中文翻译成英文 不要翻译器翻译的那种 请高手帮忙翻译一下谢谢

本设计的由单片机控制的自动加料系统是与料斗式干燥机配套的加料系统。根据加料工艺要求，其工作原理是：先将真空管关闭，启动电机，用低真空气流将塑料树脂粒子送入真空管，电机停转，再将粒子排入料斗，如此循环。
在设计的控制系统中，可用一个电机控制两个加料生产线，由方向阀切换。两个生产线既可单独运行，也可同时运行。假如两者同时运行，当一生产线输送结束后，判断到另一个生产线排料已经结束，那么，电机不停转而方向阀换向，从而为另一个生产线送料。这样可以发挥控制系统和电机的效率，从而实现供料自动化。
控制系统的控制器有单片机89C51和扩展电路组成，单片机控制继电器，继电器控制交流接触器，又由接触器控制电机等执行机构的运动。本控制系统可以根据送料工艺的需要，设置两条生产线的输送、排料、满料、空料等参数值，也可装载系统前次工艺参数值。

The design of single-chip microcomputer controlled by the automatic feeding system with hopper dryer feed supporting system. Charging process in accordance with the requirements of its working principle is: first vacuum tube to close, start motor, using low vacuum plastic resin particles will flow into the vacuum tube, the electrical switch to stop, and then particles into the hopper, and so the cycle.
In the design of the control system can control two motors feed a production line, from the direction switching valve. Can separate the two production lines running, can also be run at the same time. If both run, when a transmission line after the line judge to another has come to an end marker, then turn to the direction of the electrical non-stop for the valve, so as to feed another production line. That is a motor control system and the efficiency of feed in order to achieve automation.
Control system are single-chip microcomputer 89C51 controller and expansion of the circuit composed of single-chip microcomputer to control the relay, AC contactor control relay and contactor control by the implementing agencies, such as motor sports. The control system can feed the needs of technology, set up the delivery of two production lines, nesting, full feed, air feed, such as parameter values, the system can also be loaded with the value of the previous process parameters.
