温度系统程序可以根据不同的应用场景和需求以多种方式编写。以下是几种不同编程语言和环境下的温度系统程序示例:
1. Python 示例
```python
import time
import random
设定温度值
set_temperature = 25.0
def get_current_temperature():
"""模拟获取当前温度值。"""
这里随机生成一个温度值模拟真实传感器数据,实际应用中需从真实传感器读取。
return set_temperature + random.uniform(-1, 1)
def display_temperature():
"""显示当前温度和设定温度。"""
current_temp = get_current_temperature()
使用 ASCII 字符绘制温度计
thermometer_length = 30
level = int((current_temp - set_temperature) * thermometer_length / 5)
print(f"当前温度: {current_temp:.2f}°C")
print("温度计:")
for i in range(thermometer_length):
print(" " * (thermometer_length - i - 1), end="")
if i < level:
print("█", end="")
else:
print(" " * (i - level + 1), end="")
print()
主程序
while True:
display_temperature()
time.sleep(1) 每隔1秒更新一次温度显示
```
2. PLC 示例
```pascal
PROGRAM TemperatureControlSystem
VAR
DB1: DB;
Temperature1: REAL;
Temperature2: REAL;
HighAlarm: BOOL;
AlarmCounter: INT;
END_VAR
METHOD FC1: TemperatureCollection;
BEGIN
-- 读取AI模块通道1的模拟信号
Temperature1 := (AI_Module_Channel1.Signal * MeasurementRange) / 2^16;
-- 读取其他传感器数据
-- Temperature2 := ...
END_METHOD
METHOD FC2: AlarmLogic;
BEGIN
IF Temperature1 > 80 THEN
HighAlarm := TRUE;
ELSEIF Temperature1 < 20 THEN
AlarmCounter := AlarmCounter + 1;
IF AlarmCounter > 5 THEN
HighAlarm := TRUE;
END_IF;
ELSE
AlarmCounter := 0;
END_IF;
END_METHOD
METHOD OB1;
BEGIN
CALL FC1;
CALL FC2;
END_METHOD
```
3. 汇编语言示例
```assembly
ORG 0000H
LJMP START
START:
CLR P2.1
SETB P2.3
LOOP:
MOV A, P1
CJNE A, 14H, PP1
LJMP LOOP
PP1:
JC SW
CJNE A, 1EH, PP2
LJMP LOOP
PP2:
JNC JW
LJMP LOOP
SW:
SETB P2.1
LCALL DELAY
CLR P2.1
LJMP LOOP
JW:
CLR P2.3
LCALL DELAY
LJMP LOOP
DELAY:
MOV R0, 250
DELAY1:
DEC R0
JNZ DELAY1
RET
END
```
