Description

Accessory warehouse wireless monitoring device based on ARM

Technical field:

The present invention relates to a kind ofly, relate in particular to a kind of accessory warehouse wireless monitoring device based on ARM based on embedded microprocessor ARM7 platform and wireless network communication technique.

Background technology:

In recent years, along with the development of embedded type CPU, embedded OS, embedded technology is used in the field that makes video monitoring etc. need mass data to handle becomes possibility.And the development of wireless communication technology and digital imaging technology makes the cable video monitoring begin to develop to wireless video monitoring.Traditional analog video supervisory system complex structure, poor stability, cost an arm and a leg based on concentric cable; The digital supervision technology has been broken away from not the constraint of wire communication; Thereby occurred based on wireless embedded video supervisory system, wireless transmission commonly used mainly is to realize through GPRS, CDMA, bluetooth, WLAN.The transmission speed of GPRS and CDMA technology is slow, stability is not high, communicating by letter is subject to the influence of surrounding environment, and Bluetooth technology is then used because of transmission range is short and received very big restriction.

Summary of the invention:

The present invention is exactly to the problems referred to above, and a kind of high accessory warehouse wireless monitoring device based on ARM simple in structure, stable is provided.

For reaching above purpose; The present invention adopts following technical scheme, the present invention includes monitor terminal, wireless network transceiver module and monitoring host computer, and its structural feature is that monitor terminal comprises sensor, camera, ARM development systems such as humiture, door magnetic, infrared, smog; The terminal has LCD display and keyboard; The wireless network transceiver module comprises wireless network card and wireless router AP, and monitoring host computer is made up of a PC, and host is accomplished program development, the debugging to development system.

The beneficial effect of the invention:

Realized Centralized Monitoring and management, also realized the remote wireless control of the humiture in the storehouse a plurality of storehouse safety cases in accessory warehouse.Through test, under the bandwidth of the average 1Mbps of wireless network, to the expressive ability of video clear and smooth, satisfied the monitoring requirement under the network teleconference, video monitoring and highly difficult, the complex environment, be with a wide range of applications.Because system has fully taken into account different application scenarios on hardware designs, leave bigger extending space, therefore believe that this system will have comparatively wide application prospect.

Embodiment:

The present invention includes monitor terminal, wireless network transceiver module and monitoring host computer; Monitor terminal comprises sensor, camera, ARM development systems such as humiture, door magnetic, infrared, smog; The terminal has LCD display and keyboard; The wireless network transceiver module comprises wireless network card and wireless router AP, and monitoring host computer is made up of a PC, and host is accomplished program development, the debugging to development system.

What terminal hardware adopted is the embedded hardware platform; Hardware platform is made up of core board and base plate two parts; Integrated 32-bit microprocessor S3C44BOX on the core board based on the ARM7TDMI kernel; Storer adopts the SDRAM of 8M joint to be responsible for the preservation of program run and intermediate data, and the NANFLASH of 16M byte is responsible for the preservation of source program and the historical data that power down need be preserved, event log, view data; Provide on the base plate: the 10M Ethernet interface, employing be the CS8900 chip interface, be used for and being connected of camera; The RS232 interface is used for communicating by letter with host, carries out the debugging of software etc.; The CF interface is used to connect wireless network card; The USBHOST interface adopts SL811HST, supports the equipment of USB1.1 standard, downloads kernel and file system when being used to debug; Keyboard interface, LCD interface are used to connect keyboard and display and carry out man-machine interaction, are divided into image capture module, sensor monitoring module, warning and communication module, four modules of human-computer interaction module.

The collection of image is responsible for by web camera; Select color eye HRM600GJ for use; HRM600GJ takes pictures after receiving the photographing command bag that S3C44BOX sends continuously; The static jpeg format of automatic shooting, resolution is 320 * 240, image is sent into arm processor through Ethernet interface and is handled.

Temperature Humidity Sensor adopts SHT11/15, and sensor characteristics is that semi-conductor chip (CMOS) and sensor technology are merged, and connects the I/O mouth of S3C44BOX through photoelectric isolating circuit; The AF-MC11 door status sensor is adopted in the door and window monitoring; Press when monitoring the key that opens the door, the electric control lock adhesive, goalkeeper opens; Be legal door opening state this moment, can not produce alarm; Under monitor state, door is opened by force, and then the output of door magnetic becomes high level by low level, and CPU detects door status sensor output high level, produces alarm, and CPU control output low level triggers siren and produces alerting tone to siren; Flue gas detect to adopt the AF-YG10X smoke detector, alarms to CPU when detecting certain density smog, when alarm takes place; CPU sends a warning message to the system monitoring main frame through the wireless network network; Monitoring host computer carries out analyzing and processing to warning information, and the space is taken precautions against and adopted the AF-HW01 infrared sensor, and the invader that gets in taking precautions against is responded to; The output high level is to CPU when having detected invader, and CPU carries out handled.

Siren connects the GPD3 mouth of S3C44BOX; When receiving the low level that CPU sends; Send alarm signal, the CF interface of S3C44BOX through base plate connects the wireless network card that adopts the Prism2 chipset to support the CF interface, successfully driven the CF interface after; Need WAP program Host AP be compiled in the operating system nucleus, use the bridge instrument that the 10MBit Ethernet and the wireless network bridge joint of S3C44BOX development board self are got up.

Human-computer interaction module is made up of keyboard and display, and keyboard adopts is 2 * 8 determinant keyboard, takes program controlled mode, and 1 connects the I/O line, and 1 connection external interrupt lines is a keyboard row line, and other 8 data lines are alignment; 16 buttons are divided into function key and numerical key, and numerical key is used for the input of password, the setting of data; Function key is divided into the key of setting up defences, disappear alarm key, the key that opens the door, cancel key, confirm key, the humiture display key; Press the key of setting up defences, it is low level that CPU detects the I/O mouth, and system gets into monitor state.
