The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The invention relates to a gateway data checking tool, a method and a device for checking gateway data, and aims to realize automatic checking of correctness of data converted by a gateway after a communication protocol is converted, specifically, according to the communication protocol before the gateway is converted and the communication protocol after the gateway is converted, a mapping relation between data frames with the same meaning under two communication protocols is confirmed, in the process of data conversion by the gateway, input data (namely data under the communication protocol before the gateway is converted) and output data (namely data under the communication protocol after the gateway is converted) of the gateway are collected, and the correctness of the output data is judged through the input data and the confirmed mapping relation, so that the correctness of a software program part for protocol conversion in the gateway can be judged, and the data checking is not required manually.
Embodiments of a method and an apparatus for checking gateway data and a gateway data checking tool are respectively described in detail below.
Example 1
Embodiment 1 of the present invention provides a method for checking gateway data, and fig. 1 is a flowchart illustrating steps of the method for checking gateway data according to embodiment 1 of the present invention, as shown in fig. 1, the method includes the following steps S101 to S104.
Step S101: the input data and the output data of the gateway are collected.
When data acquisition is carried out, the acquisition port is simultaneously accessed to the bus before and after gateway conversion, and then the acquisition port is controlled to carry out data acquisition. For the acquisition port, port frame format solidification can be carried out aiming at a specific gateway, the frame format of an input data acquisition port is solidified into a data frame which needs to be acquired on a bus of a communication protocol before the conversion of the specific gateway, and the frame format of an output data acquisition port is solidified into a data frame which needs to be acquired on the bus of the communication protocol after the conversion of the specific gateway, so that the acquisition port can be directly accessed into the bus without port configuration when data acquisition is carried out each time. Or before each acquisition, configuring the frame format of the acquisition port for the gateway to be checked, so as to configure the frame format of the input data acquisition port as a data frame to be acquired on the bus of the communication protocol before the conversion of the gateway to be checked, and configure the frame format of the output data acquisition port as a data frame to be acquired on the bus of the communication protocol after the conversion of the gateway to be checked.
The collected input data and output data respectively comprise at least one data frame, and each data frame is used as a data unit. For example, the physical interface of the input end before gateway conversion is a 485 communication interface, and the protocol uses a Modbus protocol, so that 03 function codes of 01-05 equipment addresses can be configured, and the number of effective data is a reply frame of 0x 44; and if the output end physical interface after the conversion of the gateway is a CAN communication interface, configuring data frames to be acquired according to a CAN protocol, such as acquiring only by using data frames with ID numbers of 0x18, 0x03, 0x01 and 0x 05.
Step S102: and judging whether the input data and the output data meet a preset mapping relation.
The mapping relation represents the relation between data frames with the same meaning under a first communication protocol and a second communication protocol, wherein the first communication protocol is a communication protocol before gateway conversion, and the second communication protocol is a communication protocol after gateway conversion.
The mapping relationship includes a position corresponding relationship between data frames with the same meaning under the first communication protocol and the second communication protocol, for example, the data frames under the first communication protocol and the data frames under the second communication protocol are respectively arranged according to the same or different predetermined sequences, and after the arrangement, the serial numbers of the data frames with the same meaning under the first communication protocol and the second communication protocol can be used as the position corresponding relationship between the data frames with the same meaning, specifically, for a certain data frame with the same meaning under the first communication protocol and the second communication protocol, the serial number in the data frame under the first communication protocol is a, the serial number in the data frame under the second communication protocol is b, and a-b is the position corresponding relationship between the data frames with the same meaning under the first communication protocol and the second communication protocol; for another example, after the data frames under the first communication protocol and the data frames under the second communication protocol are arranged according to the same or different predetermined sequence, the data frames are put into the table in sequence, the positions of the data frames with the same meaning under the first communication protocol and the second communication protocol in the table can be used as the position corresponding relationship between the data frames with the same meaning, specifically, for example, for a data frame with the same meaning under the first communication protocol and the second communication protocol, the position of the data frame under the first communication protocol in the two-dimensional table is (A1, B1), i.e. A1 th row, B1 th column, the position of the data frame under the second communication protocol in the two-dimensional table is (a2, B2), i.e., row a2, column B2, then (a1, B1) - (a2, B2) are the corresponding relationship of the positions of the frames of data with the same meaning under the first communication protocol and the second communication protocol. Or may be a location correspondence relationship of other rows, and in short, the location correspondence relationship may be used to correspond data frames with the same meaning in the first communication protocol and the second communication protocol.
