[0002] In the traditional data transmission mode between the electric energy meter and the user display unit, the electric energy meter generally packages a set of data in a predetermined format, such as in the form of a structure, including data such as electricity and power. The data is encoded and sent to the user display unit. The user display unit needs to extract data from the data packet, perform parsing operations, and convert it into true value information on the display screen according to the pre-agreed format, and finally present the corresponding content on the display screen. However, when using the traditional data transmission mode, if there is new display data and the data is not within the preset data structure format, the user display unit will not be able to display it, making it impossible to add display content to the same electric energy meter, or different electric energy meters cannot display different information, which reduces user satisfaction.

[0013] Please refer to Figure 1 , Figure 1 A whole flowchart of a data communication method of a user display unit provided in an embodiment of the present specification is shown.

[0014] As Figure 1 shown, the data communication method of the user display unit can at least include the following steps: Step 101, the target electric energy meter determines at least one to-be-displayed data in the electric energy meter data based on the target display instruction.

[0015] In the embodiments of the present specification, the data communication method of the user display unit is applied to a data communication system of the user display unit, which can include one electric energy meter and one user display unit. The electric energy meter is used to collect various electric energy meter data, which can include real-time power, voltage, power demand, used power, power factor and other data. The user display unit is used to receive data information sent by the electric energy meter and display data. The electric energy meter and the user display unit are connected wirelessly or by wire through a communication link. Optionally, due to actual installation and setting requirements, the electric energy meter and the user display unit are generally physically separated, and the electric energy meter is protected by an external installation box to prevent the collected data from being tampered with maliciously.

[0016] Further, the actual installed electric energy meter can include multiple different kinds, and different time use stages or use environments have different corresponding display requirements. Therefore, after a target electric energy meter is fixed for data communication with a user display unit, the display instructions received by the target electric energy meter will also change. Moreover, not all of the electric energy meter data collected by the target electric energy meter needs to be transmitted to the user display unit, and only the corresponding to-be-displayed data according to the actual display requirement needs to be communicated and transmitted subsequently. Further, after the target electric energy meter receives a target display instruction issued by a target user in a wired or wireless form, the target display instruction is subjected to semantic analysis or instruction query, and each to-be-displayed data in the electric energy meter data that needs to be displayed can be determined.

[0017] In an implementable manner, the target electric energy meter determines at least one to-be-displayed data in the electric energy meter data based on the target display instruction, including: The target electric energy meter receives the target display instruction and determines at least one data kind corresponding to the target display instruction based on semantic analysis; According to each data kind, at least one to-be-displayed data in the electric energy meter data is determined.

[0018] In the embodiments of the present specification, the target electric energy meter can continuously receive a target display instruction issued by a target user in a wired or wireless form and perform cache covering. When no new target display instruction is received, the previously cached target display instruction can be called. Optionally, when the target display instruction is a requirement sentence, as an example, the previous stage display instruction is “real-time power and real-time power”, the current stage target display instruction is “real-time power, real-time power and real-time voltage”, and then the requirement sentence is input into the trained semantic analysis model through semantic analysis to obtain each data kind corresponding to the target display instruction, that is, “power”, “power” and “voltage”. Further, according to the determined each data kind, each to-be-displayed data is determined in the entire electric energy meter data, for example, “real-time power 100 kWh”, “real-time power 25 kW” and “real-time voltage 10 V”.

[0019] The semantic analysis model can be trained through a large number of sentence training sets. During model training, the requirement sentence in the sentence training set is determined as input, and the corresponding data kind is determined as output. Using the trained semantic analysis model, only the requirement sentence is input into the model as input, and each data kind corresponding to the requirement sentence can be obtained.

[0020] Step 102: The target electric energy meter determines truth table information corresponding to each of the to-be-displayed data based on a data-truth value mapping database, and sends each of the truth table information to a user display unit.

[0021] The truth table information is used to represent the on / off status corresponding to each LCD in the user display unit.

