Embodiment

As shown in Figure 1, embodiment provides a kind of Smart Home safety monitoring alarming system based on ARM, comprise the detector, ARM main control module, camera, alarm module and the monitoring equipment that are installed in tested point, the signal output part of described detector all inserts the signal input part of ARM main control module, and the ARM main control module is connected with monitoring equipment and video camera are two-way; Wherein monitoring equipment comprise by the two-way mobile phone terminal that is connected of GPRS module and ARM main control module with by the two-way computing machine that is connected of Internet network and ARM main control module.

Detector comprises the door magnetic detector of gathering gate signal, window magnetic detector, infrared eye, gas detectors and the smoke alarm of gathering the window opening and closing signal in the present embodiment.The ARM main control module is made up of ARM controller and connected FLASH, SDRAM and related peripheral circuit.The main effect of ARM controller is that warning input and output I/O (I/O) mouth and other parts are controlled in the system, therefore function such as realize that simultaneously acceptance is communicated by letter with transmitting video data, ethernet communication and GPRS network will be selected for use to have more universaling I/O port and the abundant chip of being convenient to make up peripheral circuit of peripheral resource.Present embodiment is selected the processor of the De $3C241O of Samsung as system for use.FLASH selects AM29LV16ODB and 28F128J3A for use, deposits bootloader (program loader) guidance code and system source program respectively.It is 64MB high speed dynamic RAM that SDRAM selects 2 HY57V561620 formation capacity for use.$3C241O is based on SOC (SOC (system on a chip)) chip of ARM9T, low-power consumption, high-performance, the exploitation mouth of very suitable embedded product.Have lcd controller, 3 passage UART, 4 passage DMA (direct memory access), IIC (Inerand Inter Chip) and SPI (Serial Peripheral Interface) bus interface, 117 universaling I/O ports, 2 USB (USB (universal serial bus)) host interface and 1 resource such as USB device interface.These resources of Ji Yu $3C2410 satisfy the requirement of total system to the ARM controller.

Be provided with image processing module in the ARM main control module, it is made up of image collection chip, image compression chip and related peripheral circuit.The hardware circuit that system adopts special-purpose collection and compression chip to form is realized the function of Flame Image Process, do not adopt software mode to realize, be in order to guarantee the real-time of safety alarm system, the burden that alleviates the ARM controller is so that Ethernet images and GPRS telecommunication, and can obtain digital compressed image preferably.All detectors and panalarm that system uses all are to link to each other with the ARM controller by GPIO (general input and output) to finish the function of warning input and output.Therefore yet these input/output signals all have very strong electric current, and are bigger to the interference of system, adopt TLP521 photoelectric isolated chip and relay that the warning input/output signal is isolated respectively, thereby drop to external signal minimum to the influence of system.
