Wireless transmission anti-missort tester and working method thereof

Abstract

Belonging to the field of electric power technology, the invention specifically relates to a wireless transmission anti-missort tester and a working method thereof. The wireless transmission anti-missort tester includes a transmission device and a receiver, the transmission device is equipped with a power supply module, an ultra narrow band frequency selection module, a transmission channel and aground wire terminal. The ultra narrow band frequency selection module and the transmission channel are in parallel connection, the ground wire terminal is connected to the ultra narrow band frequencyselection module, and the output end of the ultra narrow band frequency selection module is connected to the input end of an amplification circuit. The tester provided by the invention can carry outdetection positioning without enter a household, and omits tedious access procedure. The tester has the advantages that: the time for correction detection of a user meter is short, the work efficiencyis improved, unified inspection is carried out on a plurality of electric meters in one meter box, and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a wireless transmission anti-collude tester and a working method thereof. Background technique [0002] Most of the complaints received by the power company that the household meter does not correspond occur within 1-2 years after the handover of the new house. Using traditional methods to determine whether the connection is wrong and to locate the wrong specific user will take a lot of work. Testing in the same metering box requires most users to be at home. If the error occurs to a user who has not checked in, there is no way to solve it in the short term, and it often takes months to correct the error. [0003] In recent years, the application of ultra-low frequency communication has become more and more extensive. At present, the signal is loaded on the socket in the user's room through the carrier module, and the signal is received and demodulated at the ...

Problems solved by technology

[0003] In recent years, the application of ultra-low frequency communication has become more and more extensive. At present, the signal is loaded on the socket in the user's room through the carrier module, and the signal is received at the metering box for demodulation. It is required to enter the user's room to realize the loading of the signal. At present, in residential areas where the occupancy rate is not very high, it is necessary to enter the household for the investigation of the non-corresponding phenomenon of the conventional low-voltage household meter relationship, which brings great inconvenience to the investigation work.
