is still in a stretching state when the measuring electrode 15 is attached to the scalp so as to ensure that the measuring electrode is well attached to the scalp; after the measurement is finished, the support rod 10 is manually pulled apart to be in the state shown in fig. 5, and the spring 14 is still in the stretching state when in fig. 5 under the action of the upper and lower limiting blocks so as to keep the electrode assembly 6 in the position shown in fig. 5.
The collecting lead can be used for connecting with an external signal processing device, such as a signal amplifier, a filter, an A/D converter, a mode identification unit, a display and the like in sequence.
The display is used for the classification of show mood, and is concrete can divide into positive and negative mood with the mood, or can be with the further classification of mood, because the utility model discloses only provide an EEG signal's collection system, consequently only simply proposed the processing procedure after gathering, do not regard as the utility model discloses electrode cap's injecion.
