The system integrator provides earthquake-monitoring systems for collecting earthquake information. In this project, 18 remote earthquake-monitoring stations positioned throughout the nation are to be monitored from a control center. The remote stations are spread out and in the middle of nowhere, and consequently the wiring for communication is extremely difficult and too expensive. GPRS communication is the best choice for this type of application. Previously, the earthquake monitoring system consisted of a GPRS modem, a single board computer, and an RS-485 I/O module, but this combination had many compatibility issues because of all the different components. For this reason, the customer wanted an all-in-one solution to integrate GPRS communication, configurable DIO channels, and serial ports into their new and improved earthquake monitoring system.
