As more and more devices connect to the network and communicate with each other, we are accelerating into the era of “Internet of Everything”. The wireless transmission module is a key link between the IoT perception layer and the network layer. All device data generated

Traditional serial port equipment (such as RS485/RS232) has been widely used in daily production of enterprises. However, in the typical industrial automation field, long-distance monitoring often needs to be achieved from hundreds of meters to several kilometers. If you want to achieve wireless control signals

With the continuous innovation and development of the Internet of Things, global Internet of Things applications are showing an accelerated development trend. Intelligent data monitoring has become an indispensable part of industrial production. Wireless communication technology is used to transmit the collected data to the

The two-way transparent transmission of 4G network data means: a wireless terminal device that converts serial port data into IP data or converts IP data into serial port data and transmits it through the wireless communication network. Referred to as 4G DTU, most DTUs currently

DTU manufacturer-Chengdu Zongheng Intelligent Control Technology Co., Ltd. Chengdu Zongheng Intelligent Control is a high-tech enterprise specializing in the R&D and production of industrial-grade DTU, RTU, and industrial routers. It also provides a series of Internet of Things solutions. Since the establishment of the company,

DTU automation terminal is an Internet of Things wireless data transmission device that uses public operator networks to provide users with wireless long-distance data transmission functions. It uses high-performance industrial-grade 32-bit communication processors and industrial-grade wireless modules to operate in embedded real-time. The system is

Electric energy management and water meter reading and billing involving thousands of households and large consumers of electricity and water have become hot issues of concern and attention to the power department. For this reason, the rail-type 4G DTU-HZC4014 developed by Chengdu Zongheng Intelligent Control

As we all know, the Internet of Things is a network composed of millions of devices connected to each other through the network. The Internet of Things is a product that combines hardware and software. It can measure real-world information. and connect to the network

In fields such as industrial control, power communications, and smart instruments, serial communication is usually used for data exchange. The initial method used was the RS232 interface. Due to the complexity of the industrial site, various electrical equipment will produce a lot of electromagnetic interference

RTU (Remote Measurement and Control Terminal) is widely used in various industries such as building, HVAC, fire protection, water supply, petrochemical, environmental protection and other industries because of its telemetry, remote signaling, remote adjustment and remote control functions. However, as the control requirements increase, the

A relay is an electronic control device that has a control system (also called an input loop) and a controlled system (also called an output loop). It is usually used in automatic control circuits. It actually uses a smaller current to control a larger An

my country has heavy rainfall in summer, and flood control work in small and medium-sized rivers often becomes the focus of preventing floods during the rainy season. Therefore, in today’s highly developed Internet of Things technology, using Internet of Things technology to monitor small and
