Description

A kind of GSM house intelligent controller

Technical field

The utility model relates to appliance controller, specifically a kind of GSM house intelligent controller.

Background technology

Home intelligence product in the market mainly adopts dialing technology and local area network (LAN) TCP/IP technology.The dialing technology is meant that the alarm signal and the control signal of the family intelligent control system of user installation transmit by telephone wire, the user is by dialing home phone number, electrical equipment is within doors controlled, when breaking out of fire, gas leak in the house, break in and when being in an emergency, main control system can be dialed the telephone number of storage in advance automatically by telephone wire, after treating closing of the circuit, with the voice suggestion what happens.The family intelligent control system of local area network (LAN) TCP/IP technology then arrives the Property Management of residence center with the various alarm signals in the house by Network Transmission, by of the situation to the greatest extent row processing of Property Management of residence center to taking place in the resident family house, the problem that adopts this technology is that alarm signal can't directly send the user to, coverage is short, reliability, confidentiality, fail safe are all not so good, and taking telephone wire, alarm signal and control signal can't transmit when conversing or shutting down.Especially when you went on business in the other places, when alarm signal or you controlled the equipment of family by handset dialing, you will pay long-distance telephone expenses.When adopting Internet technology as the Long-distance Control means, at first to look for an online computing, a telephone wire also will be arranged, apparatus expensive, and can not carry.Operation control is complicated, needs special study just can grasp, and it is very inconvenient to use.No matter be by dialing technology or Internet technology, its fatal shortcoming is that anti-destructive is relatively poor, in case telephone wire is cut off destruction, warning message can't send to the external world.

Summary of the invention

The objective of the invention is the problem at present home intelligence product technology existence, providing a kind of can send to the mode of the alarm signals such as distress call in the user house with the GSM short message on the user mobile phone accurately and timely.

Technical scheme of the present invention is: utilize instruction of GSM short message transmitting control and alarm signal.Gsm communication module in the GSM house intelligent controller is delivered to CPU with its content after receiving the GSM short message that user mobile phone sends, CPU resolves its content, is converted to the radio signal to electrical equipment control again, is sent to controlled electrical equipment and moves.And when in the house abnormal conditions taking place, such as the infrared ray mobile detector detect have in the house that the people walks about, door and window is pried open, smog probe detection during, and imflammable gas detector when detecting airborne combustable gas concentration and reaching dangerous values to smog that fire causes, probe will send wireless alarm signal to controller, the CPU of controller receives after the alarm signal that the gsm communication module in main frame is sent the instruction that sends SMS message immediately, the gsm communication module sends to short message on the user mobile phone again, shows concrete alarm content on user mobile phone.Of the present utility modelly specifically constitute: circuit part is by constituting with the lower part, i.e. main control system CPU, gsm wireless communication module, display part, radio receiving transmitting module, keyboard portion, power unit, watchdog circuit, 485 bus drivers, storage control; The each several part circuit all is connected with CPU, is controlled by CPU.

The utility model controller combines with GSM network, mobile phone and radio alarming probe and smart jack can realize following function:

1, remote unlocking: it is that available GSM mobile handset realizes long-range or strange land control door lock that the user need not to reach the spot.

2, household remote:, carry out Long-distance Control as microwave oven, electric rice cooker, air-conditioning, television set etc. to household electrical appliance.

3, burglar alarm: when family takes place to trespass (leaping in through the window) as the robber, microwave moves inductive probe, glass breakage detector or door status switch and triggers warning automatically, will occur warning message on the user mobile phone and the robber occur with prompting user family, simultaneously, if user applies internet services, this alarm signal will mail to 110 alarm centers automatically, obtains the processing of public security department.In addition, if the back of going out find to forget when setting up defences, can realize that long distance wireless sets up defences with mobile phone; After the householder goes home to open the door with mobile phone, will withdraw a garrison automatically after the system validation password is errorless.

4, fire alarm: when family met accident event of fire, user mobile phone will receive in time that fire alarm signal and fire compartments number point out you to deal with as early as possible.If user applies internet services, fire alarm signal will in time send to 119 FCCs to obtain relief.

5, coal gas leakage alarming: when kitchen or bathroom generation gas leak, gas leakage alarm is triggered, and alarm signal mails to user mobile phone via the GSM house intelligent controller at once.The user can send the short message instruction of closing the total lock of coal gas to family by mobile phone closes gas piping.

6, distress call: when family meets accident emergency (in case of moving hold, medical first aid), the household can press the SOS button, distress signal will appear in user mobile phone at once, simultaneously, distress signal can send to corresponding emergency department (110 alarm centers, 120 medical first aid stations) so that succoured accordingly.

7, estate management: the alarm condition of all resident families and the on off state of each family turnover door lock can be monitored in the Property Management of residence center.Except the safety precaution to the sub-district realizes the unified monitoring, can also realize sub-district building management, resident family's management, toll administration, report management etc. for repairment, resident family only needs on the GSM house intelligent controller gently one by the network system that can connect the estate management center, and obtains making appropriate arrangements in the shortest time and service.

Controller of the present utility model can be accurately and timely breaking out of fire in the user house, break in, alarm signal such as combustible gas leakage, distress call sends on the user mobile phone in the mode of GSM short message.No matter can reduce the operating cost of system, be that the user sends instructions short message to control system or control system sends alarm signal to user mobile phone, and each expense all is 0.10 yuan, so can save user's expense greatly.Can strengthen confidentiality.The content-encrypt algorithm of short message is very complicated, hardly may decode, and the voice signal of phone then is easy to be monitored.Can carry out remote wireless control and reception.So long as the place of the GSM network coverage can use mobile phone to carry out long-range electrical equipment control and alarm signal reception.Can improve anti-destructive.Because it is indoor that native system equipment all is installed in, and do not have holding wire to lead to outside the house, so difficult destruction.
