Abstract: The present invention provides a vehicle speed warning system and method for acquiring the images thereof. There is a speedometer image acquisition device, mounted correspondingly to the speedometer of the existing panel, and used to acquire the images of the speedometer. An image converter converts the images acquired by a speedometer image acquisition device into digital image data. A processor is used to receive digital image data and analyze the rotating angle of the pointer of speedometer. A memory stores the program of the vehicle speed warning system and digital image data of the speedometer. A display screen displays the speed value and/or the judgment result analyzed by the processor. The setting unit sets the warning threshold of the pointer angle of speedometer. A warning device, used to send a warning signal when the pointer angle of the speedometer exceeds the warning threshold set by the driver.

Abstract: The preset invention provides an Intrnet-based automatic security system and method. The security system includes a network server with a database, a network detection module and an automatic transmitting module, and a security device with a microcontroller, a virtual IP network module and wireless transmission module. The network detection module receives the information of security device and detects the networking state. The automatic transmitting module automatically transmits the alarm information from the network detection module to the client and security operator. The microcontroller links security components. The virtual IP network module employs a virtual IP address and links to a virtual IP router through a transmission interface. The security device also contains a polling module automatically linked to the network server for reading data.
