Portable scoreboard system with motion sensing for providing theft prevention

摘要

A portable scoreboard system has motion sensing capability for providing theft protection. The system includes a main scoreboard and a remote control device. The main scoreboard includes a housing, a display panel configured to show predetermined parameters of one or more sporting events, a main microcontroller operating the display panel, a motion sensor unit responsive to movement of the scoreboard by sending an activation signal to the main microcontroller, an alarm operated by the main microcontroller and made to sound upon the main microcontroller receiving the signal from the motion sensor unit, and an RF receiver and antenna connected to the main microcontroller. The remote control device includes a casing, remote microcontroller, keypad for entering information related to the parameters of the selected sporting event to the remote microcontroller and determining the parameters displayed on the display panel of the main scoreboard, and an RF transmitter and antenna for receiving a signal from the remote microcontroller and for transmitting a remote signal to the RF receiver and antenna of the main scoreboard such that the main scoreboard is thereby operated by a user using the keypad of the remote control device.
