Development of Wireless Automatic Checking System for Emergency Lights via Internet

This paper develops a wireless automatic checking system for a number of emergency lights at the same time via Internet. The proposed system can check the status of emergency lights including the battery with charger using a Microprocessor-based Detector in a scheduled period. Every emergency light is assigned a respective identification number. Then, the Nearby Transmitter/Receiver Module can transmit the checking results to the Remote Transmitter/Receiver Module. Also, the Nearby Computer is linked with the Microprocessor-based Data Processor that connects with the Remote Transmitter/Receiver Module via RS232. Using TCP/IP, the Remote Computer can communicate with the Nearby Computer for a long distance via Internet. Accordingly, all checking outcomes received by the Nearby Computer can be transferred to the Remote Computer for monitoring and recording. Furthermore, the Remote Computer can send the control signals to the Microprocessor-based Detector for a remote real-time checking operation. Experimental results confirm that the proposed system design presents a good performance in term of robust, stable, and fast response.
