[0002] In large industrial enterprises such as the petrochemical industry, the lighting system is one of the key infrastructures to ensure production safety and improve work efficiency. Since the production equipment in the petrochemical industry involves dangerous environments such as high temperature, high pressure, flammable and explosive, the lighting system must not only provide sufficient brightness and stability, but also ensure that it can flexibly respond to different needs during production.

[0003] In the existing technology, many enterprises still use the traditional timing control method to manage regional lighting, but this method has some obvious limitations, resulting in the lack of energy management and operating efficiency of the lighting system. This leads to problems such as slow response speed of the lighting system, large energy waste, and high labor management costs. Summary of the invention

DETAILED DESCRIPTION

[0023] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0024] The petrochemical industry is an industry with continuous production throughout the year and highly concentrated equipment. It has the characteristics of complex operating procedures, numerous equipment and dangerous production environment. In this environment, it is crucial to ensure the safety, stability and efficiency of the production process, especially the application and management of the lighting system. In the production process of the petrochemical industry, various dangerous factors such as high temperature, high pressure, flammability, explosion, corrosion and poisoning are often encountered, and major accidents may be caused by the slightest carelessness. Therefore, the lighting system in this industry is not only to meet the basic visibility requirements, but also an important part of ensuring production safety, improving work efficiency and reducing accident risks.

[0025] Production facilities in the petrochemical industry usually need to run 24 hours a day, especially during nighttime production, where lighting requirements become particularly prominent. Production facilities often cover a large area and involve multiple links and areas, and different production workshops or facilities have different lighting requirements. Due to complex operations or difficult equipment maintenance, some areas often require continuous lighting, and even some equipment lamps require to be turned on 24 hours a day. Under such high-intensity and high-frequency lighting conditions, the energy consumption and maintenance difficulty of lighting equipment are particularly prominent.

[0026] Traditional lighting systems are often managed in a variety of ways, including manual control, timing control, astronomical control, and light sensor control. Among them, timing control is the most common one. However, with the complexity of production equipment in the petrochemical industry, traditional lighting control methods have exposed a series of problems. They mainly include the following aspects:

[0027] Slow lighting control response time: In emergency situations, the turning on or off of lamps often cannot respond in time, resulting in the lighting in some areas being unable to meet immediate production needs, which may affect the work efficiency and safety of operators.

[0028] High manual management costs: Traditional manual control and timing control modes require a lot of manual intervention and management, and cannot achieve real-time optimization and centralized control, resulting in cumbersome and inefficient management.

[0029] Long ineffective lighting time: Due to the lack of intelligent adjustment and automated management, the lighting system often has ineffective lighting, resulting in energy waste. For example, in areas where lighting is not needed, lamps are still turned on for a long time, or the lighting intensity in some areas is not adjusted in time according to actual needs.

[0030] Difficulty in equipment maintenance: In large-scale refining and chemical enterprises, there are a large number of lighting lamps and they are widely distributed, making equipment maintenance and replacement difficult. Especially in some dangerous areas or high-temperature and high-pressure environments, the life of lighting equipment is short and fault repair takes a long time, which can easily lead to lighting interruptions and affect production safety.

[0031] Voltage fluctuation problem: In the production process of petrochemical equipment, the start and stop of high-power motors often cause voltage fluctuations. These fluctuations not only affect the stability of the lighting fixtures, but also have an adverse effect on the service life of the lamps, leading to frequent failures.

[0032] Lighting systems are a major consumer of electricity, especially in production facilities in the petrochemical industry, where there are a large number of lamps covering a wide area and continuous lighting is required in multiple production links. Traditional lighting control systems cannot automatically adjust the brightness and switch status of lighting according to actual needs, resulting in a large amount of energy waste. In many cases, even if the production equipment is idle or underloaded, the lighting lamps are still turned on, failing to achieve an accurate match with actual needs.

[0033] In addition, traditional lighting systems mostly use timed control, which can achieve lighting management in some areas, but it is difficult to make flexible adjustments for detailed lighting needs, such as seasonal changes, weather changes, or special production process requirements. This makes the lighting system significantly insufficient in providing comfortable lighting and energy saving.

