cross information meaning in English
非纵信息
Examples
- In the system , control unit accomplishes back - emf zero - crossing information reading and closed loop commutation . the system eliminates the pwm interferences and the commutating interferences by filtering with software algorithm . in order to make the bldc commutate exactly , the method of three - point estimation is used for phase locking in the system . the system also accomplishes several important objects , such as tmppt of photovoltaic arrays , unmanned supervision of the system , fault detection etc . the results of the experiment show that the device , which is made on the base of the principle above , can control the motor to complete the exact commutation
系统以motorola单片机jl3为核心，完成了系统外围硬件电路和控制软件设计，实现了直流无刷电机反电势过零检测，利用软件滤波的方式消除了pwm波干扰及换相干扰；采用三点预估算法，进行相位锁定，以完成直流无刷电机准确换相；同时实现了光伏阵列工作点的tmppt跟踪、系统无人监控和故障检测等功能。 - According to the data character in well and the processing power of cpu , a kind of reduction coding technique is proposed to meet the demands of practical well logging . especially , noting that the continuous zero - passing character of sound wave signal , the error - transmitting effect causing by coding is constrained efficiently by using the zero - crossing information
并根据实际测井的需求，针对井下数据的特点和cpu的处理能力，提出了一种压缩编码方法，特别是根据声波信号不断过零的特点，利用过零信息，有效地抑制了编码所带来的误差传播效应。
