Fig. 2 is the block diagram of taiwan area identifier disclosed in the utility model embodiment；
Fig. 3 is the drive circuit figure of pulse excitation signal disclosed in the utility model embodiment.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
Embodiment 1
The present embodiment discloses a kind of taiwan area identifier, applied in taiwan area identifying system as shown in Figure 1, the system bag
Include：Concentrator and user's table based on carrier communication, in addition to establish the taiwan area identifier communicated to connect with concentrator.Generally,
The corresponding taiwan area identifier of one taiwan area.
As shown in Figures 1 and 2, the taiwan area identifier of the present embodiment includes：Connect the Power convert of transformer terminal single-phase electricity
Module 1, its power output end are connected with carrier module 2 and main control unit 3；Main control unit be also associated with zero cross detection circuit 4 and
Circuit 5 occurs for pulse excitation, and zero cross detection circuit and pulse excitation occur circuit and be connected respectively with each phase line.
Wherein, concentrator is additionally operable to generate taiwan area identification instruction and referred to taiwan area identifier and the broadcast taiwan area identification of user's table
Order；Taiwan area identification instruction carries the output mechanism of pulse excitation signal and the response of user's table for being used for indicating taiwan area identifier
The relevant information of mechanism；And concentrator is additionally operable to after the pulse excitation signal that taiwan area identifier has conveyed all phases of wheel,
Collect the phase identification information that each user's table is drawn according to relevant response mechanism.Corresponding, the master control list of taiwan area identifier
Member detects the friendship of respective bus bars after carrier module receives the taiwan area identification instruction of concentrator broadcast in zero cross detection circuit
Stream electricity is when passing through zero-bit, encouraged according to the broadcasting instructions trigger pulse of concentrator occur circuit produce pulse excitation signal export to
Corresponding bus.
Optionally, in the present embodiment, concentrator is produced and exported each in taiwan area identification instruction carrying instruction taiwan area identifier
The time of phase pulse excitation signal and number of pulses, and taiwan area identifier produced by and export A, B, C three-phase pulse output
Time sequentially staggers.Such as：A phases 9:00-9:05, B phase 9:06-9:10, C phases 9:11-9:15, every pumping signal
Quantity can unanimously be 12000.
Corresponding, obtain what taiwan area identifier encouraged in the taiwan area identification instruction that user's table is sent out from concentrator
Time and the corresponding relation of each phase, zero passage number are then counted by several times in corresponding each period, then by the zero passage of the statistics
The number zero passage number intrinsic with each phase bus subtracts each other, judge remaining zero passage number whether with taiwan area identifier caused by arteries and veins
It is close to rush quantity, if close, draws the phase information of itself, and by the phase information write-in phase identification information of itself
Collected for concentrator.For example, if user's Table A is in A phases, 9:00-9:The zero passage number that period corresponding to 05 is counted
Should at 15000 times or so, wherein, if using existing mains frequency as 50Hz, in 5 minutes, the intrinsic mistake zero degree of the A phases bus
Number is 3000 times；In the period, because user's table C of user's table B and C phase in B phases is not present what taiwan area identifier increased newly
Pulse excitation signal, therefore, its zero passage number counted and itself intrinsic 3000 times.When taiwan area identifier produces in B phases or C phases
During raw pulse excitation signal, principle is similar, does not repeat.
In the present embodiment, optionally, include as shown in figure 3, circuit occurs for pulse excitation：
The triode Q12 that is amplified before the control signal CTL input pulse voltage devices T1 of main control unit, pulse voltage