[0034] To solve the above technical problems, Figure 1 As shown, the present invention provides a lighting system, which is applied to multiple lighting areas. The lighting system includes a lighting lamp 10, a power supply circuit 20, a lighting controller 30 and a video lighting control workstation 40.

[0035] A plurality of the illuminating lamps 10 are provided in each of the illuminating areas. A power supply line 20 is connected to the illuminating lamps 10, and a switch is provided on each of the power supply lines 20. The illuminating lamps 10 are connected to a power source through the power supply line 20. A switch is provided on each power supply line 20 to control the on and off of the current. These switches can accurately control the working state of the illuminating lamps 10 in the illuminating area. The power supply line 20 includes L1-LN

[0036] A light controller 30 is provided for each lighting area. The light controller 30 is connected in series to the power supply line 20 to control the on / off of the power supply line 20 of a single lighting area. The function of the light controller 30 is to control the power supply line 20 of each area in series, adjust the working state of each lighting area separately, and ensure the independence and flexibility of the system. For example, when a certain area does not need lighting, the power supply line 20 can be disconnected by the controller to save energy.

[0037] In an optional embodiment of the present invention, the light controller 30 has 8 switch inputs and 8 magnetic latching relay switch outputs, and the contact capacity of the light controller 30 is 20A / AC220V. The 8 switch inputs allow the access of switch signals (such as buttons, switches, etc.). Through these input signals, the controller can receive switch status information from field devices (such as manual buttons or sensors). This means that the manager can trigger the action of the light controller 30 (such as turning on or off the light) through an external device.

[0038] The magnetic latching relay is a relay that maintains the switch state, with high reliability and low energy consumption. Each output can independently control a lighting circuit, and the maximum supported current is 20A (AC220V), which is suitable for most lighting control applications. Through these outputs, the light controller 30 can directly control the switch of the lamp.

[0039] The contact capacity is 20A, which means that each relay has a load capacity of 20 amperes and supports a voltage of AC220V. This high-capacity output can meet the needs of common commercial and industrial lighting systems and is suitable for controlling larger power lamps.

[0040] These switching outputs support manual operation, which means that the lights can be turned on and off directly via physical buttons or on-site control devices. This support for manual operation ensures that operators can still control the lighting equipment in the event of a system failure or communication interruption.

[0041] The light controller 30 uses the Modbus communication protocol to exchange data with the host computer. The controller establishes Modbus communication with the serial port server 70 by configuring its internal communication parameters. The serial port server 70 can transmit Modbus protocol data through the network, allowing the system to communicate across a large distance. Therefore, multiple light controllers 30 can be connected to a central monitoring system through the serial port server 70 to facilitate remote management.

[0042] The video light control workstation 40 is connected in communication with all the light controllers 30, and is configured to control the operation of each light controller 30 according to the image information and time information. The video light control workstation 40 is the core control platform of the system, which is connected in communication with all the light controllers 30, and adjusts the operation of the light controllers 30 in each lighting area according to the real-time image information and time information. The video light control workstation 40 is responsible for the centralized management of the lighting devices in all subordinate areas. Usually, various types of equipment monitoring information are integrated at this level, and a user-friendly interface is provided through the WEB terminal. Through the user interface accessed by the WEB browser, managers can view the lighting status of each area, perform control operations, and view relevant data of the lighting system (such as energy consumption, working status, etc.).

[0043] Image information: The actual situation of each lighting area is obtained through the video monitoring system. The workstation can obtain image data in real time to determine whether the lighting intensity needs to be adjusted or the lights need to be turned on or off. For example, if staff activities are found in a certain area, the system can automatically turn on the lighting.

[0044] Time information: Combined with time management, the system can automatically switch lighting modes according to different time periods. For example, the lighting intensity is automatically reduced during the day, while maintaining high brightness at night.

[0045] The workstation can realize lighting control of the entire device, that is, start or shut down the entire lighting system at the same time. This function is very suitable for large facilities or places, such as industrial parks, warehouses, production workshops, etc. This centralized control method can effectively reduce the tediousness of manual operation and improve management efficiency. In addition to overall control, the workstation also supports the start and stop of lighting for a single area or device. For example, when a specific area does not need lighting, the lighting of that area can be turned off through the workstation without affecting other areas. In this way, more sophisticated lighting management can be achieved and the flexibility of the system can be improved.

