Description

Technical Field

[0001] The present invention relates to the technical field of data transmission, and particularly to a battery test data transmission method, system, device and computer-readable storage medium. Background Art

[0002] Transmitting data through network TCP is a relatively common data transmission method on the market currently. The transmission method is to serialize the structured data type into a binary byte stream and then transmit it through the network TCP protocol. Then, the receiving party also directly stores these data to the local hard disk after receiving them through network TCP. When it is necessary to view the data, these data are read from the hard disk into the memory, and the binary stream data is converted into the structured data type through deserialization to use these data.

[0003] In the field of battery detection, due to the high precision requirements of customers for data, the test data density is relatively large. Currently, the minimum test interval is 1 millisecond, that is, a data record needs to be generated every 1 millisecond. This data record contains many parameters, such as single-cell voltage, single-cell temperature, various environmental parameters, etc. In order to consider the high precision and expandability of data, many data are stored in double-precision floating-point type. In this way, one data occupies 8 bytes, which makes a large amount of network resources required during the transmission process. At the same time, it also takes a large amount of disk space for the receiving party to store these data on the hard disk.

[0004] Based on this, a new solution is needed. Summary of the Invention

[0042] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only the embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to the provided drawings:

[0043] Figure 1 The figure shows a flowchart of a battery test data transmission method provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0044] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The typical embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0046] Figure 1The figure shows a flowchart of a battery test data transmission method provided by an embodiment of the present invention. As Figure 1 shown, the battery test data transmission method includes the following steps:

[0047] Step S1: When receiving the i-th battery test data packet, generate storage data of N battery test parameters of the i-th battery test data packet by using the reference data of each battery test parameter and the test data of the N battery test parameters of the i-th battery test data packet, where i is a positive integer greater than 1, and N is a positive integer greater than 1;

[0048] Specifically, in an embodiment of the present invention, each battery test data packet includes N battery test parameters, and each battery test parameter has a test parameter identification code to ensure the uniqueness of each battery test parameter. When performing data transmission, first submit multiple battery test data packets generated by testing to the memory, and then use the values of all battery test parameters of the first battery test data packet in the memory as the reference data. Therefore, before the step S1, it further includes:

[0049] Step S0: When receiving the first battery test data packet, use the test data of each battery test parameter in the first battery test data packet as the reference data of the corresponding battery test parameter to form a first reference data set.

[0050] Specifically, in an embodiment of the present invention, the test data of the battery test parameters refers to the data generated during the battery test process; the stored data of the battery test parameters refers to the data that needs to be sent to the test host computer through Ethernet after being stored in the memory. Compare the newly generated battery test data packet with the reference data in the memory. If they are the same data items, then these parameter items are not included in the packet data. If they are different data items, they are included in the newly generated data packet, and then the newly generated data is stored in the memory, and at the same time, the corresponding reference parameter items in the memory are modified. For example, when receiving the second battery test data packet, the second battery test data packet contains N battery test parameters. Compare the test data of these N battery test parameters with the N reference data in the first reference data set one by one. If they are the same, delete this battery test parameter from the second battery test data packet. If they are different, retain this battery test parameter in the second battery test data packet, and at the same time, use the test data of this battery test parameter to update the reference data of this battery test parameter in the first reference data set. For example, the single-cell voltage of the second battery test data packet is 2V. Find the reference data of the single-cell voltage in the first reference data set through the test parameter identification code of the single-cell voltage. If the reference data of the single-cell voltage in the first reference data set is also 2V, then delete the single-cell voltage value of the second battery test data packet. If the reference data of the single-cell voltage in the first reference data set is 3V, then retain the single-cell voltage value in the second battery test data packet, and at the same time, modify the reference data of the single-cell voltage in the first reference data set to 2V. Therefore, step S1 includes:

[0051] Step S11: Use the test parameter identification code of the j-th battery test parameter in the i-th battery test data packet to search the first reference data set to obtain the reference data of the j-th battery test parameter, where j is a positive integer greater than or equal to 1 and less than or equal to N;

[0052] Step S12: Compare the test data of the j-th battery test parameter with the reference data of the j-th battery test parameter;

[0053] Step S13: When the test data of the j-th battery test parameter is the same as the reference data of the j-th battery test parameter, delete the test data of the j-th battery test parameter from the i-th battery test data packet;

[0054] Step S14: When the test data of the j-th battery test parameter is different from the reference data of the j-th battery test parameter, use the test data of the j-th battery test parameter to update the reference data of the j-th battery test parameter in the first reference data set and use the test data of the j-th battery test parameter as the stored data of the j-th battery test parameter.

[0055] In this embodiment, there are many battery test parameter items, and the change frequencies of each battery test parameter are also different. By assigning numbers to each battery test parameter in the battery test data packet, if the test data of the battery test parameter in a battery test data packet is the same as the test data of the corresponding item in the previous battery test data packet, the test data of this test parameter does not need to be stored and sent. Thus, the test data of each battery test data packet can be dynamically stored, and when sending out through the network, it is not necessary to send each battery test data packet according to the maximum number of parameters, thereby reducing the battery test data to be sent over the network, and thus saving the consumption of network transmission resources.

