For example, based on the above description, if the controller 103 receives the detection result of the human body infrared sensor 101 and the infrared sensing source discharges charges outwards, it may be determined that the pre-warning object exists on the opening side of the distribution box 100. It should be noted that, if there is an early-warning object, but it is not necessary to output early-warning information to the early-warning object, because there is also a case that the distribution box 100 does not have a leakage phenomenon at this time, then the distribution box 100 will not threaten the early-warning object, and therefore, the early-warning object does not need to be pre-warned. Whether the early warning object exists on the side of the opening of the distribution box 100 is judged by the time controller based on the detection result of the human infrared sensor 101, the data is easy to obtain, complex judgment logic is not needed, the judgment result can be obtained according to the detection result, and the early warning efficiency of the distribution box 100 can be improved.
In one embodiment, the controller 103 is further configured to determine that the electrical leakage phenomenon exists in the electrical distribution box 100 when the voltage signal is collected from the box body of the electrical distribution box 100 by the voltage signal collector 102 and the voltage signal is greater than a preset threshold.
For example, whether the distribution box 100 leaks electricity is judged by judging whether a voltage signal can be collected from the box body of the distribution box 100 and the voltage signal is greater than a preset voltage threshold, if the voltage signal is collected from the box body of the distribution box 100 by the voltage signal collector 102 and the voltage signal is greater than the preset voltage threshold, the controller 103 can judge that the distribution box 100 has the phenomenon of electricity leakage, and the preset voltage threshold can be set according to the maximum voltage that a human body can bear. The voltage signal is obtained simply, complex judgment logic is not needed, the result of the electric leakage phenomenon of the distribution box 100 can be obtained as long as the voltage signal is greater than the preset voltage threshold, and the early warning efficiency of the distribution box 100 can be improved.
In one embodiment, the power distribution box 100 further comprises a temperature sensor 107 and a humidity sensor 108, wherein the temperature sensor 107 and the humidity sensor 108 are both connected to the controller 103,

and the controller 103 is further configured to regulate and control the working environment in the box body to a target state according to the temperature data and the humidity data, and the target state is used for reducing the risk level of the leakage event.
Wherein, the risk grade of the electric leakage event can be determined according to the magnitude of the voltage signal on the box body of the distribution box 100, and the larger the voltage signal, the higher the risk grade is, which means that the distribution box 100 is more dangerous. For example, the risk level of the leakage event is classified into five levels, the risk level of the five levels is the highest, the four levels are lower than the five levels, and the like. In addition, when an electrical leakage event occurs, the environment in which the electrical distribution box 100 is located may also aggravate or reduce the risk level of the electrical leakage event to some extent.
Illustratively, a temperature sensor 107 and a humidity sensor 108 are further disposed in the distribution box 100 and are respectively used for constantly acquiring temperature data and humidity data in the distribution box 100 to regulate and control a working environment in the box according to the temperature data and the humidity data, for example, when the temperature sensor 107 obtains that the temperature in the distribution box 100 is higher than a preset temperature threshold, the controller 103 may control to turn on a cooling device, such as a fan, in the distribution box 100 to cool the distribution box 100, so as to regulate and control the working environment of the distribution box 100 to a target state, and if the risk level of the leakage event is four levels before the temperature of the distribution box 100 is not lowered, the temperature of the distribution box 100 may be lowered to three levels or two levels. For another example, when the humidity sensor 108 obtains that the humidity in the distribution box 100 is higher than the preset humidity threshold, the controller 103 may control to turn on a dehumidification device in the distribution box 100 to dehumidify the distribution box 100, so as to regulate the working environment of the distribution box 100 to a target state, and if the risk level of the leakage event is four levels before the dehumidification of the distribution box 100 is not performed, the dehumidification of the distribution box 100 may be performed before the leakage event is reduced to three levels or two levels. Set up temperature sensor 107 and humidity transducer 108 for block terminal 100 and can monitor the environmental data in block terminal 100 often to make controller 103 regulate and control the operational environment in the box at any time, avoided block terminal 100's bad situation to continue to worsen.

For example, the locator 109 is, for example, a GPS locating device, which may be disposed inside the distribution box 100 or outside the distribution box 100, and the locator 109 and the controller 103 may perform wired or wireless communication, so that the controller 103 can transmit the position information of the distribution box 100 to the target terminal through the communication antenna after outputting the warning information, so as to prompt the user of the target terminal 300 to perform a maintenance operation on the distribution box 100 according to the position information of the distribution box 100. It should be noted that, as long as the controller 103 determines that the electric leakage phenomenon exists in the distribution box 100, a maintenance request can be sent to the user of the target terminal device 300 without being limited by whether or not the pre-warning object exists.
