Embodiment
The structure of detection device is as shown in Figure 1 in the present embodiment.Signal feedthrough is connected in parallel on the outlet of electric energy meter to be measured
End（2,4 ports）, for modulating default waveform signal and being coupled to electric energy meter and master switch in user room（It is spaced apart）Between
On circuit.The waveform signal is continuous high-frequency carrier signal, and signal frequency is shortwave, ultrashort wave frequency band signal, signal power
No more than 18dBm.Wave resistance device is the contactless wave arrestment of magnet ring, and the waveform transmitted on circuit is believed according to default time interval
Number implement wave arrestment（That is wave resistance device decaying to the sigtnal interval is equivalent to and an amplitude modulation has been carried out to signal.This resistance
Ripple processing belongs to the prior art）.This time interval can be uniform intervals or non-uniform spacing.In the present embodiment according to
Wave arrestment is implemented at default uniform 100ms intervals, and the waveform signal on circuit carries wave arrestment feature at this time.
Signal with wave arrestment feature will be passed to by power line in the user room being really directly correspondingly connected with electric energy meter,
The carrier signal of high frequency runs into breakpoint change in the instantaneous impedance can occur and cause the outside spoke of signal during being propagated along power line
It penetrates, thus is transmitted at the line break-point tests such as being spaced apart of user's indoor location, socket, switch in space, generate detectable nothing
Line signal, and then propagated to through wall outside user room.
Tester hold the sensing device further each family doorway to be measured one by one testing radiation come out wireless signal, in advance
If the wireless signal time span t received（Time span t is the total duration that sensing device further measures signal）, 0 is current time, solution
The variation characteristic of [- t, 0] period signal power is precipitated, radio signal power curve is formed, with default desired power curve
（Pre-programmed curve is the rule setting according to wave arrestment）Related coefficient is calculated after synchronization.The calculating of related coefficient is using vector X's and Y
Formula of correlation coefficient is as follows, and N is vector length：
This formula is statistics common-used formula, is seldom repeated herein, and the related coefficient value range calculated is [- 1,1].It calculates
The power average value of [- t, 0] in the period, then defines quantized value：
Quantized value=（1+ related coefficients）* power average value
Use linear function（Shaped like f (x)=ax+b）By quantized value scaling to [0,2* power average] section, such quantized value was both
It is related with power average and related with the correlation of curve.This quantized value represents the energy that each family is fed into feedthrough
Size and energy variation situation, because to target user（The user being connected directly with electric energy meter）Wave arrestment operation has been carried out, so
The variation of target user is most substantially i.e. big with the correlation of pre-programmed curve, and the average of target user also should be larger, so quantifying
Value it is maximum it is corresponding be exactly user that surveyed electric energy meter connects.Two are namely considered simultaneously because usually judging that target is used
Family can facilitate user to understand and use.
Sensing device further calculates final quantization value and is shown on screen, and tester records the final of all users to be measured
Quantized value, the user of registration maximum is the corresponding target user of electric energy meter.
Due to all posting corresponding family number mark below electric energy meter（Such as number）, it is electric that last test personnel will compare target
Whether the family number of the family number user corresponding with test gained on energy table is identical, if the two is identical, shows no error connection, on the contrary
Illustrate that mistake occurs for wiring（Visit one house after another）.
The present invention realizes connection box of electric energy meter inspection in the case where leaving user alone to greatest extent, and with higher
Reliability and practical value.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and modification, these improvements and modifications can also be made
Also it should be regarded as protection scope of the present invention.