[0056] Step S2: Send the packaged multiple battery test data packets to the battery test host computer through Ethernet and store them in the hard disk of the battery test host computer;

[0057] Specifically, in an embodiment of the present invention, in step S1, each battery test parameter to be sent is assigned a number first, and then the parameter with the same number later is compared with the previous one. If they are the same, it is not packed into the data packet to be sent. In this way, it is not necessary to put all the parameters of each record into the buffer and send them to the host computer software through TCP. The existing storage methods directly store an entire packet of data into the send buffer and send it to the host computer software through TCP. Compared with the existing data transmission methods, the present invention can greatly reduce the network resource space occupied by data transmission. At the same time, when the host computer software stores these battery test data, the disk space required can also be significantly reduced.

[0058] Step S3: When reading the i-th battery test data packet, generate the test data of the N battery test parameters of the i-th battery test data packet by using the reference data of each battery test parameter and the stored data of the N battery test parameters of the i-th battery test data packet.

[0059] Specifically, in an embodiment of the present invention, when the customer needs to use these data, these data are read into the memory. The stored data in the first battery test packet is used as the reference data, and then the subsequent battery test packets are read into the memory. When there is no corresponding item data in the subsequent battery test packets, the reference data is taken as the battery test data of the corresponding item of this packet data. Then, the battery storage data included in the subsequent packets is used to update the corresponding reference data in the memory, so as to ensure that each battery test data item in each displayed battery test data packet is complete. Therefore, step S3 includes:

[0060] Step S31: Read the first battery test data packet, and use the stored data of each battery test parameter in the first battery test data packet as the reference data for the corresponding battery test parameter to form a second reference data set;

[0061] Step S32: Read the i-th battery test data packet, and use the test parameter identification code to find the m missing battery test parameters of the i-th battery test data packet, where m is a positive integer greater than or equal to 0 and less than or equal to N;

[0062] Step S33: Use the test parameter identification code of the missing battery test parameter to find the second reference data set to obtain the reference data of the missing battery test parameter;

[0063] Step S34: Use the (N - m) stored data of the i-th battery test data packet and the test parameter identification code of the corresponding battery test parameter to update the reference data of the corresponding battery test parameter in the second reference data set;

[0064] Step S35: Combine the reference data of the m missing battery test parameters and the (N - m) stored data of the i-th battery test data packet to form the test data of the i-th battery test data packet.

[0065] For example, first, when receiving the first battery test data packet, the stored data of the N battery test parameters included in the first battery test data packet are stored as the reference data for the corresponding battery test parameters in the second reference data set. Then, when receiving the second battery test data packet, the second battery test data packet only contains N - 2 battery test parameters. At this time, use the test parameter identification code to find that the two missing battery test parameters of the second battery test data packet are the cell voltage and the cell temperature. Use the test parameter identification codes of the cell voltage and the cell temperature to find the reference data of the cell voltage and the cell temperature in the second reference data set, and supplement the found reference data to the second battery test data packet. At the same time, update the reference data of the remaining N - 2 battery test parameters in the second reference data set to the values of the N - 2 battery test parameters in the second battery test data packet.

[0066] In this embodiment, when reading and displaying each packet of data, if a parameter that does not exist in the packet of data is found, it must be the same as the corresponding parameter in the previous packet. Then, just take the corresponding parameter in the previous packet of data to fill it, and so on, to complete the missing data items during transmission.

[0067] For the battery test data transmission provided by the present invention, when sending a battery test data packet, it is determined whether the data to be sent is the same as the previous packet. If they are the same, it is not stored. When reading a battery test data packet, the corresponding parameter value in the previous packet is retrieved through the test parameter identification code. For parameters that do not exist in the data file but are included in the corresponding record, they are filled with the corresponding parameter values of the previous packet. In this way, the battery test data that needs to be sent over the network can be greatly reduced, thereby saving a large amount of network transmission resource consumption and also saving a large amount of hard disk storage space.

[0068] Correspondingly, the present invention further provides a battery test data transmission system, including: a data generation module, configured to generate storage data for N battery test parameters of the i-th battery test data packet by using the reference data of each battery test parameter and the test data of the N battery test parameters of the i-th battery test data packet when receiving the i-th battery test data packet, where i is a positive integer greater than 1, and N is a positive integer greater than 1; a data transmission module, configured to send multiple packed battery test data packets to a battery test host computer through Ethernet and store them in the hard disk of the battery test host computer; a data reading module, configured to generate test data for N battery test parameters of the i-th battery test data packet by using the reference data of each battery test parameter and the storage data of the N battery test parameters of the i-th battery test data packet when reading the i-th battery test data packet.
