With the continuous development of computer application and network technology, the risks and losses of information security are increasing exponentially, which leads to the increasingly prominent network security problems. According to the current situation of network security, this paper puts forward the idea of using network security controller to help solve network security problems, and

Temperature control software is a kind of industrial control software, which has strict requirements for temperature data acquisition. In order to accurately realize the acquisition and representation of temperature data, the main characteristics of temperature control data are summarized, and the Modbus protocol and address specification are introduced. On this basis, the communication mode between

At present, the sensor has become one of the widely used magnetic sensors. As the three pillar technology of modern information society, sensor technology has been widely used in various fields of national economy. This paper briefly introduces the effect of the sensor, and designs the automatic controller circuit of the toilet based on the

The hardware is based on dual tone multi frequency (DTMF) and programmable logic device (CPLD). An elevator automatic monitoring and alarming system is developed, thermostatic element and the monitoring controller in the system is designed. The designed controller can monitor and alarm the parameters of the door switch, car lighting, safety clamp clamping force and

With the rapid development of science and technology, all kinds of mechanical equipment have higher requirements for the reliability of generator controller. By means of stress damage analysis, fault analysis and technical condition decomposition of products based on fault prediction technology, and relying on physical simulation analysis, the reliability of generator controller can be combined

With the rapid development of science and technology, social productivity is also gradually improving, people also put forward higher requirements for machine tool control system, so we should focus on the analysis of the application of programmable controller in machine tool control system. 　　This paper summarizes the characteristics of the programmable controller and the problems

The article mainly analyzes and elaborates the important modules of the broadcast transmitter monitoring system from the aspects of the acquisition controller, the acquisition controller function and the transmitter’s requirements for the acquisition controller. The automatic monitoring system software is designed by the multi-layer C/S B/S hybrid structure. The real-time monitoring software adopts the C/S

Because of the limitation of the low level of science and technology and the high cost of photovoltaic power generation, the application effect of photovoltaic power generation system is unsatisfactory for a long time, which affects its promotion and development to a large extent. Therefore, in order to promote the improvement and development of photovoltaic

The application of automatic humidity controller in programmable power system makes precise quantitative control of humidity regulating equipment such as dehumidifier and drying lamp in substation, so as to avoid the phenomenon that artificial control is not timely and the use time is too long. It not only improves the qualified rate of environmental humidity

This paper presents a neural network direct self-tuning PID controller. Its main feature is that the control structure no longer contains an independent PID controller, but integrates the neural network and the PID control law. The learning algorithm of the neural network controller and the stability analysis of the control system are given. The simulation
