A R&D Program for Prompt Response about Forest-Protection Information with Platform Display System
Global Positioning System (GPS)
GPS is used to measure the time and distance by satellites (Fig.2), and offers the global, all-weather, three-dimensional space, three-dimensional speed, continuous, immediately high precision navigation message (Liu ji-yu, 1993). The research only gather the message of the GPS's electromagnetic wave with the GPS receiver and calculate precisely the coordinates of the object's position, timing, and ranging by the theory of fore intersection at any movement and any place.
Presently, GPS is widely popularized to different business in the world. Those application include mounting, traveling, hunting, engineering, disaster protection, mapping, natural resource exploration, land development, space expand, scientific research, earth crust monitor, precise geodesy, intelligent transportation, vehicle navigation, and GIS investigation, etc.
"GPS User's Unit" indicates the GPS receiver, engine chip, or the processing board in the computer module (Fig.3 User's Unit). Those shape and size is quite different. The precise Geodesy type is bigger and heavier than the engine chip that is similar as a stamp.

Radio Imagine Transmitting
Internet technologies shorten human range and create a convenient life style. The problems that is derivative from the Internet cable would be urgent to solve, such as massive wiring engineering, long interval of system setting up, maintenance of the old fashion or damage set, etc. Fortunately, the wireless radio Internet technique (Fig. 4) is exploited and overcome those problems on time.

System Structure
The system can be installed on every Forest Protection-Management Offices and their workstations in the future. It is necessary to consider about the simple setting up, easier operation, quicker maintenance, etc. By using the system (Fig.5) the patrolmen record the coordinates of their patrol path into the hand held GPS receiver (Fig.6) automatically (Chou Ten-Yin) and enter the coincident definition code from the key board when they come across the illegal cutting, unlawful cultivation, collapse areas, etc.
The Interface in System
The systems include complete data transmitting and receiving interface (Fig.7). It can be installed in anyone compatible x86 computer, to transfer data mutually by transmitting interface. It is probable to install in notebook computer, so that rescuers can operate with the equipment in forest calamity region. Due to this reason, the design to establish in individual operating system in computer, is different from the dispersed structure (N-Tier) ° This individual operating system can keep best mobility and simplification, even if necessary, to set up temporary rescuing control commander to support rescuing work with installing one set of equipment.
