自助停车场的编程操作可以根据不同的技术平台和需求有所不同。以下是几种不同情境下的编程操作方法:
基于Python的简单示例
```python
class ParkingLot:
def __init__(self, capacity):
self.capacity = capacity
self.occupied = 0
def enter(self):
if self.occupied < self.capacity:
self.occupied += 1
print("车辆进入停车场")
else:
print("停车场已满")
def leave(self):
if self.occupied > 0:
self.occupied -= 1
print("车辆离开停车场")
else:
print("停车场已空")
实例化停车场对象
parking_lot = ParkingLot(50)
parking_lot.enter()
parking_lot.leave()
```
使用西门子S7-1200系列PLC的编程
```pascal
// 网络1: 停车场入口控制
NETWORK 1: 停车场入口控制
|---[车位空闲]---(启动门禁控制)---|
|---[车位已满]---(停车入库)-------|
// 网络2: 车辆检测与确认
NETWORK 2: 车辆检测与确认
|---[传感器检测]---(确认车辆进入)---|
|---[车牌识别]-----[车辆信息更新]
```
Linux下虚拟机服务器的C语言编程
```c
include include include include include int main() { int sockfd = socket(AF_INET, SOCK_STREAM, 0); if (-1 == sockfd) { perror("socket"); return 1; } struct sockaddr_in serv_addr; serv_addr.sin_family = AF_INET; serv_addr.sin_addr.s_addr = INADDR_ANY; serv_addr.sin_port = htons(8080); if (bind(sockfd, (struct sockaddr *)&serv_addr, sizeof(serv_addr)) == -1) { perror("bind"); return 1; } if (listen(sockfd, 5) == -1) { perror("listen"); return 1; } struct sockaddr_in cli_addr; socklen_t clilen = sizeof(cli_addr); int clientfd = accept(sockfd, (struct sockaddr *)&cli_addr, &clilen); if (-1 == clientfd) { perror("accept"); return 1; } char bufa = "欢迎来到长江智星智能停车场!\n"; write(clientfd, bufa, sizeof(bufa)); char buf = {0}; int i = 0; bzero(buf, sizeof(buf)); while (sockfd != -1) { sprintf(buf, "停车场共有%d个车位,当前停车场共有%d辆车,等候区共有%d辆车\n", MAX_STOP, s.top+1, (p.rear + 1)); write(clientfd, buf, sizeof(buf)); sleep(1); } close(clientfd); close(sockfd); return 0; } ```使用栈和队列模拟停车场的Python代码
