CC-PFB401

为了减少电机的故障率，需要定期对电机轴承进行检修保养，测试电机轴承温度，及时发现问题，定期加注黄油。一、当工控触摸屏硬件通道损坏时导致工控触摸屏乱跳失灵
 
    现象：点击工业触摸屏的某块区域，无反应，但是该区域周围被感应到，产生了触摸事件
    问题分析：工业触摸屏的感应区域是由一条条的感应通道组成的，若某几条感应通道坏了，那么点击该区域时，TP无法感应到电场。发生了变化，因此点击该区域时无反应，但是周围相邻的正常通道会感应到电场的变化，因此那块区域就会出现触摸事件。给人的感觉就是，触摸了这块区域，但是另外一块区域响应了。
    根本原因：工业触摸屏硬件通道损坏
    改进措施：更换硬件                 
 
 

  二、当工控触摸屏工作电压异常时导致工控触摸屏乱跳失灵
    现象：工业触摸屏无规律的乱跳
    问题分析：工业触摸屏无规律的乱跳，说明工业触摸屏自身工作不正常，当工业触摸屏的供电小于其正常工作电压时，会引起此现象。
    根本原因：工业触摸屏供电异常
    改进措施：修改工业触摸屏供电电压，使其正常，可能需要修改LDO供电，硬件有可能需要改板
 
    三、当工控触摸屏固件版本太低时导致工控触摸屏乱跳失灵
    现象：工业触摸屏可以正常使用，但是按下区域和响应区域成镜像反，例如按左边区域右边响应，按右边区域左边响应
    问题分析：工业触摸屏局部区域可以使用只是按下去不准确，但是但是中断正常，报点位置镜像反，引起此现象可能是工业触摸屏固件太老，当前驱动不匹配引起的 。
    根本原因：工业触摸屏固件不匹配
    改进措施：升级工业触摸屏固件
那么给电机加油的周期是多久？加注量是多少？选择什么样的油脂？加注量一般为1/2~2/3，加少了润滑效果不好，加多了会造成电机轴承过热；一般二极电机半年加注一次，四极以上电机一年加注一次，也可以根据有些电机厂对轴承要求的时间加注，他们一般都按运行小时计算。
电动机轴承加油方法：
1）平时、小修补充润滑油，可以根据情况把轴承内的摆放润滑油抠掉一些，然后补充少许润滑油。
2）大修全部更换，首先把电动机转子抽出定子，然后用汽油好好清洗，并等完全干后再加油。且加油数量为轴承室空隙的1/3~1/2即可，不能加油太多，否则轴承容易发热损坏。
首先要正确选择润滑脂，然后按以下要求加润滑脂：
①注意周围环境，必须保持润滑脂的纯净，切不可让灰尘、砂粒吹入及金属颗粒等杂质混入。
②加油的手指或竹片等工具必须干净。
③在轴承盖上加油时，不宜加得太满，以占轴承盖油腔的60%～70%为宜。
④在轴承上加油时，只要把润滑脂加到能平平地封住钢珠即可从PLC的组成来看,除CPU，存储器及通信接口外,与工业现场直接有关的还有哪些接口?并说明其主要功能。（1）输入接口:接受被控设备的信号,并通过光电耦合器件和输入电路驱动内部电路接通或断开。（2）输出接口:程序的执行结果通过输出接口的光电耦合器件和输出组件(继电器、晶闸管、晶体管)输出,控制外部负载的接通或断开。2、PLC的基本单元由哪几个部份组成?各起什么作用?（1）CPU:PLC的核心部件,指挥PLC进行各种工作。如接受用户程序和数据、诊断、执行执行程序等;（2）存储器:存储系统和用户的程序和数据;（3）I/O接口:PLC与工业生产现场被控对象之间的连接部件,用来接受被控设备的信号和输出程序的执行结果;（4）通信接口:通过通信接口与监视器、打印机等其他设备进行信息交换;（5）日前，ABB与全球的交通运输解决方案提供商斯堪尼亚(Scania)达成协一、低电压大电流

