Embodiment 1
[0048] Please see figure 1 , figure 1 A schematic flowchart of a full-link fault diagnosis method supporting high-frequency data collection is provided for the embodiment of the present application. Among them, the full-link fault diagnosis method supporting high-frequency data collection includes:
[0049] S101 . By monitoring peripherals, monitor whether the concentrator sends an electric meter reading command to the carrier communication device, if not, report fault information of the concentrator; if yes, execute step S102 .
[0050] As an optional implementation manner, before the step of monitoring whether the concentrator sends the meter reading instruction to the carrier communication device by monitoring the peripherals, the method also includes:
[0051] The meter reading instruction for reading the positive active data of the meter is sent to the concentrator through the IoT operation and maintenance diagnostic instrument.
[0052] In this embodiment, the carrier...
Embodiment 2
[0067] Please see figure 2 , figure 2 It is a schematic structural diagram of a full-link fault diagnosis system supporting high-frequency data collection provided by the embodiment of the present application. Such as figure 2 As shown, the full-link fault diagnosis system supporting high-frequency data acquisition includes copy controllers, concentrators, power lines, collectors and electric energy meters, among which,
[0068] The copy controller monitors whether the concentrator sends the meter reading message to the collector;
[0069] If not, the copy controller reports the failure information of the concentrator; if yes, the copy controller monitors whether the electric meter receives a copy message on the power line;
[0070] If not, the copy controller reports the power line fault information; if so, the copy controller monitors whether the collector sends the meter reading signal to the energy meter; the meter reading signal is generated by the collector accordi...
