Abstract
A system and method for generating remote incursion alerts in response to incursion detected by incursion transmitter units, such as at traffic cones, posts, barricades and signage. Alerts are generated in response to impacts detected at the safety icons within an incursion transmitter (or transceiver) and transmitted to one or more incursion receiver units which annunciate the alert with audio, lights, and or tactile output to warn construction crews of possibly impending danger. The alert signals may be communicated over a wired connection or a wireless communication link. Alert signals wirelessly communicated are preferably repeated by other incursion transmitters which are each coupled to a receiver to form a transceiver, wherein the distance and conditions over which the wireless alert signals may be communicated is extended. The incursion receiver may generate area alerts, or personal alerts, such as comprising the generation of audio, physical outputs, or light signals.