这里的“大电流”，指的是某设备在工作时，电路中的电流。而我们触电的时候，实际流过我们人体的电流，我们给它起个名字，就叫“触电电流”吧。

任何时候都是这样——工作电流一定要比触电电流大。为什么？电器在工作时，就比如说灯泡吧，这个灯泡在工作的时候，产生的电流是I工作=U/R灯。而当我们触电时，产生的电流就是I触电=U/(R灯+R人)。

人体的电阻阻值是很高的，因此，当电路中的电压很低时，由于R灯很小，所以工作电流（I工作）很大；当我们触电时，由于人体接入了电路，与灯泡串联了，而人体的电阻又比较大，电路中的电压又没变，所以触电电流（I触电）就很小了。二、高电压小电流

高电压和小电流也是一样——为什么电器的电压很高而电流很小？因为电器内部有很大的电阻呀！I=U/R，虽然电压U很大，但只要R也足够大，产生的工作电流就会很小。

电蚊拍就是这样的——电压3000V，电流只有0.1A。所以为什么人摸电蚊拍的电网时不会触电呢？人接触到电网，触电电流I=U/（R拍+R人）。此时流经人体的电流只会比0.1A更小，自然不会对人体造成伤害。三、安全电压和安全电流
As a global expert in digital transformation in energy management and automation, Schneider Electric has always focused on the growth and healthy development of small and medium enterprises, and launched the first quarter of the "Green Intelligent Manufacturing Win Program" in 2020.





On March 29, 2022, Schneider Electric launched the third quarter of the "Green Intelligent Manufacturing Win Program" as the ecosystem grows stronger. Based on the practice of the first and second quarters, Schneider Electric brought us more and better new highlights in the third quarter. Of industry and information technology, deputy director of the center for international economic and technological cooperation to Japan wenkai on launch special said: "despite the complicated and changeable environment and epidemic situation at home and abroad, the main body of small and medium-sized enterprises as the most active support economic development and the main force of innovation activities, made important contribution for the economic and social development, but also faced with many challenges. The state attaches great importance to the development of small and medium-sized enterprises. This year's Report on the Work of the Government has introduced a number of enterprise-friendly policies in terms of increasing incentives for enterprises to innovate, sticking to both bail-outs and training excellent enterprises, and focusing on fostering "specialized and innovative" small and medium-sized enterprises. The Ministry of Industry and Information Technology (MIIT), as the national authority in charge of promoting the development of small and medium-sized enterprises (smes), is also continuously strengthening the rescue and assistance of smes, strengthening the cultivation of high-quality enterprises, guiding smes to take the path of 'specialized, specialized and innovative' development, and promoting the transformation of digital and green industries."







And win plan, will help with intelligent manufacturing technology innovation potential small and medium-sized enterprises, breakthrough technology and business barriers, let the growing small and medium-sized enterprises to find new breakthrough, the rapid growth of high quality green intelligent manufacturing engineering and systems integration solutions provider, to have a real technical expertise in the field of small and medium-sized enterprises and industrial structures, "bridge" between application scenarios, Join hands to break through the "last mile" of digital transformation of industrial enterprises.







Taking this opportunity, INDUSTRIAL control network is very happy to have an in-depth exchange with Schneider Electric Industrial automation business China digital ecosystem, she shared with us her deep understanding of "green intelligent manufacturing win plan", the first two seasons of win plan replay feeling and expectations for the third quarter of win plan. Up to now, "Green Intelligent Manufacturing Wins Program" has provided technology and resources for more than 20 start-up enterprises, and a large number of innovative industrial technologies and application scenarios have emerged. At this year's launch ceremony, Hu Qihao, marketing director of Youhuilin Information Technology (Shanghai) Co., LTD., who participated in the 2021 Win Plan, said: "We have gained a lot in the training and POC practice, and we have opened up a new marketing idea and business track beyond expectations."







A man is not a hero, but a hero who gathers the hearts of all. According to the registration, landing, scenes and cooperation data of the previous two seasons, Schneider Electric has developed the entire ecosystem step by step, and the program has attracted more and more attention.







: "after the first two seasons at the depth of the win plan checking, we will continue in the future the informatization and industrialization depth fusion, practice more solid, looking for more valuable for industrial users, and integration into innovative small and medium-sized enterprises or science and technology enterprises, everybody together to build a series of lianchuang solution."
