detailed description

As shown in Figure 1, the plug is connected to the first relay, the first relay is connected to the rectifier, the on-off of the circuit between the plug and the rectifier is controlled through the first relay, the first relay is connected to the controller, and the second The action of a relay, the rectifier is connected to the USB interface, and the USB interface is used to charge the DC charging device. The contact on the USB interface is provided with a first temperature sensor, and the first temperature sensor is connected to the controller so that the collected The temperature is sent to the controller.

A second relay is also connected to the plug, the second relay is connected to the socket, the on-off of the circuit between the plug and the socket is controlled by the second relay, the second relay is connected to the controller, and the second relay is controlled by the controller The action of the socket is connected to the second temperature sensor and the power detector respectively, the second temperature sensor is connected to the controller so as to transmit the temperature information on the socket contact to the controller, and the power detector is connected to the controller , so as to transmit the detected power information to the controller. The controller is also connected with database, LED screen and keys. The number of high-power electrical appliances, the power of high-power electrical appliances, the power-on time, the number of charging equipment, and the charging time can be input through the buttons. The database will classify and store the information input by the buttons, and the LED screen is used for human-computer interaction.

The buttons can be set to include the selection key 3, the up key 4 and the down key 5 as shown in Figure 2, the type of information is selected by the selection key, and the value of the information is set by the up key and the down key. (structure name 3.4.5)
