¿µ¹®³»¿ë¿ä¾à This standard is to establish HAL (Hardware Abstraction Layer) library for sensor device driver to execute Plug & Play, when you plug a sensor into the platform. Plug&Play sensor interface platform consists of support sensor node platform, Plug & Play sensor module and sensor device driver management. Sensor node platform and Plug & Play sensor module is connected to standardized H/W interface for accepting diversity sensor.
Plug & Play sensor module is embedded sensor. Sensor module is connected to sensor node. It is consist of sensor, sensor ID block, sensor device driver block, power control block and external interface. Plug & Play support sensor node platform is consist of sensor ID, device driver handling, sensor H/W interface Handling and approach sensor standard API.
For accessing a sensor node platform module and distinguishing sensor using Plug & Play base, sensor device driver must be embedded in sensor module which is constructed by the given rules. To achieve this, we need to establish the rule such as HAL device driver definition, data format and method.
HAL library is basically embedded in sensor module for this Plug & Play senor device driver and describe Hardware Abstraction Layer function which needs for developing sensor device driver to sensor device driver developer. and also it suggest how to code device driver by classifying sensor. Sensor device manager suggest for using the given rule.
