It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
In the prior art, only a concentrator and an electric energy meter with the same communication protocol can be assembled in the same area, so that the concentrator and the electric energy meter can normally communicate with each other. At present, two electric energy meters are generally provided, one electric energy meter adopting a 645 communication protocol belongs to an old electric energy meter, and the other electric energy meter adopting a 698 communication protocol belongs to a novel electric energy meter.
For a district adopting the 645 communication protocol, namely, the communication protocol adopted by the concentrator in the district and the communication protocol adopted by the electric energy meter are both 645 communication protocols. However, when the electric energy meter in the station area is damaged or replaced, the electric energy meter adopting 698 communication protocol is usually used for replacement. Therefore, the electric energy meter and the concentrator cannot report some information which needs to be actively reported to the concentrator in time due to different communication protocols.
Based on the problems in the prior art, please refer to fig. 1, which is a schematic structural diagram of an electric energy meter 100 according to an embodiment of the present invention. The power meter 100 includes a memory 120, a processor 130, and a communication unit 110.
The memory 120, the processor 130, and the communication unit 110 are electrically connected to each other directly or indirectly to achieve data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The electric energy meter information reporting method may be stored in the memory 120 in the form of software or Firmware (Firmware) or may be a software function module solidified in an Operating System (OS) of the electric energy meter 100. Processor 130 is used to execute executable modules stored in memory 120.
The Memory 120 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like. The memory 120 is used for storing a program, and the processor 130 executes the program after receiving the execution instruction. The communication unit 110 is used for communication connection with an external system.
The processor 130 may be an integrated circuit chip having signal processing capabilities. The Processor may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; but may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, discrete gate or transistor logic device, discrete hardware components. The various methods, steps, and logic blocks disclosed in the embodiments of the present application may be implemented or performed. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
Fig. 2 is a schematic flow chart of an electric energy meter information reporting method according to an embodiment of the present invention, in order to timely notify the concentrator of some information such as electricity stealing behavior events or electricity utilization compliance overload. Referring to fig. 2, the method can be applied to the electric energy meter, and the electric energy meter is connected to the concentrator in a communication manner, and can be implemented by the following steps:
step S101, receiving the message sent by the concentrator.
Wherein the message contains information characterizing the communication protocol employed by the concentrator.
And S102, identifying a target communication protocol adopted by the concentrator according to the information used for representing the communication protocol adopted by the concentrator in the message.
And S103, when the target communication protocol is inconsistent with the current communication protocol of the electric energy meter, updating the current communication protocol to the target communication protocol.
And step S104, reporting the information to be reported to the concentrator according to the target communication protocol.
Upon receiving a message sent by the concentrator, a target communication protocol employed by the concentrator is identified. And comparing the target communication protocol with the current communication protocol of the electric energy meter, if the target communication protocol is consistent with the current communication protocol of the electric energy meter, indicating that the electric energy meter is consistent with the communication protocol adopted by the concentrator, and reporting the information to be reported to the concentrator according to the target communication protocol, namely reporting the information to be reported to the concentrator according to the current communication protocol of the electric energy meter. If the communication protocols are inconsistent with each other, the current communication protocol needs to be updated to the target communication protocol, and the reported information can be reported to the concentrator according to the target communication protocol, namely the information to be reported is reported to the concentrator according to the updated target communication protocol. Therefore, the electric energy meter updates the current communication protocol to be consistent with the target communication protocol by identifying the target communication protocol adopted by the concentrator, so that the concentrator can receive and analyze the information reported by the electric energy meter, namely the electric energy meter reports the information successfully or timely informs the concentrator of the information.
In addition, the communication protocol of the concentrator is automatically identified and automatically switched to the communication protocol consistent with the communication protocol adopted by the concentrator, so that the concentrator or the electric energy meter can be gradually eliminated, and the waste of material resources is reduced.
Continuing with fig. 2, the electric energy meter is illustratively communicatively coupled to the concentrator via the communication module. The communication module can not only forward the information of the electric energy meter or the concentrator, but also automatically send the information to the electric energy meter so as to match with the communication rate of the electric energy meter. And for the electric energy meter, the message is sent by the communication module. Whether the initial source device of the message is a concentrator or a communication module can be determined through information carried in the message.
