试验台控制系统有Singleton,Observer,State设计模式。Singleton模式把类的构造方法隐藏在静态方法后面,保证系统中仅有1个类的实例被创建。Observer模式定义对象间一对多的依赖关系,1个对象状态发生变化时,所有依赖它的对象都得到通知并自动更新。State模式则将对象状态行为局部化处理,不同状态的行为保持独立。 Test bed control system has Singleton, Observer, State design patterns. Singleton mode hides the constructor of the class behind the static method, ensuring that only one instance of the class is created in the system. The Observer pattern defines one-to-many dependencies between objects. When an object’s state changes, all objects that depend on it are notified and automatically updated. State model will be the state of the object localization behavior, the behavior of different states remain independent.
