The embodiment of the invention provides a collection display method for battery testing, and the main flow of the method is described as follows.
As shown in fig. 1:
step 1000: acquiring acquisition information sent by an upper computer.
The acquisition information sent by the upper computer can be sent according to different modes, one of the acquisition information can adopt a triggering mode, and the other acquisition information can adopt an intermittent and cyclic sending mode.
If the trigger mode is adopted, the touch screen can be obtained in a mechanical key trigger mode or in a virtual key trigger mode; the mode of triggering the mechanical key can be used for sending the acquisition information by pressing the corresponding trigger key; the virtual key triggering mode can be used for sending the acquisition information by pressing the related virtual trigger key in the interface of the corresponding software.
If the intermittent cycle transmission mode is adopted, an intermittent cycle period can be preset through the installed software platform, namely, the acquisition information is transmitted every time the intermittent cycle period passes.
The lower computer and the upper computer are communicated with each other, and the lower computer can acquire the instruction sent by the upper computer through the communication relationship between the lower computer and the upper computer, wherein the instruction comprises but is not limited to acquisition information. The communication process can be wired communication or wireless communication, and the wireless communication has various types and structures, such as a WiFi module, a 3G module, a 4G module, a 5G module and the like, and the communication process utilizes the resource networking of a link network to provide remote communication or remote control function. A linked network generally refers to a public, intra-enterprise, home, or other general or private network. The common link network includes a wired network, a wireless network, a satellite network, etc., and may be one of the three, or two or a mixture of the three. The network interfaces and protocols involved in the wireless communication may be: satellite network interfaces and protocols, wireless network interfaces and protocols, wired network interfaces and protocols, and the like. The satellite network interfaces and protocols include satellite positioning interfaces and protocols, satellite communication interfaces and protocols, and the like; the wireless network interfaces and protocols include wireless positioning interfaces and protocols, wireless communication interfaces and protocols, and the like; wired network interfaces and protocols have wired positioning interfaces and protocols, wired communication interfaces and protocols, and the like.

Step 2000: and sequentially collecting parameter data of the battery to be detected according to the collected information and caching the collected data to form cached data.
The lower computer sequentially collects the parameter data of the battery to be detected according to the collected information, wherein the parameter data comprises all parameters related to the battery, such as open-circuit voltage, termination voltage, internal resistance, step capacity, step supply time, capacity of the capacitor, capacity of a voltage interval and the like. In the acquisition process, the same parameter data of a plurality of batteries can be acquired at the same time, and different parameter data of the plurality of batteries can also be acquired; of course, the single parameter data and the plurality of parameter data of the single battery can be collected, and the device can be set according to the actual detection requirement.
In the process of caching the acquired data to form cached data, the data can be cached once every time the data is acquired, or the data can be cached after a certain number of the data are acquired; the storage means may be a storage device such as RAM, ROM, EPROM, EEPROM, FLASH, magnetic disk, optical disk, etc. The storage component can store the cache data and the like, so that the subsequent program can be conveniently called at any time.
Step 3000: judging whether the current testing stage is finished or not according to the preset testing stage information.
The test stage information comprises a plurality of test parts, wherein the test parts can be divided according to time periods or acquired data quantity; the specific division modes of different test parts are set according to actual conditions.
If the time period is adopted for division, judging whether the current testing stage is completed or not according to whether the acquired time reaches the time period, and if the acquired time reaches the time period, indicating that the testing stage is completed; otherwise, the test stage is not completed.
If the data is divided according to the acquired data quantity, judging whether the current testing stage is completed or not is judged according to whether the acquired data reaches the preset data quantity, if so, the testing stage is completed; otherwise, the test stage is not completed.
Step 4000: if the current testing stage is not completed, continuing to collect the parameter data of the battery to be detected.
Step 5000: if the current testing stage is judged to be completed, the cache data acquired in the current testing stage is fed back to the upper computer and is encoded to form binary stream data; and simultaneously, starting the next testing stage to acquire data until all the testing stages are completed.
The data is cached one by one in a test stage, so that the reliability of data storage can be further ensured, the risk of losing all data due to special conditions such as power failure is reduced, and the safety of data storage is improved; after one-stage data buffering is completed, the buffered data obtained by acquisition is encoded to form binary stream data.
Encoding is the process of converting information from one form or format to another. The coding system comprises ASCII, national standard, GBK, BIG5, HZ code, CJK code, ISO and the like, and the types of codes comprise literal codes, electronic codes, PCM codes, nerve codes, memory codes, encryption and decoding. The codes used in the present application may be one or more of the above, and may be selected according to practical situations.
The binary stream data is formed after the encoding is finally completed.
Streams can be divided into 2 major categories, namely text streams (text streams) and binary streams (binarystreams). By text stream is meant that the data flowing in the stream is in the form of characters. In the text stream, '\n' is replaced with carriage return and linefeed codes 0DH and 0AH. And when output, 0DH and 0AH are replaced by '\n'.
Binary streams refer to sequences of binary digits that are streamed, with one byte binary ASCII codes if there are characters in the stream, and one byte binary digits if there are numbers. At the time of inflow and outflow, the 'n' symbol is not transformed, for example: 2001, the binary ASCII code in the text stream is denoted as '2' 0 '1', i.e. 50 48 48 49, occupies a total of 4 bytes. While 00000111 11010001 is shown in hexadecimal as 07D1 in the binary stream. Only 2 bytes.
Therefore, the binary stream saves space compared with the text stream, and conversion of n is not needed, so that the stream speed can be greatly increased, and the efficiency is improved. Thus, for digital streams containing large amounts of digital information, binary streaming may be employed; for streams containing a large amount of character information, the manner of text streams may be employed.
