  • Patent number: 8818432
    Abstract: A method and an integrated routing device for controlling remote systems via short messages are provided. When a mobile communication device controls remote systems via short messages, the method and the integrated routing device verify whether the mobile communication device is a legal commander. When the mobile communication device is verified as a legal commander, the method and the integrated routing device generate a verification code and subtract consumed time caused by message relay from a first control duration to generate a second control duration. The mobile communication device performs remote control during the second control duration. By completing above procedure, the method and the integrated routing device are capable of preventing fatal damages resulted from missing the right timing for executing control commands, and can further improve the efficiency of controlling remote systems via short messages.

  • Patent number: 8396947
    Abstract: An active monitoring system for serial monitoring devices and the method thereof are provided. By receiving serial data from a serial monitoring device on a triggering device and analyzing the serial data to generate a device tag, the mechanism transmits the packed device tag actively to a server through a network. The server automatically generates a tag compliant with the Object Linking and Embedding for Process Control (OPC) according to the device tag for monitoring. The mechanism improves the compatibility and efficiency of monitoring and bandwidth usage.

  • Patent number: 7779124
    Abstract: An active monitoring system and method thereof are provided to solve the problems of no real-time monitoring and bandwidth usage in the prior art. A triggering end detects a monitoring device to generate a device tag. The device tag is packed and actively sent to the server end via a network. The server end automatically generates an OPC tag for an integrating server to use. The mechanism can increase monitoring efficiency and bandwidth usage.
