Computer information technology is also being used and popularized in various fields, and electronic control technology, as a new technology, has gradually developed in various fields and is deeply loved by the public. However, due to the technological development in China, electronic control technology needs to be improved and developed. This paper comprehensively expounds the computer electronic control technology and its application.
Keywords application of electronic control technology
With the advent of the network era, computers have entered thousands of households, and computer control technology was born. Electronic control technology is a complex technology involving electronic information, automatic control and other disciplines. The electronic control technology mainly realizes the effective adjustment of the system by collecting data, storing and processing effective data. This process can reduce labor costs and improve work efficiency and accuracy. Therefore, the role of computer electronic control technology in various industries can not be underestimated, and will be further developed and improved.
1 analysis of electronic control technology
Computer control system includes industrial control computer and production process, namely software and hardware. The hardware part consists of computer, process input and output interface, man-machine interface and external memory. , can realize the communication and control of the computer. Software system includes system software and application software, which is the sum total of computers that can complete various functional programs. From the function and purpose of the control system, the computer control system consists of operation guidance, direct digitization, supervision and control, distribution and field assembly.
1. 1 Introduction to Electronic Control Technology
Automatic control technology liberates human beings from the complicated working environment, and the equipment can consciously run according to the preset requirements, and can improve the control efficiency. Replacing some computer control devices with electronic control devices can realize effective control and adjustment of the system. The data transmission, receiving and processing functions of the computer can make the computer system run stably and efficiently. So as to realize the automation of the computer control system. The computer realizes the normal operation of the control system by controlling the two core modules of hardware and software.
1.2 electronic control technology course
In the 1960s, the United States took the lead in using computers in the safety monitoring system of industrial production, which enabled computer control technology to be applied. Due to the technical level at that time, the computer control system did not play a great role and could not meet the needs of industrial production. Stability is flawed and needs to be controlled by fictional means. With the progress of science and technology, semiconductor materials are applied to computer control system, which greatly improves the stability and reliability of computer control system. With the development of electronic control technology, DSC system appeared in 1980s, which promoted the development of computer technology. In 1990s, FCS system was born, which saved a lot of cost, and Internet system really appeared and was widely used.
2 technical status analysis
In the process of industrial production, there are many forms of interference factors, which lead to problems after computer assembly, affect the normal program and can not be used normally. There are mainly the following factors.
2. 1 interference source
High-voltage transmission lines, electrical equipment, radio waves and thunder and lightning can all produce electromagnetic fields, as well as electromagnetic waves generated by celestial bodies, which will cause spatial induction effect in the electromagnetic field propagation within its scope and then interfere with the computer control system. The process channel of the computer will also cause interference to the computer. By setting a common ground between the host and the process channel, the interference of the computer process channel can be effectively reduced. The AC power supply network used by the computer itself is also a factor of system interference. When the computer completes the power supply process, it will be disturbed by the frequency of the power grid. In the process of signal transmission, due to the existence of potential difference, the propagation of electric signal is affected by resistance, and the signal transmission is slow. When the current travels at a given speed, radio waves are generated in the line, and the propagation distance of the radio waves is relatively long. Because the terminal impedance and wave impedance of incident wave and reflected wave are inconsistent, incident wave and reflected wave will reflect when they reach the terminal, and reflection will occur frequently, which will affect the waveform and signal and cause pulse interference. The transmission speed of current wave and voltage wave also restricts the normal operation of computer control system.
2.2 methods to reduce hardware interference
Take corresponding solutions to the situation that affects the normal operation of the two core components of the computer: hardware and software.
In order to reduce hardware interference, the interference to the control system is determined and analyzed from three aspects: interference source, type and hardware type. According to different interference factors, different anti-interference methods are adopted to eliminate the interference of electromagnetic fields, process channels, radio waves and other factors, so that the anti-interference effect of computer hardware is significantly improved.
2.3 methods to reduce software interference
To reduce software interference, it is necessary to effectively control and deal with the interference filtering, PC value and trap of software system. When the computer system effectively processes numbers, filtering will interfere with the transmission of data signals, and the computer control system can weaken the influence of filtering by collecting signals many times. When the working order of computer CPU is destroyed, the PC value will be greatly affected. When the program fails, the instruction NOP can adjust the PC value of the correct track in time to avoid or weaken the interference of the PC value to the software system. In addition, the non-program interval of the software trap can be used to prevent the interrupt or reset command provided by the CPU from being forcibly guided to the designated position, thus effectively controlling the normal operation of the computer level.
3 application
3. 1 Used in mechatronics.
The integrated computer system of electronic and mechanical devices constitutes a mechatronics system, which perfectly combines electronic and mechanical control through the computer system, reducing labor costs, shortening working hours and improving work efficiency.
3.2 Application in industrial production
In actual production, the computer control system can be used to complete the control or operation of a dangerous and complex link by pre-setting the program, and it can also be used for personnel to control and supervise a certain process.
3.3 Application in agricultural production
By monitoring the running machine, we can set up programs, call in data and get information such as language according to actual needs. This information can be converted or transmitted by computer system software, so that users can operate conveniently according to the instructions.
4 Future development trend
With the rapid development of the network information age, the integrated technology integrating computer, automatic control and information will become intelligent, integrated and digital on the basis of stable and mature technology. Computer electronic control and technology will also be applied to people's work, study and life, and the progress of agriculture, industry, society, economy and country will be closely related to the development of electronic technology. On the basis of saving the cost of manpower, material resources and financial resources, it shortens the time and distance, so its application prospect is better.
5 conclusion
Today, the electronic control technology produced in the middle of the twentieth century is developing widely. The state should increase investment, formulate corresponding reform and adjustment measures, and actively encourage and popularize the development of electronic control technology. In the era of modern science and technology information with more extensive participation of computers, the computer electronic control system with higher performance, stability and intelligence needs to be further improved and developed.
