Industrial serial server can control other serial ports and network-connected devices
Industrial Serial ServerIndustrial serial server can control other serial ports and network-connected devices, and can access the system console of network devices to monitor and control their functions.
Industrial SwitchThe industrial switch can control PCs and servers, and can only switch between connected network devices.
different functions
[Industrial serial server] The role of the industrial serial server is to realize the networking equipment from the serial port to the Ethernet, which can transmit data between the Ethernet LAN and the serial port (COM port) of the computer or device. sx1276 lora module The main purpose is to allow serial devices such as printers, scanners, or climate control systems to be used on a network without relying on a computer's serial port for the connection. This way, any serial device can be connected to the network and accessed from anywhere, including the internet.
Industrial switchIndustrial switch is also called industrial Ethernet switch, which is suitable for server control in the same room or around the world. Its main function is to expand network signal equipment, and it is an Ethernet switching device for industrial control. bluetooth module nrf52832 Because of the adoption of network standards, it is open, widely used, and cheap. It uses transparent and unified TCP/IP agreement. Networking has become the main communication standard in the field of industrial control.

Hotel circuit intelligent control scheme, saving time, effort and cost!
The hotel industry has a long history of development, and hotels are constantly evolving. With the development of modern Internet of Things technology, the services of the hotel industry are also iterating and becoming more "smart": automatic light control, automatic curtains, temperature and humidity Flexible services such as control bring more warm enjoyment to each guest.
In fact, many hotels still use traditional circuit control methods, such as some traditional key switches, circuit breakers, etc. These methods have some disadvantages in the era of intelligence:
1. The operation is troublesome, and the customer needs to be close to the operationbluetooth low energy module
2. The circuit wiring is cumbersome and the distribution of lines varies
3. Electrical appliances cannot form a centralized management system
4. Unable to monitor power consumption and avoid waste of power
Optimization method100 meter bluetooth module
The gateway is used to remotely intelligently control the circuit switches of hotel facilities (take the Ebyte E870 series as an example), realize the operation of electrical equipment on the cloud, and accelerate the construction of hotel informatization, which can reduce the management cost of managers and improve management effects. It can also bring customers more intimate service.

4G wireless smart meter reading, more than a little easier
With the development of the Internet of Things, people's lifestyles are changing subtly, and work and life are gradually shifting from traditional offline to online. More and more companies are also adopting offline and online management models to improve their business Viability and competitiveness,Industrial Router/Gateway meter reading is no exception.
In daily property management, meter reading is a tedious task, and the traditional meter reading mode has many disadvantages:
1. Manual meter reading is troublesome and error-prone
2. Dispersion distance is long and time-consuming
3. The efficiency is too low and the labor cost is too high
Aiming at the defects of the traditional meter reading method, the 4G wireless smart meter reading system came into being. Based on the 4G communication technology of the three major operators, it has the advantages of fast transmission speed, low communication cost, Single serial port server convenient installation and low cost, no need for additional wiring, and stability. Strong, not limited by distance and many other advantages, the use of 4G wireless meter reading solution can effectively reduce labor costs and improve the accuracy of data statistics.
