Design of Intelligent Monitoring System based on Single Chip Microcomputer

Abstract In the modern security technology system, because the intelligent monitoring system has a complex monitoring circuit, a wide range of implementation methods and a wide range of applications and development, intelligent monitoring system is a very important part of the system。 At present, the development of this system is very rapid, and the development trend of the whole system is digital, network and integration。

The development and update frequency of modern intelligent monitoring system is more and more rapidly, and the application of this system is more and more widely。 Using temperature and humidity sensors, as well as a camera collecting basic information and transformed into the amount of data, using wireless transmission module is connected with a single chip computer of wireless data transmission, the receiver will accept data information by digital to analog conversion display in the host。 Circuit is mainly used to detect the circuit module, video monitoring module, wireless transmission module and other modules to complete the design of the circuit。

This design uses the wireless transceiver module of the model is nRF905, nRF905 is a single chip wireless transceiver in the 433 ISM MHz band。 Configuration is very easy to use programmable SPI interface with mcu。 The module price is low, the transmission is only 9 DBM -10 output power, 12。5 MA in the receiving mode。 This is in power down mode makes very power saving。 Through the temperature and humidity sensor data transmission and is beyond the set threshold to determine whether the alarm, and then use the high speed D / a will be able to on the baby's health and status information to the effect of real-time monitoring on the host image modulation and demodulation。