[0046] In an optional embodiment of the present invention, the video lighting control workstation 40 is configured to obtain season information and daily time information according to time information, and control the operation of each lighting controller 30 according to the season information and daily time information. The four seasons of spring, summer, autumn and winter are determined according to the change of the sun's position and the inclination of the earth's rotation axis, and the system can calculate the current season according to the rules of date and season changes.

[0047] Impact of seasonal changes: The length of day and night varies in different seasons, especially the balance of day and night in spring and autumn, with shorter daytime in winter and longer daytime in summer. The lighting system will automatically adjust the working hours and brightness according to seasonal changes. The time of day information is usually obtained through a real-time clock, combined with the sunrise and sunset times to determine the turning on and off of lighting.

[0048] According to seasonal changes, the video lighting control workstation 40 can perform the following controls:

[0049] Winter (short days, long nights): In winter, when the daytime is short, the system will automatically extend the lighting time and adjust the brightness of the lights according to the actual sunlight conditions (such as in the morning or evening).

[0050] Summer (long days, short nights): In summer, when daylight hours are longer, the system delays the time that lights are turned on, ensuring that they are only turned on when necessary (such as after sunset). In addition, the system can also adjust lighting usage based on factors such as climate and temperature.

[0051] Changes in sunrise and sunset times: The sunrise and sunset times vary from day to day, especially when the seasons change. The system will automatically calculate the appropriate light switch time based on these time points.

[0052] Distinguish between day and night: Based on real-time date information and changes in sunrise and sunset, the system will determine whether it is day or night and decide whether to turn on the lighting.

[0053] By using the daily time information obtained by the real-time clock, the video lighting control workstation 40 can control the lighting in the following manner:

[0054] Adjust lighting according to sunrise and sunset times: The sunrise and sunset times are different every day, and the system will automatically adjust the lights on and off according to these times. For example, the lighting needs to be enabled for a period of time before sunrise and after sunset, but not during the daytime.

[0055] Night lighting control: After sunset, the system ensures that lighting is turned on at the right time and adjusts light intensity according to regional needs to ensure a balance between safety and energy saving.

[0056] Automatically adjust brightness: Through automatic control, the system can adjust the brightness of artificial lighting according to the intensity of natural light during the day according to different time periods of the day; at night, it provides sufficient brightness according to actual needs.

[0057] In an optional embodiment of the present invention, the video light control workstation 40 is configured to obtain weather information based on the image information, and control the operation of each light controller 30 based on the weather information. Weather conditions (such as sunny, cloudy, rainy, haze, etc.) directly affect the intensity and distribution of outdoor natural light. The workstation can sense and judge the current weather changes based on the image information (such as the sky conditions and light intensity captured by the camera), and automatically adjust the brightness or switch status of the light.

[0058] Sunny day: If the weather is clear and the light is strong, the system will automatically reduce or turn off unnecessary indoor lighting to make full use of natural light.

[0059] Cloudy or rainy days: On cloudy or rainy days, when the outside light becomes weak, the system will increase the brightness of indoor lighting to ensure that the indoor environment is well lit.

[0060] Haze weather: In haze weather, the light is weak, and the system will increase the lighting intensity to ensure a safe working environment.

[0061] Automatically adjusting lighting based on weather conditions can maintain a good working environment and ensure that lighting is not excessive or insufficient, avoiding discomfort or safety issues caused by inappropriate lighting.

[0062] The camera (such as an environmental monitoring camera) equipped in the workstation collects image information of the environment in real time and analyzes the weather conditions. The camera can analyze the cloud density and brightness of the skyline through image recognition technology to determine the weather type. The video lighting control workstation 40 uses image processing algorithms (such as edge detection, brightness analysis, etc.) to extract weather-related information from the image data captured by the camera, and further confirms the current weather conditions in combination with weather forecast data.

[0063] In an optional embodiment of the present invention, the video lighting control workstation 40 is configured to obtain employee work information according to time information, and control the operation of each lighting controller 30 according to the employee work information.

