道闸安装行业现状与技术分享
Current Status and Technical Sharing of Barrier Gate Installation Industry
6月22日已过，目前已安装两个道闸，但生意十分清淡。幸好我并非专职安装道闸，否则可能连饭都吃不饱。
June 22 has passed, and two barrier gates have been installed so far, but business is very slow. Fortunately, I'm not a full-time barrier gate installer, otherwise I might not even be able to make ends meet.
实际上，道闸很简单，只是有个很高端的名字——车辆识别管理系统。通俗来讲，也就是那么回事，没什么难度。
In fact, barrier gates are very simple, they just have a high-end name - Vehicle Recognition Management System. In simple terms, it's nothing special and not difficult.
道闸类型与工作原理
Types of Barrier Gates and Working Principles
一般来说，我安装最多的是直杆道闸、栅栏道闸、伸缩门和升降柱这四种。
Generally speaking, the four types I install most are straight-arm barriers, fence barriers, sliding gates, and rising bollards.
这个月安装的第一个是伸缩门，这东西没什么高科技，就是两个电机拖着一个门走来走去。你让它往左走它就往左走，让它往右走它就往右走。
The first installation this month was a sliding gate. There's no high technology involved - just two motors pulling a gate back and forth. You tell it to go left and it goes left, tell it to go right and it goes right.
智能控制系统解析
Analysis of Intelligent Control System
为了防止没人控制伸缩门的开和关，我们会在门口安装两个摄像机，一个对着门口，当有车子进入，且是摄像机允许进入的车子时，摄像机就告诉伸缩门可以开门了。
To prevent the sliding gate from operating without control, we install two cameras at the entrance. One faces the entrance, and when a vehicle approaches that the camera recognizes as authorized, it tells the gate to open.
这时没人知道车子是否真的开进了门内，还是刚好停在门槛上。这时摄像机就会问地感器，有没有感觉到车还在电感线圈上。
At this point, no one knows whether the vehicle has actually entered or is just stopped at the threshold. The camera then asks the ground sensor whether it still detects the vehicle on the induction loop.
硬件连接与管理系统
Hardware Connection and Management System
大家看到这个控制板，可能会觉得很复杂，但从使用的角度来说，其实很简单。虽然有很多接口，但只要你懂原理，就很容易接线。
The control panel might look complicated, but from a usage perspective, it's actually very simple. Although there are many interfaces, as long as you understand the principles, wiring is easy.
可以这样说，摄像头有离线功能，基本可以实现黑白名单控制开关道闸。但我们花几千甚至上万大洋买的这套系统，可不仅仅是为了让它实现简单的开门关门功能。
To put it simply, the cameras have offline functionality that can basically implement whitelist/blacklist control of the barrier gates. But the system we spent thousands or even tens of thousands on isn't just for simple opening and closing functions.
SEO优化建议
SEO Optimization Suggestions
对于外贸公司订单网，建议优化以下关键词：外贸订单系统、国际订单管理、跨境贸易平台等。
For foreign trade order websites, we recommend optimizing for keywords like: foreign trade order system, international order management, cross-border trade platform, etc.
关于吉林谷歌竞价推广，重点投放：吉林外贸推广、东北地区谷歌广告、吉林省企业海外营销等关键词。
For Jilin Google Ads promotion, focus on keywords like: Jilin foreign trade promotion, Google advertising in Northeast China, overseas marketing for Jilin enterprises, etc.
通过我的介绍，估计大家都明白了。这东西很简单，没有别人说的那么复杂。
Through my explanation, I believe everyone now understands. These things are actually very simple, not as complicated as some people make them out to be.
