Low-voltage shunt switch monitoring device and method

The invention relates to a low-voltage shunt switch monitoring device and method. The device comprises an acquisition module, a metering module, a control module and a storage module, the acquisition module is used for acquiring electrical quantity data of each phase of the low-voltage shunt switch and converting the acquired electrical quantity data to obtain secondary electrical quantity; the metering module is used for digitizing the secondary electrical quantity to obtain a digitized electrical quantity; the control module is used for reading the digital electrical quantity from the metering module, storing and transmitting the digital electrical quantity; and the storage module is used for storing the digital electrical quantity read by the control module. According to the device, electrical quantity data of the multi-path low-voltage shunt switch is acquired through the acquisition module and then is processed by the metering module, so that the data can be received by the control module and stored in t
