Problems solved by technology
[0004] All of the above methods have the disadvantage of not being able to synchronize with the production charging process. Since the actual production site is composed of many relatively independent formation circuits, and the start-up time is different, the collected data loses the time reference and is not comparable. It can only be applied to the current circuit, so they only realize the function of replacing human manual testing and recording the battery voltage data of the current circuit, but cannot realize real large-scale data processing, and cannot realize batch-scale grouping of batteries in different circuits

Embodiment Construction
[0029] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0030] Such as figure 1 As shown, the relay device 10 is used as the core controller, and the collection device 20 and the third-party device 40 are both connected to the interface of the relay device 10 . The relay device 10 has powerful storage capability, communication capability and logical distribution processing capability. It is a point-to-point communication between the relay device 10 and the third-party device 40, which will allow the battery of the third-party device 40 to form the equipment CPU to directly send the collection command to the relay device 10 when needed, and after the relay device 10 obtains this command, Immediately order all the corresponding loop collection devices 20 to start collection, then collect the data collection results of each collection device 20 through the high-speed serial port, and query th...

The invention relates to a battery voltage data acquisition system, which comprises a third-party unit, acquisition units and a relay unit. The third-party unit is used for sending data acquisition instructions to each data acquisition unit; the acquisition unit is used for receiving the data acquisition instructions sent by the third-party unit through the relay unit so as to realize the acquisition of front-end formatted battery voltage data, and transmitting the acquired data to the relay unit; and the relay unit is used for receiving the data acquired by the data acquisition unit, after inquiring the time, current and information at the current step of the third-party unit, carrying out binding and layout on the data again according to a communication protocol, and then sending the data to a PC software control system. The battery voltage data acquisition system has the advantages of realizing the flexible grafting of the data acquisition system and a battery formation device, realizing the synchronization of the data acquisition and the technological formation process of the storage battery, improving the accuracy and synchronism of the test data, and realizing the large-scale production of the data acquisition system due to the adoption of a distributed architecture.
Description
technical field [0001] The invention relates to an acquisition system, in particular to a battery voltage data acquisition system suitable for battery production management. Background technique [0002] In recent years, as the scale of battery industrial production requires higher and higher automation, the distributed data acquisition system has also been initially applied in battery production management to realize online monitoring of battery formation and capacity monitoring of batteries that need to be paired. Screening and matching replaces the original manual test records, improving test efficiency and test accuracy. [0003] Generally speaking, two ways. One is stand-alone mode: it consists of operation panel, monitor (general liquid crystal display), and data acquisition module. One is the acquisition card networking mode: the PC and the data acquisition card communicate through a protocol network, and the data is transmitted to the computer for storage and analy...
