Example Embodiment

[0039] Combine below Figure 1 to Figure 3 The present invention will be described in detail.

[0040] A remote monitoring method for low-voltage power distribution cabinet fault information. A controller is provided in the low-voltage power distribution cabinet. The controller is communicatively connected with Flash memory, GSM and GPRS communication modules. The low-voltage power distribution cabinet fault monitoring point is provided with a data collection point. The controller communicates with the data collection point to collect data, and a data channel is set in the controller corresponding to the data of each data collection point. The counter in the controller records the channel number and the number of data collections, and the warning value is stored in the controller in advance And the alarm value, during the operation of the low-voltage power distribution cabinet, the remote monitoring of fault information executes the following procedures in sequence:

Abstract

The invention discloses a low-voltage switch box fault information remote monitoring method which comprises the following steps of first, fault diagnosis and early warning, second, fault diagnosis, warning and isolating, and third, fault point self curing. Through internal judgment programs of a controller in a low-voltage switch box, verifications of data of early warning (warning) information are screened step by step, and early warning (warning) information accuracy is improved; early warning (warning) information which is higher or lower than preset parameters and generated at the normal electricity consumption peak is screened, and device fault possibility is eliminated; through reasonable judgment and cross use of singular judgment and double judgments, the early warning (warning) information of emergencies in the diagnosis process is further quickly sent out; the means that data are increased gradually is adopted, the problem of repeated warning sending through comparison with preset values is solved, and the fault diagnosis is more accurate and higher in efficiency.

Description

technical field [0001] The invention relates to a method for remote monitoring of fault information of a low-voltage power distribution cabinet. Background technique [0002] At present, power supply enterprises have invested heavily in the construction of intelligent power distribution equipment, and have also achieved the purpose of remote monitoring, remote parameter adjustment and fault warning. However, in practical applications, it is found that when intelligent power distribution equipment sends fault warning information through GSM or GPRS, some use the preset parameters (such as current, voltage and temperature values) near the fault point of power distribution equipment to compare with the actual data collected. In case of exceeding or decreasing the preset parameters as the basis to directly trigger the built-in wireless communication of the terminal to send information to the relevant mobile phone and remote server, and then remind in the early warning window in ...
