Problems solved by technology

Therefore, there are many warning messages of the same type, and they are repeated. Some may receive nearly 50 pieces of the same message in half an hour, which seriously affects the processing of real potential equipment failure warning messages. The mobile phone expenses of personnel have increased the burden, and some operation and maintenance personnel have turned off the SMS sending function of the monitoring device, so that the due smart equipment cannot better play its benefits

Embodiment Construction

[0022] Combine below Figure 1 to Figure 3 The present invention will be described in detail.

[0023] A method for remote monitoring of fault information of a low-voltage power distribution cabinet. A controller is provided in the low-voltage power distribution cabinet, and the controller communicates with Flash memory, GSM and GPRS communication modules. The fault monitoring point of the low-voltage power distribution cabinet is provided with a data collection point. The controller communicates with the data collection point to collect data. 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 collection times, and the warning value is pre-stored in the controller. and 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 early warning method. Verifications of data of warning information are screened step by step through internal judgment programs of a controller in a low-voltage switch box, and warning information accuracy is improved; early 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 single and double judgments, the early 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 early 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 fault early warning method for 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 various monitoring sys...
