Example 1
The embodiment provides a communication method of an intelligent electric energy meter, which may be executed by a master device including a controller, a memory and a bluetooth module, where the master device may be an intelligent electric energy meter, and may be a bluetooth meter reader, a bluetooth palm device, and the like, and the connection between the intelligent electric energy meter and a plurality of master and slave devices is realized through scanning, judgment and connection of the master device, so as to realize communication of the intelligent electric energy meter, as shown in fig. 1, the communication method includes the following steps:
step S101, scanning broadcast information of slave equipment, wherein the broadcast information carries a unique identifier of the slave equipment.
Under the condition that the master device is the intelligent electric energy meter, the slave device can be a Bluetooth lockset, a Bluetooth circuit breaker, a Bluetooth pulse converter and the like, and under the condition that the master device is not the intelligent electric energy meter, the slave device can also be the intelligent electric energy meter. Under the condition that the master device is the intelligent electric energy meter, the slave device needs to receive a control command issued by a Bluetooth module of the intelligent electric energy meter. Under the condition that the main device is not the intelligent electric energy meter, the main device such as a Bluetooth palm machine and a Bluetooth meter reader needs to acquire meter data of the intelligent electric energy meter through a Bluetooth module of the intelligent electric energy meter.
The slave device broadcasts the unique identifier of the slave device through the Bluetooth equipped by the slave device, and meanwhile, the master device scans the broadcast information of the slave device through the Bluetooth equipped by the master device and identifies the unique identifier carried in the broadcast information through the controller. The unique identifier may be an address identifier, and is transmitted in a data link layer in the form of a data frame, and the master device may determine the designated slave device to be connected according to the scanned unique identifier.
Step S102, judging whether an identifier consistent with the unique identifier exists in an identifier set written in the main equipment in advance;
if so, establishing connection with the slave equipment;
if not, the scanning is continued or the scanned unique identifier is written into the identifier set on the master device again. The intelligent electric energy meter is the master device or the slave device.
After scanning the unique identifier broadcast by the slave device, the master device searches whether an identifier consistent with the unique identifier exists in an identifier set written in the master device in advance, wherein the identifier set can be stored in a memory connected with the master device, and a controller connected with the master device is used for searching the identifier set in the memory. If the identifier consistent with the unique identifier exists in the identifier set, determining that the slave device is the slave device to be connected, and establishing communication connection with the slave device. Further, the master device may simultaneously scan a plurality of unique identifiers, and each slave device corresponds to its own unique identifier, that is, the master device may simultaneously scan a plurality of slave devices and establish a communication connection with the plurality of slave devices.
For example, as shown in fig. 2, when the intelligent power meter is the master device, a set of identifiers, such as { a00000000001, C00000000001, C00000000002, D00000000001}, is written into the memory of the intelligent power meter. The external slave device a, the external slave device B, the external slave device C and other devices broadcast their own unique identifiers, such as the external slave device a broadcasting their own unique identifier C00000000001, the external slave device B broadcasting their own unique identifier C00000000002 and the external slave device C broadcasting their own unique identifier C00000000003, by using their own embedded bluetooth module a, embedded bluetooth module B and embedded bluetooth module C. The Bluetooth module of the intelligent electric energy meter scans broadcast information, and according to the scanned unique identifications C00000000001, C00000000002 and C00000000003, the identifications consistent with C00000000001 and C00000000002 exist in the identification set, and at the moment, the Bluetooth module of the intelligent electric energy meter establishes communication connection with the external slave device A and the external slave device B. Further, since the external slave C does not establish a connection with the master device, the unique identifier of the external slave C may be written into the identifier set, and the master device continues to scan to establish a connection with the external slave C.
As shown in fig. 2, when the intelligent electric energy meter is a slave device, the external master device at this time may be a bluetooth meter reader, a bluetooth palm machine, or the like. After the intelligent electric energy meter is powered on, the controller configures the unique identifier for the Bluetooth module of the intelligent electric energy meter and broadcasts the unique identifier through the Bluetooth module of the intelligent electric energy meter. After the external main device 1, the external main device 2 itself embedded bluetooth module 1, and the embedded bluetooth module 2 scans the unique identifier broadcasted by the bluetooth module of the intelligent electric energy meter, it is determined whether an identifier consistent with the unique identifier broadcasted by the bluetooth module of the intelligent electric energy meter exists in the identifier set written in the external main device 1 and the external main device 2 in advance, if so, connection with the bluetooth module of the intelligent electric energy meter is established, if not, scanning is continued, or the unique identifier of the bluetooth module of the intelligent electric energy meter is written in the identifier set of the external main device 1 or the external main device 2, so as to establish communication connection. Further, when the intelligent electric energy meter is a slave device, according to the communication method provided in this embodiment, the bluetooth module of the intelligent electric energy meter can establish communication connection with a plurality of external master and slave devices at the same time.
