rtu control system The rtu control system is referred to as rtu, and the Chinese name is: remote telemetry terminal. It is a device that mainly integrates remote control and data transmission. It usually has DI (switch input), DO (switch output), AI (analog input), AO

rtu control system application in oil fields In order to realize single well automation and intelligent drainage and production, an oilfield RTU control was developed with the currently internationally accepted programmable controller PLC as the core and easy to configure on-site automation control, equipped with

Some readers have never been exposed to a microcontroller and have a vague concept of what a microcontroller is. In this issue, we have specially launched this introductory article to let you know what a microcontroller is like and what types it is. How does

ZHC1921 developed by Zongheng Intelligent Control is a device that supports modbus rtu to tcp protocol and supports mutual conversion. The network type of this product is Ethernet. If customers need other network type equipment to support this function, it can be customized! Product function

There are many forms of antennas. To facilitate discussion, the following introduction will classify antennas according to different situations. They are classified according to seven aspects: work nature, use, characteristics, current distribution, wave band, and appearance. Antenna classification 1. Classification according to nature of work

Chips have always been our hot topic and concern. Chips are also a dazzling crown at the top of the world’s technology. Whoever controls the chip can have a say in the technology world, because the production of chips involves many technologies, such as semiconductors.

First, what is an IoT chip? We know that there are many types of chips. So what is an IoT chip? First, we need to know what the Internet of Things is. Simply put, a network of interconnected things. Its core is still the Internet,

ZHC2931 is an upgraded version of a multi-functional integrated controller based on Internet of Things technology. Users of the Internet of Things control system implemented through this controller can realize remote monitoring of terminal equipment. Provides 1 serial port (RS485/RS232), 2 DI, 1 DO and

zigbee? Applications of Zigbee Zigbee is a low-power personal area network protocol based on the IEEE802.15.4 standard. The technology specified under this agreement is a short-range, low-power wireless communication technology. The name comes from the eight-character dance of bees, because bees rely on the “dance”

The wireless data transmission module is a modular product of the data transmission radio station. It refers to a high-performance professional data transmission radio completed with DSP technology and radio technology. The use of digital radio stations has evolved from the earliest push-button telegraphs, telegraphs,

In view of the necessity of converting serial port data into network data during Internet of Things communication, a design method of data transmission unit is proposed. The serial data interface is the commonly used RS-232 and RS-485 interface, and the network data interface is

1. Application block diagram The DTU application framework diagram is shown in Figure 1. DTU communicates with node C through wired low-speed mode. Finally, DTU summarizes the data and sends it to the business platform server. The data uploaded by node C is called business
