Embedded System Be Applied In Environmental Protection

Embedded system is a new direction of technique development. Embedded system has been applied in military, electronics, communication, industrial control and so on, because it has the character of small size, high performance, low cost, high reliability and oriented object program. Cause its application field and complex pitch deferent, formed two kinds of production. One applied in easy control, low required of real-time. Another applied in complex control, high required of real-time.As industrial development, we needed monitor and control source of empoison for 24 hours. It's based on device self-service. But the transmission of the data depend on lineate or sort-message of mobile. Wire-transmit is limited on physiognomy, sort-message is un-reliability and high cost.The intention of this topic is designing the embedded system of the inspect and control system of circumstance. It's applied GPRS and CDMA-Internet transmission, the main content of this article is:1. This article describes the development of embedded system, its classify, its applications in all kinds of fields and the direction of its development roundly.2. Hardware design of whole embedded system, based on the principle of embedded system design.3. Based on hardware of control, program the software.
