[0016] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] like Figure 1-3 As shown, a centralized lighting management device includes a mobile terminal 1, a server 2, a PLC 3 and a lighting device, wherein the lighting device includes a plurality of lighting lamps 4 and a plurality of relays 5, wherein the lighting lamps 4 are distributed in public places, and the relays 5 correspond to the lighting lamps 4 one by one;

[0018] The mobile terminal 1 is communicatively connected to the server 2, the server 2 is communicatively connected to the control input terminal of the PLC3, the iron core of the relay 5 is electrically connected to different output terminals of the PLC3 respectively, and the lighting lamp 4 is electrically connected to the power supply through the normally open contacts of the corresponding relay 5.

[0019] In this embodiment, the PLC 3 is electrically connected to the illuminating lamp 4. The PLC 3 controls the core of the corresponding relay 5 to close according to the instruction of the server 2, thereby connecting the normally open contact of the corresponding relay 5, so that the illuminating lamp 4 is powered on and emits light. Figure 3 As shown, K1 to K22 are relays 5, and H1 to H22 are lighting lamps 4.

[0020] In the centralized lighting management device, after the mobile terminal 1 is matched with the server 2, the user can use the mobile terminal 1 to control the PLC 3 through the server 2, so as to quickly and conveniently turn on or off the lighting lamp 4 without having to go to the switch in person. Due to the wireless remote control of the mobile terminal 1, there is no need to lay a large number of wires between the switch and the device, thereby reducing additional installation and maintenance costs. In addition, the design of using the PLC 3 can also reduce wiring and maintenance requirements, thereby reducing the overall installation and maintenance costs.

[0021] It is worth noting that the PLC3 includes a main body module 6 and a plurality of output modules 7, and the plurality of output modules 7 are detachably connected to the main body module 6. The plurality of illuminators 4 form a plurality of lighting groups, and the illuminators 4 of different lighting groups are electrically connected to the output ends of the corresponding output modules 7 through the normally open contacts of the corresponding relays 5. The design based on the mobile terminal and PLC3 is convenient for expansion and upgrading, and can adapt to the development of technology and changes in user needs. The PLC3 adopts a modular design, which is convenient for expansion or replacement according to different application requirements, specifically, adding or deleting output modules 7 to the main body module 6 to increase or decrease the lighting group, thereby enhancing the flexibility and maintainability of the system. PLC3 can independently control each illuminator 4. This design enables the device to accurately manage the status of each illuminator 4 and improve the efficiency of energy use.

[0022] Optionally, the public place is provided with a control box, and the PLC3 is arranged in the control box. The control box plays a role in protecting the PLC3 and the incoming and outgoing lines of the PLC3.

[0023] Preferably, the server 2 is a local server, which is arranged in the control box, and the server 2 is electrically connected to the control input terminal of the PLC 3 through a wire. The local server is arranged on site in a public place, and communicates with the control input terminal of the PLC 3 through a physical connection, and the local server is responsible for the transfer of instructions.

[0024] Specifically, the server 2 is a cloud server, and the server 2 is connected to the control input terminal of the PLC 3 through a wireless network. The cloud server does not need to be set up on site in a public place, so as to avoid damage caused by human or weather. The cloud server is connected to the control input terminal of the PLC 3 through a wireless network, and the cloud server is responsible for the transfer of instructions.

[0025] Preferably, the mobile terminal 1 is connected to the server 2 through the HTTPS protocol. In this embodiment, a QR code is attached to the surface of the server 2 or PLC3, and the mobile terminal 1 scans the QR code through the applet to match the mobile terminal 1 with the server 2, thereby realizing the communication connection between the mobile terminal 1 and the server 2. The mobile terminal 1 is a mobile phone. Using the QR code scanning function of the applet, the user can quickly control the lighting system. In this way, the operation can be completely based on the mobile terminal 1, without the need for additional hardware input devices. In the communication process between the applet and the server 2, encryption measures are adopted to ensure the security of data transmission. The simplified hardware design reduces the maintenance workload and cost. At the same time, control through the applet reduces the dependence on physical control equipment, so that the maintenance cost is low. Remote control reduces the operation of personnel near the lighting equipment and reduces the safety risk. The design of PLC3 takes into account the compatibility with existing lighting equipment, so that it can be easily integrated into the existing lighting system without large-scale transformation.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
