Embodiment 1
[0061] Such as figure 1 As shown, a centralized power monitoring system includes multiple power monitoring modules 1 , multiple CAN / RS485 buses 2 , a control cabinet 3 , a local user information transmission module 4 , a cloud 5 and at least one client 6 .
[0062] Each power monitoring module 1 is used for power data or information of its corresponding electrical equipment. Wherein, each power monitoring module 1 includes a second microcontroller 11 and a fifth transceiver. Wherein, the second microcontroller is used for processing the monitored power data or information; and setting the value of the sending data filtering register of the power monitoring module 1 . The fifth transceivers are all connected to the second microcontroller 11 , and the second microcontroller 11 packs the collected power data or information and forwards them to the CAN / RS485 bus 2 through the fifth transceivers.
[0063] Wherein, the fifth transceiver includes a fifth CAN transceiver 12 and / or a...
Embodiment 2
[0093] The difference between this embodiment and Embodiment 1 is that the centralized power monitoring system also includes at least one repeater 7, and each repeater 7 is connected between the CAN / RS485 bus 2 of the upper and lower levels. , the repeater 7 is used to forward the power data or information from the CAN / RS485 bus 2 at the lower level to the CAN / RS485 bus 2 at the upper level.
[0094]This embodiment is applicable to the transmission of power supply data or information over a longer distance. In this embodiment, taking the CAN bus as an example, the CAN bus at the lowest level is connected to each power monitoring module 1, and then the CAN bus at the lowest level passes through a The repeater 7 is connected to the CAN bus of the upper level, so that the layers are classified, and finally connected to the control cabinet 3 through a CAN bus. Alternatively, the power monitoring modules 1 are connected to the above-mentioned CAN buses at all levels, and the power ...
