Description

technical field [0001] The invention relates to a power system, in particular to a system for acquiring and monitoring power collection data through a bus. Background technique [0002] At present, the performance and data information of power acquisition equipment is collected and managed through the bus system. In this bus system, an active device is required, that is, the power device that actively obtains the data generated by other devices connected in series on the bus, and correspondingly equipped with passive devices. , these devices can be switching devices or protection devices in a power circuit, or devices for power control. [0003] However, there are many problems in the current technology system. For example, the stable acquisition of data cannot be guaranteed. This is mainly due to the problem of bus voltage or current, because the current method of carrier communication (PLC) is used to obtain data. Once the voltage fluctuates in a wide range, then There is...

Problems solved by technology

[0003] However, there are many problems in the current technology system. For example, the stable acquisition of data cannot be guaranteed. This is mainly due to the problem of bus voltage or current, because the current method of carrier communication (PLC) is used to obtain data. Once the voltage fluctuates in a wide range, then There is no guarantee that the components of active or passive equipment will work stably and, therefore, that continuous or efficient data acquisition will not be guaranteed

Of course, you can also choose the conventional wireless method, but the power consumption is relatively large, and the data acquisition method is relatively simple.
