工业控制实现自动化与PLC的加入有非常大的关系,PLC在工业生产线中主要功能为:开环控制、模拟量闭环、数字量控制等,这在很多场景下可以取代传统的继电接触器控制系统,让工业控制系统实现自动化生产。此外,PLC除了控制外,还可以实现采集现场数据的功能,并且可以对数据进行统计和记录。

由于PLC大多数都使用了单片微型计算机,所以集成度非常高,这也增加了系统的可靠性。PLC的优势在于输入和输出功能模块兼具,可以针对现场不同的信号,采用与之匹配的模板与对应的设备相连接并采取控制。除此之外,PLC还具备变成容易、组态灵活、安装方便、运行速度快。

当前在PLC领域中,企业基本上都属于欧美日三个地区。欧洲以西门子、施耐德为主,美国市场以罗克韦尔、通用为主,而日本市场则以欧姆龙、三菱和松下。而国产品牌在PLC方面近些年也发展迅速,和利时、信捷电气、南大傲拓、汇川技术、英威腾等自主品牌也在致力研发PLC,不过仍是以中小型PLC为主,大型的PLC系统仍被国际品牌占据,国内自主品牌仍有很大的进步空间。


脉冲变压器变压的信号要比不同电源变压器的频率高的多,一般为10K-100kHZ,而普通电源变压器为50HZ。这样脉冲变压器的效率就要比普通变压器高得多,体积亦可以小很多,体积可以缩小--这就是开关电源比线性电源(普通电源变压器的电源)的特点之一。把正弦波变成脉冲波输出的不是脉冲变压器而是变压器前端的控制电路。他通过把PWM信号把被波整流成直流的市电调制成高频的脉宽电压,通过脉冲变压器变压,然后通过滤波整流把变压后的脉宽电压变成直流

The automation of industrial control has a great relationship with the addition of PLC. The main functions of PLC in industrial production line are: open-loop control, analog closed-loop control, digital control, etc. This can replace the traditional relay contactor control system in many scenarios and make the industrial control system realize automatic production. In addition, PLC can not only control, but also realize the function of collecting field data, and can count and record the data.

Because most PLCs use single-chip microcomputers, the integration is very high, which also increases the reliability of the system. The advantage of PLC is that it has both input and output function modules, and it can connect with the corresponding equipment and take control according to different signals in the field by matching templates. In addition, PLC also has the advantages of easy conversion, flexible configuration, convenient installation and fast operation.

At present, in the field of PLC, enterprises basically belong to Europe, America and Japan. Europe is dominated by Siemens and Schneider, while the American market is dominated by Rockwell and General Motors, while the Japanese market is dominated by Omron, Mitsubishi and Panasonic. Domestic brands have also developed rapidly in PLC in recent years, and independent brands such as Hollysys, Xinjie Electric, Nantah Alto, Huichuan Technology and Invigorate are also working hard to develop PLC, but they are still mainly small and medium-sized PLCs, and large-scale PLC systems are still occupied by international brands, so there is still much room for improvement for domestic independent brands.

The frequency of the signal of pulse transformer is much higher than that of different power transformers, which is generally 10K-100kHZ, while that of ordinary power transformers is 50HZ. In this way, the efficiency of pulse transformer is much higher than that of ordinary transformer, and its volume can be much smaller, which is one of the characteristics of switching power supply compared with linear power supply (power supply of ordinary power transformer). It is not the pulse transformer that turns sine wave into pulse wave, but the control circuit at the front end of the transformer. He modulates the commercial power that has been rectified into DC by the PWM signal into a high-frequency pulse width voltage, transforms it through a pulse transformer, and then transforms the transformed pulse width voltage into DC through filtering and rectification.
