The adjustment process from step S51 to step S58, taking the adjustment of the first classroom lamps 1-1, 1-4 and 1-7 in the automatic mode as an example, 1140-64 (adjustment levels) × 10 (brightness corresponding to each level), which should be 500 per cent by reason, after the first adjustment, the light collection device 2-1 is still collecting the luminous intensity, at this time, the collected assumption is 600, then 1140 and 600 are 540, and the brightness divided into each level corresponds to 540/64 and 8.4, then the adjustment at this time is that the actual 600 is 100 higher than 500, each level is 8.4, then the new adjustment level of each light source is (600 and 500)/8.4, the adjustment is carried out according to the step until the luminous intensity collected by the light collection device 2-1 is 520-530 lumens, and the adjustment process is finished.

In a second aspect, the present application provides a dimming only system, as shown in fig. 5, including: the system comprises an intelligent light source, light acquisition equipment, human body induction equipment, a control panel, a data processing center, a network and a mobile terminal;

the intelligent light source, the light acquisition equipment and the human body induction equipment are connected through a network, the control panel and the data processing center are connected with the mobile terminal through the network, and the mobile terminal is connected with a cloud end through the network;

the intelligent light source is used for receiving the adjusted luminous intensity of the light source transmitted by the network, and adjusting the luminous intensity of the intelligent light source according to the adjusted luminous intensity of the light source;

the light collection equipment is used for collecting the current luminous intensity and transmitting the current luminous intensity to the data processing center equipment through a network;

the human body induction equipment is used for acquiring whether a person exists in the current space or not and transmitting the acquired human body induction equipment information to the data processing center equipment through a network;

the control panel is used for starting different dimming modes according to application scenes;

the data processing center is used for receiving the light acquisition equipment information and the human body induction equipment information according to the dimming mode and the dimming rule, calculating the adjusted luminous intensity of the light source and sending the adjusted luminous intensity of the light source to the intelligent light source through a network;

the mobile terminal is used for setting different dimming modes and corresponding dimming rules and storing the dimming rules to the cloud end, or the mobile terminal is used for receiving the dimming modes and the corresponding dimming rules stored by the cloud end, transmitting the dimming rules to the data processing center and transmitting the dimming modes to the control panel;

the network provides wireless communication network for each node of connecting in the network, and this application example 1 ~ 4 adopt like the network architecture of fig. 5, all adopt bluetooth MESH communication between intelligent light source, light collection equipment, (window) curtain or curtain, human response equipment, the control panel, and pass through bluetooth MESH communication links to each other with the gateway and connects, or pass through BLE bluetooth MESH with mobile terminal is connected. The network is connected with the router through the WiFI or the limited network, and the router accesses the cloud server through the public network REST API. And the mobile terminal accesses the cloud server through the 4G and 5G REST API. Wireless communication networks are well known to those skilled in the art, and are only specific examples of some network implementations, and any network implementation method is within the scope of the present application.

The data processing center is present in, but not limited to, one of the following devices: intelligent light source, computer, panel, cell-phone, server, control panel. In this embodiment, a data processing center exists in each of the intelligent light sources and initially specifies which of the intelligent light sources to employ as the designated data processing center for the cost classroom.

The smart dimming system also includes other smart devices connected to the network, including but not limited to window curtains, fans, curtains. This application can also be merged into other smart machine, for example when the projection mode starts, the system can stop the fan, opens the curtain, closes the (window) curtain, makes this mode humanized more like this, and its projection effect is better, need not artificially open or close these equipment manually, has saved the teaching latency.

In a third aspect, the present application provides a computer-readable storage medium, on which a computer program is stored, where the computer program, when executed by a processor, implements the smart dimming method according to the first aspect or any one of the possible implementations of the first aspect.

The present applicant has described and illustrated embodiments of the present invention in detail with reference to the accompanying drawings, but it should be understood by those skilled in the art that the above embodiments are merely preferred embodiments of the present invention, and the detailed description is only for the purpose of helping the reader to better understand the spirit of the present invention, and not for limiting the scope of the present invention, and on the contrary, any improvement or modification made based on the spirit of the present invention should fall within the scope of the present invention.
