Abstract: The present invention discloses an inspection method for early warning system of industrial security, in which the inspection steps for early warning system comprises: using inspection tool to collect signal characteristics regarding periphery of predetermined area; calculating on collected signal characteristics by means of processor in inspection tool through predetermined programs; determining, based on calculation results, error point of signal characteristics by means of processor in inspection tool; determining the time that abnormal phenomenon is about to occur by means of processor in accordance with data of error point, sending out warning information, and also transmitting collected signal characteristics via wireless transmission unit; and receiving characteristics information transmitted by wireless transmission unit by using wireless transceiver unit and then storing in built-in database for subsequent comparisons.

Abstract: A method for controlling a wireless smart display panel. The method uses a sensor to monitor environmental information, such as temperature or humidity, and the information is transmitted to a processor by using a wireless communication device that is compatible with IEEE 802.15.4. Moreover, the environmental information is converted to image information and displayed on a display device through the processor. Consequently, users understand outward environmental information in time.