[0064] Controlling the lighting system based on employee work and rest information can ensure that the lights are turned on and off in accordance with employee activity patterns during different work and rest periods, thereby achieving more efficient and energy-saving lighting management. The specific effects are as follows:

[0065] Lighting needs during work: When employees are working, the lights need to provide sufficient brightness to ensure work efficiency. The workstation can automatically adjust the brightness of the lights during the employee's working hours to maintain a comfortable working environment.

[0066] Automatic shutdown or adjustment during breaks: During employee breaks, the system can automatically turn off unnecessary lights or adjust the brightness to the minimum to reduce energy waste.

[0067] Optimize employee work experience: Through precise light management, workstations can provide a more suitable lighting environment, avoiding too dark or too bright light when employees are working, and improving comfort and work efficiency.

[0068] The workstation can obtain employees' working hours and rest periods by integrating data with the employee attendance system or smart devices (such as smart bracelets, attendance punch-in systems).

[0069] Working hours: Employees’ working hours can be determined through attendance data or wristband positioning and time recording.

[0070] Rest period: The employee's rest time can also be obtained through the attendance system or the activity records of the wristband. For example, when an employee is not active in the work area, the system can determine that he is resting.

[0071] like Figure 1 As shown, a video light control convergence switch 50 is provided between the video light control workstation 40 and each of the light controllers 30, and the video light control workstation 40 is connected to the video light control convergence switch 50 via RJ45 wiring. The video light control convergence switch 50 is the data transmission core node of the entire intelligent light control system, and undertakes the functions of data aggregation and transmission. It is responsible for receiving data from multiple light controllers 30 and transmitting the data to the video light control workstation 40. In other words, it is the "data aggregation hub" in the light control system. The video light control workstation 40 and the video light control convergence switch 50 are connected via an RJ45 interface, which means that the medium for data transmission is a standard Ethernet cable. This connection method is suitable for local networks or short-distance data transmission. The video light control convergence switch 50 plays a vital role as a "data transmission hub" in the system. It is not only responsible for collecting data from multiple light controllers 30, but also needs to efficiently forward these data to the workstation. The convergence switch must have a strong data processing capability to ensure that stable performance can be maintained when the system scale is expanded. By properly configuring the video light control aggregation switch 50, the scalability of the entire intelligent lighting control system can be greatly enhanced. As the system requirements increase (such as adding light controllers 30, adding monitoring points, etc.), the aggregation switch can flexibly expand interfaces and ports to support the access of more devices. Selecting a high-quality video light control aggregation switch 50 can ensure efficient and stable data transmission, avoid problems such as bandwidth bottlenecks, excessive delays or signal loss, and ensure long-term reliable operation of the system.

[0072] like Figure 1 As shown, a video light control switch 60 is provided between the video light control convergence switch 50 and the light controller 30, and the video light control convergence switch 50 and the video light control switch 60 are connected via a single-mode optical fiber. The video light control switch 60 is an important switching component in the system, located between the video light control convergence switch 50 and the light controller 30, and is responsible for managing and transmitting data streams. Its main function is to allocate and manage the flow of data, and may also include functions such as signal amplification and conversion to ensure smooth data exchange between various nodes in the system. The video light control convergence switch 50 and the video light control switch 60 are connected via a single-mode optical fiber, which shows that the data transmission between the two devices not only depends on the performance of the switch, but also utilizes the efficient transmission medium of single-mode optical fiber. The uplink data in the system is transmitted via optical fiber, which means that the data stream (such as sensor data, device status, etc.) sent from the video light control switch 60 will be transmitted via optical fiber to the convergence switch or a higher-level data center. This design can effectively improve the data processing capability and transmission stability of the system, especially in scenarios with large data volumes and high transmission requirements.

[0073] like Figure 1 As shown, a serial port server 70 is provided between the video light-controlled switch 60 and the light controller 30 , the video light-controlled switch 60 and the serial port server 70 are connected via RJ45 wiring, and the serial port server 70 and the light controller 30 are connected via RS485 wiring.

