Equipment control device for communication conversion based on wireless router

Abstract

The invention relates to an equipment control device for communication conversion based on a wireless router, and the equipment control device is technically characterized in that the equipment control device comprises a shell and a control circuit in the shell, and the control circuit comprises a network port-to-serial port module, an RS232 conversion circuit, the wireless router, a power supplymodule and a stm32 control system; wherein the internet access-to-serial port module is connected with the RS232 communication equipment through the RS232 conversion circuit and is used for convertingserial port information of the internet access-to-serial port module into RS232 communication information to be communicated with external RS232 communication equipment; wherein the internet access-to-serial port module is respectively connected with an external system internet access communication module and an external upper computer through a wireless router and is used for realizing interconnection and intercommunication between RS232 communication equipment and a terminal; and the internet access-to-serial port module is also connected with the stm32 control system and is used for realizing a function of converting serial port information into switching value information. According to the invention, compatibility and expansibility are high.

Description

technical field [0001] The invention belongs to the technical field of industrial control, and relates to a device control device for communication conversion, in particular to a device control device for communication conversion based on a wireless router. Background technique [0002] At present, the input and output switches of traditional external systems use RS232 or 485 for interactive control, or use a single network cable for interaction. With the development of technology, more and more devices use more reliable network cable transmission. However, when the control When the components form a huge system, the network ports of the equipment are not allocated enough, and it is often necessary to temporarily build a network. However, due to the lack of systematic planning, the temporarily built network is likely to cause a series of problems such as network congestion and broadcast storms. In the case of complex industrial sites, When the engineer debugs the equipment t...

[0002] At present, the input and output switches of traditional external systems use RS232 or 485 for interactive control, or use a single network cable for interaction. With the development of technology, more and more devices use more reliable network cable transmission. However, when the control When the components form a huge system, the network ports of the equipment are not allocated enough, and it is often necessary to temporarily build a network. However, due to the lack of systematic planning, the temporarily built network is likely to cause a series of problems such as network congestion and broadcast storms. In the case of complex industrial sites, When the engineer debugs the equipment through the computer, he uses a wired method to connect to the network. The connection process is very complicated. In severe cases, other wires will be scratched due to operational errors, causing the system to crash.
