detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

As shown in Figure 1, it is an embodiment of the present invention, which proposes a smart socket based on wireless technology, which cooperates with a relay (not shown) to control household appliances (not shown), including a main controller 1, Bluetooth Communication module 2, power supply module 3, relay control circuit 4 matched with relay, reset module 5 and GSM communication module 6; bluetooth communication module 2, power supply module 3, relay control circuit 4, reset module 5 and GSM communication module 6 all Connected to the main controller 1; among them,

GSM communication module 6 can be built-in the SIM card that is used to receive the short message that user sends, is used for parsing the short message that user sends, obtains the first control command that user sends;

Bluetooth communication module 2, used to directly obtain the second control instruction sent by the user;

The main controller 1 is used to analyze the first control command and/or the second control command issued by the user, and output the corresponding level signal to the relay control circuit 4 to realize the current working state of the control relay; wherein, the level signal includes high Level signal and low level signal; the working state includes on and off; when the level signal is a high level signal, the current working state of the relay is on; when the level signal is a low level signal, the relay The current working status of is disconnected.

Among them, the chip of main controller 1 adopts ATmega8 chip; the chip of bluetooth communication module 2 adopts BlueCore4-Ext chip; the chip of GSM communication module 6 adopts SIM900 chip; reset; the chip of relay control circuit 4 adopts ULN2823A chip.

It can be understood that, in order to integrate more intelligence, the main controller 1 is also connected with a digital display module, an input and output module and a button module.

It should be noted that the current working state of the relay can be sent to the user by the main controller 1 through the Bluetooth communication module 2 and the GSM communication module 6 respectively; wherein, when the Bluetooth communication module 2 is used, the current working state of the relay is sent through the Modbus message To the user; when the GSM communication module 6 is adopted, the current working state of the relay is sent to the user by means of a short message. At this moment, the GSM communication module 6 has a built-in SIM card for receiving and sending short messages.

When the current first control command analyzed by the main controller 1 is different from the current second control command, the corresponding level signals are sequentially output to the relay control according to the current first control command and the current second control command in chronological order. Circuit 4 realizes that the working state of the control relay is first turned on and then disconnected or first disconnected and then turned on; as an example, the main controller 1 first receives the Modbus message sent by the mobile phone using Bluetooth communication, and directly obtains the message sent by the user. At present, the second control command (such as turning on the air conditioner in the living room) outputs a high-level signal to the relay control circuit 4 to realize that the working state of the control relay is conduction. If the current first control command (such as turning off the air conditioner in the living room) is different from the aforementioned second control command, a low-level signal is output to the relay control circuit 4 to realize that the working state of the control relay is disconnected, that is, the relay is first turned on and then turned off. disconnect. In the same way, the relay can be turned off first and then turned on.

When the current first control command parsed by the main controller is the same as the current second control command, the corresponding level signal is output to the relay control circuit according to the current first control command or the current second control command earlier in time to realize control The working state of the relay is on or off; as an example, the main controller 1 first receives the Modbus message sent by the mobile phone through Bluetooth communication, and directly obtains the current second control command issued by the user (such as turning on the air conditioner in the living room), Output a high-level signal to the relay control circuit 4 to realize that the working state of the control relay is conduction. After a period of time, the short message sent by the mobile phone using GSM is received, and the current second control command identical to the aforementioned second control command issued by the user is analyzed and obtained. A control command (such as turning on the air conditioner in the living room), the working state of the relay remains unchanged, that is, it is turned on.

It should be noted that the first control instruction and the second control instruction may include, but are not limited to, the ID number of the relay and its corresponding control command parameters, the custom time for executing the control command, and the like.

As shown in Figure 2, in the embodiment of the present invention, the ATmega8 chip has 23 programmable I/O ports, and the input/output direction of I/O can be defined arbitrarily; It is a push-pull output during output, with strong drive capability and can be directly driven LED and other high-current loads: the input port can be defined as a three-state input, and can be set with an internal pull-up resistor, eliminating the need for an external pull-up resistor. The core of the AVR microcontroller is to connect 32 working registers and a rich instruction set. All working registers are directly connected to the ALU (Arithmetic Logic Unit), which realizes the operation of simultaneously accessing (reading and writing) two independent registers with one instruction executed in one clock cycle. This structure improves code efficiency, making the execution time of most instructions only one clock cycle. Therefore, ATmega8 can achieve performance close to 1MIPS/MHz, and its operating speed is 10 times higher than that of ordinary CISC microcontrollers.
