The target pipelines, namely named pipelines corresponding to target addresses, may correspond to the receiving ends one to one, and the target pipelines may be determined according to addresses of data to be sent. The dual-core smart meter 100 may transmit the data to be transmitted to a corresponding receiving end through the target pipeline via a virtual bus. In addition, the named pipes may not correspond to the receiving ends one to one, and for example, a plurality of named pipes may correspond to one receiving end.
According to the data distribution method based on the double-core intelligent ammeter, data to be sent by a sending end is received through a virtual bus, a target address of the data to be sent is determined according to the type of the data to be sent, a named pipeline corresponding to the target address is obtained and used as a target pipeline, the data to be sent is sent to a corresponding receiving end through the target pipeline through the virtual bus, the named pipeline can achieve communication between the receiving end and the virtual bus, and the named pipeline can correspond to the receiving end one to one.

The named pipe may be a pair of pipes and may include a read pipe and a write pipe, wherein the read pipe may be a pipe used by the two-core smart meter 100 to receive data from the pipe through the virtual bus 102, for example, data from a service in the two-core smart meter 100 may be received through the virtual bus 102, and data from an application associated with the two-core smart meter 100 may also be received; the write pipe may be a pipe through which the two-core smart meter 100 transmits data through the virtual bus 102, for example, the virtual bus 102 may be used to distribute data to a service in the two-core smart meter 100 through the write pipe, or may be transmitted to an application associated with the two-core smart meter 100. The application can be installed in the dual-core intelligent electric meter 100, and also can be installed in the external equipment of the dual-core intelligent electric meter, and the dual-core intelligent electric meter 100 is communicated with the external interface of the dual-core intelligent electric meter 100. The two-core intelligent electric meter 100 can establish a pair of named pipelines with the applications and the services through the virtual bus 102 respectively, the named pipelines can be in one-to-one-way communication, one end of each pipeline is only written, and the other end of each pipeline is only read; in addition, the same process pipe can only be opened once in a read-only and write-only manner. The virtual bus 102 may also create a snoop thread that may be used to snoop and receive data sent by the above-described applications and services onto the virtual bus 102.
Through the embodiment, the two-core smart electric meter 100 can create a named pipeline one-to-one with the application and service through the virtual bus 102 to receive or write data, and compared with a traditional mode that the whole meter needs to be replaced to send data of different types of interfaces, the scheme can adapt to the data distribution requirement of the two-core smart electric meter, and the effect of reducing the data distribution cost of the two-core smart electric meter is also achieved.
In an embodiment, before determining a target address of data to be sent according to a type of the data to be sent, the method further includes: judging whether a target address carried in data to be sent is complete or not; if the target address is complete, determining the type as the reply data; and if the target address is not complete, determining the type as the request data.
In this embodiment, the data to be sent may be data received through the virtual bus 102, and the data may be sent through a reading pipe in the named pipe by a service in the dual-core smart meter 100, or may be sent to the virtual bus 102 through a reading pipe in the named pipe by an application associated with the dual-core smart meter 100, where the application associated with the dual-core smart meter 100 may be an application inside the dual-core smart meter 100, or an application outside the dual-core smart meter 100, and the application outside the dual-core smart meter 100 may perform communication data transmission with the dual-core smart meter 100 through a corresponding interface of the dual-core smart meter 100. The destination address may be an address of a receiving end to which the data to be sent needs to be sent. The virtual bus 102 in the dual-core smart meter 100 may receive the data to be sent, and determine the type and address of the data to be sent by analyzing the distribution function. Specifically, the virtual bus 102 may perform target address integrity judgment after receiving the data to be sent, and if the target address is definite, that is, the target address is complete, the virtual bus 102 may determine that the type of the data to be sent is the reply data, and if the target address is indefinite, that is, the target address is incomplete, the virtual bus 102 may determine that the type of the data to be sent is the request data. In addition, when the virtual bus 102 determines that the data to be sent is the request data, the data can be distributed according to the data identifier of the request data, so as to obtain the explicit target address of the request data.
Through this embodiment, the two-core smart meter 100 can determine the type of the data to be sent according to the integrity of the target address of the data to be sent by using the virtual bus 102, so that the sending mode of the data to be sent can be determined quickly, and the data distribution efficiency of the two-core smart meter is improved.

In this embodiment, the reply data may be one of the data to be sent, and the reply data may be data that the receiving end of the request data responds to the request data. The dual-core smart meter 100 may determine the type of the data to be sent through the virtual bus 102, where the reply data carries a complete target address, that is, the first address, and specifically, the target address may be an address of a sending end of the request data corresponding to the reply data, that is, a source address of the reply data. The virtual bus 102 of the two-core smart meter 100 may perform data transmission with the sending end through a named pipe, that is, the virtual bus 102 in the two-core smart meter 100 may return the reply data to the sending end of the request data corresponding to the reply data through the named pipe corresponding to the sending end.
Through the embodiment, the virtual bus 102 in the dual-core smart electric meter 100 can return the reply data to the sending end corresponding to the carried target address in a manner of naming a pipeline when the data to be sent is judged to be the reply data, and compared with a conventional manner that the whole meter needs to be replaced to send data of different interfaces, the scheme can adapt to the data distribution requirement of the dual-core smart electric meter, and the effect of reducing the data distribution cost of the dual-core smart electric meter is also achieved.
In one embodiment, as shown in FIG. 3, FIG. 3 is a timing diagram of the data distribution step in one embodiment. After the second address carried by the request data is taken as the target address, the method further comprises the following steps: determining the address of a receiving end corresponding to the request data according to the data identification carried in the request data; when the determination is successful, taking the determined address of the receiving end as a second address; when the determination fails, determining the address of a receiving terminal corresponding to the request data according to the control code and the plurality of data identifiers carried in the request data, and taking the determined address of the receiving terminal as a second address; and sending the request data to a receiving end corresponding to the second address through a named pipeline corresponding to the receiving end.

The data identifier may be an identifier carried in the request data, and may be used to determine a second address, i.e., a target address, of the request data. Specifically, the two-core smart meter 100 may determine, through a data identifier carried in the request data, for example, the data identifier DI3, an address of a receiving end corresponding to the request data, that is, may perform primary data distribution on the request data, and when a destination address may be determined according to the data identifier DI3, the virtual bus 102 may send the request data to the corresponding receiving end through a named pipe corresponding to the destination address. When the virtual bus 102 in the two-core smart meter 100 cannot determine the destination address according to the data identifier DI3, the virtual bus 102 may also determine the address of the receiving end of the request data as the second address, i.e., the destination address, according to the control code of the request data and the data identifiers. Specifically, when the virtual bus 102 cannot determine the destination address according to the primary data distribution, the destination address of the request data may be determined according to 645 frame control codes and a combination of multiple data identifiers, for example, a combination of DI0 and DI 3.
