Abstract

Embodiments disclosed herein relate to systems and methods for monitoring and alerting a body temperature of a person under guardianship. A wireless signal emitting body temperature sensor is configured to transmit a wireless signal including a detected temperature value. The wireless signal is received by a wireless signal receiving chip of a wireless signal receiving and processing precaution device carried by a guardian, and processed by a central processing chip. If the detected value is over the maximum value or is under the minimum value, an alarming signal will timely notify the guardian about abnormality in the body temperature of the person under guardianship.

Claims

1. A method for monitoring body temperature and alarming a guardian comprising:

detecting a temperature value and transmitting the temperature value to a wireless signal receiving and processing precaution device comprising a wireless signal receiving chip, a fine-tuning terminal, and a central processing chip;

said detecting and transmitting comprising;

detecting body temperature to generate a temperature value by a temperature sensor;

transmitting the temperature value to a signal processing chip via flexible wires;

processing the temperature value by the signal processing chip;

emitting from a wireless signal emitting chip, a wireless signal of the processed temperature value;

receiving the wireless signal by the wireless signal receiving chip;

fine-tuning the received wireless signal by the signal fine-tuning terminal;

processing the fine-tuned wireless signal by the central processing chip to generate processed signals; and

sending the processed signals to a precaution device for alarming the guardian;

wherein receiving and processing the temperature value signal by the wireless signal receiving and processing precaution device comprising;

turning on a power supply of the wireless signal receiving and processing precaution device;

setting up and storing a threshold value and any preset increase or decrease in the threshold value within 3 minutes;

after 3 minutes, feeding in temperature values every 30 seconds from the temperature sensor;

storing the temperature values in the central processing chip;

after said feeding in the temperature values for 8 times, processing such fed temperature values by the central processing chip, comprising;

excluding the highest temperature value and the lowest temperature value;

calculating an average value of the remaining 6 temperature values to an accuracy of one decimal place;

adding a preset increasing value to the average value and setting the result as a maximum value, such that if a result by adding the preset increase value to the average value exceeds the threshold value, using the threshold value as the maximum value, and automatically using a value as a minimum value by subtracting two times of the preset decrease value from the threshold value;

otherwise subtracting the preset decrease value from the average value and setting the result here as the minimum value, and using the threshold value as the maximum value;

storing the maximum value and the minimum value; and

monitoring body temperature to alarm the guardian based on the detected temperature values against the stored maximum and minimum values.

2. The method for monitoring body temperature and alarming a guardian of claim 1, wherein a default threshold value for the central processing unit is 36.5°

C., and a preset increase value and the preset decrease value are both 1.5°
