The specific working principle is expressed as follows:

when the utility model discloses an after the electricity was gone up to the smart jack, the circuit began working, main control chip 7-3 initialization, the configuration is punched the card and is interrupted, button interruption and communication interruption, then read the configuration file from memory chip, obtain information such as current user information and mode, and send information to the server through wireless communication module 4-4, the server verifies user's validity and feeds back to main control chip 7-3, when user information is effective, judge the mode of this equipment, if for lasting mode, then directly put through the socket, LED pilot lamp 4-11 is green, then enter standby mode; if the mode is other mode, directly entering the standby mode, and waiting for the operation of the user, wherein the LED indicator lamps 4-11 are red; when the user information is invalid, the main control chip 7-3 modifies the intelligent socket into a card swiping mode, and then enters a standby state to wait for the operation of the user.

When the device is in a starting mode, the main control chip 7-3 reads data transmitted by the metering chip of the electric energy metering unit 6-6 and calculates the data, calculates accurate voltage, current and power, stores the data in the storage chip AT24C02, and the main control chip 7-3 sends real-time current, voltage and power to a server AT regular time through the wireless communication module 4-4, so that whether the device is in use and is used illegally can be conveniently monitored;

further, the continuous operation mode is a mode for use with an appliance that requires continuous power supply, such as a refrigerator or the like.

When the equipment is in a card swiping mode, the equipment can be started only by swiping the card, and can be closed by swiping the card or pressing keys; when the device is in a key mode, after a user swipes a card to obtain authorization, the device can be opened and closed through keys.

No matter what kind of mode this equipment is in, the server can all directly send main control chip 7-3 through switch control instruction in order to control this equipment open and close.

(1) Interrupting card swiping:

when a user swipes a card 2-2 by using an RFID card opposite to the radio frequency card, the radio frequency read-write module 4-3 reads user information in the card and transmits the user information to the main control chip 7-3, the main control chip 7-3 sends the information to a server through the radio communication module 4-4, the main control chip 7-3 receives confirmation information of the server and judges whether the card user is valid, if the card user is invalid, the standby function is entered, and the working state of the current intelligent socket is not changed; if the user information is valid, judging whether the user information is consistent with the current user information, if so, judging whether the current working mode is a key working mode, and if so, directly entering a standby function; if the current working mode is not the key working mode, judging the working state of the intelligent socket, if the intelligent socket is in the power-on state, shutting down the intelligent socket, otherwise, starting up the intelligent socket, and then entering a standby state; when the user information is not consistent with the current user information, a new user is considered to use the intelligent socket, the intelligent socket is shut down, then the current user information and the working mode of the socket are configured according to the return information of the server, then the standby function is entered, and when the user swipes the card again, if the user is not in the key working mode, the intelligent socket can be opened.

That is, the card swiping will cause the working state of the smart socket in the continuous working mode and the card swiping working mode to change without affecting the state of the smart switch in the key working mode.

(2) Key interruption:

after the key interruption is authorized by the server once, the key can be directly used for controlling the intelligent socket.

When the capacitive touch key 4-2 is pressed down, the capacitive touch key chip 4-9 reads information of a current socket and transmits the information to the main control chip 7-3, the main control chip 7-3 sends the information to the server through the wireless communication module 4-4, the server returns the information to the main control chip 7-3 after confirmation, if the user information is invalid, the standby function is started after shutdown, and the server manages user authorization conveniently; if the user information is valid, judging whether the user information is in a continuous working state and a card swiping working state, if so, directly entering a standby function without changing the current working state of the socket, and if not, changing the current working state of the intelligent socket.

(3) Communication interruption:

the interruption of communication refers to interruption caused by the server actively sending a command to the smart socket, so as to remotely control the socket or configure the working mode of the socket.

If the communication interruption occurs, the main control chip 7-3 reads a control instruction in the communication information and judges the type of the instruction, if the instruction is a switch control instruction, the current user is modified to be a server or corresponding user information according to the parameters of the instruction, if the instruction is a switch instruction, the computer is started, otherwise, the computer is shut down, and then the computer enters a standby function; if the control command is configured, configuring the working mode of the intelligent socket, and entering a standby function after configuration; and if the control instruction is inquired, the intelligent socket sends the current working information to the server and enters a standby function after the working information is finished.

(4) Timer interrupt:

the timer interrupt is divided into a metering timer interrupt and a sending timer interrupt, the metering timer interrupt and the uploading timer interrupt are configured in the starting and the shutdown, the metering timer interrupt is used for reading data of a metering chip, and the sending timer interrupt is used for sending metering information to a server. Typically, the transmit timer is longer than the meter timer.

When the interruption of the metering timer occurs, the data of the metering chip is read firstly, the relevant electrical parameters are calculated, the data, the time, the user and other information are stored in the local storage chip, and the standby function is started after the data, the time, the user and the other information are stored in the local storage chip.

When the interrupt of the sending timer occurs, the stored data is read first, then the required data and parameters are calculated, and the data are sent to the server.

Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, a plurality of modifications and decorations without departing from the principle of the present invention should be considered as the protection scope of the present invention.
