此次设计一款基于单片机的血压监测系统设计，该设计采用STC12C5A60S2作为此次设计的主控模块，通过血压监测模块对当前用户的收缩压和舒张压进行监测，监测的血压值通过LCD1602进行显示，同时通过蓝牙将监测的血压进行远程传输到手机端，用户可以通过按键设置血压的最大值和最小值，当监测到当前监测的血压值不在设置的正常范围之内进行语音播报处理，且监测完血压时，将监测得血压传输到液晶显示屏和手机端。此次设计的血压监测模块，用户可以在家进行使用，然后通过液晶显示屏进行数据的查看，此外可以将当前监测都的血压传输到家人的手机上或者传输到医生手机上。

Abstract：The design of a blood pressure monitoring system based on single chip microcomputer design, the design uses STC12C5A60S2 as the main control module of the design, through the blood pressure monitoring module to the current user’s systolic and diastolic blood pressure monitoring, monitoring the blood pressure value through LCD1602 display, at the same time through Bluetooth to monitor the blood pressure remote transmission to the mobile phone. The user can set the maximum and minimum blood pressure by pressing the button. When the monitored blood pressure value is not within the set normal range, the voice broadcast is processed. When the blood pressure is monitored, the monitored blood pressure will be transmitted to the LCD screen and mobile phone terminal. The designed blood pressure monitoring module can be used by users at home, and then the data can be viewed through the LCD screen. In addition, the blood pressure of the current monitoring city can be transmitted to the mobile phone of family members or to the mobile phone of doctors.
