Sentinel Alarm System Based On Multiple Wireless Modes

The Chinese Armed Police Force is responsible for the maintenance of domestic security and stability. Watch and ward, prison and detention guard, throughout the country.It has a large number of posts. So to establish a rapid and convenient, scientific and effective alarm system is very urgent and important. This paper focuses on the actual task and demand of the CAPF, To designed and come true the Sentinel Alarm System Based On Multiple Wireless Modes.Firstly, through the investigation and analysis bear detain, guards and other tasks of the grass-roots of CAPF existing alarm status, a more flexible and efficient design scheme is put forward aiming at the defect exists in the way. According to the investigation and analysis, in the past, the alarm system has a range of small, short distance, slow time, flexibility, etc.. In view of this situation, the scheme in the previous sentinel alarm on the basis of the system designed the Sentinel Alarm System Based On Multiple Wireless Modes.Secondly, in the scheme based on. Specific design of the the sentinel alarm hardware and software of the system, and designing of the PC system. The hardware part mainly includes the infrared remote control module, the terminal MCU module, the ZigBee terminal module and the ZigBee coordinator module, the GSM short message module and the MCU module. After the discovery of the sentinel, press the infrared remote control button for the alarm, the alarm signal through the ZigBee network transmission to the central control MCU, and then the central control MCU SMS module to send alarm messages. The computer of the squadron duty room and the detachment duty room is connected with the mobile network via the short message module, and the alarm message is received. At the same time, the officers of the squadron and the detachment received alarm messages by mobile phone. The PC systerm can query alarm units and sentinel according to the alarm number, as well as force allocation, number of sentinel, target unit, address, squadron officers, contact the important basic information. To ensure in the first time to acquire the alarm information, the officers at all levels to make effective decisions in a timely manner and quickly dispose of the event, to minimize the loss and risk. In the developed of software programming, used the interface function to encapsulate the hardware, so that the modules are independent, and the interaction between the modules and the system is clear and easy to understand.Finally, the test of each module and the whole system is carried out. The test results show that the system can effectively alarm and achieve the expected goal.
