The invention discloses a vehicle-mounted pump truck frequency-off processing method and device and a controller. The method comprises the steps of judging whether the vehicle-mounted pump truck is successfully reconnected within first preset time or not when frequency of the vehicle-mounted pump truck is off; under the condition that reconnection succeeds, whether the frequency falling frequency of the vehicle-mounted pump truck in the single working time exceeds a first preset frequency or not is judged; under the condition that the first preset frequency is exceeded, judging that the frequency drop reason of the vehicle-mounted pump truck is strong interference; under the condition that the reconnection fails, whether the frequency falling frequency of the vehicle-mounted pump truck exceeds a second preset frequency or not is judged every second preset time; and under the condition that the number of times exceeds the second preset number of times, it is judged that the frequency drop reason of the vehicle
