Description

A kind of Single-chip Controlling appliance system

Technical field

The invention belongs to electricity field, relates particularly to a kind of improvement of Single-chip Controlling appliance system.

Background technology

As huge numbers of families have been popularized in the development and the improvement of people's living standards of science and technology, landline telephone, cell phone, realize that the networking of household electrical appliance, intellectuality are possibly realized.Using existing personal communications terminal, realize being based on telephone network intelligent control of household electrical appliance equipment, both can investment reduction, be easy to promote again.But existing Single-chip Controlling appliance system generally there are that function is few and problem of poor safety performance.

The content of the invention

The present invention is aiming at the problems referred to above, there is provided a kind of function is more and a kind of Single-chip Controlling appliance system for having a safety feature.

For achieving the above object, the present invention adopts the following technical scheme that, a kind of Single-chip Controlling appliance system, including telephony interface, ring detection identification, simulation dislodging machine module, DTMF Decoder module, voice cue module, microprocessor, user's message module, control circuit and housed device, it is characterised in that：Microprocessor connects housed device by control circuit, user's message module connection microprocessor, microprocessor connection ring detection identified input port, simulation dislodging machine module input mouth, DTMF The input port of decoder module input port, voice cue module, ring detection identification, simulation dislodging machine module, DTMF The output port connection telephony interface of decoder module, voice cue module.

Used as a kind of preferred version, described microprocessor is MCU 。

Beneficial effects of the present invention.

The present invention belongs to the technology of this popular research of remote control technology based on the design of public phone network Single-chip Controlling household electrical appliances, system can realize that the environmental protection of remote control domestic electrical equipment device energy conservation, simulation owner are in scene, message-leaving function, and certain effect can be also played in terms of security protection by controlling the switch of audio frequency and video electrical equipment.Because its design chip cost it is not high, with higher practical value.

Specific embodiment

As schemed 1 It is shown, a kind of Single-chip Controlling appliance system, including telephony interface, ring detection identification, simulation dislodging machine module, DTMF Decoder module, voice cue module, microprocessor, user's message module, control circuit and housed device, it is characterised in that：Microprocessor connects housed device by control circuit, user's message module connection microprocessor, microprocessor connection ring detection identified input port, simulation dislodging machine module input mouth, DTMF The input port of decoder module input port, voice cue module, ring detection identification, simulation dislodging machine module, DTMF The output port connection telephony interface of decoder module, voice cue module.

By functional requirement, system is divided into system unlatching, control process and control and terminates three phases.The function that user can use has startup / Closing passage（Passage connects external equipment, such as electric light, computer, air-conditioning, refrigerator）, simulation owner be in scene, Modify password, modification message etc. function.System is started by carrying out detection identification to bell signal.When detecting that ringing number reaches setting value at the appointed time, system enters remotely control.User can be interacted by voice message with system.For this purpose, system must provide explanation.User is according to the information of voice message button, the function of control household electrical appliances.I.e. system can play corresponding voice message, and user carries out button operation according to prompting, and corresponding operation is performed after network analysis key information.Also need to arrange identity authentication function in simultaneity factor software, it is ensured that only validated user could operate the system to carry out judgement process to key errors.What the electric equipment that system is primarily directed in unmanned environment was controlled, i.e., user all over the world at any time operable appliance switch to provide safe living environment, therefore the requirement to security, reliability is higher.Using the function that certain anti-theft feature validated user identity control household electrical appliances outside electrical isolation technology, are should also provide on software in hardware design.

Darlington output type isolation coupling device, it is usually used in the transmission of longer-distance signal isolation, and high current, low capacitive reactance, the control of device such as rapidly switches off, and is also used for communication, remote control logic isolation, alarm monitoring circuit etc..Photoelectrical coupler can effectively suppress the noise of earth-return circuit, eliminate ground interference, make signal scene with main control end electrically completely isolated, it is to avoid master control system is by accidental damage.The device has the advantages that stability is high, price is low and single-chip microcomputer connection is simple.

When nobody home, user can be left a message under voice message by communication apparatus or be carried out remotely control to household electrical appliances.When there is incoming call, the number of times of telephone rings exceedes the number of times set by software（Such as set point number such as exceedes for the time 30s ）Afterwards, system enters automatic off-hook program, and then is interacted with user by voice message.If user press certain button as " 1 ", that is, selecting to enter remote control home Electricity Functional, the correct password for now needing user input tamper-proof identity and designing can be controlled to electric equipment.In order to prevent disabled user's Brute Force system control password, can be input into code error number of times reach 3 Subsystem will automatic hand-up mode, protection system and household electrical appliances safety.If incoming call user selects local message-leaving function, now system just can be caller message.When someone at home, and answer the call more than the automatic off-hook time set by system, user can pass through selection key temporary close program, you can stop operation.Use for the convenience of the user, in design time system voice prompted interface is provided so as to local message, automatic picking off and hanging machine, Modify password, return the functions such as previous menu.
