Tutor description

The WAMRCS uses sampling circuits and A/D convertor to transfer analog signal of voltage and current into digital data. The digital data then send to embedded system to compute power parameters. This embedded system will send power parameters to regional monitoring and control center of utility company via wireless module connected with it.

The WAMRCS uses sampling circuits and A/D convertor to transfer analog signal of voltage and current into digital data. The digital data then send to embedded system to compute power parameters. This embedded system will send power parameters to regional monitoring and control center of utility company via wireless module connected with it. This WAMRCS applied on distribution automation can save personnel expense of hiring reading-meter workers and can be free from human involvement; more over it can save large man power from keying utility usage into data base.CHAPTER 22.1 BLOCK DIAGRAM:[pic]CHAPTER 3LPC 2148 ARM PROCESSOR3.1 LPC 2148 CPU:The LPC2148 microcontrollers are based on a 32/16 bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combines the microcontroller with embedded high speed flash memory ranging from 32 kB to 512 kB. A 128-bit wide memory interface and unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty. Due to their tiny size and low power consumption, LPC2148 are id
