It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, fig. 1 is a schematic diagram of an electric energy meter structure of a hardware operating environment according to an embodiment of the present invention. The electric energy meter may include: a processor 1001, such as a CPU, a network interface 1003, a memory 1004, a communication bus 1002. Wherein a communication bus 1002 is used to enable connective communication between these components. The network interface 1003 may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface). The memory 1004 may be a high-speed RAM memory or a non-volatile memory (e.g., a disk memory). The memory 1004 may alternatively be a storage device separate from the processor 1001. It is understood that the electric energy meter should further include a display screen, and optionally, the electric energy meter may further include RF (Radio Frequency) circuits, sensors, audio circuits, WiFi modules, and the like.
The invention provides a data configuration method of an electric energy meter.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a data configuration method of an electric energy meter according to the present invention, where the data configuration method of the electric energy meter includes:
s100, receiving each data sub-packet sent by an upper computer according to a time sequence, and sequentially storing each data sub-packet in a cache region;
the host computer is used for setting parameters of the electric energy meter, and when a relatively large data packet needs to be transmitted, the host computer can only receive the relatively small data packet once due to the limitation of a Random Access Memory (RAM) memory in the electric energy meter, so that the host computer can often transmit the relatively large data packet in a sub-packet mode, namely, the relatively large data packet is divided into a plurality of relatively small data sub-packets and sequentially transmitted to the electric energy meter to realize the normal transmission of data.
It is understood that the upper computer can be a PC or a mobile phone having a function of processing data, but not limited thereto. It should be noted that, in an embodiment, a user may directly generate, by operating the upper computer, relevant data information for performing data configuration on the electric energy meter, convert the data information into a data packet that conforms to a standard communication protocol and is recognizable and receivable by the electric energy meter, and send the data packet to the electric energy meter, so as to upgrade firmware or update parameters of the electric energy meter. In another embodiment, a user can also generate relevant data information for data configuration of the electric energy meter by operating an external device connected with the upper computer and send the data information to the upper computer, and the upper computer receives the data information, converts the data information into a data packet which conforms to a standard communication protocol and can be identified and received by the electric energy meter, and sends the data packet to the electric energy meter so as to realize firmware upgrade or parameter update of the electric energy meter.
The cache region may be referred to as a flash cache.
Step S200, checking whether each data packet in the buffer area has abnormal receiving;
the receiving abnormality includes that at least one data sub-packet is missing from the data sub-packets received by the electric energy meter, the sequence of each data sub-packet is disordered, and if the data sub-packets received by the electric energy meter are incomplete or disordered, the parameter configuration of the electric energy meter is wrong, and further the function operation of the electric energy meter is abnormal.
Further, before the step S200, the method further includes:
step a, judging whether a preset sending completion identifier is received or not;
the step S200 includes:
step b, if receiving the sending completion identifier, executing: and checking whether each data sub-packet in the buffer area has abnormal receiving.
It should be noted that, when the electric energy meter receives the preset sending completion identifier, it is determined that all of the plurality of data sub-packets split from the data main packet have been received. In an embodiment, the preset sending completion identifier is a "last block", and when the electric energy meter receives the sending completion identifier of the "last block", it is determined that all the data sub-packets split from the data main packet are completely received, and at this time, it may be started to check whether all the data sub-packets in the buffer area have abnormal receiving.
Further, the data configuration method in the embodiment of the present invention further includes:
and if the sending completion identifier is not received within a preset time length from the time when the data packet sent last time is received, determining that abnormal receiving exists.
It can be understood that the electric energy meter does not receive the sending completion identifier due to unstable network communication signals, and if the sending completion identifier is not received, it can be determined that the data sub-package received by the electric energy meter has incomplete reception or disordered storage sequence to a great extent, so that it can be determined that abnormal reception exists, and the correctness and stability of the parameter configuration of the electric energy meter are improved.
Step S300, if the receiving abnormity is determined, cleaning each data sub-packet in the cache region, and sending data configuration failure information to an upper computer so that the upper computer can resend the data sub-packets;
the data configuration failure information can also comprise a trigger instruction which enables the upper computer to trigger to generate early warning information, so that a user can know the data configuration failure of the upper computer.
