For another example, the request type information is "sensors/rtk/raw/pack", the sensor corresponding to "sensors/rtk/raw/pack" is an RTK sensor, so the RTK sensor is determined as the target sensor.

In one embodiment, the identification information of the target sensor is sent to the control terminal, so that the control terminal displays the identification icon of the target sensor according to the identification information. The identification icons of different target sensors are different. By displaying the identification icon of the target sensor on the control terminal, the user can know the sensor currently used by the movable platform. For example, as shown in FIG. 6 , a status indicator bar is displayed in the display interface of the control terminal, and the status indicator bar is located in the top area of the display interface, and the status indicator bar displays the identification icon corresponding to the GPS sensor. Therefore, the user can know the control The controller uses the sensing data of the GPS sensor to control the movable platform, and the status indicator bar also displays the icon of image transmission, the icon of obstacle avoidance module, the icon of communication connection, the icon of network and the icon of battery.