The mapping relationship further includes a corresponding relationship between the data frame data values of the first communication protocol and the data frame data values of the second communication protocol, such as whether the data frame data values are equal, and the difference values. The mapping relationship also includes data precision correspondence, for example, data precision is increased or data precision is reduced, wherein the data precision refers to the number of data frames representing the same meaning.
The mapping relation is a preset relation according to the first communication protocol and the second communication protocol, and the input data and the output data meet the mapping relation, namely the process of converting the first communication protocol into the second communication protocol is correct. Specifically, when the determination is made, the mapping calculation may be performed on the input data according to the mapping relationship, and it is determined whether the calculated data is consistent with the output data, or the input data and the output data may be compared to obtain whether the relationship between the input data and the output data is consistent with the mapping relationship.
Step S103: and if the output data and the input data meet the mapping relation, determining that the output data is correct.
Step S104: and if the output data and the input data do not meet the mapping relation, determining that the output data is wrong.
By adopting the method for checking gateway data provided by the embodiment, the input data before gateway conversion and the output data obtained after gateway conversion are collected, whether the output data is correct is judged by using the mapping relation determined according to the communication protocols before and after gateway conversion, and whether the software program part for protocol conversion in the gateway is correct can be further judged, manual data checking is not needed, errors caused by manual protocol comparison are effectively reduced, and the working efficiency is greatly improved.

Step S201: and responding to the first configuration operation, configuring the data frames which need to be acquired by the input data acquisition port and the output data acquisition port.
The configuration operation of a user can be received through the touch control screen, and the frame formats of the input data acquisition port and the output data acquisition port are configured, so that the data frames required to be acquired by the input data acquisition port meet a first communication protocol, the data frames required to be acquired by the output data acquisition port meet a second communication protocol, the first communication protocol is a communication protocol before gateway conversion, and the second communication protocol is a communication protocol after gateway conversion.
Step S202: and responding to the second configuration operation to configure the mapping relation.
The configuration operation of the user can be received through the touch control screen, and the mapping relationship is configured, where the mapping relationship represents a relationship between data frames with the same meaning in the first communication protocol and the second communication protocol, which is specifically described in the foregoing embodiment 1, and details are not repeated here.
Step S203: the input data is collected through the input data collection port, and the output data is collected through the output data collection port.
Step S204: and judging whether the input data and the output data meet a preset mapping relation.
Step S205: and if the output data and the input data meet the mapping relation, determining that the output data is correct.
Step S206: and if the output data and the input data do not meet the mapping relation, determining that the output data is wrong.
By adopting the method for checking gateway data provided by the embodiment, on the basis of checking whether the gateway output data is correct or not, the gateway data checking tool adopting the method for checking network management data can be applicable to any gateway through the configuration of the input data port, the output data port and the mapping relation, and has strong universality.
Example 3
Embodiment 3 of the present invention provides a preferred method for checking gateway data based on the foregoing embodiment 1, and fig. 3 is a flowchart illustrating steps of the method for checking gateway data according to embodiment 3 of the present invention, as shown in fig. 3, the method includes the following steps S301 to S308.
Step S301: the input data and the output data of the gateway are collected.
For details of this step, reference may be made to the related contents of the above embodiments 1 and 2, and details are not repeated here.
