Problems solved by technology

In the MESH (wireless mesh network) network mode, the communication uses more network-wide broadcast messages. When there are many sites or the transmission density is high, it is easy to cause conflicts in message transmission, which affects the success rate and delay of transmission.
In the networking mode, the more nodes in the PLC network, the greater the absorption of PLC signals, which will cause more layers of the PLC network and increase the delay in sending messages.

Abstract

The embodiment of the invention provides a PLC sub-controller and a control system, and the PLC sub-controller comprises a first PLC module which is used for being connected with a first power line; a second PLC module which is used for being connected with a second power line; and a serial port module which is connected with the first PLC module and the second PLC module that communicate with each other through the serial port module. According to the invention, the time delay of a communication message is reduced, and the message sending success rate is improved.

Description

technical field [0001] The present application relates to the technical field of communication, in particular, to a PLC sub-controller and a control system. Background technique [0002] PLC (Power line Communication, power line carrier communication) is a communication technology for data transmission through power lines. This technology uses the existing power grid as a signal transmission medium, so that the power grid can carry out data communication while transmitting power. This method It can effectively monitor and control power equipment, instruments and household appliances in the grid. In the MESH (wireless mesh network) network mode, communication uses more network-wide broadcast messages. When there are many sites or high transmission density, it is easy to cause conflicts in message transmission, which affects the success rate and delay of transmission. In the networking mode, the more nodes in the PLC network, the greater the absorption of PLC signals, which w...
