A microcontrolled, portable and inexpensive photometer is proposed. It uses a near infrared light emitting diode (NIR LED) as radiation source, a PbSe photoresistor as infrared detector and a programmable interrupt controller (PIC) microcontroller as control unit. The detector system presents a thermoresistor and a thermoelectric cooling to control the detector temperature and keep the noise at low levels. The microcontroller incorporated total autonomy on the proposed photometer. As its components ...

There are two main issues, high cost and interrupt response delay for current PACs (programmable automation controllers) which are using high frequency single-chip microprocessors and commercial RTOS (real-time operating system) working by switching the tasks and interrupts. To solve these problems, a new low-cost multi-core heterogeneous PAC structure was proposed. Based on the traditional front-end of interrupt service without interrupt switching delay and the division & deployment of multi real-time ...

The AKE392B converts the acceleration of ground motion into a series of digital signal, and this digital signal is transferred to the SC200AD-1 by the field bus EIA485. The PAC in the system is applied to collect the ground motion data, remove the non-seismic interrupts, access an earthquake’s intensity, carry out emergency ...
