Control method, device and system based on conditional trigger sensor

Abstract

The invention discloses a control method, device and system based on conditional trigger sensors, and relates to the field of the Internet of Things, and the method comprises the steps: creating virtual sensors corresponding to all entity sensors and logic states of the virtual sensors; establishing a virtual sensor state mapping table, wherein the table represents a mapping relationship among the identifier of the entity sensor, the identifier of the virtual sensor, the logic state of the virtual sensor and the discrimination condition of the logic state; the discrimination condition comprises a limiting condition related to the environment characteristics and a state threshold value of the corresponding entity sensor; wherein the same logic state can correspond to a plurality of discrimination conditions; sending the virtual sensor state mapping table to a gateway; establishing a control relation mapping table between the information of the virtual sensor and the state of each controlled device, wherein the information of the virtual sensor comprises the identifier and the logic state of the virtual sensor; and sending each control relation mapping table to the corresponding controlled equipment. According to the application, the later maintenance efficiency can be improved.
