[0017] The utility model is further introduced with reference to the drawings and specific embodiment as follows:

[0018] Embodiment:

[0019] Refer to Figure 1The embodiment provides a fatigue driving prevention system for a beam transport vehicle.

[0020] Each of the timing relays 5 is a normally open relay, and the timing relay 5 comprises a first-stage relay 5A, a second-stage relay 5B and a third-stage relay 5C which are connected in series.

[0021] The loudspeaker 8 is arranged on a series connection loop in which the third-stage relay 3C and the signal transmitter 9 are connected in series.

[0022] The vehicle body 1 is provided with an openable and closable wiring box slot 1A, and each of the timing relays 5 is arranged in the wiring box slot 1A.

[0023] The timing relay 5 is an adjustable relay structure with a hand-adjustable timing time limit and an LED display tube.
