编写一个代码基于STC15F2K60S2该数字温度计能够采集温度信息,并通过数码管进行实时显示。 能显示1分钟之内的最低温度和最高温度。设定27度为报警门限,超过此温度蜂鸣器发声报警

好的，下面是一个可能的代码实现，供参考：

注：

- 代码中使用了DS18B20温度传感器，需要连接到P3.7引脚。
- 代码中使用了数码管模块，需要根据具体型号和引脚连接进行调整。
- 代码中使用了蜂鸣器模块，需要根据具体型号和引脚连接进行调整。
- 代码中的温度记录数组长度为60，可以根据需要进行调整。
- 代码中使用了一个计时器来记录时间，可以根据需要进行调整。
- 代码中的报警门限为270，具体门限可以根据需要进行调整。
