Claim 19:
20. An anti-collision method for ground vehicles operating in a work environment, comprising the steps of:
a) associating a first transceiver device with an obstacle, said first transceiver device being configured to generate and transmit one or more wireless signals, the first wireless signal carrying an obstacle identification code;
b) associating a second transceiver device with a ground vehicle, said second transceiver device being configured to generate and transmit one or more wireless signals;
c) transmitting said one or more wireless signals from said obstacle at pre-established time intervals;
d) the second transceiver device receiving said first signal which includes the obstacle identification code;
e) determining the trajectory of the ground vehicle and of the obstacle as a function of the signals;
f) determining the probability of collision between said ground vehicle and the obstacle as a function of the trajectory of the ground vehicle and of the obstacle;
g) generating and sending a signal that includes a probability of collision between the ground vehicle and the obstacle;
h) calculating a relative distance from the ground vehicle to the obstacle based on signal power of a signal received from the obstacle;
i) engaging in different types of information exchange with different vehicles, the first type is based on an initial request message containing a unique destination ID, wherein only a vehicle holding that ID can respond; and the second type is based on an initial request message directed to vehicles within a predefined range, wherein any vehicle within that range can respond.
