The substation box device according to claim 6, wherein an electrically controlled switch communicatively connected to the substation box device is provided on a power supply line of the target object, and the communication module controls the electrically controlled switch to be turned off to stop supplying power to the target object when receiving a first power-off signal transmitted by the power server, wherein the first power-off signal is generated by the power server when the power server resolves that the power parameter exceeds a preset threshold.
8. The substation equipment according to claim 6, wherein the substation equipment comprises at least one transformer, a power supply line of the transformer is provided with an electric control switch, the acquisition module is further configured to acquire temperature data of the at least one transformer and send the temperature data to the second processing module, and the second processing module is further configured to generate a second power-off signal when detecting that the temperature data exceeds a preset temperature threshold value, so that the electric control switch disconnects the power supply of the transformer according to the second power-off signal.
9. A power data monitoring method applied to the power server according to any one of claims 1 to 5, wherein the power server is connected with a power transformation box device in a communication mode, and the method comprises the following steps:
acquiring power parameters encrypted and transmitted by the substation box equipment according to a preset key strategy;
decrypting the power parameter according to a preset key strategy, judging whether the decrypted power parameter exceeds a preset threshold and whether the time length exceeding the preset threshold exceeds a preset time length, and generating an alarm signal when the decrypted power parameter exceeds the preset threshold and the time length exceeding the preset threshold exceeds the preset time length;
encrypting the analyzed power parameters according to a preset key strategy;
and sending the encrypted power parameters to the monitoring terminal so that the monitoring terminal sends out an alarm prompt when receiving the alarm signal.
10. The method of claim 9, wherein the power parameter comprises at least one of phase/line current, phase/line voltage, active power, reactive power, apparent power, power factor, frequency, and power usage over a first predetermined period of time;
and generating an alarm signal when at least one of the phase/line current, the phase/line voltage, the active power, the reactive power, the apparent power, the power factor, the frequency and the electricity consumption in the first preset time period exceeds a corresponding preset threshold and maintains the electricity consumption for a time period exceeding the preset time period.
