Description

Technical field:

[0001] The present invention belongs to the technical field of novel configuration of intelligent circuit breaker communication, and in particular relates to a novel system and method for configuring a communication address of an intelligent circuit breaker. Background technology:

[0002] Miniature circuit breakers (MCBs) are the most commonly used electrical distribution terminal protection devices for building terminals such as residential life and industrial applications. Traditional miniature circuit breakers include 1P, 2P, 3P, 4P, etc., which are used for short circuit, overload, overvoltage and other power protection of single-phase and three-phase electricity. Traditional miniature circuit breakers are mainly composed of various operating mechanisms (handles, plastic parts, springs, etc.), double gold contacts (double gold sheets, dynamic and static contacts, etc.), tripping protection devices (electromagnetic trippers, etc.), arc extinguishing devices (arc extinguishing grids, etc.) and other mechanical structures. The structure is simple and practical, but the operation is cumbersome. Intelligent miniature circuit breakers (IMCBs) are based on the mechanical structure of traditional miniature circuit breakers, adding intelligent control and detection parts to realize real-time monitoring and remote control of traditional circuit breakers, simplifying people's cumbersome manual operation of traditional circuit breakers, facilitating people's detection and understanding of household electricity consumption, and controlling physical energy such as current.

[0003] In the existing management of communication of newly configured intelligent circuit breakers, the intelligent miniature circuit breaker, as a working unit, is independent of the entire system and cannot be managed in a timely and effective manner. It is also impossible to obtain the current working status of the miniature circuit breaker in real time. At the same time, it is impossible to uniformly control multiple intelligent miniature circuit breakers in an integrated system, nor is it possible for multiple miniature circuit breakers to uniformly and collaboratively perform a series of operations. It is also impossible to automatically and effectively update and iterate the functions of the intelligent miniature circuit breakers, and it is impossible to accurately understand the power consumption of each circuit breaker. Summary of the invention:

[0004] The present invention provides a new system and method for configuring the communication address of an intelligent circuit breaker, which aims to solve the problem that in the existing management of the communication of the newly configured intelligent circuit breaker, the intelligent miniature circuit breaker, as a working unit, is independent of the entire system and cannot be managed in a timely and effective manner, nor can the current working status of the miniature circuit breaker be obtained in real time. At the same time, it is impossible to uniformly control multiple intelligent miniature circuit breakers in an integrated system, nor can multiple miniature circuit breakers uniformly and collaboratively perform a series of operations, and the intelligent miniature circuit breaker cannot be automatically and effectively updated and iterated in terms of function, and the power consumption of each circuit breaker cannot be accurately obtained.

[0005] The embodiment of the present invention provides a novel system for configuring a communication address of an intelligent circuit breaker, comprising a novel micro-breaker power supply unit, a novel micro-breaker gateway interconnection communication unit GW and one or more novel intelligent micro-circuit breakers MCB;

[0006] The novel micro-break power supply unit is electrically connected to the novel micro-break gateway interconnection communication unit GW and the novel intelligent circuit breaker respectively;

[0007] The novel micro-breaker gateway interconnection communication unit GW is communicatively connected with the novel intelligent micro-circuit breaker MCB;

[0008] The novel micro-break power supply unit is used to stably provide rated voltage and current to the novel micro-break gateway interconnection communication unit GW and the novel intelligent miniature circuit breaker MCB;

[0009] The new micro-break gateway interconnection communication unit GW is used to uniformly manage all the new intelligent miniature circuit breakers MCB under its jurisdiction, that is, it can completely and effectively assign addresses to each micro-breaker in an orderly and non-repetitive manner, and can effectively access each new intelligent miniature circuit breaker MCB according to the address; the jurisdiction is the scope of the new intelligent miniature circuit breakers MCB that have a communication connection relationship with the new micro-break gateway interconnection communication unit GW;

[0010] The novel intelligent miniature circuit breaker MCB is used to identify and receive broadcast commands, reply to single-point commands and self-regulate the address allocation pin level output;

[0011] The new micro-break gateway interconnection communication unit GW is also used to automatically send and receive commands, identify specific micro-break return information, and store micro-break information and its own information. The new micro-break gateway interconnection communication unit GW can create a command to allocate an address, and record the allocation command that has been sent and the confirmation information of the allocation address that has been received from the micro-break.