In step S400, if it is determined that there is no reception anomaly, each data packet in the cache area is transferred to the destination address storage area for storage.
The method for storing the data packets in the cache area comprises the following steps of transferring each data packet in the cache area to a destination address storage area for storage, and specifically comprises the following steps: and after copying each data sub-packet of the cache region, storing the data sub-packet into a destination address storage region, and emptying each data sub-packet of the cache region when the destination address storage region finishes storing each data sub-packet.
The embodiment does not adopt the existing method of receiving each data sub-packet sent by an upper computer according to a time sequence and sequentially and directly storing each data sub-packet to a destination address storage area, thereby avoiding the condition that the parameter configuration of the electric energy meter is wrong, which causes the abnormal operation of the function. The embodiment comprises the steps of firstly receiving each data sub-packet sent by an upper computer according to a time sequence, sequentially storing each data sub-packet in a cache region, checking whether each data sub-packet in the cache region has a step of abnormal reception, so as to judge whether the conditions of incomplete data sub-packet reception or disordered data sub-packet storage sequence exist, and further, if the abnormal reception exists, cleaning each data sub-packet in the cache region, and sending data configuration failure information to the upper computer, so that the upper computer resends the data sub-packet, thereby timely finding out abnormal data transmission, preventing the conditions of missing of the data sub-packet received by an electric energy meter and disordered data sub-packet storage sequence caused by various external interference factors such as network communication signals, and further avoiding the conditions of program runaway or dead halt of the electric energy meter caused by wrong parameter configuration of the electric energy meter, and ensuring the normal operation of the functions of the electric energy meter, and further performing the step of transferring each data packet in the cache area to a destination address storage area for storage if the receiving abnormity does not exist, so as to finish the firmware upgrade or parameter update of the electric energy meter and realize the correct configuration of the parameters of the electric energy meter. The embodiment provides a new data verification mechanism, overcomes the defects of the existing parameter configuration method, and can ensure the correctness and reliability of the parameter configuration of the electric energy meter.
It should be noted that, when at least one data sub-packet is missing in the data sub-packets received by the electric energy meter due to unstable network communication signals, the embodiment does not adopt a scheme of retransmitting the missing data packet by the upper computer, but instead adopts a method of clearing each data sub-packet in the buffer area and transmitting data configuration failure information to the upper computer so that the upper computer retransmits the data sub-packet, thereby avoiding that the electric energy meter receives repeated data sub-packets due to the delay of receiving the data sub-packets, and it should be noted that the missing data sub-packets are retransmitted by the upper computer, which may cause a disorder of the data sub-packet storage sequence.
Further, the step of transferring each packet of data in the cache area to the destination address storage area for storage includes:
c, splicing the data sub-packets in the cache region to obtain a data total packet;
as will be understood by those skilled in the art, each data sub-packet has a corresponding flag bit, and each flag bit stores a sequence number, such as 0, 1, 2, and 3 … …, and a data total packet can be obtained by combining each data sub-packet in the buffer according to a standard combination rule according to the sequence number of the flag bit corresponding to each data sub-packet.
And d, transferring the data total packet to a destination address storage area for storage.
In this embodiment, a data total packet is obtained by splicing the data sub-packets in the cache region; therefore, the storage efficiency of transferring the data total packet to a destination address storage area for storage is improved, and the configuration efficiency of the electric energy meter for parameter configuration is further improved.
Further, after the step of transferring each packet of data in the cache area to the destination address storage area for storage, the method further includes:
and sending the information of successful data configuration to the upper computer.
According to the implementation, the information of successful data configuration is sent to the upper computer, so that the information can be fed back to the working personnel at the first time, and the parameters of the electric energy meter are successfully configured.
Further, the step of receiving each data packet transmitted by the upper computer in time sequence includes:
step e, judging whether a multi-packet identifier sent by an upper computer is received;
step f, if the multi-packet identifier is received, determining that the upper computer sends data in a packet mode;
and if the multi-packet identifier is not received, determining that the upper computer transmits data in a total packet mode.