[0022] In the embodiments of this specification, to facilitate subsequent LCD display of the user display unit after receiving the information data transmitted by the target electric energy meter without the need for conventional model data extraction and decompression, the target electric energy meter can first convert the determined data to be displayed into corresponding truth table information. Specifically, the truth table information is used to represent the corresponding on and off states of each LCD in the user display unit. That is, after receiving the truth table information, the user display unit can directly display the required display data.

[0023] A pre-configured data-to-truth mapping database is used to convert the determined data to be displayed in the target electricity meter into corresponding truth table information. In the seven-segment LCD display in the user display unit, each digit is controlled by the on / off state of the seven segments (ag). The data-to-truth mapping database is constructed by converting the on / off states of each segment into binary code. Therefore, by querying the established data-to-truth mapping database for each data to be displayed, the corresponding truth table information can be obtained. Finally, the target electricity meter transmits the determined truth table information to the user display unit.

[0024] Each data to be displayed corresponds to a string of truth table data, and each data to be displayed includes data type and data size. As an example, the data type can be represented by a four-digit number, and the data size can be represented by an eight-digit number. For example, the data to be displayed is "real-time power 100kWh", where the preset serial number of "real-time power" can be set to 0001, and its corresponding binary code is 1111110 1111110 1111110 0110000, and the binary code corresponding to "100" in "100kWh" is 0000000000000000000000000000000000000000110000 1111110 1111110, so the complete binary code corresponding to the data to be displayed "real-time power 100kWh" is 1111110 1111110 1111110011000000000000000000000000000000000000000000000110000 1111110 1111110.

[0025] In one possible implementation manner, the target electric energy meter determines the truth table information corresponding to each of the to-be-displayed data based on a data-truth value mapping database, including: The target electric energy meter determines a target data-true value mapping database corresponding to the target electric energy meter based on the type of the electric energy meter; The target data-truth value mapping database is queried to determine the truth table information corresponding to each of the data to be displayed.

[0026] In the embodiments of this specification, different types of electric energy meters have different corresponding data-truth value mapping databases due to the different electric energy meter data and application scenarios they collect. Specifically, the two different types of electric energy meters used for enterprises and household users do not have the same order of magnitude for the corresponding data in terms of the real-time power collected. Therefore, different units of magnitude need to be used for conversion, resulting in their respective corresponding data-truth value mapping databases. Therefore, the type of electric energy meter of the target electric energy meter can be determined first, and then the target data-truth value mapping database corresponding to the target electric energy meter under the query conditions of the electric energy meter type can be determined. Furthermore, by querying each data to be displayed in the determined target data-truth value mapping database, the truth table information corresponding to each data to be displayed can be obtained.

[0027] Step 103: The user display unit displays each piece of truth table information in sequence according to the weight ranking corresponding to each piece of truth table information.

[0028] In the embodiment of this specification, since the display interface corresponding to the user display unit can only display one type of truth table information at a time, the user display unit needs to first weight all the truth table information after receiving the truth table information sent by the target electric energy meter, and then display them in sequence according to the weight sorting. Among them, the weight sorting corresponding to each truth table information can be determined by the order in which each truth table information is received in the user display unit, that is, the target electric energy meter determines the corresponding sending order as the weighted order when sending, or the weight sorting can be determined by the header information corresponding to each truth value information.

[0029] In one possible implementation, after sending each truth table information to a user display unit, the method further includes: The user display unit verifies each of the truth table information to obtain a verification completeness corresponding to each of the truth table information; An active retransmission request is generated based on the check integrity.

