Therefore,this paper briefly analyzes and discusses the application and implementation of PLC technology in mechanical andelectrical control devices.Keywords: Mechanical and electrical; control device; PLC technology; systemIn the mechanical and electrical control devices, the previous working methods have not been maintained for along time, and sometimes they are prone to failure. Therefore, they cannot meet the standards for the development ofsociety today. To prevent the occurrence of such a situation in the traditional way, it is necessary to mainstream anadvanced technology in mechanical and electrical machinery. This is PLC technology. PLC technology is a newemerging technology. Compared with the previous working methods, it has many advantages, such as perfect controlsystem and advanced technology. And the response after applying PLC technology is also very good, at the same time itcan be used in many places, reliable and safe, and it can repair and control the previous frequent problems. Although thePLC system is relatively complicated, it is very simple in practice and the equipment is updated quickly. Therefore, it iswidely used in mechanical electrical control devices.1. A brief introduction to PLC technology1.1 The development background of PLC technologyThe rapid development of computer information technology has laid a foundation for PLC technology.

Electronics Science Technology and Applicationonly if the information technology of computers has been improved, PLC technology will also improve. The 1970s is animportant turning point in the development of control technology. Researchers have developed and developedcontrollers that can edit programs, and they have been installed in cars and put into industrial production. The resultsobtained are significant. The emergence of PLC technology in the 1990s, with the passage of time, its ability to controland calculate has been improving, based on this, the field of mechanical and electrical applications have applied PLCtechnology, until now, this technology is still improving and has been playing an important role in related fields.1.2 The general principle of applying PLC technologyNow popular PLC technology is an electronic device combining computer technology and automation technology.It can be used for editing and storage, and it can also calculate the data in various programs, and can establish theanalog and link between the output and the input program port, so as to achieve the full control of the production ofmechanical and electrical equipment on a line.1.3 The basic structure of PLC technologyPLC technology is mainly composed of five basic structures, the most basic is the power and memory, the secondis the input of the output interface, and then a built-in editor, and finally the expansion slot. The five parts, which arecombined with the effective control of the data and power, become a complete body, and the outside also needs toestablish a control scheme with practical operation meaning through the nature of a device. Only in this way can wefully demonstrate its effectiveness in the field of mechanical electricity[1].2. PLC technology applied to mechanical and electrical control2.1 Application of PLC technology in air compressorIn conventional mechanical and electrical control devices, most of the functions of a single device are realized by asingle-chip microcomputer. This method is easily interfered with by the outside world, resulting in a reduction in thework efficiency of the mechanical and electrical control device. In addition, previous air compressors have experiencedsafety accidents due to their immature technology and poor quality. PLC technology draws lessons from the previoustechnology, and combines the advantages of the previous technology, abandons the immature technology,simultaneously carries out the technological innovation, effectively combines automation and crisis control technology,and applies it to the air compressor in the mechanical and electrical control device, making the operation of aircompressor more safe, efficient and stable. In addition, the rational use of micro controller in the control device, PLCtechnology can fully control the mechanical operation, and safe and reliable, and then improve the working efficiencyof the electrical appliances[2].2.2 Reasonable application of PLC technology in mechanical and electrical safety monitoringIt is of great significance to carry out effective and scientific safety monitoring in mechanical and electricalequipment. Application of PLC technology can automatically manage the control and automatic monitoring ofmechanical electrical equipment, through the sensor system to monitor the operation of the electrical equipment, can berelated to the data within a certain period of time to the professional control and technical personnel. If a mechanicalfailure occurs, the safety monitoring system will immediately stop the working equipment, transmit the related fault tothe center of the control, and then analyze the fault in detail and integrate the scientific information to solve the fault. Tosolve the problem of equipment failure in a short time, not only can the equipment continue to operate safely, but also itcan reduce many unnecessary losses.2.3 Effectively apply PLC technology in mechanical electrical control systemIn the past, many power switches of unimproved electrical control systems were built on one to one, in this way, itis difficult to manage and use it with a lot of difficult operation, and even very easy to be disturbed by the outside. TheElectronics Science Technology and Application Volume 5 Issue 2 | 2018 | 3effective application of PLC technology can simplify the automation control procedures of mechanical electricalequipment, simplify the electrical control circuit and compress space. This will not only be able to operate effectively ina short time, but also make the electrical system more reliable and safer. During the actual operation of the mechanicaland electrical control device, the PLC technology, through the spontaneous fault analysis and diagnosis, and the controlperformance of the computer, carries out supervisory control to the running electrical equipment, and quickly