the parking brake system described above fig1 shows a flow chart 800 detailing one methodology associated with the automatic brake system 700 at 805 it is determined by the readers if the heavy equipment is in reverse gear if not the chart 800 loops back to 805 if so at 810 it is determined by the readers if a person is in the danger zone if not the chart 800 loops back to 805 if at 815 it is determined that a person is in the danger zone at 820 the hydraulic control causes the hydraulic cylinder to be depressed thereby depressing the de clutch brake pedal at 825 responsive to the de clutch brake pedal being depressed hydraulic fluid is moved to the disc brakes of the heavy piece of equipment causing the disc brakes to be applied thereby stopping the heavy piece of equipment at 830 responsive to the person being outside of the danger zone the hydraulic control releases the hydraulic cylinder and de clutch brake pedal by removing some or all of the hydraulic fluid acting on the hydraulic cylinder in another embodiment the driver of the heavy piece of equipment may manually release the hydraulic cylinder and de clutch brake pedal while previously detailed embodiments show multiple readers antennas fig1 a and 14 b show a single centrally positioned antenna 900 configured to read rfid tags 905 1 through 905 n in a defined danger zone 910 responsive to the antenna 900 receiving a signal from one.
