In addition to the momentum and pressures created by political strategies such as the Kyoto Protocol, the increasing costs of many forms of energy and the search for "cleaner" sources of power are driving interest in alternative energy sources such as solar. Many new designs are emerging to use these energy sources most effectively and efficiently. ......
Infrared sensors include optical systems, detection elements, and conversion circuits. Optical systems can be divided into two types: transmission and reflection according to their structures. Detection elements can be divided into thermal detection elements and photoelectric detection elements according to their working principles. The most commonly used thermal element is thermistor. Thermistors are irradiated by infrared radiation......
During the operation of the escalator, the flow of customers varies greatly at different times. Sometimes there may be no one riding the escalator. Since the arrival of customers is random, it is impossible to stop the escalator when no one is riding. The escalator without speed control can only run at the rated speed, which is very unsustainable....
Four circuits of monostable trigger composed of 555: The circuit shown in Figure (a) is a typical monostable mode circuit. When the external pulse is added to the 2nd pin of 555 through the C1 and R1 differential circuit, the negative pulse (<1/3VDD) sets the 555, and the 3rd pin outputs a temporary stable pulse width td=1.1RC. Figure (b) is similar to Figure (a), but it has two output terminals. C passes......
Wireless sensor networks have a wide range of applications. Wireless sensor nodes are generally powered by batteries, have simple hardware structures, small communication bandwidth, and short point-to-point communication distances. Therefore, limited working time and short communication distances are two major bottlenecks of wireless sensor networks. If long working time and communication are required......
Introduction With the improvement of living standards, the demand for intelligent furniture has gradually emerged, and the application of temperature, humidity and other data collection has begun to show an increasing market potential. In this article, Silicon Labs' Si7001 temperature and humidity sensor, C8051F985 low-power MCU, CP2403 LCD driver, and LCD display are used to build a......
Abstract: Due to the nonlinear time-varying characteristics of the asynchronous motor soft start process, it is difficult to achieve the ideal control effect using the traditional PID control method. In order to greatly reduce the current during the AC motor startup process, a new fuzzy PID soft start controller is designed in combination with intelligent control theory. By adjusting the current size......
IntroductionSensor testing technology is developing towards multifunctionality, miniaturization, intelligence, networking and wireless. As an emerging technology, self-organizing wireless sensor networks (Self-Organizing Wireless Sensor Networks) are currently a hot topic of foreign research. They are widely used in military, environment, health, family, business......
1. Overview The industrial computers, various communication modules, security devices and field measuring instruments in the intelligent instrument control system mostly use the integrated circuit combination of electronic devices. These micro-electric devices generally have fatal weaknesses such as low insulation strength and low surge resistance. They are often damaged by lightning in thunderstorm seasons, causing several......
In order to improve energy efficiency, countries are accelerating the construction of smart grids and vigorously promoting smart meters to meet the growing demand for electricity. While rapidly promoting the application of smart meters, meter developers, manufacturers who provide them with components, and even end users are also paying attention to technologies and products that can make smart meters more energy-efficient, so as to......
DS18B20 digital thermometer is a 1-Wire, or single bus device, produced by DALLAS. It has the characteristics of simple circuit and small size. Therefore, it can be used to form a temperature measurement system with simple circuit. Many such digital thermometers can be hung on one communication line, which is very convenient. Features of DS18B20 products (1) Only one terminal is required......
Abstract: Before finalizing the car, the test data of each part must be analyzed. At present, many sensors in the car are directly connected to the data collector and the car battery with wires. A large number of wires will directly affect the test environment. Based on this, a new voltage-regulated power supply and communication subsystem is designed to replace the wires and minimize......
Abstract: To adapt to the application of low voltage and low power design, an ultra-low power supply voltage rail-to-rail CMOS operational amplifier is designed. An N-channel differential pair and a P-channel differential pair with common mode level shift are used to achieve rail-to-rail signal input. When the common mode level of the input signal is in the middle, the input common mode level of the P-channel differential pair will be......
Due to its high precision, high speed, high efficiency, safety and reliability, CNC machine tools are rapidly gaining popularity in enterprises in the process of updating manufacturing technology and equipment. CNC machine tools are an automated machine tool equipped with a program control system, which can make the machine tool move and process parts according to the programmed program. It integrates machinery, automation......
1. Introduction The instrument control system of the synthetic rubber coagulation unit of Yanshan Petrochemical Company was originally composed of conventional instruments, and all of them were old instruments replaced from other devices, with a high failure rate. In order to improve the level of automation and enhance the reliability of the instrument control system, we transformed it, eliminated all conventional instruments in the control room, and replaced them with......
Since waste incineration power generation technology has the characteristics of high efficiency in treating domestic waste, saving energy, short construction period and environmental protection; at the same time, circulating fluidized bed boilers (CFBB) have the characteristics of high combustion efficiency, strong adaptability and high combustion intensity, it is a new boiler worthy of adoption......
