Description
Technical field
The utility model designs a kind of equipment, and in particular to a kind of to allow power line communication setting across ammeter or air switch
It is standby, belong to power line communication technology field.
Background technique
Power line communication refers to a kind of communication mode using power line transmission data-signal.The technology is carrying information
High-frequency signal load on electric current, be then transferred by wires, receive the modem of information again high-frequency signal from electric current
It separates, and is transmitted to the terminal devices such as computer, to realize that information is transmitted.The transmission technology of dedicated for electric line communication is orthogonal
Frequency division multiplexing is exactly superimposed together data-signal and electric power signal.Our electricity usually are all alternating currents, and frequency is
50Hz, power line communication are exactly to be superimposed with data-signal on the basis of alternating current.Because frequency data signal is all very high
（10MHz is even higher）So if will not be had an impact to power transmission using suitable means.There is no any Signal averaging
Ac power waveform and to be superimposed with the later ac power waveform of high-frequency data signal as depicted in figs. 1 and 2.
The equipment of power line communication is realized Homeplug, Homeplug need to match use, can two Homeplugs match, can also
Multiple Homeplug pairings.Assuming that Homeplug A, B are a pair, carried out data transmission using Homeplug, including three steps：
（1）Data equipment A network interface is inserted into cable one end, the other end is inserted into Homeplug A network interface；
（2）Homeplug A is inserted at data equipment A in power outlet, Homeplug B is inserted in power supply at data equipment B and is inserted
On seat；
（3）Homeplug B network interface is inserted into cable one end, the other end is inserted in data equipment B network interface, and connection is completed.
Basic model is exactly：
Data equipment A<=>Homeplug A<=>Electric wire<=>Homeplug B<=>Data equipment B
Since ammeter can filter out the high-frequency signal being superimposed upon on power line, air switch can also allow the high frequency on power line
Signal is substantially decayed.Therefore, power line communication can not be used across ammeter, also result in power line communication speed across air switch
Rate sharply declines, and nominal transmission rate is not achieved.It need to be in the same sky of the same ammeter so matching the Homeplug used
In the power outlet of air cock connection, it could work normally, reach nominal transmission rate.
Utility model content
The purpose of the utility model is to provide a kind of equipment for allowing power line communication to cross over ammeter or air switch, this is practical
It is novel that power line communication is allowed to can be used normally across ammeter or air switch, the Homeplug for allowing pairing to use different ammeters,
It is worked normally between the power outlet of different air switches, reaches nominal transmission rate.
The purpose of this utility model is achieved through the following technical solutions, and one kind allows power line communication to cross over ammeter or sky
The equipment of air cock, including apparatus body, characterized in that the identical Homeplug of several structures is equipped with inside the apparatus body
Module is connected between Homeplug module by cable；Several Homeplug module arrangements are in corresponding ammeter or air
At switch.
Preferably, when needing to carry out power line communication across two different ammeters or air switch, in ammeter or sky
The new equipment laid at air cock uses two Homeplug modules, and the power supply port of each Homeplug module passes through power supply line and one
The outlet of ammeter or air switch connects, and the data port of two Homeplug modules is directly connected to inside equipment using cable.
Preferably, multiple when needing to cross over（Greater than two）When different ammeters or air switch carry out power line communication,
The new equipment laid at ammeter or air switch uses multiple Homeplug modules, and the power supply port of multiple Homeplug modules passes through electricity
Source line is connected with the outlet of multiple ammeters or air switch respectively, and the data port of multiple Homeplug modules is inside equipment and line concentration
The data port of device module is connected by cable.The Alternating Current Power Supply mouth of alternating current-direct current voltage changing module is inside equipment and Homeplug
Power supply port connection, the direct current output mouth of alternating current-direct current voltage changing module and the direct current supply mouth of hub module connect.
Preferably, alternating current-direct current voltage changing module, the Alternating Current Power Supply mouth of alternating current-direct current voltage changing module are equipped with inside the apparatus body
Connected inside equipment with the power supply port of a Homeplug, the direct current output mouth of alternating current-direct current voltage changing module and hub module it is straight
Flow power supply port connection.
Compared with prior art, the utility model has the advantages that：
First, the utility model solves the problems, such as that power line communication can not cross over ammeter and air switch normal use.
Second, the utility model no replacement is required original ammeter, air switch and Homeplug, by former ammeter or air
A new equipment is connected at switch, is allowed first wife to work normally the Homeplug used across ammeter or air switch, is reached nominal
Transmission rate, saved equipment investment.
