1. An automated guided vehicle, comprising:
a first receiver configured to receive a first signal of a first frequency that is sent by a first transmitter equipped on a movable object or a fixed object;
a second receiver configured to receive a second signal of a second frequency that is sent by a second transmitter equipped on the movable object or the fixed object, wherein the second signal travels farther than the first signal; and
a controller configured to control operation of the automated guided vehicle according to whether the first receiver receives the first signal, to prevent the automated guided vehicle from colliding with the movable object or the fixed object equipped with the first transmitter, and control the operation of the automated guided vehicle according to whether the second receiver receives the second signal in the condition that the first receiver does not receive the first signal.
 
7. A method for controlling an automated guided vehicle, comprising:
turning on a first receiver equipped on the automated guided vehicle, the first receiver being configured to receive a first signal of a first frequency that is sent by a first transmitter equipped on a movable object or fixed object;
turning on a second receiver equipped on the automated guided vehicle, the second receiver being configured to receive a second signal of a second frequency that is sent by a second transmitter equipped on the movable object or the fixed object, wherein the second signal travels farther than the first signal; and
controlling operation of the automated guided vehicle according to whether the first receiver receives the first signal, to prevent the automated guided vehicle from colliding with the movable object or the fixed object equipped with the first transmitter, wherein the controlling operation of the automated guided vehicle comprises: controlling the operation of the automated guided vehicle according to whether the second receiver receives the second signal in the condition that the first receiver does not receive the first signal.
