[0030] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present utility model, the embodiments of the present utility model are further described in detail below in conjunction with the accompanying drawings and implementation methods.

[0031] In view of the current problems of insufficient intelligent control and non-energy-saving operation of lighting in factory areas, the utility model provides a factory intelligent lighting control system to solve the problems of insufficient intelligent control and non-energy-saving operation of lighting in factory areas, improve the utilization rate of factory resources, and improve the intelligence and energy-saving level of factory lighting.

[0032] like Figure 1As shown, a factory intelligent lighting control system includes: a PLC controller 1, a LoRa wireless communication module 2, a current mutual induction switch, a contactor and a twilight switch. The PLC controller 1 is provided with a plurality of PLC nodes, each of which is provided with a PLC end of the LoRa wireless communication module. Each lamp group in the factory is electrically connected to a corresponding contactor arranged in a local control cabinet, and the contactor is used to control the lighting or closing of the corresponding lamp group. The contactor is connected to the load end signal of the LoRa wireless communication module, the current mutual induction switch is arranged around the contactor, and is connected to the load end signal of the LoRa wireless communication module, and the current mutual induction switch is used to monitor the current signal of the contactor coil and provide signal feedback. The load end of the LoRa wireless communication module and the PLC end exchange information through the formed LoRa communication network. The twilight switch is arranged in an open area of ​​the factory to detect the external light intensity, and the twilight switch is connected to the controller signal. The controller controls the conduction or disconnection of the contactor through the LoRa wireless communication module, and determines the fault monitoring or fault alarm of each lamp group according to the feedback signal of the current mutual induction switch.

[0033] Specifically, the intelligent lighting of the factory area based on LoRa technology forms a LoRa node through the LoRa wireless communication module, and the PLC controller sets multiple PLC nodes, each PLC node corresponds to a group of lights for control. The PLC controller and the lighting equipment control end are respectively provided with LoRa wireless communication modules, wherein the LoRa wireless communication module of the PLC controller can be directly connected to the PLC interface of the remaining kinetic energy equipment in the factory area, and the LoRa wireless communication module of the lighting equipment control end can be connected to the local control cabinet of the block light. The PLC node is connected to the LoRa node, and the LoRa node is connected to the lighting equipment and sensor equipment, wherein the twilight sensor is connected to the PLC node. Multiple PLC nodes can be set, and connected to the LoRa node and keep the number consistent. The twilight sensor is installed in an open area of ​​the factory area to detect the external light intensity. The twilight switch is connected to the spare input point of the PLC control cabinet of the kinetic energy equipment in the factory area, and the twilight switch threshold is set. When the light intensity is lower than the set threshold, the light turn-on signal is transmitted; when the light intensity is higher than the set threshold, the light off signal is transmitted. The current mutual induction switch has two functions. Function 1 is signal confirmation. When the visual control management page sends a start-stop signal, the current mutual induction switch monitors whether there is a current signal in the contactor coil for signal feedback. Function 2 is block lighting fault monitoring. The current mutual induction switch sets a current threshold. When the monitored block lighting current is lower than the threshold, the visual control management page sends a fault alarm, and maintenance personnel can quickly locate and troubleshoot. The factory intelligent lighting system based on PLC and LoRa technology realizes multi-mode control of factory lighting without changing the layout and line of the original block lighting in the factory, and centralized control of lights in different blocks, reducing energy consumption and operating costs; using the remaining PLC input and output interfaces of the factory kinetic energy equipment to complete the access of the LoRa wireless communication module of the PLC control end, improve the utilization rate of factory resources; through LoRa wireless communication technology, long-distance power line communication is changed to wireless communication, which effectively solves the problems of redundant circuit construction, high cost, and large engineering workload, and improves the intelligence and energy saving level of factory lighting.

[0034] The system also includes: a data acquisition server; the data acquisition server is connected to the PLC controller by signal, and the data acquisition server is used to perform data acquisition and control on each lamp group, as well as network management.

[0035] The system also includes: a client terminal; the client terminal is connected to the data acquisition server network and is provided with a visual management APP, through which the operator can visually control and manage each light group.

[0036] Furthermore, the client terminal includes any one of the following: a PC, a tablet computer, a smart phone, and a smart wearable device.

[0037] In actual applications, various outdoor lighting groups in the factory are connected to the contactors of the local control cabinet for the factory block lights. The current mutual inductance switch is installed in the local control cabinet and the contactor is connected to the load end of the LoRa wireless communication module. The twilight switch and the PLC end of the LoRa wireless communication module are connected to the PLC node. Each PLC node is connected to the data acquisition server. The client terminal of the visual control management page calls the data of the data acquisition server to control the outdoor lights of the entire factory in various modes.

[0040] In practical applications, such as Figure 2 As shown in the figure, the LoRa wireless communication module uses a wireless remote synchronous switch with 8 switch inputs DI and 8 relay outputs DO. At the LoRa load end, the current transformer switch measures the contactor coil current and connects to the wireless remote synchronous switch with one switch input. At the same time, the load contactor coil is connected to the wireless remote synchronous switch with one switch output. The 8-way input and output wireless remote synchronous switch is selected to improve the scalability of the system, reserve space for the system to improve intelligence by adding sensors in the future, and reduce subsequent transformation costs.

[0042] Furthermore, the visual management APP running on the client terminal is provided with a dusk intelligent mode, a timing control mode and a manual single control mode, so as to switch and control the various light groups in the factory area according to needs.

[0043] In actual applications, the client terminal of visual control management receives and processes various input signals based on PLC, and controls the operation of output devices, and is developed on the client interface through i FIX configuration software. The overall page developed presents an axial diagram of the factory area, in which the scale graphics and specific positions of the lights in the factory area are displayed, and the following functions are available in this interface: ① The centralized control of lights in all blocks of the factory is realized, and the lights in each block can be independently switched in three modes (twilight intelligence, timing control, and manual single control). Different modes of intelligent start and stop can be adopted according to the different functions of the lights in each block. For example, street lighting can be started and stopped according to the intensity of natural light outside, and landscape lights such as laser laser lights can be remotely controlled or timed to start and stop according to the special needs of the factory area. The parking space lights in the carport can be turned on at regular intervals only during commuting; ② The interface system presents the monitoring of dusk signals. The green state indicates that the intensity of external light is low, and the block lights under dusk intelligent control need to be turned on. The red state indicates that the intensity of external light is high, and the block lights under dusk intelligent control do not need to be turned on. Set up historical trend records to reflect daily start-up time, so as to change the threshold of dusk switch according to needs in the future; ③ Based on the current mutual inductance switch, the visual control management page can reflect the on and off status of the block lights, and display the current control mode and operating status of each block light.

[0044] Furthermore, the light group includes: street lights, landscape lights, laser lights, carport parking space lights and log lights.

[0045] The system also includes: a sound-controlled sensor; the sound-controlled sensor is arranged at a set position, and the sound-controlled sensor is connected to a switch input terminal signal of the wireless remote synchronous switch; the PLC controller receives the sound feedback signal of the sound-controlled sensor through the wireless remote synchronous switch, and controls the lighting of the corresponding lamp group according to the sound feedback signal.

[0046] Furthermore, the wireless remote synchronous switch adopts E861-DTU.

[0047] In actual application, the intelligent lighting system can be used to transform the intelligent lighting system in factories with PLC control technology without changing the lights or the main lines. The system has strong portability and low cost. In one example, intelligent start and stop can reduce the lighting energy consumption of the whole factory by about two hours a day. It is estimated that the electricity consumption can be saved by 35,700 yuan per year, and the investment can be recovered within one year.
