The STC12C5A60S2 singlechip is a singlechip with a single clock/machine period (1T), and the STC12C5A60S2 singlechip has 4 parallel I/0 ports with 8 bits, almost all of the I/0 ports are multifunctional I/O ports, namely P0, P1, P2 and P3, and each port has 8 corresponding pins; the scattered P4 port has 8 pins, so that the total number of the pins is 40, namely 38I/O ports and two pins of VCC and GND, wherein each I/O can be used as an input or an output independently.

The STC12C5A60S2 single chip microcomputer comprises a Central Processing Unit (CPU), a program memory (Flash), a data memory (SRAM), a timing/counter, a UART serial port, a serial port 2, an I/O interface, high-speed A/D conversion, an SPI interface, PCA, a watchdog, an on-chip R/C oscillator, an external crystal oscillation circuit and other modules.

Referring to fig. 3 and 4, in the embodiment of the present application, the OLED display panel 7, an OLED, i.e., an organic light emitting diode, is also called an organic electroluminescence display. The MOSI data pin of the OLED is named as LCD SDA, the clock pin is named as LCD SCL, the reset pin is named as LCD RST, and the design is provided with a pin LCD DC (in ICC mode, the DC pin is just used for switching write data and commands). Respectively connected with P2.0, P2.1, P2.2 and P2.3 of an STC12C5A60S2 singlechip.

Referring to fig. 5, in the data acquisition module 3 (also called as ac voltage/current power acquisition module) in the embodiment of the present invention, since the data acquisition module 3 in the embodiment is only used for acquiring the circuit load data on the socket, an off-the-shelf ac voltage/current power factor frequency power data acquisition module 3 is used for acquiring data of three measurement values.

Referring to fig. 6 to 8, in the embodiment of the present application, the first relay 4 and the second relay 6 have the same structure, and are isolated by a patch optical coupler, and the maximum load of a normally open interface is ac 250V/10A and dc 30V/10A.

The first relay 4 is connected in the circuit as an analog switch, and when the real-time metering value is equal to or exceeds the set upper limit value, the analog switch of the first relay 4 can be automatically switched off; when in the Bluetooth mode, the relay analog switch can be controlled to be switched off through the mobile phone APP.

The second relay 6 is used for switching, and is connected with the second relay 6 at the position of switching the voltage and current output to charge the mobile phone.

The first relay 4 and the second relay 6 are connected with the STC12C5A60S2 single chip microcomputer in the same way, one VCC is connected with GND, the other VCC is connected with an I/O port, and the VCC and GND are connected with the I/O port and are respectively connected with P3.4 and P3.5 of the STC12C5A60S2 single chip microcomputer.

The anodes of the four keys are respectively connected with four ports of P2.4, P2.5, P2.6 and P2.7 of the main chip STC12C5A60S2, and the cathodes are grounded.

Referring to fig. 11, the buzzer 8 in the embodiment of the present application is equivalent to an alarm device, and when the detected real-time data value is equal to or exceeds the upper limit value set by the key module 5, an alarm occurs, that is, the buzzer 8 sounds; the buzzer 8 is connected to the P1.0 port of the main chip STC12C5a60S 2.

The positive electrode of the buzzer 8 is connected to a VCC power supply, the emitter E of the triode is connected with the negative electrode of the buzzer 8, and the base B of the triode is controlled to pass through a current-limiting resistor R5 by a pin of a P1.0 port of the singlechip STC12C5A60S 2. When the level output by P1.0 is high, the transistor T1 is turned off, and no current flows through the coil, and the buzzer 8 does not sound. When the level of the P1.0 output is low, the triode is conducted, the current forms a loop, and the buzzer 8 sounds. In the design, the sound production of the buzzer 8 is controlled by the high-low level of the P1.0 output of the STC12C5A60S 2.
