[Prior Art] Head A 'The power company's power-limiting management information system in the high-voltage feeder part, its attribute data has reached a certain degree of accuracy, but the correlation between the transformer and the power supply users, there is still a considerable degree of inconsistency, resulting in The construction power failure notifies the user of the operation error, which affects the relationship between the company and the user, and even compensates the user equipment for burning. Investigating the relationship between the user terminal and the transformer on the power supply side by power failure will not only cause inconvenience and loss of the user's power outage, but also easily lead to user complaints and relatively reduce the company's electricity fee income. However, the current survey was conducted by visual inspection and could not obtain completely correct information. Therefore, how to quickly and effectively investigate and verify the user-transformer-related data is an urgent problem to be solved. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a detection apparatus, method and computer program product capable of accurately interpreting a power phase using power line carrier technology. The power phase detecting device of the present invention performs voltage phase identification on a carrier of a power line between a power supply terminal and a user terminal. The power phase detecting device comprises: a money processing electrometer-pure module, the carrier processing circuit obtains a carrier signal from the user end and demodulates it into a signal to be tested; the phase 201100812 bit 疋 module is considered to be The signal is measured at a zero crossing point of a predetermined period and is separated according to the threshold value of the different dust phase thresholds to generate different coded signals. The power phase detection method of the present invention performs voltage phase determination on a carrier of a power line between a power supply terminal and a user terminal. The method for detecting the power source position includes the following steps: (4) obtaining a pre-signal from the power supply terminal; (8) obtaining a carrier signal from the user terminal and demodulating it into a signal to be tested; and 0) calculating the first zero crossing point of the predetermined number in a predetermined period, and obtaining the signal to be tested from the carrier processing circuit Calculating a second zero crossing point in the same period, and dividing the count value of the zero crossing point of the signal to be tested according to the threshold value of different voltage phases to generate different encoded signals.

It can be quickly and effectively reviewed at any time. At the same time, it can be applied to the repair of low-voltage accidents. The on-site personnel can quickly and correctly detect the relevant transformers to avoid affecting other users' power consumption due to misjudgment. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figure Bu, the power supply mode of the general power company is a main feeder 5 extended by the power company's change 201100812 electric station 50, and then the main feeder 5〇1 is supplied to the power supply terminal 51 (voltage device) of a plurality of different regions. The power supply terminals 51 are connected to different customer terminals 52 with diverging power lines 53.较佳 较佳 A preferred embodiment of the power phase detecting method of the present invention utilizes a power phase detecting device 61 of the power supply terminal 51 to be electrically connected to a power supply _ 51 (voltage device) to provide a predetermined signal, such as a voltage signal, and another operation. The person uses the power phase detecting device 62 of a user terminal 52 to electrically connect the power line 53 of the user terminal 52 and receive the signal to perform voltage phase identification with the test number of the user terminal 52. The technical principle of the present invention is explained. as follows. The voltage signal of 220 volts is divided into three voltage phases including VAB, VBC, and VcA. When the voltage supplied by the power supply terminal 51 is 2 volts, the 220 volt power phase detection method of the present invention is at the power supply end. The "AB phase" of the 51 (transformer) is connected to the power phase detecting device 6 of the power supply terminal 51. The predetermined signal % of the "AB phase" output from the power supply terminal 51 is used as a comparison reference with the signal to be tested using the two terminals 52, in order to avoid The noise interference is modulated into a modulated signal fed into the power line. The power phase detecting device 62 of the user terminal 52 obtains the predetermined signal VAB from the power supply terminal 51. Then, the modulated signal is obtained from the user terminal 52 and demodulated into a signal to be tested, such as "B of the user terminal 5". The c phase "rounds up as the signal to be tested VbC, and then calculates a predetermined zero crossing point u of the predetermined signal vab at a predetermined period and a second zero crossing point t2 of the same period of the signal to be tested, and according to the threshold of different voltage phases The T2 and T3 values encode the count values of the zero crossings of the signal to be measured to produce different coded signals. The power phase detecting device 62 of the user terminal 52 has a counter and a code 201100812 code module, and the power phase detecting device 62 simultaneously sends a start signal to the counter at the start time t〇 of receiving the predetermined signal vAB. Start counting, assuming that the counter counting rate is χΚΗζ, that is, every 丄 ms count - A: times 'calculated by the 6 GHz power line sine wave signal, each time the power line signal phase advances about ^ degrees ' with the predetermined signal Vab as an example, - The periodic signal (the fourth zero-crossing point (four) to 帛2 * the rising edge of the material point) needs about 16.6, the secondary count 'that is, the starting time to the full-cycle time t1 count value is i6 L times, and the user terminal 52 The signal to be tested obtained by the power phase detecting device 62 is the first after the start time tG! At the time t2 of the rising edge of the zero crossing point, a stop signal is sent to stop the counter, and the last digit of the counter is recorded, and the signal I to be measured is counted as 5.5, waiting for the count value. The measurement signal Vca is taken as an example, and the count value is (1) times, thereby determining the phase relationship between the power signal used by the user terminal 52 and the power signal transmitted by the power supply terminal 51. Therefore, taking 220 volts as an example, if the voltage phase of the power line 53 used by the user...2 is also "AB phase", the count value is about i6 6p. If the voltage phase of the power line used by the user terminal W is "BC phase", then The result of the number of leaves of the counter is about 5. 5, and if the voltage phase rCA of the power line used by the user terminal 52 is only "," the word "before", the interval is set to "BC phase" in the coding module. "CA phase", set Ή=8·3χ as the threshold value for Τ2=13.8χ as the threshold value with 201100812 ””, that is, the count value is less than 8.3 X is greater than

Referring to Figure 3, the phase identification principle of 110 volts is the same as 22 volts. The difference is only the phase of 110 volts.

When the phase identification module 12 receives the reset signal, each internal temporary storage area will be reset to zero; when the gray code counter 121 receives the start signal, it will start to start counting according to the clock signal, when the count value reaches At 22^, indicating that the time of one cycle is completed, the counter is reset to zero. The gray code represents the meaning of the 8-bit count value', and only one bit changes every time the count is counted, thereby reducing the system noise. The output of the gray code counter 121 is transmitted to the latch 122. When the signal controller 12G receives the stop signal, it sends a latch signal, and after the latch 122 receives the shackle signal, it will receive the received signal. The count value is temporarily stored. The signal controller 120 is configured to make the first generated stop signal valid after each start signal is generated, and the signal controller 120 sends a shackle signal to the shackle 122 when receiving the stop signal determined to be valid. . In the coding module, the preferred embodiment uses two encoders, a first encoder 123 and a second encoder 124. The count value output by the latcher 122 is sent to the two encoders at the same time 201100812. To do the encoding, the outputs of the encoders 123, 124 are fed into a two-selected multiplexer 125.