It should be noted that, the communication module is for matching the communication rate of the electric energy meter, and may send messages of a plurality of different communication protocols to ensure successful communication with the electric energy meter without knowing the communication protocol adopted by the electric energy meter.
Alternatively, step S101 may be determined to be implemented by: and receiving a message sent by the equipment to be determined. And matching the message with preset conditions. If so, determining that the message is sent by the concentrator. The preset condition is used for identifying the equipment to be determined as the concentrator.
For example, whether the source of the message is the concentrator may be determined by the communication address type and/or the function information, and if the communication address type and/or the function information matches the concentrator, the device to be determined is the concentrator. For example, if the communication address type is a broadcast address or a wildcard address, it may be determined that the source of the message is not a concentrator, but a message automatically sent by the communication module. For another example, if the function information indicates that the meter number of the electric energy meter is read or that the address of the electric energy meter is read, it may be determined that the source of the message is not the concentrator but the message actively transmitted by the communication module. By excluding the message actively sent by the communication module, the situation of misjudgment is avoided. I.e. to avoid the situation where the concentrator cannot communicate successfully due to the identification of the wrong target communication protocol.
For example, when the module rate negotiation frame sent by the concentrator is received, the information to be reported may be directly reported to the concentrator by using the current communication protocol of the electric energy meter without executing step S103 and step S104.
For example, the method embodiments may be applied to any communication channel where an electric energy meter communicates with a concentrator. Such as carrier channel and RS-485 communication, etc.
Illustratively, when the power meter is powered up again after being powered down, the current communication protocol of the power meter is the same as the current communication protocol before the power meter is not powered down.
When the target communication protocol is a 698 communication protocol and the current communication protocol is a 645 communication protocol, fig. 3 is a second flowchart of the method for reporting information of an electric energy meter according to the embodiment of the present invention. As shown in fig. 3, the step of updating the current communication protocol to the target communication protocol in step S103 may be implemented as follows:
step S103-1, the 645 communication protocol is updated to 698 communication protocol.
Step S104 may be implemented as follows:
and step S104-1, reporting the information to be reported to the concentrator.
And step S104-2, receiving a first confirmation command sent by the concentrator.
The first acknowledgement command is used for indicating that the information to be reported is reported successfully.
When the current communication protocol is judged to be inconsistent with the target communication protocol, the current communication protocol of the electric energy meter can be modified, namely, the 645 communication protocol is modified into the 698 communication protocol. Under the condition that a 698 communication protocol is adopted, the EventOut pin is set to be at a low level, and the electric energy meter is in communication connection with the communication module through a serial interface, namely the electric energy meter is in communication connection with the concentrator through the serial interface. After receiving the first confirmation command sent by the concentrator, determining that the concentrator can receive and analyze the information to be reported, namely, indicating that the information to be reported is reported successfully.
For example, after the information to be reported is reported to the concentrator, the first acknowledgement command is not received within a predetermined time, and the reporting may be performed again. For example, if the first acknowledgement command is not received within 10s, the reporting may be resumed.
For example, in order to reduce invalid occupation of CPU resources in the electric energy meter, reporting may be repeated until a predetermined number of times is reached. For example, if the report is repeated 3 times, the information to be reported is not reported again.
For example, after the repeated reporting is unsuccessful, the information to be reported may be retained and an event log of the repeated reporting error may be recorded. The information to be reported can be reported again after all the information to be reported is reported, the information to be reported can be reported again at preset intervals, the reporting can be stopped, and the information to be reported can be displayed when relevant personnel overhaul the electric energy meter.
Illustratively, if a message including information representing the 645 communication protocol, which is sent by the concentrator in the process of non-waiting for receiving the first acknowledgement command, is received, reporting is stopped, steps S102 to S104 are re-executed, information to be reported before the switching to the 645 communication protocol is cleared, and information to be reported adopting the 645 communication protocol is re-generated and reported.
For example, when the electric energy meter adopting the 698 communication protocol is actively reported, the information to be reported may be one of an event record (which may be understood as an event log), an event (which may be understood as a number or a name of a certain event that is reported), and a status word.
