Problems solved by technology

[0003] Taking the above-mentioned patent as an example, although the smart meter and the external circuit breaker are disclosed, and the action (automatic closing) of the two under specific conditions is also involved, judging from the description and the drawings of the description, no further disclosure of the smart meter is made. How to achieve association and pairing with off-meter circuit breakers needs to be further improved

[0037] Preferably, the method for automatically associating and pairing the smart meter with the external circuit breaker includes the following steps:

[0038] Step S1: The smart meter and the off-meter circuit breaker are initialized respectively. The smart meter automatically scans peripheral devices based on an implicit custom protocol to obtain a device list. The off-meter circuit breaker is discovered by the smart meter;

[0039] Step S2: The smart meter and the external circuit breaker are linked to confirm the detection state;

[0040] Step S3: The smart meter and the external circuit breaker are linked to confirm the shutdown detection state;

[0041] Step S4: The smart meter continuously detects whether the power after the meter changes. If the number of confirmation times is reached, then confirm the target to establish a connection, otherwise repeat step S2 (designate the device address of another device in the device list of the smart meter);

[0042] Step S5: T...

Abstract

The invention discloses an intelligent electric meter and out-of-meter circuit breaker automatic association pairing method. The intelligent electric meter and out-of-meter circuit breaker automatic association pairing method comprises the following steps that an intelligent electric meter and an out-of-meter circuit breaker are initialized respectively, the intelligent electric meter is started to automatically scan peripheral Bluetooth devices through a Bluetooth module to obtain a device list, and meanwhile the out-of-meter circuit breaker enters into a wireless broadcast mode so that the out-of-meter circuit breaker is discovered by the intelligent electric meter; S2, the intelligent electric meter and the out-of-meter circuit breaker are linked to confirm a starting detection state; and S3, the intelligent electric meter and the out-of-meter circuit breaker are linked to confirm a closing detection state. By using the intelligent electric meter and out-of-meter circuit breaker automatic association pairing method of the invention, in a pairing process, two parties carry out identity authentication through a Bluetooth protocol or an implicit custom protocol, and simultaneously,a related encryption function is added into the protocol so that the protocol has relatively high security.

Description

technical field [0001] The invention belongs to the technical field of electric power ubiquitous internet of things, and in particular relates to a method for automatically associating and pairing a smart meter and an external circuit breaker. Background technique [0002] The publication number is CN204462252U, the subject name is smart meter control circuit, and its technical scheme discloses "the front-end voltage sampling unit is coupled with the incoming line end of the relay in the smart meter; the back-end voltage sampling unit is connected with the outgoing line end of the relay in the smart meter Coupling; the detection unit is used to lead the electrical signal of the front-end voltage sampling unit to the back-end voltage sampling unit when it is turned on; the relay control circuit is used to turn on or close the relay; the single-chip microcomputer, its first input terminal and the second The input terminals are respectively coupled to the output terminals of th...
