[0025] As follows:

[0026] Please refer to Figures 1-4,

[0027] The system mainly includes a hybrid lighting control system 001 composed of a wireless control gateway 1, a power line communication controller 10 and a power line communication lamp controller 11.

After the power line communication controller 10 is successfully paired with the wireless control gateway 1, the power line communication controller 10 is connected with each power line communication lamp controller 11 through PLC (since the NLC module is arranged in each of the lamp controller and the controller, each lighting device 13 does not need to be provided with an NLC in the whole system, so the number of wireless devices is reduced), and each power line communication lamp controller 11 can be increased or decreased according to actual needs, and each power line communication controller 10 can also load a plurality of PLC lamp drives, thereby loading more lighting devices 13 (the lighting device 13 can be a lamp tube or other lighting product).

[0034] Compared with the current lighting control system (including the current PLC lighting system), the new hybrid network lighting system (wireless and PLC wired hybrid control connection) provided by the scheme aims to combine the stability of the wired PLC control system and the flexibility of the wireless NLC module. The PLC module is responsible for providing reliable connection, and the NLC module provides additional wireless connection points, which can conveniently add or remove lighting devices.

[0035] And the scheme can also be expanded into various control forms, such as system mode, simple mode - a mode with a panel but without a controller.

[0037] In the whole lighting control system, the NLC is used as the front-end wireless control gateway 1, which not only has the characteristics of stable transmission, high safety and high efficiency, but also has the characteristics of convenient regulation and control and installation. The PLC controller connected with the NLC gateway can be installed indoors or outdoors in the form of a control panel (similar to a switch panel), and after being connected in the form of PLC, it has the characteristics of multi-dimensional adjustment, such as adjusting power, color temperature and timing intelligent adjustment.

[0040] A preferred embodiment of the present application: the mixed lighting control system 001 further comprises a data acquisition module 15 connected with the wireless control gateway 1. The data acquisition module 15 comprises an illumination sensor, an occupancy sensor and an environmental sensor. The data acquisition module 15 is an information acquisition module with a wireless module, and the data acquisition module 15 is connected with the wireless control gateway 1 through wireless signals.

[0041] The illumination sensor in the present scheme is used to adjust the illumination of the client lighting 13 after sensing the external illumination condition; the occupancy sensor detects whether each drive and lighting 13 is working normally; and the environmental sensor detects the use environment and regulates the working condition of each lighting 13 according to the actual use environment.

The data acquisition module 15 can also be wirelessly connected with the wireless control gateway 1 (NLC gateway) through wireless (Bluetooth), so the data acquisition module 15 can be arranged in each area to be detected.

[0042] A preferred embodiment of the present application: the wireless control gateway 1 is further connected with an application program 14, which can be installed in a portable device with a wireless module (or other wireless communication characteristics).

[0043] The application program 14 can be used as a control terminal of the wireless control gateway 1, and the application program 14 can be a portable device with a wireless module, such as a mobile phone, a notebook computer or a tablet computer. Through these application programs 14, the gateway can be monitored and deployed in real time.

[0044] A preferred embodiment of the present application: the mixed lighting control system 001 further comprises a security encryption module 2, which comprises a first security feature metadata 20 and a second security feature metadata 21 arranged in the power line communication controller 10 and the power line communication lamp controller 11 respectively, and further comprises an encrypted data storage module 23 and an encrypted data processing module 22 arranged in the power line communication controller 10.

[0045] Thanks to the characteristics of the mixed network, the security encryption module 2 is integrated on the PLC panel (power line communication controller 10), which realizes the identification of security devices and the inapplicability of stopping of unfamiliar devices by matching the feature values (feature codes). The security encryption methods in the prior art are various, and as a preferred scheme of the present technical scheme, the two device terminals (i.e. the power line communication controller 10 and the power line communication lamp controller 11) with NLC modules are more suitable for feature value encryption. The feature value can also be understood as a security certificate or other encrypted data forms prearranged in the above two devices.

[0046] In a preferred embodiment of the present application, the first security feature metadata 20 and the second security feature metadata 21 are factory pre-set value feature data, including device name, number, alphanumeric string, and various feature code data of the device.

[0047] In a preferred embodiment of the present application, the operation mode of the security encryption module 2 includes that the power line communication controller 10 sends a request to the wireless control gateway 1 through the encryption number processing module, and the request content is the first security feature metadata 20, and the wireless control gateway 1 returns permission matching data to the encryption number processing module; after the encryption number processing module obtains the permission matching data, the first security feature metadata 20 is decoded into the second security feature metadata 21 matched with the first security feature metadata 20; since the second security feature metadata 21 is pre-stored in the power line communication lamp controller 11, when the second security feature metadata 21 in the power line communication lamp controller 11 matches the second security feature metadata 21 decoded by the encryption number processing module successfully, the power line communication lamp controller 11 is allowed to be connected to the network. In addition, the security encryption module 2 also has the characteristics of facilitating the addition and deletion of devices without complex network setting, debugging and other complex operations, for example, when a group of PLC drives is damaged (or lost), since the security encryption module 2 is provided with the encryption data storage module 23, the same PLC drive device as before can be directly installed without repeated setting. If a group of PLC drives is added, it can be allowed to be added at the NLC gateway end, and the operation data of the entire added and deleted devices in the system are retained in the encryption data storage module 23 for calling.

[0050] If the second security feature metadata is pre-stored in the power line communication lamp controller, when the second security feature metadata pre-stored in the power line communication lamp controller matches the second security feature metadata sent by the power line communication controller successfully, it indicates that the power line communication lamp controller has been correctly networked, and the network access is abandoned;

[0051] If the second security feature metadata is not pre-stored in the power line communication lamp controller, the power line communication lamp controller saves the second security feature metadata, opens the network access, and ensures that the second security feature metadata obtained by encrypting the feature value data of the network access device by the local certificate matches the pre-stored second security feature metadata;

[0052] If the second security feature metadata has been pre-stored in the power line communication lamp controller, but when the pre-stored second security feature metadata in the power line communication lamp controller does not match the second security feature metadata sent by the power line communication controller, the power line communication lamp controller re-enters the network and ensures that the second security feature metadata obtained by encrypting the feature value data of the network entry with the local certificate matches the pre-stored second security feature metadata.
