Problems solved by technology

[0002] At present, in the field of solar power generation, simplex passive communication is generally used because the automation degree of the solar energy system is not high in the early stage. With the requirement of communication, in order to improve the transmission rate, duplex communication is adopted again, but because the conversion efficiency of the solar energy system is not high , the on-site electrical parameters are often very unstable, resulting in frequent failures in the transmission of sensitive electronic components in duplex communication, resulting in the failure of normal communication due to unprepared transmission of a large amount of communication data

Embodiment Construction

[0007] The present invention will be further described below via accompanying drawing:

[0008] as attached figure 1 As shown, the duplex communication method for solar power generation has a built-in programmable logic controller PLC2 with a voltage stabilizing circuit, plus a built-in database buffer device 3 with a message queue that shares memory with the duplex communication method for solar power generation with a voltage stabilizing circuit . When duplex communication is required, the message queue of the database buffer device 3 is driven through the built-in programmable logic controller PLC2 with a voltage stabilizing circuit, and then the priority of the message queue is used to set the operation of the voltage stabilizing circuit in order to ensure solar power generation. The electrical parameters of the duplex communication method are stable. The defect of frequent failures in the transmission of sensitive electronic components 1 in duplex communication is avoid...

Abstract

The invention discloses a duplex communication method for solar power generation. When the duplex communication is required, a programmable logic controller (PLC) provided with a built-in attached voltage stabilizing circuit drives message queues of a data base buffer device, and by means of the priority levels of the message queues, the operation of the voltage stabilizing circuit is sequentially set so as to guarantee stable electric parameters of the duplex communication method for the solar power generation. According to the duplex communication method for the solar power generation, the defect that faults often occur during the process of sensitive electronic component transmission in the duplex communication is overcome, and the normal duplex communication is achieved.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a duplex communication method for solar power generation. Background technique [0002] At present, in the field of solar power generation, simplex passive communication is generally used because the degree of automation of the solar energy system is not high in the early stage. With the requirement of communication, in order to increase the transmission rate, the duplex communication method is adopted again, but due to the low conversion efficiency of the solar energy system , On-site electrical parameters are often very unstable, resulting in frequent faults in the transmission of sensitive electronic components in duplex communication, resulting in the failure of normal communication due to unprepared transmission of a large amount of communication data. Contents of the invention [0003] The invention provides a duplex communication method for solar power gen...
