The invention discloses a three-in-one hat type intelligent monitoring early warning system and a control method thereof. The three-in-one hat type intelligent monitoring early warning system includes the following components of: a signal acquisition unit which is of a hat type structure so as to be worn in the head of a user, and includes a frame and three electrodes fixed at different positions of the frame, wherein the electrodes are used for acquiring electroencephalogram signals of the head of the user; a signal processing unit which receives the electroencephalogram signals transmitted by the signal acquisition unit and converts the electroencephalogram signals into feature vector signals, and stores and outputs the feature vector signals; an intelligent evaluation unit used for receiving the feature vector signals transmitted by the signal processing unit through a multi-parameter vector feature recognition module, and classifies and performs early warning judgment on the feature vector signals through a deep learning multi-parameter training module, and transmits early warning signals or stores the feature vector signals; and a positioning unit which receives the early warning signals transmitted by the intelligent evaluation unit and outputs positioning signals.

The invention relates to the field of physiological monitoring sensors and discloses a wearable flexible sensor for monitoring wrist pulse, a preparation method for the wearable flexible sensor for monitoring the wrist pulse, and a monitoring system based on the sensor. The wearable flexible sensor for monitoring the wrist pulse comprises a fabric object, a blocked layer formed on the fabric object and in contact with the wrist pulse region, a sensitive layer formed at the upper surface of the blocked layer, an electrode layer comprising at least two electrodes which lead from the sensitive layer or the surface of the sensitive layer, and a skid-friendly layer, wherein the sensitive layer is made of three-dimensional porous nanometer sensitive material, the skid-friendly layer and the blocked layer are made of high-molecular polymer and have bio-compatibility, and the skid-friendly layer and the blocked layer together package the sensitive layer. The wearable flexible sensor for monitoring the wrist pulse is thin and soft, capable of being processed into different shapes, and capable of being worn on the wrist pulse or attaching to the wrist pulse to monitor the pulse information.

The invention discloses a non-fixed-contact-type myoelectric acquisition system and a myoelectric acquisition method of the non-fixed-contact-type myoelectric acquisition system. The system comprises a plurality of myoelectric acquisition units, an electrode-array fixing device and a radio-frequency receiving module, wherein the myoelectric acquisition units are detachably installed on the electrode-array fixing device in the form of an array, and each myoelectric acquisition unit is wirelessly connected with the radio-frequency receiving module; the electrode-array fixing device is used for placing the myoelectric acquisition units, the myoelectric acquisition units and the skin are closely contacted by adjusting the electrode-array fixing device, and a connecting passage of a reference potential is provided for each myoelectric acquisition unit; the radio-frequency receiving module is wirelessly connected with the myoelectric acquisition units and is used for receiving myoelectric-signal characteristic information sent by each myoelectric acquisition unit and transmitting the myoelectric-signal characteristic information to an information processing terminal. According to the non-fixed-contact-type myoelectric acquisition system and the myoelectric acquisition method, a previous complicated cumbersome myoelectric acquisition device is changed and replaced with a wireless myoelectric-signal acquisition device which has the advantages of small size, light weight, low price, flexibility in placement, reusability and greater application value.

The invention discloses a portable anti-drowning dual-purpose lifesaving device and a working principle thereof. The device comprises a reactor and an oxygen gasbag, the reactor is connected with the oxygen gasbag through a first pipe, a one-way valve is arranged on the first pipe, and by means of the one-way valve, air inflation can only be conducted from the reactor to the oxygen gasbag; the reactor is connected with a one-way water inlet valve, sodium peroxide is placed in the reactor, the surface of the sodium peroxide is coated with a chemical protecting film, and a negative pressure cavity is formed inside the reactor; multiple acid acceptors are arranged inside the oxygen gasbag; a mouth-control oxygen supply valve is arranged on the oxygen gasbag; the one-way water inlet valve is connected to a start switch. The working principle is ingenious in design, and two lifesaving functions, namely the floating and oxygen supplying, are achieved on the lifesaving device. Compared with the prior art, the device has the advantages that according to the size and weight, the lifesaving device is convenient to carry even wear, and normal activities are not affected; the device can be used independently as lifesaving equipment, and the device and a belt or a watch can be made into a whole as well.