The step of receiving each data sub-packet sent by the upper computer according to the time sequence comprises the following steps:
and h, receiving each data sub-packet sent by the upper computer according to the time sequence if the upper computer is determined to send the data in the sub-packet mode.
It should be noted that the multi-pack flag identifier is preset by those skilled in the art, for example, the multi-pack flag identifier is "multi-pack flag". When the electric energy meter receives the preset multi-packet mark identifier, the upper computer is confirmed to transmit in a sub-packet mode, namely, a larger data total packet is divided into a plurality of smaller data sub-packets and sequentially sent to the electric energy meter so as to realize normal transmission of data.
Still further, after the step of determining whether the multi-packet flag identifier sent by the upper computer is received, the method further includes:
step i, if the multi-packet identifier is not received, determining that the upper computer sends data in a total packet mode;
and j, receiving a data total packet sent by the upper computer, and directly storing the data total packet to a destination address storage area.
It can be understood that, if the electric energy meter does not receive the preset multi-packet flag identifier, it is determined that the upper computer transmits the identifier in a total packet manner, that is, a smaller data total packet is directly sent to the electric energy meter (the data total packet is not split into a plurality of data sub-packets). Because the data total packet does not have the conditions of data packet missing and disordered storage sequence caused by various external interference factors such as unstable network communication signals, the data total packet can be directly stored in the destination address storage area, and the parameter configuration efficiency of the electric energy meter is improved under the condition of ensuring the correct parameter configuration of the electric energy meter.
Further, referring to fig. 3, which is a schematic partial flow chart of a second embodiment of the data configuration method of the electric energy meter according to the present invention, based on the first embodiment, the step S200 includes:
step S210, receiving a preset theoretical check value sent by an upper computer;
step S220, calculating to obtain an actual check value in a preset check mode according to the zone bit information of each data sub-packet in the cache region;
as will be appreciated by those skilled in the art, there is corresponding flag information for each packet.
Step S230, comparing the theoretical verification value with the actual verification value;
if the receiving abnormity is determined to exist, the step of cleaning each data sub-packet in the cache region comprises the following steps:
step S310, if the theoretical check value is inconsistent with the actual check value, cleaning each data sub-packet in the cache region.
If the theoretical check value is consistent with the actual check value, determining that no receiving abnormity exists; and if the theoretical check value is inconsistent with the actual check value, determining that receiving abnormity exists.
In one embodiment, the predetermined check mode is a crc (cyclic Redundancy check) check mode. As will be understood by those skilled in the art, CRC, i.e., cyclic redundancy check, is one of the most commonly used error checking codes in the field of data communication, and is characterized in that the lengths of the information field and the check field can be arbitrarily selected. For example, a CRC16 check method is adopted, the data check formula is X16+ X12+ X5+1, and calculation is performed by combining flag bit information of each data packet, and by the check method, only 1/65536 error probability exists for a random number of 2 bytes, so that accuracy of data check can be greatly improved. For another example, the upper computer calculates the check value of 4 bytes of each data packet by using the CRC32 check method, and then compares the calculated actual check value with the theoretical check value sent by the upper computer.
In another embodiment, the preset verification method is as follows: and verifying whether the data length is correct. The actual check value is the actual length of the data total packet, and the theoretical check value is the theoretical length of the data total packet. The preset checking mode is as follows: determining the data length of each data sub-packet according to the zone bit information corresponding to each data sub-packet in the cache region; calculating the actual length of the total data packet according to the data length of each data sub-packet; comparing the actual length of the data total packet with the preset theoretical length of the data total packet sent by the upper computer; if the actual length is consistent with the theoretical length, determining that no receiving abnormity exists; and if the actual length is inconsistent with the theoretical length, determining that receiving abnormity exists.