Step S302: the data frames of the input data are arranged in a first order and the data frames of the output data are arranged in a second order.
The mapping relation comprises a position corresponding relation, wherein the position corresponding relation comprises that data frames under a first communication protocol are arranged according to a first sequence, the data frames under a second communication protocol are arranged according to a second sequence, then the data frames of input data and the data frames of output data are respectively filled in a preset first table and a preset second table, and the position corresponding relation between the data frames with the same meaning under the first communication protocol and the second communication protocol in the tables is obtained, wherein the first sequence and the second sequence can be the same or different, for example, the data frames are sequenced according to the sequence of the collected data frames, or the data frames are sequenced according to ID numbers of the data frames.
When judging whether the actually acquired output data subjected to protocol conversion by the gateway is correct, firstly, the acquired input data and the acquired output data are respectively sequenced according to a first sequence and a second sequence in sequence.
Step S303: the data frames of the input data arranged in the first order are displayed in a first table, and the data frames of the output data arranged in the second order are displayed in a second table.
After the input data and the output data are sorted, the sorted input data and output data are respectively displayed in the first table and the second table, for example, the first table is a table with N rows and M columns, when the specific display is performed, each data frame of the arranged input data is sequentially filled in the first table from the position of the first row and the first column, then the first row and the second column, the first table is sequentially filled from the position of the second row and the first column after the first row is filled, and finally all data frames of the input data are filled in the first table. The process of displaying each data frame of the arranged output data in the second table is the same.
By this step, the input data and the output data are finally displayed in the form of two tables.
Step S304: and searching each pair of data frames which satisfy the corresponding relation of positions in the input data and the output data.
After the table display is completed, each pair of data frames satisfying the position correspondence relationship in the two tables is found, for example, the position correspondence relationship includes "(a 1, B1) - (C1, D1)", a first data frame located at row a1, column B1 in the first table is found, a second data frame located at row C1, column D1 in the second table is found, and the first data frame and the second data frame are corresponding to each other to serve as a first pair of data frames. The position correspondence relationship comprises [ (A2, B2), (A3, B3) ] - (C2, D2) ] that a third data frame positioned at a line A2 and a column B2 in a first table, a fourth data frame positioned at a line A3 and a column B3 in a second table, a fifth data frame positioned at a line C2 and a column D2 in the second table are found, and the third data frame and the fourth data frame correspond to the fifth data frame as a second pair of data frames.
Step S305: and judging whether each pair of data frames meeting the position corresponding relation meets the data value size corresponding relation and the data precision corresponding relation.
For example, for the first pair of data frames, the corresponding relationship of the data value size is equal to two data frames, and the corresponding relationship of the data precision is accuracy indentation unchanged, then in this step, it is determined whether the first pair of data frames found in the step S305 are equal to each other, and if so, it is determined that the output data in the pair of data frames is correct, that is, the following step S306 is executed, otherwise, it is determined that the output data in the pair of data frames is incorrect, that is, the following step S307 is executed. If the output data in each pair of data frames are correct, the gateway is correct in the process of protocol conversion.
Step S306: and if a certain pair of data frames meets the corresponding data value size corresponding relation and data precision corresponding relation, determining that the output data in the pair of data frames is correct.
Step S307: and if a certain pair of data frames does not meet the corresponding data value size corresponding relation and data precision corresponding relation, determining that the output data in the pair of data frames is wrong.
Step S308: after the output data is determined to be erroneous, the erroneous data frame is indicated in the second table, and the data frame satisfying the positional correspondence with the erroneous data frame is indicated in the first table.
Through the step, the wrong data is marked, so that the user can conveniently and visually locate the wrong data frame, and further, the data frame of which the wrong data frame meets the position corresponding relation, namely the data frame in the input data, which has the same meaning as the wrong data frame in the output data, is marked, so that the user can conveniently find a data source and determine the reason of the error when data checking is carried out.
