Embodiment 1
Refer to Fig. 1, be the structural representation of intelligent electric meter batch meter system 10 1 preferred embodiment of carrier channel circuit described in the utility model and application carrier channel circuit.
In the present embodiment, described intelligent electric meter batch meter system 10 includes main website 11, RS485 communication interface 12, ammeter 13 and user interface section 14.Wherein, described main website 11 is connected with described ammeter 13 by described RS485 communication interface 12, is used for making this main website 11 can carry out communication by described RS485 communication interface 12 with described ammeter 13.Described main website 11 is connected with described user interface section 14 also by electric lines of force, is used for making this main website 11 can carry out communication by power carrier communication signal and described user interface section 14.
Further, described intelligent electric meter batch meter system 10 also includes relay 15, and this relay 15 can be built in described ammeter 13.In the present embodiment, described relay 15 includes closing a floodgate and two states of operating a switch, and is respectively used to the power carrier communication channel being turned on or off in described intelligent electric meter batch meter system 10.
Specifically, when described relay 15 is in "on" position, power carrier communication channel conducting in described intelligent electric meter batch meter system 10, can carry out power carrier communication by this power carrier communication channel between each parts of described intelligent electric meter batch meter system 10.Such as, by described power carrier communication channel, described main website 11 can carry out power carrier communication with described ammeter 13, it is also possible to carries out power carrier communication with described user interface section 14.
It should be noted that be cost-effective, production firm is typically equipped with power carrier communication module (PLC module) all without to described ammeter 13.Thus, described ammeter 13 typically cannot directly be connected with the communication of described user interface section 14.In this case, even if described relay 15 is in "on" position, between described user interface section 14 and described ammeter 13, also cannot directly carry out power carrier communication by described power carrier communication channel.Generally, power carrier communication signal can first be sent to described main website 11 by described user interface section 14 or described ammeter 13, described ammeter 13 or described user interface 14 it is sent to again, to realize the power carrier communication between described ammeter 13 and described user interface 14 via power carrier communication signal described after the transfer of described main website 11.
When described relay 15 is in and operates a switch state, the power carrier communication channel in described intelligent electric meter batch meter system 10 disconnects.Power carrier communication cannot be carried out by this power carrier communication channel again (between the most described main website 11, described ammeter 13 and described user interface section 14) between each parts of described intelligent electric meter batch meter system 10.
For the power carrier communication channel open in the described intelligent electric meter batch meter system 10 of maintenance, it is to avoid when described relay 15 is in and operates a switch state, the power carrier communication between each parts of described intelligent electric meter batch meter system 10 interrupts.In the present embodiment, described intelligent electric meter batch meter system 10 farther includes high pass filter 16.Described high pass filter 16 is connected across end of incoming cables and the leading-out terminal of described relay 15, for when described relay 15 enters and operates a switch state, a path that can pass through is provided for power carrier communication signal, make the power carrier communication channel open in described intelligent electric meter batch meter system 10, maintain the power carrier communication between described main website 11, described ammeter 13 and described user interface section 14.
Wherein, described high pass filter 16 can be X2 electric capacity, utilizes this X2 electric capacity, it is possible to achieve the power carrier communication channel open in described intelligent electric meter batch meter system 10.
Such as, shown in ginseng Fig. 2, it is relay 15 and a circuit connection diagram of an X2 electric capacity CX002 in this utility model one embodiment.Wherein, described X2 electric capacity CX002 is connected across the two ends of described relay 15.When described relay 15 is operated a switch, power carrier communication signal can send via coupling coil T901 and frequency selection circuit below, it is achieved communication after by described X2 electric capacity CX002 smoothly.
Further, when the capacitive reactance of described X2 electric capacity is 12.7 ohm, described power carrier communication signal is relatively low via its signal attenuation after described X2 electric capacity, does not affect communication effect.Therefore, described X2 electric capacity preferably capacitive reactance is the X2 electric capacity of 12.7 ohm.
Furthermore, it is necessary to supplement, in other embodiments, described relay 15 can also be to include a coupling coil 17.This coupling coil 17 acts on end of incoming cables and the leading-out terminal of described relay 15.With the high pass filter 16 in above-described embodiment similarly, this coupling coil 17 is for when described relay 15 is in and operates a switch state, the path that one permission power carrier communication signal passes through is provided, with the power carrier communication channel open in the described intelligent electric meter batch meter system 10 of maintenance, it is simple to the power carrier communication between described main website 11, described user interface 14 and described ammeter 13.
In sum, this utility model applies the relay 15 including described high pass filter 16 or described coupling coil 17 in described intelligent electric meter batch meter system 10, make the power carrier communication channel in this intelligent electric meter batch meter system 10 also can keep unimpeded when described relay 15 is in and operates a switch state, maintain the power carrier communication between each parts in this intelligent electric meter batch meter system 10, provide the user with conveniently, improve Consumer's Experience.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every under inventive concept of the present utility model; utilize the equivalent structure transformation that this utility model description and accompanying drawing content are made, or directly/be indirectly used in other relevant technical fields and be included in scope of patent protection of the present utility model.
