Abstract

The utility model provides an intelligent power socket based on short message service (SMS) control. The socket mainly comprises a single chip microcomputer, a GSM transceiver, a power module, a switch, a relay and plug jacks, wherein the single chip microcomputer is connected respectively with the GSM transceiver and the relay; an output terminal of the power module is connected by the switch with the single chip microcomputer, the GSM transceiver and a VCC terminal of the relay; and one terminal of each plug jack is connected with a live wire of a 220V commercial power by a normally-closed contact of the relay. The utility model can not only be used as an ordinary socket, but also realize SMS control on the intelligent power socket when the single chip microcomputer, the GSM transceiver and the relay are plugged in, thereby conveniently achieving the purpose of remotely controlling the household appliances connected thereon.

Description

Intelligent power socket based on SMS control

Technical field

The utility model relates to a kind of supply socket, specifically, is a kind of intelligent power socket based on SMS control.

Background technology

With the quickening pace of modern life, people are more and more higher for the intelligent requirements in the daily life, and traditional supply socket can only provide service by the mode of manual or indoor remote control, can't realize the Long-distance Control to the company household electrical appliances.Existing tele-control system based on GSM mainly is to adopt principal and subordinate's control model that the important household electrical appliances of not concentrating that distribute are controlled at present, and such system complex degree height costs an arm and a leg.If can allow conventional socket also have the GSM remote control function, then general electrical equipment is connected the purpose that can realize Long-distance Control on this socket easily, to bring great convenience for daily life, also will reduce the complexity of existing home appliance remote control system simultaneously.

The utility model content

The purpose of this utility model be to provide a kind of simple, cheap, cooperate the intelligent power socket that is used for the household electrical appliances Long-distance Control with mobile phone.

The utility model is achieved through the following technical solutions its purpose.

The intelligent power socket based on SMS control that the utility model is designed mainly comprises parts such as single-chip microcomputer, GSM transceiver, power module, switch 4, relay and jack 8 on the structure.

Annexation is: the output of power module links to each other with the VCC end of single-chip microcomputer, GSM transceiver and relay by switch 4; Four pins of single-chip microcomputer are connected with relay by triode respectively, with the break-make of control normally-closed contact 7; One end of jack 8 links to each other with the live wire of civil power 220V by the normally-closed contact 7 of relay, and the other end directly links to each other with zero line; The GSM transceiver is connected with single-chip microcomputer, is used to receive note and gives the single-chip microcomputer processing.The feature of switch 4 is: when switch 4 disconnected, single-chip microcomputer, GSM transceiver and relay power down provided the common socket function by normally-closed contact 7 and jack 8; During switch 4 closures, single-chip microcomputer, GSM transceiver and relay power on, and single-chip microcomputer makes four normally-closed contacts 7 be in off-state by above-mentioned four pins through relay, realizes the intelligent power socket function based on SMS control.

Beneficial effect

Utilize the folding of mobile phone remote control intelligent power socket, and then, the purpose of other household electrical appliances of realization control.

Description of drawings

Fig. 1 is a schematic diagram of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Based on the intelligent power socket of SMS control, comprise parts such as single-chip microcomputer 1, GSM transceiver 2, power module 3, switch 4, relay 5, triode 6 and jack 8 as shown in Figure 1.Single-chip microcomputer 1 links to each other with relay 5 with GSM transceiver 2 respectively, concrete connected mode is that the RXD of GSM transceiver 2 is connected with the serial ports TXD of single-chip microcomputer 1, the TXD of GSM transceiver 2 is connected with the serial ports RXD of single-chip microcomputer 1, the P1.0 pin of single-chip microcomputer 1 and the start end of GSM transceiver 2 are connected, and while P0.0, P0.1, four pins of P0.2 and P0.3 of single-chip microcomputer 1 are connected with relay 5 by triode 6 respectively; Power module 3 changes into 5V with civil power 220V, and its output links to each other with the VCC end of single-chip microcomputer 1, GSM transceiver 2 and relay 5 by switch 4; One end of jack 8 links to each other with the live wire of civil power 220V by the normally-closed contact 7 of relay, and the other end directly links to each other with ground wire.

When switch 4 disconnected, single-chip microcomputer 1, GSM transceiver 2 and relay 5 power down provided the common socket function by normally-closed contact 7 and jack 8; After switch 4 closures, single-chip microcomputer 1, GSM transceiver 2 and relay 5 power on, single-chip microcomputer 1 passes through P0.0, P0.1, the level value of four pin outputs of P0.2 and P0.3 makes four normally-closed contacts 7 be in off-state through relay 5, and the P1.0 pin of single-chip microcomputer 1 provides a low level signal, GSM transceiver 2 just can land gsm wireless network 9, the user gives GSM transceiver 2 by the SMS transmitting control commands out of doors, GSM transceiver 2 is given single-chip microcomputer 1 with the note of receiving, 1 pair of note of single-chip microcomputer is analyzed, the order that obtains according to analysis, level value by above-mentioned four pins output is controlled corresponding relays 5, during output low level, relay 5 armature adhesives make normally-closed contact 7 closures, during the output high level, relay 5 armature discharge, normally-closed contact 7 is disconnected, thereby realize switch control, realize function based on the intelligent power socket of SMS control to household electrical appliance.
