The principle of single chip microcomputer control relay
As an old industrial city, there are not many enterprises in embedded development and design of single chip computer in Zigong. Here we introduce the principle of single chip computer controlling relay. First, we look at the typical relay driving circuit diagram of relay. Such a diagram can be found everywhere on the network, and the circuit diagram of single chip computer in standard textbooks is generally a weak relay device. Most of them work at 5V or even lower. The driving current is below the mA level. It is obviously not feasible to use it in some high-power situations, such as controlling the motor. Therefore, there must be a link to link up, this link is just the same.

Single-sided, double-sided, multi-layer printed circuit board PCB
Printed Circuit Board, PCB abbreviated as printed circuit board, is an important basic component in electronic products. It is widely used in consumer electronics, automotive electronics, industrial automation control, communication equipment, military electronic equipment and aviation, and aerospace electronic systems. Etc., printed boards can be used in almost all electronic products. The design and manufacturing quality of PCB directly affects the quality and cost of electronic assembly process and electronic whole machine products, and sometimes becomes the key to affect the quality of electronic product systems. Therefore, it has received extensive attention from the electronics industry at home and abroad.

Mechanical time relay principle
There are many different types of relays. Time relays are one of the more common types. They use time setting to control the electrical components of the circuit that turn on or off the voltage and current. When the relay working coil is driven to give a control current, the relay will pick up. Its contacts will be turned on or off. In control circuits, relays are often referred to as contactors. Mechanical time relay time relays are widely used in electronic equipment such as remote control, communication, automatic control, etc., and are the most important control components. Commonly used time relays are mainly air damping type, electric type and electronic type. Time relays are also widely used in production equipment.

TDK Introduces new temperature and pressure sensors
Modern industrial automation control increases the accuracy requirements, and the temperature sensor's operating temperature range, accuracy, and reliability requirements are also increasing. TDK has introduced a series of new products to meet market requirements. To monitor the control modules of the equipment and the various parameters of the surrounding environment, the most basic temperature and pressure monitoring will become a common trend. For example, temperature monitoring of the main chip, IGBT, MOSFET, and diode can prevent the continuous rise of the operating temperature during continuous operation and cause the failure of the main core electronic components.

Zigong Pavilion simulates dinosaurs and lanterns
The 17th Western Expo opened. The Zigong Exhibition Hall at Hall N201 in Hall 2 of the Western International Expo City Exhibition Center was unveiled. At the same time, the city set up a 432-square-meter Zigong City publicity advertisement for the first time in the advertising space of the curtain wall of Hall 3. Seen at the scene, you can see the Zigong Pavilion, which is surrounded by white bases and beautiful ribbons. You can see the modern style of simplicity, light and color, and compatibility. The theme slogan “Building a National Demonstration Zone for the Transformation and Upgrading of Old Industrial Cities” and “Building a National Cultural Export Base” is striking.
