Embodiment 1

[0038] see figure 1 , figure 1 It is a schematic diagram of the composition of the detection host in the present invention. The invention proposes a variable load detection method in electric meter paging detection, which includes a detection host and a detection slave, wherein the detection host includes: a host MCU, a plurality of photoelectric metering pulse reading devices, a host display, a host keyboard, and a host uplink communication module.

[0039] The host MCU also includes a storage system for data processing, storage and software operation.

[0040] Among them, there are multiple photoelectric metering pulse reading devices, generally 4 to 8 are selected, which can read the light output metering pulse of the meter respectively, and then convert it into an electrical signal, and then the host MCU reads the change of the pulse frequency and automatically eliminates the user side The part that does not conform to the programming law changes, and then compares whet...

Abstract

The invention discloses a variable load detection method in electricity meter channeling detection. The method comprises the following steps of: step 1, downloading a detection task by virtue of a detection host, and checking whether user electricity meter numbers needing to be detected are consistent with task requirements; step 2, mounting a photoelectric metering pulse reading device of the detection host on a user electricity meter with channeling suspicion; step 3, connecting the detection slave to a socket on the user side, allowing the detection slave to start working, and changing the load of the socket according to programmable load equipment; and step 4, detecting photoelectric metering pulse generated by different electricity meters by the detection host, and comparing the detection result of the detection host and load change of variable load equipment on the user side. Therefore, the technical effects of improving the electricity meter channeling detection efficiency and electricity meter channeling judgment accuracy and alleviating the labor intensity are achieved.

Description

technical field [0001] The invention relates to the field of electric equipment information research, in particular to a variable load detection method in the electric meter series detection. Background technique [0002] With the increase of new residential buildings, there are more and more problems with electricity consumption, among which the problem of stringing households with electric meters also occurs frequently. Existing serial households to ammeter all are by pulling the brakes, judge according to the on and off of lighting lamps. In some places, power failure detection equipment is used for detection, but the equipment on the meter side and the user side need to be equipped with communication modules to achieve data interaction on both sides. The above detection methods all need to be powered off to detect, which seriously affects the daily life of users. The technology is backward, the equipment cost is high and the efficiency is low. [0003] To sum up, in th...
