通过研究Linux的线程机制和信号量实现读者写者(Reader
通过研究Linux的线程机制和信号量实现读者写者(Reader-Writer)问题并发控制。
1)写-写互斥:不能有两个写者同时进行写操作;
2)读-写互斥:不能同时有一个线程在读,而另一个线程在写;
3)读-读允许:可以有一个或多个读者在读;
4)读者优先的附加限制:如果读者申请进行读操作时已有另一个读者正在进行读操作,则该读者可直接开始读操作;
5)写者优先的附加限制:如果一个读者申请进行读操作时已有另一个写者在等待访问共享资源,则该读者必须等到没有写者处于等待状态后才能开始读操作。
-By studying the Linux thread mechanism and semaphores realize readers who write (Reader-Writer) the issue of concurrency control. 1) to write- write mutex: Can not write at the same time there are two write operations 2) read- write mutex: Can not have a thread at the same time in reading and writing another thread 3) Reading- Reading of permit: can have one or more readers read 4) the priority of additional restrictions readers: If the readers apply for a read operation, there was another reader being read, the reader can be directly started reading operation 5) to write additional priority Restrictions: If an application for a reader reading write operation has been in waiting for another visit to a shared resource, the read

运动控制卡回原点
针对MOTOMAN-HP20的示教编程、离线编程及远程控制方法进行了研究:以机器人夹持水杯倒水为例说明了机器人的示教编程方法;并以控制MOTOMAN-HP20机器人对12个堆放整齐的矩形零件进行搬运为例,通过远程控制软件MOTOCOM32实现机器人控制柜NX100与计算机之间的通信,从而操控机器人码垛;提出了现有机器人离线编程软件存在的不足之处。 最后,以LabVIEW为基础平台,设计、开发了一种新的离线编程软件,可以实现HP20多关节机器人的运动学正解与逆解运算,可完成空间任意两个约束点之间的直线插补和空间任意三个约束点间的圆弧插补。对于空间任意已知解析式的自由曲线能够较好地实现离线编程;对于二维平面内的任意未知曲线,该软件可以通过数据库中存储的各约束点的位姿,采用不同方法进行插值,并比较选出精度最高的差值方式,编辑、生成程序文件。软件的各部分功能均通过相应的实验进行了验证,能够操控机器人按照预期的轨迹进行运动。
