Summary of the invention

The utility model has overcome the deficiency of prior art; Proposed a kind of intelligent household security system, set up family and sub-district security protection network, made full use of good interoperability between CAN bus network node with two-stage CAN bus architecture based on many network architectures; Real-time and the integrated initiative of height system and the good extensibility that offer the user; A kind of low cost is provided, easy to operate, rapid-action cloth planar network architecture.On type of alarm, the present invention makes full use of the PSTN network, and combines with the Internet network, and the warning and the emergence treatment scheme that have more real-time and reliability are provided, and with low cost.

The technical scheme of the utility model is: a kind of intelligent household security system based on many network architectures; Comprise household internal intelligent network, sub-district intelligent network, exterior I nternet net and PSTN network; Said household internal intelligent network adopts the CAN bus architecture; Comprise an intelligent console node and a plurality of security alarm node; Said intelligent console node module comprises micro-control unit MCU, CAN controller, CAN transceiver and demonstration and input equipment; Said intelligent console node module is provided with two CAN network interfaces, and one is inserted the CAN of family bus network, an access sub-district CAN network and a PSTN interface module, and said PSTN interface module inserts the PSTN network through holding wire.

Said sub-district intelligent network adopts the CAN bus structures; Comprise sub-district node and Network Interface Module; Said sub-district node is connected with the said access CAN of family bus network through interface, and said Network Interface Module is connected to said exterior I nternet net through external interface.

Be provided with the abnormality detection module at said security alarm intranodal; Said abnormality detection module is connected through holding wire with micro-control unit MCU; Said abnormality detection module detects unusual back and produces warning message, and MCU receives to make behind the warning message and judges and be which kind of type of alarm and note.

The utlity model has following beneficial effect:

1) system that realizes of the utility model, simpler on networking mode, cost is lower, the autgmentability of network, real-time is better.

2) the utility model is distinguished and traditional single processing mode in report to the police transmission and processing, and emergency reaction speed is faster, and protection is higher, more helps the user and makes fast processing in the short time, thereby loss is dropped to minimum.

Description of drawings

Further specify the utility model below in conjunction with accompanying drawing and embodiment.

Fig. 1 is the intelligent household security system network topological diagram based on many network architectures.

Embodiment:

Referring to shown in Figure 1, the utility model comprises the household internal intelligent network, the sub-district intelligent network, and exterior I nternet net, the PSTN network further specifies below in conjunction with accompanying drawing:

1) topological structure of household internal intelligent network

The topological structure of household internal intelligent network is as shown in Figure 1, and said household internal intelligent network adopts the CAN bus architecture, comprises a control desk node and four security alarm nodes; Be respectively cigarette sense warning node; Infrared acquisition warning node, combustible gas alarm node, door and window warning node.Household intelligent control platform node module mainly is by micro-control unit MCU, independent CAN controller, and the CAN transceiver shows and the input equipment composition with corresponding.The particularity of household intelligent control platform node need to be two CAN network interfaces, and one is inserted the CAN of family network, and one is inserted sub-district CAN network, also needs a PSTN interface module and insert the PSTN network.The network architecture of whole sub-district also adopts the CAN bus structures, and node corresponding is exactly the CAN bus network of each family.Sub-district intelligent network management control desk also comprises a Network Interface Module, is connected to exterior I nternet net, and remote control terminal need be connected the Internet net.

2) workflow after the warning node is reported to the police

The abnormality detection module of the workflow intranodal as shown in Figure 2 after the warning node is reported to the police detects unusual back and produces warning message, and MCU receives to make behind the warning message and judges and be which kind of type of alarm and note.Next judge the mode of operation of current system.If the controlled mode that has the owner to be in then produces corresponding alarm signal according to corresponding type of alarm.If there is not the aggressive mode that the owner is in, system will detect PSTN simultaneously and whether the Internet network is available, if the PSTN network can be used, carries out alert notice with dialing the owner's number that is stored in advance among the MCU.If first number ring unanswered can continue to dial second.In case the number of connection is arranged, plays the warning message that records in advance immediately.If Internet is also available; The CAN transmitter of this node at first sends to the Household intelligent gateway control desk with warning message; After the CAN receiver of Household intelligent gateway control desk receives warning message; Then the CAN transmitter of this warning message through this node sent to the intelligent console, sub-district with warning message through sub-district CAN network, after the ICP/IP protocol conversion, the intelligent console, sub-district sends to remote console through Internet with this information and notifies the owner through CAN.This remote console can be owner's the fixing network equipment, also can be mobile network appliance.

3) owner receives the processing mode to reporting to the police behind the warning message

The owner receives behind the warning message has dual mode to the processing of reporting to the police:

Mode 1:, after remote console sends control information, at first arrive the sub-district control desk through distal end I nternet net; Sub-district control desk MCU judges information; If the Internet control information is then at first accomplished protocol conversion to control information, navigate to corresponding home (e) node.Send to family's control desk node to the control information after changing through sub-district CAN transmitter then.After family's control desk node CAN receiver receives control information, navigate to corresponding warning node, control information is sent to corresponding node by the CAN transmitter.CU is after receiving control information for the warning node M, makes corresponding warning and handles.

Mode 2:, after the owner receives warning message, can dial family's fixed line through the PSTN net rapidly through the PSTN net.After household intelligent control platform PSTN module receives this phone, at first detect ringing number, when detected ringing number reach predefined after, carry out the automatic off-hook operation, and require the input password.After password authentification is correct, can continue to provide voice suggestion, corresponding apparatus is made reporting to the police handle operation.