In another embodiment, the preset verification method is as follows: and verifying whether the sequence of storing the data sub-packets in sequence is correct or not. The actual check value is the actual ordering of the sequence numbers of the data sub-packets which are stored in sequence, and the theoretical check value is the theoretical ordering of the sequence numbers of the data sub-packets which are stored in sequence. The preset checking mode is as follows: determining the actual sequence number corresponding to each data sub-packet according to the zone bit information corresponding to each data sub-packet in the cache region; determining the actual sequence of the sequence numbers of the data sub-packets stored in sequence according to the actual sequence numbers corresponding to the data sub-packets and the storage positions corresponding to the data sub-packets; comparing the actual sequence with a theoretical sequence of sequence numbers which are stored in sequence by each data sub-packet sent by an upper computer; if the actual ordering is consistent with the theoretical ordering, determining that no receiving abnormity exists; and if the actual sequence is inconsistent with the theoretical sequence, determining that receiving abnormity exists.
As can be understood by those skilled in the art, the storage order of the data sub-packets may be determined according to the storage locations of the data sub-packets in the buffer.
In the embodiment, an actual check value is calculated in a preset check mode by receiving a preset theoretical check value sent by an upper computer and according to the zone bit information of each data sub-packet in a cache region; and comparing the theoretical check value with the actual check value, so as to judge whether the conditions of receiving abnormity, such as incomplete receiving of each data packet or disordered sequence of storing each data packet, exist, find out data transmission abnormity in time, prevent the conditions of program runaway or crash of the electric energy meter, and the like, caused by parameter configuration errors of the electric energy meter, ensure the normal operation of the functions of the electric energy meter, and further overcome the defects of the conventional parameter configuration method.
In order to facilitate a thorough understanding of the present invention, the following example of the present invention is given, and many specific details are set forth in the following example of the present invention in order to provide a thorough understanding of the present invention. The invention can be implemented in many ways other than those described herein and those skilled in the art will appreciate that the invention is not limited to the first embodiment without departing from the spirit of the invention.
Referring to fig. 4, fig. 4 is a schematic flow chart illustrating a data configuration method of an electric energy meter according to an embodiment of the present invention. The following is a specific implementation procedure of the first embodiment, which is:
(1) the electric energy meter judges whether the received data is multi-packet data;
according to the standard communication protocol of the electric energy meter, when data is divided into a plurality of packets of data, a plurality of packets of marks are generated, and the data received by the electric energy meter can be determined to be the plurality of packets of data according to the plurality of packets of marks.
(2) Sequentially storing the multiple packets of data into a cache flash;
the storage position of the next packet of data in the cache flash can be obtained by accumulating the data length of each packet, and the total length of the whole data packet can be obtained after all data are received.
(3) Judging whether the received data is complete;
and if the CRC (cyclic Redundancy check) of the data received in the cache flash is the same as the CRC sent by the upper computer, the electric energy meter can determine that the received data has no problem.
(4) Transferring the data in the cache flash to a destination address;
at this time, knowing the total length of the received data, the data in the cache flash is transferred to the destination address.
In the conventional communication field, when dealing with the above packetization, the data packets received first are often buffered in a random access memory (ram), and after all the data packets are received completely, whether the data is complete is checked, and if the data is complete, all the data is successfully received. However, in the field of electric energy meters, since hardware RAMs of the electric energy meters are generally small, it is difficult to adopt the RAMs for caching. According to the method, the received data packets are stored in the cache flash, and after all the data packets are successfully received, the data in the cache flash are transferred to the destination address in the electric meter, so that the flash transfer can be used for overcoming the defect of low hardware resources of the electric energy meter, resources are saved, receiving errors of a plurality of packets of data are avoided, and the normal operation of the functions of the electric energy meter is ensured.
The invention also proposes a readable storage medium on which the computer program is stored. The readable storage medium may be the Memory 1004 in the electric energy meter of fig. 1, and may also be at least one of a ROM (Read-only Memory)/RAM (Random Access Memory), a magnetic disk, and an optical disk, where the storage medium includes several pieces of information for enabling the electric energy meter to perform the method according to the embodiments of the present invention.