[0012] Furthermore, the communication between the novel micro-breaker gateway interconnection communication unit GW and the novel intelligent micro-circuit breaker MCB is performed through a BUS bus for command interaction;

[0013] The BUS is a collection of serial port sending data and serial port receiving data of the new intelligent miniature circuit breaker MCB. The BUS is used for command reception and reply between the new intelligent miniature circuit breaker MCB and the new miniature circuit breaker gateway interconnection communication unit GW, namely, addr signal in and addr signal out;

[0014] The addr signal in is the address allocation configuration pin of the new intelligent miniature circuit breaker MCB. This is a single signal channel that can only receive but not send signals.

[0015] The addr signal out is the address allocation configuration pin of the new intelligent miniature circuit breaker MCB. This is a single signal channel that can only send but not receive signals.

[0016] A new method for configuring the communication address of an intelligent circuit breaker, the communication steps are as follows:

[0017] S1: The power supply supplies power to all devices, connects the new intelligent miniature circuit breaker MCB and the new miniature circuit breaker gateway interconnection communication unit GW, ensures that the BUS communication between the new intelligent miniature circuit breaker MCB and the new miniature circuit breaker gateway interconnection communication unit GW is unobstructed, and the new miniature circuit breaker gateway interconnection communication unit GW starts the entire address allocation process, sends a broadcast frame command, and notifies all new intelligent miniature circuit breakers MCB to lower their address allocation pins, so that the next level new intelligent miniature circuit breaker MCB of the new intelligent miniature circuit breaker MCB enters the state of accepting the allocated address;

[0018] S2: The new micro-breaker gateway interconnection communication unit GW sends a new intelligent micro-circuit breaker MCB self-check command. The new intelligent micro-circuit breaker MCB self-check command is used for the micro-breaker to determine whether it is in the address allocation state. If so, no operation is required. Otherwise, the micro-breaker sets its state to the address allocation state.

[0019] S3: The new micro-breaker gateway interconnection communication unit GW broadcasts a command to make the new intelligent micro-circuit breaker MCB pull up its own address allocation pin; because the new intelligent micro-circuit breaker MCB must receive the address and pull down or pull up the level to enter or exit the state of accepting the allocated address, at this time only one new intelligent micro-circuit breaker MCB cannot exit the state of allocating the address, so this new intelligent micro-circuit breaker MCB will receive the write address command subsequently sent by the gateway, thus fixing the new intelligent micro-circuit breaker MCB1 with the address "1";

[0020] S4: The new micro-breaker gateway interconnection communication unit GW starts with the new intelligent miniature circuit breaker MCB No. 1 to determine the new intelligent miniature circuit breakers MCB2 and MCB3 at addresses No. 2 and 3.

[0021] Furthermore, the new micro-breaker gateway interconnection communication unit GW, the new intelligent miniature circuit breaker MCB1, the new intelligent miniature circuit breaker MCB2 and the BUS bus of the new intelligent miniature circuit breaker MCB3 are connected;

[0022] The addr signal out terminal of the new intelligent miniature circuit breaker MCB1 is connected to the addr signal out terminal of the new intelligent miniature circuit breaker MCB2, and the addr signal out terminal of the new intelligent miniature circuit breaker MCB2 is connected to the addr signal out terminal of the new intelligent miniature circuit breaker MCB3.

[0023] Furthermore, the steps of connecting the new micro-breaker gateway interconnection communication unit GW, the new intelligent miniature circuit breaker MCB1, the new intelligent miniature circuit breaker MCB2 and the new intelligent miniature circuit breaker MCB3 are as follows:

[0024] S1-1: The new micro-circuit breaker gateway interconnection communication unit GW broadcasts a command to clear the address of the new intelligent miniature circuit breaker MCB via the BUS bus;

[0025] S1-2: The new micro-breaker gateway interconnection communication unit GW broadcasts a command to pull down the addr signal out terminal of the new intelligent miniature circuit breaker MCB via the BUS bus; at this time, since the addr signal out terminals of the new intelligent miniature circuit breakers MCB1 and MCB3 are pulled down, the addr signal in terminals of the new intelligent miniature circuit breakers MCB2 and MCB3 receive low-level signals, and the new intelligent miniature circuit breakers MCB2 and MCB3 are in the address allocation state;

[0026] S1-3: The new micro-circuit breaker gateway interconnection communication unit GW broadcasts a detection command via the BUS bus; after receiving the command, the new intelligent micro-circuit breaker MCB1 sets its state to the address allocation state; the new intelligent micro-circuit breakers MCB2 and MCB3 are already in the address allocation state at this time, so no changes are required. After this command is issued, all new intelligent micro-circuit breakers MCB enter the address allocation state;