[0074] The serial port server 70 is a key communication protocol conversion device in the system. Its function is to convert the Modbus communication protocol and RS485 serial interface (which is usually used for communication between devices) into the TCP communication protocol and RJ45 interface. This conversion process allows devices that originally rely on serial communication (such as the lighting controller 30) to interact with network devices.

[0075] The serial port server 70 and the light controller 30 are connected via RS485, which means that the light controller 30 still communicates data via the RS485 standard. This connection method ensures stable communication between devices and is particularly suitable for industrial control and large systems. The serial port server 70 converts the IP data from the video light control switch 60 into RS485 format and sends it to the light controller 30, ensuring that the control signal can be accurately transmitted to each light controller 30.

[0076] As a bridge of communication protocols, the serial port server 70 enables devices that originally rely on traditional serial communication (RS485, Modbus) to interact with modern network devices (connected via TCP / IP protocol) to achieve remote control and flexible management. This design enables the intelligent lighting control system to be compatible with different types of devices and communication protocols, enhancing the scalability and flexibility of the system.

[0077] like Figure 1 As shown, a voltage regulator controller 80 is connected in series to the power supply line 20 corresponding to the lighting lamp 10. The voltage regulator controller 80 adjusts the output voltage by means of voltage reduction compensation so that it is always within a range suitable for lighting equipment. This method reduces the output power of the load by lowering the voltage, thereby achieving the purpose of energy saving. By lowering the voltage, the working burden of the lamp under high voltage is reduced, and damage caused by excessive or high voltage fluctuations is avoided.

[0078] Without affecting the lighting effect, the voltage regulator controller 80 can adjust the voltage to the lowest effective working voltage, which can reduce power consumption and achieve the effect of energy saving and emission reduction. Due to the reduced power output, the energy consumption of the lighting equipment is reduced, further reducing the operating cost.

[0079] High voltage and high current often cause impacts on lamps, which may damage the lamps or shorten their service life. The voltage regulator controller 80 avoids such impacts by stabilizing the voltage supply and effectively protects the lamps. This not only prolongs the service life of the lamps, but also reduces the maintenance costs caused by equipment failures and reduces the overall later operation and maintenance costs.

[0080] Lighting systems using the voltage regulator controller 80 have significant advantages in energy saving, protection and improved lighting quality. Through buck compensation technology, the voltage regulator controller 80 can adjust the voltage in real time, reduce unnecessary energy consumption, extend the life of lamps, and protect the equipment from voltage fluctuations. The use of autotransformers avoids harmonic pollution, improves the stability of the power grid, and provides more reliable power support for high-efficiency lighting equipment such as LEDs. Whether in commercial, industrial or home environments, this voltage regulator controller 80 can perform well and help achieve smarter and more energy-efficient lighting management.

[0081] The present invention also provides a petrochemical plant area, comprising the lighting system.

[0082] In summary, the present invention proposes a lighting system and a petrochemical plant, which forms an efficient and intelligent control platform by combining the existing video lighting control system and the device lighting voltage stabilization control system. This integration not only improves the overall performance of the system, but also makes lighting management more flexible and adjustable. The lighting efficiency in the production process is greatly improved, and the adaptability and flexibility of the lighting system are enhanced. For example, the system can adjust the lighting state according to factors such as weather changes, the operating status of production equipment, and personnel activities to ensure the best balance between lighting quality and energy saving effect. Users can set multiple lighting scenes on the WEB side according to different lighting needs and environmental conditions (such as day and night, working hours and non-working hours, etc.). This flexibility can ensure the best lighting effect while avoiding unnecessary energy waste. Lighting equipment can be grouped and controlled by area, lighting type or function, which makes the switching and adjustment of multiple lamps more efficient. Administrators can easily control the lighting status of an area or a specific group and improve management efficiency. Through the timing control function, lighting equipment can be automatically turned on or off at a preset time. This function is particularly suitable for the 24-hour operation environment of the petrochemical industry, avoiding the cumbersome manual operation and reducing human errors. Through WEB-side remote control, managers can monitor and adjust the lighting system anytime and anywhere, which is more flexible and convenient for daily management and emergency handling. Remote control helps to improve response speed and reduce unnecessary on-site operations.
