The monitoring device of the present invention can accurately measure human respiration and body temperature signals, is easy to wear, is more convenient to use, and can well meet the needs of family health monitoring. The specific composition of the wearable breathing and body temperature monitoring device is as follows:

1) The main part of the monitoring device is shown in Figure 1. It is mainly composed of a battery box, a main box and side plates on both sides, and the two are connected by positioning pins; the battery box is equipped with a lithium battery with a capacity of 1300mAh. Battery and body temperature sensor module; the main box is equipped with a breathing sensor assembly, two magnetic switches, a control circuit board and a magnetic switch cover; the overall length of the battery box and the main box is 80mm, and the width is 60mm to ensure restraint It will not cause discomfort to the human body when it is placed on the waist and abdomen, and meets the characteristics of easy wearing; the side panels on both sides are used to fix the chest belt woven from textiles, and the chest belt is connected by a buckle with an I-shaped buckle. The structure allows for easy adjustment of the length of the chest strap to accommodate different bust lengths. When wearing, it is bound on the chest and abdomen. After adjusting the length, it can be bound by quick connection through the buckle, and the frictional force caused by its own tightening prevents the sliding on the human body.

Half slot, the part between the two half slots is the connection part of the first slot and the second slot; the third slot on the right side of the bracket is connected with the chest strap. The breathing sensor assembly of this structure, because the connection between the first slot and the second slot is narrow, when the outer side of the first slot is pressed against the user's chest and abdomen, it can more sensitively transmit the force generated by the expansion and contraction of the chest and abdomen to the user's chest and abdomen. On the piezoelectric ceramic sheet of the piezoelectric ceramic sensor, it can not only ensure that the piezoelectric ceramic sheet can generate an obvious electrical signal due to being squeezed, but also protect the piezoelectric ceramic sheet from being damaged by external force.

3) The main box is mainly composed of a casing, a back cover, two magnetic control switches and a magnetic control switch cover plate for controlling the magnetic control switches. The main box adopts the laminated design as shown in Figure 3.

In the main program, the power-on initialization operation is firstly performed, that is, the port polarity configuration, timer configuration, serial communication setting, AD Sampling module and system interrupt configuration and other tasks, then clear the sampling times register and the data transmission flag to 0, then open the timer 0 interrupt (timer 0 time interval is taken as 20ms), then enter the loop program, wait for the data transmission flag bit to be set, Call the serial port data sending subroutine to complete the data package and send.

In the timer interrupt program, the timing sampling of breathing and temperature signals is completed, and the sampling frequency is set to 50Hz according to the timer configuration in the main program. After entering the interrupt program, start AD sampling, and judge whether to filter the sampling result according to the result of the sampling times. If the number of sampling times reaches 10, the filtering algorithm is used to de-noise the breathing signal and the body temperature signal, and the corresponding breathing rate and body temperature are calculated; then the data sending flag is set to 1, and the main program is notified to package the data and send it to the remote end. data processing equipment.