[0027] S1-4: The new micro-break gateway interconnection communication unit GW broadcasts a command to pull up the addr signal out terminal of the new intelligent miniature circuit breaker MCB via the BUS bus; at this time, since the addr signal out terminals of the new intelligent miniature circuit breakers MCB1 and MCB3 are pulled high, the addr signal in terminals of the new intelligent miniature circuit breakers MCB2 and MCB3 receive high-level signals, and the new intelligent miniature circuit breakers MCB2 and MCB3 end the address allocation state; the addr signal in terminal of the new intelligent miniature circuit breaker MCB1 does not receive a high level, so it is still in the address allocation state;

[0028] S1-5: The new micro-breaker gateway interconnection communication unit GW broadcasts a command to write the address "1" to the new intelligent micro-circuit breaker MCB via the BUS bus; at this time, only the new intelligent micro-circuit breaker MCB1 is in the address allocation state, so only the new intelligent micro-circuit breaker MCB1 can execute the broadcast command, and the communication address of the new intelligent micro-circuit breaker MCB1 is "1";

[0029] S1-6: The new micro-breaker gateway interconnection communication unit GW sends a command to the new intelligent miniature circuit breaker MCB with the designated communication address "1" via the BUS bus to pull down the addr signal out terminal; the new intelligent miniature circuit breaker MCB1 receives the command and executes to pull down its own addr signal out terminal, then the addr signal in terminal of the new intelligent miniature circuit breaker MCB2 receives a low-level signal, so that the new intelligent miniature circuit breaker MCB2 is in the address allocation state;

[0030] S1-7: The new micro-breaker gateway interconnection communication unit GW broadcasts a command to write the address "2" to the new intelligent micro-circuit breaker MCB via the BUS bus; at this time, only the new intelligent micro-circuit breaker MCB2 is in the address allocation state, so only the new intelligent micro-circuit breaker MCB2 can execute the broadcast command, and the communication address of the new intelligent micro-circuit breaker MCB2 is "2";

[0031] S1-8: The new micro-break gateway interconnection communication unit GW sends a command to the new intelligent miniature circuit breaker MCB with the designated communication address "2" via the BUS bus to pull down the addr signal out terminal; the new intelligent miniature circuit breaker MCB2 receives the command and executes to pull down its own addr signal out terminal, then the addr signal in terminal of the new intelligent miniature circuit breaker MCB3 receives a low-level signal, so that the new intelligent miniature circuit breaker MCB3 is in the address allocation state;

[0032] S1-9: The new micro-breaker gateway interconnection communication unit GW broadcasts a command to write the address "3" to the new intelligent micro-circuit breaker MCB via the BUS bus; at this time, only the new intelligent micro-circuit breaker MCB3 is in the address allocation state, so only the new intelligent micro-circuit breaker MCB3 can execute the broadcast command, and the communication address of the new intelligent micro-circuit breaker MCB3 is "3";

[0033] S1-10: The new micro-break gateway interconnection communication unit GW sends a command to the new intelligent miniature circuit breaker MCB with the designated communication address "3" to pull down the addr signal out terminal through the BUS bus; the new intelligent miniature circuit breaker MCB3 receives the command and executes to pull down its own addr signal out terminal, but at this time there is no new intelligent miniature circuit breaker MCB responding to the signal sent from the addr signal out terminal, and this frame of data will return failure information to the new micro-break gateway interconnection communication unit GW through the BUS bus;

[0034] S1-11: The new micro-break gateway interconnection communication unit GW receives the reply frame of the command to lower the addr signal out end sent by the new intelligent micro-circuit breaker MCB at a single point on the BUS bus. After confirming that it is a failure, the address allocation is ended and the entire address allocation process is ended.

[0035] The beneficial effects of the present invention are:

[0036] The present invention utilizes the characteristics of the receiving signal of the micro-break address allocation status to quickly obtain the only special micro-break among all the micro-breaks under the gateway as micro-break No. 1, and allocates the remaining addresses starting with it. At the same time, all the micro-breaks are effectively and orderly assembled into a whole, which is uniformly regulated by the gateway. It also effectively solves the problems of being unable to accurately obtain the data information of each micro-break, being unable to obtain the current working status of the miniature circuit breaker in real time, being unable to perform a series of operations in a unified and coordinated manner on multiple miniature circuit breakers, being unable to automatically and effectively update and iterate the functions of the intelligent miniature circuit breaker, and being unable to accurately obtain the power consumption of each circuit breaker.

