工业机械异常检测

您怎么知道一台机器是否在正常运行？问题的回答是：通过利用深度学习来检测工业机器的常规振动数据中的异常情况。异常检测有很多用途，而尤其在预测性维护中特别有用。这个深度学习的例子讲的是基于双向长短期记忆网络（biLSTM）的自动编码器。虽然这个词很拗口，但它仅表示训练网络来重构“正常”数据。这样，当我们给算法提供一些看起来不同的数据时，重构错误会提示您机器可能需要维护。当您所拥有的数据均为“正...[详细]

新能源汽车是选择混动好还是纯电动好

我们在城市出行的时候，都会觉得电动汽车好处还是很多的，作为代步工具的它，也能够很好的完成自己的使命。现在大城市越来越多的小区有电动汽车专用车位，可以随时充电。当然这只是一种配套服务，真要使用起来可能一个星期才用充一次电，这也跟现在电动汽车的续航里程有直接的关系。很多人也禁不住为新能源汽车叫好，觉得很快就可以取代燃油汽车。不过我们却发现似乎还是我们国内非常热闹，在欧洲那些老牌汽车企业，在电动...[详细]
语音识别技术原理简介

语音识别技术原理简介自动语音识别技术(Auto Speech Recognize，简称ASR)所要解决的问题是让计算机能够“听懂”人类的语音，将语音中包含的文字信息“提取”出来。ASR技术在“能听会说”的智能计算机系统中扮演着重要角色，相当于给计算机系统安装上“耳朵”，使其具备“能听”的功能，进而实现信息时代利用“语音”这一最自然、最便捷的手段进行人机通信和交互。语音识别技术所面临的问题...[详细]

关于STM32单片机的IAP实现

一、基础概念什么是IAP？IAP即在应用中编程(In-Application Programming IAP)，简单的说就像是一个用户自定义的升级程序。实际上，STM32单片机的程序烧写有多种方法，可以用JTAG，也可用串口通过ISP软件烧写新程序。 JTAG的方式需要专用的烧写工具，在产品布置到现场后，更新产品程序比较麻烦，而通过串口的ISP软件升级方法可以直接使用常见的串口线升级程序，十...[详细]
高频纯正弦波通信逆变器Rs232和Rs485通迅接口的差异

深圳宝威特电源高频纯正弦波电力，通信逆变电源有两个通迅接口，Rs232和R485接口，它们的功能和特点都有所不同。一、接口： 1.Rs232采取不平衡传输方式，即所谓单端通讯。而RS485则采用平衡传输，即差分传输方式。 2.Rs232 只允许一对一通信，而RS-485 接口在总线上是允许连接多达128个收发器。 3.Rs232被定义为一种在低速率串行通讯中增加通讯距离的单端标准。 4.R...[详细]
插电式混合动力汽车在冬季使用时有哪些注意事项

很多时候我们都会听说，纯电动汽车在冬季的时候使用需要注意什么样的问题，甚至很多车主都会去做相关的攻略，如对于车辆采取“随用随充”原则，车辆使用完毕后立即进行充电，因为此时电池温度相对较高，可以提高充电效率。另外也会提前为出行做一些规划，避免续航里程不够的情况，甚至在出行的不敢开空调来进行取暖。由于纯电动汽车设计的原因，在冬天使用空调取暖的，是相当耗电的，另一个方面用开空调出热风慢也是一个方...[详细]
