The process of the Bluetooth broadcast by the low-power Bluetooth module comprises the following steps: the method comprises the steps of detecting a current power supply type, adjusting the Bluetooth broadcast frequency to a first set frequency when the current power supply type is an internal power supply, adjusting the Bluetooth broadcast frequency to a second set frequency when the current power supply type is an external power supply, wherein the second set frequency is higher than the first set frequency, and through the adjustment and setting of the broadcast frequency, the power consumption is reduced as much as possible when the internal power supply is used, and the working duration of the low-power Bluetooth module is prolonged. And after the Bluetooth terminal enters the broadcast range of the Bluetooth equipment, pairing information is sent to the Bluetooth equipment through Bluetooth broadcast so as to request to establish Bluetooth connection.

During the concrete implementation, bluetooth equipment accessible and bluetooth terminal's bluetooth Signal connection, monitor the Received Signal Strength (RSSI, Received Signal Strength Indication) of bluetooth Signal in real time, real-time Signal Strength promptly, then just can calculate the prediction distance with bluetooth terminal according to real-time Signal Strength, the process includes: calling a pre-stored instruction; setting signal intensity and environment attenuation factors when the distance between the Bluetooth sending end and the receiving end is 1m according to a pre-stored instruction; and calculating to obtain the estimated distance according to the real-time signal intensity, the set signal intensity when the distance between the Bluetooth sending end and the receiving end is 1m and the environmental attenuation factor. The estimated distance calculation formula is as follows: d ═ 10^ ((abs (rssi) -a)/(10 ×) n)). Wherein d is the estimated distance in m; (ABS (RSSI)) is real-time signal strength which is a negative number, A is the absolute value of the signal strength when the set Bluetooth equipment is 1m away from the Bluetooth terminal, the optimal range is 45-49, n is an environmental attenuation factor which needs to be tested and corrected, and the optimal range is 3.25-4.5.
And S104, when the estimated distance is smaller than the first set distance, sending a starting instruction to the lighting equipment.
In specific implementation, the first set distance may be set according to an actual situation, for example, the first set distance may be set to 10m, when the user holds the bluetooth terminal to a position about 10m away from the bluetooth device, the bluetooth device sends an on instruction to the lighting device to turn on the lighting device, and similarly, if the user holds the bluetooth terminal to exceed 10m away from the bluetooth device, the bluetooth device sends an off instruction to the lighting device to turn off the lighting device. After sending the opening instruction to the lighting equipment, the Bluetooth equipment also correlates and archives the Bluetooth terminal identification code with the time of sending the opening instruction so as to fetch and consult the archive record. The Bluetooth terminal held by the user can be a mobile phone, a tablet personal computer, an intelligent bracelet, an intelligent watch and the like.

In specific implementation, the second set distance may be set according to an actual situation, for example, the second set distance may be set to 3m, when the user holds the bluetooth terminal to a position 3m away from the bluetooth device, the bluetooth device sends a maximum brightness instruction to the lighting device to turn on the lighting device with the maximum brightness, and similarly, if the user holds the bluetooth terminal to exceed 3m away from the bluetooth device, the bluetooth device sends a corresponding brightness reduction instruction to the lighting device to reduce the lighting brightness. The brightness adjusting process specifically includes: sending a brightness increasing instruction to the lighting equipment once when the predicted distance is reduced by the set spacing distance between the first set distance and the second set distance; and sending a brightness reduction command to the lighting equipment once when the predicted distance is increased between the second set distance and the first set distance and every time the set spacing distance is increased, and sending a closing command to the lighting equipment when the predicted distance exceeds the first set distance.