A system for configuring a communication address of an intelligent circuit breaker according to claim 3, characterized in that: The steps of connecting the miniature circuit breaker gateway interconnection communication unit GW, the intelligent miniature circuit breaker MCB1, the intelligent miniature circuit breaker MCB2 and the intelligent miniature circuit breaker MCB3 are as follows: S1-1: The micro-circuit breaker gateway interconnection communication unit GW broadcasts a command to clear the address of the intelligent micro circuit breaker MCB via the BUS bus; S1-2: The micro-break gateway interconnection communication unit GW broadcasts a command to pull down the addr signal out terminal of the intelligent miniature circuit breaker MCB via the BUS bus; at this time, since the addr signal out terminals of the intelligent miniature circuit breakers MCB1 and MCB3 are pulled down, the addr signal in terminals of the intelligent miniature circuit breakers MCB2 and MCB3 receive low-level signals, and the intelligent miniature circuit breakers MCB2 and MCB3 are in the address allocation state; S1-3: The micro-breaker gateway interconnection communication unit GW broadcasts a detection command via the BUS bus; after receiving the command, the intelligent micro-circuit breaker MCB1 sets its state to the address allocation state; the intelligent micro-circuit breakers MCB2 and MCB3 are already in the address allocation state at this time, so no change is required. After this command is issued, all intelligent micro-circuit breakers MCB enter the address allocation state; S1-4: The micro-break gateway interconnection communication unit GW broadcasts a command to pull up the addr signal out terminal of the intelligent miniature circuit breaker MCB via the BUS bus; at this time, since the addr signal out terminals of the intelligent miniature circuit breakers MCB1 and MCB3 are pulled high, the addr signal in terminals of the intelligent miniature circuit breakers MCB2 and MCB3 receive high-level signals, and the address allocation state of the intelligent miniature circuit breakers MCB2 and MCB3 ends; the addr signal in terminal of the intelligent miniature circuit breaker MCB1 does not receive a high level, so it is still in the address allocation state; S1-5: The micro-break gateway interconnection communication unit GW broadcasts a command to write the address "1" to the intelligent micro-circuit breaker MCB via the BUS bus; at this time, only the intelligent micro-circuit breaker MCB1 is in the address allocation state, so only the intelligent micro-circuit breaker MCB1 can execute the broadcast command, and the communication address of the intelligent micro-circuit breaker MCB1 is "1"; S1-6: The micro-break gateway interconnection communication unit GW sends a command to the intelligent miniature circuit breaker MCB with the designated communication address "1" to pull down the addr signal out terminal via the BUS bus; the intelligent miniature circuit breaker MCB1 receives the command and executes to pull down its own addr signal out terminal, then the addr signal in terminal of the intelligent miniature circuit breaker MCB2 receives a low-level signal, so that the intelligent miniature circuit breaker MCB2 is in the address allocation state; S1-7: The micro-break gateway interconnection communication unit GW broadcasts a command to write the address "2" to the intelligent miniature circuit breaker MCB via the BUS bus; at this time, only the intelligent miniature circuit breaker MCB2 is in the address allocation state, so only the intelligent miniature circuit breaker MCB2 can execute the broadcast command, and the communication address of the intelligent miniature circuit breaker MCB2 is "2"; S1-8: The micro-break gateway interconnection communication unit GW sends a command to the intelligent miniature circuit breaker MCB with the designated communication address "2" to pull down the addr signal out terminal via the BUS bus; the intelligent miniature circuit breaker MCB2 receives the command and executes to pull down its own addr signal out terminal, then the addr signal in terminal of the intelligent miniature circuit breaker MCB3 receives a low-level signal, so that the intelligent miniature circuit breaker MCB3 is in the address allocation state; S1-9: The micro-breaker gateway interconnection communication unit GW broadcasts a command to write the address "3" to the intelligent micro-circuit breaker MCB via the BUS bus; at this time, only the intelligent micro-circuit breaker MCB3 is in the address allocation state, so only the intelligent micro-circuit breaker MCB3 can execute the broadcast command, and the communication address of the intelligent micro-circuit breaker MCB3 is "3"; S1-10: The micro-break gateway interconnection communication unit GW sends a command to the intelligent miniature circuit breaker MCB with the designated communication address "3" to pull down the addr signal out terminal through the BUS bus; the intelligent miniature circuit breaker MCB3 receives the command and executes to pull down its own addr signal out terminal, but at this time no intelligent miniature circuit breaker MCB responds to the signal sent from the addr signal out terminal, and this frame of data will return failure information to the micro-break gateway interconnection communication unit GW through the BUS bus; S1-11: The micro-break gateway interconnection communication unit GW receives the reply frame of the command to lower the addr signal out terminal of the intelligent micro-circuit breaker MCB sent by a single point on the BUS bus, and after confirming that it is a failure, the address allocation is ended, and the entire address allocation process is ended.
