  Common watchdog system for kiosk terminal by time progamable power controler/UPS

Disclosed is a Watchdog system for automatic recovery of terminal hang-up which utilizes the time programmable power controller/UPS that is equipped in KIOSK terminal. This system can automatically recover the hang-up that occurs on low end KIOSK terminal using consumer PC that is not implemented with built-in Watchdog circuit.

The hardware configuration of KIOSK terminal for this system is shown in Figure 1.

This configuration requires the following conditions;

1. The power controller/UPS should be able to set power output off/on by minute (or second) period.

2. The power controller/UPS should be able to set (and reset) off/on time remotely from PC.

The PC software flowchart for this system is shown in Figure 2.

This software requires the following conditions;

1. The off/on time should be scheduled considering the system timeout value in order to avoid unexpected power off/on. Typically, off setting is 3 minutes after and 4 minutes after for on setting when the system timeout is 2 minutes. 2. The WAIT time for CPU release should be shorter than scheduled off time. Typically, WAIT time is less than 1 minute.

Running this software in the background of PC application program, automatic recovery of terminal is executed by power off/on that is set before hang-up occurs.
