Detailed Description
For a better understanding of the technical content of the present invention, specific examples are set forth below, along with the accompanying drawings.

The remote control switch module is connected with the household power switch and is used for switching the working state of the household power switch according to an external control instruction.
The first signal acquisition module is coupled with the user incoming line power supply, the first electric energy signal of the user incoming line power supply is acquired according to an external control instruction according to a first preset sampling frequency, the acquired first electric energy signal is measured and then the measurement result is sent to the first signal processing module, and the first signal processing module performs data analysis on the measurement result of the first electric energy signal to judge whether the first electric energy signal is abnormal or not.
The second signal acquisition module is coupled with the branch electric wires corresponding to the intelligent socket, acquires second electric energy signals on the corresponding branch electric wires according to an external control instruction and a second preset sampling frequency, measures the acquired second electric energy signals, then sends measurement results to the second signal processing module, and the second signal processing module performs data analysis on the measurement results of the second electric energy signals to judge whether the second electric energy signals are abnormal or not and sends judgment results to the first signal processing module through a second communication link.
The first signal processing module is responsive to either of the following two conditions being true: 1) The first electrical energy signal is abnormal, 2) the second electrical energy signal is abnormal, a cut-off control signal is sent to the remote control switch module to cut off the household power switch, and abnormal information is sent to the user monitoring system through the first communication link.
The invention can detect the working voltage, current, active power, reactive power, power factor, harmonic content, electric quantity and the like of electric equipment. Taking working voltage as an example, a first sampled electric energy signal is taken as a voltage value on a user incoming line power supply, if the voltage value exceeds a first set threshold value, the fact that the voltage on the user incoming line power supply is overlarge at the moment is indicated, faults are already generated, if the capacitor is used continuously, danger is easily brought, an incoming line power supply switch can be cut off through a remote switch module, and a user is reminded of checking the incoming line power supply faults. Similarly, if the voltage value exceeds a second set threshold value, the situation that the voltage on the branch line is too high is indicated to be faulty, abnormal information can be sent to the first signal processing module, the first signal processing module controls the remote switch module to cut off the household power switch, and meanwhile, a second abnormal signal is sent to the user monitoring system, so that a user is reminded of checking whether a piece of electric equipment on the branch line is damaged or not, and the fault is eliminated as soon as possible. The detection principle of other detection parameters is similar to that of the working voltage. In some examples, comprehensive evaluation analysis can be performed by combining a plurality of detection parameters and the variation trend of the detection parameters, so as to obtain more reliable analysis results and realize early warning judgment.
The intelligent electricity safety detector is connected with the intelligent socket in a wireless mode, double monitoring of the branch equipment and the user incoming line power supply is achieved, the intelligent electricity safety detector is specifically used for monitoring the user incoming line power supply, the intelligent socket is used for monitoring the branch equipment, but control of the main gate of the indoor electric wire switch of the user is independently carried out by the intelligent electricity safety detector, control logic is simplified, tracing is convenient, the intelligent electricity safety detector is integrated with ultra-low power consumption, remote communication and intelligent control, and the intelligent level of home is embodied.
In addition, the EnOcean communication technology adopted by the invention has super anti-interference capability while ensuring the communication distance, and compared with the similar technology, the EnOcean communication technology has the advantages of low power consumption, long transmission distance, networking and support of functions of relay and the like, and can ensure the stability and the safety of the whole communication system. For example, some intelligent sockets which are close to the intelligent electricity safety detector are used as relay stations to be connected with intelligent sockets which are far away from the intelligent electricity safety detector; even, a plurality of intelligent sockets are networked to increase the communication distance and the stability of communication. The smart jack may return data to the smart security detector based on existing relay nodes in the network. When one or a part of the intelligent sockets are disconnected, the intelligent sockets in the far area can still calculate a new optimized communication path, and data is transmitted back to the intelligent electricity safety detector through other intelligent sockets.
In some examples, if the performance of the second signal processing module is lower than that of the first signal processing module, the processing time of the second collected electric energy signal is longer, and the detection sensitivity to abnormal conditions is lower, the present invention proposes the following technical scheme to improve the detection sensitivity of the whole intelligent electric safety detection device, and in particular:
if any one of the second signal processing modules judges that the second electric energy signal in the current acquisition period is abnormal, in M acquisition periods after power supply is recovered, the received metering result of the second electric energy signal is directly sent to the first signal processing module through a second communication link to carry out data analysis so as to judge whether the second electric energy signal is abnormal.
And M is a positive integer greater than or equal to 1.
After any one of the second signal processing modules determines that the second electric energy signal in the current acquisition period is abnormal, it is indicated that there is a possibility of a fault or abnormal electricity consumption on the branch, in order to improve safety performance, the detection proportion of the branch may be properly improved, for example, in M acquisition periods after the branch resumes power supply, the measurement result of the received second electric energy signal is directly sent to the first signal processing module through the second communication link to perform data analysis, so as to determine whether the second electric energy signal is abnormal. Because the processing speed of the first signal processing module is higher than that of the second signal processing module, when the branch is abnormal again, the abnormal condition can be analyzed more quickly, and the power switch can be directly and quickly cut off without communicating again.
Further, considering that the first signal processing module also needs to process the first electric energy signal acquired by the first signal acquisition module at the same time, the invention proposes the following technical scheme, so that the first signal processing module can work orderly:
And setting the set time range after the first signal acquisition module acquires the signals as the calculation time length, and counting to obtain the calculation period of the first signal processing module.
If the second signal processing module judges that the second electric energy signal in the current acquisition period is abnormal, the second electric energy signal is in M acquisition periods after power supply is recovered:
(1) And in a time range outside the calculation period, directly transmitting the metering result of the received second electric energy signal to the first signal processing module through the second communication link to perform data analysis so as to judge whether the second electric energy signal is abnormal.
(2) And in the calculation period, directly carrying out data analysis on the metering result of the second electric energy signal to judge whether the second electric energy signal is abnormal or not, and sending the judging result to the first signal processing module.
