On September 4, Guangyuan Municipal Party Committee Secretary He Shuping and Datang Guiguan Power Chuanhui Company Party Committee Member and General Manager Zhang Xianming visited Jiangsu Meimiao Energy Storage Technology Co., Ltd. and held discussions with Meimiao Energy Storage Chairman Shen Min on issues such as

Since the school's campus network server is relatively old, the development board cannot use DHCP directly. So there are two solutions: 1. Before connecting to the development board, first connect to a switch, and then connect the interface that comes out to the development board. 2.

A 10,000 mAh power bank can store 0.037 kWh of electricity at a time, which can fully charge 2 mobile phones. Have you ever seen a giant power bank that can store 8,000 kWh of electricity at a time? In the park of Hubei Changjiang Electric Co., Ltd., an all-iron liquid flow energy storage system with a storage time of

In addition to ladder diagrams, PLC programs also have FBD function blocks as instructions, which generally have background DBs. The PLC counter instruction enables it to count internal program events and external process events, thus saving the use of external counters. Each counter uses a structure

He Wenying, our reporter Recently, the research team of Qingdao Institute of Bioenergy and Process Technology of Chinese Academy of Sciences has made new breakthroughs in the field of all-solid-state lithium batteries, and its results have been published in the international academic journal Nature-Energy. Professor Zh

Electromagnetic interference (EMI) refers to the interference of unintended electromagnetic radiation from the outside world. This interference can interrupt, hinder or degrade the performance of the circuit. In today's portable consumer electronic device design, space has become the first factor. Designers often ne

We all know that PLC control is used for actual engineering projects, so the level of system design will directly affect the entire control system and the operating reliability of the equipment! Do you agree? So how can we design a control system that is stable in operation, reliable in action, safe to use, eas

1 IMX6ULL SPI controller Chapter 20 of NXP's 6ull reference manual introduces the SPI controller, Enhanced Configurable SPI (ECSPI). 1.1 Features ①. Full-duplex synchronous serial interface. ②. Configurable master/slave mode. ③. Four hardware chip select signals, support multiple slaves. ④. There is a

Cerence Inc., AI for a world in motion, announced that Volkswagen Group has deployed Cerence Chat Pro and integrated the unique intelligent automotive-grade ChatGPT application into European models through a cloud update, marking the first time the solution is available to drivers. Previously, at CES 2024, C

Today, follow the steps of the editor and let's find out. In the picture, we can see that the main components of the electric air compressor include: motor , oil filler, air compressor body, oil cooler, cooling fan, air intake connector, scheduling connector, etc., which together form the air comp

The main function of uboot is to guide the kernel to start. This article introduces how to implement this function and form a simplest system, which not only requires porting uboot, but also porting the Linux kernel and creating a root file system. First, we partition the nandflash and plan where each file is s

Comparing domestic and foreign motors, we can directly feel the gap in many advanced process technologies between Chinese and foreign companies in motor manufacturing. Whether it is the advanced level of equipment or their way of thinking and specific practices, they are all worth learning from. The following is a b
