1. Industry background
With the current impact of the epidemic in various places, strengthen the scientific prevention and control of the epidemic, realize the joint epidemic prevention and control mechanism, and strive to promote the resumption of work and production. In view of the orderly development of the production work of the enterprise, the equipment debugging, monitoring and normal operation lora module guarantee of many industrial sites have also presented great challenges.
How to efficiently ensure the normal operation of industrial field equipment under the policy of the joint epidemic prevention and control mechanism? Remote debugging is particularly important.

On-site debugging, there are currently many pain points. The main pain points are:
l Low efficiency
l High cost
l Difficult to maintain
. . .
2. Solutions
Remote debugging
For many pain points of on-site debugging, remote debugging is adopted. It can effectively alleviate many pain points of current on-site debugging.
In terms of cost advantage, engineering advantage, system advantage and benefit advantage, it has been greatly improved. The overall advantages of remote debugging are obvious.

3. The principle of the scheme
Using 4G cloud data transmission radio, based on 4G network to break the distance limit. The 4G cloud data transmission station is connected to the equipment on the industrial site through serial communication (RS485/RS232). The data of the equipment debugging on the industrial site is received through the 4G cloud data transmission station, and then the data is automatically transmitted by the 4G cloud data transmission station through the 4G network. to the cloud.

The remote management center debugging computer is connected to the cloud online through the cloud virtual serial port software to realize the data exchange between the management center and the 4G cloud digital radio station of the remote industrial site, so as to meet the function of remote debugging of industrial field equipment.
Fourth, the program advantages
Application advantages of cloud virtual serial port:
Scenario 1 (the computer cannot access the Internet)
If the computer cannot access the Internet, it is necessary to realize remote access to configuration software or serial port software, using more than 2 devices, and the computer connects to the local cloud data transmission radio through RS485/RS232 to communicate with the remote cloud data transmission radio.
Scenario 2 (the computer can access the Internet)
The computer can access the Internet, use the cloud virtual serial port software, and use more than one device. SPI module The computer communicates directly with the remote cloud data transmission radio through the cloud virtual serial port.
