Interrogate the situation that the communication modes of module are disturbed respectively by cable signal interference or wireless signal.Although this scheme can improve communication
Reliability, but testing efficiency is low during module production, because module has power line carrier and wireless communication function simultaneously, surveys
Switching channel is needed to test carrier communication and wireless communication respectively during examination, causes module testing efficiency low, and each passage
Communication success rate can not count.
Utility model content
Technical problem to be solved in the utility model is the present situation for the prior art, and carrier wave can be counted by providing one kind
The PLC bimodulus Module Automatic Test Systems of channel module and radio channel module communication success rate.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of PLC bimodulus module is tested automatically
System, it is characterised in that：Including host computer, MCU, carrier channel module, radio channel module and for communicating with electric energy meter
PLC bimodulus modules, the host computer are connected with MCU, and for transmitting signal of communication to MCU, the MCU connects radio channel respectively
Module and carrier channel module simultaneously pass through any of which channel module transmission signal of communication, and the PLC bimodulus module connects electric energy
Table, the PLC bimodulus module are communicated to connect with any channel module, and the signal of communication transmission feedback transferred according to MCU is received
Signal and judge whether that switching channel module is needed to communicate.
In said program, the MCU is connected by I/O interfaces with radio channel module and carrier channel module respectively.
Further, the electric energy meter is connected by I/O interfaces with PLC bimodulus modules.
Further, the radio channel module is connected with the first antenna for communication.
Further, the PLC bimodulus module is connected with the second antenna, communicates for wireless module.
Preferably, the MCU is STM32F103RBT6.
Compared with prior art, the utility model has the advantage of：Carrier channel module or radio channel module send logical
Believe signal, PLC bimodulus modules receive data frame and carry out feedback Echo Frame, and channel module judges whether to switch according to frame condition is responded
Passage communicates, and system can automatically be tested according to the testing time of setting, communicated, carried using PLC bimodulus modules
High communication reliability, module testing is efficient, and host computer can Echo Frame and data frame compare statistics carrier wave respectively and lead to
The communication success rate of road module and radio channel module.
Description of the drawings
Fig. 1 is the utility model embodiment host computer communication structure figure；
Fig. 2 is the utility model embodiment electric energy meter communication structure figure.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing embodiment.
As depicted in figs. 1 and 2, a kind of PLC bimodulus Module Automatic Test System includes host computer 1, MCU2, carrier channel mould
Block 3, radio channel module 4 and the PLC bimodulus module 7 for communicating with electric energy meter 6, wherein host computer 1 are connected with MCU2, are used for
Signal of communication is transmitted to MCU2, MCU2 connects carrier channel module 3 and radio channel module 4 by I/O interfaces and passes through respectively
Any of which channel module transfers signal of communication, 4 other end of radio channel module connection first antenna 5；PLC bimodulus module 7 is logical
It crosses I/O interfaces to be connected with electric energy meter 6,7 other end of PLC bimodulus module connects the second antenna 8, PLC bimodulus module 7 and any passage