Further, in this embodiment, the external slave devices to be connected with the master device may be screened from a plurality of bluetooth broadcast messages according to an identifier type of the unique identifier broadcast by the external slave devices, where the identifier type may be an MAC address type, and then it is determined whether an identifier consistent with the unique identifier exists in the identifier set from the screened external slave devices to be connected with the master device.
In this embodiment, the intelligent electric energy meter may be used as both a master device and a slave device, and when the intelligent electric energy meter is used as the master device, communication connection may be established with a plurality of designated external slave devices according to the unique identifier; when the intelligent electric energy meter is used as the slave device, communication connection can be simultaneously established with a plurality of external master devices according to the unique identification broadcasted by the intelligent electric energy meter. Therefore, the communication method for the intelligent electric energy meter provided in this embodiment can enable the intelligent electric energy meter to be quickly connected with the designated external master and slave devices and to perform communication interaction with the corresponding external master and slave devices simultaneously in the use process.
As an optional implementation manner, in an embodiment of the present invention, the method for communicating an intelligent electric energy meter further includes:
checking whether a disconnected slave device exists at preset time intervals, and receiving target broadcast information, wherein the target broadcast information and the broadcast information of the slave device adopt the same protocol;
when the disconnected slave equipment exists, judging whether the target unique identifier in the target broadcast information exists in the identifier set or not;
when the target unique identification is not present in the identification set, replacing the unique identification of the disconnected slave device in the identification set with the target unique identification.
As described above, in the case that the master device is the intelligent electric energy meter, the external slave device may be a bluetooth lock, a bluetooth circuit breaker, a bluetooth pulse converter, or the like, and the external slave device needs to receive a control command issued by a bluetooth module of the intelligent electric energy meter. Taking an external slave device bluetooth breaker as an example, the bluetooth breaker is a key device for realizing a remote fee control function in cooperation with an intelligent electric energy meter, and generally maintains a continuous connection state with a bluetooth module of the intelligent electric energy meter. Similarly, bluetooth tool to lock, bluetooth pulse converter also generally keep the continuous connection state with the bluetooth module of intelligent ammeter. If the external slave equipment is replaced in the normal working process of the intelligent electric energy meter and the external slave equipment, the connection with the intelligent electric energy meter is not established in time, and the problems that partial functions cannot be realized and the like occur.
In this embodiment, every preset time, the smart electric energy meter main controller checks whether an external slave device that has been disconnected exists, may check in an answering manner, receive target broadcast information, and scan whether an external slave device that waits for connection exists, where the target broadcast information and the broadcast information of the external slave device use the same protocol. When detecting that the disconnected external slave equipment exists, further judging whether the target unique identifier in the target broadcast information exists in the identifier set of the intelligent electric energy meter; in case it is not present in the identification set, the unique identification of the disconnected slave device in the identification set may be replaced by the target unique identification.
For example, the intelligent electric energy meter establishes communication connection with the external slave device a, the external slave device B and the external slave device C, the intelligent electric energy meter checks at preset time intervals, when it is checked that the disconnected external slave device C exists, and target broadcast information is received, and the target unique identifier (C00000000004) in the target broadcast information and the unique identifier of the external slave device adopt the same identifier type and have the same communication protocol, it is determined whether the target unique identifier in the target broadcast information exists in the identifier set, and if the target unique identifier does not exist, the unique identifier (C00000000003) of the disconnected external slave device C in the identifier set is replaced by the target unique identifier (C00000000004).
In this embodiment, by checking whether there is an external slave device disconnected at preset intervals, it can be ensured that effective communication between the intelligent electric energy meter and the external slave device can be quickly achieved after the external slave device is replaced, and stability of a system in communication connection with the intelligent electric energy meter is ensured.
As an optional implementation manner, in an embodiment of the present invention, after establishing a connection with the slave device, the slave device is the intelligent electric energy meter, and further includes: and sending a request command frame to a Bluetooth module of the intelligent electric energy meter.