For example, after receiving the first confirmation command for the information to be reported, that is, after step S104-2, the information to be reported may be deleted according to the type of the information to be reported. For example, when the information to be reported is an event and a reading command sent by the concentrator for the event is received, the information to be reported is deleted, that is, the event stored in the electric energy meter is deleted. For another example, when the information to be reported is a status word, the flag bit of the status word is reset, and the information to be reported is deleted.
When the target communication protocol is a 645 communication protocol, the current communication protocol is a 698 communication protocol. Fig. 4 is a third schematic flow chart of a method for reporting information of an electric energy meter according to an embodiment of the present invention, as shown in fig. 4. The step of updating the current communication protocol to the target communication protocol in step S103 may be specifically implemented in the following manner:
step S103-2, update 698 communication protocol to 645 communication protocol.
Step S104 may be implemented as follows:
and step S104-3, when the EventOut pin of the electric energy meter is in a high impedance state and the information to be reported is a state word, reporting the state word to the concentrator.
And step S104-4, receiving a second confirmation command sent by the concentrator for the status word, or a second confirmation command sent by the communication module for the status word. The second acknowledgement command is used for indicating that the status word is reported successfully.
When the current communication protocol is judged to be inconsistent with the target communication protocol, the current communication protocol of the electric energy meter can be modified, namely the 698 communication protocol is modified into the 645 communication protocol. Under the condition that a 645 communication protocol is adopted, when the EventOut pin is set to be in a high-impedance state, the electric energy meter is in communication connection with the communication module through the serial interface, namely the electric energy meter is in communication connection with the concentrator through the serial interface. After receiving the second acknowledgement command sent by the concentrator or the second acknowledgement command sent by the communication module, it is determined that the concentrator can receive and analyze the information to be reported, i.e. the success of reporting the information to be reported is indicated.
The communication module may be, for example, a carrier communication module, a micro power wireless communication module, a General Packet Radio Service (GPRS) module, or a CDMA module.
Illustratively, when the communication module is a carrier communication module or a micropower wireless communication module, the communication module reads a status word actively reported by the electric energy meter and forwards the status word to the concentrator, and the concentrator sends a second confirmation command to the electric energy meter for the status word after receiving the status. The concentrator reports the information such as the identification bit of the state word and the times of acquiring the state word to the master station. The master station is in communication connection with the plurality of concentrators so as to collect information acquired by the concentrators.
Illustratively, when the communication module is a GPRS module or a CDMA module, after the communication module reads the status word actively reported, the communication module sends a second confirmation command to the electric energy meter for the status word. And the communication module reports the information such as the identification bit of the state word, the times of acquiring the state word and the like to the master station.
It should be noted that, under the condition that the 645 communication protocol is adopted, when the electric energy meter has a status word that needs to be actively reported, the identification position corresponding to the status word is automatically set to a non-zero state. And when the actively reported status word meets the actively reported requirement, the EventOut pin is automatically set to be in a high impedance state.
It should be noted that, when the electric energy meter adopting the 645 communication protocol reports actively, the report is performed in the form of a status word.
For example, after receiving the second confirmation command for the information to be reported, that is, after step S104-4, the information to be reported may be deleted. The specific implementation manner for deleting the information to be reported is as follows: after receiving the second acknowledgement command for the status word, the flag of the status word may be reset, and the information to be reported may be deleted, i.e., the status word may be deleted.
Illustratively, in the case of the 645 communication protocol, when there is at least one status word that needs to be reported, it can be detected whether the flag bits of all status words are reset. And if the identification bits of all the state words are completely reset, setting the EventOut pin to be at a low level. It should be noted that when the flag bit of a certain status word remains set (i.e., set to a non-zero state), the status word is reported until a second acknowledgement command is received.
Illustratively, similar to the 698 communication protocol, if a message including information representing the 698 communication protocol sent by the concentrator is received in the process of non-waiting for receiving the second acknowledgement command, the reporting is stopped, the steps S102 to S104 are executed again, the information to be reported before the switching to the 698 communication protocol is cleared, and the information to be reported using the 698 communication protocol is regenerated and reported.