finds outthe problems and analyzes the cause of the problem. At the same time, it is necessary to control the spread of theproblem and cure the source of the problem through scientific means to ensure the normal and efficient operation ofmachinery and equipment[3].3. Several ways to realize PLC technology in mechanical electrical controldevice3.1 Design a more complete control systemIf we want to realize the practical application of PLC technology in the mechanical and electrical control device,the most perfect is to design a more complete control system to strengthen the control ability of the program in thecontrol device. Based on the rational application of the PLC control system function, different schemes are designedaccording to the different functions of the system, the design of each part of the system is closely linked to theformation of a complete control system, and the PLC technology plays an effective role in the centralized controlsystem. This not only can take a very little time to design the control system, but also allows the device control systemto be rigorous and reliable. PLC technology will make the central control system work more efficiently, and the cost ofapplication is not high. If a problem occurs when the PLC technology is used in a centralized control system, the systemoperation should be stopped immediately to ensure the stability and safety of the product. If PLC technology is used in adecentralized control system, it should be based on the decentralized control of different objects, effectively combiningeach production line, and then collecting data for analysis. In the control of the production line, several machines arearranged and different PLC is applied to different objects to ensure that the other production lines can still worknormally when problems arise[4].3.2 Scientific analysis of schematicsThe schematic diagram can clearly reflect the core of a equipment work, which can ensure the high quality of theequipment and the high quality of the system. The schematic diagram can play a great role in testing, using a device, oreven when the equipment is optimized. Therefore, the effective application of PLC technology requires a scientific andrational analysis of the schematic design. The schematic diagram can clearly show the problems existing in thetechnology, and can also directly improve and optimize the system and immature technology. In the design of theschematic, each professional technician has different thinking and evaluation criteria, while the experimental operationof the equipment needs to be in a specific time and place, and then according to the current equipment related to theprinciple of the design of the schematic. Comprehensive scientific analysis of the schematic is an important step, whichis closely related to the actual operation of PLC equipment in the relevant equipment. To better use the PLC technologyin the mechanical electrical control device, it is necessary to analyze the various circuits in the design device whendesigning the schematic diagram and rationally optimize the schematic diagram so as to strengthen the PLC applicationin the control device.3.3 Effective control of analog quantitiesThe analog quantity in this paper is that when the mechanical and electrical control device is running, there will bea quantity which can not be determined and will change constantly. If a product is manufactured in a conventionalmechanical electrical control device, it will not be able to have the relevant control technology on the leading edge, andit will not be able to obtain a method that can correctly control its variables. Now, PLC technology can be widely usedin mechanical electrical control devices, and the problems above can be well solved. The effective control of the analog4 | Zhenguo Liu et al. Electronics Science Technology and Applicationquantity can make the digitization and the analog amount very well converted. In improving the production efficiencyof the control device, it can also reduce the impact of the analog quantity on the device.3.4 Select the right technical typeIn mechanical electrical control devices, there are many different types of technologies. Therefore, when applyingPLC technology, it is necessary to design a technology reasonably and select the most appropriate technology type. Thecorrect and reasonable technology type is the foundation before design. If you want to ensure the operation of PLCtechnology, you have to choose a good technology type before design. Compared with the distributed control system,the field bus control system is more applicable and more functional, simple in operation, simple in installation and lowin cost. Determining the type of PLC technology is a more systematic task. When selecting, it is necessary tocomprehensively consider the problems that may exist in various aspects. Therefore, we must carefully select atechnology type to ensure that PLC technology is more reasonable and scientific when applied[5].3.5 Design the communication networkThe use of PLC technology requires the design of a communications network so that the information between thevarious data can be transmitted normally. Technical personnel should take into account the environmental conditions inthe communications network when designing, and also need to combine the standards of the control device in operation,so as to scientifically and effectively design the communications network, so that the configuration performance of thecontrol device is higher, and the standard configuration during operation is satisfied. With the support of communicationnetwork, PLC technology can perfectly control the analog quantity and carry out effective variable prediction, so as torealize the control function of the control device.4. ConclusionGenerally speaking, PLC technology has been widely used in the mechanical and electrical control devices, andthis technology is still constantly updating and progresses, and plays a very important role in the control device.The basic configuration of PLC technology is a very small processor. At the same time, it combines many kinds oftechnology, such as automatic control technology, computer technology, relay control technology and so on.
