[0002] Athletes and special environment workers who are in a high-pressure and high-load working environment for a long time face extremely high psychological pressure and physiological load, which will greatly affect the sports performance of athletes, reduce the decision-making ability and reaction speed of special environment workers, and seriously cause psychological problems such as anxiety and depression; electroencephalogram (EEG) signals can reflect the activation degree and fatigue state of the central nervous system, while biomarkers such as electrolytes, lactic acid, and cortisol in sweat can objectively evaluate the stress level and metabolic load; at present, although the collection technologies for these two types of physiological parameters have developed to a certain extent, there are still significant limitations in their applications in dynamic and high-intensity scenarios.

[0003] In the prior art, Chinese Patent CN111624790A designs an intelligent glasses and a glasses case, which mainly solves the wearable problem of pre-judging the abnormality of the wearing user in advance and timely treating the user when it is detected that the physiological characteristics indicate that the wearing user is in an abnormal state, but does not involve the joint collection and collaborative analysis of electroencephalogram signals and sweat signals; in particular, there is currently no portable head-mounted device that can monitor the brain activity state of athletes and special environment workers in real time through electrophysiological and electrochemical indexes without affecting their sports and working states, and can give early warning reminders when the state is abnormal; therefore, real-time monitoring of the brain activities of athletes and workers in special dangerous environments can help them identify these problems, evaluate their decision-making ability and reaction speed, ensure the safety and efficiency of operations, and provide timely psychological intervention and support.

[0087] In some embodiments, the transcranial electrical stimulation electrodes can also be configured as wet electrodes, sponge electrodes, and dry electrodes with other structures. For example, gel electrodes with Ag / AgCl, sponge electrodes with water storage properties, and bionic dry electrodes with good electrical conductivity characteristics are not limited in the embodiments of the present disclosure.

[0088] It can be understood that, by combining the physiological signal information of the wearer collected by the above-mentioned body fluid sensor and bioelectric sensor, real-time monitoring of the activity state of the wearer during exercise can be achieved, enabling athletes or special environment workers to better evaluate their physical state during activities. For example, monitoring the change range of brain physiological indicators during the exercise of athletes and recording the fatigue level and mental state of workers in special environments.

[0089] In this embodiment, the acquisition module is located in the installation bin on the outer side of the left temple and is connected to the electrode contacts for acquiring the physiological signals collected by the body fluid sensor and the bioelectric sensor.

[0090] It should be noted that the acquisition circuit of the above acquisition module includes a pre-filtering circuit, which performs signal preprocessing on the physiological signals collected by the sensor through hardware filtering, and the preprocessed physiological signals are then transmitted to the control module through a signal transmission interface.

[0091] In this embodiment, the control module is located in the installation bin on the outer side of the right temple and is connected to the electrode contacts for receiving the data signals transmitted by the acquisition module and sending the processed control instructions.

[0092] In this embodiment, the control module includes a communication chip and a battery module; the communication chip is used to send the test results transmitted by the control module to an external device and at the same time receive the control instructions returned by the external device; the battery module is used to supply power to the control module and the acquisition module.

When the test result exceeds the threshold signal, the control module input controls the transcranial electrical stimulation electrode to output the stimulation prescription, and the control module simultaneously uploads the warning information to the external device through the communication chip.

[0097] It should be noted that the threshold information includes the ion concentration parameters of Na+, Cl+, K+ and Ca+ in sweat under normal conditions, and the content parameters of glucose, lactic acid, cortisol and uric acid in sweat under normal conditions. The acquisition module will monitor the above indicators in real time and upload them to external devices through the communication chip of the control module.

At the same time, the data results processed in real time in the control module will also be compared with the preset threshold value. When the test result exceeds the threshold signal, the control module outputs a warning instruction. On the other hand, when the real-time data analysis results uploaded to the external device show that the current wearer's state is abnormal, the control module will also output a warning instruction after receiving the intervention instruction.

[0099] In this embodiment, the transcranial electrical stimulation electrode outputs a stimulation prescription including the following three gears:

[0100] Slightly stimulate the output to remind users of abnormal indicators;

[0101] Moderate stimulation output, reminding users to take a rest as soon as possible;
