Description
Technical Field
The utility model relates to the field of battery detection, in particular to a test system based on multi-path SMBus communication.
Background
SMBus bus communication has been widely used in various scientific and technical products, such as a desktop computer reading BIOS information through SMBus, and a notebook computer reading and monitoring power consumption information of a battery in real time through SMBus. At present, when batteries with SMBus interfaces are tested and produced, each battery basically needs to be connected with an SMBus host to carry out communication test on the batteries, and when a batch of batteries with the same model need to be tested, because the addresses of all batteries are the same, a plurality of batteries cannot be tested simultaneously under the condition of one host; the solution is that a plurality of hosts are built at the same time, and each host is connected with 1 battery respectively, so that the effect of simultaneous testing can be achieved; but the problems of great inconvenience and the like are caused to the number, installation, wire pulling, debugging and the like of field devices.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims to provide a test system based on multi-path SMBus communication, aiming at solving the technical problems of low efficiency, large number of devices and high overall cost when the battery test system actually tests multi-path SMBus interface batteries and reverse charge and discharge.
In order to achieve the above object, the present invention provides a test system based on multiple SMBus communications, comprising: the system comprises a power supply module, a main control module, a plurality of SMBus bus interfaces and a storage module; the power supply module can provide power; the memory module is used for storing system configuration and parameter data; and the main control MCU is in communication connection with an SMBus interface for battery communication.
Optionally, the storage module includes a FLASH memory, and the FLASH memory is connected to the main control module through an SPI bus interface.
Optionally, wherein the power supply module comprises an AC220V management unit or a DC12V management unit.
The test system based on the multi-path SMBus communication enables the test system to be communicated with the multi-path SMBus batteries by arranging the plurality of interfaces for butting the battery SMBus configuration, thereby improving the test efficiency of the test system, reducing the requirements on hardware and reducing the installation difficulty and cost of hardware equipment.
