[Abstract]:For the common intelligent home security monitoring system, the system terminal is fixed and installed by laying a bus in the home, and the terminal communicates with other devices through the bus. However, this way of installation has great limitations in the home. Based on this, this paper designs a kind of intelligent home security monitoring system, which is built on the mobile platform of intelligent car, which makes the system has strong flexibility. According to the need of function, a path memory tracking operation scheme is designed, and the fixed point monitoring and regular patrol monitoring function of the system are completed. The main work of this design is: 1. Combined with the development and present situation of smart home at present, this paper puts forward a kind of intelligent home security monitoring system based on ARM11 and Linux operating system, which is carried on intelligent car. The movement of the mobile platform is analyzed, which provides a theoretical basis for the control of the mobile platform. According to the functional requirements of this design, the speed measurement of the reflective photoelectric tube and the transmission photoelectric tube are analyzed. This paper analyzes the principle of laser ranging, infrared ranging and ultrasonic ranging, compares the advantages and disadvantages of magnetic flux gate, magnetoresistive type and Hall effect type of electronic compass, and selects the corresponding sensors to constitute a mobile platform. According to the need of this design, the circuit connection between each hardware module and ARM11 is analyzed and designed. The Linux system is built for the host computer and the target computer, and the driver program is designed for the photoelectric speed sensor and other hardware in the mobile platform. This paper designs and studies a kind of running scheme with path memory, and through the application program design of electronic compass and photoelectric speed sensor, make it work together to realize the track of memory path. 4, in order to realize the monitoring, The configuration of the Boa server and the configuration of the motion video server and the configuration and transplantation of the MPEG multimedia video processing tool are completed. The timing patrol function of the system is realized by using the Cron list in Linux. In order to enhance the monitoring ability of the system, the scheme of adjusting the lighting of USB camera automatically by using the photoelectric effect of photosensitive resistor is designed. Through the test of the whole system, it is shown that the function designed according to the corresponding theoretical basis is basically realized. Finally, the error of the system is analyzed, and a preliminary method to overcome the error is put forward. In this paper, the biggest innovation in the design of smart home security monitoring system is to design and develop a track operation scheme using memory bank instead of black line, aiming at the shortcomings of black line track running on mobile platform. The mobile platform can completely get rid of the black line, and the scheme uses artificial obstacles to plan the route, so that the designed security monitoring system can achieve patrol monitoring function and has higher adaptability and practicability.
