Program control method, device and system

The invention discloses a program control method, device and system and belongs to the field of internet. The method comprises the steps of acquiring sensor data through a sensor and sending the sensor data to a controlled device. The sensor data are acquired through the sensor in a control terminal and sent to the controlled device. The controlled device receives the sensor data sent by the control terminal and injects the sensor data into a virtual sensor, so that application program reads the sensor data from the virtual sensor and finishes various control operations according to the read sensor data. The problem that the application program in related technologies only can normally run in a sensor environment is solved. On the premise that any content of the application program is not modified, the application program which only can normally run in the sensor environment can also normally run in the controlled device without the sensor environment.
