    摘要: A system and method for detecting a proximity of a person to a machine includes a first transmitter unit carried by the person, a plurality of receiver units located on the machine at know locations, and a processing unit including data defining a first boundary around the machine. The first transmitter unit transmits a magnetic proximity signal having a predetermined signal strength and a predetermined signal frequency. Each of the plurality of receiver units is for determining a received signal strength of the received magnetic proximity signal. The processing unit: determines a location of the first transmitter unit relative to the machine based on the received signal strength of the magnetic proximity signal and the known location of the plurality of receiver units; and outputs a proximity warning signal if the location of the transmitter relative to the machine is within the first boundary around the machine.
