According to the embodiment of the application, the control cores of the first module and the second module are integrated in the same multi-core chip, so that the first module and the second module can execute fault linkage measures more efficiently, the bottleneck problem that data transmission is carried out between the first module and the second module through a traditional communication link is avoided, the information communication interaction speed is greatly increased while the traditional cable communication interference and errors are eliminated, and the safety of an energy storage battery in an energy storage system is favorably improved.
In another embodiment, as shown in fig. 2, in the energy storage battery protection apparatus based on the energy storage system, the second module is further configured to set a data retrieving flag in a second read-write area corresponding to the second module of the information interaction area after the first to-be-transmitted data is read from the first read-write area;

The first module can also monitor a second read-write area corresponding to the second module in real time or according to a preset frequency. When the first module monitors that the data taking-out mark exists in the second read-write area, the data transmission request mark in the first read-write area can be further reset. The second module may monitor the first read-write area all the time, and after the second module monitors that the data transmission request flag in the first read-write area is reset, it indicates that the first module has received the information that the second module takes out the first data to be transmitted, and at this time, the second module may reset the data taking-out flag in the second read-write area. According to the data transmission method and device, after the second module reads out the first to-be-transmitted data, the data taking-out mark is set in the second reading and writing area, and then the first module resets the data transmission request mark, so that the data taking-out state of the second module can be made clear by the first module, and the data transmission method and device are convenient to use again.
In this embodiment, in the information interaction area between the first module and the second module, a first read-write area corresponding to the first module may be divided into a first read-write area and a first flag area, the first module may write the first data to be transmitted into the first read-write area, and set the data transmission request flag in the first flag area; the second read-write area corresponding to the second module may also be subdivided into a second read-write area and a second flag area, the second module may write the second to-be-transmitted data into the second read-write area, and set the data fetch flag in the second flag area.

In this embodiment, the first module may further analyze data from the second preset connection terminal according to actual requirements. Before analyzing the data at the second preset connection end, the data may be requested from the second module, and specifically, the data acquisition flag may be set in the first read-write area. The second module can monitor the first read-write area in real time, when the second module monitors that the first read-write area has the data acquisition mark, the second module can analyze second to-be-transmitted data corresponding to the data acquisition mark, write the second to-be-transmitted data into the second read-write area, and set the data response mark in the second read-write area. In addition, the first module may also monitor a second read-write area corresponding to the second module in real time, and when the data response flag is monitored in the second read-write area, it indicates that the second module has written the data into the second read-write area, and then reads the second to-be-transmitted data from the second read-write area, and resets the data acquisition flag in the first read-write area. When the second module monitors that the data acquisition flag of the first read-write area is reset, it indicates that the first module has read the desired data, and then the data response flag in the second read-write area can be reset. In the embodiment of the present application, when the first module is a grid monitoring module, the second module may be a battery monitoring module; when the first module is a battery monitoring module, the second module may be a grid monitoring module.
