一、自主生产酒店智能门锁 

1. 定制化能力：自主生产的品牌能够根据酒店的特定需求进行定制，例如特殊的外观设计、功能模块的选择等，更好地满足酒店的个性化要求。
2. 成本控制：自主生产可以更有效地控制成本，从原材料采购到生产流程优化，从而提供更具性价比的产品。
3. 技术创新：能够投入更多资源进行研发，不断推出新的技术和功能，如更先进的加密算法、生物识别技术的应用等，提升门锁的安全性和便捷性。
4. 质量把控：对整个生产过程进行严格的质量控制，确保每一把门锁都符合高品质标准，减少次品率和售后维修问题。
5. 快速响应市场需求：能够更迅速地根据市场变化和客户反馈调整产品线，推出适应新趋势的产品。
6. 供应链优势：自主生产可以更好地管理供应链，保证零部件的供应稳定，减少因供应链中断导致的交付延迟。
7. 本地服务支持：对于国内自主品牌，在服务响应和售后支持方面可能更具优势，能够及时解决酒店遇到的问题。
8. 数据安全保障：自主研发可以更好地掌控数据的安全性和隐私保护，确保酒店和客人的信息不被泄露。
9. 品牌形象塑造：通过打造优质的自主品牌，提升酒店的整体形象，展现其对科技和服务品质的追求。

二、Self-produced intelligent door locks for hotels

1. Customization capability: Self-produced brands can be customized according to the specific needs of hotels, such as special appearance design, selection of functional modules, etc., to better meet the individualized requirements of hotels.
2. Cost control: Self-production can control costs more effectively, from raw material procurement to production process optimization, thereby providing more cost-effective products.
3. Technological innovation: More resources can be invested in research and development to continuously introduce new technologies and functions, such as more advanced encryption algorithms, the application of biometric technology, etc., to enhance the security and convenience of door locks.
4. Quality control: Strict quality control is carried out throughout the production process to ensure that each door lock meets high-quality standards and reduces the defective rate and after-sales maintenance problems.
5. Quick response to market demands: It can adjust the product line more quickly according to market changes and customer feedback, and launch products that adapt to new trends.
6. Supply chain advantages: Self-production can better manage the supply chain, ensure the stable supply of components, and reduce delivery delays caused by supply chain disruptions.
7. Local service support: For domestic independent brands, they may have more advantages in service response and after-sales support, and can solve problems encountered by hotels in a timely manner.
8. Data security guarantee: Independent research and development can better control the security and privacy protection of data to ensure that the information of hotels and guests is not leaked.
9. Brand image building: By creating a high-quality independent brand, enhance the overall image of the hotel and show its pursuit of technology and service quality. 

三、创建新工程 create a new project

选择语言C++

所有类型:all project

四、填写dll名称 fill projec name

 五、工程创建完成

 六、新加函数方法 add function file

 七、新加头文件 add header file

 八、修改目标类型 modify project type 

 九、这只目标平台 set target platform

 十、编写代码 write code

#include <windows.h>
#include <iostream>
#include <fstream>
#include "CyberWinSmartLocker.h"using namespace std;extern "C" __declspec(dllexport) int Buzzer( int bz)
{std::string filePath = std::string("未来之窗智能物联") + ".txt";std::ofstream file(filePath);if (file.is_open()){//file << "读卡器声音";file.close();// return "字符串已成功写入文件";return 9;}else{//return "写入文件失败";return 4;}
}

十、头文件

#pragma once#ifndef CyberWinSmartLocker_d
#define CyberWinSmartLocker_d//宏定义导出
#ifdef CyberWinSmartLocker__//如果没有定义DLLH 就定义 DLLH __declspec(dllexport)
#define CyberWinSmartLocker __declspec(dllexport)//导出
#else
#define CyberWinSmartLocker __declspec(dllimport)//导入
#endif // DLLH__//如果没有定义DLLH 就定义 DLLH //编写代码区域//导出函数CyberWinSmartLocker int add(int a, int b);
CyberWinSmartLocker int sub(int a, int b);//导出类class CyberWinSmartLocker dllH
{
public:int mul(int a, int b);int div(int a, int b);
};//以C语言方式导出函数：
extern "C"
{CyberWinSmartLocker int Buzzer(int bz);}#endif

十一、注意事项 attention 

目标平台微32位数/X86 这样可以在xp，win7， 单片机上跑
