7) mobile phone terminal creates Socket client: after creating, cell-phone customer terminal initiatively connects Cloud Server request and logs in, and logs in and successfully can monitor grain depot afterwards; In order to reduce network congestion, after mobile phone backstage receives the information from Cloud Server, advanced row data analysis, is stored to data buffer zone by grain depot monitoring and warning message, reads for correlation function interface, mobile phone foreground.
Further, the terminal node in described step 3) is each wireless senser, alarm and GPS/GPRS module.
Further, comprise GPS/GPRS terminal node in described step 3), this node is kept in touch by transmission " heartbeat packet " mode and telegon, and when this node is in ZigBee-network, devices illustrated is not stolen; When equipment is stolen, this nodal test, to obtaining Current GPS locating information after having departed from ZigBee-network and starting GRPS SMS, sends geographical location information residing for note annunciator to cell-phone customer terminal.
Further, the Socket client created in described step 6, wherein video acquisition module hardware uses " plug and play " camera module, and this module is connected with gateway by USB interface, utilizes the V4L2 tool software in built-in Linux to carry out video acquisition, compression and transmission.
Further, the cell-phone customer terminal described in described step 7), need build Android development environment and comprise following step: a) install Java JDK and configure on PC; B) Android SDK be installed and configure; C) installation Eclipse also configures and makes it combine with Android SDK.
beneficial effect
The present invention fully utilizes the technology of Internet of things such as built-in network, Android, Cloud Server, realize mobile phone multi-user " whenever and wherever possible " and synchronously wireless remote security monitoring function is carried out to grain depot, the positional information of tracking in time equipment, and monitor node can be deployed troops on garrison duty and withdraw a garrison flexibly according to demand.
