    • A device for controlling an induction motor includes a voltage/frequency controller, a pulse width modulation controller, and a converter. The voltage/frequency controller receives a controlling frequency, and outputs a controlling voltage corresponding to the controlling frequency. The pulse width modulation controller receives the controlling voltage and the controlling frequency, and generates PWM signals according to the controlling voltage and the controlling frequency. The converter receives the PWM signals, and controls the induction motor according to the PWM signals. There is a predetermined relationship between the controlling voltage and the controlling frequency stored in the voltage/frequency controller. The controlling voltage is greater than zero in response to the controlling frequency being zero, and increasing the controlling frequency increases the controlling voltage as in the predetermined relationship.
    • 用于控制感应电动机的装置包括电压/频率控制器,脉宽调制控制器和转换器。 电压/频率控制器接收控制频率,并输出与控制频率对应的控制电压。 脉宽调制控制器接收控制电压和控制频率,根据控制电压和控制频率产生PWM信号。 转换器接收PWM信号,根据PWM信号控制感应电动机。 控制电压和存储在电压/频率控制器中的控制频率之间存在预定的关系。 响应于控制频率为零,控制电压大于零,并且增加控制频率按照预定关系增加控制电压。

    • A speed controller used in a control loop of a motor includes a comparator, a processing device, and an arithmetic logical unit (ALU). The comparator compares a received instruction speed or a received measured speed of the motor with a predetermined speed value, outputs a first signal to the processing device when the received speed is greater than the predetermined speed value, or outputs a second signal to the processing device when the received speed is equal to or less than the predetermined speed value. The processing device receives a speed difference between the instruction speed and the measured speed. The processing device outputs a first proportional value when the first signal is received, or outputs a second proportional value when the second signal is received. The ALU outputs an instruction current to the control loop by calculating the proportional value according to a predetermined calculation rule.
    • 在马达的控制回路中使用的速度控制器包括比较器,处理装置和算术逻辑单元(ALU)。 比较器将接收到的指令速度或接收到的电动机的测量速度与预定速度值进行比较,当接收到的速度大于预定速度值时,将第一信号输出到处理装置,或者向处理装置输出第二信号 当接收速度等于或小于预定速度值时。 处理装置接收指令速度和测量速度之间的速度差。 当接收到第一信号时,处理装置输出第一比例值,或者当接收到第二信号时输出第二比例值。 ALU根据预定的计算规则计算比例值,向控制回路输出指令电流。

    • A communication protocol detection system includes an active detection terminal and a passive detection terminal. The active detection terminal includes a first communication interface, a command sending module, and a response receiving module. The passive detection terminal includes a second communication interface, a command receiving module, and a response sending module. The command sending module is for sending a plurality of detection commands in sequence to the passive detection terminal via the first communication interface. The command receiving module is for receiving detection commands in sequence via the second communication interface, and sending detection commands to the response sending module. The response sending module is for determining whether a currently received detection command can be identified. If the currently received detection command can be identified, the response sending module sends a response to the active detection terminal to make the command sending module stop sending detection commands.
    • 通信协议检测系统包括主动检测终端和被动检测终端。 主动检测终端包括第一通信接口,命令发送模块和响应接收模块。 被动检测终端包括第二通信接口,命令接收模块和响应发送模块。 命令发送模块用于经由第一通信接口将多个检测命令依次发送到被动检测终端。 命令接收模块用于通过第二通信接口依次接收检测命令,并向响应发送模块发送检测命令。 响应发送模块用于确定是否可以识别当前接收到的检测命令。 如果当前接收到的检测命令可以识别,则响应发送模块向主动检测终端发送响应,使命令发送模块停止发送检测命令。
