一、系统控制的控制过程分析(一)带盒进舱过程控制当磁带盒推入带舱,带盒夹持架向里移动,带舱右侧的带盒滑动开关的滑动臂左移,见图11。此时带盒状态电压由低电平转为高电平,微处理器 IC_(2001)脚(72)电压也由低电平变为高电平,发出带盒进舱指令。首先 IC_(2001)脚(53)为低电平 L,使螺线管吸合,变换杆开始动作,IC_(2001)脚⑩输出主导误差电压,脚(42)为低电平,主导电机正向运转,动力的传递顺序为:中心皮带
First, the system control of the control process (a) with the box into the process control When the tape cartridge into the ribbon compartment, the cartridge holder to move inward, with the right side of the cassette slide switch slider left, see Figure 11. At this time, the state of the tape box is changed from low level to high level, and the voltage of pin IC_ (2001) (72) of the microprocessor also changes from low level to high level to issue the instruction for entering the cartridge with the box. First of all, the pin (53) of IC_ (2001) is at low level L, the solenoid is engaged and the shift rod begins to operate. The dominant error voltage is output at pin IC_ (2001) and pin 42 is at low level. To the operation, the order of transmission of power: center belt
