Blu-ray box alarm system based on single chip microcomputer

With the gradual development of medical and the advent of era of the "Internet of Things+"(IOT+), medical monitoring systems need a low-error, high-accuracy alarm device to detect and warn in timely. The Blu-ray box is a box-type medical device that uses light therapy to treat neonates with jaundice, and requires strict monitoring of neonatal body temperature and box temperature. Based on the background mentioned above, this paper designs and implements a suitable alarm system for Blu-ray box. The system uses 51 single-chip microcomputer as the control core and the DS18B20 thermo- sensor to collect and convert the temperature in real time, which will be compared with the given upper and lower limit value. When the temperature exceeds the threshold, a remote sound and light alarm is issued. The system structure, hardware circuit and software design are described in detail in this paper, and the system function is simulated and tested by both Proteus software and Keil software. Through this test, we can find out that the system has much better performance and wide practical prospect.
