Lighting and control device, terminal and positioning method thereof

The invention discloses a lighting and control device, a terminal and a navigation positioning method thereof. The method comprises the steps that the terminal receives wireless signals which are respectively sent by a number of lighting and control devices, wherein the coordinates of a number of lighting and control devices are marked on an electronic map pre-stored by the terminal; the terminal judges the signal intensity of a number of wireless signals; the coordinate corresponding to the lighting and control device with the most intense signal intensity in a number of wireless signals is selected as the current coordinate; and the terminal marks the current coordinate on the electronic map to complete positioning. According to the invention, lighting, information transmission and positioning systems are integrated; the wiring complexity is reduced; the positioning coverage area is increased; and construction and use costs are reduced.