[0030] In the embodiments of the present application, in order to ensure the integrity of each truth table information in the transmission process, the CRC check mechanism can be used to detect the bit flip, packet loss and other data errors that may occur in the transmission process, so as to avoid display abnormalities or system misjudgment caused by error data. Therefore, the target electric energy meter can also use the CRC-16 check code to append to the tail of each truth table information after generating each truth table information. After the target electric energy meter sends each truth table information to the user display unit through the communication link, the user display unit checks each truth table information. For example, a certain truth table data is 10110011, the CRC-16 check code is 0xA1B2, and the complete data packet is 10110011 A1B2. Then, the user display unit recalculates the check value of the received truth table content, and if the check codes are completely matched (such as the CRC check values are the same), the integrity is 100%; if there is a difference, the check integrity is quantified according to the number of error bits. As an example, 2-bit error (total data length 16 bits) is detected, and the corresponding check integrity = (16-2) / 16 x 100% = 87.5%. Further, whether to send an active retransmission request to the target electric energy meter is determined according to the value of the determined check integrity.

[0031] In an implementation manner, the active retransmission request is generated based on the check integrity, and includes: comparing the check integrity with a preset integrity threshold to obtain a comparison result; when the comparison result represents that the check integrity is not greater than the integrity threshold, generating an active retransmission request and sending it to the target electric energy meter; when the comparison result represents that the check integrity is greater than the integrity threshold, maintaining a continuous check state.

[0032] In the embodiments of the present application, whether to send an active retransmission request to the target electric energy meter according to the value of the check integrity, the preset integrity threshold can be determined according to the application scenario. Assuming that the preset integrity threshold of a certain application scenario is 95%, then the determined check integrity is compared with the preset integrity threshold to obtain a comparison result. Specifically, if the comparison result represents that the check integrity is not greater than the integrity threshold, that is, the check integrity ≤ 95%, the retransmission mechanism is triggered, an active retransmission request is generated and sent to the target electric energy meter. If the comparison result represents that the check integrity is greater than the integrity threshold, that is, the check integrity > 95%, no active retransmission request is generated, and a continuous check state is maintained.

[0033] In an implementation manner, the user display unit displays each truth table information in sequence according to the weight order corresponding to each truth table information, and includes: The user display unit extracts each piece of the truth table information by slices, and determines the header slice information corresponding to each piece of the truth table information; The weight ranking corresponding to each piece of truth table information is determined based on the serial number value corresponding to each piece of header information, and the truth table information is displayed in sequence according to the weight ranking.

[0034] In an embodiment of the present specification, after the user display unit receives each truth table information, each truth table information is segmented and extracted to determine the header information corresponding to each truth table information. Specifically, each data to be displayed corresponds to a string of truth table data, and each data to be displayed includes data type and data size. As an example, the data type can be represented by a four-digit number, and the data size can be represented by an eight-digit number. That is, the header information corresponding to each truth table information is extracted as a binary code used to represent the first four digits in the complete binary code. Next, the serial number value corresponding to each header information is determined, and the weight ranking corresponding to each truth table information is determined according to the serial number value. Specifically, the header information of "real-time power" is 1111110 1111110 1111110 0110000, which corresponds to the determined serial number value 1. The header information of "real-time voltage" is , which corresponds to the determined serial number value 2. The corresponding weight order is "1 real-time power", "2 real-time voltage", and finally, according to the weight sorting, "real-time power XX kwh" is displayed first, and then "real-time voltage XX V" is displayed.

[0035] In one embodiment, the method further comprises: When the version status of the user display unit changes, determining a matching rule between a new user display unit version and an old user display unit version; Matching information corresponding to the truth table information is determined based on the matching rule, and weight rankings corresponding to the matching information are sorted and displayed according to the user display unit.

[0036] In the embodiments of this specification, after a user display unit's data communication system has been used for a period of time, the user display unit may need to undergo a hardware version update. This will cause the LCD display characteristics corresponding to the new user display unit version to change, making it impossible to directly display the information correctly according to the previous truth table information. Therefore, when the user display unit version status changes, a matching rule is required between the new user display unit version and the old user display unit version, based on a mapping transformation formula between the new LCD display characteristics and the old LCD display characteristics. Next, the truth table information is transformed according to the matching rule to obtain the corresponding matching information. Finally, the weighted ranking corresponding to the matching information is similarly ranked and displayed using the updated user display unit.
