a voltage sensor: the voltage sensor is arranged inside the dark shell (1) and used for detecting the output voltage of the first double-hole jack;
the first current sensor: the first current sensor is arranged inside the dark shell (1) and used for detecting the output current of the first double-hole jack;
and a second current sensor: the second current sensor is arranged inside the dark shell (1) and used for detecting the output current of the first three-hole jack;
a timer: the timer is used for detecting the time when the current passes through the first double-hole jack and the first three-hole jack;
controller, alarm: the controller is electrically connected with the voltage sensor, the current sensor I, the current sensor II, the timer and the alarm;
the controller controls the alarm to work based on the voltage sensor, the first current sensor, the second current sensor and the timer, and comprises the following steps:
step 1: the controller calculates the theoretical output current average value I of the first double-hole jack in the detection period according to the formula (1)avg；
Wherein IavgThe average value of the theoretical output current of the first double-hole jack in the detection period is shown, and S is the total area of the first double-hole jack; p is the electron charge amount; m iskThe difference value between the maximum detection value and the minimum detection value of the first current sensor in a detection period is obtained based on the timer; heThe maximum slope of a current change graph is drawn based on a detection value of the current sensor; l isrThe contact area between the metal insert inside the first double-hole jack and the plug is the same as the contact area between the metal insert inside the first double-hole jack and the plug; z is the cross-sectional area of the wire connected with the plug; i is3Is the input current of the socket; lambda [ alpha ]pResistance of the wire for plug connection, RtIs a unit time; p is the input power of the wire connected with the plug corresponding to the first double-hole jack; u is the detection value of the voltage sensor;
then, based on the theoretical output current average value I of the first double-hole jackavgCalculating the maximum value I of the theoretical output current of the first double-control jackMAX；
Wherein G is the thermal resistance of the electric wire connected with the plug corresponding to the first double-hole jack; gamma raytThe surface temperature of the wire connected to the plug corresponding to the first dual-hole jack; o isxThe conduction voltage loss of the metal insert and the plug is reduced; i is2Outputting a current average value for the first three-hole jack theory, and acquiring the current average value based on a current sensor III; i is3Is the input current of the socket; e is a natural constant, and the value is 2.72; gamma ray0Is ambient temperature;
and when the maximum value of the theoretical output current of the first double-control jack is larger than a preset value, the controller controls an alarm to give an alarm.
