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 preset waveform signal and being coupled to master switch in electric energy meter and user room（It is spaced apart）Between
On route.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, is believed according to the preset time interval the waveform transmitted on route
Number implement wave arrestment（That is wave resistance device decaying to the sigtnal interval is equivalent to and has carried out an amplitude modulation to signal.This resistance
Wave processing belongs to the prior art）.This time interval can be uniform intervals, can also be non-uniform spacing.In the present embodiment according to
Wave arrestment is implemented at the preset uniform interval 100ms, and the waveform signal on route has wave arrestment feature at this time.
Signal with wave arrestment feature will be passed in the user room being really directly correspondingly connected with electric energy meter by power line,
The carrier signal of high frequency encounters breakpoint change in the instantaneous impedance can occur and cause the outside spoke of signal during propagating along power line
It penetrates, thus is emitted in space at the line break-point tests such as being spaced apart of user's indoor location, socket, switch, generate detectable nothing
Line signal, and then propagated to outside user room through wall.
Tester holds the sensing device in each family doorway to be measured wireless signal that testing radiation comes out one by one, in advance
If received wireless signal time span t（Time span t is the total duration that sensing device 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 preset desired power curve
（Pre-programmed curve is the rule setting according to wave arrestment）Related coefficient is calculated after synchronizing.The calculating of related coefficient is using vector X 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 calculated related coefficient value range is [- 1,1].
The power average value of [- t, 0] in the period is calculated, quantized value is then defined：
Quantized value=（1+ related coefficient）* power average value
Use linear function（Shaped like f (x)=ax+b）By quantized value scaling to [0,2* power mean value] section, quantify in this way
It is worth not only related with power mean value but also related with the correlation of curve.This quantized value, which represents, is fed into each family in feedthrough
Energy 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 target user variation most obviously i.e. it is big with the correlation of pre-programmed curve, and the mean value of target user also answer it is larger, so
Quantized value it is maximum it is corresponding be exactly user that surveyed electric energy meter connects.Two are namely considered simultaneously because usually judging target
User can facilitate user to understand and use.
Sensing device calculates final quantization value and is shown on screen, and tester records the final of all users to be measured
Quantized value, the maximum user of registration are 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 corresponding user obtained by the family number and test 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 a 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 improvements and modifications, these improvements and modifications can also be made
Also it should be regarded as protection scope of the present invention.
