The accompanying drawing explanation
Fig. 1 is the specific implementation circuit structure diagram of terminal handler of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
In Fig. 1, comprising: measurement and control circuit 3, image format conversion circuit 4, photoelectric isolation module 5, stacking-type image acquisition device 6 and warning circuit 7 and the information household appliances interface circuit 8 of large capacity Ethernet access and server 1, image data acquiring and transcoding module 2, control node.
Wherein, large capacity Ethernet access and server 1 one ends are connected in the broadband ethernet of registering one's residence, the other end is connected in image data acquiring and transcoding module 2 and controls the measurement and control circuit 3 of node, the variety of protocol and the various network services function that for completion system, need, as the configuration of the webserver, IP address etc.
Image data acquiring and transcoding module 2 are connected in hardware transcoding circuit 4, image format conversion circuit 4 other ends are connected in stacking-type image acquisition device 6 again, mainly complete the transcoding of indoor and outdoor scene image, and image transmitting is accessed and server 1 to large capacity Ethernet, and then be sent to far-end.Wherein, stacking-type image acquisition device 6 can be for a plurality of.
Hardware transcoding circuit 4 converts the form needed to for the DID that will be collected by the stacking-type image acquisition device.
The measurement and control circuit 3 of controlling node is connected in photoelectric isolation module 5, and photoelectric isolation module 5 other ends are connected in warning circuit 7 and information household appliances interface circuit 8 again.This circuit completes the wired and wireless transmission of indoor multi-analog and digital quantity, data for each measuring control point in collection and control room, in addition, because the information household appliances of most all provide the communication interface of standard, so can carry out data acquisition and control to household electrical appliances easily.
The following specifically describes structure of the present invention, implementation.
(1) structure of terminal handler
For ease of the installation in current all kinds of high-end residentials, make it unified with indoor environmental harmony, the volume of terminal handler strict control appliance in carrying out structural design, in the design of circuit, adopt multilayer wiring, end face and bottom surface be the mode of welding component simultaneously, dwindles the volume of circuit board.
(2) terminal handler realizes circuit
The specific implementation circuit of each functional module of terminal handler is described below, and mainly comprises the measurement and control circuit 3 of the collection of the large capacity Ethernet access of data and server 1, view data and transcoding module 2, indoor each measuring control point.
1, large capacity Ethernet access and server
The microprocessor of large capacity Ethernet adopts 32 hardware platforms based on ARM core, working method according to system, at first program code downloads in system flash and stores by jtag interface or serial port, when system starts, by special BOOT code, the program in flash memory is transported in internal storage, then jumps to the corresponding address of internal storage and carry out.
System select can be under single 3V voltage in-system programming or the flash memories wiped, for program code stored when static state, every flash memory provides the memory space of 1M * 16, two in parallel forms the code memory space of 1M * 32, can meet the code length requirement of native system Redhat fully.
Internal storage in system is for the running space of REDHAT and various application programs.With internal storage, compare, internal storage has advantages of that unit space memory capacity is large and price is cheap, is conducive to simplify system and improves cost performance.
Build flash memory and the internal storage system of 32, can give full play to addressing and the operational capability of 32 ARM microprocessors.
With traditional OS, compare, redhat is exactly in the situation that guaranteed the task for application-specific, reduces as far as possible other unnecessary part, with build one efficiently, reliable operating system moves specific task.
2, the collection of view data and transcoding module
H.264 the data of the transcoding module yuv format that just the stacking-type image acquisition device is exported are carried out the H.264 compression of form.H.264 by compressed image, connected to form, the every width of compressed image has quantization table and the huffman table of oneself relatively.H.264 can only use a quantization table and huffman table to be compressed continuous tens frames two field pictures even up to a hundred, only when data occur to lose, just need to again be written into quantization table and huffman table.Needed expense when this advantage greatly reduces the system video decoding.
Be sent to large capacity Ethernet access and network service circuit 1 by the pictorial data after format compression H.264, realize a webserver at this circuit simultaneously, when far-end has the request of browsing image data, the webserver just arrives far-end by image data high speed transmission, in addition, some necessary netconfig functions also complete at this, as configuration of IP address etc.
The The Cloud Terrace motion control is for adjusting the visual angle of stacking-type image acquisition device.
3, control the measurement and control circuit of node
Control the measurement and control circuit 3 of node for completing other indoor analog quantitys and the transmission of digital quantity, microprocessor adopts the ARM of 8 of a slices to realize, according to the position of equipment, provides the data communication circuit of multiple wireless, thereby reduces indoor wiring.The data volume that this functional module need to be transmitted is relatively less, but requirement of real-time is higher, while therefore realizing the data of this module are transmitted in large capacity Ethernet access and server 1, requires to have higher priority and real-time.
