A circuit breaker is generally provided in an intelligent distribution box, and the circuit breaker is a switching device capable of carrying and breaking a current under normal loop conditions and carrying and breaking a current under abnormal loop conditions within a prescribed time. The circuit breaker is divided into a high-voltage circuit breaker and a low-voltage circuit breaker according to the application range, and the division of a high-voltage boundary line and a low-voltage boundary line is fuzzy, and is generally called as a high-voltage electrical appliance with the voltage of more than 3 kV. A main circuit breaker refers to a circuit breaker that is used for switching a main circuit, such as a distribution box. Shunt circuit breakers refer to circuit breakers that are used to make and break a single circuit, such as one shunt circuit in a distribution box. The intelligent circuit breaker is based on the traditional circuit breaker, and intelligent modules are added on hardware to further realize intelligent control functions, such as remote control switch, tripping automatic power transmission, electric leakage protection automatic detection, overvoltage protection, overload overcurrent protection and the like. The intelligent block terminal scheme of mainstream at present is on the basis of traditional circuit breaker, increases intelligent module to realize the function of intelligence. The intelligent modules are added to the circuit breakers, and the first scheme is that each circuit breaker is added with one intelligent module, so that the circuit breakers can be independently connected with the cloud server in a networking mode, but the scheme has higher hardware cost because each circuit breaker is added with one intelligent module; the second scheme is to extract the communication part function of the circuit breaker and make the circuit breaker into a communication module independently, so that the whole distribution box only needs to be provided with one communication module, the hardware cost is saved, but after the circuit breaker communication module is extracted, all the circuit breakers are identical in all aspects of appearance, hardware, software and the like, and the circuit breakers are difficult to distinguish.

Examples of the embodiments are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements throughout or elements having like or similar functionality. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
The following specifically describes the working principle of the address allocation method and the device of the intelligent distribution box shunt circuit breaker.
As shown in fig. 1, the method comprises the following steps:
s1, distributing shunt address information of a breaker;
the step S1 specifically includes: s1.1, distributing hash algorithm configuration frames to all branches of a circuit breaker; s1.2, sending a query frame comprising hash table rounds and hash table serial numbers to a shunt address of the circuit breaker; s1.3, receiving and responding to the query frame sent in the S1.2 by the shunt address of the circuit breaker, and returning a response frame to the query module; s1.4, distributing the response frame returned in the S1.3 to the idle address of the communication address table; s1.5, sending an address configuration frame containing address information and a configuration command to the shunt address of the breaker; s1.6, if the query module receives a plurality of response frames, indicating that hash table serial numbers in the query frames correspond to a plurality of circuit breaker shunt addresses and hash conflicts exist; step S1.6 starts address allocation of the next round under the condition that hash conflict exists, and step S1.6 completes address allocation when the number of shunt addresses of the allocated circuit breaker is the same as the preset number under the condition that hash conflict does not exist; s1.7, after the distribution of the shunt address of the circuit breaker is completed, storing the address and the characteristic information thereof into a communication address table so as to dynamically manage the shunt of the circuit breaker through the communication address table; the hash result has the possibility of collision, namely different input information obtains the same hash value; to reduce the collision probability, collisions can be gradually eliminated by multiple hashes and multiple communications; the uncertain information is reduced after each hash and communication confirmation, and the next hash table can be reduced (for example, the hash table is reduced by 1/2); the probability of collision of the hashes for a plurality of times is negligible by selecting proper hashes and table sizes, and the method has engineering feasibility. The circuit breaker shunt adopts circuit breaker shunt position information, address allocation time and random numbers respectively according to a control module command, and three hash values are calculated and stored, namely hs1, hs2 and hs3 respectively. The control module sends the query frame of hs1 and sends the broadcast frame of hash table serial number X (for example, 0-4095) in turn; when a query frame with the hash table serial number X is received, if the hash table serial number of a certain breaker shunt sx is X, a response frame is sent to the control module, and characteristic information such as breaker shunt position information is attached. And the control module recognizes that the sx breaker shunt exists after receiving the effective response frame, and allocates a breaker shunt address for the sx breaker shunt. If a plurality of valid response frames are received or non-response frame information is detected (for example, circuit breaker shunt reply data is available but not response frames), judging that the hash serial number corresponds to a plurality of circuit breaker shunts, and recording the conflict and continuing to send a query frame; after the control module sequentially sends all inquiry frames of hs1, if the number of the effective circuit breaker branches is identified to be equal to the number N of the configuration circuit breakers branches and hash collision is not detected, ending address allocation; if a hash collision is detected, an hs2 query is entered. The hs2 query is similar to the hs1 query process, and incremental address allocation is adopted at this time, namely only the circuit breaker with unassigned address is in shunt participation; the circuit breaker shunt with the address distribution queried by hs1 does not respond; when hs2 is finished, if hash collision still exists, entering into hs3 for inquiring; the hs3 query is similar to the hs2 procedure described above.
S2, acquiring an address allocation instruction; the step S2 specifically includes: s2.1, outputting an address allocation instruction to a control module by a user; s2.2, the control module transmits the address allocation instruction output in the S2.1 to the query module;
s3, obtaining distributable shunt state information; the step S3 specifically includes: s3.1, the query module receives an address allocation instruction input by the control module; s3.2, acquiring time information according to the time module, and generating a random number according to the time information; s3.3, converting the address allocation instruction and the time information into a hash algorithm configuration frame; s3.4, carrying out hash calculation according to the configuration frame obtained in the S3.3 so as to generate a hash table sequence number; s3.5, the circuit breaker branches to obtain the configuration frame in S3.3, and the hash table sequence number in the configuration frame is compared with the hash table sequence number generated by the circuit breaker; the step S3.5 specifically includes that if the serial number of the configuration frame hash table is the same as the serial number of the hash table of the circuit breaker shunt, a response frame is returned when the circuit breaker shunt is in an idle state, and the inquiry module returns the state information of the circuit breaker shunt to the control module; the step S3.5 further comprises the step that when the circuit breaker shunt is in an occupied state, the query module repeats the step S3.2; s3.6, when the number of the circuit breaker branches obtained in the S3.5 is the same as the preset number, all the circuit breaker branches are in an occupied state, and the query module returns unavailable connection information to the control module;
s4, address allocation is carried out on the shunt of the circuit breaker.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
